This group is divided in two different research groups: eXiT and ARLab.

eXiT is a research group (GRCT 41) of the Universitat de Girona integrated by professors and phD. students of

the Departament d'Electrnica Informtica i Automtica . The research activity is developed in the Institut d'Infor-

mtica i Aplicacions . The eXiT teaching capacity is developed in the IT Doctoral program (Dept. EIA / IGSOC).



8/50

eXiT group develops an active research in the field of process supervision with emphasis in the integration of me-thods and techniques to assess process behaviour from measurements and experience reuse based on the fo-llowing main points:

Case Based Diagnosis: Adaptation of Case Based Reasoning (CBR) methodology into the domain

of dynamic process with emphasis on diagnosis. Definition of similarity criteria between signals.Reuse of past experiences.

Multivariate statistical process control: adaptation of these formalisms to model, fault detection anddiagnosis of batch process.

Qualitative representation of trends: definition, formalization and development of numeric to quali-tative interfaces. Representation of signals as sequences of episodes necessary to deal with kno-wledge based approaches.

Knowledge discovering in data bases for situation assessment.

This research is clearly domain dependent. Nowadays, the activity is developed in the following domains:

Chemical and petrochemical process Waste water treatment plants

Electric Distribution System (Power Quality)

Electronic Circuits

Other recent research interest is in the field of Remote and Virtual laboratories. This is motivated by the necessityof testing and comparing experiences in shared configurable process and the teaching activity of the group.

eXiT website: http://exit.udg.es

Agents Research Lab is a research group (GRCT 69) that is concerned with the development and analysis of AI

techniques and control architectures for both agents and multiagent systems. The origin of our group is the ap-plication of Artificial Intelligence to control and supervision. In these issues, the group has obtained successful re-sults in the development of physical agents. Such agents have specific properties provided that they have a bodythat interact with the environment and need to adapt their behaviour to the new circumstances they encounter. Cu-rrently, we are exploiting these particular properties of physical agents to personalised agents. This involves, re-search on multi-agent architectures for user modelling and recommender systems, trust mechanisms for agentcollaboration, integration information frameworks and social networks. The group collaborates in innovation pro-jects in the industry within the EASY Center (CIDEM/X-IT network).

.Geometry

The GTP GeometryLib supplies a Multiresolution LOD (Level of Detail)Solution which addresses the shortcomings of previous approaches by

giving developers access to a complete package of solid technologywhich supplies

A fast image based simplification algorithm to efficiently cre-ate high quality MLODs without human intervention.

Multiresolution triangle strip generation taking into accounttopology and texture of the base model.

A memory & runtime efficient compressed multiresolutionmesh format that contains triangle strip information, avoi-ding the need for costly on-the-fly tristrip generation.

A new multiresolution model specially fitted for plants allowing for an incredible amount of close up detail for e.g.

leaves, while at the same time supplying simplified representations for the fast rendering of objects which arefurther away.

Visibility

In computer graphics, Visibility deals with the problem of rendering faster by rendering only the objects of the scene that can beseen.Existing solutions along that line employed in modern day 3D/game-engines are mostly based either on Portals or on Quakestyle PVS (potentially visible set). While these approaches have been successfully employed in commercial products for years,they nonetheless have considerable drawbacksThe GTP VisibilityLib overcomes these problems with a 2-phase strategy:

A solution which supplies precalculated visibility based on modern visibility research, also suited for outdoorscenes.

A solution which efficiently employs modern day graphic hardware to deliver on-the-fly visibility with minimaloverhead.

Illumination

Global Illumination is the field of computer graphics that deals with physically correct illumination. Usually this is associated withstochastic raytracing solutions taking hours to calculate a single picture.The GTP IlluminationLib brings physically correct rendering to the domain of re-altime graphics.

Effects that will be possible include:

Soft Shadow/Lighteffects

Dynamic Lightsources

Indirect Illumination

Reflections

Realtime Radiosity

High-Quality Materials (Metal,...)

