ANNUAL REPORT 2011 – KEY IT INDICATORS
1. INTRODUCTION
1.1 History
Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an
association of eigth institutions with research and development in the field of
Telecommunications:
• Instituto Superior Técnico (IST);
• Universidade de Aveiro (UA);
• Universidade de Coimbra (UC);
• Portugal Telecom Inovação, (PTIn);
• Nokia Siemens Networks S.A;
• Universidade da Beira Interior (UBI);
• Universidade do Porto (UP);
• Instituto Superior de Ciências do Trabalho e da Empresa (ISCTE-IUL).
it is organised around three sites:
• Aveiro, in the University Campus;
• Coimbra, in Site II of the University of Coimbra;
• Lisbon, in Instituto Superior Técnico.
and four delegations:
• Leiria, in the “Escola Superior de Tecnologia e Gestão” of the Leiria Polytechnic (IPL);
• Covilhã, in the University of Beira Interior (UBI);
• Porto, shared by the Faculty of Engineering (FEUP) and the Faculty of
Sciences of the University of Porto (FCUP);
• Lisboa, in (ISCTE-IUL).
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.
7
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994.
Since 1993, it activities proceed regularly.
it bylaws were first approved in 1992, modified in 1997 and modified again in 2003
and 2011. New site bylaws deriving from it bylaws were approved and
implemented in 2011.
Key developments in 2011 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 (Dr. Roland
Huber, Prof. Sir John O’Reilly and Prof. Martin Tomlinson) acting in a personal
capacity, and together with the Accounts Report (after legal certification) are
subsequently submitted to the General Assembly for approval.
The General Assembly met formally twice in 2011. The first meeting was held on
May 31st, in the Meeting Room of the Aveiro site, to discuss and approve the 2010
Annual Report and Accounts and some ammendments to it
bylaws. The second
meeting took place on December 13th, in the Meeting Room of the Aveiro site, to
discuss and approve the Work Plan and Budget for 2011.
The Research Group Coordination Committee also met twice during 2011. On the
first meeting, held on March 29, at Lezíria Park Hotel (Vila Franca de Xira), the
Draft Proposal of the 2011 Annual Report and the re-organization of the research
8
groups were discussed and received a favourable opinion. On the second meeting,
held on December 12, in the meeting room of Hotel D. Luis (Coimbra), the Work
Plan and Budget for 2012 and a proposal to create new research groups were
discussed and received a favourable opinion. The external it image was discussed
at length and the possibility of research groups having an independent web site
(within a simple set of rules) was accepted.
1.3 Highlights of 2011
In spite of the economic and financial crisis 2011 was a pretty good year for it.
Scientific output, exceeded expectations and constitutes a new record year:
• 7 books;
• 55 book chapters;
• 249 papers in international refereed scientific journals;
• 563 papers in refereed conferences, with published proceedings;
• 16 patent requests.
Fostering advanced education remained at a high level:
• 35 PhD theses, submitted and approved;
• 188 MSc theses, submitted and approved.
even if it is certain that not all MSc theses submitted and approved are recorded.
it researchers received the following IEEE distinctions
• IEEE fellowship (the fourth);
• Distinguish lecturer;
• 2011 Best paper award of the Joint Communication Society and Information
Society;
• 2011 Best paper award of the Signal Processing Society;
•
Signal Processing Society Board of Governors (in the capacity of Member at
Large).
9
FCT funding was almost normal and caused no major thumbling blocks:
• 2 M€ from IT – Laboratório Associado contract 2010 was paid in January
2011;
• 1.2 M€, corresponding to 40 % of the IT – Laboratório Associado contract
2011 was paid in two instalments (April and July);
• 510 k€ in running and concluded projects;
• 267 k€ in CIENCIA work contracts, related to 2010 expenses.
The major payment in arrears (618 k€) corresponds to the CMU project. Since it
has been underspending, in this contract FCT is in debt to only about 100 k€.
Due to prior delays in the transfer of funds from FCT, the execution periods for the
2009 and 2010 were extended to the 30 th of July 2011 and the 31st of December
2011, respectively.
The new funding rules applicable to the FCT contracts (including IT – Laboratório
Associado) foresee a upfront payment of (at least) 15 % of the approved budget.
The following payments will only be made after a minimum amount of 10 % of the
budget is reported. This new payment technique implies a much stricter treasury
control and may be damaging if FCT does not meet its promised one month
payment delay.
An interesting new point in FCT contracts is the return of the 20 % flat rate on
indirect expenses. This simplification will certainly save a lot of work and
bureaucracy.
The number of scholarships decreased slightly with respect to 2010, with the
exception of mobility fellowships, that is:
• 211 Ph.D. scholarships;
• 271 M.Sc. and B. Sc. Scholarships;
• 13 Integration in R&D fellowships;
• 2 Management of Science and Technology fellowships;
• 14 mobility fellowships associated with the ongoing CMU-Portugal Program.
10
With the exception of the Ph.D. fellowships, that were funded by FCT, all other
fellowships were funded by it.
During 2011, 150 nationally funded and 29 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 33 FP7 projects (running and selected for
funding) in addition to other 5 projects, where there was involvement of some it
researchers from the Lisbon site.
To reflect it 2011 activity some tangible objectives were defined in the Work
Programme and Budget. These objectives together with the achieved values are
given in Table 1

Achieved scientific output exceeded our forecast, in all areas, and becames a
new record except in the number of papers in conferences. It is worth noting
that the number of concluded PhD exceeded our forecast which may mean that
supervisors are improving their time required estimations.

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.
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 2011 (25 teachers).
Also in cooperation with IST, it organized visits and demonstrations for high
school pupils, involving about 1200 pupils (in 2011.

2. KEY IT INDICATORS
Human Resources
In 2011 it human resources included 808 people distributed as follows:
• 260 researchers;
• 211 PhD students;
• 300 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.

The distribution of researchers and PhD students between sites and delegations
is shown in Figure 2.2. One must bear in mind that the 13 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 (12) 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.

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.
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.

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 a significant 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. In
the following, it and CIENCIA paid researchers and their publications are not
included.

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
and Nokia Siemens Networks in Aveiro shines. Going into delegations, some
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

Antenna Analysis and Design
Work on antennas has been focused on a few main topics: antennas
for RFID and UWB systems and antennas for microwave and mm-wave
applications
with
emphasis
on
antennas
for
Ka-band
satellite
communications.
4.1.3.3
RFID and UWB Antenas
Work continued on the design of UHF RFID tag antennas and UWB
antennas
for
indoor
personal
communications
and
for
indoor
localization. New low-cost antennas for UWB indoor localization,
including
hybrid
antennas
appropriate
for
simultaneous
RFID
identification and UWB localization have been designed. A system
demonstrator and new algorithms for indoor localization enhancement
were developed.
Work continued also on near-field reader antennas for UHF-RFID
confined detection applications, including mirror embedded transparent
antennas.
Low cost UHF RFID tag antennas for near-body applications, including
interworking with body-implantable antennas have been designed,
fabricated
and
experimentally
tested.
Emerging
low-cost
tag
fabrication techniques based on ink-jet printed have been explored.
40
A source-stirred UWB radiation efficiency measurement method was
developed and results were compared with reverberation chamber
measurements and computer simulations. The method provided a
simple
cavity-based
approach
to
UWB
antenna
efficiency
measurement.
An efficient and simple UWB model of a human limb was introduced for
antenna simulations. The adequacy of the model was confirmed by
antenna measurements and an antenna prototype for wearable
systems was developed.
UWB matching resilience of dielectric loaded antennas was confirmed
and improved through measurements and by using a simple and
accurate human limb model.
4.1.3.4
Satellite related antennas
 Development of a new concept of low-cost antenna for GPS-based
positioning calibration for precision demanding applications
like
aircraft instrument landing systems in airports;
 New developments on low-cost dielectric lens-based mechanical
steerable beam antenna for Ka ground terminal satellite services;
 Design of multi-beam metamaterial-based antennas for Ka satellite
deck installation;
 Design and test of microstrip patch antenna elements and arrays for
Ka band space applications;
4.1.3.5
Other antenna related topics
Other lines of research have been pursued including:
 Analysis of antenna-user interaction through the evaluation of mutual
coupling and correlation, with emphasis on printed antennas for small
terminals;
 Design and test of an implantable compact antenna to be applied
under the human skin for medical applications;
41
 Exploration of reverberation chamber design for small antenna
efficiency measurement.
 Work was also put in the designing of special antenna structures for
vehicular communications, among vehicles and between vehicles and
infrastructures based on wireless communication technology known
as dedicated short range communications (DSRC). DSRC are in great
development with the aim of reducing traffic problems and improving
road safety. The study addressed both the development of an
antenna solution for the mobile module, usually named On-Board Unit
(OBU) and the design of an antenna for the RSU (Road Side Unit).
4.1.3.6
Circuits and systems for wireless communications
During 2011 the work devoted to wireless circuits and systems was
mainly concentrated in the design of flexible radio circuits and systems
for several applications, including: Software Defined Radio systems,
Wireless Power Transmission, Nonlinear Models and Characterization
for high speed digital buffers, Circuits for Dedicated Short Range
Communications.
4.1.3.7
New
Agile Transmitters
reconfigurable ΣΔ-based
transmitter
architecture
supporting
multichannel multimode data transmission has been designed and
validated. The high flexibility of this architecture enables a data
transmission scenario where the frequencies of the carriers and the
spectral masks can be easily changed through software, making this
agile
transmitter
interesting
for
use
in
cognitive
radio-based
applications.
Moreover injection locked class-E power amplifiers were built and
characterized in CMOS technologies. The prototypes achieved almost
30 dBm output power. An EER amplifier was designed and built. An
envelope detector and a DC-DC converter were included in the
42
architecture. The converter filter is off-chip but the rest of the system
is fully integrated.
Monolithic power combiners are being studied and designed. These
structures will be integrated with the power amplifiers. A TLT and LC
baluns and Wilkinson combiners were submitted to fabrication in CMOS
technology.
An effort was made with the internationalization. Research cooperation
with State Key Laboratory from Macau University has also started in
this field. The challenge to use new CMOS technologies with 130, 90
and 65nm channel length was achieved. Also an important investment
was made in using electromagnetic and systemic simulators.
Highly efficient wireless transmitter architectures based on a pulsed
operation were also addressed this year in complementing agile
transmitters. In that sense the study of the viability of building highly
efficient and linear carrier-burst transmitters, namely to study their
practical implementation difficulties was addressed. Beyond these
works, research was carried on the design of nonlinear behavioral
models for telecommunication sub-systems and devices, and their use
in digital pre-distortion linearization. The application of these studies
has been directed to both conventional Cartesian and polar wireless
transmitters, namely for current-mode and switched-mode RF power
amplifiers and wireless transmitter systems.
A buck switch mode converter at 100MHz was fabricated and tested in
a 180nm CMOS, to supply a Class-D PA. A 5V to 1.8V buck converter
at 100MHz was also designed and sent for fabrication, using a cascode
topology for the power circuit switches, in a 180nm CMOS. The study
and design of a fully integrated buck switch mode converter was
started. The idea is to increase switching frequencies up to hundreds of
MHz (>300), in order to integrate the LC filter. Preliminary results
indicate the viability of the proposal.
A strong effort was put on the study of its nonlinear impairments to the
overall
linearity
and
efficiency.
Other
technologies
have
been
approached as self-oscillating power amplifiers that constitute an
innovative architecture that has theoretical 100% efficient operation
43
under linear operation. The end of this year also marked the beginning
of a research project in collaboration with an International Company
aiming to study distortion generation mechanisms in Doherty power
amplifiers.
4.1.3.8
Agile Receivers
This year some innovative ideas for increased dynamic range and
bandwidth for software defined radio receivers were also explored,
including the study of nonlinear behaviors, which is fundamental for
the increase of the dynamic range.
This was complemented with theoretical evaluation of polynomial
behavioral model simplifications using circuit level physical knowledge
and general Volterra series calculations, and also combined with the
study of Predistortion theoretical limits. The goal of this work is to
calculate the maximum power efficiency of an amplifier with and
without the use of a predistorter in order to determine the maximum
profit that can be obtained using this technique.
Study of low noise amplifiers was also pursued this year by designing a
simple version of a SiGe active inductor with less transistors and
independent voltage control of inductance and quality factor. A 30GHz
LNA with CMOS technology was designed and sent for fabrication.
4.1.3.9
Signal Integrity in Devices
Advances in the design of new enhanced behavioral models for
accurate simulation of Input/Output buffers of IC circuits were
conducted. These new models extend the accuracy of previous models
and
can
incorporate
the
characterization
of
additional
physical
phenomena within the IC chip, such as bouncing of the power and
ground rails. Additionally, such models aimed also at very high
simulation efficiency. This is very important for proceeding with robust
estimation, through simulation (before prototyping), of signal integrity
of complex IC design devices, such as in System-in-Package or
System-on-Chip architectures.
44
4.1.3.10
Short Range Communications Systems
Work continued on the 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 follows the IEEE 802.11.a whenever
necessary. Following the current 802.11p recommendations, basic
functionalities are being implemented in order to comply with the
identified applications and scenarios.
4.1.3.11
Wireless Power Transmission
This year a new area emerged on the design of better and improved
circuits for wireless power transmission: the effort was put on the
design of RF-DC converters and on the design of highly
efficient
waveforms for maximizing the range of these circuits.
4.1.3.12
Earth-Satellite propagation and instrumentation
Work in this sub-area included the characterization of propagation
through
vegetation
as
well
as
fundamental
research
on
electromagnetics of complex media with possible applications to
antennas and guided wave structures. Studies on EM exposure
assessment have also been pursued.
4.1.3.13
Radiowave propagation modelling
A time varying dRET simulator is being developed to study the effects
of vegetation in radiowave propagation.
A ray tracing model is being developed with MIMO capabilities for the
extraction of doubly selective channel models.

