ANNUAL REPORT 2010 – KEY IT INDICATORS
1. INTRODUCTION
1.1 History
Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an
association of eight institutions with research and development in the field of
Telecommunications:
• Instituto Superior Técnico (IST);
• Universidade de Aveiro (UA);
• Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC);
• Portugal Telecom Inovação, (PTIn);
• Nokia Siemens Networks S.A (NSN);
• Universidade da Beira Interior (UBI);
• Universidade do Porto (UP);
• Instituto de Ciências do Trabalho e da Empresa — Instituto Universitário de
Lisboa (ISCTE-IUL).
it is organised around three sites: one in Aveiro, in the University Campus, another
in Coimbra, in Site II of the University of Coimbra and the third one in Lisbon, in
Instituto Superior Técnico. In addition there are four delegations:
• Covilhã, in the University of Beira Interior;
• Leiria, inthe “Escola Superior de Tecnologia e Gestão” of the Leiria Polytechnic
(IPL);
• Lisboa, in Instituto Superior de Ciências do Trabalho e da Empresa (ISCTE);
• Porto, shared by the Faculty of Engineering and the Faculty of Sciences of the
University of Porto.
Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros)
grant from Programme CIENCIA, through three contracts signed in 1991. This
investment enabled new infrastructures to be built and research laboratories to be
equipped at each site.
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994.
Since 1993, it activities proceed regularly.
7
it bylaws statutes were first approved in 1992, modified in 1997 and modified again
in 2003. New site bylaws deriving from it bylaws were approved and implemented
in 2005.
Key developments in 2010 are highlighted ahead. Details are included in the
sections dealing with each of the research areas.
1.2 Management
it is managed by a Board of Directors, elected by the General Assembly, and by
Site Management Boards, which include the site members of the Board of Directors.
Site Management Boards enjoy ample freedom to deal with current affairs and
usually meet weekly. The Board of Directors meets at least once a month.
it scientific activities are overseen by the Scientific Board, which includes all it
researchers holding a Ph.D. degree. The Scientific Board meets in Plenary or in
Committees,
both
permanent
and
temporary.
There
are
two
permanent
committees: the Science and Technology Committee and the Research Group
Coordination Committee.
it Work Plan and the Annual Report are discussed with the Advisory Committee,
formed by three independent experts in the field of telecommunications (Prof. Sir
John O’Reilly, Prof. Martin Tomlinson and Dr. Roland Huber) acting in a personal
capacity, and together with the Accounts (after legal certification) are subsequently
submitted to the General Assembly for approval.
The General Assembly met formally twice in 2010. The first meeting was held on
the 31st of May, in the Meeting Room of the Aveiro site, to discuss and approve the
2009 Annual Report and Accounts and to empower the Board of Directors to create
an it External Laboratory in Taguspark. The second meeting took place on the 22nd
of December, in the Chancellor Room of Porto University Club (Círculo Universitário
do Porto), to discuss and vote on the admission of the University of Porto and the
Instituto de Ciências do Trabalho e da Empresa — Instituto Universitário de Lisboa
as members of it and to discuss and vote on the Work Plan and Budget for 2011.
8
The Research Group Coordination Committee also met twice during 2010. On the
first meeting, held on the 19th of May, at Hotel D. Luis, Coimbra. Draft Proposal of
the 2009 Annual Report, was discussed and received a favourable opinion. The
reorganization of it Groups, a subject of growing importance since the original
group structure dates from 1993 and since then the number of it researchers has
more than tripled. The document “A policy for quality” was also discussed in order
to consider if publications in conferences should be included in the calculation of the
productivity index of it researchers. No conclusion was reached and the subject
should be discussed again. On the second meeting, held on the 6th of December, in
the Aveiro site conference room, the Work Plan and Budget for 2011, was discussed
and received a favourable opinion. Principal investigators of the internal projects
from the second call presented and discussed their achievements. The subject of
group reorganization was further discussed and the Board of Directors was
committed to put forward a proposal, taking into account all contributions, at the
next meeting of the Research Group Coordination Committee.
1.3 Highlights of 2010
Like 2009, for many reasons, 2010 was again a very good year for it apart from
funding.
Firstly, the scientific output remained high:
• 55 books and bookchapters;
• 244 papers in international refereed scientific journals;
• 15 patent requests;
• 498 papers in refereed conferences, with published proceedings.
Secondly, fostering of advanced education, although somewhat lower than in 2009
was substantial:
• 26 PhD theses, submitted and approved;
• 169 MSc theses, submitted and approved.
9
Funding for 2010 was only received in January 2011 and therefore it had to
manage with the remaining of 2009 funding, whose execution period was extended,
firstly up to the 30th of June 2010, and later to the 31st of December 2010, because
about 40% of the programmatic funding for 2009 (≈ 800 k€) was only received in
August 2010.
Finally it, together with the other two Associate Laboratories in the field of
Information and Communication Technologies (INESC-ID and INESC-Porto), was
evaluated in 2010, solely based on the information provided in FCT forms. The first
evaluation report, even if it concluded that it should continue as an Associate
Laboratory, had major factual errors, which were promptly pointed out by it.
Somewhat surprisingly, one of the four members of the evaluator panel sent (to it,
INESC-ID, INESC-Porto) his expert opinion that, in essence, contradicted the
previous evaluator panel opinion. Confronted with this rather bizarre situation FCT
has decided to order another evaluation, the results of which are not yet known.
The number of PhD students, whose scholarships are almost all funded by FCT, in
2010 was almost identical to the number in 2009. reaching an all time level. This is
an important step in improving it performance and impact.
In addition to the 224 PhD scholarships mostly funded by FCT, it hosted 19 young
students under FCT scholarships for initiating scientific activity, plus 504 BSc, MSc
and post-doc fellowships (corresponding to 378 grantees) in ongoing projects and 5
in mobility fellowships associated with the CMU-Portugal Program.
During 2010, 146 nationally funded and 35 internationally funded projects were
active, as shown in section 2.2. It is particularly noteworthy the fact that on the
31st of December it was involved in 29 FP7 projects (running and selected for
funding) in addition to other 7 projects, where there was involvement of some it
researchers from the Lisbon site.
During 2010 it continued to manage the logistics of the CMU-Portugal program by
special contract with FCT.

To reflect it 2010 activity some tangible objectives were defined in the Work
Programme and Budget for 2010. These objectives together with the achieved
values are given in Table 1

it is a member of the CIENCIA VIVA, the National Agency for Scientific and
Technological culture and co-operates in some of its events, namely those related
with the diffusion of know-how on electromagnetic radiation and its effects on the
human body. Project MONIT, (www.lx.it.pt/monit) is actively engaged in promoting
and diffusing know how on electromagnetic radiation and mobile communications.
Occasionally, through this project, it offers two week training in the measurement
of electromagnetic radiation.
In cooperation with IST, it started a one-year post graduation course in
Telecommunications and Information Technologies. Sponsored by VODAFONE and
in cooperation with IST, it organized and implemented a 30-hour update course in
Telecommunication Systems for high school teachers which was run once in 2010
(30 teachers).
Also in cooperation with IST, it organized visits and demonstrations for high school
pupils, involving about 700 pupils (in 2010).
Some of the activities mentioned in detail in Annexes are closely interconnected
with activities carried out by it researchers in the scope of their universities or
polytechnics. Their inclusion in this Report is merely for the record.

2. KEY IT INDICATORS
Human Resource
In 2010 it human resources included 875 people distributed as follows:
•
•
•
•
•
236 researchers,
224 PhD students,
378 grantees,
15 technical,
22 administrative.
All researchers but 2, hold a PhD degree.
The distribution of all human resources between the three sites is represented
graphically in Figure 2.1. It is obvious from this figure that the ratios between PhD
students and researchers and grantees and researchers is much higher in Aveiro
than in Lisbon a fact that is partly explained by the much higher involvement of
Aveiro in FP7 projects.
Figure 2.1: Distribution of it human resources between the three sites
16
The distribution of researchers and PhD students between sites and delegations is
shown in Figure 2.2. One must bear in mind that the 15 PhD students shown in
figure as belonging to the Leiria delegation, because they are all assistants of IPL,
as PhD students, they “belong to” FCTUC (14) and UA (1). This figure shows, more
than the previous one, the lower proportion of PhD students in relation to the
number of researchers in the IST site and, even more seriously, in the ISCTE
delegation.
Figure 2.2: Distribution of itresearchers and PhD students
amongmain sitesand delegations
Unfortunately our accounting systems only provides site information for grantees
and thus it is not yet possible to have a more detailed picture of grantees
distribution.
17
As a result of the application it quality policy, from the 234 researchers holding a
PhD Degree, 50 were excluded from FCT basic funding, and 12 had a 25 %
reduction of FCT basic funding. As a result in the first semester of 2011 it has
178.25 eligible researchers.
The distribution of it administrative staff is shown on Figure 2.3.

The scientific productivity in 2010 was 1.36 journal papers per eligible researcher
or, counting each book, bookchapter and journal paper as one publication, 1.67
publications per eligible researcher.
It is interesting to compare the distrubution of the number of researchers per site
and delegation with the number of number of published works (papers in
international journals and communications to refereed conferences). One should
note that the sum of the number of publications per site and/or delegation is higher
than the number of publications for it because asignificant number of publications
(about 30 %) are authored by researchers from more than one site and/or
delegation. This fact in itself is an important indicator that it is increasingly
operating as a unity rather than as a collection of research units.

Even if Figures 2.5 to 2.11 are self explanatory it is interesting to remark that at
the level of papers in journals, site distribution follows very closely research
distribution. Differences are slight at the level of communications to conferences
and considerable at the number of patents where the importance of PT Inovação

differences are rather more striking, particularly at the level of papers in journals,
which could not be seen at the site level and at communications in conferences that

4.1.3.2 Antenna analysis and design
Work on antennas followed three main streams: small antennas for indoor
applications,
antennas
for
RFID
applications
and
antennas
for
mm-wave
applications.
Small terminal antennas
Work continued on the design of UWB antennas for indoor personal communications
and for indoor localization applications. Compact slot antennas and dielectric loaded
printed monopoles have been designed and tested.
A new wideband compact slot antenna array for indoor WLAN Access Points was
developed, covering several wireless communications services from 2.4 to 4.8 GHz,
especially designed to enhance MIMO system capacity and providing both spatial
and frequency diversity. Experimental evaluation of the array performance was
performed for MIMO systems, using measured channel characterization based on a
previously developed MIMO testbed.
Small and compact multiband microstripelements and arrays have been developed
for
small
personal
multi-standard
applications.Studies
included
investigating
antenna-user interactions and the evaluation of mutual coupling and correlation.
Antenna geometries included single and multi-feed patches with slots.
Electro-textile printed slot antennas for body-implanted networks have been
designed and tested. Antenna configurations include a monopole like element and a
rectangular slot with a triangular transition on a ground plane. Improvement of
antenna radiation and efficiency have been achieved using an EBG inspired
structures.
35
RFID Antennas
Following work on this topic in previous years, work continued on reader antennas
and tags.
A passive UHF tag configuration for suitcase identification and tracking in airport
handling applications was designed using a folded dipole with orthogonal arms,
appropriate for integration into the wall of injection molded suitcases during
fabrication process.
Reader antennas for tag detection in self confined volumes covering simultaneously
all the world assigned RFID sub-bands at UHF have been designed. The proposed
configuration has been integrated with bookshelves, conveyor belt systems and
proximity point readers.
A transparent RFID reader antenna for integration into mirrors of cabinet rooms in
apparel stores has been designed and demonstrated, including the related
middleware.
New developments were achieved on UWB antennas for localization applications. A
testbed was developed to evaluate the new developed printed slot antennas and
new algorithms for indoor localization that have improved accuracy to centimeter
scale.
On the same topic, the RMOM group in Aveirohas started to evaluate alternative
antennas for indoorlocation, mainly focused on angle of arrival, where several
antennas weredesigned and are being tested. Moreover a strong effort has also
been puton reducing power consumption on the mobile tag, which is being
achievedvia improved protocols, but also via reducing power consumption.
Antennas for short range communications
New antennas weredeveloped for DSRC, Vehicular communications, among vehicles
and
betweenvehicles
communicationtechnology
and
known
infrastructures
as
dedicated
are
based
short
range
on
wireless
communications
(DSRC), which arein great development with the aim of reduce the traffic problems
and improve the road safety. One study was based on the development of asolution
36
to an antenna to be used in the mobile module, usually namedOn-Board Unit
(OBU). Another possibility was the design of an antenna forthe RSU (Road Side
Unit). In this respect Low Profile multiband Antennas for mobile communications
using Electomagnetic Band Gap (EBG) structureswere also exploited, since using
EBG structures it is possible to designantennas with low profile and simultaneously
increase the bandwidth gainand improve the radiation pattern.
Other Antennas and related work
Other lines of research have been pursued including:
•
The design of broadband integrated lens antennas for reflector antenna
illumination with constant aperture efficiency across a 1:3 frequency band
suitable for quasi-optical radio telescope systems;
•
The design of a dielectric loaded UWB monopole antenna suitable for
integration in a USB device;
•
The development of a demonstrator for a recently developed mechanically
steerable beam antenna based on a pivoting dielectric lens for 60 GHz
wireless communications and realization of preliminary tests with real video
transmission.
4.1.3.3 Integrated circuits and systems
SI based MMICs
The following circuits where fabricated and testedat microwave frequencies (2 and
5GHz) with CMOS 0.18μm technology: low noise converter for 2 and 5GHz, a class
D balanced power amplifier (1.45 GHz) and its modulated power supply (100MHz
Buck converter).
Due to the inefficiency of commercials baluns used on chip-on-board testing of the
power
amplifier,
new
testing
PCBs
are
being
developed.
Based
on
the
measurements of the low-noise converter an improved and complete dual band
receiver was designed. From the test of the Buck converter a redesigned was
37
performed. The work included redesign of analogue blocks, such as operational
amplifiers and comparators, and new design strategies to reduce bonding inductive
paths, either for QFN packages or Chip-on-Board was studied. Preliminary
conclusions indicate a performance improvement but simple PWM control technique
bandwidth was found limiting for the application in scope. Accordingly, new control
strategies are under investigation to increase the control circuit bandwidth.
An improved version of the class D power amplifier with envelope detectors and its
power supply are being designed and will be fabricated in the first half of 2011.
After a simulation study of class E power amplifier, also for 2.45 GHz (MSc thesis
concluded in 2010) using both 0.18μm and 0.13μm a prototype will be fabricated in
the same run as the class D Power amplifier (0.18μm).
From an EM study of monolithic transformers (MSc thesis concluded in 2010) we
have concluded that alternative solutions must be studied, mainly for the output
power stage. Presently, coupled lines and LC-CL combiners are being studied.
At millimetre-wave band lower edge (30GHz), the following circuits were tested: a
down-converter and active inductors implemented in 0.25μm SiGe. Based on the
test results and reverse simulations a new simple and improved version of the
active inductors, with fewer transistors and independent voltage control of
inductance and quality factor was designed and will be fabricated in the first half of
2011.
At the same frequency band but with a 0.13μm CMOS technology a Voltage
Controlled
Oscillator(32.2
GHz
to
33
GHz)
using
radio-frequency
switched
capacitors arrays and differentially tuned anti parallel varactors and a Low Noise
Amplifier were designed and tapped out for fabrication. They will be tested in the
first quarter of 2010.
The study of spiral inductors in Silicon technologies (CMOS and SiGe) continue to
be performed from 1 to 45GHz. Prototypes where tested and compared with EM
simulation with both CMOS and SiGe technologies. To improve the models
38
accuracy, a study of the technology parameters, some of them not supplied by the
foundries, and optimization of the geometrical definition of the inductors on the EM
simulators input code is being pursued.
Short range communication systems
•
A new dual RSE-DSRC (Dedicated Short Range Communication) system
was develloped, for automatic identification and toll purposes, in the
5,8GHz band, according to European standards for the physical link and
application layers (EN12834, EN12795, EN12253 and EN13372) and
compatible with the actual Via Verde System. Design, fabrication and
test of a DSRC system prototype were achieved.
•
Management DSRC 5,9GHz project (IT-Brisa). The main goal of this
project
was
the
“Development
of
Proof
of
Concept
on
wireless
communications system for road applications, with emphasis on safety,
following the WAVE recommendation”. While the standard IEEE-802.11.p
is not completed, the development will follow the IEEE 802.11.a
whenever necessary. Following the current 802.11p recommendations,
basic functionalities will be implemented in order to comply with the
identified applications and scenarios.
Software defined radio
Work was carried mainly on nonlinear distortion and Volterra series forsub-sampling
receivers. Moreover the group has devoted a certain amount oftime working on a
new vision for improved software defined radiotransceivers, in that sense several
FPGA's approaches for a all digitaltransmitter and improved dynamic range has
been also a key point of work.
Photovoltaic devices
Work has been developed for FDTDsimulation of light propagation inside a-Si:H
structures. Understanding of light transmission, reflection and propagation inside
semiconductor structures is crucial for development of photovoltaic devices. Using
FDTD
is
possible
to
simulate
the
propagation
of
electromagnetic
waves
withwavelengths in the range of the visible spectrum within a a-Si:H p-i-nstructure.
While the effects of surface reflections are easily taken into account by the
39
algorithm, light absorption represents a more criticalpoint, because of its non-linear
dependence from conductivity.
4.1.3.4 Waves and Propagation
Work in this sub-area included the characterization of propagation through
vegetation as well as research on electromagnetics of complex media with possible
applications to antennas and guided wave structures. Studies on EM exposure
assessment have also been pursued.
Radiowave propagation in vegetation media
The RMOM group has been working very actively in the study of the effects of
vegetation in radiowave propagation. New mathematical models to characterize the
effects of radiowave propagation in inhomogeneous forests at microwaves and
millimeter-waves have been devised. In addition, this research was extended to
investigate current approaches and develop new more accurate narrow and
wideband
channel
models,
and
fast
fading
models
to
characterize
signal
propagating through, around or scattered from vegetation under the effect of wind,
resorting both to theoretical investigations and experimental data gathering at 40
GHz. Some of the 2010 contributions of the RMOM group in this topic include:
•
Development of a versatile radio channel sounder prototype with the
capability
of
characterising
doubly
selective
channels
through
measurements of key channel indicators, e.g. Doppler spectra, channel
impulse response and coherence time, at 18 and 38 GHz.
•
Development and implementation of a time varying dRET simulator.
•
Enhanced formulation, test and validation of the dRET model using
deconvolution techniques to optimise its input parameter extraction
method.
• Development of an automatic antenna alignment system based on pan and
tilt positioners and inertial navigation techniques.
40
•
Extension of the dRET model to accommodate scattering from tree
trunks at 9, 18 and 38 GHz.
•
Development
of
a
measurement
system
that
enables
DVB-T
measurement trials, both at radio and link levels in addition to video and
channel coding optimizations.
•
Development of a fleet management system to remotely acquire data
from digital tachographs.
Earth-Satellite propagation
On the framework of Earth-Satellite propagation a beacon receiver wasoperated
successfully logging one additional year to the propagationdatabase. The database
now comprises 6 years. A beacon receiver based onGNU-Radio was developed and
results published in a conference paper. Theexperimental database was studied
concerning aspects of the parameters attenuation, depolarization and rain rate. The
hourly, monthly, seasonallyand yearly variability was and his being studied. The
long distance rainand attenuation correlation that is very important for diversity
wasstudied in a collaboration framework with Madrid (UPM) giving a paper in
ajournal and presentation at COST IC-0802. In the framework of the COST-IC0802
some preliminary study of abovevariability was made by comparing data from
Madrid (UPM) and Otawa-Canada(CRL).
Propagation channel for mobile communications
In the framework of the propagation channel for mobilecommunications the Sage
algorithm
for
directional
channel
characterizationwas
optimized
with
an
implementation in the frequency domain and otherprocedures for an intelligent
search starting options. Algorithms forclustering techniques were implemented and
critically compared in real andsynthetic channel environments.
Electromagnetics of Complex Media
In the last year work has been done on homogenization and characterization of
structured structures. Characterization of novel nonlocal metamaterials, with
anomalous
properties,
such
as
lossless
broadband
anomalousdispersion
or
broadband negative refraction has been pursued.The development of different wire
media prototypes that exhibit extreme permittivity values over broad frequency
41
bands has been achieved and demonstration of their use for superlenses has been
performed. A more detailed description follows:
•
Homogenization and applications of metamaterials with anomalous
dispersion. One of the key challenges in metamaterial theory is to reduce
the inherent complexity of the microstructure to a few effective
parameters, usually an equivalent permittivity and permeability, making
an otherwise very intricate problem easily accessible to theoretical
modelling. Such an approach is physically sound when the wavelength of
the radiation is much longer than the characteristic features of the
metamaterial, so that the intrinsic granularity of the system can be
neglected, and the structure can be regarded as a continuous effective
medium. The homogenization approach is especially tricky in case of
spatially dispersive materials, such that the macroscopic polarization
does not respond locally to the electric field. One of the contributions of
the RMOM group was the development of the theory of spatially
dispersive metamaterials based on arrays of nanowires. In particular, we
have investigated the electrodynamics of novel nonlocal metamaterials
with low loss broadband anomalous dispersion. We demonstrated that
such materials can be useful to correct the chromatic aberrations of
optical systems, compensating for the normal dispersion of dielectrics.
•
Casimir interaction in metamaterials. The illusive Casimir effect is one of
the most intriguing physical phenomena, which, due to the quantum
fluctuations of the electromagnetic field, results in the attraction or
repulsion of uncharged bodies. This tiny force is only relevant in the
nanoscale, since it invariably decays with the fourth power of the
distance between the bodies. However, in 2010 the RMOM group has
shown how by guiding the quantum fluctuations of the electromagnetic
field with an array of metallic nanorods it is possible to boost the
strength
of
the
Casimir
force
by
several
orders
of
magnitude.
Furthermore, it was demonstrated how this ultra-long range force can be
put into work and used to levitate objects! It is envisioned that these
42
findings may have interesting applications in the realization of novel
materials with improved adhesive properties (a “quantum”-super-glue).
•
Detection of targets separated by subwavelength distances based on a
metamaterial with extreme parameters operated in a backscattering
mode. One of the holy grails in the metamaterial field has been since the
beginning the possibility of imaging not limited by diffraction. This is a
quite challenging problem, and a successful approach to superlensing has
to overcome many barriers. In 2010, the RMOM group has proposed and
demonstrated
experimentally
a
novel
broadband
approach
to
superlensing based on a metamaterial with extreme parameters. It was
shown that this novel solution enables discriminating objects separated
by tiny distances on the scale of the wavelength. It is expected that such
results may have applications in sensing and RFID.
•
Development and demonstration of a novel minimally invasive system
based on a metamaterial lens to measure the near-field of an antenna.
Measuring the near-field has important applications, such as the
calculation of the radiation pattern of large aperture antennas. However,
the
realization
of
near-field
probes
for
all
components
of
the
electromagnetic field may be quite challenging, particularly if one is
interested in measuring both amplitude and phase. Moreover, the
measurement of different components of the field typically may involve
the use of different probes, which may interact with the antenna under
study in the different manner, resulting in the inaccurate determination
of the near-field. In 2010 the RMOM group proposed and demonstrated
experimentally a metamaterial inspired near-field lens that enables the
characterization of the near-field field of an antenna in a minimally
invasive manner.
•
Ultrasubwavelengthwaveguiding. Confining and guiding electromagnetic
radiation in volumes with dimensions far beyond the diffraction limit can
have important applications in emerging nanotechnologies. A popular
approach
to
subwavelengthwaveguiding
is
based
on
surface
43
plasmonpolaritons (SPPs) supported by metal-dielectric interfaces. This is
viable at optical frequencies where the dielectric constant of metals is
predominantly real and negative. At lower frequencies, metals begin
resembling perfect electric conductors, leading to weakly bounded SPPs.
In 2010 the RMOM group has proposed a solution to this problem, and
demonstrated that strongly coupled grids of metallic nanorods, resulting
from the hybridization of weakly bounded plasmons, enable wide band
low loss ultra-subwavelengthwaveguiding, which may determine a new
paradigm for light confinement and waveguiding in the nanoscale.
Fundamental work on electromagnetic wave propagation in complex media (namely
chiral, anisotropic and bi-anisotropic media) has been continued both for
unbounded media and in the presence of interfaces (reflection and transmission
characteristics). Applications of the Clifford (geometric) algebra of the (ordinary)
three-dimensional space to the analysis of anisotropic media characterized by both
electric and magnetic anisotropic functions as well as applications of spacetime
algebra, the Clifford algebra of Minkowskispacetime, to relativistic optics of moving
media have been studied. The main results of this work include:
•
A new classification scheme for anisotropic media based on the overall
behavior of the medium, rather than on the permittivity and permeability
functions separately considered;
•
A new perspective on moving media, that simplifies and brings new
physical
and
geometrical
insight
as
compared
to

