Introduction
1.1
History
Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an association of nine
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 Solutions and Networks S.A
• Universidade da Beira Interior (UBI)
• Universidade do Porto (UP)
• ISCTE – Instituto Universitário de Lisboa (ISCTE-IUL)
• Instituto Politécnico de Leiria (IPL)
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 branches:
• 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.
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since 1993, it activities
proceed regularly.
6
it bylaws were first approved in 1992, modified in 1997, 2003, 2011, 2014 and 2015. New Site
regulations deriving from it bylaws were approved and implemented in 2011.
Key developments in 2015 are highlighted ahead. Details are included in the sections dealing with each
of the research areas.
1.2
Management
it is managed by a Board of Directors, elected by the General Assembly, and by Site Management
Boards, which include the site members of the Board of Directors. Site Management Boards enjoy ample
freedom to deal with current affairs and usually meet weekly. The Board of Directors meets at least
once a month.
it scientific activities are overseen by the Scientific Board, which includes all it researchers holding a
Ph.D. degree. The Scientific Board meets in Plenary or in Committees, both permanent and temporary.
There are two permanent committees: the Science and Technology Committee and the Research Group
Coordination Committee.
it Work Plan and the Annual Report are discussed with the Advisory Committee, formed by three
independent experts in the field of telecommunications (Prof. Sir John O’Reilly, Prof. Touradj Ebrahim
and Prof. Thomas Brazil) acting in a personal capacity, and together with the Accounts Report (after
legal certification) are subsequently submitted to the General Assembly for approval.1
The General Assembly met formally twice in 2015. The first meeting was held on March 25th, at ISCTEIUL premises, Building II, to discuss and approve the 2014 Annual Report and Accounts and to discuss
and approve an amendment to it statutes. The second meeting took place on December 22th, again in
the Meeting Room of the Aveiro site, to discuss and approve the Work Plan and Budget for 2016 and to
discuss and to approve a further amendment to it Bylaws required by law.
The Research Group Coordination Committee also met twice during 2015. On the first meeting, held on
March 18th, at ISCTE-IUL premises, Building II, Room B103, Lisboa, the Draft Proposal of the 2014
Annual Report was discussed and received a favourable opinion and the intermediate reports of the first
batch of internal projects were presented and discussed.

it would like to pay tribute to Prof. Martin Tomlinson, for all the help, support and friendship since 1998
7
On the second meeting, held on December 16th, Meeting Room of the Aveiro site, the Work Plan and
Budget for 2016 was discussed and received a favourable opinion.
The proposal for an Engagement Index was thoroughly discussed and rejected while its main ideas
should be included in a Code of Practice to be discussed in the next meeting.
1.3
Highlights of 2015
In 2015, in spite of serious reduction of funding, mainly from FCT strategic funding, the momentum built
in previous years enabled achieving a significant scientific output:
• 11 books;
• 61 book chapters;
• 387 papers in international refereed scientific journals;
• 545 papers in refereed conferences, with published proceedings;
• 9 patents
where the forecast was:
• 15 books;
• 50 book chapters;
• 250 papers in international refereed scientific journals;
• 450 papers in refereed conferences, with published proceedings;
• 8 patents
Achieved scientific output exceeded by far our forecast, namely in the number of papers in international
refereed scientific journals. The small reduction in the number of books may be attributed to the
reduction in funding.
Fostering advanced education was also maintained at very high levels:
• 34 PhD theses, submitted and approved,
• 262 MSc theses, submitted and approved,
where the estimated numbers for 2015 were:
• 35 PhD theses, submitted and approved,
• 200 MSc theses, submitted and approved.
8
The number of PhD theses submitted and approved decreased significantly from the previous year when
it reached an all time high (62). The number of MSc theses submitted and approved exceeded
significantly our forecast. This may be due to the fact that during 2015 we checked far more thoroughly
the number of MSc theses and the current value should be much closer to the real value than in
previous years.
The number of scholarships decreased significantly in 2015 with respect to 2014, not only due to the
reduction FCT strategic funding (as explained in more detail below), but also and mainly because of the
decrease in the number of scholarships funded by FCT:
• 224 Ph.D. scholarships, funded by FCT,
• 143 other scholarships, funded by it as follows:
• 24 post-doc scholarships;
• 26 scholarships for BSc graduates;
• 84 scholarships for MSc graduates;
• 8 R&D starting grants;
• 1 S&T management;
During 2015, 155 projects, of which 126 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 running 18 FP7 projects and 14 projects funded by industry (2 of which international). It
should be noted that not all projects mentioned in section 2 are funded through it.
In the past few years, FCT strategic funding, ie. funding for the IT - Laboratório Associado contract, in
addition to a sharp decrease was never timely. Strategic funding for the period 2011- 2012 was 3.0
M€/year, for the period 2013-2014 to 1.6 M€/year (100 % execution rate) and for the 2015 to 1.2 M€.
In spite of the fact that the first payments for the period 2013-14 came in with a 9 month delay (August
30th, and October 31st 2013) FCT imposed the 31st of December 2014 as the closing date for the
contract. Later this date was postponed (albeit with a penalty) to the 31st of March 2015. In effect the
9
penalty meant a delay in the execution of the 2015 funding, that run from April 1st, 2015 to March 31st,
2016.
With the delay and the new procedures introduced by our General Director, it managed to execute 100
% of the 2014 funding.
Due to the fact the 2015 strategic funding may be used up to March 31st, 2016, the execution rate for
the 2015 strategic funding is not yet available.
As mentioned in the Annual Report for 2013, during 2013 FCT decided to organize an evaluation of all
Portuguese R&D units making it possible for these units to adopt configurations other than the current
one. Although the funding rules favored smaller units, it, faithful to its principles, decided to keep the
same structure. The proposal was submitted on the 30th of December 2013.
The proposal evaluation ran in two phases. For the first phase the proposals were evaluated in four
criteria (with grades from 1 to 5 in each item):
A. Scientific productivity and contribution to the National Scientific and Technological System;
B. Scientific and technological merit of the research team;
C. Scientific and innovative merit of the strategic program;
D. Feasibility of the work plan and reasonability of the requested budget.
The results of the first phase were made public on the end of June 2014. Most surprisingly it got very
low marks (15/25), distributed as follows: A=4, B=4, C=3 and D=4. Even if the total (15/20) would allow
access to the second phase, the 3 in item C would forbid it.
In addition to many factual errors and mocking phrases that should never be used in an evaluation
report (according to FCT published guidelines), the evaluation report showed hints of manipulation to
achieve a pre-defined result. It suffices to say that C=3 was not the average grade of the (supposed) 3
evaluators. The average grade of 3 was in item D a situation that would not bar it from the second
phase.
10
In the first phase rebuttal it appeal was successful and the overall marks was amended to 16/20,
A=B=C=D=4.
The visit, the major item of the second phase of the evaluation, had strict rules (imposed by FCT) that
did not take into account neither the number of sites nor the number of researchers or students
involved in the research unit. The visit had to be restricted to one site and 3 hour duration (1 hour with
the directors, 1 hour lab visit and1 hour meeting with researchers and students.
For the second phase a further item of evaluation was added:
E. Impact of the scientific, technological and cultural output.
it decided to stage the visit in the Aveiro site and to prepare a rather imposing poster and demo session
(with 107 posters, 20 demos and about 200 researchers and students). It was pretty obvious after the
visit that three evaluators were well impressed. And surely the evaluation report bear it out. The overall
grade was 22/25 (VERY GOOD), with A=4, B=4, C=5, D=4, E=5.
So, for the second time, it strategy was re-evaluated, now to the maximum (further confirming our
initial suspicions).
According to the law it appealed again, on the 19th of January 2015, this time after having had access to
the evaluation forms of the other research units in the area, in particular the only one that had been
graded higher than it. The appeal resulted in an increased from 22/25 to 22.5/25 (VERY GOOD), 0.5
points short of the Excellent label it we believe is due.
On June 8th, 2015, it appealed yet again, now on the basis of unfair comparison with research units in
the same scientific area, with higher marks. On February 26th, 2016, as the result of the last appeal it
was finally graded EXCELLENT (23/25). As a consequence it funding would get a significant boost.
On September 17th and 18th it organized the 10th edition of its international conference Conftele 2015.
This time the conference was embedded in a technology fair, TECHDAYS, organized together with the
Universidade de Aveiro, INOVARIA, TICE.pt and the Aveiro Municipality held at Aveiro EXPO. The
conference had 157 participants. The technology fair included 54 exhibitors in addition to it own
11
prototypes and demonstrations. The number of participants (1127) is a tribute to the growing public
interest in it research and development products.
The Advisory Committee visited the Aveiro site, on the 16th of September and Conftele 2015 and
TECHDAYS, on the following 2 days. During this visit the Advisory Committee had the opportunity to
examine in detail some of the latest it research work and held most fruitful discussion with the
Management Committee and with many researchers. The Advisory Committee report has already been
sent to the associates and to FCT.
During 2015 one it researcher, Prof. Mário Silveirinha was elevated to the grade of Fellow of the IEEE
(Institute of Electric and Electronic Engineers) and three it researchers, namely Prof. Dr. Fernando
Pereira, Dr. Jonatan Rodriguez and Prof. Dr. Rafael Caldeirinha were elected to the grade of Fellows of
the IET (Institution of Engineering and Technology). Also in 2015, two it researchers, Prof. Dr. José
Bioucas Dias and Prof. Dr. Mário Figueiredo were named Thomson Reuters Highly Cited Researchers
2015, the latter for the second time in a row. It is also worth while mentioning the “Outside Team
Award”, from Hauwei Technologies Sweden, for outstanding collaboration in the design of microwave
frequency power amplifiers.
In addition to the above during 2015 it researchers were awarded the following prizes:
-
1 “ANACOM-URSI Portugal 2015 Award”;
-
1 EuMC Microwave Prize;
-
1 Award Abreu Faro, for the best PhD Thesis submitted to IST;
-
1 Best Iberian Thesis on Information Systems and Technologies;
-
2 Young Engineers Innovation Award (1st and 2nd place);
-
1 “Novas Fronteiras da Engenharia” prize from “Ordem dos Engenheiros”;
-
4 Fraunhoffer Challenge 2015, 1st and 3rd place PhD, 2nd and 3rd place MSc;
-
1 iUP25k 2015 prize, 1st place;
-

12
During 2015 it hosted the following national and international events (details in each scientific area):
-
18 Seminars;
-
5 Talks;
-
1 Colloquium;
-
2 Workshops;
-
2 One-week short courses for secondary school (20 pupils each);
-
2 Winter/Summer Schools;
-
1 Technology Fair (TECHDAYS);
-
4 major International Conferences.
it is a member of the CIENCIA VIVA, the National Agency for Scientific and Technological culture and cooperates in some of its events.
Sponsored by CIENCIA VIVA, it organised a one-week, from June 30 to July 4, hands-on introductory
course on telecommunications for 10th, 11th an 12th grade high school pupils with 20 enthusiastic
participants and an open-lab two hour session for a similar audience.
Also in cooperation with IST, it organised visits and demonstrations for high school pupils, involving
about 800 pupils (in 2015).
During 2015 it continued the regular publication of its monthly newsletter, which is distributed
electronically to all researchers and PhD students, and also continued its presence in social networks
(Facebook, YouTube and Flickr).

Key IT Indicators
2.1
Human Resources
In December 2015 it human resources included 761 people distributed as follows:
• 306 researchers (of which 24 were it grantees);
• 224 PhD students
• 119 other it grantees (84 MSc, 26 BSc, 8 R&D starting grants, 4 R&D integration and 1 R&D
management);
• 11 technical;
• 18 administrative.
All researchers but 2, hold a PhD degree. As a result of the application of it quality policy, out from
the 304 researchers holding a PhD Degree, this is equivalent to 141 FTE (full time equivalent).
The distribution of all human resources between the three sites is represented graphically in Figure
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 scientific productivity in 2015 was 1.6 journal papers per researcher holdind a PhD (or 2.74
journal papers per FTE). Counting each book, bookchapter and journal paper as one publication, the
ratio becomes 1.5 publications per eligible researcher (3.25 per FTE).
It is interesting to compare the distribution of the number of researchers per Site and Branch 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
Branch 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 Branch. 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 15 and 16 are self explanatory, it is interesting to remark that both at the levels of
papers in journals of communications in international refereed conferences, site distribution follows
very closely researchers distribution. Differences are considerable at the number of patents (as
would be expected given the small number of patents involved). Major differences are at Covilhã and
Lisboa ISCTE, the former with more journals papers and the latter with fewer journal papers than
their number of researchers. As far as conference papers, Lisboa ISCTE stands out with a higher share
of output compared to its share of researchers.
Networks and Synergies
it has been trying hard to improve networking not only between its researchers but also with
external researchers. Using it database of journal and conference publications in 2015 figures 18 and
19 were produced representing it co-authorship network in 2015.
In this figure each researcher is represented by a symbol whose colour indicates the researcher
scientific area according to the following colour code:
• Red — Wireless Communications;
• Blue — Optical Communications;
• Orange — Networks and Multimedia;
• Green — Basic Sciences and Enabling Technologies;
• White – External Author.
The nodes´symbol shape is different according to the researcher´s Site. The node size is proportional
to the number of connections originated by each node. The existence of a paper authored by two or
more researchers is represented by a line linking the nodes involved.
The networking strength is apparent in Figure 19. Although most connections involve researchers in
the same scientific area, there is a significant number of connections between researchers of
different scientific areas, a clear indicator of the synergies it is fostering.
On the other hand networking outside the same scientific area is almost non-existing in journal
papers (Figure 18) an indication that long term collaboration between researchers of different areas
and or sites is not yet widespread. However these links start to appear when we carry out the
same exercise accumulating data from more than one year (not shown in this report), an
indication that out of the scientific area collaboration in Journal papers is sporadic but it
exists.

Prototypes for Efficient Energy Self-sustainable Wireless Sensor Networks
Funding
FCT/PTDC
Descript.
The main challenge is the development of an energy self-sustainable wireless sensor
network formed by nodes with energy scavenging capabilities. Body and movement
energy scavenging will be considered whilst maximizing the energy efficiency. One of the
bottlenecks of the wireless sensor devices performance is the batteries and energy
storage. For indoor environments, rechargeable batteries may be the solution, although
recharging the batteries may be burdensome especially for the elderly people. As solar
cells are not viable with body-worn sensor nodes (because sensors are preferred to be
placed under the clothing), motion and body heat based energy harvesting techniques
should be investigated for healthcare and body monitoring systems. The main challenge

Area Network (WBAN) aspects, contributions will be given on the development and
experimental verification of a hardware solution for WSN protocol performance
evaluation. This study relates to the modelling and experimental evaluation of WSN
routing and link layer protocols with no degradation in the sensor nodes performance.
Two contention-based WSN MAC protocols will be compared via modelling, simulation
and hardware experimental measurement approaches. Not only will the energy
spending be addressed, but also throughput, packet delivery rate, and end-to-end delay.
Routing protocols that save energy are also aimed at, and different QoS metrics will also
be considered, trying to reach a solution that uses the least energy possible, while
delivering all the packets with a very low latency. Aspects of hybrid energy storage will
be considered both in the simulations and hardware verification, envisaging the
improvements to be achieved for the network protocol proposal.