is being developed for propagation studies. A measurement system is
45
also being developed that enables DVB-T trials, both at radio and link
levels in addition to video and channel coding optimizations.
Building scattering mechanisms are being studied for millimeter wave
frequencies (e.g. 61 GHz).
Channel models are being developed for Body Area Networks;
4.1.3.14

media was pursued. A detailed study of mode characteristics in several
indefinite waveguides was carried and some uncommon properties as
coexistence of forward and backward waves and contra directional
coupling have been analyzed.
4.1.3.15
Transmission and Receiving Systems
These studies were mainly concentrated on 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.
4.1.3.16
Mobile Communications
The achievements for mobile communications focused on several
aspects of present and future radio systems including modulation,
coding, equalization, channel estimation and synchronization. Most of
these studies were based on an analytical approach.
Following the work from previous years, studies were performed on
interference coordination and power saving techniques for LTEAdvanced. Study of capacity enhancement of wireless communications
systems
using
multiuser

Architectures for Wireless Systems
Future wireless systems should fulfill several goals, among which:
provision of true broadband wireless access and enhanced system
capacity when compared with current 3rd Generation (3G) networks.
To achieve a generalized deployment, all technical solutions are
constrained by capital and operational expenditures and should provide
the required flexibility to allow upgradeability and reconfigurability.
This requires the definition of novel architectures and appropriate
algorithms / protocols. At the architecture level work was focused on
distributed antenna systems (DAS) and cooperative diversity / relaying
systems. Work topics included:


Scheduling algorithms for distributed antenna systems;

System capacity evaluation;

Development of system level simulators to support the
research.
Work
addressed
also

optimization
of
combinations of physical and network techniques based on intercell
and wireless intracell cooperation in a cellular enhanced architecture to
50
increase network capacity and coverage, improve flexibility, robustness
and fairness. Specific aspects dealt with recently are:

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 (SingleCarrier 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 multi-antennas
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, codebook and receiver
design and optimization, as well as researchers working on propagation
53
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 non-linear 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 time-dispersive 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 also consider STF codebook designs and receiver designs exploiting
the knowledge about short and long term channel statistics.

Title
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
investigate, develop and demonstrate how cognition and cooperative
strategies can be extended to decrease the overall energy consumption
56
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, 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:
57
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 OFDM-based
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
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
58
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
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 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
61
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
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 crosslayering 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
71
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 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.

OPPORTUNISTIC-CR
Opportunistic
Aggregation
of
Spectrum
and
Cognitive
Radios:
Consequences on Public Policies
Funding
FCT/PTDC
Descript.
Networks
of
the
future
are
tending
towards
a
diverse
wireless
networking world, where scenarios define that the end-user will be able
to attain any service, at any time on effectively any network that is
optimized for the application at hand resulting in “flexibility and choice”
to enhance the quality of life of the individual, in a context of seamless
interoperability and cognitive radio between network operators and
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
74
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 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).

This

is
aimed
at
the
design

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

also

for
the
nonlinearities of the AM and PM modulator, of the RF PA and of the

filter.
Furthermore,
the
complex
stability and ultimate injection locked behavior analysis of these SOPA
80
structures (which is a determinant problem for any highly nonlinear
dynamic feedback loop) will be thoroughly performed through bifurcation
analysis across input envelope 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 self-oscillating clock and a RF
carrier - of three disparate time-scales - exciting strongly nonlinear lowfrequency 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) system-level 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 new simulation method dedicated to device-level
simulation of SOPA circuits (or circuits that suffer from similar multirate
problems).

Cognitive Radios Adaptable Wireless Transceivers

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
implementations,

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
82
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

would
facilitate fastest possible uptake and proliferation of CR/SDR. The need
for this Action has been supported by European regulators in the
European Conference of Postal and Telecommunications Administrations
(CEPT). They stated willingness to use the results of the Action in their
work on developing the harmonised European regulatory regime for
84
CR/SDR. Very conveniently, proposals elaborated by the Action could
also be used as a part of European contributions to the forthcoming
World Radiocommunications Conference in 2012, which has CR/SDR
regulatory policy on its agenda.
Working towards that objective, TERRA will structure its activities in the
following clusters: research into development of plausible deployment
scenarios
for
CR/SDR,
based
on
results
of
current
and
future
technological R&D activities, research into what regulations would be
technically feasible, research into what regulatory regime would be
economically attractive, research into overall impact assessment and
societal benefits of developed regulatory scenarios.