Work on guided wave structures with chiral media has been continued and
propagation characteristics of chiral H-guides have been studied. A new line of
research has been open on indefinite media, i.e., media with simultaneous positive
and negative parameters. Several uncommon properties as coexistence of forward

4.1.3.5 Radio Networks
Within eMobility project, contributions to the Strategic Research Agenda and to the
Strategic Applications Agenda were given.
Major results in this topic include:
• The development of channel models for Body Area Networks;
• The continuing development of CRRM algorithms for heterogeneous mobile
communication systems;
• The development of RRM algorithms for virtual communication systems;
•
The development of various simulators for the air interface of UMTS-FDD,
with HSDPA and HSUPA, and LTE, enabling analysis of traffic aspects as
well as load and handover ones.
4.1.3.6 Transmitting and Receiving Systems
These studies were mainly concentrated in the optimization and performance of
current and next generation radio systems, both for mobile communications (such
as Wimax, LTE and LTE-Advanced) and satellite systems, with special emphasis on
radio navigations systems.
Mobile communications
The achievements for mobile communications in 2010 focused on several aspects of
present and future radio systems, such as network planning, air interface and
capacity enhancements, and channel estimation.
Following the work of previous years, studies were performed to coordinate the
interference for E-MBMS transmissions in LTE-Advanced systems, figuring out some
power saving techniques. Capacity enhancements for wireless communications
systems using multiuser MIMO techniques, namely for LTE in macrocell scenarios,
were also studied.
Networking aspects were also addressed, namely radio network planning for the
next generation cellular networks, the study of centralized cooperative spectrum
sensing for ad-hoc disaster relief networks and also with iterative multipacket
45
detection for high throughput transmissions in OFDM Systems. WIMAX and Wi-Fi
networks were also planned and deployed regarding Health Sciences Education and
applications such as wearable sensors for foetal movement monitoring in low risk
pregnancies.
The air interface of radio systems was also studied in several aspects including
modulation, coding, equalization, channel estimation and synchronization. Most of
these studies were based on an analytical approach. For example, the analytical
evaluation of nonlinear effects on OFDMA signals or an analytical approach to
evaluate the performance of a class of receivers with joint equalization and carrier
frequency synchronization. Other studies focused on nonlinear frequency domain
equalization with single carrier modulation.
Some studies were closely related to modulation. For example the analytical
matched filter bound for M-QAM hierarchical constellations with diversity reception
in
multipath
Rayleigh
fading
channels
and
an
iterative
frequency
domain
equalization and carrier synchronization for multi-resolution constellations.
Other new research aspects with interesting results include a new analytical model
to evaluate the correlation of spreading sequences when submitted to a nonlinear
system, using the family of OQPSK signals. This allowed us to determine and
compare the properties andbehaviour of different types of sequences (such as Gold,
maximal length and TCH) when submitted to a real nonlinear system. Using this
approach, new results and studies can now be obtained to improve important
aspects of receivers such a synchronization or channel estimation.
Satellite systems were also a subject of research in many aspects. A new technique
based on Magnitude Modulation has been devised to reduce the back-off in satellite
transmissions using digital signal processing techniques to implement polyphase
filtering nagnitude modulation. This technique can now be used for QAM
modulations to efficiently reduce the power requirements in this type of systems.
The existing satellite earth station at the Instituto de Telecomunicações was also
improved with the implementation of a dedicated server for remote operation and
control.

GNSS Solutions
There were several studies focused on GNSS solutions, including the development
of a GPS based coordinated positioning system, the implementation of a GPS
monitoring station data management and WAW location-based service Positioning.

Title
ADCOD
Advanced Code and Receiver Designs for Transmission over Selective
Radio C
Funding
FCT/PTDC
Descript.
Future wireless systems are expected to support data rates of several
hundreds of Mbit/s in a variety of scenarios with high spectral and
power efficiencies. Due to high transmission rates the channel will be
severely
time
dispersive.
For
this
reason,
block
transmission
techniques combined with frequency-domain equalization (such as,
OFDM (Orthogonal Frequency Division Multiplexing) and SC-FDE
(Single-Carrier Frequency-Domain Equalization) modulations schemes
are strongly recommendable.
A key technology to improve power and spectral efficiencies is the use
of multi-antenna schemes exploiting spatial diversity (such as STF
(Space-Time-Frequency) codes) and spatial multiplexing (such as LST
(Layered Space-Time) techniques). The use of signals with reduced
envelope fluctuations is also important to allow efficient power
amplification. This is particularly important in the case of OFDM
signals. Conventional FDE implementations require accurate channel
estimates at the receiver, something particularly important in multiantennas systems. These estimates can be obtained with the help of
appropriate training symbols or blocks. Due to frequency offsets and
Doppler effects, the channel is expected to change from block to
block, or even within a given block, especially for large blocks, high
carrier frequencies and/or high moving speeds. In this case, it might
be recommendable to employ non-coherent systems. This project
considers
efficient
transmission
schemes
for
frequency-selective
channels. For this reason, we will employ OFDM and SC-FDE block
transmission formats with multi-antenna schemes. The research team
involved in this project includes researchers working in transmission,
49
codebook and receiver design and optimization, as well as researchers
working on propagation issues. In the first phase of this project, we
address the problem of STF codebook design for both coherent and
non-coherent
communications.
In
contrast
with
conventional
approaches, the codebook design takes into account the envelope
fluctuations and dynamic range of the transmitted signals, so as to
allow efficient power amplification. We will also take into account nonlinear effects (e.g., due to clipping of OFDM signals) in the STF code
design. The impact of nonlinear distortion effects on the designed STF
codes will be studied, whenever possible, employing analytical
methods. Contrarily to the usual approach, we will take into account
non-white noise effects (e.g., due to self-distortion inherent to
nonlinear effects) in our designs. Pragmatic code designs (eventually
combined with conventional error correction schemes and allowing
low-complexity transmitter/receiver implementations) will also be
considered.
In the second phase of this project, we will generalize the results
obtained in the first phase to the fading channels that are both timedispersive and time varying (i.e., doubly selective channels). For the
coherent case, the combination of suitable block/frame designs and
adequate estimation and tracking techniques (both for the channel
frequency response and the frequency offsets/phase noise carrier) will
be considered to cope with time-varying channels. We will also
develop receiver structures for the case where the channel changes
significantly within a given block, both coherent and non-coherent.
To achieve these goals, we need accurate channel models taking into
account short-term and long-term variations. We will develop new,
more
accurate
narrow
and
wideband
channel
models
through
theoretical investigations as well as experimental data gathering for
different frequencies (e.g., 2.4, 5.6 and 38 GHz), in several
deployment scenarios. A time-varying tapped delay line based model
will
be
developed
to
represent
the
doubly
selective
channel
phenomena. The combined channel model will be suitable for
simulating fading mitigation techniques such as adaptive coding and
50
modulation, interference cancellation, and other capacity enhancing
techniques. We will also consider STF codebook designs and receiver
designs exploiting the knowledge about short and long term channel
statistics.

C2POWER
Cognitive radio and Cooperative strategies for POWER saving in multistandard wireless devices
Funding
EU, FP7
Descript.
The promise of a truly mobile experience is to have the freedom to
roam around anywhere and not be bound to a single location.
However, the energy required to keep mobile devices connected to the
network over extended periods of time quickly dissipates. In fact, the
operational time, has been identified as the number one criteria by the
majority of the consumers purchasing a mobile device. Moreover,
concern about exhausting battery lifetime is also one of the main
reasons why users do not opt to use advanced multimedia services on
their mobiles more frequently.
To avoid the foreseen 4G “energy trap” C2POWER project will
52
investigate, develop and demonstrate how cognition and cooperative
strategies
can
be
extended
to
decrease
the
overall
energy
consumption of mobile devices while still enabling the required
performance in terms of QoS.
In particular, C2POWER will investigate two complementary techniques
to increase power efficiency at the wireless interface of handsets:
•
Cooperative power saving strategies between neighbouring
nodes using low power short range communications;
•
Cognitive handover mechanisms to select the Radio Access
Technology

Title
Cooperative and Antenna Diversity for Broadband Wireless Networks
Funding
FCT/PTDC
Descript.
Wireless services are of great economic and social value and will be one
of the enablers of the so-called information society. It is envisioned that
among the multiple networks/services that will be part of what is
commonly termed as 4G, we will have a broadband component, where
spectrum
efficiency
will
be
a
premium.
This
means
that
the
terminals/access points will need to explore in a “quasi-optimal” way all
the dimensions provided by the space/time and frequency domains of
the radio channels. Diversity is inherent and well known in the physical
layer and either time, frequency, space has been used to combat the
fading by trying to stabilize the channel. Diversity can also be achieved
in the MAC or higher layer, which is termed network diversity, which can
be divided in multiuser diversity (by scheduling or routing) and
cooperative diversity (by cooperative transmission). While research
concerning the classical forms of diversity has already taken a very
practical flavour with proposals/technological evaluation and integration,
53
the know-how to exploit the benefits brought by the cooperative
dimension is still far behind and also the understanding of the impact it
may have on wireless network planning. These provided the main
impetus
for
this
project
proposal
whose
key
objectives
are:
Definition, evaluation and validation of techniques exploiting channels
diversity and cooperation between users in order to enable the high bit
rates targeted in the broadband component of future wireless systems;
improve the power and spectrum efficiencies of the existing OFDMbased wireless systems and improving and/or extending coverage and
fairness. Most of the research work in this area have assumed dedicated
relays (fixed or nomadic), while the CADWIN project will also consider
relaying functionalities at the MT. To reach these main goals, specific
research objectives are:
• Design and evaluation of practical VMIMO or distributed coding
algorithms. In a first phase we will start with space-time/frequency
block codes designed for co-located antennas, which will be evaluated in
a distributed environment. In a second phase, specific and optimized
solutions will be proposed and investigated.
• Design and evaluation of practical distributed precoding algorithms
considering different levels of the channel state information available at
the transmitter (BS in the downlink), relay and destination (MT in the
Downlink). Precoding algorithms to enable cooperation between base
stations to provide intercell interference cancellation will also be
considered.
• Design and evaluation of joint distributed precoding and spacefrequency/time coding algorithms. In a first phase the concepts of
distributed precoding and coding are considered separately, while in a
second phase the researchers working on the two topics will consider
the optimized joint precoding/coding schemes.
• Design and evaluation of channel estimation algorithms. In a first
phase we will evaluate the classical channel estimation algorithms in
cooperative communications scenario with emphasis on AF relaying
protocol. In a second phase, will investigate and evaluate specific
algorithms to deal with the issue of estimating non point-to-point
54
channels, present in the envisioned scenarios.
• Design and optimization of medium access control protocols for
centralized and decentralized systems with joint scheduling, relay node
selection and dynamic link adaptation.
• Study
and
design
of
systems
with
imperfect
network
station
information and evaluation of signalling resources for setting up
cooperative relaying schemes.
• Development of a system level simulation tool for analysis of a hybrid
cellular network incorporating cooperative diversity.
• Usage of the simulation tool to validate the algorithms developed and
demonstrate at a system level the potential of cooperative diversity.

COGEU
Cognitive radio systems for efficient sharing of TV white spaces in
EUropean context
Funding
EU, FP7
Descript.
The complete transition from analogue to the digital TV is planned in
Europe for 2012. This will release significant amount of valuable
spectrum in VHF/UHF bands. In fact, the Digital TV Switchover provides
a “once in a lifetime” opportunity for the development of innovative
services and the introduction sophisticated new technologies into the
VHF/UHF bands.
However, despite the grand words about opening up a new band to
support low cost, low power, ubiquitous access and innovative new
providers, there are many obstacles to TV white spaces systems. The
creation of workable devices that clearly demonstrate and prove that
no harmful interference is caused to broadcasters or other licensed
systems is one of those challenges as is the completion of standards.
The CogEU project aims to take advantage of the transition to digital TV
by developing cognitive radio systems that leverage the favourable
propagation characteristics of the TVWS through the introduction and
55
promotion of real-time secondary spectrum trading and the creation of
new spectrum commons in the upper band of the cleared spectrum.
CogEU will also define new methodologies for TVWS equipment
certification and compliance addressing coexistence with the DVB-T/H
European standard.
Three main application scenarios with good market potential will be
investigated:
•
Cellular, WiFi and WiMax network extension over TV white spaces
•
Mobile TV over TV white spaces
•
Public safety applications over TVWS

Title
Coordinated Multiuser MIMO for Future Wireless Networks
Funding
FCT/PTDC
Descript.
The aim of the project is to provide a better understanding of multiuser
coordinated
multiple-input-multiple-output
(MIMO)
capacity
enhancement in the fourth (and future) generation(s) of wireless
systems. In fact, the realistic capacity estimation using spatial
multiplexing and beamforming MIMO is of great interest, since it
represents the enabling technology to achieve the new 4G 5 bit/s/Hz
spectral efficiency requirement.
MIMO links can offer a so called spatial multiplexing gain by opening
parallel spatial data pipes or channels within the same frequency band.
This is achieved by the creation of orthogonal information channels
mostly
in
the
presence
of
rich
multipath
leading
to
antenna
decorrelation.
In these conditions, MIMO links offer capacity gains (relatively to SISO)
that are proportional to the minimum of either the number of TX and
RX antennas. As a matter of fact, a key feature of MIMO is to turn
multipath propagation, traditionally a pitfall of wireless systems into a
benefit for the user. MIMO takes advantage of random fading, for
56
increasing transfer rates.
The proposed work in the project will cross the fields of research of
mobility and channel modeling, information theory and practical
systems and applications. Firstly, directional channel modeling will be
developed in order to simulate the MIMO channel.
Secondly, information theory and eigenanalysis based on MIMO spatial
multiplexing and beamforming will be used, together with the use of
uniform and power efficient allocation methods. Optimized MIMO
antenna configurations will be set, in order to boost up cell capacity.
Then, the gains of using coordination methods in multiuser scenarios
will be considered with applications examples and system performance
evaluations over LTE (and LTE Advanced) and mobile WiMAX 802.16
family of standards radio interfaces.
This evaluation will be done considering radio advanced resource
management techniques such as improved admission control, power
control and scheduling techniques.