VTL PTDC/EIA-CCO/118114/2010
Title
Semáforos Virtuais
Funding
FCT/PTDC
Descript.
Urban transportation is one of the grand challenges of our times. Car journeys are by far
the main player in this transportation, comprising 72% of all passenger kilometers in the
European Union (EU) [1]. Traffic congestion on the road is thus a common reality of the
major EU cities, and has been estimated to cost as much as 1% of the GDP. In its present
form, the use of Traffic Lights (TL) to control and regulate this road traffic has proven to
be very costly and inadequate in terms of scalability. Leveraging the new vehicle-tovehicle (V2V) communication capability of modern cars we propose to design and
validate an alternative scheme of urban traffic control that envisions TL as in-vehicle
virtual signs, enabling ubiquity of signalized intersections, and defining the
synchronization of light phases, cycle durations and green splits based on distributed and
self-organization techniques that govern a vehicular ad hoc network (VANET). The nonscalability of TL, and in particular the non-scalability of an adaptive and intelligent
citywide system of TL (a recent survey reports that 70-90% of the deployed TL are nonadaptive [2]) is a key aspect that we shall address through the alternative approach
40
proposed in this project. Even New York City only has 10,800 of its 45,000 intersections
managed by TL [3]. In other cities this percentage is typically smaller. In addition to
traffic flow improvement, TL have also a significant impact on road safety, as studies
report a 33% decrease in vehicle crashes at intersections that have been equipped with
traffic signals [4]. Our approach in this project will take advantage of the mandatory
adoption by the automotive industry of the Wireless Access for Vehicular Environments
(WAVE) protocol, and the ability of vehicles to communicate with each other, thus
creating a distributed and highly reliable system of in-vehicle virtual traffic lights (VTL).
Our preliminary simulations of this self-organizing traffic paradigm show a potential to
increase the average flow rates substantially (up to 60%, compared with a city-level
physical TL system [5]), in addition to rendering traffic control and management more
ubiquitous and cost-effective. Our basic idea is relatively simple: use the core
characteristics of VANET, namely periodic beaconing, location tables and appropriate
transport and MAC protocols to perceive crossing conflicts and elect a leading vehicle
that works as a temporary virtual infrastructure, stopping under a virtual red light at the
entrance of the intersection and broadcasting virtual traffic light messages that are
listened by the vehicles approaching the intersection. Local optimization of cycle
duration, phase layout and green splits are computed based on the number of vehicles in
each approach. City-level optimization of traffic flow can resort to the synchronization of
leaders in adjacent intersections or even to a traffic information system that also
leverages on VANET communication. Devices on each vehicle interpret the VTL messages
and display the respective color to the driver. We envision the computing,
communication and display device to be possible to retrofit on the existing car park, and
the project will produce such devices. By providing unequivocal evidence of the
envisioned approach on the mitigation of traffic congestion, its economical and
environmental impact, and increased road safety, the project intends to pave the way
for the adoption of EU legislation towards the equipping of all vehicles with VTL. Our
project is a natural follow-up of the DRIVE-IN (Distributed Routing and Infotainment
through Vehicular Inter-Networking) project, funded by the Portuguese Science and
Technology Foundation and involving an international partnership with Carnegie Mellon
University in the US. DRIVE-IN has been designing VANET communication protocols and
developing high-scale traffic models and simulators that will support the design and
validation of the in-vehicle VTL system. DRIVE-IN has also deployed a prototype VANET in
the city of Porto, resorting to 450 taxis where carPCs with windshield displays are
installed, together with 802.11p wifi cards for V2V and vehicle-to-infrastructure (V2I)
communication. This test-bed constitutes a major asset for the research herein proposed
and shall be used for proof-of-concept field experiments in closed areas of the city. The
project is structured in the following four main tasks: 1 – Design of the VTL
communication protocol and distributed optimization of traffic flow. 2 - Security and
reliability of the VTL system. 3 - Human-machine interface of the VTL system and
usability evaluation. 4 - Hardware design for retrofitting and field trial experiments. Our
41
team includes experienced researchers with different backgrounds, including computer
science, computer engineering, civil engineering and mechanical engineering. We
leverage on specific expertise in vehicular networks, intelligent transportation systems,
vehicular human-machine interfaces, wireless networking security and traffic
management.

ICT COST Action IC1104 - Random Network Coding and Designs over GF(q)
Funding
EC
Descript.
Random network coding emerged through an award-winning paper by R. Koetter and F.
Kschischang in 2008 and has since then opened a major research area in communication
technology with widespread applications for communication networks like the internet,
wireless communication systems, and cloud computing. It allows transmitting
information through a network by disregarding any of its topological features. As in
traditional algebraic coding theory, two main research directions in random network
coding are: 1- existence and construction of good and optimal network codes, 2efficient encoding and decoding schemes for a given network code. Restriction to the
so-called Grassmannian codes has proven to be advantageous and leads to the theory of
designs over GF(q). Worldwide, there exists a larger number of workgroups focusing on
this topic, which includes several groups located in Europe. This COST Action will set up a
European research network and establish network coding as a European core area in
communication technology. Its aim is to bring together experts from pure and applied
mathematics, computer science, and electrical engineering, who are working in the areas
of discrete mathematics, coding theory, information theory, and related fields.

Title
Coordinated MultiPoint Strategies for Future Wireless Networks
Funding
FCT/PTDC
Descript.
The main technical objectives of the project are to design, implement and validate
techniques exploring BSs collaboration for future wireless systems. The aim is to design
and demonstrate practical multicell transmission and reception techniques that improve
user’s fairness and throughput, namely at the cell-edges. To reach the above main goals,
specific research objectives are:
42
• Design of practical precoders for the downlink of multicell MIMO-OFDM based
networks. Initially, we will focus on the intra cluster interference. Two approaches are
considered: full centralized, which requires that CSI and data of all UTs are available at
the CU; distributed, where the precoding vectors and power allocation are computed in
a distributed fashion on each BSs. In the second phase a joint precoding approaches will
be designed to remove both intra and inter cluster interference by exploiting the
promising concept of IA.
• Design of efficient multiuser detection techniques for the uplink of multicell MIMO SCFDMA based networks. These receivers will be implemented in the frequency-domain,
based on the IB-DFE concept, eventually taking advantage of the channel decoder
output. The multiuser decoder will be designed taking into account nonlinear effects in
the transmission chain and can involve the estimation and cancellation of those effects.
• Designing of efficient signalling strategies both for the feedback of wireless link
information and distribution among the cooperating network elements, aiming to
optimize the trade-off between achieved performance and signalling overhead.
Moreover, particular emphasis will be placed on inter-cluster feedback and quantization
strategies.
• Design and optimization of medium access control protocols for the considered
clustered multicell architecture with joint scheduling and dynamic link adaptation. The
framework of multi-objective optimization, will be used to find the algorithms that
efficiently allocate radio resources (power, carriers) among the different tiers.
• Assessment and validation of the proposed downlink and uplink algorithms under
realist scenarios, trough a system level simulator based on LTE specification.
• Development of an FPGA based testbed allowing to experimentally show the feasibility
of the proposed algorithms. The most promising algorithms (with good
complexity/performance trade-off) will be integrated and characterized in this testbed.

Title
Millimeter Wave Antennas for Next-Generation Satellite Mass Services
Funding
FCT/PTDC
Descript.
1) Research of new compact Ka-band satellite antenna solutions capable of operating
simultaneously in both uplink and downlink bands. The antennas will be based on the
aperture overlap concept. In one approach an adequate frequency-selective multi-layer
slab is placed above an array of feeds in order to produce multiple overlapping
apertures, each one ensuring adequate reflector illumination. In another approach of the
project, integrated shaped lens antennas with multiple feeds attached to its base will be
43
explored with the same objectives.
2) Design of compact low-cost Ka-band antennas for terrestrial terminals, either fixed or
installed on moving platforms like cars, trains or ships. These antennas must have a
single steerable beam constantly pointing towards the satellite as the terminal moves.
This will evolve from a previous concept proposed by the project team, where a
steerable shaped dielectric lens pivots in front of a stationary feed requiring no rotary
joints which are expensive and prone to faults. New lens configurations will be
researched, including flat lens made of inhomogeneous metamaterial.

Thermal Blanket with Low RF Reflectivity
Funding

Descript.
The primary objective of this study is to propose a series of concepts based on
metamaterials in combination with the typical materials used in thermal blankets in
order to reduce the blanket’s RF reflectivity in specific frequency ranges. Concepts will
be explored at the C-, Ku, Ka and Q/V bands. The new blankets are required to maintain
their thermal and mechanical properties as much as possible and be designed with space
flight in mind using space qualified clean-room compatible materials. Further
requirements include cost effective fabrication compatibility, and reduced added mass
compared to traditional multi-layer blankets.

Title
Transformation Electronics and Optics
Funding
FCT
Descript.
We propose three major research lines:
• Tailoring the electron mass and the transport properties – In a semiconductor the
effective mass determines the inertia of the electron to an external stimulus. The finite
value of the mobility ultimately limits the speed of integrated circuits and other devices.
In most electronic circuits the electron flow is supposed to occur along a predetermined
44
path, e.g. down the passageway connecting two transistors. However, typically only a
small fraction of the available free carriers responds effectively to an external electric
field. We want to show that based on the superlattice concept it may be possible to
engineer the electron mass tensor in such a way that (i) all the available electronic states
contribute to the electron flow. (ii) the intrinsic electron resistance to movement is
greatly reduced. In addition, these ideas may enable to boost the electrical conductivity.
• Tailoring the nonlinearities in graphene and semiconductor superlattices and in
electromagnetic metamaterials – Nonlinear electromagnetics (in particular nonlinear
optics) has important applications in frequency multiplication or high-speed data
transmission based on solitons. However, the nonlinear response of most natural
materials is extremely weak. Previous studies have shown that by tailoring the electronic
structure it is possible to enhance the nonlinear response. Here, we suggest boosting the
nonlinear response by decreasing the intrinsic resistance of the electron to movement in
engineered semiconductor or graphene superlattices. Our objective is to develop novel
electronic materials with enhanced nonlinear response, and in addition to characterize
the solitons supported both by these structures and by more conventional
electromagnetic metamaterials based on metallic nanowire arrays.
• Effective medium theory – Effective medium theories are of key importance in the
study of “low energy” physical phenomena since they enable reducing the inherent
microscopic complexity of a physical system to a few effective parameters. Despite the
fundamental differences between photons and electrons, there are many formal
similarities between photonics and electronics, which ultimately result from the waveparticle duality. However, the theoretical frameworks typically adopted to describe wave
propagation in electromagnetic media and in semiconductors are usually rather
different. As a generalization of our previous studies in the context of electromagnetic
metamaterials, we propose to develop a general effective medium framework based on
the Hamiltonian formalism that enables describing “macroscopic excitations” in both
electromagnetic metamaterials and semiconductor and graphene superlattices. Such
common framework will enable establishing straightforward analogies between
electronics and photonics.

the development of cognitive radio devices will be far more complex than that of their
predecessors. Large, interdisciplinary development teams are required to cover areas
such as analog RF hardware, digital hardware design, digital signal processing and system
architecture. With the research team selected for this project we believe to have put

One of the most promising emerging medical imaging modalities is Microwave Imaging
(MWI), which is a low-power, low-cost, non-ionising imaging modality and also has
therapeutic capabilities. Most of this MWI research to date has been accomplished in
simulation and laboratory studies, with only limited translational research into the
clinical environment. European researchers have been at the forefront of the
development of MWI. With respect to medical applications, these (mostly independent)
efforts have lead to the design of several microwave-based imaging devices, most of
which are currently undergoing or poised for clinical trials. Such a reserve of knowledge
constitutes a unique opportunity for European researchers to leverage existing
experience and expertise to streamline the transition from simulation/phantom testing
to full clinical trials and clinical adoption of MWI devices. Collaboration will provide a
valuable non-competitive framework which will provide European researchers with the
necessary structure and support to overcome common challenges and bring MWI from
“research bench to patient bedside” in a much shorter period of time, boosting the
European Research Area and its excellence in a worldwide context. Experience in the
commercial evaluation of MWI devices will also be shared amongst COST participants.

Enhanced Underwater Acoustic Receiver Design for MIMO Communications
Funding
FCT
Descript.
The underwater world offers an immense space with an enormous potential, especially
for a country as is Portugal that has one of the biggest marine zones in Europe (Exclusive
Economic Zone, the 3º largest in Europe and 11º largest in the world). A fundamental
part for withdrawing the full potential of this natural resource is to solve the problem of
47
high-bandwidth underwater communications.
This project aims to develop signal
processing schemes that will enable for high bandwidth underwater acoustic (UWA)
communications using aggregates of sources and hydrophones (Multiple Input, Multiple
Output - MIMO) between mobile emitters and receivers. In radio communications,
MIMO systems allows for considerable gains in the transmitted throughput and
reliability, what has recently made several research groups to consider them for UWA.
However, the propagation channel in UAC has characteristics substantially different than
that of radio channels; since it has a high variability in both time and frequency (i.e., the
channel is doubly selective). Besides that, the noise presents impulsive characteristics,
for which the normal Gaussian model is inadequate. So being, the use of techniques for
the normal radio channel without specific modifications would give rise to high
performance degradation in UAC. This being, the main purpose of this project is to
develop and assess the performance of transmission techniques for MIMO-UWA
systems. The project will begin by selecting relatively simple channel models to account
for the doubly selective specificities of the doubly selective UWA channel model.
Adequate models to characterize the impulsive noise specifications of the channel will
also be selected, in order to permit adequate analytical processing. Afterwards, special
transmission techniques specially designed for MIMO-UWA will be developed. These
techniques will be based on MIMO-OFDM (Orthogonal Frequency Division Multiplex)
and MIMO SC-FDE (Single Carrier- Frequency Domain Equalization) [BFDT10], combined
with IB-DFE (Iterative Block-Decision Feedback Equalizer)
[Benvenuto_Dinis_ProceedingsIEEE2010]. The channel will be estimated by taking
advantage of Delay-Doppler Spread Functions (DDSF) [ZGB10_2]. We will exploit the
sparsity of DDSFs for the envisaged patterns of motion and their spatial correlation to
derive fast MIMO estimation methods using basis pursuit, as well as techniques to
compensate for deviations of the carrier’s frequency (CFO – Carrier Frequency Offset)
[PDN10]. In the case of OFDM modulation, techniques to reduce the PAPR(Peak-toAverage Power Ratio) will be employed based on non-linear devices [DG04, DSA09], so
that a greater amplification efficiency can be attained, as well as adequate receivers for
non-linear systems [Guerreiro2012,Guerreiro2013]. The developed MIMO systems will
be validated with realistic Matlab simulations, a program yet to be developed and
adapted with blocks already implemented by the different persons of the research team.
This program will serve as a demonstrator/ prototype for the project.

of techniques that enables efficient coexistence of heterogeneous systems (macro and
smallcells). The aim is to design and demonstrate practical joint cooperative and
cognitive transmission/reception techniques to improve the user’s fairness and
throughput of the entire network. The specific objectives include: •Design linear

inter-systems (smallcell/macrocell) interferences. We consider that some terminals are
equipped with cognitive capabilities to efficient design the precoders, namely the ones
used to mitigate the inter-system interference.
•Design joint precoding and detection techniques for uplink to mitigate both intra/intersystem interferences. The aim is to combine the interference alignment with efficient
equalization schemes (e.g. IB-DFE based ones).
•Design efficient signaling strategies both for the feedback of wireless link information
and distribution among the cooperating network elements, aiming to optimize the tradeoff between achieved performance and signaling overhead. Moreover, particular
emphasis will be placed on inter-system feedback and quantization strategies.
•Assessment and validation of the proposed downlink and uplink algorithms under

•Development of an FPGA based testing infrastructure allowing to experimentally show

Title
Generalized Linear Amplification with Nonlinear Components for broadband wireless
systems
Funding
FCT
Descript.
Broadband wireless systems require high power and spectral efficiencies, and
transmission over severely time-dispersive channels. In this research theme we consider
the design and implementation of digital transmission techniques with high power and
spectral efficiency to be employed in the uplink of mobile systems or in satellite
communications. We consider SC-FDE techniques (Single- Carrier with FrequencyDomain Equalization) combined with powerful IB-DFE (Iterative Block Decision Feedback
Equalizer) receivers [Ben10]. Our main goal is to design signals with low PAPR (Peak-toAverage Power Ratio) or even quasi-constant envelope and high spectral efficiency and
employ amplification techniques based on low-cost, highly efficient grossly NL
(NonLinear) amplifiers (e.g., class D and E amplifiers), which are simpler and have higher
amplification and output power than quasi-linear amplifiers [Rey06]. Two approaches
will be followed. The first one uses LINC techniques (Linear amplification with Nonlinear
Components) [Cox74], where a variable-envelope signal is decomposed as the sum of
two constant-envelope signals, which are separately amplified without distortion by two
NL amplifiers. Although LINC techniques seem an efficient solution for our problem, they
have the following problems: -The power amplification efficiency reduces with the PAPR
of the signals at the LINC input; -The LINC decomposition is performed on a sampled
version of the signals and the oversampling requirements can be very high, mainly due
to signals’ zero crossings; -The two amplifiers must be perfectly matched, since
amplifiers’ unbalances lead to performance degradation and out-of-band radiation. To
maximize amplification efficiency we use MM (Magnitude Modulation) techniques
[Tom02, Gom09, Gom10] so as to reduce the PAPR of the signals at LINC input.
Appropriate MM techniques will be developed so as to avoid zero-crossings and the IB-
51
DFE receiver will be designed taking into account the adopted MM schemes and
eventual residual amplifier unbalances. The impact of phase and gain mismatches on
performance and out-of-band radiation will be studied to define amplifiers’ matching
requirements. The second approach is less orthodox and takes advantage of the
following: -A given constellation can be decomposed as the sum of binary components
[Din10]; -The complex envelope of OQPSK (Offset Quadrature Phase Shift Keying) signals
at an appropriate frequency can be regarded as BPSK signals [Amo77]; -OQPSK signals
can have quasi-constant envelope. Therefore, a given constellation can be decomposed
as the sum of several constant-envelope BPSK (or OQPSK) components that can be
separately amplified without distortion by different NL amplifiers, as in LINC
transmitters, but without oversampling requirements. One problem with this approach
is that the band of constant envelope BPSK/OQPSK signals is much wider than the
minimum Nyquist bandwidth. For this reason, we replace each BPSK/OQPSK component
by an OQPSK-type signal (which is also the sum of OQPSK terms) specially designed to
have quasi-constant envelope and good spectral characteristics [Mon10]. This approach
is suitable for somewhat loose spectral restrictions. If not, we separate different
frequency channels to the minimum Nyquist band and design FDE receivers able to cope
with strong ACI levels (Adjacent Channel Interference) by combining the techniques of
[Din05,Luz09] with receivers specially designed for offset modulations [Mar09,Luz12].
With this approach, amplifiers’ unbalances do not lead to out-of-band radiation,
however they can lead to performance degradation. The proposed techniques will be
studied both analytically and by simulation, to check the potential and limitations of
each one, taking into account achievable performance, spectral efficiency robustness
and complexity issues. The main contributions of this project are the following: -Design
of OQPSK-type signals with quasi-constant envelope and good spectral characteristics; Design of MM schemes specially designed to be combined with LINC-type techniques,
namely to reduce the oversampling requirements; -Design MM schemes for offset
modulations and different pulse shapes; -Design of linear amplification schemes for
general constellations that employ multiple (more than two) grossly NL amplifiers; -FDE
design of MM and OQPSK-type schemes, with or without ACI, eventually taking into
account residual amplifiers’ mismatches; -Definition of matching requirements for multiamplifier techniques; -Validation and system simulation for most promising techniques;