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 dynamic transfer matrix method (TMM) has been numerically implemented in
non-conventional DFB laser structures. Preliminary dynamic results concerning
the transient behaviour of the output power and the emitted wavelength of an
optimized asymmetric 3PS-DFB laser structure have been obtained.
The frequency response of dual depletion InGaAs/InP PIN photodiodes was
investigated in detail. The location of the drift region relative to the n and p
contacts, the direction of the incident light and the bias voltage were taken into
account in the numerical simulator model. The bandwidth results from the
interplay between the transit time, in the drift and absorption region, and the
capacitive effects and, for short devices, it is mostly independent of bias voltage
because the capacitive effects are dominant. The bandwidth may be optimized by
123
an adequate choice of the absorption and drift region lengths and bias voltage,
and takes larger values than for the conventional PIN structure.
New techniques and new innovative devices based on fiber Bragg gratings (FBG)
in
micro-structured
plastic
optical
fibers
were
developed
for
optical
communications and sensing applications.
Carbon allotropic (diamond and graphene) coated optical fiber devices were
studied for sensing and communications applications.
Optical fiber sensors were developed for: monitoring human joint angles,
measuring water turbidity, hemodynamic assessment, monitoring the Madeira
wine vinification process, measurement of refractive index and bending, viscosity
and anion recognition. This work included novel plastic fiber sensors for refractive
index and bending measurement. A fiber monitoring system, based on fiber
sensors and wireless transmission was also optimized and developed.
Some strategies were studied to mitigate the fiber fuse effect. This effect can
have a deteriorating impact in practical cases where the optical power carried by
an optical fiber is greater than a certain threshold. Power transmission over
optical fiber was also studied and some experimental work performed.
The following devices were optimized and developed for some specific
functionality in optical communication systems and networks:
- passive devices (Y-branch splitter and MZ modulators) for passive optical
networks, based on sol-gel technologies;
- an acoustic wave generator was used for optical fibers to be used in tunable
filters;
- optical filters for radio over fiber;
- a novel photonic true-time delay beamforming system for phased array
antennas. The system relies on tunable delay lines which are based on MachZehnder delay interferometers (MZDIs) with tunable coupling ratio;
In the area of all optical signal processing, we showed that all-optical polarization
control based on Raman scattering can be obtained over a wavelength range of
60 nm. The efficiency of the pulling process is higher close to the Raman gain
peak. For shorter and longer wavelengths, higher pump powers are required in
order to assure maximum efficiencies. Such polarization controllers provide a
124
very fast response time, overcoming an important drawback of polarization
control schemes based on optoelectronic elements.
We also studied the generation of two idler waves inside a high birefringent (HiBi)
optical fiber through three four-wave mixing (FWM) processes. The coupledequations for the field amplitudes were derived and analytically solved, in the copolarized and orthogonal polarization schemes. Results show that the stimulated
Raman scattering does not change the efficiency of the idler wave generation in
the co-polarized scheme, whereas in the orthogonal polarization scheme the
nonlinear process decreases the efficiency of the four-wave mixing processes.
Work on all-optical signal processing for high bit rate optical networks covered the
following aspects: advanced techniques for all-optical routing, tunable dispersion
compensation, optical filtering, pulse shaping, clock recovery, optical code
division multiplexing and regeneration. In the area of all-optical processing for
ultra-high speed systems, we have carried out some work in deriving latching
structures for implementation of all-optical memories. Work on all optical signal
processing with SOAs has focused on the set-up of a lab experiment for
evaluation of static RAM. The set-up is ready and measurements should start in
the first quarter of 2012.
An all-optical packet monitoring technique was derived and is now being
simulated. Work on the experimental demonstration of this technique has started
in order to give some more capabilities to the physical layer.
4.2.3.4
Optical communications systems
In the area of equalization in high-bit rate optical communications, we proposed a
non-iterative digital backward propagation technique, based on an inverse
modified Volterra series transfer function to post-compensate linear and nonlinear
transmission impairments in the presence of optical noise. Our compensation
algorithm is able to surpass the maximum accuracy obtained with a symmetric
split-step Fourier method, enabling us to increase the nonlinear tolerance by
approximately 2 dB. Also some DSP algorithms were developed for coherent
receiver applications. In addition, the study of techniques for impairment
compensation
in
coherent
communication
systems
based
on
memory
polynomials was initiated.
125
Work was carried out in the area of RoF transmission using directly modulated
lasers. Studies of RF propagation over fiber included TDT, satellite (video) and
multi-band OFDM-UWB radio signal transmission along long-reach PONs. These
studies included simulation and experimental evaluation. Experimental evaluation
concentrated on video over fiber (CWDM and DWDM) scenarios, compensation
of non-linear laser response, amplification topologies, and transmission
impairments. Research on RoF systems also focused on photonic techniques for
generation of microwave and millimeter wave sub-carriers.
The study of GPON standards and evolution to NGPON involved topologies and
modulation formats. Work was also carried out regarding scenarios and
technologies to support XGPON (extended reach GPON).
Some efforts were dedicated to the study of performance degradation of optical
single sideband signals in the case of direct detection.
The topic of optical transmission systems based on mode group diversity was
identified as having a large potential. A digital simulator for the propagation in
multimode fibers was developed, which takes into account modal coupling at fiber
imperfections and splices between single mode and multimode fibers. A nonlinear
model for pulse propagation in multimode fibers with reduced radius, which
supports a small number of modes, has also been developed.
In the area of quantum cryptography, we have derived novel analytical
expressions to estimate the quantum bit-error rate (QBER), in quantum key
distribution (QKD) systems based on polarization encoding with single-photons
state of polarization (SOP). Such expressions are in agreement with experimental
results. We have also shown that the de-correlation between the reference and
data signals is the fundamental impairment in the implementation of WDM based
SOP control schemes. This makes mandatory the use of low PMD fibers in order
to achieve large distances with a low QBER.
The search for new CDMA codes has been pursued, by exploring their
applicability in access networks with coherent modulation and detection.
A moment generating function of the signal at the output of direct-detection
optically pre-amplified OFDM receiver, relying on the uncorrelation of signal
samples at the receiver fast Fourier transform block input, was proposed to
126
assess the performance of direct detection OFDM receivers. The development of
an accurate moment generating function that takes into account the correlation
between the signal samples at the receiver fast Fourier transform block input for
the same kind of receivers was initiated.
A photonic analog-to-digital conversion (Ph-ADC) structure based on wavelength
division multiplexing (WDM) was investigated, and its performance was
compared with the performance of the Ph-ADC photonic structure based on time
division multiplexing.
4.2.3.5
Optical networking
The work on access networks has continued, with special emphasis on next
generation PONs and their convergence/integration with MANs.
Wired-wireless converged next generation optical access networks were
investigated. The coexistence of multi-format OFDM-based signals (custom
OFDM signal bearing Gigabit Ethernet data, WiMAX, LTE, UWB sub-bands) in
long-reach PONs (LR-PONs) using directly modulated lasers and externally
modulated lasers was studied numerically and experimentally. Schemes for
centralized broadband impairment compensation at the central office of such
multiservices/signals LR-PONs were proposed and assessed experimentally
considering single wavelength and multi-wavelength transmission. Linearization
improvement of directly and externally modulated LR-PONs achieved by using
digital pre-distortion of those multi-octave OFDM-based signals was investigated
numerically and experimentally.
Several achievements were obtained in the area of FTTH. António Teixeira has
been appointed IEEE and FSAN/ITU representative for next generation PON's.
Marek Hajduczenia also participates actively as editor in the standardization
activities of IEEE 802.3 (focus on the physical layer of EPON systems) and IEEE
1904.1 (focus on logical layer and service layer interoperability of EPON systems)
as well as in major IEEE projects, namely P802.3bf (focused on development of
standard interfaces for all types of Ethernet physical layers; chief editor) and
DOCSIS (Evolution of Cable Networks). Therefore, several contributions have
been made as regards standards organizations.
127
Raman amplification was studied in the context of PON applications and optical
powering of remote nodes was demonstrated. Raman amplification was also
analyzed for optical burst switched networks and comparisons (experimentally
and by simulation) were made with other amplification technologies (EDFAs and
SOAs).
In the area of RoF systems, several techniques were investigated for
simultaneous transport of different services in the baseband and in several
microwave and millimeter wave bands, and for the optimum operating conditions
for supporting multiple radio channels over a SCM-based distributed antenna
system.
In the case of optical network dimensioning, we developed a genetic algorithm for
the topological design of survivable optical transport networks, with minimum
capital expenditure. Using the developed genetic algorithm, we could obtain nearoptimal topologies in a short time. The quality of the obtained solutions was
assessed using an integer linear programming model. Results obtained using real
telecommunications networks show that by using an initial population that
resembles real optical transport networks a good convergence is achieved.
Work on optical burst-switched networks continued in 2011. Strategies to deal
with quality-of-service differentiation in OBS networks have been proposed.
An optimization framework for designing optical transport networks
in
environments with mixed line rate demands (40 Gb/s and 100 Gb/s), aiming at
the minimization of the network cost, by taking into account aspects such as
grooming, virtual concatenation and regenerator placement has been continued.
A planning tool to design multi-stage passive optical networks, which includes the
proposal of an integer linear programming model and an efficient heuristic to deal
with the optimization problem, has been developed.
In the area of physical layer impairments in optical networks, the influence of
crosstalk-crosstalk beat noise on optical DPSK systems performance was
investigated, the behavior of eigen-functions and eigen-vectors in those systems
was studied, and the impact of in-band crosstalk in the performance of those
systems was evaluated using Monte Carlo simulation.

Title
Steering of light in nonlinear waveguides with resonant interactions
Funding
FCT/PTDC
Descript.
This project aims to study the steering of light in different nonlinear
systems with internal resonances. Nowadays such systems attract a
great deal of attention because modern technologies allow to produce
devices where internal resonant interactions between light and
material excitations result in huge optical nonlinearities, providing a
rich plethora of nonlinear effects at relatively low power. These huge
nonlinearities and the flexibility of physical parameters make such
devices very attractive for different practical applications, including
guidance of light, information processing, and generation of new
frequencies. In addition, such systems constitute laboratories to study
fundamental nonlinear phenomena. This project addresses several
kinds of physical systems and devices. We consider hollow-core
photonic crystal fibers filled with gases of multi-level atoms whose
resonant frequencies match the frequency band guided through the
fiber. In these systems, the matter-light interactions are not only
strong
because
of
their
resonant
nature,
but
are
also
easily
manageable through the control of the coupling field on the other
hand. Systematic investigation of the nonlinear dynamics will be
undertook, starting from the study of the propagation of the
continuous radiation in simple geometries, but also looking into the
dynamics of short pulses, to the formation of optical solitons, and to
their mutual interactions in more sophisticated geometries, like
coupled waveguides, networks of waveguides, couplers, etc.. The
formation and stability of solitons, representing coupled states of light
and matter, i.e. a kind of polaritons, is expected to be strongly
affected by the waveguide characteristics and by the material
dispersion of the media. Hence, it will be explored how the
propagation of short pulses can be steered by the slowly varying
quasi-continuous waves and by additional short pulses. Effective
132
models describing linear and nonlinear effects by taking into account
the quantum mechanical description of the interactions will be
developed, giving special attention to the impact in the propagation of
solitons of dissipation, particularly dissipation due to spontaneous
emission from the excited states of the multilevel atoms, material
losses and imperfect guidance of the light. When dissipation is weak
enough we can speak about quasi-solitons propagating at long
distances, whereas in the quantum regime, when dissipation is strong
enough, we can expect manifestations of the Zeno effect. We also
investigate how the dissipation affects not only the maximum
propagation distance of the solitons, but also their shapes and
stability. Technologically it is possible to manufacture a multi-core
fiber filled with active gases. For these fibers, it is important to study
the interaction between the pulses propagating in the neighbouring
cores and find out the conditions of effective energy transference
between modes. We plan to address this problem analytically and by
extensive numerical simulations. We also investigate semiconductor
microstructured systems, which are another important kind of the
waveguiding systems produced on semiconductor chips. The main
advantages of these systems are their small sizes and the possibility
to pump them by external continuous sources of the light. Cavity
solitons can survive in these systems until the pump is switched off.
The bright and dark solitons can be controlled by the pump and by
weak control signals. This type of systems can be used as optical
memories and for information processing, as well as, on the
generation of new frequencies. We also consider systems consisting of
a semiconductor thin film which serve as planar waveguide for the
light and can be pumped by a coherent light due of imperfect
guidance. The resonant nonlinearity arises from stimulating excitons
with resonant frequency coinciding with the cut-off frequency of the
planar waveguide. Consequently, it is possible to excite quasiparticles
with very low group velocities, commonly known as polaritons and
resulting
from
the
resonant
coupling
of
light
and
mater excitations, which provides very strong nonlinearities. This
allows
the
formation
of
resting
or
slow
moving
localized
133
optical
structures

pumping
powers.
Meta-material waveguiding systems consisting of weakly nonlinear
dielectric films with build in metallic nanoparticles are also considered.
The nanoparticles provide polariton resonances playing a role similar
to the exciton resonances. These systems will be modelled rigorously,
starting from basic quantum-mechanical theory. We will investigate
the dynamics of the solitons in detail using analytical and numerical
methods.
The
possibility
of
controlling
the
solitons
by
weak
perturbations of the pump, as well as, the resonant mutual interaction
between cavity solitons and between the solitons and quasi-linear
waves will also be investigated.

In-band crosstalk in optical communications systems with differential
direct detection
Funding
IT
Descript.
This project is within the optical communication networks area. In
particular, in the area that studies the physical constraints in optical
networks.
One of the most severe limitations in the network physical layer is
crosstalk. This phenomenon has its origin, primarily, in the imperfect
isolation
of
optical
components,
such
as
optical
switches,
multiplexers, and demultiplexers, that are key components in the
design of an optical node. The type of crosstalk that causes the higher
degradation to the system performance is the in-band crosstalk, in
which the interfering (crosstalk) signals and the selected signal,
despite coming from distinct optical sources, have the same nominal
wavelength.
136
The main objectives of this project are:
* Develop a formalism to evaluate the impact of in-band crosstalk in
optical DQPSK systems.
* Evaluate the impact of in-band crosstalk in a DPSK and DQPSK
systems when the signal propagates through an optical network. Each
optical node is formed by an optical switching architecture, optical
amplifiers, optical filters, and possibly wavelength converters.
* Implement Monte Carlo (MC) simulation to study the impact of ASE
noise and in-band crosstalk on the performance of DPSK and DQPSK
systems and confirm the analytical results.
* Implement the multicanonical Monte Carlo (MMC) method to
simulate the tails of the probability density function of the decision
variable and to obtain lower values of the bit error rate (BER) than in
the MC standard procedure.
* Evaluate by simulation the impact of in-band crosstalk in optical
networks with DPSK and DQPSK signals, for a rigorous model of the
optical node and validate the analytical tool developed for this case.

Future high-speed optical communication systems will inevitably rely
on new enabling technologies such as advanced modulation formats,
coherent detection and receiver-side digital signal processing. In order

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.

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 eye-strain 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
single aperture ultra-high definition 3D Holoscopic imaging camera will
be constructed which will permit live capture of 3D content. For the
183
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
complex than monoscopic video and the need for low complexity
decoding
is
higher
because
of
limited
battery
life
and
computational resources in portable decoders.