Multi-Packet Detection Techniques for Satellite Networks
Funding
FCT/PTDC
63
Descript.
Future satellite communications systems face a challenge to provide
higher bitrates, together with improved QoS (quality of service)
guarantees, to more GT (ground terminals). Moreover, this should be
achieved with higher spectral and power efficiencies, with less energy.
This project considers future very high bitrate LEO (Low Earth Orbit)
satellite systems with satellite MPR (multipacket reception), compatible
with low-cost portable GTs. A cross-layered approach is proposed: a
physical layer team will handle the signal design, the synchronization
and
estimation
issues,
and
the
receiver
design,
including
MPR
development; a data link layer team will handle the Multiple Access
control protocol design and the scheduling algorithm to support
different QoS (Quality of Service) classes, and the interaction with the
network layers. Both teams will be involved in the design and test of
the cross-layering features involving both layers, required to provide
guaranteed QoS, even during satellite handover.
In this project we will develop OQPSK-type schemes with reduced
envelope fluctuations and high power and spectral efficiencies and
compatible with an efficient and low cost power amplification. To
further improve the overall system power efficiency we also consider
schemes
with
spectral
overlapping
between
different
frequency
channels. With respect to the receiver design, the main goal is an
efficient multipacket detection technique able to cope with collisions,
already shown by the research team to allow significant improvements
in personal area networks. We will consider turbo frequency-domain
equalizers suitable to cope with time-dispersion effects and able to
handle spectral overlapping between frequency channels. Hybrid
ARQ/FEC (Automatic Repeat reQuest/Forward Error Correction), namely
with packet combining, will be proposed to handle fading for the most
demanding QoS classes and control packets. To cope with Doppler
effects, suitable synchronization and channel estimation methods will
be developed for MPR on a LEO scenario. Joint detection and estimation
schemes will be considered. Since MPR needs to know which users are
involved in a collision, suitable methods to detect them will be
developed. The statistical characterization of block error rates with MPR
64
will be evaluated using simulations for homogenous and heterogeneous
SNR GTs. We will develop a new MAC protocols for MPR that combine
random access with demand assigned access on the uplink controlled
by a downlink control channel, offering improved QoS support
compared to other LEO MAC protocols.

access technologies, complemented by a business exploitation strategy
that adapts to future economic infrastructures.
Advanced algorithms for multi-band access/selection will be explored to
optimize the offered capacity whilst maintaining the user service
experience acceptable. Also secondary users may have temporary
opportunistic access to free spectrum ''holes'' or a set of users may
simultaneously utilize, optionally, spectrum resources in lower/upper
frequency
bands,
improving
the
quality
of
experience.
The
consequences of this new perspective for spectrum management in
public policies will be addressed as well as the impact of having
secondary spectrum markets. From the technical point of view,
modeling, simulation and experimental approaches will be followed,
e.g., by using emulators with a hardware component within academic
and/or industrial partnerships to be developed. Spectrum usage
optimization is one of the goals of our Project, fig. in Annex. The
opportunistic utilization of spectrum holes by secondary users will be
investigated by implementing novel MAC designs regarding sensing
cooperation and opportunistic transmission that will use cross layer and
cross system information. Another objective is to attend to the
increasing demand of higher data rates. Spectrum aggregation (SA) is
a technique that attempts to increase spectrum utilization and it is
therefore a coming solution to support the 100 MB/S over a wireless
connection.
After
World
Radiocommunication
Conference
2007
(WRC07) the new bands to be considered for International Mobile
Telecommunications - Advanced (IMT-Advanced) were 450-470, 698862, 790-862, 2300-2400, 3400-4200 and 4400-4990 MHz. In order to
support the increasing demand of high data rates bandwidths of
100MHz have to be considered. These bandwidths can only be achieved
67
by going to high frequencies.
The drawback of going into high frequencies is the high propagation
losses and the Doppler Effect on high velocities. Multi-hop and
Infrastructural users will be managed by a Multiband Common Radio
Resource Management (MB-CRRM) entity. This management will be
direct in the Infrastructural case scheduling user/group of users in a
given frequency and indirect in the multi-hop case (secondary users) by
demanding or leaving a control channels open for secondary user
coordination and taxation. The management of secondary users will be
performed by making hopping frequency directives so that a dynamic
coordinated
secondary
use
of
the
spectrum
can
be
made.
The MB-CRRM has the ability to optimize frequency scheduling for
infrastructural users, and also frequency scheduling for secondary
usage. While each system maintains control over his RRM entity,
including the distributed secondary system, the MB-CRRM entity will
make them more dynamic radio wise.
A wide and local MB-CRRM optimization could be differentiated. By wide
MB-CRRM it is meant frequency planning for all the systems being
considered in a given area considering several base stations (BSs).

FCT/PTDC
Descript.
This
project
is
aimed
at
the
design
and
test
of
an
innovative RF Self-Oscillating Power Amplifier (SOPA) in which the
feedback loop is not made at the RF carrier, as in the usual approach,
but now between the output signal envelope and the input baseband
signal. This topology is a novel, and very promising, approach to the
linearity/efficiency compromise in RF transmitters as it is capable of
greatly
reducing
switching
losses
but
also
compensate
for
the
nonlinearities of the AM and PM modulator, of the RF PA and of the
output band-pass reconstruction filter. Furthermore, the complex
stability and ultimate injection locked behavior analysis of these SOPA
structures (which is a determinant problem for any highly nonlinear
dynamic
feedback
bifurcation
loop)
analysis
will
be
across
thoroughly
input
performed
envelope
through
amplitude.
In addition, this new SOPA based Tx architecture, but also many other
coming digital Tx’s, suffer from the inexistence of proper simulation
tools. As they involve baseband AM and PM signals, a digital selfoscillating clock and a RF carrier - of three disparate time-scales exciting strongly nonlinear low-frequency broadband but also RF
narrow-band circuits, no circuit simulation tool is able to handle it. So
state-of-the-art simulation techniques for systems with autonomous
components
(as
is
the
case
of
SOPAs)
will
be
studied.
In summary, the expected results from this project are: (i) systemlevel analysis of SOPA behavior, its stability and injection locking
conditions; (ii) the design, implementation, test and validation of a
novel, highly efficient and linear, SOPA based Tx topology; and (iii) a
74
new simulation method dedicated to device-level simulation of SOPA
circuits (or circuits that suffer from similar multirate problems).

Title
TACCS - Cognitive Radios Adaptable Wireless Transceivers
Funding
FCT/PTDC
Descript.
Software Defined Radio has already start its way to conquer traditional
radio
configurations,
by
moving
base
band
(de)modulators
completely to the digital world and thus implementing it by software.
Nevertheless, it is expected that Cognitive Radio, CR, will be the next
frontier in terms of radio architecture design, in fact the new
paradigm that CR can bring to traditional ways to think on radio
architectures, is so huge, as it was the transition from Analog to
Digital systems.
CR will allow the optimization of radio spectra occupancy, but also the
implementation
of
the
supreme
universal
radio,
that
is
radios
that talk to each other’s no matter the original implementation.
But in order to achieve such a new deployment, the radio should be
constructed with some form of processing capabilities, which it is
not possible with traditional schemes, that processing capabilities arises
from some kind of processor that treats the transmitted/received signal
in real time, and makes decisions over it.
That
processing
capabilities
should
be
done
at
the
digital
counterpart, but also, and most of the time neglected, at the analog
part. In fact the main conclusion of the last SDR forum meeting
was that the analog part, usually called agile radios, should have a
huge
research
effort
in
order
to
implement
most
of
the
CR
concepts.
This project aims exactly to study most of the physical layers of CR,
starting from agile RF front ends, but also considering digital
implementations,
either
FPGA
based,
but
also
DSP
75
based.
The project will try to give an answer to software engineers, by
carefully studying the last piece of the system that is avoiding the
complete implementation of CR. The main difficulty of implementing
these CR architectures is the non-ideal behavior of the analog
components, due mainly to bandwidth limitations, and to signal
amplitude limitations, dynamic range, by creating nonlinear distortion
that severely degrades SNR. Thus the correct identification of the
system components behavior, that is nonlinear dynamic models, the
correct understanding of the new waveform behaviors, which will be
created in the CR approaches, will allow the correct design of the
transmitted signal. This signal should be pre-distorted in order to be
transmitted with perfect spectrum masks, but the received signal
should also be compensated either by overcoming the non-idealities of
the receiver components but also by reducing interference distortion
due to the existence of jammers outside the band. Thus the now
proposed work will make new contributions on (1) behavior models for
non-ideal analog RF components; (2) new signal identification methods,
either for evaluation of the analog needs at transmission or at
receivers, but also for spectrum sensing; (3) new waveform generation
for CR applications, in order to maximize the SNR, but also for
maximize the transmitted bit rate; (4) new design of reconfigurable
architectures based on FPGA, for efficient CR implementation; (5)
improved receivers for spectrum sensing sub-systems by maximizing
the gathering of large bandwidths; (6) new improved receivers for
maximization of dynamic range; and finally (7) new transmitters for
linear and high efficient signal communications.
The
proponent
team
is
composed
of
a
number
of
different
knowledgeable elements, coordinated by a senior researcher of IT with
previous international and recognized work on nonlinear distortion
modelling,
RF
circuit/system

4.2.3.2 Optical Components and Subsystems
The work carried out in this sub-area concentrated on the modeling, performance
evaluation, optimization and implementation of key components and subsystems
for all-optical networks.
The transfer matrix method (TMM) has been extended for the dynamic analysis of
non-conventional DFB laser structures (dynamic TMM). The transient response
(emitted power) and the variation of the lasing wavelength with time for MPS-DFB
structures, when the biasing current (modulation depths) is a step-function, have
been analysed.
The study of frequency response of semiconductor PIN photodiodes for optical
communications continued. The numerical model for the frequency response was
generalized by including the capacitive effects which are known to play an
important role in the frequency response of short devices. A detailed analysis of the
effect of the length of the absorption region, the area and series resistance of the
device and the bias voltage on the bandwidth was undertaken. In order to
overcome the limitations imposed by the capacitive effects to the bandwidth of the
device, some novel structures were investigated namely of the type PIIN where the
added intrinsic region is of the same semiconductor material as the N and P
regions. Some preliminary results show that these optimized structures have larger
bandwidths than the conventional PIN structure.
An analytical model accurately describing the evolution of the relative state of
polarization between two signals in high-birefringence fibers was developed. It was
shown that for small fiber lengths or narrow wavelength separation, launching two
signals with orthogonal polarizations can present a higher degree of co-polarization
along the propagation. The model was experimentally validated by comparing
118
theoretical and experimental four-wave mixing results in a dispersion shifted highbirefringence fiber.
The influence of the stimulated Raman scattering in the four-wave mixing process
in high birefringent fibers was theoretically analyzed. Results show that when the
phase-matching condition is satisfied the optical power evolution of the signal and
idler waves for small frequency detuning are mostly described by the anisotropic
Raman response of the fiber, whereas for high frequency detuning the isotropic
response dominates. Our analysis also shows that the stimulated Raman scattering
can increase the efficiency of the four-wave mixing process, for certain frequency
detuning.
A new method to measure the effective nonlinear parameter of a fiber was
developed. The effective nonlinear parameter was experimentally measured and the
transition region between an almost co-polarized to a de-correlated state of
polarization was observed. The method was experimentally validated by comparing
theoretical and experimental four-wave mixing results in a low power regime.
In the area of optical amplification, a new method to mitigate the transient effect in
optical fiber Raman amplifiers was developed. This method is based on a pumpcontrolled gain-locked system and is suitable to be used in pump-reflecting Raman
fiber amplifiers. Using this approach, an efficient low-cost Raman fiber amplifier
suitable for dynamic optical networks was obtained. The developed method was
subject to a patent registry.
Optical amplification in the visible spectral region for plastic optical fiber
applications
was
also
studied
theoretically
and
experimentally.
Reflective
semiconductor optical amplifiers have been characterized under RF modulation, in
order to optimize its parameters for radio over fiber applications.
Work has also been carried out in the area of production and characterization of
components in integrated optics. Mach-Zehnder and Y-branch splitter, based on
sol-gel technologies, have been developed for passive optical networks.
In the area of all optical processing for high bit rate optical networks, advanced
techniques for all-optical routing, tunable dispersion compensation, optical filtering,
pulse shaping, clock recovery, optical code division multiplexing and regeneration
were developed.
119
An acoustic wave generator for optical fibers to be used in tunable filters was
designed and implemented.
Research work on all optical signal processing with semiconductor optical amplifiers
started, and a lab experiment has been designed for evaluating new applications,
namely static RAM.
Work in the area of optical sensors included: the development and optimization of a
fiber monitoring system, based on fiber sensors and wireless transmission; novel
plastic fiber sensors for refractive index and bending measurement; a novel sensor
for simultaneous refractive index, temperature and stress measurement based on a
tilted fiber Bragg grating; and a novel sensor for simultaneous measurement of
temperature and deformation based on a tapered fiber. These sensors were tested
in civil engineering infrastructures as metallic bridges, metallic telecommunication
towers and concrete structures
The work on all optical signal processing with SOAs has been focused on the set-up
of a lab experiment for evaluation of static RAM. A new proposal for implementation
of static RAM has been presented.
4.2.3.3 Optical Communication Systems
Advanced modulation formats for optical fiber communication systems were
investigated. A novel semi-analytical method for BER evaluation in simulated optical
DQPSK systems was developed, and an accurate method of performance
assessment for DQPSK systems in presence of receiver imperfections was
proposed. Pseudo-linear transmission regime with high-speed optical singlesideband (OSSB) signals and electrical dispersion compensation was investigated.
An analytical method to estimate the degradation of signal quality in case of OSSB
signals with different modulation formats was investigated.
In the area of radio over fiber (RoF) systems, optical filters were developed and
optimized for these systems. Performance of BPSK vs QPSK for optical distribution
of orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB) radio
signals in fiber-to-the-home (FTTH) networks was compared. The state-of-the-art
of joint optical/radio OFDM transmission impairment compensation was identified.
Research on 60 GHz MMW band focused on photonic techniques for generation of
MMW sub-carriers has begun during this reporting period. Transmission of 802.11g
signals over a 10Km RoF link was demonstrated.
120
The Ph-ADC photonic structure based on TDM was optimized and the impact of nonlinear fibre impairments on the Ph-ADC performance was assessed. The feasibility
of the structure for photonic analog-to-digital conversion (Ph-ADC) based on
wavelength division multiplexing was investigated in the UCELLS project. Its
performance was compared with the performance of the Ph-ADC photonic structure
based on TDM.
Numerical and experimental investigation concerning the transmission of multiband OFDM-UWB radio signals along distances typical of next generation fibre-tothe-home (NG-FTTH) networks, using directly modulated lasers (DML) and
externally modulated (EM) transmitters has been performed. The investigation of
optical-wireless convergence in NG-FTTH networks was started. Preliminary
numerical and experimental work concerning the transmission of coexisting OFDM
signals using DML and EM as optical transmitter has been performed. Research
work on the linearization of direct-modulated lasers for application in the
transmission of different wireless standardized signals through optical fiber has
been initiated.
Optical transmission systems based on mode group diversity have been identified
as having a large potential. A digital simulator of the propagation in multimode
fibers is under development which takes into account modal coupling at fiber
imperfections and splices between monomode and multimode fibers. A nonlinear
model for pulse propagation in multimode fibers with reduced radius, which support
a small number of modes, is also under development. The transmission of multiband orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB)
radio signals along multimode fibre was investigated. The main transmission
impairments were identified.
Research on RoF systems in the framework of project RoFnet (FCT) has been
directed to the MW and MMW bands, and was focused on photonic techniques for
generation of MW and MMW sub-carriers. New proposals for simultaneous transport
of different services in the baseband and in several microwave and millimeter wave
bands, and about the optimum operating conditions for supporting multiple radio
channels over a SCM-based distributed antenna system.
A rigorous method (based on the moment generating function) to assess the
performance of the transmission of OFDM signals with direct-detection optically
preamplified receivers has been started.
121
4.2.3.4 Optical Networking
The work on access networks has continued, focused on next generation PONs and
their convergence/integration with MANs.
In the area of FTTH, there have been some main achievements which some
resulted in 2 national patents and one international patent in the field of OTDR for
PON
and
remote
powering
of
amplifiers.
This
aligns
with
several
other
achievements in the design of other specific blocks for NGPONs, like amplification
schemes to extend the GPON operation range. These amplification schemes were
implemented using EDFA, SOAs and Raman amplifiers with the appropriate
transients mitigation schemes.
The search for new CDMA codes has been pursued, by exploring their applicability
in access networks with coherent modulation and detection.
Work on optical burst-switched networks continued in 2010. A framework for
routing path optimization by using an ant colony optimization technique was
developed and its performance was evaluated by network simulation. A strategy for
optimizing the structure of an OBS burst-switch by using wavelength contention
minimization algorithms was proposed. The use of Raman amplification in optical
burst switched networks was analyzed and compared (experimentally and by
simulation) with other amplification technologies (EDFAs and SOA).
Work on optical burst-switched networks continued in 2010. Strategies to deal with
quality-of-service differentiation in OBS networks have been developed.
In the packet networks area, an all-optical packet monitoring technique was derived
and is being simulated and started its path to experimental demonstration in order
to give to the physical layer some more abilities and capabilities.
In the all-optical processing, some efforts we have been made in deriving some
latching structures and with that aiming the all-optical memories. A set of schemes
were observed and proposed.
An optimization framework for designing OTNs in environments with mixed line rate
demands (40 Gb/s e 100 Gb/s), aiming the minimization of the network cost, by
taking
into
account
aspects
such
as
grooming,
virtual
concatenation
and
regenerator placement has been proposed.
122
A planning tool to design multi-stage passive optical networks, which includes the
proposal of an ILP (Integer Linear Programming) model and an efficient heuristic to
deal with the optimization problem, has been developed.
Investigation on physical layer impairments was pursued. An analytical treatment
appropriate to compute the performance of DPSK receivers in the presence of inband coherent crosstalk originated inside the optical nodes was developed.
Implementation of PON scenarios with power over fiber to the electric powered of
remote nodes. The viability of this solution was studied theoretically and
demonstrated with a laboratorial implementation, being possible to achieve an
average power transmission over 20 mW along 20 km of fiber.
In the areas of high power in optical networks, guidelines for the transmission of
high power optical signals in fiber systems were derived, and the constraints
resulting from the fiber heating and development of strategies to the mitigation of
the fiber fuse effect were studied. These studies were extended to analyses of
optical fiber rehabilitee under extreme conditions, such as high power propagation
and fiber degradation due to extreme climatic conditions.

impose by Raman amplification in optical communications. In
particular,
the

Title
Optical Sensors and Nanomaterials for Anion Recognition
Funding
FCT/PTDC
Descript.
The main goal of this project is to develop novel anion host
materials,
with
adequate
structural
features,
for
biomedical,
environmental and sensing applications. Based on our interest in the
development of an efficient technology for water treatment we
considered the possibility of supporting the most promising anion
receptors on magnetic nanoparticles, allowing their recovery using
external magnetic forces. Another goal will be the construction of a
refractive index sensor based on tilted fiber Bragg gratings (TFBG)functionalized by the most efficient synthesized hosts or by gold
nanoparticles wrapped also with anion hosts. These efforts will
be pursued in order to evaluate the potential applications of these
molecules
and
the
resultant
materials
to
be
used
as
anion
receptors.
This proposal aims five specific objectives having the overall goal of
exploiting
the
anion
properties
of
new
hosts
that
are
stated below: (Aim 1) develop robust precursors or platforms that
125
enable
rapid
development
of
new
compounds,
and
build
up
the target receptors based on porphyrin related compounds; (Aim 2)
develop
new
sensors
based
on
smaller
and
cheaper
commercial reagents like triazine and perfluorinated derivatives.
Such new materials should be able to host different types of
anions in selective and efficient ways, through their cavities or clefts;
(Aim
3)
screen
the
most
promising
materials,
evaluating
the anion binding properties of all new compounds/materials;
assessing
their
hypothetic
advantage
as
novel
anion
binding
agents, when compared with the present technologies; (Aim 4)
prepare
new
nanomaterials,
based
on
magnetic
nanoparticles
covered with small and cheap hosts, that can be recovered and
reused; (Aim 5) translate the anion binding results in solution into
the construction of novel optical fiber sensors, by wrapping a thinned
fiber Bragg gratings with the best selective anion hosts synthesized,
covalently or supramolecularly.