Memory-Effects Compensation in GaN Power Amplifiers
Funding
FCT
Descript.
Nowadays, it is unquestionable that communication systems play a very important role
in our daily routine. Wireless systems, in particular, are growing in such a way that
people have difficulty living without the services already available. This being the case,
any big change, or improvement, in terms of power consumption in these systems will
certainly have a big impact on what the available resources usage is concerned.
Moreover, it is not acceptable that technology uses more and more resources in an
unthinkable way without trying to be as efficient as possible. This project comes exactly
in this direction as it tries to push further state-of-the-art systems that, unfortunately,
have their own problems inherent to their infancy. Having that in mind, this project is
focused on the design and implementation of a memory-free wireless transmitter built
with GaN transistors. It is undeniable that this technology was a breakthrough in what
efficient and available power are concerned. Unfortunately, it still suffers from several
53
problems that are yet to be solved. Therefore, the above referred main objective of this
project can be tackled according to the following different, but interrelated, goals: (i) It
is recognized that, for understanding something in nature, first we need to carefully
characterize it. In what memory-effects in GaN transistors are concerned the
methodology has to be the same. So, the objective is to fully characterize them using a
set of reference measurements such as: - static and dynamic AM/AM and AM/PM
amplitude sweeps; - step-up and step-down output power and phase measurements
going from small- into large-signal regimes; - S-parameters for the bias circuitry and
matching networks characterization. (ii) Modeling memory-effects in commercial
computer added design simulators making it possible to replicate, in a virtual
environment, the real operation of the device and search, in a more flexible way, for the
necessary solutions. (iii) Correct the memory-effects (short- and long-term) visible in
todays’ power amplifiers and prove it with a complete prototype implementation.

measurement facilities available at IT, particularly for a multi-frequency measurement
system capable of measuring channel impulse response, in addition to the dynamic
effects, including Doppler spectra for each individual multipath component, of doubly

The main goal of this project is to advance the state-of-the art on physical-layer
techniques to secure wireless networks under eavesdropper adversaries that aim to
overhear unintended information. The almost-permanent connectivity of people and
things to the Internet that we are currently approaching poses several security and
privacy challenges, such as how to assure confidentiality in spontaneous networks of
unknown users/devices, where key-exchange is deemed difficult. Physical-layer security
is gaining interest as a means to provide an extra layer of security that does not depend
on the traditional cryptographic key-exchange, but takes advantage of the inherent
varying characteristics of wireless channels to establish secure communication. In this
work, we plan to develop, implement and evaluate practical physical-layer security
techniques based on coding and spread spectrum methods. In particular, we plan to
develop interleaving for secrecy mechanisms, where the access to a degraded version of
the interleaving key acts as the source of advantage over an adversary eavesdropper.
Moreover, to provide periods of advantageous communication for interleaving key
exchange, we shall develop spread spectrum frequency-hopping mechanisms combined
with jamming over eavesdroppers and tailor the operation of such mechanisms to
provide the highest possible advantage over the eavesdropper. The developed
60
techniques shall form the basis for more evolved physical-layer security schemes, such as
combined with cognitive radios – intelligent radio interfaces that can be programmed

wireless technologies, and better load balancing across available spectrum. SPEED-5G
will investigate indoor and indoor/outdoor scenarios where capacity demands are the
highest, but also where the eDSA will be the most effective at exploiting co-operation
across technologies and bands. The project will focus on two major innovations which
are currently missing: resource management techniques across technology ‘silos’, and
medium access technologies to address densification in mostly unplanned environments.
It will leverage flexible radio approaches expected in 5G (e.g. FBMC). SPEED-5G has a
very strong consortium, with a mix of operators, industrial partners, SMEs and leading
European research institutes. They bring considerable knowledge and technology
background to the project in architecture, resource management, protocols, radios,
standardization, trials and tests, along with the most advanced of trial facilities, like the
5GIC centre. The SPEED-5G innovations will be considered in an architectural framework
consistent with the 5GPPP. They will be researched, implemented and trialled in SPEED5G in order to reach high level of maturity and confidence. This will guarantee impact on
the 5GPPP program as a whole, on standards and on European technical leadership.

ANACOM-URSI Portugal Prize was assigned to “Diffractionless Propagation of Electron Waves in
Graphene Superlattices”. In this work we used a homemade Finite Difference in the Time Domain
(FDTD) algorithm to characterize the propagation of electron waves in graphene. The algorithm was
applied to study the dynamics of electrons in graphene superlattices, using both microscopic and
102
effective medium approaches. In particular, it is shown that the time evolution of an electronic state and
the propagation of stationary electronic states may be accurately predicted with the effective medium
formalism, provided the initial state is less localized than the characteristic spatial period of the
superlattice. Our results confirmed that electrons propagating in graphene superlattices with extreme
anisotropy experience virtually no diffraction, 01-12-2015

4.2.3 Summary of Research Achievements
4.2.3.1
Optical components and sub-systems
4.2.3.1.1 Quantum communications
•
We demonstrated experimentally the feasibility of a two-state quantum bit commitment
protocol, which is both concealing and partially binding, assuming technological limitations. The
security of this protocol is based on the lack of long-term stable quantum memories. We used a
polarization-encoding scheme and optical fibre as a quantum channel. The measurement
probability for the commitment is obtained and the optimal cheating strategy demonstrated.
Using a strict numerical validity criterion, we show that, for the obtained experimental values,

Signal processing for high-bit rate optical communications
•
•
We proposed a novel closed-form time-domain (TD) Volterra series nonlinear equalizer (VSNE)
for the mitigation of Kerr-related distortions in polarization-multiplexed (PM) coherent optical
transmission systems. In order to enhance the computational efficiency, we insert a power
weighting time window in the TD-VSNE, yielding the weighted VSNE (W-VSNE) algorithm.
Through numerical simulation of a 224-Gb/s PM-16QAM optical channel, we compared the
performance/complexity trade-off of the W-VSNE with the well-known split-step Fourier
method (SSFM) and with the computationally optimized weighted SSFM (W-SSFM). The W-VSNE
achieved a reduction of up to∼45% on computational effort and ∼70% on latency, in
comparison with the W-SSFM.
We demonstrated fully blind processing and reduced complexity nonlinear equalization (NLE) of
a 100G PM-64QAM optical channel in a 50 GHz WDM grid, achieving a maximum reach of 1524

km over pure silica core fibre at a bit error rate of 2.7 × 10−2. Applying a simplified Volterra series
nonlinear equalizer (simVSNE), operating in the frequency domain, we demonstrate a reach
extension of ∼27% relatively to linear equalization.
We studied experimentally an adaptive polarization demultiplexing (PolDemux) technique. The
applicability of the adaptive Stokes algorithm was tested in an ultra dense wavelength-division
multiplexing scenario over 80 km of standard single-mode fibre. The BER results showed a very
small power penalty confirming the suitability of the adaptive Stokes method in systems where
the accumulated chromatic and polarization-mode dispersion are small, such as high capacity
optical metro and access networks scenarios.
We applied an extended Kalman filter to Stokes space-based polarization demultiplexing for
complex-modulated signals. The convergence ratio, tracking, computational complexity, and
system performance of this method were investigated and compared with the geometrical
approach previously proposed. An analysis of the tuning parameters of both methods reveals
that the Kalman filtering provides a more robust and stable polarization demultiplexing of
signals. Nevertheless, if properly tuned, the geometrical approach attains a similar performance,
with a gain of 90% in terms of complexity reduction

Mode-division multiplexing requires all-optical signal processing techniques that are able to deal

potential highly non-linear and multi-modal waveguide for all-optical signal processing devices
to be used in mode-division multiplexing systems based on the four-wave mixing process. The
inter and intramodal phase-matching conditions for the four-wave mixing process were mapped
as a function of the micro wire diameter and the wavelength of signals. Moreover, the efficiency
of four-wave mixing considering a strong guiding regime was investigated in the multi-modal
regime.
We proposed an in-line wavelength selective core switch for multicore fibre (MCF) transmission
systems, based on the acousto-optic effect. A theoretical model addressing the interaction
between flexural acoustic waves and the optical signal in MCFs was developed. We showed that
an optical signal propagating in a particular core can be switched to any other core or
distributed over all the cores. By tuning the acoustic wave amplitude, we can adjust the amount
of optical power transferred between the cores.
We studied theoretically and experimentally the viability of using Long Period Gratings (LPG) in
multicore fibres (MCFs) as a solution to develop different components. We proposed the use of
identical LPGs inscribed on a four-core fibre to promote the power transfer between all the
cores evenly, which can be used to distribute a single pump to all the cores. We also studied the
power transfer between identical cores of heterogeneous MCFs as a first step towards the

We analyzed the capital expenditures (Capex) and operational expenditures (Opex) related to
the power consumption and footprint requirements of fixed and flexible node architectures in a
multiperiod scenario and under different traffic requirements. Results show that in spite of the
initial higher investment required by flexible architectures, in the long term they tend to present
lower Capex and Opex.
We proposed new dimensioning models for transport network nodes taking into consideration
the multiplexing/grooming architecture. Using the developed models, we analyzed the impact of
node architecture flexibility in the number of line interfaces required, and assessed the potential
savings attained by exploiting hitless re-grooming. Results show that enhanced flexibility
produces more savings when the client traffic bit rate is much smaller than the line bit rate.
We analyzed the shortest path lengths between node pairs of real optical transport networks.
From the analysis, we found that Johnson SB distribution is suitable for the shortest path length
modelling. We also showed that the key parameters of the shortest path lengths, such as the
mean, the median, and the standard deviation, can be estimated from the convex area of the
network. It is noteworthy that these estimations can be made without full knowledge of the

concept aims at extending the number of users of the NG-PON2 (Next Generation Passive
Optical Networks 2) technology, increasing also the data rate up to at least 2.5 Gbps dedicated
per end-user in the downstream and upstream directions.
• A new paradigm for future OANs has been demonstrated in a field-trial, where multiple existing
PON technologies (including the new NG-PON2 technology) coexisted with the new UDWDMPON technology. This experiment was validated in real-time in September 2015, with an installed

Descript.
Wireless transmission via optical carriers opens doors of opportunity in areas as yet
largely unexplored. Offering significant technical and operational advantages, optical
wireless communication (OWC) can be, in some applications, a powerful alternative to
and, in others, complementary to existing radio frequency (RF) wireless systems.
Variations of OWC can be employed in a diverse range of communication applications
ranging from very short-range (on the order of millimetres) optical interconnects within
integrated circuits through outdoor inter-building links (on the order of kilometres) to
satellite links (larger than 10,000 kilometres). In many respects, OWC research is still in
its infancy and calls for extensive research to begin to harness the enormous potential of
the optical spectrum. This COST Action will serve as a high-profile consolidated European
scientific platform for interdisciplinary OWC research activities, spanning from
characterization of diverse propagation media to modeling, design and development of
devices, components, algorithms/protocols and systems. It will make significant
contributions to the fundamental scientific understanding, technical knowledge,
engineering design and applications while promoting community awareness of this
emerging field. Development of novel and efficient communication technologies
resulting from integrated research activities made possible through this Action will be a
significant enabler for future-generation heterogeneous communication networks
supporting a wide range of wireless services/applications.

Metro Networks Based on Multi-Band Orthogonal Frequency-Division Multiplexing
Signals
Funding
FCT/PTDC
Descript.
The general objective of this project consists in demonstrating the new paradigm related
to the increase of the flexibility and granularity of the transmission capacity in
metropolitan (metro) optical networks. Particularly, the implementation of metro
networks based on high data-rate multi-band orthogonal frequency-division multiplexing
(MB-OFDM) signals employing wavelength division multiplexing (WDM) is analysed and
demonstrated as an excellent solution to provide, simultaneously, high flexibility in
capacity allocation, high spectral efficiency and the possibility of upgrading the network
capacity while keeping the system architecture almost unchanged. Recently, optical
transmission systems with high capacity granularity have been appointed as the most
promising solution to be employed in the integration of the metro and access networks
in a single hybrid optical network. Systems based on MB-OFDM signals have been
recognized as an excellent solution as they allow the integration of several final users
who usually require a capacity quite below the total network capacity. This access
technology has been indicated as a good alternative to the solutions based on timedivision multiplexing currently deployed. Previous works have experimentally shown the
dynamic allocation of OFDM subcarriers or individual bands of MB-OFDM signals as an
excellent solution to increase the granularity of capacity allocation. However, these
works were presented as a proof-of-concept: the MB-OFDM transmission impairments
and the traffic allocation optimization were not analyzed. In addition, the main
performance limitations were not identified as well. This project has two particular
objectives. First, it is focused on the investigation of the performance impairments
imposed by the physical layer on the high data-rate (maximum bit rate of 40 Gbit/s per
wavelength) MB-OFDM signals transmission in WDM metro networks and on the system
parameters optimization using analytical, simulation and experimental work.
Particularly, the study and the assessment of the main system impairments is performed,
such as: (i) linear crosstalk associated with the MB-OFDM transmission and with the
finite selectivity of the optical devices required to select the different bands and
wavelengths at each node of the metro network, (ii) linear and nonlinear fibre effects,
(iii) joint nonlinear effect introduced by the electro-optic and opto-electric conversion
processes. Second, this project is focused also on the study of the network layer of WDM
metro networks based on MB-OFDM signals. Particularly, the assignment of OFDM
bands and wavelengths, and the traffic distribution along the network are analysed.
Routing, wavelength and band assignment (RWBA) algorithms are developed based on
maximum wavelength and band reuse in MB-OFDM metro networks. These algorithms
are developed considering the impairments imposed by the physical layer of the WDM
MB-OFDM metro network (cross layer design). The work to carry out along this project is
118
focused on MB-OFDM signals with intensity modulation - direct detection (IM-DD)
systems for transmitter and receiver cost reduction, an imperative of metro networks.
Different MB-OFDM transmitters are analysed, e. g. MB-OFDM transmitters using single
sideband modulation implemented using appropriate (I,Q) modulators or the generation
of electrical MB-OFDM signals with adequate properties to provide strong robustness to
fibre dispersion induced power fading. The ultimate goal of the project consists in the
experimental demonstration of the simultaneous transmission of, at least, three optical
channels using MB-OFDM signals in a metro optical network with insertion/extraction
capabilities at the OFDM band level.