Title
3D Video Quality Monitor
Funding
IT
Descript.
The project is focussed on research and development of 3D video
perceptual quality monitoring in error prone networks, such as the near
future 3DTV services over IP or DVB networks. The challenge is to
establish a set of (Quality of Experience) QoE metrics and their
relationship with objective measurements that affect the overall QoE.
These metrics are computed from a combination of transport network
layer information, quality features of 3D video signal and coding
parameters embedded in compressed streams. The project seeks to
investigate No-Reference (NR) methods such that blind 3D quality
assessment can be carried out at any point of the delivery chain
including the receiving terminal. Such an approach is rather more
challenging than Full-Reference (FR) or even Reduced-Reference (RR)
methods, where either the original signal or partial information about it
is available.

Affective Mouse
Title
Affective Mouse
Funding
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
185
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.

Title
Activity Recognition and Object Tracking Based on Multiple Models
Funding
FCT/PTDC
Descript.
There are hundreds of cameras deployed in public places (e.g., streets,
shopping malls, airports). However, only a small fraction of the cameras
outputs (<5%) is regularly observed by humans. Most of the video
information is stored or destroyed without being watched or processed.
This means that current surveillance systems are not able to detect
abnormal events in real time. A large effort has been recently done to
develop algorithms to track objects (persons, vehicles) in
video
sequences and to recognize activities and unusual behaviors. Despite
this effort, the problem is still far from being solved. Most of the current
techniques only consider isolated persons and try to characterize the
activity based on the trajectory in the video sequence or using shape
features (silhouette, gait, gestures). Shape parameters may be useful
when the camera is close to the object being observed, but trajectories
are more important if the object is far from the camera. In the case of
small/far objects, the surveillance system should be able to learn typical
trajectories from the video signal and to compare new trajectories with
the learned ones in order to recognize activities and detect unusual
events. This can be done by clustering the observed trajectories into a
set of typical clusters, each characterized by a “mean” trajectory or by a
statistical model. The comparison of trajectories is not a simple task.
Some methods involve the temporal alignment of sequences (e.g., using
dynamic time warping). Other methods avoid explicit alignment by
resorting to generative models (e.g., dynamic Bayesian networks). In
186
the latter approach, checking if some new trajectory is well described by
a
model
corresponds
to
computing
its
likelihood
under
that
model These generative models, however, are difficult to train and non
intuitive since their structure and parameters have no physical meaning.
This project will develop a new representation for activity recognition
which tries to overcome some of the previous difficulties. We assume
that the (person, vehicle, animal) trajectory is generated by a set of
space-varying
velocity
fields
learned
from
the
video
data. Different velocity fields correspond to different motion regimes.
Consider, for example, a cross between two streets. We may have one
velocity field describing the pedestrian motion in the first street and a
second velocity field in the second street. Switching between the driving
fields is possible and the switching probabilities are also space-varying
(they depend on the person position in the scene); it’s possible to switch
at the cross, but not far from it. Therefore, switching is described by a
field of space-varying stochastic matrices. This model will be learned
from a set of observed trajectories using the expectation-maximization
(EM) algorithm. This seems to be a natural choice, since we do not know
which velocity field is driving the motion (active field); these active field
labels are thus treated as missing data. The estimation of the spacevarying
matrices
will
be
performed
in
an
information
theoretic
framework using tools from differential geometry (natural gradient
based on Riemaniann metric). This will be done in an unsupervised way.
The number of models, the velocity fields and the field of switching
matrices will all be learned from unlabeled data (video sequences). The
proposed model is intuitive and easily understandable/ interpretable
since each velocity field can be observed and describes a different type
of motion in the scene. This information can be used by the manager of
the infrastructure to characterize the typical ways in which people move
in that place. Furthermore, it is also a good starting point for activity
recognition
based
on
the
sequence
of
active
models
(switching
sequence) and the computation of the sequence probability in order to
detect abnormal behaviors. We also propose to develop an extension of
the activity recognition system to the case of pairs of interacting
pedestrians or even larger groups. The movement of each pedestrian will
187
also be modeled using the set of velocity fields as before. The
dependence between different pedestrians will have to be modeled since
we can no longer assume that they are independent. We will model the
pairs (triplets, etc.) of labels in order to describe common activities
(e.g., walking together, pursuing). Although the project is focused on
human activity recognition, the proposed methods can also be applied in
other contexts (e.g., surveillance of highways, analysis of the motion of
isolated animals of groups of animals). The project team has worked
together in the past and that work led to several joint publications. It
includes 4 PhD researchers from 3 research institutes and it will also
involve post-graduate students. The team has significant experience in
all the the topics involved in the project: surveillance, object tracking,
pattern recognition, computer vision, dynamical systems, and differential
geometry.

converter from phonemes to visemes. In the case of text input, a
synthesizer is used to create both the audio (speech) and the sequence
of visemes. 3D face animations, created after the sequence of visemes,
need to run on browser to allow the development of rich and interactive

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
traditional biometric systems. The additional consideration of multimodal

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 in-network
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 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

languages with self-configuration and distributed update capabilities. We
propose to develop specifically tailored high level idioms for sensor

Cryptography
Funding
FCT-PTDC
Descript.
This project addresses the problem of correct symbolic abstractions of
cryptographic primitives for the purpose of symbolic, automated 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 CSP-model 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
194
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, 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
195
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 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

The grand objective of the research project DEWICOS: Design of Next

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 low-density parity-check (LDPC) codes. In fact,
these powerful techniques are now gradually being incorporated into
wireless

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
198
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 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
199
key research groups from the reputable Instituto de Telecomunicações,
gathers considerable expertise in a wide range of complementary topics
such as information theory, estimation and detection theory and
communications systems and networks, all of which are necessary to
meet both the theoretical and practical challenges of this research. Highlevel publishable (and possibly patentable) results are expectable

Aberrant Crypt Foci and Human Colorectal Polyps : mathematical
modelling and endoscopic image processing.
Funding
Descript.
FCT, UT Austin
Colon cancer is a type of cancer that forms in the large intestine (colon)
or the rectum (end of the colon). Because it often affects both areas it is
frequently referred to as Colorectal Cancer (CRC). It is one of the most
frequent malignant tumors in the world. In Portugal, it is ranked first in
terms of mortality among the five major cancer types (lung, breast,
colon, stomach and prostate). Unlike most other malignancies, it is
possible to prevent colorectal cancer. This is due to the long period of
time elapsed between the appearance of a polyp and the eclosion of the
carcinoma, which allows the detection and removal of the benign lesion.
The most usual and clinically important polyps are adenomatous polyps
(or adenomas), which are common in adults above the age of fifty years.
According to international medical guidelines, early detection and
removal
of
adenomatous
polyps
can
prevent
CRC
and
significantly improve the chance of survival. However, many public
health issues related to screening of adenomatous polyps, as the
periodicity and type of endoscopic evaluations, and the age of first
evaluation, are still under discussion, and there is not an agreement
204
about the screening programs. In this context, Aberrant Crypt Foci (ACF)
may have a crucial and determinant role. These are clusters of aberrant
(deviant from normal) crypts (small pits, which are compartments of
cells, in the colon epithelium) that are thought to be the precursors of
colorectal cancer. In fact, according to endoscopic studies and animals´
experiments, ACF precede the eclosion of adenomas. Thus if this claim is
proved, it means ACF must be considered part of the adenomacarcinoma sequence. This proposed project focuses in the mathematical
modelling and endoscopic imaging processing of ACF and polyps. It
requires
interdisciplinary
interactions
and
close
collaboration
in
complementary areas. The main goal is to assist medical doctors in
terms of the diagnosis, the prevention and the treatment of colorectal
cancer. For the modelling part, our intention is to utilize multiscale
methods, which involve partial differential equations and level set
methods, to simulate the dynamics and shape of ACF and polyps
populations.
Mathematical
simulations
will
be
compared
with
experimental and clinical results. Such a comparison will lead to critical
assessment of the models assumptions and to introduce suitable
changes for their enhancement. We believe these models will be able to
reproduce some particular aspects of the behavior of the human colon,
and to reveal processes/mechanisms that would be impossible to reach
with real-life experiments. They will provide some insight into ACF and
polyps dynamics/behavior and consequently into CRC carcinogenesis.
For the image processing part our aim is to develop computerized and
fast algorithms to identify and assess the ACF and polyps patterns,
captured in vivo by endoscopy. In particular, PDE (partial differential
equation) and variational based image processing methods will be
applied. The current methods employed for assessing the ACF and
polyps patterns are somewhat subjective. They rely on direct medical
observation only and are not standardized nor automated. It is desirable
to have a reliable computerized method capable of identifying the ACF´s
external boundaries and the crypts´ orifices in their interiors, as well as,
the polyps´ patterns (size, morphology, color, surface, location). In this
proposed project, the ACF´s images are obtained by magnification
chromoscopic colonoscopy, with a fexible endoscope, whereas the
205
polyps´ images are acquired with a colon capsule endoscope. This latter
is a very recent noninvasive tool for colonic evaluation, and consists of a
microdevice, which is ingested by a patient and films the interior of the
colon wall. The main advantages of such image processing algorithms
would be to support the clinical reading and analysis, to improve
diagnostic accuracy, to help to standardize colonic crypt and polyp
pattern assessment, and to reduce the time needed for analyzing the
huge
amount
of
endoscopic
images.
In
this
way,
these
algorithms would facilitate and speed up screening methods towards the
CRC prevention. The study of these research topics started in January
2007 at the Mathematical Department of the University of Coimbra (see
http://www.mat.uc.pt/
cmuc/lcm/endoscopic.html),
with
the
collaboration of medical doctors from the Faculty of Medicine of the
University of Coimbra and the University Hospital of Coimbra. Later on,
in October 2007, we initiated a collaboration with the University of Texas
at Austin (UT Austin), in the Institute for Computational Engineering and
Sciences (ICES), involving Omar Ghattas, Georg Stadler, Chandrajit
Bajaj, Bjorn Engquist and Richard Tsai. These researchers are now

The main goal is to pursue interdisciplinary research involving muscle
physiology, biomechanics and neuromuscular control. The actual focus is
to conduct research for the evaluation of biomechanical load on the
musculoskeletal system. Our underlying hypothesis is that the increasing
208
of the amount of exercise can positively influence biological tissue
morphology
and
functional
mechanical
properties.
Nevertheless,
excessive loading, both in intensity as well as frequency and volume, can
be associated to acute and chronic musculoskeletal impairments. We aim
to study the effect of specific mechanical loads in the musculoskeletal
system, with special emphasis in the muscle-tendon complex, and the
cartilage.
The
study
will
be
centered
on
architectural/structural,
functional and neuromuscular chronic and acute changes associated to
the mechanical load supported while the body is undergoing exercise
routines,
of
moderate
to
high

cyclic
loading.
To accomplish the study of the biological tissue chronic and acute
adaptations to cyclic mechanical loading two complementary approaches
will be used: (1) in vivo imaging methodologies (magnetic resonance
imaging - MRI - and ultrasonography - US); (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 muscle-tendon 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

analyzed
applying

techniques
for
exploratory data analysis, crossing it with the different types of