Descript.
The main objective of the Action is to establish active links between
European laboratories working in the field of artificial materials for
photonics applications, where the structural dimensions are at or
below the wavelength of light. Fabrication of such structures has
become possible due to the expertise delivered by nanotechnology,
which opens the way to the study of new functional artificial
materials
and
plasmonic
structures,
promising
progress
in
miniaturisation - and which will allow exploration of new aspects of
light-matter interaction. The goal is to increase knowledge about the
basic mechanisms of the interaction of light with matter on a subwavelength scale. The scientific innovation concerns: the basic
mechanisms of light-matter interaction in micro- and nanostructured
materials - including metals (plasmonics), the trade-off between
strong localization and propagation losses, photonic diagnostic
instruments, and non-linear effects. The technological impact of the
Action will lead to the implementation of advanced optical equipment
and devices with high performance and low cost. The scientific
128
transformation
resulting
from
the

will
facilitate
interconnection between topics that will produce new results in the
field of photonics and pave the way to the forthcoming era of

We will fabricate and characterize highly nonlinear fibers obtained by
tapering standard optical fibers. Highly nonlinear fibers will be used
to produce a super-continuum and to implement two all-optical
signal processing devices: i) an all-optical signal regenerator for
intensity modulated signals based on self-phase modulation (SPM)
and ii) an all-optical signal processing regenerator for nonlinear
phase noise reduction based on four-wave mixing (FWM) suitable to
be used in phase modulated signals. An accurate numerical
modelling and the design optimization of both tapered fibers (TFs)
and microstrutured fibers (MFs) will be realized, in the perspective of
their use to generate a wide and flat super-continnum, as well as
some nonlinearity-based optical signal processing functions, namely
the
wavelength

Title
Transmission of UltRa wide-Band radio signals over Optical fibre
Funding
FCT/PTDC
Descript.
This project proposes to investigate the performance impairments of
the orthogonal frequency division multiplexing ultra wideband
(OFDM-UWB) radio signal transmission in fiber-to-the-home (FTTH)
networks and optimize the system parameters through analytical
and numerical simulation work, and to experimentally demonstrate
the
main
results
obtained.
Particularly,
the
study
and
the
assessment of the main system impairments is performed, such as:
(i) electrical crosstalk associated with multi-channel OFDM-UWB
transmission, (ii) linear and non-linear fibre effects, (iii) optical
crosstalk associated with the transmission of several optical channels
using dense wavelength division multiplexing (DWDM). Different
techniques to reduce the performance degradation caused by such
limitations
are
also
investigated.
The work to carry out along this project targets the transmission of
OFDM-UWB
radio
signals
in
FTTH
networks
using
external
modulation (EM) and direct modulation (DM) of the emitter laser.
The transmission of OFDM-UWB radio signals over multi-mode fibre
is also a topic to be investigated in the project, since this type of
fibre is used in the user’s premises due to its easy maintenance and
utilization.

4.3.3.2 Processing, Analysis and Coding of Audio and Visual
Information
Distributed video coding
The main topics addressed were:
•
Definition of efficient encoder rate control solutions for transform domain
DVC, thus avoiding a feedback channel to perform efficient rate control.
•
Proposal of an iterative side information creation algorithm inspired in
video denoising filters and requiring some statistics of the virtual channel
between each side information hypothesis and the original data.
Perceptual video coding
The work focused on:
•
Extension and integration of a perceptual visual model in the High
Efficiency
Video
Coding
experimental
codec
to
improve
its
RD
performance. The designed extensions are related to the new Integer
Discrete Cosine Transform block sizes as well as the new Mode
Dependent Directional Transform. Moreover, an estimation mechanism
for the perceptual model at the decoder side is also integrated to avoid
the rate burden of sending to the decoder the model parameters.
•
Integration
in
the
state-of-the-art
H.264/AVC
video
compression
standard additional coding tools able to increase its rate-distortion
performance by better exploiting the human visual system behaviour.
This target has been fulfilled by including in the H.264/AVC basic
architecture
two
additional
perceptually
driven
changes:
first,
a
164
perceptually driven coefficients pruning method using the thresholds
provided by a selected just noticeable distortion model to set some of
the DCT coefficients to zero is integrated; after, an adaptive quantization
method adjusting the quantization error based on the same thresholds
has been included.
•
Proposal of a perceptual optimization of the H.264/AVC deblocking filter
offsets based on a quality metric able to quantify the blocking artifacts
impact on the perceived video quality. The proposed optimization in
made for the HEVC codec and involves low computational complexity and
provides quality improvements with respect to a non-perceptually
optimized H.264/AVC deblocking filter.
3D Holoscopic Video Coding
In 2010, research on video coding and processing techniques for 3D video were
initiated, focusing mostly 3D holoscopic video, which is a strong candidate for next
generation 3D television. A special attention was given to the estimation of spatial
prediction when encoding this type of content.
Other Video Coding Topics
•
Inpainting-based image codecs, able to improve the image compression
efficiency, by building on top of the JPEG image coding standard; its
rate-distortion performance was assessed using a novel methodology,
particularly suitable for perceptual image codecs.
•
Anovel depth map codec encoding the depth data by means of a binary
tree triangular decomposition and reconstructing the depth map values
by means of a triangle based planar approximation.
•
New ways of detecting errors for lossy transmission channels in
JPEG2000, as well as new algorithms for JPEG2000-based multipledescription video coding.
•
New algorithms for robust peer-to-peer video streaming using multiple
description coding.
•
A rate control technique for frame-based video coding systems, such as
those based on the H.264/AVC video coding standard, has been
developed.
165
Quality Evaluation
Continuing the work started four years ago, research has been focused on noreference, objective metrics for quality evaluation of video sequences, subject to
lossy encoding and transmission errors. Concerning the first issue (lossy encoding),
a new quality assessment algorithm for H.264/AVC encoded sequences has been
developed and published in IEEE Trans. on CSVT. Some preliminaries studies have
also been conducted in order to evaluate the use of simple network based metrics,
like the packet loss rate, and of their combination with video bitstream based
features, to quantify the perceived loss of quality due to transmission errors.
Video Analysis
•
Initial steps were taken to address the problem of 3D holoscopic images
analysis in view of their segmentation.
•
Work on the objective evaluation of video segmentation quality has been
continued, notably focusing on extending the existing metrics to better
reflect the temporal aspects of the human visual system.
•
In the field of video object detection and tracking for large public
environments, robust and efficient background modelling algorithms
have been investigated.
•
Work on the analysis of road pavement images for the automatic
detection of cracks and their characterization has been continued. This
type of analysis is valuable tool for the supervision and management
support of road infrastructures.
Medical Signal and Image Analysis
•
In gastroenterology imaging, we focused on emerging modalities, such
as Capsule, Narrow-Band Imaging, and High-Definition Endoscopy. Our
research addressed how computer vision techniques and tools can be a
key factor for developing automated or semi-automated computer
assisted decision systems for gastroenterology.
•
Auscultation is both a powerful tool for screening the generic population
for cardiac diseases and a hard clinical skill to master. Our motivation
was to address state-of-the-art digital audio signal processing research
challenges for extracting clinical features from auscultation, as well as
166
providing a clinical second opinion on specific heart pathologies. We paid
particular attention to aortic pulmonary signal decomposition and its
correlation
with
pulmonary
arterial
pressure,
researching
novel
algorithms that can enable us to assist clinicians in the detection of
pulmonary arterial hypertension situations. This is a good example of a
reasonably common and sometimes deadly pathology that is difficult to
detect by inexperienced physicians and which has a good prognosis when
detected early.
•
We have continued the work in the context of the “Vital Responder”
research project (funded by the CMU-Portugal program). Using Vital
Jacket® technology, our research team worked on signal processing
aspects and human-computer interaction problems.
•
We have exploited the use of computer vision and human-computer
interaction techniques as a way to automate the image capture and
analysis process in high-throughput microscopy imaging.
•
We have developed system for detection of cavities in pulmonary x-ray
images.
•
We have developed a system for the automatic assessment of carotid
intima-media thickness in ultra-sound data.
•
We have developed new approaches for early diagnosis and prevention
of woman breast cancer through computer aided diagnosis (jointly with
Siemens Healthcare Sector) using parallel computing-based 3D image
segmentation, as well as analysis of ultrasound images and case studies
regarding woman breast cancer (jointly with the School of Health
Sciences, UBI).
Computer Graphics
The main research tracks within this area were tangible interaction, triangulation
and rendering of implicit surfaces, water surfaces, molecular modelling, and
MMOGs. The following is a list of contributions achieved in 2010:
•
Multi-touch tabletop design. We have designed and constructed a multitouch tabletop, including the corresponding software, that allows for
167
running
interactive
applications
collaboratively
(jointly
with
PT
Inovação).
•

markers.
We
have
designed
and
implemented an algorithm to track fingers without using markers. The
idea is to be able to writing in-the-air as a mechanism of interaction in
human-aware computing environments.
•
Fluid simulation and rendering. We have developed and implemented
new algorithms for the simulation and rendering of fluids for computer
graphics and games applications, with a particular focus on water
surfaces.
•
Molecular modelling and rendering. We have developed and implemented
a constructive geometric method for DNA molecules, together with
triangulation algorithms for molecular surfaces.
•
Rendering of implicit surfaces. A new algorithm for implicit surfaces with
singularities was designed and implemented. This is an important for
rendering
surfaces
with
topological
guarantees,
as
needed
in
mathematical packages as Mathematica and Matlab.
•
Massively multiplayer online games (MMOGs). We have also developed
an re-engineering software principle to easily turn a multiplayer FPS
(first-person shooter) game like Quake into a massively multiplayer
online FPS game using grid technology.
•
Browser-based
augmented
reality.
A
number
of
browser-based
interaction techniques were developed using augmented reality and
WebGL (www.khronos.org/webgl).
•
Fault tolerance in On-line Games. In spite of not being a critical
application in the strict sense of the word, fault tolerance is a crucial
matter because a fault in online game servers leads to a negative effect
in the experience of the game. Players expect servers to be permanently
available and that periods when it does not happen become reduced or
even non-existent. Our work focus on exploring data and state
replication contributing to on-line games availability in case of fault.

Pattern Recognition and Automatic Learning
Biometrics
•
Work was developed on people recognition using biometrics. The
biometrics traits considered were the iris as well as several traits
obtained from a hand image, notably finger surfaces, palm print, hand
geometry and palm veins.
•
Research in the field of secure biometrics was continued. In particular,
the use of distributed source coding concepts and hash functions to
secure iris and hand biometric data was investigated. This approach
makes it possible to generate many different templates from the same
iris or hand, which can be cancelled if they are compromised.
Furthermore, it also guarantees that the original iris or hand data cannot
be recovered from the stored data, thus guaranteeing its privacy.
•
Authentication
and
identification
of
emotional
states
based
on
electrophysiological signals and on computer interaction data, was
another
important
area
of
research.
New
techniques
for
user
identification and authentication were explored using cross-parsing
algorithms for similarity quantification. Also, a set up for ECG acquisition
from fingers was implemented and tested, providing encouraging
preliminary results. A system for the invocation of emotional states was
developed, based on the playing of specific videos. Data acquisition is
being performed in order to achieve a database for the evaluation of the
assessment of emotion from electrophysiological data, namely EEG, ECG,
and EDA.
•
A system for biometric recognition and identification based on the ECG
signal was developed and published. The approach is non-fiducial and
based on information theoretic distances between symbol sequences,
obtained by quantization (uniform or Lloyd) of the ECG signal.
•
Analysis of degraded data acquired in unconstrained conditions, namely
without cooperation from the individuals to be identified. This puts in
evidence a number of challenges associated with reliable biometric
recognition.
We
have also
continued
our previous
work
on the
development of a non-cooperative multimodal recognition system. This
169
work has focused on gender recognition from face images, far infrared
people tracking, far infrared face image segmentation and the analysis of
the error rates regarding the accuracy of the segmentation stage of iris
images.
Kernel-Based Classification
In this area of machine learning, we have carried out novel work in several
directions.
•
We have applied non-extensive information theoretic kernels that we
have developed in recent years to several types of problems, including
scene classification and shape recognition.
•
We
have
proposed
a
stand-alone
online
multiple-kernel
learning
algorithm, which is based on the kernelization of the recent forwardbackward splitting schemes. The proposed method iterates between
subgradient and proximal steps. We also theoretically characterized the
algorithm by proving regret, convergence, and generalization bounds.
Compression Based Classification
We have continued to work on classification of sequence data based on lossless
compression algorithms of the Lempel-Ziv family (namely, the Ziv-Merhav method
and the Cai-Kulkarni-Verdú methods for the estimation of relative entropy from
sequences of symbols). Following the work carried out in 2009 on text
classification, in 2010 we applied this class of methods to the classification of
(quantized)
signals,
with
application
to
a
biometrics
problem:
recognition/identification based on the ECG signal.
Clustering
In the unsupervised learning area, research work during 2010 was devoted to the
clustering ensemble approach and focused mainly on four directions, deeply
grounded on similarity representations:
•
The EAC (Evidence Accumulation Clustering) method was used as the
baseline paradigm for the combination of clusterings. The probabilistic
interpretation of the learned similarity – summarized in a co-associations
170
matrix – was explored, leading to a new soft clustering combination
algorithm.
•
The issue of clustering validity was explored in two directions: validity of
partitions and validity of individual clusters within a partition. New
measures of validity were proposed and tested within these two
frameworks, either using statistical or dissimilarity based flavors.
•
Scalability
of
clustering
was
mainly
focused
representations. The idea of dissimilarity
on
using
increments
sparse
was further
analyzed and extended to higher order similarity measures. A theoretical
analysis of the baseline definition of dissimilarity increments led to a
new,
theoretically
grounded
and
more
exact
expression
for
the
distribution of these increments. The new expression was integrated in
two new clustering algorithms, one partitional and the other hierarchical,
intrinsic probabilistic criteria having also been proposed for solving the
parameter selection problem for these two algorithms.
Information Theory and Estimation Theory
We have continued to carry out fundamental research on the
intersections of
information theory and estimation theory and their applications in the analysis,
design and optimization of communications systems and in physical-layer security.
Speech Analysis
•
We have developed a new method to deal with coarticulation in
automatic phonetic transcription.
•
We have introduced a new automatic phoneme clustering method based
on confusion matrices.
•
We have carried out a study of syllable structure in dysfunctional
children speech.

Architectures and Protocols
Internet routing
•
A mathematical model was put forward and theorems were derived to
answer the seemingly simple question of finding the minimum number of
links in a network whose failure interrupts the flow of traffic from any
one node to any other. The problem is not trivial because routing policies
render some paths in the network unusable to carry traffic and because
these routing policies are realized with a routing protocol, the operation
of which hides routes and paths.
•
Use of concepts from temporal logics to rigorously derive correctness and
message complexities for the three main classes of routing protocols
operated in the Internet: distance-vector (RIP); path-vector (BGP); and
reset-on-failures (EIGRP).
•
Theory and practice of route aggregation. The Internet routing system is
under heavy stress and in urgent need to scale. We proposed and
evaluated the performance of novel route aggregation strategies
applicable to both intra-domain and in inter-domain routing. The route
aggregation strategies were validated with publicly available descriptions
of networks and of the Internet as a whole, and show aggregation factors
on the order of 90%. (JLS)
Transport protocols
We analyzed the performance of TCP and TCP with network coding (TCP/NC) in
lossy wireless networks. We build upon the simple framework introduced by Padhye
et al. and characterize the throughput behavior of classical TCP as well as TCP/NC
as a function of erasure rate, round-trip time, maximum window size, and duration
of the connection.
Our analytical results showed that network coding masks erasures and losses from
TCP, thus preventing TCP's performance degradation in lossy networks, such as
wireless networks. It is further seen that TCP/NC has significant throughput gains
over TCP. In addition, we simulated TCP and TCP/NC to verify our analysis of the
average throughput and the window evolution. Our analysis and simulation results
172
show very close concordance and support that TCP/NC is robust against erasures.
TCP/NC is not only able to increase its window size faster but also to maintain a
large window size despite losses within the network, whereas TCP experiences
window closing essentially because losses are mistakenly attributed to congestion
Wireless and sensor networks
Design, analysis, and deployment of a routing protocol for opportunistic networks,
exploiting device mobility to distribute data across the network.Development of a
middleware architecture with service discovery features covering entertainment,
security, communications and automation aspects.Research work related with plugand-play functionalities for IPv6-enabled wireless sensor networks was carried out.
Cross-Layer approaches for WSNs were surveyed and several studies on Mac layer
were performed.
High-speed networks
A new resource reservation protocol for OBS networks has been proposed and
developed, and multimedia applications and security issues on multimedia
applications were also addressed in our research activities.
Networking and security issues in real-time applications
This research stream focuses on problems related to high-speed network
infrastructures and security issues for real-time multimedia applications in an
evolution scenario where some applications and services have gradually migrated
from the client-server paradigm to the peer-to-peer (P2P) computing paradigm.
Particular attention was paid to the following issues:
•
Autonomic and Real-time Detection and Classification of Encrypted P2P
File Sharing Traffic and P2P TV Traffic;
•
Autonomic and Real-time Detection of Internet Traffic Anomalies;
•
Strategies for Robust Media Streaming over P2P Networks Based on

Environments;
•
High-speed Technologies, Protocols and Architectures for Multimedia
Networks.
Vehicular Delay-Tolerant Networks
In the area of Delay Tolerant Networks (DTN), we have proposed a new network
architecture called Vehicular Delay Tolerant Network (VDTN). The main objective of
this architecture is to provide a low-cost connectivity solution for isolated and
dispersed regions with no networks infrastructure. The proposed architecture can
be applied to various scenarios, including rapid deployment of emergency
communication systems when all communication links have failed. The work on
VDTNs is supported by the Internal Project VDTN@Lab, a joint collaboration
between Covilhã and Aveiro groups. Our group is also involved on the NoE Euro-NF
FP7-IST Project, leading the workpackage JRA 1.2 – Core and Metro Architectures
and leading the Specific Joint Research Project VDTN; other partners are INESD-ID
and UPC (Spain).
Vehicular Networking
A thorough understanding of the communications channel between vehicles is
essential for realistic modeling of Vehicular Ad Hoc Networks (VANETs) and the
development of related technology and applications. The impact of vehicles as
obstacles on vehicle-to-vehicle (V2V) communication has been largely neglected in
VANET research, especially in simulations. Useful models accounting for vehicles as
obstacles
must
satisfy
a
number
of requirements,
most
notably
accurate
positioning, realistic mobility patterns, realistic propagation characteristics, and
manageable complexity. We presented a model that satisfies all of these
requirements. Vehicles are modeled as physical obstacles affecting the V2V
communication. The proposed model accounts for vehicles as three-dimensional
obstacles and takes into account their impact on the LOS obstruction, received
signal power, and the packet reception rate. We utilized two real world highway
datasets collected via stereoscopic aerial photography to test our proposed model,
and we confirm the importance of modeling the effects of obstructing vehicles
through experimental measurements. Our results show considerable obstruction of
LOS due to vehicles. By obstructing the LOS, vehicles induce significant attenuation
174
and
packet
loss.
The
algorithm
behind
the
proposed
model
allows
for
computationally efficient implementation in VANET simulators. It was also shown
that by modeling the vehicles as obstacles, significant realism can be added to
existing simulators with clear implications on the design of upper layer protocols.

Security and quantum information
Quantum Information
•
Minimization
of
quantum
automata.
An
EXPSPACE
algorithm
for
minimizing several types of quantum and probabilistic automata was
developed. Two open problems were solved: one by Paz (1979) and
another by Moore and Crutchfield (2000).
•
Analysis of quantum error-correcting protocols. An analysis of a well
known
long/short
pulse
quantum
error-correcting
protocol
was
performed. The results show that the quality of the protocol decreases
exponentially with the distance of the long and short pulses and fiber
size when realistic fiber variations occur.
•
Quantum state distinguishability. A protocol for state distinguishability
that gives upper and lower bounds for the information that an attacker
can retrieve during the communication of a quantum cryptographic
protocol was developed.
Quantum security
Five quantum security protocols were proposed, two of them solve directly
cryptographic tasks: (i) contract signing and (ii) message signing; while the other
three are building blocks for constructing more complex protocols: (i) teleportation
of qudits,
(ii) dense coding of qudits, (iii) broadcasting of mixed states. The
contract signing protocol proposed does not require a trusted party, which is
impossible with classical asynchronous networks.
Formal verification
The development of the distributed temporal logic for security protocol analysis
DTPL was concluded. Formal methods for security protocol analysis beyond the
175
Dolev-Yao intruder model were addressed, including the development of efficient
algorithms for message deducibility and static equivalence under equational
theories
Health security
A
new
information-based
approach
to
assess
the
disagreement
on
the
interpretation of diagnostic tests and clinical decisions was proposed. The proposed
measure is based on the amount of information contained in the differences
between two observations. This measure is normalized and satisfies the flowing
properties: it is a metric, scaled invariant and it has differential weighting.
Moreover, evidence was given that grounded theory, together with mixed methods,
can be used to involve healthcare professionals in the design and enhancement of
access control policies to Electronic Medical Record systems.
Physical-Layer Security
We analyzed the role of jamming as a means to increase the security of wireless
systems. Specifically, we characterized the impact of cooperative/friendly jamming
on the secrecy outage probability of a quasi-static wiretap fading channel. We
introduced jamming coverage and jamming efficiency as security metrics, and
evaluate the performance of three different jamming strategies that rely on various
levels of channel state information. The analysis provides insight for the design of
optimal jamming configurations and indicates that one jammer is not enough to
maximize both metrics simultaneously.
Network Security
Wireless networks that allow for coding operations to take place at intermediate
nodes are particularly prone to active attacks by which malicious nodes inject
erroneous packets to corrupt the information flows. Seeking a solution for this
problem, we proposed a cooperative security scheme, in which neighboring nodes
cooperate to detect misbehavior. In this so called "algebraic watchdog", each nodes
observe the transmissions of other nodes and verifies whether they are complying
with the coding operations foreseen by the network coding protocol. It can be
shown that malicious behavior can be detected with high probability, as long as the
errors introduced by the attacker outweigh the noise in the channel. If this is not
the case, the errors can be corrected using forward error correction.
176
Random linear network coding can also be used in peer-topeer networks to
increase the efficiency of content distribution and distributed storage. However,
these systems are particularly susceptible to Byzantine attacks. We quantify the
impact of Byzantine attacks on the coded system by evaluating the probability that
a receiver node fails to correctly recover a file. We showed that even for a small
probability of attack, the system fails with overwhelming probability. We then
proposed a novel signature scheme that allows packet-level Byzantine detection.
This scheme allows one-hop containment of the contamination, and saves
bandwidth by allowing nodes to detect and drop the contaminated packets. We
compared the net cost of our signature scheme with various other Byzantine
schemes, and showed that when the probability of Byzantine attacks is high, our
scheme is the most bandwidth efficient.