Title
Digital Nonlinear Equalization in Very-High Speed Coherent Optical Transmission Systems
Funding
FCT/PTDC
Descript.
The exponentially growing traffic demand in optical core networks has exhausted the
single-mode fiber capacity within the linear regime. We aim to develop efficient digital
equalization strategies in order to counteract the signal distortion imposed by fiber
nonlinearities, in very-high speed (>= 100 Gbit/s/ch) and ultra-dense (>= 4 bit/Hz) multiwavelength coherent optical transmission systems. Building on our previous work and
experience on this topic, we aim to optimize some of the currently proposed algorithms,
mainly in terms of computational requirements, and to develop new solutions for
nonlinear digital equalization in optical fiber systems. Our efforts include the extension
of nonlinear equalization to polarization-multiplexing and WDM transmission. We will
119
focus a great deal of our attention into the problem of inter-channel nonlinear
equalization, developing efficient and moderate complexity techniques to partially
mitigate cross-phase modulation (XPM) and four-wave mixing (FWM) distortions. We
plan to develop simplified approaches to enable adaptive equalization of XPM resorting
to either blind or data-aided equalizers. We also plan to explore artificial neural
networks (ANN) techniques for fiber impairment mitigation. Given the hardware
implementation advantages of ANNs due to their inherent parallel nature, we expect to
obtain efficient real-time implementation solutions. During the last couple of years, the
interest on few-mode fibers (FMF) and mode-division multiplexing (MDM) has exploded,
with numerous publications in major international conferences and journals. This sudden
revival of multi-mode signal propagation is closely related with the need to reduce the
effect of fiber nonlinearities, which is thereby achieved by increasing the fiber core area.
From the digital signal processing (DSP) point of view, the adoption of MDM requires an
extra effort to implement multiple-input-multiple-output (MIMO) equalization of intermodal transmission and coupling. Although signal impairments in FMFs are currently
assumed to be mostly caused by linear processes, some pioneering works are already
exploiting the impact of nonlinearities in FMFs. A timely development of nonlinear
equalization techniques for MDM signal transmission is therefore of utmost importance.
Within this topic there are still many problems to be tackled, ranging from development
of modeling numerical tools for nonlinear signal propagation to the development of
lower complexity digital equalization techniques. We propose to exploit the reported
potentialities of the Volterra series transfer function, extending its scope to MDM
transmission, therefore providing a powerful numerical tool for the analysis and
compensation of inter-modal nonlinearities. The development and optimization of digital
equalization algorithms must be accompanied by meaningful assessment through simple
and accurate figures of merit. We propose to develop simple figures of merit for BER
gain and required computational effort for nonlinear equalization algorithms under
different propagation conditions. These figures of merit should guide the development
of new equalization algorithms and the design of new very high-speed and ultra-dense
transmission systems. Finally, we aim to finalize this project with an experimental test
and validation stage, composed by two implementation phases: offline validation of the
proposed algorithms recurring to experimental data, and hardware implementation in a
field programmable gate array in order to test real-time operation. This implementation
stage will benefit both from IT facilities and expect investment in coherent optical
systems and from a well-established international cooperation with top-level European
laboratories. Given the current absence of feasible solutions for the equalization of
critical nonlinear fiber impairments, we will have the opportunity to generate crucial
contributions to the state-of-the-art of coherent optical systems. In fact, solving the
nonlinear limitation on fiber capacity has been identified as one of the key scientific
breakthroughs to enable future Terabit optical channels.

Phase conjugated twin waves to unlock the potential of future spatial division
multiplexed systems (TWave)
Funding
FCT/COMPETE/FEDER
Descript.
Single-mode fiber (SMF) transport systems are rapidly approaching the Shannon´s
limit,pointing to fiber capacities of no more than 100 Tbit/s, corresponding to filling the
C and L EDFA bands at a spectral efficiency of 10 bit/s/Hz. This limit can be derived from
an extension of the Shannon capacity limit to a nonlinear fiber channel, since the fiber
Kerr nonlinearity leads to distortion when the signal power is increased to achieve
sufficient Signal-to-Noise Ratio, the ultimate limit resulting from the interaction between
amplified spontaneous emission and nonlinearity, which is not deterministic. This may
still be not be enough to answer the capacity requirements in the near future which
points to spectral efficiencies of 20bit/s/Hz over ~1500 km links, associated with the
current growth in capacity of fiber-optic communication systems. Over the last decades,
the steady progress in optical transmission systems was enhanced by the exploitation of
the several properties of electromagnetic waves, namely time, phase, frequency and
polarization. Since 2010, the research community has generally agreed that optical
transport systems will have to resort to the last remaining physical dimension (space) by
employing spatial division multiplexing (SDM), which has the potential to substantially
increase optical transport capacities. Although SDM was first proposed in 1979
(considering MCF) and 1982 (considering MMF), the current progress is occurring now
due to a convergence of technological capabilities (fiber fabrication methods, mode
control and analysis methods, coherent detection and digital compensation) and the
mentioned emerging necessity. The main challenge in SDM occurs due to crosstalk
between pathways, which is typically small for MCF and high for MMF. For MCF the
crosstalk depends on core number, spacing and arrangement, while for MMF the modes
are prone to randomly couple during propagation, with different differential mode group
delays (DMGD). This requires multiple-input multiple-output linear equalization
techniques, similar to the signal processing techniques used for polarization demultiplexing, which poses computational complexity concerns when considering
equalization for long haul mode division multiplexed (MDM) systems. However, similarly
122
to SMF based modern telecommunication systems, the nonlinear penalties in MDM
systems will eventually become the ultimate limiting factor. In this project we propose to
explore the concept of phase conjugated twin waves (PCTW) in SDM optical systems,
which has recently been proved to cancel out signal-to-signal nonlinear interactions in
single-mode fibers by coherently superimposing of a pair of phase-conjugated twin
waves, as a means to overcome the nonlinear impairments arising in mode division
multiplexed systems, in a practical and sustainable way, paving the way for optical
transmission capacities beyond next-generation systems.

Title
ScalaBle & Low-Power Microwave Photonics for FlexiblE, TerAbit Telecom Payloads &
High-speed Coherent Inter-satellite LiNks
Funding
EC/FP7
Descript.
Telecom satellites are growing like giants employing multiple beams to provide high
speed connectivity and broad coverage. Under exploding capacity requirements, vendors
admit that a technology and payload architecture switch is mandatory. The new
technology has to deliver practical, low-power and scalable components with high
performance under harsh environment conditions. BEACON aims to provide this
technology and disrupt the transition to multibeam Tb/s satellites. Addressing cost,
performance and volume, BEACON invests on the right mix of 3 photonic technologies
used in terrestrial telecommunications, i.e. GaAs, Si and doped fibres and combines
them to deliver a compact optical beam-forming technology delivering the massive
amount of bandwidth. BEACON develops ultra-linear GaAs Mach-Zehnder Modulators
(MZM) exhibiting >75dB spurious free dynamic range, 15dB higher than conventional
MZMs. MZMs will exhibit: up to 35GHz frequency operation matching Ka-band
frequency plans and 1/2 the size of mainstream LiNbO3 MZMs. 6’’ GaAs wafers enable
high volume production. BEACON integrates and co-packages 4xMZM arrays with new
packaging method. BEACON develops the first scalable multi-core rad-hard erbium
doped optical fibre amplifier (EDFA). The EDFA employs new radhard doped
microstructured fibre and enabling: >50% electrical power consumption reduction than
using conventional EDFAs and small form factor packaging. BEACON integrates an
innovative photonic beamformer (BFN) using CMOS compatible silicon photonic
fabrication together with Ge diodes. The BFN chip consumes <7.5-times less chip area
than lowindex contrast BFNs. It allows 4 orders of magnitude faster beamsteering.
BEACON integrates the system with BFN control and antenna array to demonstrate that
the technology can scale to Tb/s capacities with considerable savings in size/power
against current kW consuming systems. Component space assessment will guide the
124
technology towards fully space qualified systems.

4.3.3.2
Information and networking theory
The activities on the field of information and networking theory cover a large set of aspects.
4.3.3.2.1
Information theory
Several strand were pursued here:
− Combination of logics: substantial advances in the understanding of fibred logics were
achieved, obtaining full characterizations of conservativity and decidability preservation
results in the disjoint case, and several partial results in the general case, namely using
appropriate notions of translation
− Compositional meaning in logic: suitable generalized notions of compositional meaning in
logic were explored, namely in the context of non-deterministic logical matrices, and
obtained several new characterization
− Computation with real numbers and complexity: the physical measure associated to the
(geometric) Lorenz attractor was shown to be computable, as well as how computational
complexity can be properly defined over analog models of computation like Shannon's
General Purpose Analog Computer.
4.3.3.2.2 Complex Networks
Work in this area covered:
− Theoretical and experimental study of complex networks’ design, structure and dynamics with a
focus on its impact on resilience and robustness properties.
− Study of emergent structures in social conflict scenarios, with applications on a testbed for the
simulation of confrontation with network effects.
− The formulation of a theorem that equates the correctness of routing vector protocols, such as
157
BGP, to a property of routing policies around the cycles of a network and its application in the
derivation of guidelines for the configuration of routers.
− Development of a unified framework to reason about link-state routing protocols, such as OSPF
and IS-IS.
4.3.3.2.3 Global Navigation Satellite (GNSS)
Several research activities were developed in the area of signal processing for GNSS receivers, covering
new algorithms for the detection of interference (non-intentional and jamming) in GNSS, and algorithms
for the efficient simulation of Ionospheric Scintillation effects in GNSS signals.
4.3.3.3
Theoretical and Applied Security
The area of security has seen large developments in the last years inside the line of Networks and
Multimedia.
4.3.3.3.1 Criptography and quantum information
Work was developed on Bit-string oblivious transfer (addressing a quantum computationally secure
protocol for bit-string oblivious transfer between two parties); Blind signatures and PK (quantum blind
signature perfectly secure, and a quantum public key cryptosystem); and quantum multiparty dense
coding (allowing the sharing of information among several quantum agents).
4.3.3.3.2 Security foundations
Theoretical work has obtained decidability and complexity results for an equational-based probabilistic
logic, and started exploring a related NP-complete problem generalizing probabilistic satisfiability
(PSAT).
A detailed technical framework (based on the notion of distributed security setting, and that unifies
previously studied properties such as Distributed Noninterference, Distributed Non-disclosure and Flow
Policy Confinement) was developed for addressing the problem of enforcing information flow security in
client-side web applications.
4.3.3.3.3 Internet Security
The group has worked on a world-wide distributed probing methodology to detect traffic routing
variations. Upon detection, a corporate customer cannot act in terms of Internet-scale routing but can
warn its network service providers and request consequent actions.
This work was further complemented by the development of a formal model for Netfilter for
specification and verification of firewall policies. Furthermore, an efficient and non-intrusive algorithm
158
for detecting performance anomalies in multi-tier virtualized services running in datacenters was
developed.
On different lines, two prototypes of mobile applications integrating cryptography primitives were
developed, including a complete suite of services for securing communications and storage on mobile
devices. Also, some work was performed on practical physical layer schemes for security. Research was
also made on the application of artificial models of immune systems in computer network security.
4.3.3.3.4 Acess Control
In relational database applications, access control is traditionally enforced by security layers based on
centralized architectures. Work has been developed on security layers based on distributed
architectures, which has also been extended to support NoSQL databases.
The authentication problem was also addressed on smartphones, using User Behavior Modelling.
4.3.3.3.5 User Behavior Modeling
Social networking services have emerged as an extremely popular platform for social interactions and
created a new human communication paradigm. We developed a novel continuous time model based
on a multi-ON-OFF Markov chain with exponential truncated sojourn times that is able to fully describe
the sojourn times of different activity and non-activity periods, as well as the rate of interactions on a
social network during the activity periods.
This led to developments as a new means to authentication on smartphones based on previous user
activity and on analyzing habits for construction of passwords of Portuguese people.
4.3.3.4
Interactive multimedia
Given its very nature, Interactive multimedia addresses multiple areas, with direct social impact:
− Health – Work was performed on a Health Kiosk (that automates the collection of vital signs and
other medical data and is able to interact with the patients' health records) and on Voice Coaching
for Reduced Stress (annotating utterances with stress using different methods (experts, heart rate
sensors) and validation).
− Games – Developments on algorithms for 3D virtual environments and MMOGs (massively
multiplayer online games), including reconstruction algorithms, trust computing, and migration
algorithms, and aspect of serious games technologies.
− Human Interfaces – Two aspects were addressed: Augmented Reality with natural user Interfaces
focusing on the natural interaction to allow users to manipulate data and digital systems; and
159
advanced remote control for user interaction with multimedia content. Look-a-Like avatars, for
online cloud base engine, were developed, including aspects on Facial Synthesis within Virtual
Reality.
4.3.3.5
Multimedia signal processing
Many topics have been addressed by the multiple IT research groups in multimedia signal processing.
The research topics are presented with a technical flow order logic, this means starting from analysis
and going through coding, rendering and finally quality assessment.
4.3.3.5.1 Monoview video coding
IT has addressed the:
− Design of a novel HEVC based framework offering quality scalability on top of a HEVC compliant
base layer while appropriately combining the predictive and distributed coding paradigms, a
machine learning based side information creation mechanism and an adaptive correlation
modelling process.
− Design of two novel improved merge mode prediction solutions that adaptively refines the motion
vector candidates in the context of the HEVC scalable extension to achieve the highest
compression efficiency.
− Design of a novel hybrid video coding solution combining pixel and feature based coding tools.
− Assessment of the impact on distributed video coding (DVC) of upgrading the standard Intra
coding component from H.264/AVC to the recent and more efficient HEVC standard to strengthen
the DVC positioning in the video coding landscape.
− Research and development of robust coding techniques to improve the error resilience of the
state of the art video encoder (HEVC) based on dynamic reference picture selection modes. Added
with specific enhancement techniques to mitigate the effect of partial or total loss of individual
descriptions.
− Fast intra coding procedures for HEVC. The intra coding operations defined in the HEVC standard
require a significant amount of computation power during HEVC compatible video encoding.
4.3.3.5.2 Multiview video coding
IT has handled the:
− Design of a novel adaptive interactive multiview video streaming solution where clients select
their preferred viewpoint in a given navigation window based on a layered multiview
160
representation.
− Development of an inter-view SI creation technique for multiview distributed video coding using
SIFT-based homographies relying on a local estimation process.
4.3.3.5.3 Light field image coding and processing
IT has handled the:
− Design of a non-scalable coding solution for light field image and video content, based on
improved intra frame prediction methods that better exploit the inherent structure of this type of
content.
− Design of a scalable coding solution for light field image and video content, in which higher
scalability layers correspond to richer interactivity possibilities for the consumer of the content. An
investigation on depth extraction from light fields was initiated for the purpose of depth-based
light field coding, among others such as surface analysis and modeling.
− Development of interactive tools for rendering light field content, depth extraction and quality
assessment.
New degrees of freedom in terms of 3D light field content processing and coding have been also
explored, such as the investigation of light field depth estimation techniques, light field depth image
based rendering techniques, and geometric-transform based coding. These activities have been carried
out under the scope of the ICT COST Action IC1105 - 3D-ConTourNet and IT project 3D-SERVICIS.
4.3.3.5.4 Holographic and Point cloud coding
Design of a point cloud compression technique that involves partitioning of the point cloud data into
clusters where each cluster can be independently spectral transformed to obtain coefficients for each
vertex of a cluster. IT has also developed a more efficient HEVC based holographic data coding solution
by including optimized transforms for each Intra coding mode; the optimized transforms improve the
capability of the codec to consider directional redundancies.
4.3.3.5.5 Visual rendering
In computer graphics, IT has developed algorithms for the simulation and rendering of weather clouds,
as well as algorithms for ray casting and tracing, and for occlusion culling. It has also developed
geometric algorithms to render molecules with millions of atoms.
IT has developed an Epipolar Plane Image (EPI) based view rendering framework for 3D video coding
representing the cube of views (3D light field) by a cube of EPIs whose compact representation involves
161
disparity estimation based on all the views available, rather than only a few, thus offering a global
approach to synthesis.
Also, IT has developed a light field based 360o panoramas creation algorithms exploiting the potential of
light field cameras.
4.3.3.5.6 Video processing for streaming
Design of a novel decoder quality boosting algorithm based on machine learning where any standard
compliant bitstreams are decoded with better quality in the lower rate/quality periods that succeed to
higher rate/quality periods due to network bandwidth variations.
4.3.3.5.7 Image and video coding/decoding
It performed research on image and video compression techniques beyond the current coding
standards:
− Three-dimensional pattern matching algorithms and the application of geometric transforms in
disparity compensation in 3D video coding.
− Computationally efficient techniques for image compression in many-core platforms.
− Summarisation and key-frame extraction algorithms for 2D/3D video.
4.3.3.5.8 3D Video
Several initiatives on 3D covered:
− 3D Video summarization When a user needs spend less time to view a video clip than its total
runtime it usually resorts to fast-forward viewing mode. This strategy however is not necessarily
the best one as it treats the entire movie as equally relevant. A better solution is to use a
summarization pre-processing stage, to identify the more relevant frames of the video clip
allowing a compliant player to reproduce only those frames marked as belonging to the summary.
The special case of 3D video poses additional challenges related to the importance of depth
information
− 3D Video Quality of Experience Estimation 3D video represented in one of the several accepted
formats (stereo, texture+depth, ,multi view) and transmitted in packet switched networks (after
encoding) is subjected to significant degradations when packet losses occur. The goal of the
research activities currently being carried out under this topic is the modeling and test of final QoE
estimators that are able to predict the final quality of decoded video as perceived by human
observers. A family of low-complexity models based on neural networks and making use of
162
packet-layer only information have been developed which present good performance. A new
model for quality monitoring of 3D video (video-plus-depth format) delivered over hybrid
broadcasting networks was devised. A new perceptually aware quality metric was also successfully
developed and validated.
− Development of error concealment methods specifically targeted for depth maps and efficient
processing techniques for quality enhancing of depth maps generated by RGB-D Sensors. Novel
error concealment methods based on geometric transforms were proposed to recover corrupted
depth maps in 3D multiview video-plus-depth.
− Crowd Evaluation of 3D Video Quality This line of research deals with the development of
procedures and platforms that can be used to collect 3D video quality grades using a distributed
crowd paradigm.
4.3.3.6
Pattern and image analysis
IT has developed research on pattern and image analysis in different fields.
4.3.3.6.1 Image Quality assessment
The area of quality assessment is an increasingly important area in image. IT has addressed the following
techniques in quality assessment:
− Eye gaze behavior under chromatic impairments and quality assessment: Attention maps of
images with induced chromatic errors are obtained with an eye-tracking device. Those attention
maps are analyzed and compared with the MOS obtained from the subjective evaluation of the
considered images.
− Specific Chromatic Errors Quality Assessment: Color change results from the application of a
predefined chromatic error to the chromatic coordinates of all pixels were displayed for subject’s
visualization that were asked to rank their quality based on their naturalness.
− Quality comparison of the HEVC and VP9 encoders performance: A subjective test for assessment
of the Quality of Experience provided by the two codecs was performed.
− Benchmarking of objective quality metrics for HDR image quality assessment: In total, 35 objective
metrics were benchmarked using subjective scores as ground truth. For each metric, objective
scores were fitted to subjective scores using logistic fitting.
− Evaluation of the emerging JPEG XT image compression standard: The question addressed here is
to understand if this model allows extracting a new LDR representation using a different TMO,
independently of the TMO used to generate the LDR image encoded in the base layer.
163
4.3.3.6.2 Speech Processing
The work on the field of robust acoustic modelling has been continued with children's speech models for
reading assessment, as well as measurement of reading proficiency in children. Under the scope of
LetsRead project, that aims to develop a Computer-Assisted Language Learning (CALL) mobile,
interactive, application, for helping Portuguese children in their reading activity at the
primary/elementary school level, a speech database from children (6-10 years old) on private and public
schools
was
created.
Full
annotation
was
accomplished
for
words,
disfluencies
(cut/interrupted/wrong/extra words, filled pauses) and special events, in order to enable research and
development on acoustic and pronunciation models. Furthermore, an automatic speech recognition
module integrated in an automatic sign language interpreter was developed.
4.3.3.6.3 Transportation Systems
IT has designed an analysis algorithm for road pavement surface images targeting the automatic
detection and characterization of cracks. A toolbox (CrackIT) has been made available for researchers
working on the problem of road infrastructures management.
A system was developed for the automatic analysis of video snippets capturing road traffic, available
from the internet, to count the number of vehicles on a given traffic lane, and estimation of road traffic
congestion.
4.3.3.6.4 Medical applications
Medical applications associated with both pattern analysis and image analysis have been widely explored. In
these areas we can identify:
•
Pattern analysis
− Creation of a testbed for the assessment of the circulatory network effects on the development of
cancer.
− Algorithms for biosignal aquisition, processing, and storage, including the acoustic characterization
of the cataract with ultrasound techniques.
− Segmentation method for breast ultrasound masses based on multi-resolution analysis
− Application of texture analysis to muscle MRI:
− Autonomic Nervous System (ANS) Balance. Spectral analysis of autonomic nervous system using
pseudoentropy measures, with time frequency analysis methods (Wavelets and Hilbert-Huang
Transform) applied in Heart Rate Variability and Blood Pressure signals to extract Autonomic
Balance.
164
− Interactive systems for gastroenterology for both training and assisted decision during exams.