MUlti-view distributed coding for VIsual Sensor networks
Funding
FCT/PTDC
Descript.
Distributed video coding (DVC) is a compression paradigm based on two
key Information Theory results from the 70s: the Slepian-Wolf and the
Wyner-Ziv theorems. Contrary to the available predictive video codecs,
DVC codecs exploit the source statistics at the decoder providing
functional benefits such as: 1) flexible distribution of the computational
complexity between encoder and decoder; 2) in-built robustness to
channel losses; 3) exploitation of Inter-view data correlation at the
decoder.
These functional benefits are very important for visual sensor networks,
a network of wireless low-power video camera nodes, used for a wide
range of applications such as surveillance, monitoring of remote areas or
tele-presence systems. Visual sensor networks are characterized by: 1)
Inter-view correlation between camera nodes with overlapped views; 2)
up-link communication between many encoders (one at each camera
node) to a few decoders; 3) independent compression of each view,
since collaboration between cameras is difficult to implement or rather
inefficient.
Due to these characteristics, it is not efficient (or possible) to compress
each captured view at a central node with the typical predictive
approach, e.g. using the recent multi-view video coding H.264/MVC
(Multi-view Video Coding) standard, since it implies to exploit spatial,
temporal and Inter-view correlations at a rather high complexity
encoder.
The
architectural
distributed
benefit
since
coding

approach
does
not
provides
require
a
any
significant
Inter-camera
communication to explore the Inter-view correlation while the predictive
approach requires the availability of all views at some central encoding
location, forcing communication between cameras. This project will
advance state-of-the-art by developing competitive multi-view DVC
solutions
for
visual
sensor
networks,
notably
by
proposing:
1. Side information (SI) creation and correlation noised modeling: To
212
fully exploit the potential of the multi-view distributed video coding
paradigm, high quality side information (an estimation of the source
created at the decoder) must be created by (jointly) exploiting temporal
and Inter-view correlations. In this case, solutions that combine
temporal and Inter-view SI estimators by using preliminary decoded data
as helper information will be proposed. In addition, correlation noise
models capturing the statistical correlation between the side information
(available
at
the
decoder)
and
the
source
(available
at
the
encoder) will also be proposed along with the estimation of the relevant
parameters.
2. Hybrid predictive-distributed video coding: The combination of
predictive coding techniques, to exploit the temporal correlation, with
distributed coding techniques, to exploit the Inter-view correlation, may
be a successful “cocktail” to obtain improved rate-distortion (RD)
performance. This approach was never exploited before (as much as the
authors know) and will require to reinvent popular coding techniques at
both encoder and decoder. In this case, it is also expected to obtain
error resilience improvements, which is quite important in this type of
error-prone networks (typically wireless).

The main purpose of this project is to address the feasibility of an
automated
system
that
performs
covert
and
reliable
biometric
recognition, using the iris as single trait. Obviously, this type of biometric
recognition is extremely ambitious and 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 community as ‘’the grand-
challenge’’ (e.g., ''Biometrics: a grand-challenge'', A.K. Jain), due to the
implications that they can have in modern societies.

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, 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 finetuning 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
215
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 root-causes 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 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,

Machine
Learning

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 CMU-Portugal 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

Over the past few years, we have witnessed tremendous advances in the

several

etc) and possess signi cant embedded processing and low-range wireless

(WSN)
where
large

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

and

and

smart

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
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
218
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
a formidable optimization challenge. Indeed,
sensors
represents
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 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 (non219
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
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
220
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
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 sensoractuator 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.
221
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.

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
222
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
error pattern generator.

Title
Fusion of Palmprint and Iris Recognition in Uncontrolled Environments
Funding
IT
Descript.
The main objective of this project is to design a biometric identification
system to be used in uncontrolled data acquisition scenarios. In order to
do this, and thus enjoy all the advantages of this type of systems
mentioned above, there are four main challenges that have to be solved.
These challenges can be summarized as:
- Acquisition of data with enough discriminating information - This is a
fundamental phase in devising any biometric application. The data
acquisition setup (operating wavelength, type of illuminant, levels of
luminance, number and position of illumination sources) and the protocol
demanded to subjects play a crucial role in the quality of the acquired
data and determine the success of the biometric recognition task. Thus,
a convenient data acquisition framework should be devised in the
earliest stages of the project.
-
Accurate
biometric
data
segmentation
-
As
mentioned
above,
traditional biometric applications, such as computer access and border
control, require the user to submit a biometric in a highly controlled
manner. In this kind of constrained biometric capture, users take
deliberate actions to cooperate with the biometric systems, such as
facing forward and standing still. This makes it easier for the system to
extract the biometric information from the raw image/video data, by
performing a simple segmentation. However, when the acquisition
scenario is relatively uncontrolled, the acquisition system will have to be
able to perform a much more sophisticated segmentation to extract the
desired biometric information from the raw image/video and guarantee
224
that
it
is
not
confused
with
noise,
which
can

high.
- Correction of pose and illumination variations - After being able to
extract the biometric data (i.e., determine its exact location) from the
raw image/video data, the system has to deal with the problem of pose
and illumination variations due to unconstrained biometric capture. After
all, when the capture is done in an uncontrolled fashion, the biometric
data can have different sizes, different orientations, different degrees of
deformation and be subjected to different types of illumination, all of
which have to accounted for in order to be able to perform a successful
user recognition. This process of dealing with the captured data
variability can be seen as form of normalization.
- Robust user identification - After the biometric data has been
normalized, robust recognition algorithms have to be developed for
performing
the
identification
itself.
To
improve
the
identification
performance, more than one biometric trait can be considered, in which

Regularization Criteria and Fast Algorithms for Imaging Inverse Problems
Funding
FCT/PTDC
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
227
project, continuing our successful recent line of work. Bregman iterations
and augmented Lagragian methods will be fundamental tools in our
quest.

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
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
229
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 resonance brain imaging for the
diagnosis of mental illness.

Soft HandOver for Wi-fi networks
Funding
IT
Descript.
This proposal aims at decreasing the disruption of the active sessions
running during the handover by the use of network coding. In our
approach, network coding will be the key enabler towards ensuring soft
handover, providing the correct delivery of all packets in the running
session without duplicating the packets in both networks. In our approach,
the idea is to use network coding to send additional coded packets, i.e.,
linear combination of the original packets, towards the mobile terminal
performing handover, to i) enhance information transmission before the
handover, when the channel quality for both data and feedback is severely
degraded, and 2) improve the probability of correct reception of the
information after the handover, when the exact knowledge of the status of
the terminals is unknown. These two steps shall be instrumental in
achieving a seamless handover. The choice of the number of coded packets
231
to be sent before and after the handover needs to take into account several
issues, such as the mobility pattern of the mobile terminal, signal variation
in both the previous and the new access networks, handover time and the
expected
performance
degradation
while
handover
is
taking
place.
Moreover, the decision of handover with network coding needs also to be
addressed, since it is required to evaluate the cost of handover (in terms of
signaling and performance decrease) and the additional cost of introducing
coding, both in the extra amount of information delivered and its delay in
real-time communications. In this approach, we will target Wi-Fi networks
and the handover of smart phones between different Wi-Fi access points.
The evaluation of our approach will be performed through simulation in the

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
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
232
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

and

services;
• To apply game theory concepts to optimize the cooperation among the
different agents: subscriber terminal access network nodes (gateway to the
operator) and backbone network routers;
• 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.

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 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

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
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.

Applied Electromagnetics – Lx
The recently created Group of Applied Electromagnetics conducts
research activities in the broad domain of the Electromagnetic Field
Theory and its applications to electric, magnetic, and electronic
devices. In 2011 the following interrelated topics have been
addressed:

Transmission-line structures

Skin-effect phenomena

Transformer modeling

Computational methods for electromagnetic field evaluation
4.4.3.3
Group
Transmission-line structures
research
on
transmission-line
structures
is
multifaceted,
encompassing theory and applications, and aiming at a variety of
targets.
The problem of the numerical evaluation of the series-impedance of
uniform multiconductor overhead power lines, taking into account
288
transverse
variations
of
conductivity
and
permeability
of
line
conductors and soil, was analyzed and solved by resorting to a new
developed method that employs elemental current strips instead of
current filaments. The method is general and can be applied to other
transmission-line geometries.
Bundled conductors in triangular and flat configurations are used in HV
overhead power lines in order to mitigate corona and dielectric
breakdown phenomena. Analytical and numerical results, concerning
the comparison between the two bundle configurations were obtained
from the viewpoint of the series-impedance, magnetic field, and
conductor current distributions. Conclusions point out that the flat
configuration is less affected by magnetic field proximity effects.
Magnetic fields produced by underground power cables can endanger
human safety. The important problem of magnetic field mitigation
using shielded cables was solved numerically considering different
options for the shielding material —aluminum shielding proved to be
more efficient.
An investigation path on the novel subject of magnetic transmission
lines was initiated. Signal transmission in magnetic transmission lines
is assured by means of two parallel magnetic-flux carrying magnetic
strips as opposed to the familiar situation of two parallel currentcarrying electric strips. Preliminary research (that led to a patent
submission) suggests that magnetic transmission lines can perform
better than electric transmission lines in the microwave and terahertz
bands.
4.4.3.4
Skin-effect phenomena
Research was focused on inhomogeneous circular cylindrical tubular
conductors, and magnetic cores, exhibiting radial variation of the
medium constitutive parameters.
A matrix approach and a circuital approach were developed for the
evaluation of the pul internal impedance of multilayered conductors,
289
where
each
layer
is
characterized
by
arbitrary
values
of
the
permeability, permittivity, and conductivity.
In addition, it was shown that, when a certain type of radial variation
of the medium parameters is enforced, the skin-effect diffusion
equation transforms into a second-order Euler-Cauchy equidimensional
equation, whose field solution can be described by exact, but simple,
closed-form
expressions
involving
integer
powers
of
the
radial
coordinate —such inhomogeneous media were coined “Euler-Cauchy
media”.
An analysis aimed at the characterization of the complex inductance of
an N-turns coil embracing an inhomogeneous Euler-Cauchy toroidal
core was also developed, taking into account eddy currents in the core
and considering frequencies up to 2 MHz.
4.4.3.5
Transformer modelling
A current transformer of clamp type with a toroidal core was analyzed
from the viewpoint of the eccentricity of the primary circuit where one
conductor goes through the core’s window and the return conductor is
outside the core. Research was focused on the influence of the position
of the primary circuit conductors on the evaluation of the mutual
inductance between primary and secondary circuits. Analytical results
and closed-form expressions for the mutual inductance were obtained
for the case of an air-core transformer. A finite-element method was
also employed for the numerical computation of the mutual inductance
for the cases of air-cores and iron-cores.
4.4.3.6
Computational methods for electromagnetic field
evaluation
The development of computational methods and software tools for
electromagnetic field calculation is key for most of the above reported
research activities of the Group.
290
In what concerns the magnetic field analysis of three-conductor
bundles, a dedicated software package was developed considering the
multipole method for the dielectric medium, and Fourier series and
Bessel functions expansions for the conductors.
In what concerns the magnetic field mitigation problem in shielded
underground cables, a dedicated software package was developed
considering a hybrid FEM/semi-analytical expansion for analyzing the
open boundary magnetic field problem.
In what concerns the magnetic field evaluation in a current transformer
with eccentric primary conductors, a dedicated software package was
developed considering a triangular FEM mesh together with Dirichlet
and Neumann boundary conditions.
4.4.3.7