Traffic Engineering
Quality of Service (QoS) and Quality of Experience (QoE)
Development of a prototype for the signaling support of FreeViewPoint applications
based on the open standards Real Time Streaming Protocol (RTSP) and Session
Description Protocol (SDP), and on metadata. Development of a prototype for the
integration of network generated context information in network architectures such

Proposal and performance analysis of congestion control mechanisms over paths
consisting of heterogeneous links with highly variable delays and bandwidths. Both
end-to-end congestion control mechanisms compliant with TCP and router-assisted
congestion control mechanisms are considered in this study.

Development of a server, a special purpose editor, and an extraction tool, all for
O3L ontologies.
Agent architectures
Agent architecture to dynamically decompose received problems into sub-problems
and their delegation to agents with the required skills to solve them.
Mobile and ubiquitous computing
In the area, we have proposed a location-aware application based on GPS. Mobile
health applications have been also proposed, and a few mobile multimedia
applications were developed to a point to have working prototypes.
E-Learning and m-Learning
We have worked on a proposal for an intelligent tutor for Escola da Malta portal
(from iZone KM), as well as on an e-learning approach for mobile devices (mlearning).Evaluation of an approach to learning mathematics in a classroom
environment making new uses of multimedia contents and presentation.
eHealth and Sensor Networks
We continued the work on sensors applications for eHealth where the novel intrabody sensor for vaginal temperature monitoring was realized. In addition to health
applications of wireless sensor networks and mobile and ubiquitous applications,
mobile solutions for body sensor networks monitoring were proposed, considering
Android, Symbian, Windows mobile and iPhone OS platforms.
Network Coding for Video Streaming
Emerging practical schemes indicate that algebraic mixing of different packets by
means of random linear network coding can increase the throughput and
robustness of streaming services over wireless networks. However, concerns with
the security of wireless video, in particular when only some of the users are entitled
178
to the highest quality, have uncovered the need for a network coding scheme
capable of ensuring different levels of confidentiality under stringent complexity
requirements. We showed that the triple goal of hierarchical fidelity levels,
robustness against wireless packet loss and efficient security can be achieved by
exploiting the algebraic structure of network coding. The key idea is to limit the
encryption operations to a critical set of network coding coefficients in combination
with multi-resolution video coding. Our contributions include an informationtheoretic security analysis of the proposed scheme, a basic system architecture for
hierarchical wireless video with network coding and simulation results.
We also presented an expression for the delay distribution of Random Linear
Network Coding over an erasure channel with a given loss probability. In contrast
with previous contributions, our analysis is non- asymptotic in the sense that it is
valid for any field size and any number of symbols. The results confirm that GF(16)
already
offers
near-optimal
decoding
delay,
whereas
smaller
field
sizes
(e.g.requiring only XOR operations) induce heavy tails in the delay distribution. A
comparison with Automatic Repeat reQuest (ARQ) techniques (with perfect
feedback) is also included.
Network Coding for Satellite Communications
The broadcast nature of satellite networks such as DVB-RCS based systems
provides a highly effective medium for content distribution, especially in the case of
geographically scattered clients. Non-real-time services typically rely on application
level protocols that often use forward error correction (FEC) and carousel data
cycling schemes in unidirectional links. The presence of a feedback channel in
satellite networks is mostly unexploited in the context of reliable multicast services.
We showed that network coding protocols offer a native and transparent solution
for reliable multicast over satellites. When employing a feedback channel, network
coding can reach near real-time performance at an efficiency level close to known
theoretical bounds for lossy satellite links.
Capacity of Channels
Shannon defined channel capacity as the highest rate at which there exists a
sequence of codes of block length n such that the error probability goes to zero as
n goes to infinity. In this definition, it is implicit that the block length, which can be
179
viewed as the number of available channel uses, is unlimited. This is not the case
when the transmission power must be concentrated on a single transmission, most
notably in military scenarios with adversarial conditions or delay-tolerant networks
with random short encounters. A natural question arises: how much information
can we transmit in a single use of the channel? We gave a precise characterization
of the one-shot capacity of discrete channels, defined as the maximum number of
bits that can be transmitted in a single use of a channel with an error probability
that does not exceed a prescribed value. This capacity definition is shown to be
useful and significantly different from the zero-error problem statement.
Intelligent Transportation Systems
Understanding driver behavior is critical towards ensuring superior levels of safety
and environmental sustainability in intelligent transportation systems. Existing
solutions for vital sign extraction are generally intrusive in that they affect the
comfort of the driver and may consequently lead to biased observations. Moreover,
low-complexity devices such as GPS receivers and the multitude of sensors present
in the vehicle are yet to be exploited to the full extent of their capabilities. We
presented a real-life system that combines wearable non-intrusive heart wave
monitors with a wireless enabled computing platform capable of gathering and
processing the data streams of multiple in-vehicle sources. Observed variables
include electrocardiogram, vehicle location, speed, acceleration, fuel consumption,
and pedal position, among others. Preliminary results show that the proposed
system is well suited not only for characterizing driver behavior but also for
identifying and mapping potentially dangerous road segments and intersections.

3D VIVANT
Title
Live Immerse Video-Audio Interactive Multimedia
Funding
EU, FP7
Descript.
The aim of the project 3D VIVANT is to capture events automatically in
3D and deliver them for realistic, interactive and immersive play back
to home users-viewers. This will require the project to create, develop
and integrate a comprehensive range of components from the generic
technology of 3D imaging. Real and virtual 3D content will be
homogeneously combined/mixed producing a novel form of rich and
interactive content, defined as “3D Holoscopic content”. 3D Holoscopic
imaging is a technique for creating full colour 3D optical models that
exist in space independently of the viewer. The images exhibit
continuous parallax throughout the viewing zone. The continuous
nature of the images produced with this method eliminates the effect of
'cardboarding' (flattening of objects into discrete depth planes) and
flipping (a visible effect created by moving between image fields)
present
in
multiview
stereoscopic
systems.
Unlike
multiview
stereoscopy, information about a point is contained in many different
parts of the image plane. In this respect 3D Holoscopic imaging is akin
to holography. However 3D Holoscopic imaging is more advantageous,
since it can operate under incoherent illumination, which is in contrast
with holography, and hence it allows more conventional live capture
and display procedures to be adopted. Furthermore, in viewing the 3D
optical model accommodation and convergence work in unison (i.e. the
viewer’s eyes focus and converge to the same point) to prevent eyestrain from occurring.
The 3D VIVANT project will investigate the possibility of using different
technologies for capture and display of 3D content. For the capture, 3D
VIVANT will take full advantage of 3D Holoscopic imaging technology,
where a single camera is required. Hence in this project a world first
182
single aperture ultra-high definition 3D Holoscopic imaging camera will
be constructed which will permit live capture of 3D content. For the
display, the project will take advantage of Holography to provide
immersive, ultra high resolution presentation of 3D content. To
increase the immersive experience, the generation and playback of 3D
spatial sound is also investigated. The developed system will be tested
using two user cases, namely, broadcasting and online hyperlinking.
For this purpose various 3D Holoscopic video processing algorithms,
such as 3D codecs and 3D object segmentation, as well as search and
retrieval techniques will be developed.

Title
3D video adaptation based on perceptual metrics
Funding
National Science Foundation - QREN
Descript.
The research work in this project is focused on 3D video stream
adaptation methods capable of maximizing 3D perceptual quality under
different sets of known constraints. The joint interdependencies
between rate, 3D perceptual distortion and decoding complexity will be
investigated using subjective evaluation and validation procedures.
Adaptation of 3D video streams is mainly targeted at rate, format and
decoding complexity adaptation, taking into account that 3D video
includes more parameters suitable for adaptation which provide an
increased level of flexibility (e.g., the 3D signal is coded into two
streams which might undergo through different channel errors and
constraints, variable depth distortion in the spatial and temporal
domains producing similar perceptual quality, asymmetric distortion in
stereoscopic video, effect of error concealment methods in 3D
perception, etc). The project research is also concerned in devising
power-aware
adaptation
functions
such
that
decoding
power
consumption is reduced at the expense of minimum quality cost. This is
an open topic for research in 3D video since decoding is far more
183
complex than monoscopic video and the need for low complexity
decoding
is
higher
because
of
limited
battery
life
and
lower
computational resources in portable decoders.

Title
Affective Mouse

QREN
Descript.
This project aims at determining the role of emotions on the learning
process and the way in which these can influence the results of the
process. The goal is to develop a Human-computer interaction device
(which is envisioned as a computer mouse) that measures multiple
electrophysiological signals from the children and simultaneously allows
the interaction with a multimedia Web application with games and
educational exercises. Thus we want to know how different activities
influence
the
physiological
signals
while
completing
the
exercises/games on the Web platform. The system will allow the tutor
to follow-up the learning process, adopt incentive measures, and adjust
the learning process according to the emotive signals of the children.
As a result of the R&D project a physiological signal database will be
produced on didactic and cognitive exercises, this way creating a base
structure for advanced studies in affective computing and real
interaction/learning environments.

followed by a converter from phonemes to visemes. In the case of text

Title
BioSec
Secure Multimodal Biometric Recognition System using Distributed
Source Coding
Funding
FCT/PTDC
Descript.
Biometric recognition systems target the automatic recognition of a
person’s identity based on physical, physiological or behavioural
characteristics (something a person is or produces). In particular,
verification systems perform one to one authentication, comparing the
captured biometric data with that person’s own biometric template (a
mathematical representation of the biometric features extracted during
the
enrolment
phase)
previously
stored
in
the
system.
One of the major vulnerabilities associated to biometric recognition
systems is that once a biometric template becomes compromised, it
cannot be reissued, updated or destroyed. An attacker could then gain
access to all the accounts/services/applications using that same
biometric trait. The main goal of the project is to create a secure
multimodal biometric verification system, supporting the generation of
different templates from the same biometric data, as well as cancellable
templates. Furthermore, the privacy of the original biometric data
needs to be guaranteed, not allowing its recovery from the stored data.
State-of-the-art methods will be extended by considering a biometric
verification system based on distributed source coding principles and
cryptographic hash functions, to enhance security with respect to
185
traditional
biometric
systems.
The
additional
consideration

Previous work on fundamental aspects of wireless sensor networks has
mostly focused on communication-oriented models, in which the sensor
nodes are assumed to store and process the data, coordinate their
transmissions, organize the routing of messages within the network,
and relay the data to a remote receiver. Although some of these
models provide useful insights (e.g. into the connectivity characteristics
or the overall power efficiency of sensor networks) there is a strong
need for formal methods that capture the inherent processing and
memory constraints, and illuminate the massively parallel nature of innetwork computation. Our take is to develop process calculi for sensor
networks building on formalisms for concurrent distributed systems and
mobile code (most notably, pi-calculus). The envisioned tools will
enable us to (a) prove the correctness and feasibility of different data
187
gathering and communication protocols (e.g. by exploiting behavioral
equivalence between processes), and (b) carry out formal comparisons
of different schemes by quantifying the minimum amount of required
resources.
Based on the results of the first task we will attack another
fundamental problem in sensor networks: the need for sensor
programming languages with self-configuration and distributed update
capabilities. We propose to develop specifically tailored high level
idioms for sensor networks that capitalize on notions such as mobile
code and self-maintenance. Finally, we will implement and test the
developed programming tools on a sensor networking prototype. Reallife experiments will allow us to better understand sensor networking
constraints and further improve our designs. We believe that our
interdisciplinary team of computer scientists and electrical engineers is
well equipped to contribute both in theory and in practice to the
advancement of sensor network programming.

This project addresses the problem of correct symbolic abstractions of
cryptographic primitives for the purpose of symbolic, automated
188
proving of security properties of protocols.
Computer security has been of major interest in the past two decades.
This field provides both interesting research problems and important
applications to everyone's life such as e-commerce and e-government,
hence the need for designing better and safer security protocols.
Proving security of protocols however is a difficult task that sometimes
cannot be performed by hand, therefore several tools have been
designed to deal with such a complex problem [B01,BMV05,P98]. But
the need for such (automated) tools is not only due to the complexity
of the protocols. If we consider the simple protocol proposed by
Needham and Schroeder in 1978 [NS78], it was not until 1996 that
Lowe discovered his famous attack on the protocol using the CSPmodel checker FDR [L96] and suggested a fix. The attack used a flaw in
the protocol design, the encryption itself was assumed to be perfectly
secure. With this ''perfect'' cryptography assumption the protocol is
simple enough to be easily analyzed by standard model-checkers and
theorem provers. The fix was shown to be safe as long as encryption
was perfect. But what happens when the cryptographic primitives are
not perfect, which is the case in real life where we can always guess a
key with small probability? After some positive results regarding
cryptographic soundness of such abstractions, Warinschi [W03] showed
that the same attack discovered by Lowe against the NS protocol, could
be performed against the corrected version if a somewhat weak but
standard encryption scheme is used, the El-Gamal encryption scheme.
This result turned the attention of the research community for the need
of soundness results for formal cryptography, ie, the importance to
characterize when protocols proved correct using perfect cryptography
are correct when implemented with computational cryptography.
Computational soundness of formal cryptography is an active research
area and members of this team have been involved in several of its
fronts [ABS05,ABHS05,ABHS09,AF06,AFGZN08,BHO07,BHO09,BMS06]
Symbolic models provide abstractions for the study of cryptography
that are amenable for automatic verification of complex protocols but
assume ''perfect cryptography'' [DY93]. Messages, keys, encryptions,
189
attacks,
all
appear
as
formal
objects
described
with
symbolic
operations, axioms, derivation rules; cryptographic operations are
modeled as functions on a space of symbolic expressions and security
properties are also treated symbolically. This method ignores the
probabilistic nature of encryptions. It provides a powerful way to
describe how an adversary may interfere, corrupt, deceive participants
of a protocol, and grab this way information not addressed to him. This
method
is
much
easier
to
handle
mathematically
than
the
computational, the proofs can be automated but, as the probabilistic
nature is ignored, security within this framework does not necessarily
mean security in the real world. Real probabilistic attacks that are
outside the framework of this model may still happen [W03]
On the other hand in the computational model cryptographic operations
act on strings of bit and their security properties are defined in terms of
probability
and
computational
complexity
[GM84].
Computational
security proofs make use of techniques of these theories; proofs have
to be done by hand (ie cannot be automated) and are different for each
protocol. Good protocols are those in which attackers cannot do
something bad too often and efficiently enough. This is a very detailed
description, closer to reality as it involves the notion of efficient
computation, hence complexity and probabilities. However, even for
mildly complex protocols this approach simply becomes too difficult and
impossible to handle.
The unification of these two models is absolutely necessary for symbolic
security proofs to be trustable. So far in the literature there are
fragmented attempts done by different research groups, but as their
treatment lack sound mathematical basis, the results themselves and
how they are related are questionable
AR02,ABHS09,AF06,BPW03,C01,CC08,DDMST05,MW04]
We expect this research project to deliver new insights to the
relationship between the symbolic and computational models, clarify
the applicability and limitations of existing approaches to this problem,
and provide sound mathematical foundations that can be used in the
future as a common framework and technique for sound symbolic
190
abstraction of new cryptographic primitives.
The ultimate goal of this research is to develop/adapt fully automated
tools for symbolic models that, via our soundness results, entail strong
cryptographic
guarantees
to
the
computational
model,
hence
substituting the tedious complexity-theoretic proofs of computational
cryptography by automated ones

Funding
FCT/PTDC
Descript.
The grand objective of the research project DEWICOS: Design of Next
Generation Very High Data Rate Wireless Communications Systems is
to exploit a novel framework based on the interplay between
information theory and estimation theory to lay the foundations for the
design of next generation very high data rate wireless communications
systems. In the last decade wireless communications have experienced
an explosive growth with the demand for higher data rates to
accommodate new services growing rapidly ever since. A number of
wireless systems have been gradually introduced including novel mobile
and fixed wireless systems, e.g., 2nd and 3rd generation mobile
systems as well as WiFi (IEEE 802.11) and WiMax (IEEE 802.16). This
wireless communications revolution is being fuelled by constant
technological breakthroughs to enhance transmission performance in
the wireless setting. For example, major advances that dominated
research efforts in the past decade concerned the development of
multiple antenna transmission schemes, as well as the development of
powerful error correcting coding schemes, such as turbo codes and lowdensity parity-check (LDPC) codes. In fact, these powerful techniques
are now gradually being incorporated into wireless communications
standards and commercial products. Notwithstanding, the optimization
of the reliable information transmission rate – the Holy Grail in
communications – is still an open issue at large of paramount
importance in communications systems research and practice, offering
the prospect of communication at ever increasing information rates.
The major difficulty relates to the absence of appropriate mathematical
tools and methodologies due to the presence of complex features in
communications systems, thereby motivating system designers often to
resort to other criteria, engineering experience, and insight to optimize
the system. Building upon foundational work on the interplay between
193
information theory and estimation theory, this project proposes a
different paradigm to the analysis, design and optimization of wireless
communications systems: We will capitalize on the relation between
mutual
information,
which
measures
the
reliable
information
transmission rate between the input and the output of a system, and
the non-linear minimum mean-squared error (MMSE), which measures
the minimum mean-squared error in estimating the input given the
output, to overcome in an innovative way the inherent difficulties
concerning the optimization of the reliable information transmission
rate of key communications systems. The research project is divided
into three complementary tasks, which culminate with the application
of the ideas to relevant communications scenarios and applications. The
first task leverages the intersections between information theory and
estimation theory in order to establish insight into the optimal structure
of standard elements of communications systems. The focus will be on
establishing concrete design guidelines for optimal transmit filters,
optimal receive filters as well as resource allocation procedures in
relevant communications scenarios, ranging from deterministic to
wireless fading channels and single- to multi-user channels. The
objective of the second task will be to develop practical algorithms,
with a good tradeoff between issues such as accuracy, efficiency,
complexity and convergence, in order to perform optimal filtering and
resource allocation in communications systems. In addition, taking into
account
that
the
reliable
information
transmission
rate
is
only
achievable with powerful error correcting codes, this task will also
investigate the integration of the optimal designs with powerful error
correction codes, such as turbo codes or LDPC codes. The objective of
the third task will be to evaluate the impact of the optimal designs – in
combination with powerful error correcting codes – on the reliable
information transmission rate of practical communications scenarios
and standards such as WiFi, WiMax and LTE wireless networks, as well
as digital subscriber (DSL) lines. Overall, the research team, consisting
of
key
research
groups

complementary topics such as information theory, estimation and
194

which are necessary to meet both the theoretical and practical
challenges of this research. High-level publishable (and possibly