− Texture analysis and machine learning used in dermoscopic image processing for melanoma.
− Transfer learning and deep learning to detect breast cancer based on single-cell information
− Gene expression data analysis with observer metaphor.
− Ultrassound image analysis for rheumatology, including bone segmentation and extensor
tendon segmentation
4.3.3.6.5 Biometrics bsed people analysis and recognition
IT has worked on biometric recognition systems and automated surveillance, aiming to obtain an
automaton able to recognize human beings without requiring their participation. Issues addressed
included: design of a view-invariant gait recognition algorithm, focusing on the determination of the
walking direction of a person detected in a video sequence captured in unconstrained conditions;
development of an integrated environment (BioFoV) for supporting the forensic analysis of surveillance
videos, including the computation of soft-biometrics; development of a face recognition solution using
clustering and super-resolution from low quality face images detected in surveillance videos.
Furthermore, IT developed a biometric recognition system for matching partial and degraded (by one of
several degradation types) palmprints obtained from forensic scenarios against palmprints registered in
a database.
4.3.3.6.6 Analysis and description of images and video
Many aspects in image description were addressed:
− Development of software tools, compliant with recommendation ITU-R BT.1702, for the real-time
detection of video content with fast luminance variations, or with spatial patterns of high contrast
(referred to as epileptogenic visual content).
− Design of an algorithm for the detection of video segments without temporal activity and their
classification as still images transmission, black frames, segments naturally without motion, and
segments with repeated frames due to transmission losses or delays (video stalls).
165
− Design of an algorithm to identify video segments containing violence, using features extracted
from the video and audio signals as well as from the subtitles text.
− Design of a novel binary feature coding solution using distributed source coding principles where
the features are extracted at the sensing nodes which are transmitted to enable visual analysis at
some central location
− Design of a novel multi-view distributed feature selection technique where the efficiency of the
visual analysis is improved by employing several neighboring cameras which sense partially
overlapped areas.
− Design of a novel visual tracker that performs descriptor matching between consecutive frames,
applies filtering techniques to remove undesirable outliers and employs a suitable model to
characterize the object appearance; in addition, techniques to code and transmit these
description streams are employed.
− Design of binary descriptor coding methods and a novel tracking-by-detection framework to
perform visual tracking in a stereo-based analyze-then-compress system where features extracted
from different cameras are used to characterize the object appearance with a suitable model.
4.3.3.7
Architectures, protocols and services
IT has addressed multiple areas inside the field of architectures, protocols and services. Mobile network
aspects will be addressed in the following section.
4.3.3.7.1 Multimedia and QoS-Aware Networking
In terms of multimedia-related networking, IT developed a global OTT architecture, with content
prediction, distributed caching and information delivery. This Content distribution network in over-thetop networks includes a feature of Automated Recording and OTT Publicity, and a complete a complete
analysis of catchup-TV pattern consumption.
Furthermore, IT has developed dynamic and adaptive resource reservation mechanisms for large
distributed embedded systems. In particular we developed a mechanism to scale the FTT-SE protocol
(Flexible Time-Triggered Switched Ethernet) as a central piece in a resource management framework. An
architecture based on HaRTES (FTT-enabled) switches was also explored (see hardware realizations).
Moreover, we continued the work towards network management with hierarchical traffic scheduling to
provide hierarchies of virtual channels with mutual temporal isolation.
166
In a different line, IT developed a reliable streaming multicast protocol (and demonstrator) that scales to
large number of clients using feedback-based Network Coding with judicious scheduling of clients
feedback.
4.3.3.7.2 Information-Centric Networking
Research in the area of ICN is a strong commitment of IT, with particular focus in flexible coordination of
the network infrastructure, in the light of future networks and existing telecom driven cellular networks.
This effort resulted in active participation in the Information Centric Networking Research Group
(ICNRG) of the IRTF, resulting in drafts and the authorship of RFC 7476.
4.3.3.7.3 Software Defined Networking
Networks are embracing the flexibility provided by software agents, and exploring novel use cases and
services, which are enabled by the standardization efforts related to the OpenFlow protocol. The IT has
applied OpenFlow to the realization of advanced mobility management solutions. In particular, it has
built upon its long experience with fast mobility for cellular and wireless scenarios, developing solutions
for end-to-end mobility, and edge node mobility control based on the novel SDN concepts and through
OpenFlow. IT has also developed a Open-Flow based network management approach, and mechanisms
and algorithms for fault-management and reconfiguration of network and cloud resources through SDN.
4.3.3.7.4 Network Function Virtualization
Telecom providers are exploring the opportunities presented by SDN, and with particular interest the
possibility of increased flexibility and decreased cost by virtualizing some of the network equipment. IT
has worked closely with research partners, and telecom providers in the development of actual
solutions for the virtualization of several components. This has led to the recognition of IT as an Official
OpenStack Supporting Company, with the addition of IT to the OpenStack webpage.
4.3.3.8
Mobile Networks
Mobile networks are one of the most active and diverse area in telecommunications. IT naturally is
strongly involved in this area.
4.3.3.8.1 Vehicular Networks
The commitment to vehicular networks has been well established for long. In the last year, work was
performed in: integration of mobility mechanism with multihoming for the connection of vehicles to
several networks simultaneously, as well as predictive mechanisms for selecting best connections;
development of local services for Road Side Units; security aspects for vehicular networks; opportunistic
167
routing for vehicular networking; storage strategies using Helix emulator; dissemination strategies;
protocols for Vehicular Delay Tolerant Networks; and integration of sensors in board unites of the
vehicular network. The 600 vehicle network in Porto has been constantly running performance
experiments and integrating new mechanisms; some of these mechanisms were also tested in the
experimental network in the harbor of Leixões.
4.3.3.8.2 Mobile Ad-hoc Networks
Closely associated with Vehicular Networks, nevertheless there were several works on mobile ad-hoc
networks which had a wider application. IT has been involved in delay tolerant communications for navy
scenarios, and for aquatic drones. Routing protocols for DTN (Q-Prophet), exploring the different quality
of links, and with improvements for measuring the link quality in an integrated way, were some of the
areas developed.
4.3.3.8.3 Mobility in Telecommunications Networks
Besides the vehicular networking, IT has developed work on high performance mobility, and continues
to advance this area by contributing with novel mobility management solutions. These solutions are
thoroughly tested and mature, being able to provide effective mobility management mechanisms in a
generalized form for most IEEE 802 based networks, as well as some 3GPP aligned cellular networks. IT
has developed distributed mobility mechanisms in flat networks, and optimized traffic allocation in
different technologies and networks
4.3.3.8.4 IoT, M2M and Smart Cities
The internet is including devices in its fabric, creating an Internet of Things, and then an Internet of
Everything. This trend is being specially felt on the concept of Smart Cities. IT has contributed to
advanced scenarios and technologies by working on the design of management platforms, incorporating
concepts related to security and high availability, with the integration of novel use cases and
management interfaces, through custom solutions and conceptual designs.
Some specific initiatives are worth explicit mention
− Future Cities project - Porto Living Lab. Multiple areas were covered in this project: Data collection
campaigns (Scope (policemen), MoodSensor (city-wide hapiness), FEUP mobility), APIs, device

− Environment and Agriculture – Activities covering modernization and innovation based on ICT in
agri-food companies of central region of Portugal have been trialed, as well as intelligent control
systems for variable volumetric water reservoirs. The objective was to develop a novel
technological solution to control energy consumption in an efficient way to minimize impacts on
the environment.
4.3.3.8.5 5G and Future Internet
The internet is in a clear revolution as new usage models appear and the efforts around 5G take place. IT
is following the developments related to future architectures and solutions by participating in important
associations, think tanks and consortia. In particular, an IT researcher is member of the 5G-PPP steering
board, the most important 5G related European association. Also, IT is member of the CONFIG (COntrol
Networks in FIve G) consortium which aims to develop an effective architecture for future 5G networks.
4.3.3.8.6 Networks and Services for Mobile Teams
Two major areas were addressed:
− Communications for teams of collaborating mobile autonomous robots. We developed a method
that allows obtaining position confidence levels based on the uncertainties of the pair-wise
distances. We also explored routing within TDMA multi-hop networks and we developed a new
protocol that strongly reduces the variations of end-to-end latencies and isolates the traffic flows
generated by different sources providing network-wide composability in the time domain.
− Vital Responder 2 project. Development of a prototype for ECG data collection over a wireless
MANET of smartphones. Mobile MANET prototype on RPi. Experimental performance evaluation:
energy consumption, communication range, network connectivity and throughput. Protocol for

4.3.3.9
Information Technologies
Two major areas have been addressed in terms of Information Technologies: Big Data and Knowledge
Development and Sharing.
4.3.3.9.1 Big Data Social Analysis
The amounts of data currently available rapidly enables novel use cases for exploiting services and
devices, considering that its volumes are able to be processed and it presents a clear structure. Work
was performed in both areas related to the extraction of structure from unstructured (IoT) data, and the
analysis of large data sets to provide clues enhancing existing services. This has led to several
contributions as well as novel methods for real time processing of large amounts of unstructured textual
information, knowledge extraction and the creation of clues for enhancing multimedia services.
4.3.3.9.2 Knowledge Development and Sharing
Several artificial intelligence techniques were explored, and novel techniques were developed in these
fields: agent architectures; Hierarchical Reinforcement Learning; Dynamic Scheduling; and Time
Sequence clustering and prediction. Areas where these techniques were explored was on robot control
in multi-robot systems, and on the treatment and tracking of Alzheimer’s disease.
4.3.3.10 Hardware Realizations
The Networks and Multimedia line have developed several activities coupled with physical realizations
of some concepts, due to the challenging realization requirements of such concepts. Two major lines
have been tackled: parallel realizations and embedded devices.
4.3.3.10.1 Parallel Computing
Significate amount of work was performed for the development of parallel kernels and data structures
for accelerating compute-intensive signal processing algorithms under the context of error correcting
codes used in data communications, in the area of medical imaging for diagnosis support, 3D
reconstruction from stereo pairs and in the study of electron wave propagation on graphene.
Mobile GPUs, low power FPGAs (reconfigurable hardware), GPU were tools used for multiple
applications: Stacked Autoencoder Neural Networks; real-time 3D reconstruction; parallel kernels based
on 2D stereo inputs; non-binary LDPC decoders, with mitigation techniques and analysis; medical
imaging and signal processing acceleration (ultrasound, blood analysis, etc…). Both OpenCL and CUDA
have been used in these developments.
170
4.3.3.10.2 Embeded Systems
Many networked embedded systems have real-time constraints and are safety critical. Thus it is require
to handle implementation of standards-based dependable real-time communications for safety-critical
systems, both wired (e.g. CAN and Ethernet) and wireless (e.g. IEEE 802.11, IEEE 802.15.4).
Fault tolerance techniques for both wireless and wireline networks have been developed, exploring
dynamic scheduling features of the VFTT protocol (in the wireline) and architectures for allowing
coordination among overlapping base stations (in the wireless). This was enriched by developing
HaRTES, a real-time Ethernet architecture that conciliates flexibility with real-time requirements, and
with support with MAC Bridge standard functionalities, to make it capable of being integrated on
Industrial Internet of Things frameworks.
In order to support heterogeneous applications with demanding communication requirements and
provide efficient application development processes, it was developed a framework integrating
6LoWPAN protocols and services on a real-time operating system (Contiki OS) for low-end
microcontrollers.
IT has also developed a prototype board that supports multiple sensors and Bluetooth LE to send
biodata to a smart phone, including an onboard oximeter with red and infrared LEDs to boost the light
intensity and improve the measurement accuracy under normal daily life conditions. The experimental
nature of this oximeter, imposes the use of custom data profile for Bluetooth LE communication and
requires a custom application for processing the data.

VERE: Virtual Embodiment and Re-Embodiment
Funding
EU/FP7
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
172
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.

3D Video Quality Monitor
Funding
IT/LA
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.

Title
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
173
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
distributed coding approach provides a significant architectural benefit since it does not
require any 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-ofthe-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 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 errorprone networks (typically wireless).