Cloud Rendering

allowing for previously unseen levels of realism in 3D/game applications.

MOMARNET

The MOMARnet Marie Curie Research Training Network aims at strengthening the European approach to deepseafloor observatory science and technology, by reinforcing the links between fourteen European laboratories in

eight countries, by training a multidiciplinary group of young researchers, and by producing new science and pre-

paring for new seagoing cruises and seafloor experiments.

MOMARnet has two broad research targets:

Understanding the dynamics of slow-spreading ridge hydrothermal vents and their plumbing system(depth of seawater circulation, heat sources, feedback between volcanic, hydrothermal and seismicevents)

Understanding deep-seafloor hydrothermal ecosystems, including their distribution, role and variety

of organisms, life cycles, effects of changes in the hydrothermal outflow (temperature, flowrate,chemistry, etc.)


14/50

MOMARnet science will contribute to the implementation ofthe MOMAR (MOnitoring the Mid-Atlantic Ridge) interna-tional project of setting up a multidiciplinary sea-floor ob-servatory for monitoring hydrothermal vent environmentsalong the Mid-Atlantic ridge close to the Azores archipe-lago.

The University of Girona team will develop a semiautomaticsoftware that willproduce well navi-gated mosaics ofseafloor images, and establish a data bank of processed seafloor imagesfor the MOMAR hydrothermal sites. These data will be key to manage fu-ture MOMAR-related experiments. PhD student will develop software tocombine navigation data, images of the ocean floor, seafloor bathymetryand acoustic imagery. Mosaicing techniques (existing and developed wi-

thin this project) will be applied to build a geo-referenced image mosaic ofthe Lucky Strike hydrothermal site. This mosaicing software will be deve-loped in a flexible manner, so as to be expanded and applied to 3D-visionsystems, video imagery, and high-resolution acoustic systems used on cu-rrent ROVs and AUVs, and to other configurations that may be used in se-afloor surveys in the future

FREESUBNET - A European research network on key technologies for intervention autonomous

underwater vehicles

There are many unresolved scientific questions and equally many major strategic economic and social

development needs from an exploration of the seas around Europe. There is a pressing need for the

development of advanced technologies to explore and exploit in a consistent and better manner the

vastness of the oceans of the world.

Intervention Autonomous Underwater vehicles (I-AUV) have shown their potential for the acquisition

of marine data at extremely large scales and for the direct intervention in underwater structures without

the need for constant human interaction and supervision. Part of the technology required for their de-

velopment has proven to be feasible. An increased effort is now needed to further the advances already

made in the technology and to make the results more accessible to a wider range of commercial and

scientific end users. To this end it is necessary to create a critical mass of young researchers capableof bridging the gap between marine technology and science.


16/50

To achieve this FREESUBnet will first explore a set of applications with intervention requirements thus

allowing the focus of the research to be in the fields of Marine Science, Inspection of Wrecks & Ar-

chaeology, assessment of Energy systems and multi-disciplinary applications in Marine Science. In

this context, the network will study novel concepts of IAUV' leading to the identification and the deve-

lopment of the technologies needed to fulfil these tasks. The techniques for navigation, autonomous

underwater telemanipulation, vehicle control and mission management technologies, will be furtherexplored and developed to close the gap between state-of-the art IAUV technology and its applications.

FREESUBnet aims to meet its goals by establishing an international network of technology developers

as well as being inter-sectorial and deliver the technology to end-users from different and diverse dis-

ciplines.

ONE - Open Negotiation Environment

The ONE project is a STREP project funded by the European Commission under the DG-INFSO that is geared

towards SMEs in order to provide them with a trusted, secure and free of charge technological environment in

which they are able to create tactical and strategic alliances; for the ultimate goal of pursuing business opportu-

nities and growth.

The project allows organizations to create contract agreements in order to supply complex, integrated services

as a virtual organization (or coalition).