In the ears of an experienced physician, a stethoscope yields important
clinical information which can help an initial assessment of a patient’s
clinical condition and guide the subsequent need for more specialized
exams. Auscultation is both a powerful tool for screening the generic

auscultation, as well as providing a clinical second opinion on specific
heart pathologies. We pay particular attention to aortic pulmonary
signal decomposition and its correlation with pulmonary arterial
pressure, researching novel algorithms that can enable us to assist
clinicians in the detection of pulmonary arterial hypertension situations.
This is a good example of a reasonably common and sometimes deadly

Evidence Accumulation in Unsupervised and Semi-Supervised Learning:

The main objectives of this project are twofold:
1. To provide original, state-of-the-art contributions to the area of

2. To address the practical, real world problem of automatic structuring

The key idea of semi-supervised learning, specifically constrained
clustering, is to exploit both a priori information, and unlabeled data to
organize data into sensible groups. A priori information can be provided
as labeled data, or as constraints (usually pair-wise relations) that one
wishes
to

or
just
encourage.
We
focus
on
pair-wise
associations, which are to be defined from available a priori information,
or provided by means of user queries or data mining techniques on the
application domain, exploring semi-structured data from multiple
sources. Specifically, we will address the problem of active acquisition
of constraints, by identifying key-objects at cluster boundaries, and
exploring
boosting
approaches.
A
particular
breakthrough
on
semisupervised learning is expected by its extension into the cluster
ensemble framework.
Cluster ensemble methods are a recent and very promising research
area in clustering. Introduced in 2001, it was given increasing attention
by the scientific community, both from theoretical and application
domain perspectives. It is our goal to make novel contributions to this
topic, in particular addressing the following issues: (a) processing of
large data sets, focusing on efficient and scalable algorithms; (b)
dimensionality reduction, through feature selection and extraction
197
techniques; (c) use of a priori information, in a semi-supervised

that
the
increasing of the amount of exercise can positively influence biological

excessive loading, both in intensity as well as frequency and volume,

on
architectural/structural, functional and neuromuscular chronic and acute

undergoing exercise routines, of moderate to high mechanical cyclic
loading.
To accomplish the study of the biological tissue chronic and acute

two
complementary
approaches will be used: (1) in vivo imaging methodologies (magnetic

(2)
biomechanics modeling. We are concerned with the changes in muscle
and tendon stiffness, cartilage thickness and collagen arrangement. The
neuromuscular control systems are sensitive to neural fatigue, and this
can be measured through EMG. These changes will be assessed and
introduced into the models throughout the redefinition of the activation
process. Structural and functional analysis of cartilage and muscletendon complex before and after mechanical load will be available from
MRI and SE. The resulting information will be correlated and those
changes will be related with the estimated joint loading (using
biomechanical modeling). All this data will be further analyzed applying
clustering techniques for exploratory data analysis, crossing it with the

brings
many
challenges to the pattern recognition task, namely due to the many
types of non-deal images that result of the imaging conditions and
acquisition protocols (at-a-distance, on-the-move and under dynamic
lighting conditions) The proposed approach to deal with these extremely
challenging conditions is based on the concept of negative (a-contrario)
recognition, i.e., to prove that an individual is not among a group of
people already known to the system. The key insight is that although
the quality of the captured data possibly denies the positive recognition
with enough confidence, perhaps it is still possible to assure that data is
not correspondent to a subset of the enrolled templates, which for most
of the everyday situations is the essential. The range of potential
applications to the type of system proposed for this project is obvious.

Indeed, this type of applications is regarded for the Pattern Recognition

Next Generation Network Operations and Management
Funding
FCT/CMU
Descript.
Effective network management has been widely recognized as a grand
challenge. Enterprise networks spend an increasing amount of their IT
budgets (up to 70% in 2008) in order to only maintain their current
operating environments, rather than to add new, value-adding services
and equipment. A $1000 server that demands annual maintenance cost
of $2000 illustrates a simple example of the management problem.
This excessive cost of network management is mainly due to the large
scale of networks, the heterogeneity of different technologies, and their
subtle interactions. The goal of NeTS is to develop a novel network
operation and management framework that departs from conventional
approaches through a cross-disciplinary research collaboration based
on hierarchical network abstraction modeling, structure learning of
probabilistic graphical models for machine learning, and wavelet and
kernel-based signal processing technologies. In multiple phases, NeTS
will be progressively deployed in the Portugal Telecom (PT)’s operation
and management of high definition IP/TV network to illustrate the
impact of our proposed research. High Definition IP/TV network is one
of the highest growth services for PT and is regarded as a key strategic
area in PT. The grand challenge of this complex network is to deliver,
205
without failures, a high quality service efficiently – this requires novel
management/operations systems to detect anomalies, identify their
root-causes, and predict future network behavior in real time. Existing
network management systems for IP/TV are generally focused on
monitoring and on simple correlation of events analysis; using these
management systems still incurs in excessive costs and delays. NeTS
will be deployed online in part of PT’s IP/TV network in order to assess
its performance and expected network operations and management
cost reduction. Network operators will play a key role in assessment
and fine-tuning of our systems. Our approach to this research problem
is significantly different from conventional approaches that focus on
monitoring and correlation analysis. We bring together insights from
network abstraction and statistical and heuristic machine learning
methods and closely tie them to build an intelligent network abstraction
model. Network insights show that the network configuration dictates
the behavior of the network control plane and the network control
plane dictates the behavior of the data plane. We bring configuration,
control and data plane abstraction models together with probabilistic
graphical models to derive an intelligent and predictable network
abstraction model of an enterprise network. Further novelty of our
approach consists of performing automatic learning of the graph
structure using concepts from Bayesian model selection, information
theory, and optimization; this will be done step-by-step using first
static network configuration elements, then by summarization and
filtering of dynamic control plane information, and finally of data plane
information. Once a graphical model is obtained for the network, we
will perform inference on the graph to identify anomalies and their rootcauses and to predict future network behavior. Finally, we will explore
the concept of forcing function to impose restrictions on the network
configuration that simplify the graphical model and the inference
process. This project heavily leverages on previous network abstraction
modeling work with PT in last 3 years. The direct impact of this
research will be on the network operations and management of PT’s
IP/TV service. Although at this point it is not possible to say what the
real impact will be, we anticipate a reduction of at least 30% on
206
network operations and management costs. This is supported by the
anticipation that support teams will be directed to a single extremely
likely root cause of a failure rather than to multiple possible failure
points, that root-causes will be detected in the time-span of seconds
rather than days, that service may be brought up in minutes s rather
than days, and that network behavior and failures may be anticipated,
thus reducing down time several orders of magnitude. We expect other
enterprise network-supported services may also benefit from NeTS
because the network modeling and management functions researched
in
this
project
are
generic
to
enterprise
networks.
To achieve NeTS’ goals, we formed an interdisciplinary team that
includes experts in Networking (Dr. Sobrinho, IT/Lisboa, Dr. Kim,
ECE/CMU and Dr. Alegria, PT), Machine Learning (Dr. Cardoso,
INESC/Porto
and
Dr.
Morla,
INESC/Porto),
Information
Theory,
Communications and Signal Processing (Dr. Rodrigues, IT/Porto), as
well
as
Optimization
(Dr.
Xavier,
ISR/Lisboa).
Furthermore,
we
obtained a strong collaboration commitment from Portugal Telecom
with their operational experiences and manpower that will be explored
during all phases of the research project (see attached letter of support
from PT). We plan to integrate several PhD students who are already
enrolled in (e.g. Tiago Carvalho and Tiago Quelhas) and in the process
of applying to the CMU-Portugal program. It is also important to note
that we have created various PhD-level courses within the CMUPortugal program in topics directly relevant to this research proposal,
as well as taken the responsibility for advanced courses within the
CMU-Portugal Master’s program in Information Networking. Class
projects for graduate and undergraduate students will also focus on
research issues that contribute to the success of NeTS. Furthermore, PT
employees who are enrolled in the Master’s program will work on NeTS
projects and continue their work when they return to PT after
completion of their degrees. CMU and Portuguese PIs will ensure that
project development, milestone achievement, and partner coordination
are on track with plan and take measures to correct any deviation to
the project timetable. This will be facilitated by the existence of
previous work between partners e.g. PT and CMU and shared PhD

Title
Novel information processing methodologies for intelligent
sensor networks
Novel information processing methodologies for intelligent sensor
networks
Funding
FCT/CMU
Descript.
Over the past few years, we have witnessed tremendous advances in
the miniaturization of low cost electro-mechanical devices that exhibit
several
sensing
capabilities
(e.g.
temperature,
pressure,
vision,
etc) and possess signi cant embedded processing and low-range
wireless communication. This triggered interest in wireless sensor
networks (WSN) where large collections of such small wireless
sensor nodes are scattered across critical geographical areas or
infrastructures to execute a variety of monitoring and acting tasks.
While the use of WSN is crucial to assess the state of a physical
system, the ultimate engineering goal is to control such system to
perform certain desired tasks. We refer to systems that close the loop
around
wireless
sensor
networks
as
cyber-physical
systems
(CPS). Cyber-physical systems are physical and engineered systems
the operations of which are monitored, coordinated, controlled and
integrated
by
a
computing
and
communication
infrastructure.
Examples of CPS include medical devices and systems, aerospace
systems, transportation vehicles and intelligent highways, defense
systems,
robotic
building
and
systems,
process
environmental
control,
control
factory
and
automation,
smart
spaces.
To realize the immense potential bene ts of CPS in real-life applications,
a plethora of novel problems lying at the intersection of statistical
signal processing, control, communication theory, and distributed
optimization, must be addressed. Indeed, it is clear that to achieve
desired networkwide detection, estimation or control objectives, system
designers should deal eciently with simultaneous challenges, typically
208
tackled in separate engineering disciplines. The challenges include
securing energy-ecient operation as the nodes are usually batteryoperated
and
constrained
to
small
power
budgets,
developing
distributed analogues of centralized signal processing and control
algorithms,
coping
with
the
dynamic
communication
topology
interconnecting the sensing nodes, dealing with the random nitebandwidth wireless medium, etc. The need for this interdisciplinary
e ort is mirrored in the creation of this project's research team which
gathers signi cant expertise in a wide range of complementary topics in
the disciplines of control, signal processing, optimization, information
theory, along with the private technology company ISA (Intelligent
Sensing Anyhwere) which holds a vast experience in the deployment of
sensing networks for telemetry, environmental monitoring and energy
eciency.
The main goal of this project is to address certain key research issues
in the eld of wireless sensor networks and map the research results into
implementations on prototype testbeds, thereby showcasing real-life
applications with social and economic impact. More precisely, the
expected outcomes of this project are:
1. Fast algorithms for sensor selection While energy-eciency is of a
lesser concern in wireless LANs, it is of critical importance in
large-scale wireless sensor networks (WSN), as the in-situ unattended
sensors are typically powered by nonrechargeable batteries. Thus,
aggressive restraints on sensor usage must be observed to ensure a
prolonged WSN lifetime. When the WSN is used for event discrimination
(e.g., intruder/no intruder, re/no re, etc) this translates into nding
which minimal subset of the deployed sensing nodes is sucient to
activate for a given query, whilst securing a prescribed detection
performance. It is clear that nding the optimal subset of sensors
represents
a formidable optimization challenge. Indeed, forming all possible
combinations of few sensors and checking the respective performance
is computationally intractable even for moderate network sizes.
Additionally, a WSN is typically immersed in a noisy environment
209
subject to various degradation factors such as wireless fading and
interference phenomena. These induce communications constraints
between the sensors themselves or between the sensors and a fusion
point responsible for the decision. It is thus important to explicitly
account for the impact of this adverse phenomena in the design of
reliable sensor selection algorithms. In this project, we will develop fast
(non-combinatorial) optimization algorithms for several sensor selection
application scenarios which strike a desirable tradeo among detection
performance, computational complexity and robustness with respect to
the fading wireless medium.
2. Secure WSN communication schemes Security is an issue of
paramount
importance
in
current
communications
systems
and
networks.
The wide deployment of wireless sensor networks, together with the
broadcast nature of the wireless medium, calls for advanced secure
mechanisms to protect potentially sensible information against possible
eavesdroppers.
Traditionally, security is viewed as an independent feature with little or
no relation to the remaining data communication tasks and, therefore,
state-of-the-art cryptographic algorithms are insensitive to the physical
nature of the wireless medium. However, there has been more
recently a renewed interest on information-theoretic security - widely
accepted as the strictest notion of security - which calls for the use of
physical-layer techniques exploiting the inherent randomness of the
communications medium to guarantee both reliable communication
between two legitimate parties as well as secure communication in the
presence of an eavesdropper. This paradigm is particularly interesting
for wireless sensor networks since it may not be possible to secure
information using state-of-the-art complex cryptographic protocols
due to energy budget considerations. In this project, we will study the
fundamental
security
mechanisms
pertaining
to
the
sensor
network communications medium by exploiting tools from information
theory. In addition to revealing the secrecy limits of wireless sensor
networks, we will also construct speci c transmission schemes
210
appropriate to convey information between sensors and a fusion point
in a reliable and secure manner, taking into account the energy and
bandwidth restrictions of sensor networks.
3. Secure Control of Cyber-Physical Systems Modern cyber-physical
systems raise signi cant engineering challenges because of their scale,
their need to bridge the physical, information and communication
technology domains and their need to operate eciently, securely and
reliably. Today's methods and tools for control systems engineering are
unable to systematically cope with such requirements. Security, in
particular, must enter the design process and cannot be considered an
afterthought. Today's designs are mainly driven by performance/cost
considerations, resulting in brittle systems susceptible to attacks
starting from both the physical and cyber side. The problem arises
because CPS tend to be open systems, accessible both physically and
through the communication network. The increasing use of the Internet
will allow attackers to execute their attacks remotely. Next generation
systems
will
be
particularly
susceptible
to
security
threats
if this concern is not addressed at design time. CPS, di erently from
traditional IT systems, not only have to be able to detect malicious
attacks but they need to guarantee continuity of operations under
attack,
perhaps
with
decreased
functionality,
through
graceful
degradation rather abrupt. They also need to be able to recon gure to
eradicate attacks and restore full functionality. We propose to introduce
a
new
approach
to
control
systems
design,
by
formally
de ning security attacks on control systems and by developing tools to
analyze the e ect of security attacks, to design attack resilient control
systems and develop quantitative metrics to assess the natural tradeo
between security and performance.
4. Testbed and Implementation We propose the employment of an
experimental
platform
to
validate
the
outcomes
of
the
research. ISA will assist in de ning the set of applications that better
align with both their business and with the current market trends. We
will adopt the Sensor Andrew platform available at Carnegie Mellon at
the
rst
stage,
with
the
plan
to
enhance
the
platform
211
and
deploy a smaller scale testbed at IST in Portugal at a later stage.
Sensor Andrew is a project aimed a building a large scale wireless
sensor-actuator network infrastructure on the CMU campus. The
testbed comprises the basic sensor and actuator hardware, the
software
that runs on this hardware allowing access to the sensor and actuator
hardware, and nally the network protocols and services required to
support
communications
and
routing
within
large-scale
sensor
networks. We plan to build an event noti cation system that will allow
us
to perform sensor selection, event detection and real time control using
the Sensor Andrew platform. At the core of the system is the use of an
XMMP server that allows timely retrieval of selected sensor data and
delivery of control commands. This infrastructure will allow us to
validate the proposed methodologies and algorithms in a real setting,
to assess its robustness to uncertainties and resilience to security
attacks.
The vision of this project is to advance CPS and WSN design by
integrating
expertise
outperforming
the
along
common
several
key
methodologies
dimensions,
which
thereby
ignore
their
interdependence.
This is re ected in the formation of the project team which aims at
realizing this fruitful synergism between multidisciplinary academic
researchers and a highly experienced industry partner. In the detailed
outline of the proposed research, we expose clearly how this project
builds on such interaction, by describing how each team member
participates in the four main lines of research aforementioned.
Moreover, the outcomes of this project are also of direct interest
to the running FCT project URBISNET-Urban environmental networked
sensing
using
a
public
transportation
infrastructure
(PTDC/EEA-
CRO/104243/2008), and collaborative work with the URBISNET sta will
leverage both projects.

Performance Optimisation in 3D TV Broadcasting Services
Funding
IT
Descript.
This project addresses the emerging 3D TV broadcasting services by
investigating the problems associated with transmission of different
stereo video coding formats. It is comprised of two main parts that run
in parallel and communicate between each other by exchanging
technical information in order to optimise the performance of the
broadcasting system in terms of received quality and channel useful
capacity. The research on 3D video deals with characterisation and
optimisation of 3D video coding algorithms by developing and testing
suitable error resilience methods for broadcasting such type of content.
On the decoder side the project addresses error concealment methods
to cope with transmission errors and improve the quality delivered to
users. The particular issues related to coded depth information are
receiving special attention in this project as this is the major
component of 3D video which makes it different from classical 2D.
Appropriate distortion measures for depth will be used to optimise
performance. The project makes use of the most recent video coding
standard for video (H.264/AVC) and its extension for multiview coding
(H.264/MVC).
Finally, a method to characterise the radio propagation channel will be
developed for varying deployment scenarios. A refined method is
required to effectively measure the signal coverage in DVB-T networks
and to extract the effective parameters for the error pattern generator
required for both source and channel coding optimisation of DVB-T
transmissions. Additionally, the measured data to be obtained and
included in a database for various geometries and at a number of
frequencies will represent a quantum improvement, both in volume and
accuracy of the database presently available to system designers. This
will form a framework to radio system designers to propose fading
mitigation techniques based on link level analysis using the proposed
213
error pattern generator.

Important research questions: how should WSNs be integrated into the
Future Internet and what special challenges do they present to
designers and implementers, taking into account that all aspects of the

Moreover, to be able to compare different proposed solutions with

ReAlImage
Regularization
Criteria
and Fast Algorithms for Imaging Inverse
Problems
Funding
FCT/PTDC
215
Descript.
The goal of the project is to advance the state of the art in criteria and
algorithms for solving imaging inverse problems. The research fronts
that we aim to push forward are the following:
a)
In
standard
photography,
and
even
more
in
computational
photography (CP), deconvolution plays a key role. In the standard case,
deblurring is used to compensate lens softness, while in many CP
applications (e.g., coded aperture) deconvolution is itself responsible for
producing the images. Even with the CP ''friendly'' direct operators,
prior knowledge (regularization) is required to solve the IP. In this work
front, we will develop new regularization criteria, beyond the currently
used sparseness-inducing 1-norm and total-variation. In particular, we
will consider: compound regularizers; criteria that adapt automatically
to the intrinsic complexity and/or the local structure of the underlying
image; non-local regularization (which has only been used for pure
denoising problems, with excellent results).
b) Realistically, full knowledge about the convolution operator is seldom
available: the exact motion causing a motion blur is of course unknown;
coded aperture imaging is highly sensitive to the exact knowledge of
the aperture, which is usually obtained by a previous careful calibration
procedure. These observations stress the general importance of blind
deconvolution. In this topic, we will research criteria for blind
deconvolution, for problems with varying degrees of uncertainty about
the direct operator. In particular, we will take steps towards the ''holly
grail'' of blind deconvolution: an objective function whose minimization
yields optimal image and convolution estimates.
c) Some of the currently fastest algorithms for CS and image
deconvolution
under
standard
regularizers
were
developed
by
researchers in the project team. The new criteria mentioned in (a) and
(b) will result in new, more challenging optimization problems, requiring
new algorithms. This will be the third core research direction of the
project, continuing our successful recent line of work. Bregman
iterations and augmented Lagragian methods will be fundamental tools
in our quest.