Summary
This report describes the scientific activities reported under the area of
Basic Sciences and Enabling Technologies, during the year of 2011, at
the Institute of Telecommunications – Aveiro site (IT – Aveiro). During
this year, there was only one group reporting under this topic, the
group of Integrated Circuits. The Integrated Circuits group at the ITAveiro is composed by four effective members, namely: Luis Filipe
Mesquita Nero Moreira Alves, Dinis Gomes Magalhães dos Santos, José
Luis Vieira Cura and Domingos Silva Barbosa. This report is divided
into two sections, namely: section I, presents the group members and
side collaborators and section ii, describes the scientific activities
addressed during 2011.
292
Detailed activities:
The scientific activities addressed by the members of the integrated
Circuits group from IT-Aveiro, during the year of 2011 followed seven
lines: 1) energy efficient concepts for public illumination systems; 2)
energy efficient integrated circuit amplifier design; 3) visible light
communication system design 4) TDOA telemetry for wildlife tracking
systems, 5) SAW based sensors development and design; 6) Radio
astronomy methods for deep space exploration – project GEM; and 7)
Radio astronomy methods for deep space exploration – project
PrepSKA. The activities under these lines have gathered knowledge on
some areas of interest for this group. In some cases, the actions taken
resulted
also
on
the
industrial
contacts
at
both
national
and
international levels. The following description highlights the important
achievements under each of these lines.
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-PSP-2008-2/238916).
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
293
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).
Visible Light Communication System Design – The research under this
topic has started several years ago, with project VIDAS (PTDC/EEATEL/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 evolved modulation techniques, such as
spread spectrum, are required to combat the presence of noise
(especially on outdoor scenarios). This project has reached its
conclusion in March 2011, resulting in several important published
contributions, one PhD thesis and three MsC dissertations. The PhD
student, Navin Kumar received the two prizes for his contributions on
this field: the Gowry award for the best paper published in the IETE
Technical Review and the second place in the Fraunhofer Portugal
Challenge 2011. His work also received honors during the presentation
on the Research day 2011 event held at the University of Aveiro.
Application of visible light communication concepts to other areas
rather than intelligent transportation systems (as in VIDAS project)
has been started during 2011. Possible international co-operations
build up on LITES project has been started aiming for better energy
efficiency
in
public
lighting
systems
supported
on
visible light
communication concepts. These actions are aligned with the agenda of
COST action IC1101 (Optical Wireless: a promising technology),
integrating a member from the Integrated Circuits group.
294
A major shift in research interests occurred in 2010. The main line is
now on surface acoustic wave devices, which will be used both as
identifiers and sensors for various physical magnitudes. Behavior of the
devices will undergo a major improvement by the use of carbon
(diamond-like) thin film deposition. In connection with this line of
work, we have two funding sources: a FCT project, JISIS: PTDC/EEATEL/104004/2008 (which started in 2010) and a new project (QREN
21634) started in October 2011.
Project GEM: In April 2011, we inaugurated with great success and
media coverage the successfully the Cassegrain 9-meter dish from
Vertex/General Dynamics offered by Portugal Telecom. This is the only
current operating radiotelescope in Portugal to be installed and operate
in the radio/microwave sky surveys for space science surveys. A public
demonstration was carried. This constitutes a major achievement
nationally. The international Galactic Emission Mapping project aims to
map and characterize the polarization field of the Milky Way. In
Portugal it will map the sky polarized emission of the Northern
Hemisphere in C-band and provide templates for map calibration and
foreground control of microwave space data to be provided by ESA
Planck Surveyor mission and later missions. The design of the C-band
cross complex correlator was fully tested and published for filed
operation at the antenna as part of its full digital back-end using a lowcost
Field
Programmable
Gate
Array
without
compromising
its
performance relation. This new digital backend comprises a base-band
complex cross-correlator outputting the four Stokes parameters of the
incoming polarized radiation. The publication describes the design and
implementation of the complex correlator using the FPGA and the
dedicated digitizers at each receiver arm, detailing the method applied
at the several algorithm stages. This correlator is suitable for large sky
area polarization continuum surveys.
Project PrepSKA: We developed a full study on the Digital Data Back
Haul for the Square Kilometer Array the same time respond to cost
issues of mass production of important components for the Square
Kilometer Array. This study had a full time engineer, funded at 100%
by IT, as part of our activities and duties in PrepSKA Signal Transport
295
and Networking. The study analyses and classifies the network
topology and technologies of SKA up to 100Gb/sec technology. This
study was presented at a Concept Design Review, in Manchester, June
2011 and approved by an International Panel of experts. Collaboration
with Martifer Solar and EnergyIn - The national Pole on Sustainable
Energy Systems towards the greening of the SKA project. A FP7
proposal with the Spanish and Dutch industry was submitted on this
subject to provide a testbed solution for the SKA prototypes in Moura.
Participation in the ESA Cosmic Vision 2015-2025 proposal for a 4th
generation satellite mission - COrE - aiming a careful measurement of
the tiny polarization of the Cosmic Microwave Background in the band
45-220 GHz, using the GEM project as a clone for foreground and lowfrequency radio noise subtraction. COrE will map the polarization of the
microwave sky with such a high precision, a factor at about 50 better
than what Planck can achieve. COrE will provide maps of the
microwave sky in 15 frequency bands, ranging from 45 GHz to 795
GHz, with an angular resolution ranging from 23 arcmin (45 GHz) and
1.3 arcmin (795 GHz) and sensitivities roughly 10{30 times better
than PLANCK (depending on the frequency channel). The COrE mission
will lead to breakthrough science in a wide range of areas, ranging
from primordial cosmology to galactic and extragalactic science. A
White Paper (90 pages) was published summarizing the science and
spacecraft
design. Following
the May Conferences
on
ICT and
Radioastronomy, we hold at IT a Delta Concept Design Review on the
SKA
Signal Transport and Network (STaN). In partnership with the Optical
Communication
we
were
responsible
for
the
introduction
of
100Gbit/sec technology considerations on the SKA Digital Data Back
Haul design and its impact on sensor networking having released the
results on a international SKA report (co-supervision of an engineer).
This was presented in June 2011 at the SKA STaN Concept Design
Review held in Manchester for an International Evaluation Panel of
experts selected by the SKA project and Funding Agencies within the
project. The results were publicly displayed in December 2011
(Netherlands) having solved the IO subsystem and networking of
296
dense sensor Aperture Array systems (AAVP 2011 Conferences,
Dwingelloo). A summary of this work was awarded the Best Poster at
the Research day of University of Aveiro. Organization of the
conference “The Growing Demands on Connectivity and Information
Processing in Radio Astronomy from VLBI to the SKA” joining the
Square Kilometer Array (SKA) and Nexpres projects. This conference
was
organized
by
the
joint
collaboration
of
the
Instituto
de
Telecomunicações – Aveiro, Universidade de Aveiro and TICE. This
event focused on research convergence aspects common to both Space
Science and Technology and ICT domains.
4.4.3.10
The Integrated Circuits Group (ICG), IT-Lisbon, research activity in
2011 lead to the following achievements:
 Design of an integrated overcurrent detection system for bridge-tied
load class-D audio amplifiers. A proof-of-concept implementation was
designed on a 3 V, 0.18 μm CMOS technology, within a BTL output
stage rated for maximum output power of 1 W. The proposed solution
provides current savings of up to 38%, with a small increase in the
detection time for BD modulation compared with a conventional
configuration.
 Design of radiation hardened DC/DC converters controlled with PWM
current mode control or PFM methods to be employed in the aerospace
industry, 0.35 μm CMOS technology. In order to solve stability issues,
the PWM switch model was applied to a multi-output forward
converter.
 Development of a low power Digital-to-Analog converter for audio
applications. The chosen oversampled Delta-Sigma converter was
design in a 0.18 μm CMOS technology. The signal is upsampled with a
multi stage of FIR and CIC filters to 128 times the Nyquist frequency. A
third order, 4 bits Noise-shaper is used. This choice can deliver high
resolution, above SNR=103dB, i.e., more than 16 effective bits.
297
 Development
of
an
innovative
solution
for
analog
IC
design
automation, particularly, for circuit-level optimal sizing. The proposed
system, FUGA, implements a new design automation strategy based on
a single-objective genetic algorithm kernel combined with fuzzy logic
system. The fuzzy logic system introduces design knowledge into the
GA kernel providing an effective guidance, increasing the quality of the
results and reducing the required number of generations to reach the
desired solution.
 Development of an innovative solution for analog circuit-level sizing,
GENOM-MO, based multi-objective optimization and Pareto optimal
fronts extraction. The approach uses a modified NSGA-II algorithm in
order to tackle the design problem together with NGSPICE as the
evaluation engine.
 Development
of
an
analog
IC
sizing
and
layout
generation
methodology, AIDA, in cooperation with CTS-UNINOVA and RMOM-IT.
The approach uses modified NSGA-II kernels for both sizing and layout
tasks using HSPICE and CALIBRE as evaluation engines.
A proof-of-
concept is being prepared for a state-of-the-art IC in a 0.13 μm CMOS
technology.
 Development of a system-level sizing and behavior simulation tool for
pipeline analog-to-digital converters, in cooperation with ThalesAlenia
Space.
4.4.3.11
Organic Electronics - Lx
In 2011, the scientific activities in Organic Electronics, foccused on the
fabrication and test of organic electronic devices, including molecular
wires, plastic optical fibers, organic light emitting diodes (OLEDs),
organic memories, plastic photovoltaic solar cells, organic field effect
transistors, and the study of physical properties of materials for
organic electronics.
The detailed activities included:
298
Molecular Electronics (Molecular Wires)
i) Studies on the self-assembly process of porphyrins on highly
oriented pyrolitic graphite (HOPG), in particular, the first steps that
anticipate the formation of fully packed monolayers.
ii) Use of Conductive AFM-break junctions as a new alternative to the
methods previously used to characterize the electrical properties of the
molecular wires grown stepwise on HOPG.
iii)
Characterization
of
monolayers
on
graphite
using
scanning
tunneling microscopy (STM)
iv) Study of electrical tansport of conductive molecular wires using STM
and conductive atomic force microscopy
v) Theoretical calculations by quantum mechanics of the shape of
Molecular wires.
Plastic Optical Fibers
Preparation of new fluorescent molecules to be used as dopants in
plastic optical fibers and films. The photophysical properties of some of
the compounds were studied at the Istituto Politecnico di Milano. This
work is a follow-up of the activities developed within the EU-funded
project (POLYCOM), via Instituto Superior Técnico, which ended in
2009.
Organic Light Emitting Diodes (OLEDS)
i) Polymer based Light-emitting diodes (OLEDs), in particular, a study
on new boron-based complexes to be used as luminescent layers.
ii) OLEDs were also fabricated using a set of polymers obtained via a
collaboration with ISEL-Lisboa. The study of the influence of bipolar
charge traps and thin oxide interlayers on LEDs performance was also
continued.
Organic Memories
The activity on resistive nonvolatile organic memories was mainly
focused on diodes based on blends of a ferroelectric polymer with a
conjugated polymer. The major task has been the investigation of the
appropriate conditions to form compact films from such blends
solutions by spin coating. AFM was used to characterize such films.
299
Polymer Based Photovoltaic Cells (OPVs)
i) A significant effort was devoted to the synthesis of new materials
and
fabrication
of
polymer-based
photovoltaic
cells
(OPVs).
In
particular, a new family of cross-linkable conjugated polymers, derived
from polyhexylthiophene, was prepared. Studies were made on
surface patterning of thin films, to be used in OPVs by combination
with PCBM, an approach that has been previously developd for a
different polymer family. OPVs were fabricated and characterized.
ii) Fabrication and characterisation of organic Photovoltaic cells with
(organic)
active
layer
comprising
different
device
arquitectures:
nanostructured polymer films, blends and planar bilayers of crosslinked polymers with an electron acceptor component. These studies
allowed to establish comparisons between the performance of organic
active layers with nanostructured interfaces and with «conventional»
architectures, such as blends or bilayers.
iii) Synthesis of the copolymer with a low-bandgap conjugated
polyfluorene, and with an extended absorption range, overlapping well
with the solar spectrum.
Biocellulose for Printed Organic Electronics
i) Fabrication and characterization of organic thin film transistors using
biocelullose and chitosane-based materials either as substrates or
dielectrics.
ii) Optimization of the conditions for inkjet printing of electronic
materials,
including
poly(styrenesulfonate)
silver,
(PEDOT),
poly(3,4-ethylenedioxythiophene)
poly(4-vinylphenol)
(PVP)
and
poly(9,9-diocthylfluorene-bitiophene) (F8T2).
iii) Development of organic field effect transistors (OFETs) fabricated
by inkjet printing using bacterial cellulose (BC) as substrate. Silver and
PEDOT were used as contacts; a mixture of BC and chitosan or PVP
were
used
as
dielectric;
F8T2
or
pentace
were
used