To keep up with the competition in digital markets SMEs have the need of developing alliances and collaborating

together in order to provide joint services and also to address large tenders.

ONE is structured into a coherent set of activities with a balanced mix of:

Research on economic, societal and user aspects

Research and development of enabling technologies and methods (driven by the above)

Research and development of enabling technologies and methods (driven by the sdfasdf

Trials and evaluation activities.



18/50

ONE will be achieved through a set of technology components which can be tailored to the needs of

a specific organization; conforming to its business requirements and adapting to its every requirement.

The project will deliver an open source platform for ne-

gotiation, driven by innovative business models andtechnologies; it will be implemented mainly as an inte-

gration of innovative research component, delivered wi-

thin the project, and existing with off-the-shelf

technology using already standardized information mo-

dels.

It will extend and leverage a more general purpose di-

gital ecosystem architecture. There will be a general ar-

chitectural framework developed for negotiation,

allowing the adaptation of the platform to many different

industry sectors.

Meta-modeling (through adoption of Model Driven Architecture ) is the approach that will be followed

to achieve the desired high level of abstraction, reuse and code generation. While the P2P architecture

will be based on existing open source technology, ONE will do produce innovative technologies in all

the layers above.

ONE will provide a negotiation mechanism that is reusable in different application and service domains

providing a great level of flexibility and allowing users for example to create negotiation processes

also for other goals like for example qualification or certification processes.

The ONE platform will actively support the human negotiators by exploiting automatic learning techni-

ques applied to the goal of learning the best negotiation strategies in a multi-agent environment. Op-

timized strategy would be suggested through a learning process based on the observation of user

behavior, other partners actions as perceived by the user and concurrent running negotiations.

ONE supports a model of collaboration and trust based on the idea of "collaborative multi-agent

systems", where agents can work and learn with other trusted agents and develop collaborative lear-

ning schemes. We will develop models of information and knowledge sharing, taking into account pri-

vacy concerns, based on a model of multiple agent clusters, characterized by different levels of trust.

The policy learning algorithms will be based on the observation and storage of real interactions bet-ween the user and the negotiation service and between the user and other players (Trust), as these

are performed in the Negotiation Execution Environment.

The ONE negotiation environment will support technical and non-technical users in specifying strate-

gies and rules for negotiating terms of service delivery. It will provide a distributed and peer-to-peer

platform for fully automated execution of negotiations based on knowledge sharing and self-learning.

Fault Diagnosis of Electrical Distribution Networks Based on Cases and Models

The project proposes a case based reasoning (CBR) strategy to diagnose electric faults. Cases will be built from disturbances,collected by power quality monitoring instruments (events) located at substations, and register reporting all the action performed

in the network gathered in the network control center.

Setting dependences between waveform attributes and its causes will be used in the definition of cases. Disturbance propagationmodels and feature extraction strategies will be analysed in order to represent cases consistently. This analysis will be alsouseful in the definition of Retrieval, Reuse, Revision and Retain tasks needed to build the CBR cycle.

The Case Based Diagnosis system will be impro-ved in the location step by the integration of a mo-dule to estimate the distance to faults in thedistribution network. This module will be based inthe estimation of the impedance during the fault

and the use of algorithmic techniques, involving themodel of the line, to estimate an equivalent fault dis-tance. The combination of this estimated distanceand origin from retrieved cases in presence of anew disturbance will enhance the diagnostic.

Finally, an extension of cases to sequences of themis proposed to predict catastrophic faults. The re-cognition of a disturbance as part of a one of thesesequences will be interpreted as a symptom to pre-dict a possible fault.