Integrating Biometrics and Forensics for the Digital Age
Funding
ESF/COST
Descript.
“Forensics is the application of a broad spectrum of sciences to answer questions of
interest to a legal system. This may be in relation to a crime or a civil action” [Wikipedia].
Since many such questions boil down to identifying, or verifying the identity, of people
175
allegedly involved in some action, a clear relationship exists between forensics and
biometrics. Biometrics developed a number of techniques which can clearly facilitate the
identification of people involved in criminal actions or civil incidents. Thus, although the
two communities have traditionally often operated in relative isolation, there are many
scenarios where the synergic cooperation of multimodal biometrics and forensics can be
successfully applied. To address such multifaceted areas it is important to develop an
interdisciplinary network with complementary competences, to foster the birth of a new
community which can develop novel technological solutions to crucial issues and new
challenges in forensic science. The Action will promote new partnerships, will provide
education and training, will contribute to develop new standards and best practices, will
produce awareness of the potential benefits of advanced technologies for evidence
analysis in forensic cases and will stimulate improved mutual understanding of
collaborative working models linking the academic and industrial sectors.

Networked energy-aware visual analysis

Descript.
The potential of the Internet of Things is leading to a paradigm shift with an ambitious
long-term vision, in which battery-operated sensing nodes are empowered with sight
and are capable of complex visual analysis tasks. Unfortunately, this is out of reach with
the current technology. GreenEyes will develop a comprehensive set of new
methodologies, algorithms and protocols, to empower wireless sensor networks with
vision capabilities comparable to those achievable by power-eager smart camera
systems. The key tenet is that most visual analysis tasks can be carried out based on a
succinct representation of the image, which entails both global and local features, while
it disregards the underlying pixel-level representation. Still, under severe energy
constraints it is imperative to optimize the computation, the coding and the transmission
of the features. On the computation and coding side, GreenEyes will tackle the problem
by reversing the conventional compress-then-analyze paradigm. That is, image features
are collected by sensing nodes, processed, and delivered to final destination(s) in order
to enable higher level visual analysis tasks by means of either centralized or distributed
177
detectors and classifiers, somewhat mimicking the processing of visual stimuli in the
early visual system. The transmission of visual features is subject to tight applicationdependent requirements (bandwidth/delay guarantees), and may be affected by
network conditions. Therefore, on the communication side, GreenEyes will pursue the
design of networking tools for wireless multimedia sensor networks for energy efficient
distributed control, information delivery and in-network processing optimized for the
visual analysis task.

Social networks have become an integral part of the digital life of nowadays society.
Indeed, the preponderance of these networks has increased significantly in the last
years, allowing users to share different types of multimedia contents with the
community [FB, FK, YT, TW, LN, Ala08]. In the last years, we have also assisted to a
dramatic increase on the number of attacks on these networks in order to obtain and
access confidential data from several users. In this manner, it is possible to create and
178
execute powerful targeted social network attacks which, by exploiting the information
shared on such networks, can become more credible and difficult to detect. Indeed,
according to a recent report, the number of phishing attacks over social networks has
increased more than 1200% during 2010 [Microsoft11]. The project Social Network User
Behavior Modeling aims at analyzing and modeling the behaviors of social networks
users in order to create behavior models. With such models, the project aims at
increasing the knowledge the users have of their connections and of the social network
in general, creating a trust relationship between the user and the remaining community.
These models will also allow the detection of profile changes, or behavior models, in
order to detect compromised accounts or accounts created by hackers with the purpose
of accessing informations other users may share over the mentioned networks. The
creation of such models enables the social network to map each user to group, allowing
a more efficient, direct and secure management of existing groups of users as well as the
creation of novel groups. Novel recommendation systems can also be proposed. All the
mentioned aspects illustrate the importance of this project.

DEVELOPMENT OF NEW METHODOLOGIES BASED ON ULTRASOUND TECHNIQUES FOR
IN VIVO CATARACT CHARACTERIZATION
Funding
FCT/PTDC
Descript.
Cataract is a clouding or opacity that develops in the crystalline lens of the eye. For
clinical prognostic and therapeutic purposes it is very important to identify the cataract
type and the disease stages especially in its early stages (Paunk 2007). With increasing
relevancy, the ultrasounds appear as powerful, noninvasive and less expensive
technique for tissue evaluation. Concerning to cataract treatment, phacoemulsification is
the most common surgical procedure by using a hand-held ultrasonic device to fragment
the clouded lens into small pieces that are then aspirated (Wilson 2005). To emulsify the
cataract, the selection of the optimal ultrasound energy level is of fundamental
importance to prevent the endothelial cells damage and the posterior capsule rupture.
This unrecovered injury can be avoided if the hardness of the cataractous lens is
previously and correctly estimated. The applicability of the ultrasound methods for
characterizing both normal and cataractous lenses has been studied for decades. Two
important ultrasound parameters, velocity and frequency- dependent attenuation have
been used trying to evaluate the hardness of the cataractous lens in porcine and human
eye tissue. The most important one is related to the fact the results only provide
information about the cataract presence and respective hardness globally, because
evaluation is made considering the anterior and posterior reflected lens signals. Thus,
important information as the exact regional hardness of cataract is not achieved with
this methodology. Also, there is no adequate noninvasive characterization of regional
location and hardness of cataract. This is of particular importance for estimating the
optimal phacoemulsification energy, which should be adjusted for the different hardness
levels that can be found in all extension of cataract. In this project it is intended to use
the backscattering signals, instead of the anterior and posterior lens echo signals
frequently used in literature, to extract features capable to characterize the mechanical
properties of tissues, namely scatter density and mean scatter size for subsequent
correlation with the lens hardness. Time and frequency domain features will be
evaluated in order to identify the most powerful ones. Several feature classifiers such as
Artificial Neural Networks, Support Vector Machines, k-Nearest neighbors, and Naive
Bayes will be tested and their potential evaluated for quantification of regional changing
of cataract hardness. To develop a medical device for cataract surgery and clinicians
181
support to access cataract hardness and location for any type of cataract, and determine
in real-time the optimal energy for phacoemulsification, pre-clinical studies will be
performed in vitro, in porcine lens, and in vivo in rats animal models that simulate
different types of cataract. The animal models will allow the translation from pre-clinical
to clinical research.

Our main goal is to design signals with low Peak-to-Average Power Ratio (PAPR) or even
quasi-constant envelope and high spectral efficiency, employing amplification
techniques based on low- cost, highly efficient grossly NonLinear (NL) amplifiers (e.g.,
class D and E amplifiers), which are simpler and have higher amplification and output
184
power then quasi-linear amplifiers. Since a grossly NL amplifier is only suitable for signals
with quasi-constant envelope, we will develop new signal designs and/or transmission
techniques compatible with grossly NL amplifiers. This research project combines
theoretical development (including signal and receiver design), CMOS implementation of
key components (with emphasis on matched amplifiers and output power combination
with minimum losses) and FPGA-based implementation for an overall system’s proof of
concept, for the most promising techniques.

Heterogeneous Ad-hoc Network for the Coordination of Aquatic Drones
Funding
IT/LA
Descript.
The goals of this project are to design, implement, and evaluate a heterogeneous
network architecture for aquatic drones, and to demonstrate the feasibility of collectives
of low-cost aquatic drones for maritime tasks such as environmental monitoring, sea life
localization, and sea border patrolling. Common to such tasks is that they require
collectives composed of large numbers of drones. The feasibility of a system for such
tasks therefore depends on the unit cost (which should be kept as low as possible), and
on the capacity of the network architecture and control logic to scale. As the number of
units increases, unit failure will become more frequent and fault tolerance must
therefore be built into both the network architecture and the control logic. The specific
challenges to be addressed in the HANCAD project are:
• Development of a scalable, heterogeneous, and fault-tolerant ad-hoc network
architecture for aquatic drones
• Synthesis of decentralized control logic to maintain network connectivity during task
execution
• Implementation and demonstration of a collective of 10 low-cost aquatic drones
performing proof-of-concept tasks.

Smart Diabetes Self-Management Care
Funding
FCT
Descript.
Diabetes is a rising disease in terms of number of people affected and the costs
associated with its treatment. 439 million adults and USD490 billion are estimated by
2030. Portugal had, in 2011, 12.7% of the population between 20 and 79 with the
disease. This project aims to develop a smartphone application to help the diabetic
patient deal with managing the disease. A first step is to enable data recordings of the
daily diabetic life in an intuitive and simple way, so not to be a burden, which can
undermine the gathering of the information. This information taking should be seen
more as a process (e.g.: having a meal implies registering carbohydrates, glycaemia,
insulin) than a direct and separate register of several records. A second step is to
incorporate the knowledge/protocols of doctors and nurses into the application. These
protocols allow to react to certain patterns of behaviour, detected by the records taken.
As an example, it could warn the user that it made exercise 2h ago and that perhaps her
insulin dose should be adjusted, or that the current illness situation (that has been going
on for 2 days) would merit an insulin correction. A third phase would be the pattern
analysis of the data gathered, to search for patterns in two ways. One would be to
provide feedback for the patient regarding some behaviour/actions that may be inducing
erratic or bad disease control, e.g. detection of recurring low values before bedtime
occurring when high values of carbohydrates where consumed at dinner time. The other
perspective, would be for a more global analysis using the aggregated data from several
patients for medical purposes. Here insights on insulin adjustments, differences between
patients using same approaches, unknown correlations could be analysed from an
endocrinologist point of view with more data to support it.

In this project, we aim to develop new spatiotemporal prediction tools, as an alternative
to the traditional frame-by-frame intra and inter prediction techniques. Since motion
estimation is one of most computationally demanding tasks on hybrid video codecs, the
alternative spatiotemporal techniques can give an important contribute while
developing low complexity/high performance video codecs. Particularly, it was
demonstrated that not only the Least-squares prediction can achieve competitive results
when compared to the traditional motion estimation, but also that there exists a strong
correlation between edges in space and object trajectories in the time domain. Based on
these observations, we believe that both the spatial and temporal redundancy can be
exploited with similar approaches, namely using three- dimensional coding units.

o Subjective test, and hence MOS values and other statistic properties will be used to
evaluate the video quality when subjected to different impairments. o Using the
detection of points of interest to study the local influence of perturbation on QoE
assessment. - With the MOS assessment and the visual attention results, different
factors that have influence in the QoE evaluation will be identified. - The influence of
the different factors will be quantified using appropriate features in a multidimensional

evaluate QoE. - To study and develop QoE models for QoE evaluation of video
applications that can present a better correlation than the existing in the literature
(which in the current state do not present acceptable correlation to be used in real

Beyond Convexity: Non-Convex Optimization and Game-Theoretic Approaches for
Imaging Inverse Problems
188
Funding
FCT
Descript.
Imaging inverse problems (IIPs) abound in the modern world. Medical imaging (CT, MRI,
PET, ultrasound), remote sensing, seismography, non-destructive inspection, digital
photography, astronomy, all involve at their computational core the solution of IIPs: they
produce visual representations (images) of an underlying reality from indirect/imperfect
observations. In a nutshell, the goal of this project is to advance the state of the art in
computational methods for IIPs, by exploiting the promising new possibilities that lie
outside of the classical convex optimization approaches. IIPs are ill-posed: even if the
observation operator is perfectly known, the observations do not uniquely and stably
determine the solution. This difficulty is dealt with by seeking a compromise between
data fidelity (fitting the observed data) and adherence to properties that the unknown
image is known/desired to have. The classical way to seek this balance is to formulate an
optimization problem (usually convex, more by reasons of mathematical tractability than
model adequacy), where the objective function includes a term encouraging data fidelity
and another (the regularizer/prior) penalizing undesirable solutions; in this approach,
convex optimization takes center stage and has been in the limelight of computational
imaging. If the observation operator is only partially known (in the so-called blind
problems), the goal is to infer, not only the underlying image, but also the missing
information about the observation model. Blind problems are obviously more ill-posed,
requiring regularizers/priors that better model the images of interest. Moreover,
variational formulations of blind IIPs are naturally non-convex, thus out of reach for the
efficient convex optimization tools developed in the past decade for the convex
formulations of non-blind IIPs. Consequently, the methods that have been proposed for
blind problems lack convergence guarantees and require "tricks" in order to work well
(e.g., careful initialization and continuation procedures), making it hard to trace their
(non)success to the behavior of the optimization algorithm or the (in)adequacy of the
objective function. Non-convexity also stems from using non-convex regularizers, even
in non-blind IIPs, e.g., constraints/penalties on the number of coefficients that represent
the image on some frame or dictionary. These non-convex regularizers are central in the
recent theory of compressive sensing and much research has been devoted to finding
conditions under which similar solutions are obtained with convex relaxations. Very
recently, algorithms that directly tackle the non-convex formulations have been
proposed by exploiting particular properties of the observation operator, namely their
restricted isometry properties (RIP). However, in IIPs, the RIP is essentially impossible to
guarantee, making the application of these non-convex approaches an open research
front. This project aims at advancing the state of the art in computational methods for
IIPs, by departing from the convex optimization realm and its limitations, in several
directions: a) We will investigate optimization methods for non-convex formulations of
blind IIPs; unlike previous approaches, we seek methods with theoretical guarantees and
without careful user interaction. Of course, non-convex optimization can only be
approached by exploiting specific characteristics of the class of problem in hand; this is
189
precisely the strategy we will follow. In particular, a recently proposed new class of
algorithms for non-convex structured functions, based on the Kurdyka-Lojasiewicz
property, is a promising tool for this quest. b) We will develop algorithms for nonconvex regularization, by exploiting the lines of attack that have recently been
successfully followed for compressed sensing (CS). However, unlike in CS, the
observation operators in general IIPs do not exhibit RIP, thus other characterizations are
needed to support the sought for theoretical guarantees. c) For blind IIPs, we will seek
formulations of the compromise between data fitness and regularization as equilibrium
(rather than optimization) problems, namely via variational inequalities (VIs) and game
theory. Since optimization problems are particular cases of VIs but the reciprocal is not
true, this approach contains and extends the standard optimization formulation, opening
the door to more general criteria and computational methods. For example, blind
deblurring can be formulated as an equilibrium problem (a game) between estimating
the underlying image and estimating the blur.

Bike sharing systems have been very successful in many cities worldwide. In Aveiro,
Portugal, the BUGA system was pioneer, but it has never evolved to an automated
operation mode. The first automated bike sharing system in Portugal, was deployed in
Vilamoura in 2011/12. There are some relevant examples of popular and effective bike
sharing system in Europe, notably in London, Paris, Barcelona, Madrid and Hamburg.
Current automated bike sharing systems require docking stations to park the bicycles, to
interface with the user and to connect them to the backhauling information system. The
193
evolution of these systems was mostly concentrated on the information systems,
improving the usability, the access (mobile phone and web) and the payment process.
We are witnessing a growing dissemination of electric bicycles. These bicycles behave
like conventional bicycles, as they can be used without electrical motor support, or as
semi-assisted electrical bikes (“pedelecs”), since the driver has to move the pedals. With
electrical motor support, the autonomy is around 100km without significant driver
physical effort, except the need to move the pedals. It is expected that this technology
will multiply by 5 (from 6% today to 30%) the number of potential users of bike shared
systems, encompassing people moving for work, people aged over 60 and people with
poor physical shape unable to ride a standard bicycle for medium size journeys. The
recently concluded bikeemotion® project, integrating Ponto.C, Ubiwhere, Micro I/O and
the University of Aveiro, has developed a prototype fourth generation (station less) bike
sharing system adaptable to any bicycle, in which the bicycle includes not only the
locking system, but also GPS and mobile communications. In July 2013 the bikeemotion®
prototype was awarded the “Urban Planning and Urban Design – Cycling Visionaries

Bikeemotion project continues the work of the bikeemotion® project to develop the fifth
generation of bike sharing systems, accommodating the use of electric bicycles and the
consequent broadening of the range of users. The R&D activities of the project include
the following lines of work:
• Embedding of sensors in the bicycle and in the driver to monitor biological signals, e.g.
ECG, blood pressure, skin conductivity, etc.
• Close the control loop between the bio-sensors and the electrical motor.
• Extend the communication capabilities of the bikeemotion® architecture.
• Energy harvesting and smart battery charging.
• Cloud-based information system to manage the bike-sharing system

NET-PORT: Soluções de Comunicações entre Veículos para Portos de Mar e Aeroportos
Funding
Veniam
Descript.
O objetivo principal do projeto NET-PORT será a conceção e desenvolvimento de novas
soluções e serviços de rede, de elevado valor acrescentado, na área de sistemas de
comunicação entre veículos para transportes e logística inteligente dentro de portos e
aeroportos. Estas soluções e serviços vão ser suportados por uma infra-estrutura de rede
sem fios de baixo custo de instalação e manutenção, assente em comunicações veículoa-veículo e veículo-a-infraestrutura que utilizam a norma IEEE 802.11p. Através da
integração fiável e segura dos sistemas desenvolvidos com as redes internas e os
sistemas de informação das autoridades que controlam e empresas que exploram portos
e aeroportos, assim como com plataformas do tipo Cloud, o projeto NET-PORT permitirá
à empresa VENIAM diferenciar a sua oferta para sistemas de controlo e gestão
inteligentes em portos e aeroportos, oferecendo soluções chave na mão que introduzam
melhorias significativas na segurança, eficiência, produtividade e impacto ambiental das
operações de controlo e gestão em portos e aeroportos, potenciando assim o aumento
da competitividade da empresa VENIAM, numa ótica de forte internacionalização. Como
principais benefícios para as autoridades que controlam e empresas que exploram
portos e aeroportos, o projeto NET-PORT vai desenvolver uma infra-estrutura de rede
veicular de baixo custo, que possibilitará o aumento da qualidade e a redução dos custos
de transmissão dos fluxos de informação e acesso à Internet por parte de todos os
intervenientes nas operações a efetuar em portos e aeroportos. Além disso, a infraestrutura de rede desenvolvida vai potenciar a aquisição, em tempo real, de uma grande
quantidade de informação de dados sobre as operações e movimentações de veículos,
pessoas e mercadorias nestes meios. O objectivo deste trabalho é permitir a ligação
simultânea a várias tecnologias e redes, para permitir a ligação de um veículo a vários
veículos ou a várias estações em simultâneo, podendo distribuir vários serviços por
várias ligações. Este trabalho permitirá distribuir o tráfego de veículos (por exemplo,
autocarros) por várias ligações simultâneas, para melhorar a transferência de
informação.