Fault diagnosis of aluminum electrolytic capacitors
The development of simple, precise and cheap fault diagnostic
techniques that can evaluate the capacitor condition is essential to
avoid unexpected breakdowns in different
electronic equipment.
Aluminum electrolytic capacitors are one of the most common
capacitors in electronics due to their excellent characteristics, like very
302
high volumetric efficiency, small price and a very wide range of voltage
and capacitance ratings. Unfortunately, due to their high losses, the
lifespan is short. These capacitors are considered one of the most
vulnerable
elements
of
switch
mode
power
supplies
(SMPS),
uninterruptible power supplies (UPS) and adjustable speed drives
(ASD).
The Study of Aluminum electrolytic capacitors aging process
The development of precise fault diagnosis for aluminum electrolytic
capacitors requires the knowledge of capacitors aging process. This
study is essential to predict the capacitors aging mechanism during its
operation. In many applications, the stoppage of the equipment is not
always possible, so the prediction of faults is essential to avoid
unexpected breakdowns.
Behavior of a Three-Phase Induction Motor Fed by a Fault
Tolerant Multilevel Inverter
Nowadays energy efficiency is an issue of vital importance for the
society and for industry in particular. That is why the losses of an
induction machine should be reduced, either in normal or faulty
operating mode. For this purpose a 2D finite element model to study
the induction machine behavior under normal and faulty conditions was
developed. Machine faults like airgap eccentricity, stator winding shortcircuit, broken rotor bars were considered. These models allow also to
study the thermal behavior of the machine under these faulty
conditions.
Fault Tolerant Cascade Multilevel Inverter for Electric Vehicle
Applications
A state of the art about fault diagnosis methods that can be used in a
Cascade Multilevel Inverter was obtained. The mathematical model
developed for the power converter allows to compensate an opencircuit failure in a power semiconductor. Based on the reconfiguration
of the control strategy, the converter will feed electrical machine with a
303
balanced line voltage. Simulation and experimental results were
obtained.
Transformerless topologies for railway train power supply
The purpose of this work was to analyze the operation of a singlephase multilevel rectifier, based on cascaded H-bridges in order to
replace the power transformer in electric railway traction applications.
In a first stage, an overview on existing transformerless topologies for
electric railway traction applications and their main features was
investigated.
Then a drive description and a mathematical model for simulation
purposes were developed for a multilevel topology based on cascaded
H-bridges. Several simulation and experimental tests were performed
and the results were compared with a conventional diode rectifier for
operations under normal and faulty conditions.
Performance of three-phase induction motor with asymmetrical
supply
The aim of this work was to investigate the performance of a threephase induction motor fed by an asymmetrical sinusoidal supply
voltage. For this purpose, a three-phase power source was developed,
having the direct and inverse voltage components, both simultaneously
controlled. This voltage source allows to feed the machine with
different levels of unbalance voltages and, therefore, the derating of a
three-phase induction motor could be analyzed. All machine derating
tests were accomplished for the same nominal motor temperature
variation. Several experimental tests were conducted in agreement
with NEMA rules.
Fault Diagnosis in High Power drives based on Multilevel
Converters
The
developed
work
comprised
an
investigation
on
modulation
techniques, suitable to be used on a NPC multilevel inverter. The
SVPWM modulation technique was adopted to be used in this work.
Several simulation and experimental tests were accomplished in order
304
to select the most appropriated switching frequency under normal
operating conditions. Given that this multilevel inverter has more
power semiconductors than the traditional two level inverter, methods
of
fault
diagnostic
and
fault
tolerant
control
strategies
were
investigated in order to be implemented in the converter and thus
increase their reliability. Several diagnostic methods based on voltage
and current measurements were analyzed, especially those based in
the Park’s Vector theory. Experimental and simulation tests were
conducted in order to evaluate their efficiency.
Electronic ballasts for fluorescent lamps
A research and development on new control techniques for electronic
ballasts based on magnetic regulators were accomplished. 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.
Diagnosis of faults in induction motors
Eccentricity faults in induction motors are very common. Typically they
can result from manufacturing defects such as rotor unbalance and
from assembling conditions where the machine shaft is subjected to
uneven mechanical efforts. Hence, it is intended to develop on-line
fault diagnostic methods that can effectively detect different types of
these faults, namely static and dynamic eccentricity, and evaluate the
severity level of each one.
Although rotor broken bars do not initially cause an induction motor to
fail, there can be serious secondary effects. The fault mechanism can
result in high current levels and broken parts of the bar hitting the end
winding or stator core of a high voltage motor at a high velocity. This
305
can cause serious mechanical damage to the insulation and a
consequential winding failure may follow, resulting in a costly repair
and lost production. Considering this, in this topic is intended to
develop diagnostic techniques for the detection of rotor broken bars in
induction motors, which also allow to evaluate its severity level.
Approximately 30% of all motor faults are caused by failure of motor
winding due to insulation problems. The majority of induction motor
winding failures is gradually from lower short-circuits current to higher
level and finally broken. Taking this into account, this topic is focused
on the development of diagnostic techniques that allow to distinguish
short-circuit faults in the windings of three phase induction motors.
Different numbers of short-circuits turns are considered in order to
simulate distinct severity levels and to correct evaluate them.
Diagnosis of rotor and core faults in motors coupled to timevarying loads
Induction motors are nowadays used in a wide range of industrial
applications. Many of these machines are coupled to time-varying
loads which increases the difficulty of faults detection. For this reason,
it is important the development of diagnostic methods for these
specific working conditions that can lead to an improvement of the
reliability of these applications. Therefore, the main objective of this
research is the development of diagnostic methods able to diagnose
induction motor faults specially the ones related with the rotor bars
and magnetic circuit. Taking into account that induction machines are
very often supplied by power electronic converters, new fault diagnosis
methods have been investigate in order to detect and locate faults an
machines operating in closed-loop.
Modelling, analysis and fault diagnosis in three-phase power

Power

occurrence of a fault in a transformer can thus result in significant

306
Consequently, there is a huge demand for the development of
diagnostic techniques that can be applied for the on-line diagnosis of
faults in the most critical elements of a transformer, including the
windings and core. In this context, a new diagnostic method has been
developed for the detection of faults in such transformer components.
A simulation model was implemented to study such faults, both in
core-type and shell-type transformers, and experimental tests were
also performed with the same aim. On-site tests were successfully
conducted at a power generation plant in transformers rated 60 MVA,
10 kV/ 240 kV, hence demonstrating the usefulness and applicability of
the diagnostic tool developed.
Validation
of
the
models
of
the
components
previously
developed (PV, Wind, battery and DC/DC DC/AC converters)
In the previous years of the research programme, models were
developed to simulate the behavior of PV, Wind, battery and
converters. The models have been designed to be as general as
possible taking both design parameters and specific component
characteristics obtained from manufacturers or from experiments into
account. Each model is a self-contained module which can stand on its
own, and is fully documented with respect to usage, governing
equations and reference material. A validation of each of the
implemented mathematical models was performed by an interactive
analysis and comparison between simulation results and data from
literature.
 Simulation of Photovoltaic Cells on a Generic Surface Geometry: The
model of the Photovoltaic Generator has been improved by adding an
innovative feature in order to simulate generic surface geometries.
This new feature allows to investigate and simulate the behavior of a
Photovoltaic Generator to be installed on a generic surface considering
any kind of surfaces, also curved and moving ones. The realized model
has been validated comparing various commercial solar panels. The
developed model is very versatile and can be used to analyze the
possibility to exploit various available surfaces in order to produce
photovoltaic energy in many different applications.
307
 Measurement campaign on hybrid PV-Wind plant: Thanks to the
availability of a real PV-Wind plant for telecom applications provided by
an Italian company it has been possible to validate the developed
models through a measurements campaign and experimental tests.
Based on the developed models the PV-Wind plant has been first
simulated in different operating conditions and results obtained from
simulations were then compared with actual data measured on field.
The possibility of having a real system and real experimental data has
made it possible to refine the developed models and to transform them
into a real operational design tool.
 Identification of condition monitoring, diagnostic techniques and
advanced control techniques and methods to identify failures or
potential failures in the components of a Wind System: A deep study of
the various control strategies has continued to model and describe the
interactions between components and to manage the energy flows.
The specific study and analysis of condition monitoring and diagnostic
techniques for a WIND SAPS also started to develop advanced control
techniques to identify failures or potential failures in the wind
generator. The obtained results will be used to identify a suitable
interface
taking
into
account
reliability,
availability,
condition
monitoring and remote diagnostics together with fault tolerance.
 Energy storage devices: Experimental results from the test plant have
been used also to deeply investigate the behavior of energy storage
devices. The model of the battery developed in the first year has been
improved with a new analytical model. This new feature of the model
uses a data driven procedure based on a genetic algorithm to derive a
few
quantities
of
interest
which
are