SearchCol
SearchCol: Meta-heuristic Search by Column generation
FCT/PTDC
Many relevant practical problems can be modeled as combinatorial
optimization problems (COPs). Examples are the definition of routes for
vehicles,
schedules
for
machines,
or
the
dimensioning
of
telecommunication networks. Meta-heuristics (MHs), such as tabu
search or genetic algorithms, are the most successful methods in
providing good-quality solutions in reasonable amounts of time for
large-size instances of several COPs.
The aim of this project is to propose a new MH, entitled Search by
Column generation (SearchCol), for COPs. SearchCol algorithms will be
applied in specific problems from four areas: production planning and
scheduling, telecommunications, forest management, and cutting and
packing. The main distinctive feature of SearchCol is that its ingredients
(such
as
construction
of
solutions,
neighborhood
structures,
or
crossover operators) are based on column generation (CG). We aim at
proving that a suitable search strategy (provided by the hybrid MHs
framework) taking advantage of decomposition exact methods (CG)
quickly leads to high-quality solutions for NP-hard COPs. The evidence
is that CG provides tight lower bounds (in minimization problems) on
the optimal value and that the columns belonging to the restricted
master problem define a search space where high-quality solutions
exist.
The drawbacks of standard MHs (the lack of ameasure of the quality of
the solution obtained and the lack of a well defined stopping criterion)
are overcome in SearchCol since the lower bound provided by CG is
available.

Beyond features: similarity-based pattern analysis and recognition
217
Funding
EU, FP7 ICT
Descript.
The challenge of automatic pattern analysis and recognition (or
machine learning) is to develop computational methods which learn to
distinguish among a number of classes from examples, with a view to
endow artificial systems with the ability to improve their own
performance in the light of new external stimuli. This ability is
instrumental in building next-generation artificial cognitive systems
which, as opposed to traditional machine or computer systems, can be
characterized as systems which cope with novel or indeterminate
situations, which aim to achieve general goals as opposed to solving
specific problems, and which integrate capabilities normally associated
with people or animals. The socio-economic implications of this
scientific endeavor are enormous, as it will have applications in a wide
variety of real-world scenarios ranging from industrial manufacturing to
vehicle control and traffic safety, to remote and on-site (environmental)
sensing and monitoring, and to medical diagnostics and therapeutics.
This project aims at bringing to full maturation a paradigm shift that is
currently just emerging within the pattern recognition domain, where
researchers are becoming increasingly aware of the importance of
similarity information per se, as opposed to the classical feature-based
approach. Indeed, the notion of similarity has long been recognized to
lie at the very heart of human cognitive processes and can be
considered as a connection between perception and higher-level
knowledge, a crucial factor in the process of human recognition and
categorization. We shall undertake a thorough study of several aspects
of purely similarity-based pattern recognition methods, from the
theoretical, computational, and applicative perspective. We aim at
covering a wide range of problems and perspectives, considering both
supervised and unsupervised learning paradigms, generative and
discriminative
models,
and
our
interest
will
range
from
purely
theoretical problems to real-world practical applications. We shall apply
our algorithms to challenging biomedical problems that lend themselves
particularly well to similarity-based approaches, namely, to the analysis
of tissue micro-array images of renal cell carcinoma and to magnetic
218
resonance brain imaging for the diagnosis of mental illness.

The objectives of this project are the following: 1) Development of a
methodology to detect P2P file-sharing traffic in local area networks for
further blocking of its source. As far as we know only limited solutions for
this problem are available, which lead to large performance degradations
even at moderate network speeds (e.g. 100 Mbits/s). The methodology to
be developed might be validated in an experimental environment. It is
expected that the method and apparatus for the detection of P2P traffic
should result in an international patent. 2) Proposal of a new trust
mechanism for P2P system, taking into account the dynamic properties of
peers and avoiding a large traffic overload. A trust model addressing both
problems is lacking. The new trust model based on dynamic weights for
P2P networks will be investigated in order to overcome both problems. 3)

The objectives are to maximise resource transmission efficiency whilst
guaranteeing the quality (of experience) and minimising the effort for each
entity/operator. In line with these objectives, optimization mechanism
account for:
• Information from the different protocol stack layers to optimize the
219
subscriber access performance, and the creation of cross-layer design
interactions whilst optimizing the quality of experience (QoE) metrics;
• Interaction among the different network entities to make the service
available to the subscribers in an optimized way, taking the possibility of
having different companies operating the backhaul and the access
networks. The focus of the research activities will be the following:
• To identify, monitor and optimize QoE metrics for voice and video
services in these networks by considering the support of an hierarchy of
mesh networks for the identified scenarios;
• To define cross-layer mechanisms to optimize the impact of the
developed QoE metrics into the concatenated mesh network performance.
Our research will explore mechanisms for efficient use of spectrum, for the
shared medium access and routing onto the concatenated networks,
transport issues, as well as the usefulness of context awareness, e.g.
positioning,
the
distribution
of
the
velocities
and
active
services;
• To apply game theory concepts to optimize the cooperation among the
different agents: subscriber terminal access network nodes (gateway to

• To use pricing models to analyse the benefit associated with agent as
well as the interactions among different network operators through the
use of the optimization methodologies previously proposed.

Gestão de Mobilidade Centrada no Utilizador Final

FCT/PTDC
Descript.
The work to be developed in this project relates to the topic of global
mobility management in spontaneous wireless environments, i.e.,
environments that self-adjust to any network topology change. Global
mobility management is addressed from a network perspective, and the
purpose is to ensure a transparent access to Internet services (e.g Triple
Play) for the end-user, who will be able to access his/her subscribed
services independently from access attachment point, location, and
220
based upon his/her own requirements (“Quality of Experience”, QoE). In
addition, global mobility management is to be analyzed from a decentralized perspective, given that environments to be considered will
incorporate wireless local-loops that are based upon end-user willingness
to cooperate. Main aspects to focus upon are:
1. Handover management optimization
a. Consider QoE as well as available (aggregated) spectrum to provide
the user with the best possible connection seamlessly at any time and
independent of location, having in mind user expectations.
b. Analyze and validate adequate cost functions and metrics to estimate
QoE levels on-the-fly.
2. User-centric mobility management
a. Investigate and validate algorithms for a self-organized selection of
anchor-points, aiming to insure system robustness to highly frequent
changes.
b. Devise a global mobility management mechanism taking into
consideration the aspects analyzed in relation to handover optimization
and incorporating mobility models that support adequate anchor point
selection.

VERE: Virtual Embodiment and Re-Embodiment
Funding
EU, FP7 ICT
Descript.
This project aims at dissolving the boundary between the human body
and surrogate representations in immersive virtual reality and physical
reality. Dissolving the boundary means that people have the illusion that
their surrogate representation is their own body, and act and have
thoughts that correspond to this. The work in VERE may be thought of as
applied presence research and applied cognitive neuroscience, and it
would also significantly add to scientific knowledge in these areas .
Imagine that you could transfer your self to an artificial body – a virtual
body as represented in virtual reality or a physical robotic body. Recent
221
advances in cognitive neuroscience show that internalising a body
beyond ourselves (external, remote, alien) is possible, that our body
representation is highly malleable and may be altered by appropriate
changes to the normal stimulus contingencies that we are used to in
every day life.
The purpose of this research is to make such body transference possible
with two different modes (virtual and physical). On top of this technical
achievement, that would be underpinned through ongoing neuroscience
research on body representation, would be a number of practical
applications that will be constructed and investigated during the project.

4.4.3.2 Applied Mathematics
Research was developed in the following fields of Mathematics: Optimization and
Numerical Linear Algebra. Apart from some more theoretical oriented studies, our
research
has
mainly
been
focused
in
the
design,
convergence
analysis,
implementation and testing of algorithms for the solution of many important
problems in these areas. We have also been collaborating with researchers of other
areas in the design and solution of some models of engineering and finance. The
most relevant topics are presented below.
•
Numerical Linear Algebra: Preconditioning and convergence of iterative
methods for the solution of linear systems of equations.
•
Complementarity
Problems:
design,
implementation,
convergence
analysis implementation and testing of interior-point algorithms, activeset methods, sequential quadratic algorithms and enumerative methods.
•
Global Optimization: complementarity algorithms, positive semi-definite
and reformulation-linearization techniques for bilevel programming,
quadratic and bilinear programming and mathematical programs with
complementarity constraints.
•
Discrete
Optimization:
global
optimization
algorithms
for
linear,
nonlinear and complementarity problems with integer variables.
•
Solution of Structured Optimization Models, namely finance models and
eigenvalue complementarity problems.
•
Design and solution of models in telecommunications.
280
During 2010 research on Security and Quantum Information was carried out in the
following topics:
A-Logic
•
Parallel composition of logics. Capitalizing on the graph-theoretic
account of logic systems and their fibrings, and inspired on notions of
concurrency,
composition
a novel form of combination of logics — parallel
—
at
the
semantic
level
was
investigated.
This
combination mechanism allows both symmetric (like sharing) and nonsymmetric (like triggering) forms of interaction to be specified at the
signature level, and subsumes fibring as a special case. The
conservative
nature
synchronization
using
of
parallel
a
generalized
composition
bisimulation
under
lossless
technique
was
established.
•
Graph-theoretical account of logic calculi as generalized 2-categories.
First steps were taken towards a graph-theoretical treatment of
deduction.
•
Importing logics. The notion of importing logics was introduced,
subsuming as special cases several kinds of asymmetric combination
mechanisms,
like
temporalization,
modalization
and
exogenous
enrichment. This novel logic combination mechanism is then proved to
be strongly conservative.
•
Abstract algebraic logic. The development of the behavioral approach
to abstract algebraic logic was continued, namely by proposing an
algebraically well-behaved notion of valuation semantics and showing
that it parallels in richness the well-known theory of logical matrices
and their connection to the traditional approach to algebraic logic.
Algorithmic aspects of logics defined by possibly non-truth-functional
finite-valued valuation semantics were also studied.
281
B-Complexity
•
Computability in dynamical systems. Results relating classical topics
from dynamical systems theory (Smale horseshoe, stable manifold
theorem, domains of attraction) with computability were obtained.
•
Analog computation and verification. Lower and upper bounds on the
computational power needed to solve the reachability problem for
Lipschitz
dynamical
systems
operating
under
the
presence
of
perturbations were established.
•
Sophistication for infinite sequences. A new definition of sophistication
for infinite sequences was proposed. The set of sequences with
sophistication equal to zero was shown to have Lebesgue measure one
and it was also proven that the set of sophisticated sequences is
dense. The set of deep infinite sequences was shown to be dense.
Finally,
it was proven that sophistication and depth for infinite
sequences are distinct information measures.
4.4.3.3 Instrumentation and Measurement
Scope and Objectives
The Instrumentation and Measurement Group works in the broad domain of
Metrology. In 2010 the main topics addressed were:
•
Analogue-to-digital and digital-to-analogue conversion;
•
Measurement of electrical quantities;
•
Non-destructive testing
•
Sensors and transducers;
•
Signal acquisition and automated and telemetric measuring systems;
•
Signal processing applied to sensors and instrumentation.
•
Swarms robotics
282
Analogue-to-digital and digital-to-analogue conversion
•
Study of the uncertainty of analog to digital converter test methods,
namely of the Histogram Test Method, the Random Noise Test Method
and the the Sine Fitting Test Method. Consideration of different non-ideal
effects like additive noise, jitter, phase noise and harmonic distortion.
Measurement of electrical quantities
•
In the context of a contract, a DSP based three phase power quality
analyzer was implemented. The device is to be used within a commercial
product and it will monitor power quality in accordance with the norms
and to assess the quality of service in multiple locations in the power
distribution grid.
Non-destructive testing
•
The research work during 2010 was mainly related with the PTDC/EEAELC/67719/2006 and I.T. internal project CLASSE that aim at classifying
defects inside conductive non-magnetic plates. The application was
extended to determine thicknesses.
A new constant field probe was designed. This probe is based on the
generation of a sinusoidal magnetic field with constant amplitude inside a
limited area, and the detection of the secondary field accomplished with
a bridge of giant magneto-resistor sensors. The new probe was
registered in the patent PT104826.
Another important aspect of the work carried out was related to the so
called quantitative non-destructive evaluation QNDE of defects in metallic
materials. In this work the aim was not related to the detection of
defects, but mainly to the characterization of those defects in a
quantitative way. Thus, by using direct problem solvers that are enough
simple to be included in an iterative cycle, the solution of the inverse
problem was attempted. This case study was related to the geometrical
characterization of a straight crack in an aluminium plate.
The use of algorithms implemented using DSPs to process and interpret
sensors data proved to be very effective to overcome their poor
performance. Significant improvements in the crack position accuracy
283
and resolution were obtained. Some of the crack characteristics like
length and orientation are now obtained using the measurement system
developed at the Instrumentation and Measurement Laboratory.
Novel low-cost handheld instruments to detect cracks and other defects
in a plate of conductive material have been implemented and the
prototypes are working properly. One of these instruments uses a planar
excitation coil with a giant magnetoresistor as the sensing element and
the visualization of the defect can be depicted in real-time on a LCD
display. Besides the output voltage with the sensor location can be
transmitted to a PC for further processing. The other instrument is able
to measure both amplitude phase of the sensor output voltage
(corresponding
to
the
secondary
magnetic
field
with
the
crack
information) and transmitted to the PC wirelessly to be depicted as
phasors.
Sensors and transducers
•
A new dsPIC based impedance measurement systems was designed,
developed and implemented for a viscosity sensor. The principle of
operation of the sensor is based on a vibrating wire immersed into the
liquid whose viscosity is to be measured. The characteristic of the sensor
that is changed by the liquid viscosity is the impedance resonance
frequency as well as the width of the resonance. Since the measurement
is done on a wire, the amplitude of the impedance is very low which
requires special care in the design of the analogue interface of the
measurement system and carefully designed calibration procedures.
Progress in the interoperability of marine observatories has been carried
out.
Sensors
with
analogue
outputs
will
have
their
connectivity
augmented with an embedded Transducer Electronic Data Sheet, which
contains technical information to identify the sensor. Data will be
formatted according to IEEE 1451.0 standard and interoperability in
OBSEA and MBARI observatories is already a fact concerning some
equipment issues.
Some work based on the Precise Time Synchronization Standard, IEEE
1588 has already started. Ocean observatories are an important
technological
resource
that
can
provide
knowledge
to
forecast
284
environment changes or to ocean research. Sensor data is collected at
different world locations and large streams of data must be correlated
with other events or data sources to study either long term tendencies or
singular events. To allow this analysis data in a location context must be
time-stamped.
For many observations a low time-stamp precision is adequate but, for
other observations, like hydrophones and seismometers, the millisecond
precision level is needed. Now the project and implementation of a “GPS
virtual pulse-per-second signal generator” to be installed at OBSEA
observatory to timestamp sensor data in a submillisecond range is being
carried out. OBSEA is a cabled seafloor observatory 4 km offshore
Vilanova I la Geltru (Barcelona, Stain) at 20 m water depth,
interconnected to the coast by an energy and communication mixed
cable.
Static and dynamic characterization of sensors and measurement system
(polarography, heavy metals detectors, turbidity, pH and conductivity
sensors). One paper was presented in one international conference and
an extended version was submitted for publication in Instrumentation
and Measurement review.

4.4.3.4 Integrated Circuits and Systems
Scientific activities under this topic followed six lines described in the following
sections. In some cases, the actions taken resulted also on industrial contacts at
both national and international levels.
288
Energy Efficient Concepts for Public Illumination Systems
This topic represents a new trend on the usual activities of this group. It departed
from the gathered knowledge on solid state lighting devices, LEDs, also explored for
other objectives. Public illumination systems are predicted to be dominated by solid
state lighting devices in the next few years. LEDs, present several advantages to
other illumination devices in current use. The exploitation of these advantages and
the advancement of collaborative control strategies for these systems are currently
a hot topic for both research and industrial sectors. The activities under this line of
research started with the participation on an International funded project, involving
several participants from the European community (project LITES: CIP-ICT-PSP2008-2/238916). The major achievements under this line of research are the
dissemination of the group activities both at national and international levels, and
the direct contact of several actors from the industrial sector that may result in
future collaborations.
Energy Efficient Integrated Circuit Amplifier Design
This line of research results from the gathered experience of this group on the field
of integrated circuit design. The main objective is to advance new design strategies
able to optimize circuit performance without impairing power consumption. The
expected outcome will be to achieve energy efficient amplifiers. Until this point the
research on this line was concentrated on the analysis and deployment methods for
minimum power consumption in amplifiers. This line of researched is supported on
a national funded project (project EECCO: PTDC/EEA-TEL/105314/2008).
Tdoa Telemetry for Wildlife Tracking Systems
Traditional telemetry solutions for wildlife tracking and surveillance resort to two
main approaches: RF tracking systems, and GPS based data loggers. RF tracking
systems are crude and require human intervention. On the other end, GPS based
data loggers have the ability to be very accurate, but they are also very expensive.
Moreover, GPS based systems are not a god choice for small animals (as for
instance the case of small birds). This has led the Integrated Circuits group
members to advance a new solution able to deliver accurate position information,
and to reduce the volume of the identifiers. This solution is based on TDOA (Time
Difference Of Arrival) measurements. Initial research as demonstrated the
feasibility of our intents. It was also established a close cooperation with
289
researchers from Biology. This line of research has result on a project proposal
(project BIRDS: PTDC/EEA-TEL/120831/2010).
Saw Based Sensors Development and Design
Under this line of research the main objective is to develop SAW based sensors,
using diamond film layered structures. Diamond films are especially interesting due
to their resilience to adverse conditions. This line of research resulted from the
cooperation of the Integrated Circuits group with researchers from the Mechanical
Engineering department at the University of Aveiro. The activities under this line of
research are under the framework of a national funded project (project JISIS:
PTDC/EEA-TEL/104004/2008).
Radio Astrnomy Methods for Deep Space Exploration
The research under this line has proceed through three main project lines: i) The
GEM project: test of COTS based digital complex cross-correlator for polarimetry
application and ultra-low noise LNA manufacture; ii) The SKA project: test on site in
Moura of SAR based Aperture Arrays (with the presence of the President of the
Republic), with Nokia Siemens Networks ICT contribution. Co-Supervision of
engineer on signal transport design for SKA network (40G, 100G); and iii) The CorE
- Cosmic Origins Explorer, an M3 proposal study for the next generation of
microwave space probes, submitted to ESA. The mission was later selected by ESA
for further analysis (Member of the scientific Consortium).
Visible Light Communication System Design
The research under this topic has started several years ago, with project VIDAS
(PTDC/EEA-TEL/75217/2006). The main objective of this project was to explore
visible light as a communication means for driver assistance systems. Traditional
lighting devices are not suitable for communication purposes due to their
persistence between switching states. This is the case of both incandescent and
discharge devices. LEDs, on the other end, enable fast switching operation, thus
potentiating other applications rather than lighting. VIDAS project elaborated use
LEDs for both signaling and communication purposes. The research on this topic is
reaching to important conclusions. A real demonstrator was assemble to show that
visible light can be used for communication at low data rates, and also, that
290
evolved modulation techniques, such as spread spectrum, are required to combat
the presence of noise (especially on outdoor scenarios).
Design Automation applied to Optimal Circuit Sizing
A new design automation tool, based on a modified genetic algorithm kernel, in
order to improve efficiency on the analog IC design cycle was developed. The
proposed approach combines a robust optimization with corner analysis, machine
learning techniques and distributed processing capability able to deal with multiobjective and constrained optimization problems. The resulting optimization tool
and the improvement in design productivity was demonstrated for the design of
CMOS operational amplifiers.
Design Automation applied to Class-D Amplifiers Topology Exploration
and Circuit Sizing
An automated design methodology for continuous time loop-filters dedicated to
Class-D amplifiers, aiming the optimization of both THD and noise was defined. This
methodology is based on a modified genetic algorithm kernel, and a set of
performance rules that integrates both the topology selection and circuit sizing by
automatically generating and sizing filter topologies to minimize the loop THD and
noise, but replacing traditional and very long transient and steady-state simulations
by fast AC evaluations. The evolutionary algorithm accepts any kind of SPICE like
simulator as its evaluation engine, multiple filter topology templates and a set of
design constrains and fixed component values can be included on the process
adding flexibility. The approach was demonstrated for the design of a fully
differential BTL class-D loop filter topology that achieves less than 0.003% THD at
680mW output power while maintaining the base-band noise term below 4ìVms.
DC/DC Converters for the Space Industry
The design of state-of-the-art DC/DC converters for low power applications for
aerospace industry was initiated baring in mind the integration of the control circuit
of the DC/DC converter. A first silicon prototype was released by the end of the
year.
291
HIGH-SPEED Pipeline ADCs
A complete electrical design of a new multiply-by-two amplifier to be readily used in
ultra high-speed medium resolution pipeline ADC stages was proposed. It is based
in a switched-capacitor open-loop structure but with the novelty of having the gain
accuracy improved by using an active amplifier with local feedback. Simulation
results demonstrate that, with a very low-power dissipation and without employing
any digital self-calibration or gain-control techniques, the circuit exhibits, over PVT
corner and device mismatches, a dynamic performance and a gain-accuracy
compatible with 6-bit level.