4.4.3.2 Scope and Objectives
Basic Sciences and Enabling Technologies (BS&ET) is a multidisciplinary research line providing
transversal background support to IT activities and mission. Most of the work in this line was related to
electronics and optoelectronics. This applies to the activities in Applied Electromagnetics (AE),
Integrated Circuits (IC), Power Systems (PS), Organic Electronics (OE), Power Electronics (PE) and
265
Instrumentation and Measurements (IM). The activities in Applied Mathematics (AM) supported
research performed in other areas, developing tools relevant to telecommunications, and applications
to Simulation, Mathematical Modelling and Systems Stability. Physics of Information was focused on
quantum information theory, quantum effects in biological systems and energy transport, and
nanoenergetics and quantum effects.
4.4.3.3
Expertise and Research Topics
4.4.3.3.1 Applied Electromagnetics
The activities carried out by the group Applied Electromagnetics in 2015 were focused in the broad
domain of Electromagnetic Field Theory and its applications to electric, magnetic, and optical devices,
encompassing three major subareas: Transmission-line structures; Electric and magnetic field problems;
and Computational electromagnetics.
•
Transmission-line structures
-
Hybrid multiwire transmission lines (HMTL) are novel transmission structures where magnetic
transmission lines and standard electric transmission lines coexist and interact. The general
matrix theory of HMTL was developed and later applied to a particular four-wire system, from
where the coupling properties and the wave propagation features of the multiwire structure
were obtained.
-
Overhead power lines were characterized, modelled, and their behavior simulated taking into
account proximity and skin effects, longitudinal variations of the earth surface profile, and
transverse earth stratification.
-
The propagation parameters of medium frequency transmission-line communication systems in
circular cylindrical mine tunnels were evaluated using an exact method based on radial and
azimuthal expansions of the magnetic vector potential. Results were compared with those
obtained using Dubanton’s and Wait’s approximations.
•
Electric and magnetic field problems
-
Shielding techniques for magnetic field mitigation in power transmission lines were proposed
and analyzed.
-
Magnetic field (3D) in the air gap of a ferromagnetic core with superconducting blocks, and
266
magnetic field in a spherical electrical machine, were modelled and analyzed.
•
Computational electromagnetics
The development of computational methods and software tools for electromagnetic field calculation is
key for most of the reported research activities, namely, the development of hybrid methods using both
analytical and numerical formulations (finite element, and boundary element methods). During 2015,
the topic of electromagnetic propagation in bent and ring slab waveguides, and the topic of magnetic
field evaluation in air gaps of ferromagnetic cores, and in spherical electrical machines, received special
attention.
4.4.3.3.2 Applied Mathematics
The research on Applied Mathematics has been focused on Optimization and Numerical Linear Algebra,
Logic and Computation and Criptography and quantum information.
•
Optimization and Numerical Linear Algebra
-
Numerical Linear Algebra: Preconditioning and convergence of iterative methods for the solution
of linear systems of equations, generalized inverses and its applications.
-
Complementarity Problems: design, convergence analyses, implementation and testing of
interior-point algorithms, active-set methods, sequential quadratic algorithms and enumerative
methods.
-
Global Optimization: complementarity algorithms, positive semi-definite and reformulationlinearization techniques for bilevel programming, quadratic and bilinear programming,
eigenvalue complementarity problems and mathematical programs with complementarity
constraints.
-
Solution of structured optimization models arising in telecommunications, civil engineering, and
finance.
-
Optical core networks - efficient ILP models and heuristic solutions for (i) the network design
problem with fixed-grid and flexible grid setups and (ii) for the impairment aware routing
problem.
-
Lightpath admission control algorithms for optical networks based on integer linear
programming methods and performance evaluation based on simulations.
-
Hybrid approaches based on column generation and local search heuristics, for energy efficient
267
routing in telecommunications networks.
-
Routing algorithms for 6LoWPAN mesh networks.
-
ILP efficient models for (i) wireless mesh network design with node degree constraints, (ii) the
single PON network design with unconstrained splitting stages and (iii) the optimal layout of
wind farms for electrical power generation.
•
Logic and Computation
-
Combination of logics: substantial advances in the understanding of fibred logics was achieved,
obtaining full characterizations of conservativity and decidability preservation results in the
disjoint case, and several partial results in the general case, namely using appropriate notions of
translation
-
Compositional meaning in logic: we have explored suitable generalized notions of compositional
meaning in logic, namely in the context of non-deterministic logical matrices, and obtained
several new characterization
-
Computation with real numbers and complexity: we have shown that the physical measure
associated to the (geometric) Lorenz attractor is computable. We have shown how
computational complexity can be properly defined over analog models of computation like
Shannon's General Purpose Analog Computer (GPAC. We have shown that a function is
polynomial-time computable with a GPAC if and only if it can be computed in polynomial-time
with Turing-based computation models.
•
Criptography and quantum information
-
Bit-string oblivious transfer: we developed a quantum computationally secure protocol for bitstring oblivious transfer between two parties, under the assumption of quantum hardness of
state distinguishability and the constraint of performing at most few-qubit measurements
(leaving open the question of general attacks performed on all qubits involved). Our protocol is
feasible, in the sense that it is implementable in polynomial time.
-
Blind signatures and PK: we propose a quantum blind signature which is perfectly secure under
the assumption of a honest offline repository of quantum information. We also proposed a
quantum public key cryptosystem.
Quantum multiparty dense coding: we proposed a quantum multiparty dense coding protocol that
allows the sharing of information among several quantum agents.

4.4.3.3.3 Instrumentation and Measurement
The Instrumentation and Measurement Group works in the broad domain of Metrology. In 2015, the
activity of the Group can be included in the following main topics:
- Non-destructive testing;
- Sensors and transducers;
- Signal acquisition and automated and telemetric measuring systems;
- Signal processing applied to sensors and instrumentation.
•
Non-destructive testing
-
During the past year inspection has been carried out using the linear motion system acquired
in 2013 for the Instrumentation and Measurement Laboratory. The non-destructive method
used is based on motion induced eddy currents. Tests were performed to conclude about the
defect depth in a conductive plate and the sensitivity of the method with velocity in aluminium
materials. Studies are being made to apply the method to steel rails.
-
The cooperation initiated last year with Universidade Federal do Rio de Janeiro will continue.
The objective is the development of a NDT testing system to detect cracks and modifications on
the paramagnetic properties of the wall tubes of reformer furnaces. Some samples of
deteriorated tubes have been received at the laboratory. Two remote field eddy current probes
were built to compare detection and characterization capabilities in standard defects like
longitudinal and transverse defects. Tests initialize now.
-
Work on the inversion problem algorithm applied in eddy current inspection using a sinusoidal
magnetic field with fixed-amplitude is going on. A new probe with two coils able to produce
orthogonal uniform magnetic fields in two wide areas in the sample to be inspected was built.
Two tiny giant magnetoresistance sensors (GMR) with high sensitivity are used to measure the
amplitude and phase of the magnetic field in the sample’s surface. A perturbation occurs in the
measured magnetic field in the proximity of a crack defect. The current density is then
determined around crack defect through an inversion problem algorithm.
-
A new non-destructive testing (NDT) method called transient eddy current oscillations (TECO)
was developed and implemented to detect a change in the thickness of stainless steel covered
with insulation. This method uses a probe built at the laboratory which consists of a capacitor
269
and an induction coil (excitation coil) discharging in a free oscillation mode, while the resultant
magnetic field is detected by using a Hall-effect sensor. Different features were extracted from
the response voltage to detect the thickness of the test specimen and separation of lift-off.
-
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 these sensors and to surpass the limitations of
the traditional NDT methods.
•

Comparison of spin valve and magnetic tunnel junction magneto resistive sensors in eddy
current testing probes.
-

4.4.3.3.4 Integrated Circuits
•
Devices and materials for integrated circuit design
-
SAW Sensing Technology: Most of the work has been aligned with the running project
RTMGear (FP7/Cleansky) targeting the usage of SAW temperature and strain sensors for the
271
instrumentation of commercial airplane gearboxes. The work on this project targeted the
validation of the technology and search for methods to improve sensing accuracy. Two project
proposals were submitted: PHoEBuS (H2020/FET-OPEN) and HEALTHSens (Interreg/SUDOE);
targeting applications of SAW and sensor technologies to the detection of bacteria and
pathogens in food distribution chains and hospitals. The initial efforts were done to build a
collaborative network with Portuguese industry around SAW sensing devices and technology.
-
Memristive Devices: Participation on the Management Committee of the IC1401 COST action
MEMOCis, targeting developments on memristive devices and technologies. Work on this line
of research has concentrated on device modeling strategies and theoretical description based
on Lagrangian and Hamiltonian theories for electric circuits.
-
Hybrid diamond Semicondutor devices: Development of hybrid diamond / wide band gap
semiconductor (GaN, SiC) components for high power / high temperature environments. The
ultimate goal is deposition of diamond films on the surface of final devices (diodes, transistors)

4.4.3.3.6 Physics of Information
•
Physics of Information is a recent research area at Instituto de Telecomunicações, aiming at
promoting research and advanced training in the role of thermodynamics, quantum physics and
relativity in information encoding, transmission and processing. In particular, during 2015,
theoretical research was developed on quantum information theory, nanoenergetics and
quantum effects in biological systems and their applications to energy transfer and sensing.
•
On the quantum information front, IT has proposed a new method to simulate synthetic
magnetic fields with photonic systems, namely with three-dimensional integrated photonic
circuits, developed in the context of IT project QuSim. Furthermore, we have shown how
quantum short-range channels can be made more robust to noise by performing regular
measurements on them, a counter-intuitive result yielding very good fidelities for quantum bit
transfer across spin chain channels.
•
Furthermore, we have found that continuous-time quantum walks on random networks yield
optimal quantum speed-up for spatial search. This was a very surprising and high impact result,
as this optimality was only believed to hold for very regular and symmetric networks. Moreover,
we were able to extend our result to show that it is possible to send a quantum bit of
277
information, with fidelity one, between two nodes that are not directly connected to each other,
as well as establish maximal quantum correlations between such nodes. Overall, our results show
that quantum information tasks can be very robust to spatial disorder, and open the way to
explore optimal quantum information transmission and processing in random networks
•
Finally, we also investigated quantum information theory in the relativistic regime, and found that
the degradation of quantum correlations between entangled parties subject to acceleration
varies for different initial states that all have the same amount of entanglement, revealing that it
is not only the initial amount of quantum correlations that is determinant for this loss of
information. We have also started investigating the capacity of black holes to process and leak
quantum information.
•
On the quantum effects in biological systems and energy transport front, namely in the context of
EU FP7 project PAPETS, IT is applying the semi-classical method to simulate the vibrational
dynamics of complex biomolecular networks, that it recently developed, to chromophoric
systems, both natural and artificial. Furthermore, we have found that it is possible to have
disorder-assisted quantum transport in sub-optimal decoherence regimes, contributing to further
enlight the understanding of environment-assisted quantum dynamics.
•
On the nanoenergetics and quantum thermodynamics front, we have obtained a method to
determine the minimal heat dissipation of quantum information erasure, and have successfully
concluded the EU FP7 project LANDAUER (obtaining “Excellent” in the corresponding final
review). Furthermore, we have started theoretical work on quantum refrigerators and on
quantum heats engines, including some based on vacuum forces, whose potential experimental
implementations we will also to investigate, namely in solid state systems based on graphene or
Nitrogen-vacancy centres in diamond. Finally, we have started to investigate the role of nonMarkovianity in the dissipation related to irreversible information processing at the quantum
level.
•
Finally, IT continued to play a key role in the coordination and consolidation of the FCT Doctoral
Programme in the Physics and Mathematics of Information (DP-PMI) during the DP-PMI’s second
year, as well as in the organization of its advanced courses in Quantum Information Technologies.
Furthermore, IT continued to organize the Quantum Computation and Information Seminar and
the Physics of Information Seminar, as well as the special colloquium delivered by Serge Haroche
(Nobel Prize in Physics, 2012) in April 2015.

4.4.3.3.8 Power Systems
•
Applied Electromagnetics
-
Computational electromagnetics
- An electromagnetic analysis of a Variable Inductor (VI) of double E-shaped was
developed. In the studied VI topology, a DC current was used to control the inductance
of the VI through a series of electromagnetic phenomena. Therefore, to conduct the
279
electromagnetic analysis, a Finite Element Analysis (FEA) software was used. Some 3D
VI models were built with the software. The obtained FEA results were analysed and
compared with different models and experimental results.
• Power electronics and systems
-
Resonant contactless energy transfer
- IPT systems for electric vehicle charging – Control strategies were implemented for
unidirectional IPT systems and resonant topologies with compensation were used.
Simulation and experimental results were obtained. The efficiency and the power
transference capability obtained by simulation were experimentally validated trough a
developed prototype. A controller placed on the primary side of an IPT system based
on a variable inductor was studied and simulated. This controller allows charging EV
batteries with a constant current. A half-bridge topology for on-board IPT chargers was
also researched.
-
Converters
- DC-DC converters topologies for EV applications - A variable inductor has been
implemented, which reduces the core size and improves the ripple content of the
inductor current by controlling the core saturation in a reduced-scale 1 kW
bidirectional converter prototype. Other developed research was the control and
magnetic core optimization of an isolated DC-DC converter. From this work a prototype
was built.
- Multilevel converters for green energy - It was prepared a test bench with a doubly-fed
induction generator, supplied by NPC converters. This setup is being used to develop
research activities on condition monitoring of wind generators and, so far, results
regarding rotor faults were obtained.
- Multilevel converters faults - The fault detection capability during power converter
operation has become an issue of paramount importance. Without a suitable
diagnostic method, a semiconductor open circuit can remain undetectable for a long
period of time, causing damage to the converter and for the system where it is
installed. Following this issue, a study regarding the impact of open circuit faults in
IGBTs of rectifiers and inverters that use a five levels NPC topology was investigated. A
280
simulation model for these type of converters was implemented in Matlab/Simulink®)
and validated experimentally with a prototype developed for this purpose.
- Uninterruptible power supply of double conversion - Over the last year several tasks
regarding the implementation of the control and diagnostic strategies in an FPGA were
developed. In order to get a predictive control technique with good performance and
faster failure detection in the UPS, the main goal of the developed programing tasks on
the FPGA has been the reduction of the sample time, taking into account their
hardware resources. At this time the goal is almost achieved and ready to be tested.
- Development of new control algorithms and strategies for Hybrid Solar PV-WindBattery solutions for power systems.
- Simulation Models of hybrid Electric Traction Systems/Fast Charging Stations Network.
-