the
corresponding measured ones.
 Other research topics: As a result of the scientific interests of the
researcher, a parallel research activity has been carried out to design
and implement a novel instrumentation system for the detection of
small biological currents. A current acquisition system, a non invasive
probe and a software tool have been realized. Even if these research
topics are not related with the objectives of the FCT research grant,
they represent an interesting and challenging subject that give an
308
important and meaningful contribution to the student’s scientific
background.
Energy management of hybrid multigeneration plant powering
TLC systems
Tri-Generation represents a competitive choice with respect to the
adoption of conventional methods for supplying power and cooling to
loads demanding different energy carriers. The configuration objects of
investigation takes advantage of the availability of natural sources
such as sun and wind through the insertion in the prime mover group
of a wind generator and Photovoltaic and thermal panels to generate
electricity and hot water. The integration of renewable energy sources
to fossil fuelled prime movers in a HTS increases the complexity of the
overall management of the system. In this light, the research has been
focused on the development of a power management strategy based
on the implementation of neural network techniques for a trigeneration
system aimed at feeding a TLC load. The conclusions of the study
confirms the necessity to devise efficient control strategies in order not
to incur in operational mismanagement of the trigeneration plant that
would
result
in
economic
losses
related
to
excessive
gasoline
consumption and service life reduction.
 Optimization techniques applied on hybrid multigeneration plants
powering TLC systems Multigeneration power systems placed in area
not connected to fuel networks provide a strong incentive to the
adoption of optimization techniques aimed at maximising the economic
benefits of this kind of plants. Tri-generation systems can provide high
payoffs in terms of carbon emission and energy cost reductions but
require significant investments. A variety of variables in the expression
of capital and operative costs has been considered and an optimization
problem formulated and solved based on hierarchical optimization
algorithms. Simulations have been carried out with dedicated software
to verify the effectiveness of the proposed method. Trough this
investigation the influence of the main parameters affecting the
economic planning of a trigeneration system has been deduced.
309
Recommendations and further conclusions are expected when more
realistic data will be available.
 Multiscenario Economic Analysis of trigeneration plants: The aim of
the study has been to develop an investigation into the main variables
influencing the performances and thus the cost of the electricity
(kWhe) generated in the case a trigeneration plant is powered by a
Concentrated Photovoltaic and Thermal (CPVT) equipment or by an
Internal Combustion Engine (ICE). The analysis has been carried out
by considering the influence of the level of solar radiation, the solar
concentrator initial capital cost and the quality of the technology
characterizing the separate production. External parameters such as
the price unit of subsidies granted for polluting emission reduction and
fuel saving achievement are thus considered and varied according to
discrete values. The results provide good prospects about the potential
use of solar concentrators in cogeneration applications in medium or
high solar radiation area. It has been demonstrated that the cost of the
kWhe can attain zero values in several combinations of appropriate
financial aids and within the subsidy prices contemplated for both the
CPVT and the ICE.

Instrumentation and Measurement
Scope and Objectives:
The Instrumentation and Measurement Group works in the broad
domain of Metrology. In 2011 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
310
A detailed report of the activity in each topic follows.
Analogue-to-digital and digital-to-analogue conversion
 Continuation of the study of the uncertainty of analogue to digital
converter test methods, namely of the Histogram Test Method, the
Random Noise Test Method and the Sine Fitting Test Method.
Consideration of different non-ideal effects like additive noise, jitter,
phase noise and harmonic distortion.
Measurement of electrical quantities
 Implementation of a PC based three-phase power quality analyser
using multi-harmonic sine-fitting, morphological operations for event
detection and classification.
Non-destructive testing
 The research work during 2011 was related with two I.T. internal
projects: CLASSE and OMeGA. CLASSE ended in 2011 and aimed at
classifying defects inside conductive non-magnetic plates using the
eddy current method. OMeGA started in 2011 with the objective of
detecting defects inside metallic parts, but using ultrasonic methods
optically excited.
Work on the area of non-destructive testing using eddy currents went
on and the application was extended to determine thicknesses. Two
types of excitation currents have been used: Pulsed Eddy currents
(PEC) and sinusoidal currents.
The use of algorithms in the area of digital signal processing to process
and interpret data provided by the sensors used in the laboratory for
eddy current testing proved to be very effective to overcome the poor
performance of some of these sensors. Significant improvements in the
crack position accuracy 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 and inversion algorithms based on the de-
311
convolution in the discrete Fourier transform domain with Tikhonov
regularization.
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 magneto-resistor 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.
A new non-destructive testing method is being tested. The conductive
material being tested moves in a time constant magnetic field and due
to the movement the induced currents in the conductor generate a
secondary magnetic field. When the current flow pattern is disturbed
by the existence of defects, variations of the magnetic field occur and
information about the defects can be assessed by measuring the
magnetic field. As far as the authors know this is an original method,
that has not yet it been reported in the literature, and presents
undoubted advantages when the material to be tested is in motion
relative to the test sensor (like when inspecting a rail track with a
bogie).

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.

Title
Flaw Imaging in Metals by Contactless Conductivity
Funding
FCT/PTDC
Descript.
The measuring principle is based on the phenomenon whereby the
319
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
320
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

Just in Time Dendrimers
Funding
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€œpH-drivenâ€• efficient
drug nanocarriers and (ii) new chemical sensors. The dendrimers
preparation will be performed using an 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 layer-bylayer (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
321
unexplored potential opens-up for exciting opportunities that we will
systematically explore: i) using the dendrimers library without endcapping for explosives detection ii) using perylene end-capped
dendrimers for detection of metal cations.

Global environmental concerns and the ever-increasing need for
energy, coupled with a steady progress in renewable energy
technologies are opening up new opportunities for utilization of
alternative
energy
resources
for
telecommunications
(TLC)
applications. The equipments used in TLC have strict specific
requirements in terms of type and quality of the power supply and
most TLC energy systems present a special energy supply challenge,
requiring reliable, unattended power system operation in locations
where grid power is not available. For these applications, interest in
stand-alone power systems (SAPS) is increasing and the value of
alternative power solutions is becoming more apparent. Considering
this, the main general objectives of this research program are:
• The investigation of the new available technologies for the
generation
and
storage
of
energy
for
TLC
applications;
• The development of a SAPS capable of self-diagnosing power
converter faults and, in case of a failure occurrence, to keep its
normal operation, although with a reduced performance.

Kernel Method Applied to Non Destructive Evaluation
Funding
IT
Descript.
Throughout the world, engineers and technicians are working
together finding cracks and other anomalies to prevent expensive
failures. The increasingly important role of nondestructive testing in
public security and safely technology development promote new and
innovative methods to be developed and already known methods do
be enhanced. Eddy Current Testing (ECT) is one of the most
324
established nondestructive structure evaluation technique that
enables defect detection and material condition monitoring with high
sensitivity and reliability. Within this method the volume distribution
of the material conductivity is determined by inducing eddy currents
inside the conductor under test and measuring the magnetic field
produced by those currents [6]. ECT is used with electrically
conductive materials for the measurement of the thickness of
metallic plates [7] or non-metallic coatings or metal substrates,
estimation
of electrical
conductivity or magnetic permeability
distribution, corrosion detection [8] and the determination of
surface or subsurface defects [9]. However, regarding safety and
economic efficiency assessment, defects are still the main concern
and
with
the
improvements
on
understanding
the
facture
mechanics, the detailed geometric characterization of the cracks,
still an open problem, became the target of the research in the
area. One disadvantage of this type of method is related to the
inevitability of well qualified and experienced technicians to perform
the tests since, in spite of its implementation simplicity, data
produced by eddy current based equipment are among the most
complicated to interpret. These factors together motivate the
project objectives: to implement new and better measurements
with both novel instrumentation and embedded artificial intelligence
to automate the interpretation of the various imaging data streams
in order to determine surface and subsurface defects shape and size
[10].
With eddy currents nondestructive evaluation, the dimensions of
defects are retrieved by inversion of the measured signals. Since
the physical model of the problem is often complicated and nonlinear, the inversion model is ill-posed and it’s solution always a
challenge. Within this project an original strategy based on the
current lines distribution is proposed. The idea is to assess the
current density perturbation caused by the defects through a bidimensional map of the magnetic field components on the surface of
the material to be tested, obtained experimentally. This current
density can be represented as a composition of magnetic dipoles.
325
The field of the single magnetic field dipole will be the kernel of the
transformation to be used in the inversion process. Measurements
are
taken
using
electromagnetic
sensors
based
on
giant
magnetoresistive (GMR) effect. GMRs extend the application field of
eddy current non destructive evaluation methods since they
measure the magnetic field directly and their sensitivity is equal for
all
working
frequencies,
allowing
better
performance
than
conventional probes for low-frequency applications as, for instance,
when detecting defects deep buried in multilayered structures.
Besides, these sensors are far more sensitive than those used in
current commercial equipment [11] and the output signal signal-tonoise ratio is high enough to apply regularization methods to extract
information.
It is our goal to develop a competitive automated system to be
subsequently exploited and used in the industry. This project
besides its technical and scientific objectives is also focused on
promoting nondestructive evaluation issues to young researchers. It
is a multidisciplinary field of study that embraces issues like: (1)
technology development; (2) image processing and recognition; (3)
modeling
and
algorithms.
In
Portugal
there
are
very
few
competencies within the nondestructive testing knowledge area in
spite of the abundance of industrial relevance for them and as a
result Portugal is losing competitiveness in a 600 million global
market.

The main objective of this project is to develop an electric drive,
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

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

NANOPEPS
Micro- and Nanopatterning of cross-linkable electro-active 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
328
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 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
329
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.

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 gradedindex waveguide, and (v) circumvent oxygen interference. The
expected results for the â€œSolarNHyMatâ€• project taking into

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

The coupling of ultrasound waves into solid media on a material
surface point followed by the wave detection on another point can
be used to infer about the wave propagation conditions. The wave
suffers reflections on the material boundaries, but is attenuated or
diffracted on existing material discontinuities. It is possible to obtain
valuable information about material defects by an accurate analysis
of the wave propagation conditions. In this project we intend to
apply the ultrasound method to establish an experimental method
of defects detection inside solid structures whose structural health
monitoring is of great importance. This is the case of the aircraft
structures, the liquid or gas pipelines in nuclear power plants or
other containers subject to high pressures. To our knowledge, the
most important inspection task at this time is the assessment of
possible internal defects inside the stainless steel containers of the
International Thermonuclear Experimental Reactor (ITER).

The baseline design for the SKA is an interferometer array capable
of imaging the radio sky at frequencies from ~70 MHz to ~25 GHz,
and providing an all-sky monitoring capability at frequencies below
1 GHz. The telescope is to be built in three phases, and will be able
to carry out significant scientific observations as it is being built.
The concept involves parabolic dishes with innovative feeds to
maximize a combination of spatial and frequency coverage; at lower
frequencies phased arrays can become cost-effective and offer new
operational capabilities. Technological innovation, closely paralleling
commercial IT developments, is the key to the design concepts
under investigation and to the target cost of 1.5 billion Euro. Data
transport rates are likely to be in the range of 100 Giga-bits/sec to
Tera-bits/sec, with Petaflop capacity required for the central
processor. Much of the required technology is currently being
developed in the course of specific design studies (including the EC
funded FP6 SKA Design Study, SKADS) and the construction of
several SKA Pathfinder instruments around the world. The final step
of integrating the accumulated R&D knowledge into a detailed
system design for the SKA, is planned to take place from 2008 to
2011, with the first three years being under the aegis of PrepSKA.

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
334
(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.