4.4.3.6 Power Systems
Fault Analysis and Development
•
Of permanent magnet synchronous motor drives – In this research field,
the main goal was to investigate the faulty operating modes of these
variable speed ac drives, with special focus on power converter failures.
Considering
this,
several
work
was
carried
out
concerning
the
devolvement of mathematical models that allow to simulate the drive
behaviour, including the analysis under faulty operating conditions.
Furthermore, experimental tests were performed where power converter
293
faults
were
carefully
introduced
and
their
impact
on
the
drive
performance investigated.
•
Of wind turbine power conversion systems based on permanent magnet
synchronous generators – Due to arising interest on renewable energy
systems and considering the complex power converter systems used in
these specific drives, in this research area, special attention is given to
the faulty analysis of these power conversion systems. A theoretical
analysis was carried out through computational simulations. Moreover,
some laboratory tests were also performed, being the drive performance
investigated by the analysis of some key parameters.
•
Of power converter faults – Variable speed ac drives are being more and
more used in the industry and as result, it becomes important the
availability of diagnostic tools that can perform a correct diagnostic of
the drive operating status. Following this, the main objective of this
research topic is to develop fault diagnostic methods for power
converters in ac drives. The most important challenge is to develop
algorithms that can be easily integrated into the main control system,
having therefore low computational requirements. Furthermore, it is
desired that the algorithm uses variables already available from the main
control system in order to avoid the use of extra sensors. Important
work was already done by the development of new algorithms for realtime fault diagnosis in power converters.
•
Development of fault-tolerant variable speed drives – Due to the
widespread adoption of variable speed drives and thanks to their
complexity, these energy conversion systems are very susceptible to
suffer critical failures. This can be extremely undesired, especially for
critical applications, where unplanned stoppages can result in very large
costs or in even more catastrophic consequences. For these reasons, the
development of fault-tolerant strategies applied to variable speed ac
drive systems is mandatory. Considering this, it is intended in this
research field to develop fault-tolerant drives applied to switched
reluctance motors, permanent magnet synchronous motors and wind
turbine power conversion systems using permanent magnet synchronous
generators. In a first stage, the drive control system must be able to
294
detect and identify power converter failures. Then, the system must be
able to isolate the faulty device and proceed to hardware and software
reconfigurations that allow the system operation, with possible limited
conditions. Several simulations and experimental results were already
obtained, showing the effectiveness of the developed strategies.
•
Development of fault diagnostic methods for induction motors –
Induction motors, currently, are very used in a wide range of industrial
applications. For this reason, the availability of diagnostic methods for
these specific electric machines can help to improve the reliability levels
of a great number of applications and allow to drastically decrease the
unintentional stoppages. In this context, the main objectives of this
research is the development of diagnostic tools for induction motors
concerning rotor broken bars, short-circuit faults and eccentricity faults.
These methods must be effective when the machine is directly supplied
by the grid and by a power converter in open-loop control. Research is
also being done to detect rotor faults when the induction motor is fed by
a power converter in closed-loop control.
•
Development of protection systems and diagnostic methods for fault
detection in three-phase transformer windings – Power and distribution
transformers have formed an essential part of electricity supply networks
since the alternating current system was adopted more than a century
ago. In general, transformer breakdowns are relatively few, but repair
and
replacement
of
large
transformer
units
means
considerable
expenditure and time, and further, if faulted units are not cleared quickly
and selectively can cause serious damage and power system stability
problems. Protective schemes applied to transformers thus play a vital
role in the economics and operation of a power system. Considering this,
the main objective of this work is the development of protection systems
and diagnostic methods for three-phase power transformers. The
research is focused on detailed analysis and characterization of the
transformer behavior under the influence of inrush currents and incipient
winding faults such as turn-to-turn faults.
295
Telecommunications Power Supply Systems
•
In this research field, it is intended to develop a prototype of an
autonomous supplying system for telecommunication equipment based
on renewable sources. The system should combine different renewable
power sources such as wind generators and photovoltaic panels since,
beyond their environmental advantages, they can represent a unlimited
power source which fulfils the requirements for remote standalone
telecommunication systems.
•
In an extension to the research topic mentioned in the previous topic, in
a second stage, fault diagnostic methods for the different power
converters that compose the entire system will be developed and tested.
All the system modelling is being carried out using the MATALB/Simulink
software and currently some parts of the experimental prototype,
namely the photovoltaic panels, are being installed and tested.
•

of
the
power

and
most
telecommunications energy systems present a special energy supply
challenge, requiring reliable, unattended power system operation in
locations where grid power is not available. The main objective of this
research is the study of new technologies for the generation and storage
of energy for telecommunications applications. A software tool will be
realized using available commercial computation programs integrated
with ad hoc program modules developed for the specific application. This
tool will allow to analyze the hybrid combination of different components
in order to improve and optimize the overall energy output and to reduce
energy storage requirements.
•
Hybrid

for
telecommunications
–
Telecommunication facilities require the simultaneous presence of
different energy vectors. In such perspective the implementation of
trigeneration or Combined Heat Cool and Power (CHCP) plant, with
integrated renewable energy
sources (Hybrid Trigeneration System),
can play a key role in reducing the fuel consumption and
emissions .
pollution
The research on this subject is actively under way with
296
particular focus, on a first stage, about the energy requirements of a TLC
system and the potential generation of the three energy vectors by the
hybrid CHCP system.
Traction Electric Drive Systems
•
Currently, with the increasing demand for environmentally friendlier and
higher fuel economy vehicles, the automotive companies are focused on
the development of hybrid and electric vehicles. Considering this, the
main objectives of this research area are focused on the development
and implementation of different electric drive systems for electric/hybrid
vehicles. It is intended to develop control strategies that allow to
optimize
the
drive
operation
under
several
operating
conditions,
including the regenerative braking mode. Some simulations results were
already obtained and experimental tests are being carried out.
•
Multi-level power converter topologies applied to electric motor drives –
Multi-level power converters have gained a lot of interest for medium
and high voltage applications and now they are starting to be used for
low power and low voltage applications. This technology is based in the
simple concept of connecting in series several power switches or power
converters, allowing the use of semiconductors with less rated voltages.
When applied to electric motor drives, among other advantages, they
allow to achieve higher overall efficiency values. Considering this, it is
under research the comparison of a typical two-level inverter and several
multi-level inverter topologies in the performance of induction motor
drives. Currently, all the system components are being modeled in
MATLAB/Simulink for simulation. A detailed model of an induction motor
is also under implementation in a finite element analysis software.
Regarding the experimental setup, a lot of information is being collected
in order to start to build a multi-level converter prototype.
•
Electric drives based on matrix converters – Recently, there has been an
increasing interest in the development and use of electric drives based
on matrix converters. Due to the advantages offered by the matrix
converter, namely its inherent bidirectional power flow capability,
297
associated with a controllable input power factor and sinusoidal input
currents, it is expected that other areas of application such as aerospace
and military will also embrace the use of this type of drive in a near
future. Taking this into account, the main goal of this research area is
the study of matrix converters applied to induction motors. A lot of work
was done, namely the construction of a fully-functional matrix converter
prototype. Fault diagnostic techniques were also developed for these
specific power converters, leading to the publication of several papers.
Characterization of Aluminum Electrolytic Capacitors Equivalent
Circuit
Electrolytic capacitors are one of the electronic components that is extremely used
in an enormous variety of applications, starting in low power applications such as
small electric and electronic devices to high power applications such as variable
speed drives. For these last ones, they are typically used at the DC bus working as
a filter. However, due to their characteristics, electrolytic capacitors are one of the
components that are responsible for the major part of faults in these high power
applications. Considering this, the main objective was the development of

Thermal Analysis of Induction Motors
•
As far as both motor losses and temperature rise are concerned the
supply conditions imposed by frequency converters, have introduced new
problems. Additional losses in the iron, stator windings and rotor bars
are among then. These losses are highly dependent on the inverter
fundamental working frequency and on the harmonic content of both
motor phase voltages and line currents. All these losses bring additional
heating inside the motor that lead to motor temperature rising and the
subsequent degradation of the windings insulation. Considering this, it is
intended to develop finite element simulation models that can accurately
298
model the temperature behavior of induction motors when supplied by
power converters. Some work was already done in this field regarding
the construction of the machine model. Experimental work is also
carrying out in order to evaluate the machine temperature when it is
supplied by an unbalanced system.
Maintenance Management os School Buildings
•
This area of research concerns asset management of Portuguese
Educational Facilities, namely infrastructure and fixed equipment. The
Portuguese Educational System is a complex structure and, therefore,
any suggestions to improve maintenance management must be based on
the objective identification of those areas needing improvements, as the
first step of an overall maintenance improvement process. The specificity
of the several levels of education refers not only to pedagogical practices
but also to spaces, installations and equipment policies management,
human and material resources management, as well as financial and
administrative management. The main goal is to develop theoretical
models that typify maintenance management and organization of
educational facilities, allowing the development of computational decision
support tools for Maintenance management and organization.
Electronic Ballasts
The lighting industry is a global, multibillion industry, with even more money spent
on the energy consumption of these light sources. With energy conservation
concerns becoming increasingly high, electronic ballast consumption is expected to
be stronger. A number of factors are contributing to this growth rate, including
government
regulations,
lower
prices,
innovative
technologies
and
energy
efficiency. It is intended with this work to develop new topologies and technologies
for electronic ballasts with special focus on dimming and efficiency. Good simulation
and experimental results were already achieved.

Organic Electronics, including materials development, fabrication and test of
devices
The detailed activities included:
Molecular Electronics (Unomolecular Devices and Molecular Wires)
•
Studies on the formation and characterisation using AFM/STM of
molecular wires (MWs) self-assembled on highly oriented pyrolitic
graphite (HOPG). A detailed study was carried out on MW, prepared

PCBM (an electron acceptor) is deposited from solution or thermally
evaporated, forming a donor/acceptor system, with patterned interface,
which is used as active layer of photovoltaic cells. A study on the relation
between the cell efficiency and the details of that interface structuring
was made. The new materials are derivatives of polythiophene – the
class of polymers which has provided the most efficient OPVs, up to the
present. The introduction of the cross-linking capability aims
at
increasing the thermal stability of the OPVs as well as fabricating OPVs
with organic nanostructured interfaces by utilizing methods adapted to
the patterning of cross-linkable polymers.

been investigated in cells with «conventional» architectures for the
active layer, namely, blends and bilayers. These studies allowed to
establish comparisons between the performance of organic active layers
with nanostructured interfaces and with «conventional» architectures,

Title
Flaw Imaging in Metals by Contactless Conductivity
Funding
FCT/PTDC
Descript.
The measuring principle is based on the phenomenon whereby the
impedance of a coil generating a time-varying magnetic field
changes in the presence of a conductive material as eddy currents
are induced in the material. Therefore the idea of a contactless
electrical conductivity imaging system (CECIS) is based on a sensor
composed of two coils. One of the coils, designated the transmitter
coil, is driven by an alternating current and generates an oscillating
magnetic field that induces currents inside the object to be tested.
These induced currents are related to the conductivity distribution
of the body. Another coil, the receiver coil, measures the total
magnetic field. One component of the magnetic field is related to
the primary imposed currents and the other component is related
to the induced eddy currents. As the signal originated from deeper
voxel significantly attenuates before it reaches the receiving coil
the information gets easily corrupted by measurement noise. By
incorporating into the design a real time digital signal processor
able to perform advanced signal processing techniques it is possible
to increase significantly the range of the sensor. Two solutions are
envisaged to accumulate data either by relocating the probe
several times using a XY scanning mechanism or by using an array
of sensors, i. e., several probes in the vicinity of the object to be
tested. The mathematical basis of this methodology is developed in
two parts. In the first part, the physics of the induction system is
simulated in the forward problem either using a numerical method
like the finite element method (FEM) or an artificial intelligent
technique (ANN). The simulated system is used to preview the
correspondence between first order variations in the secondary
magnetic field to conductive perturbations in the conductive body.

A set of equations in the discrete form can be formulated: Sx=b,
where x is the unknown conductivity perturbation vector, b is the
magnetic field measurement vector and S is the sensitivity matrix.
The second part of this study is the formulation of the inverse
relation of this correspondence in order to reconstruct the
conductivity images for a three dimensional sample object: b=S x
+ y, where y represents unknown measurement noise present in
the real scenario. Since the signal from a deeper voxel is smaller
than
surface
voxel,
measurement
noise
corrupts
more
the
information from deeper voxels. However, the relation between the
magnetic
measurements
and
the
conductivity
distribution
is
nonlinear. Thus, one way to estimate the solution is to linearize the
forward problem around an initial conductivity distribution and
update the conductivity distribution using a suitable algorithm by
comparing the calculated fields with the measurements. Several
algorithms can be used to minimize the norm of ||S x - b|| when
solving for x. These algorithms must be investigated in order to
select the one that provides the best performance for the problem
to
be
evaluated.
The
mathematical
relation
between
the
conductivity distribution and the measurements is the backbone of
the imaging algorithm.

FCT/PTDC
Descript.
The work plan on this project envisages the design, preparation
and
performance
evaluation
of
useful
biodegradable
and
biocompatible dendrimers with targeted physical and chemical
properties for two defined applications: (i) in vivo smart â€œpHdrivenâ€
efficient drug nanocarriers and (ii) new chemical
sensors. The dendrimers preparation will be performed using an
306
economic, clean, and simple, one-pot procedure, where CO2 is both
used as a solvent and as a reagent (C1 feedstock). To exclude
dendrimers cytotoxicity and enhance their biodegradability urea
linkages will be incorporated in the dendrimer architecture.Another
interesting and cutting edge issue in dendrimer chemistry is that
these nanometer-sized vehicles will be incorporated within layerbylayer (LBL) films using alternating hydrogen bond interactions as
the driving force for assembly, thus enabling the incorporation of
drugs and pH-sensitive release. The unique architectural features of
dendrimers led to fairly recent developments in the field of
chemical sensing. This almost unexplored potential opens-up for
exciting opportunities that we will systematically explore: i) using
the dendrimers library without end-capping for explosives detection
ii) using perylene end-capped dendrimers for detection of metal
cations.

service delivered is compliant with road classes CE2-CE5, S- and
A- according to the standard of EN13201 That means that our
device can be installed in secondary street, commercial access,
allotment, pedestrian way, cycle track. It is compliant with all
electric standards for luminaires general requirements and tests as
well. The core element of the solution is the dimming of the lamp
depending on the environment; a set of embedded sensors
measures ambient light, temperature, current, and detect motion.
Output data of sensors is then processed by the embedded
intelligence allowing optimum regulation of light levels. The
members within the consortium have been carefully selected to
cover the entire value-chain of the project and the standardisation
as well. They are all convinced about the prosperous future for this
technology, its significant energy saving potential up to 70 %,
environmental and economical benefits and the increased level of

Title
Electric Drives Based on Matrix Converters
Funding
FCT/PTDC
Descript.
The main objective of this project is to develop an electric drive,
310
based on matrix converters, with self-diagnostic and fault-tolerant
capabilities. The drive, which will rely on the use of induction
motors and PMSMs, will allow to detect and locate any fault in the
matrix converter. After its detection, the control system of the
drive will enter in a fault-tolerant operating mode, according to
which the control strategy will be modified in order to minimize the
consequences of the fault and thus maintaining the system
running,
although
with
degraded
performance.
Besides
the
detection of faults in the matrix converter, and in the case of the
induction motor drive, the integrated diagnostic system should also
be able to detect faults in the motor, namely stator and rotor
faults, bearing faults and airgap eccentricity. The drive obtained
with these new features combines the advantages of the matrix
converter with the high reliability granted by the integrated and
fault-tolerant diagnostic/control system.

NANOPEPS
Micro-
and
Nanopatterning
of
cross-linkable
electro-active
311
polymers by spin-coating
Funding
FCT/PTDC
Descript.
This project deals with the optimization of organic electronic
devices, namely photovoltaic cells (PV), light-emitting diodes
(LEDs) and optical chemical sensors, through the provement of the
organic film morphology and functionality using a low-cost, simple,
and innovative method of patterning at the submicrometric or the
nanoscale.
Our group was recently pioneer in exploring a simple and low-cost
method to prepare patterned films at the submicrometric scale
using cross-linkable electroluminescent polymers also synthesised
in our group. In principle, the method should be scalable to large
substrates and to a broad range of different classes of conjugated
polymers. Basically, it consists on controlling the phase separation
occurring during the deposition of a solution containing a crosslinkable electro-active polymer and an «inert» polymer, on a
substrate, by spin coating. The main original characteritsic of this
approach
is
that
the
cross-linked
film
is
resistant
against
dissolution, enabling that multilayer devices may be fabricated
utilizing low cost solution techniques. This project proposes i) to
synthesise
new
cross-linkable
semiconducting
polymers
with
chemical properties designed for specific applications; ii) to extend
and to explore the patterning method to those materials to obtain
film morphologies tuned for specific applications iii) to fabricate
efficient devices based on such films. The target devices are:
- PV cells. Semiconducting polymer based-films where electrondonor and -acceptor materials are segregated forming vertical
domains (relative to the electrodes) and these are separated from
less than 20 nm represent the optimal film morphology, because it
minimizes losses in the charge generation and transport to the
electrodes
processes.
By
preparing
adequate
crosslinkable
polymers and using the referred patterning method, we aim at
tuning the column dimensions (of columnar films) or porous
312
diameter (of porous films) to obtain ideal nanostructured polymer
scaffolds,
where
the
complementary
component
(donor
or
acceptor) can afterwards be deposited filling the empty spaces.
The resultant arranjement of the two interpenetrating layers
should approach the “ideal” morphology for OPV cells.
- Optical Chemical Sensors. Fluorescent semiconducting polymers
have
shown
an
amplified
response
in
chemosensing
processes. We intend to functionalize the polymer nanopatterned
film to recognise selectively a specific target molecule which acts
as a fluorescence quencher, generating an optical sensor. Since
nanostructures have a huge surface/volume ratio, an even higher
sensitivity is expected. Examples of analytes to investigate are
fluoride, cyanide, and iodide anions resultant from toxic gases, and
metal ions such as Al3+, Pb 2+, and Ag+.
- LEDs. The most efficient organic LEDs are based on multilayered
devices comprising both charge transport layers and emissive
layers
between
the
electrodes.
Besides
showing
reasonable
efficiencies, such values are still well below the predicted maxima.
One approach for optimization, nearly unexplored so far, consists
on the use of nanopatterned hole-transport layers to increase the
contact area for charge transfer to the emissive layer. Also, there
have been reports demonstrating higher emission efficiency in
nanopatterned films, for which nanopatterning of the emissive
layer represents another approach to optimize LEDs.

The â€œSolarNHyMatâ€
project aims to foster essential progress
in the performance of organic solar cells devices by covalent
313
incorporation of acceptor molecules on the walls of mesoporous
silica nanostructured materials and encapsulation of the donor
polymers on the pores of those same silica materials. The key
scientific objectives of the â€œSolarNHyMatâ€
project will be (i)
alignment of the acceptors (on the walls) and donors (on the
pores), (ii) maximize the interfacial area and the donor:acceptor
contact, (iii) isolation of the polymer chains into nanoscale
domains leading to a confinement effect, (iv) charge stabilization
conduction along individual chains with spontaneous formation of a
graded-index waveguide, and (v) circumvent oxygen interference.
The expected results for the â€œSolarNHyMatâ€
project taking
into account the above objectives are (i) avoid phase segregation
and minimize the recombination process, (ii) improve charge
separation and increase carrierâ€™s mobility, (iii) no interchain
hopping events would be required, (iv) improve gain and reduce
loss, and (v) enhance the long term stability