- Predictive control – Predictive control algorithms for induction and synchronous
reluctance motors were developed and tested in simulation environment. This control
strategy was also tested in the simulation model of a regenerative and programmable
AC-AC source and some experimental tests have been conducted.
- Thermal behavior of a three-phase induction motor – This topic has been investigated
and a new motor operating condition was evaluated for eccentricity faults. A 2D finite
element model was developed and several experimental tests were performed. During
experimental tests, a previously designed data acquisition system was used to
simultaneously measure thermal, electrical and mechanical data.

mind its adaptability to other energy harvesting systems.
-

282
Funding
CRUP
Descript.
No projecto dos novos sensores submarinos profundos (OBS) é necessário ter em conta
os resultados das experiências realizadas com os dispositivos actualmente existentes as
quais demonstram que, de forma a conseguir-se uma maior versatilidade é
imprescindível dedicar mais atenção a uma série de aspectos que afectam a electrónica
e projecto de componentes, nomeadamente, a optimização da relação sinal/ruído. É
necessário identificar as diferentes fontes de ruído e caracterizá-las distinguindo os sons
hidrodinâmicos dos biológicos, industriais, sísmicos e térmicos. É necessário caracterizar
e minimizar o ruído eléctrico gerado pelo sistema de aquisição e pelo condicionamento
de sinal através de um processamento adequado. A interpretação dos perfis sísmicos
envolve o reconhecimento de certos padrões geológicos como falhas, zonas altamente
reflectivas, etc. que permitem identificar grandes zonas de textura comum,
frequentemente associadas com processos geológicos relacionados. Os algoritmos de
processamento, que utilizam técnicas tradicionais como a FFT, STFT, ondulas e filtragem
digital, requerem a experiência de um geólogo para a interpretação correcta dos dados e
para a extracção da informação desejada. Este processamento pode ser simplificado e
automatizado no caso de uma boa relação sinal/ruído, especialmente importante no
caso das ondas refractadas que apresentam um baixo nível de sinal em relação à onda
directa incidente. Do ponto de vista do processamento de sinal, os sinais de tipo
geofísico colocam problemas interessantes e têm sido bastante estudados, em particular
aqueles que aparecem na sismografia tanto activa como passiva. A razão fundamental é
que se tratam de sinais que não representam directamente as fontes que os geram
(ruído, interferência, dispersão de propagação) que não são unidimensionais e para os
quais o estímulo apresenta grandes limitações quanto ao tipo de sinais que se podem
utilizar com esse fim. Não é de estranhar portanto que a maioria das técnicas de
processamento tenha sido aplicada num sentido ou noutro sobre os sinais de origem
geofísica: deconvolução cega, separação cega, reconhecimento com redes neuronais,
ondulas para eliminação de ruído, etc. O principal objectivo do projecto centrar-se-à na
validação dos resultados obtidos empregando sismómetros profundos, focando a
actividade na caracterização e optimização do sistema de aquisição de dados. Estudando
e propondo novos sistemas de integração da informação em redes de sensores
distribuídos. Serão analisados e implementados os sistemas de interconexão baseados
em Ethernet e em barramentos Can com aplicação das normas IEEE1451.

Interoperable Monitoring, Diagnosis And Maintenance Strategies For Axle Bearings
Funding
EC/FP7
Descript.
The axle bearing damage process has safety and economic implications on the
exploitation of railways systems, as proved by the selection of this topic for inclusion in
the present call for research proposals of the FP7 of the EU. Axle bearing damage has
been the object of intense attention by railway operators and transportation authorities,
leading to a variety of approaches and systems currently in place to deal with the
problem. However in Europe there is some lack of standardisation which justifies R&D
work on condition monitoring and early diagnosis of axle bearings by technology
integration. Moreover the current European documents do not present any guidelines
for the maintenance management of the rolling stocks with regards to axle bearings,
which make the association of monitoring, diagnosis and maintenance an interesting
approach. The MAXBE project appears in this context and its strategic objective is to
provide validated and demonstrated concepts, strategies and guidelines for the
interoperable axle bearing monitoring and diagnosis that support the railway operators
and managers dealing with the threats imposed by the existence of axle bearing defects.
The consortium for the MAXBE project comprises 17 partners (industry, leading
universities, end-users and a SME) from 8 member states, representing operators, axle
bearing manufactures, key players in the railway community and experts in the field of
monitoring, maintenance and rolling stock. The presence in the consortium of one axle
bearing manufacturer, market leader in the field, and three operators and railway
managers, as end-users, is decisive for the enhancement and optimisation of the axle
bearing diagnosis and maintenance strategies and for the definition of the new proposed
approaches for the interoperability. The MAXBE project will have impact for the
reliability, availability, maintainability and safety (RAMS) of rolling stock and
infrastructure, focused on the axle bearings.

Title
INSPECT - Integrated Nano Sensor Probes and Electronics for Eddy Currents Testing
Funding
FCT/PTDC
Descript.
This research proposal aims to develop a state of the art Non-Destructive Testing (NDT)
system to overcome current testing limitations on some specific industrial applications.
The system will include a new eddy currents probe, combining coils, a Magnetoresistive
(MR) sensors array and Complementary Metal-Oxide Semiconductor (CMOS)
microelectronic circuits, which will work together with an eddy current generation
element. Since the probe aims to be efficient for both superficial (requiring high
frequency operation) and buried defects (requiring low frequency operation), coils have
the disadvantage of having a frequency dependent sensitivity, which is lower at low
frequencies. Moreover, coils also have a low spatial resolution, due to its millimeters
range size. While coils measure magnetic flux, MR sensors measure magnetic field thus
having a frequency independent sensitivity. Therefore, by adding MR sensors to the
probe, its scope of detection increases, and also its spatial resolution, since MR sensors
can have dimensions on the micrometer range. Other advantage of MR sensors is the
fact that they are usually produced using thin film technology allowing high resolution
and repeatability. In order to increase the number of MR sensors in the probe, CMOS
microelectronic circuits will be included to perform multiplexing and therefore reducing
the number of outputs. The CMOS circuit will also bias the MR sensors, and apply lownoise amplification and filtering. To cope with the new probe high data throughput, the
system will also include an high performance Digital Signal Processing (DSP) unit. The
DSP unit will be based on a Field-Programmable Gate Array (FPGA) and high speed and
resolution data converters. A scalable processing architecture will explore high
parallelism within the FPGA processing core to perform digital demultiplexing, filtering
and demodulation of the multiple sensors signals. Also, the DSP unit will configure the
gain, bandwidth and the sensors addressing mechanism by communicating with the
microelectronic circuits. Results will be displayed in a Graphical User Interface (GUI)
running on a computer connected with the developed system. Characterization and
testing on real and relevant NDT applications will evaluate the new system performance.

Title
Towards very efficient organic photovoltaic cells through utilizing liquid crystal phases as
electron-acceptors
Funding
FCT/PTDC
286
Descript.
We propose, as a solution to seek more efficient OPVs and reduce production costs, the
exploitation of discotic liquid crystalline (LC) phases as alternative acceptors to
fullerenes. Discotic LCs are excellent candidates for OPVs due to their good absorptivity
in the visible spectrum and for being homeotropically aligned by annealing and surface
effects. The LC phases will be designed to combine favourable characteristics, namely:
high absorptivity where the solar emission is more intense, electron-acceptor character
relative to poly(alkylthiophene)s, and ability to assemble in nanostructures with
enhanced charge mobility. To ensure the morphological stability of the resulting LC
supramolecular structures, they will be synthesised as cross-linkable materials. We will
deal with two classes of disc-like materials, both recognized as good electron acceptors,
and with tunable LUMO levels, from which new materials with LC properties will be
derivatized: electron acceptors from the class of fluorenes (Fs) and the N,N´Dicyanoquinone Diimines (DCNQIs). Whereas DCNQIs have only been explored as
crystalline conductive salts, electron-acceptors from the Fs class have never been
prepared as liquid crystal materials. Our workplan includes: i) screening among known
DCNQIs and Fs and selection of those with more favourable photophysical and electronacceptor character in relation to poly(alkylthiophene)s; ii) synthesis of new LC materials
as derivatives of those exhibiting more promising properties; iii) investigation of their
self assembly character and development of methodologies to build film morphologies
including the donor component; iv) characterisation of the active layers in terms of
photophysical properties; v) fabrication and characterisation of OPV cells.

Title
Interoperability and implementation of autonomous marine platforms for seismic
monitoring
Funding
Descript.
The study of seismic activity has played a key role in increasing the understanding of the
dynamics of the Earth and its internal structure. Variations in real time seismicity
provides knowledge of the state of local and regional stresses in the short and medium
term, essential information to study the potential seismic risk that may affect
infrastructures and population located in the area . Seismic information is obtained
indirectly from the knowledge of traveling time of seismic waves and their trajectories.
For this, it is important to record these waves with different azimuths using seismic
sensors. The resolution of these measurements depends on the coverage and number of
sensors capable of recording these waves and their arrival times. On land, the resolution,
and coverage is adequate at the regional level, and is relatively easy to be increased in
specific cases using portable seismic stations (e.g. for microseismic studies). However, it
is important to note that the dynamics of the lithosphere associated with the interaction
of tectonic plates happens mostly in ocean basins and margins, yet the distribution of
marine seismic stations is far from their equivalent in land, either because of the
technological complexity related with the environment, or the difficulties to access the
recorded data. Recent seismic activity, possible induced, in the Gulf of Valencia or the
intense underwater seismic activity associated with the eruption of El Hierro (20112012) shows the importance of controlling the seismicity located in the sea that is not
covered by the terrestrial monitoring networks. To overcome this problem, the
INTMARSIS project will integrate different measurement and data communication
289
technologies in a new design with a buoy on surface and a seafloor seismometer. The
integration of real time data generated by marine seismometers will be possible thanks
to the development of wireless communication systems, the increasing potential for
miniaturization of sensors, storage devices and data processing, which have opened the
door to a new generation of distributed intelligent sensor networks that are connected
by communication networks. To enable the exchange of instruments between different
systems and platforms is necessary the standardization of these. Therefore,
standardization should begin at the sensor level because this gives a good integration of
the information flow. In observing systems with a limited number of instruments, it is
always possible to individually integrate each instrument in the measurement system.
However, in the future systems of heterogeneous observation and dynamic variable, this
concept will not be practical. The joint efforts of the research team, and industrial EPOs
with extensive experience in the various technological challenges of the project, will
permit the design, construction and assembly of a new generation of interoperable
marine seismometers that will delivered acquired information in real time. This will
represent a significant advance over existing devices, decreasing the technological
dependence and promoting the development of own technologies.

Title
Remaining Life Evaluation of Catalytic Furnace Tubes
Funding
FCT
Descript.
The objective of this paper is to evaluate from the output surface the damage of the
catalytic tubes of the columns of the reformer furnaces in order to predict its remaining
life. Catalytic tubes are the most critical components in reformer furnaces. Reformer
furnaces are widely used in the petrochemical industry to produce hydrogen from
hydrocarbons. It is in the radiant tubes containing a catalyst that the hydrogen
production takes place, as a result of endothermic reactions between hydrocarbons
(mostly methane) and water vapor. These reactions proceed at a temperature range
between 800 and 900ºC and the working pressure in a reformer furnace is between 2
and 5 MPa. These are severe working conditions that cause structural damage in the
tubes. It is necessary to develop methods for the inspection of tube degradation and for
a realistic prediction of its residual life. Some analytical methods have been developed to
estimate reformer columns service life or the time to failure, as the assessment of
damage and advance planning of column replacement should be made to ensure that
failures or unplanned shutdowns are avoided. However, direct methods to evaluate the
probable extent of damage and remaining life in a particular furnace are always much
more preferable. Nowadays, direct tests are performed destructively by examining
metallographically the microstrutural changes and creep damage on a series of ring
290
samples cut along the length of single tube removed from the reformer furnace. The
objective of this project is to project and implement an in-situ measurement system to
inspect through a nondestructive testing (NDT) technique, based on eddy currents,
reformer tubes damages to infer about its remaining life. The eddy current method is
based on the excitation of the material with a time variable magnetic field. In this way,
the electromotive force developed inside the material will give rise to electric eddy
currents. These currents are related to the conductivity distribution of the body and
exhibit certain patterns that can be predicted by measuring the total magnetic field in
the vicinity of the material. In the presence of defects, such as cracks due material
fatigue, the eddy currents deviate from its normal geometrical configuration, and this
perturbation on the eddy currents can be sensed by magnetic sensors placed close to
them. This technique enables not only the detection of cracks due to material fatigue but
also the appearance of intermediate stages that are correlated with the micro-structural
changes that occur during service. This project deals with a challenging problem very
important for the petrochemical industry. It is to be developed in partnership with
colleagues from the Laboratório de Ensaios Não Destrutivos, Corrosão e Soldadura from
Universidade Federal do Rio de Janeiro. They shall provide us characterized samples
taken from reformer furnace tubes with different damages and degradation. The work
included within this proposal will complement their work on the failure analysis and
remaining life assessment of the tubes based on the microstructural observations they
perform using different techniques like light microscopy, scanning electron microscopy,
transmission electron microscopy and diffraction and carried out within a research
project supported by Petrobras. It is our belief that the success of this work in
partnership would enable our participation in future projects now that the agreement
with Instituto de Petróleo e Gás and Petrobrás is underway. 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, linking
different areas of knowledge, which embraces issues like: (1) technology development;
(2) image processing and recognition; (3) modeling and algorithms; (4) measurement
techniques. 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.

findings of the project will eventually mature into simulation tools that will positively
impact river (bio)engineering practices, the immediate innovations pertains essentially
to fluid mechanics and to instrumentation, comprising: - a new database of flows within
and over the bed of idealized vegetated streams; - a Navier-Stokes solver based on
Lagrangian SPH discretization, applicable to open-channel flows and flows within
multiply connected domains (porous media and vegetated regions); - a new timeresolved PIV and LIF instrumentation will be developed, remaining available, once the
project is terminated, to Portuguese and international research groups. The innovative
aspect of the instrumentation must be highlighted: the time-resolved PIV-LIF system is a
sophisticated measuring device that will create the conditions for major advances in
realm of fluid mechanics and mass transport with applications to environmental
problems.

meaningful application areas where the complexity of the phenomena involved goes
beyond the scope of standard approaches. The impact and relevance of the proposed
line of work should accordingly be measured directly by its foundational character with
respect to a better and deeper understanding of meaning in logics modeling complex
phenomena and, of necessity, suitable general forms of compositional reasoning.

Towards the Advisory Council for Aeronautical Research in Europe (ACARE) goals, which
intends to reduce aircraft CO2 emissions and fuel consumption by 50 % within the next
decade, the Clean Sky program has focused its intervention in several concurrent
developments, such as aircraft aerodynamics and weight, and highly efficient engine
concepts. In this framework, Snecma is leading the Clean Sky SAGE2 activities, to study
the development of an innovative concept based in a geared open rotor engine that will
294
end up as a breakthrough for the next 15 years, thanks to the improvements in the
propulsive efficiency, without the penalties of any duct drag. Along with several engine
subsystems and technologies that are being developed in the scope of SAGE2, conducted
by several Clean Sky ITD leaders, Avio Propulsione Aerospaziale is responsible for the
power gearbox, which is the focus of this bidding activity. As an innovative high
efficiency power gearbox is being developed, it is very important to keep the tracking of
as many early physical parameters as possible, in order to provide useful feedback data
for design processes optimization; during operation, similar parameters will allow the
aircraft to identify potential structural health problems, such as unexpected vibration,
temperature and pressure variations, and metal debris in the oil. In this RTMGear
activity, Active Space Technologies (AST) intends to develop a telemetric system based,
as much as possible, in proved technologies, while Instituto de Telecomunicações (IT)
will focus their research in innovative Surface Acoustic Wave (SAW) technologies for
measuring temperature and strain in rotating parts.

The invention of the “transfer resistor”, or “transistor” as it is know today, is considered
to be the greatest invention of the 20th century, as it forms the basis of all electronic
systems. The next technological revolution will come through self-organizing and selfprogramming circuits and systems, which are similar to biological brains in that they can
learn to perform tasks. The recently rediscovered Memristor offers a computational
substrate with plasticity, in which adaptive circuits can be efficiently implemented. This
Action is aimed at bringing together researchers of different backgrounds to work in
unison so as to overcome multidisciplinary barriers in the area of memristors. Bringing
together device designers, device modelers, circuit theorists, analogue and digital
designers, neuromorphic engineers and computation scientists will enable the
defragmentation of current research efforts and is likely the to bring then next
technological revolution. The creation of the hardware basis for future selforganizing/self-programming systems will really open up a wide range of application
areas and new industries, e.g. humanoid robots to look after the elderly, self-driven
vehicles etc.