AUTOMATED FAULT DETECTION, DIAGNOSIS AND TOLERANCE IN UNCERTAIN AND DISTRIBUTED

SYSTEMS

Fault detection, diagnosis and tolerance in systems allow maintaining the process in a high level of production and reliability. Thepresent techniques show problems when they are applied to uncertain and distributed systems. For this reason, they are beingresearched in a very active way to develope new techniques.The most important objectives of this project are to decrease thehigh false positive and false negative rates, to improve the computacional efficency of fault detection and diagnosis and to au-tomate the identification of components that are the cause of the failures.

These problems for the uncertain systems can be treated using the classical diagnosis approaches: the FDI (Fault Detectionand Isolation) community, whose foundations are based on engineering disciplines, such as control theory and statistical decisionmaking, and the DX (Diagnosis) community, whose foundations are derived from the fields of Computer Science and ArtificialIntelligence and bridging the methodologies of the FDI and DX Communities (Bridge). Firstly the project proposes this last ap-proach to automate fault diagnosis in these systems. The Research Group in Girona has developed the SQualTrack tool forthe fault detection of these systems and this project proposes its extension for diagnosis with techniques derived from modal in-terval analysis. We consider that it is important the coordination with the Quivir (Sevilla and Huelva University) Group that is also

studying these same systems using constraint satisfaction techniques, guaranteed methods and data-mining techniques. Es-pecially, the last techniques can work without the knowledge of the model and can deal with the empiric data (data-based diag-nosis). These techniques are being validated in real systems.

In distributed systems, firstly this project addresses the general problems associated with automatic determination of the allocationof sensors to improve the diagnosticability of the distributed systems. Secondly we will develop a framework for self-diagnosisof distributed systems where we take into account the persistency of the different models and different improvements based onclustering and distributed constraint satisfaction techniques.

Finally, we consider that the dependability and fault tolerance are important in the systems. So, we propose the modelling of re-aliability and security properties and the identification of the faults in the monitoring systems. We will develop different algorithms

that take this information and automatically obtain the fault diagnosis and choose recovery actions using planning and re-planning. It can hopefully provide a foundation for building realistic automatic dependability and tolerance systems.

Multilayer Mechanisms for Resource allocation and Restorable Routing in GMPLS-based core networks

(M2R3)

nternet Protocol (IP) networks currently operate over a semi-static transport infrastructure, where the management is concen-

trated within the IP layer. With the introduction of Multiprotocol Label Switching (MPLS), an intermediate circuit-switching com-

munication layer is added together with its corresponding management plane. Moreover, the development of optical technologies

such as Dense-Wave Division Multiplexing (D-WDM), supporting wavelength switching, etc., allow new multilayer networks tobe constructed with an unprecedented degree of freedom and flexibility.

Nevertheless, the management of such multilayer networks is more complex and presents potential instabilities. The complexity

of the evaluation of the percentage that should be applied at each management layer, i.e. IP, MPLS or optical, presents a sig-

nificant challenge. We denote as activation degree such percentage which will depend on multiple conditions such as: the to-

pology of the network, types of traffic, the load of the network and the desired degree of protection.

The main objectives of the M2R3 project are the investigation of the following components: quality of service routing mechanisms,

routing with protection and a dynamic resource management. They must be developed and configured according to the required

activation degree. The project will provide novel tools that will enable network operators to suitably manage their networks in a

holistic manner, allowing the various technologies to operate in concert rather than inefficiently or even in conflict with each other.

To the best of our knowledge, the approach we present to resolve this complex management challenge has not been undertaken

in other proposals.

NetMould. Efficient technology integration of the mould in knowledge based networks

This projects aim was to elaborate a viability study of a system that retains the know-how of a traditional industrial sector in ahigh technology level such as plastic injection companies (mould builders, parts designers or plastic injection plants), which isgoing through difficulties due to the relocation process.Netmould demonstrated that it is feasible to develop a solution to provide the sector with a technology that has an added valuedirectly incorporable to moulds and its environment(the plant or laboratory). The key is to shift the view-point to a mould-centric vision that transforms thecurrently passive tools into network enabled ele-ments with intelligent knowledge embedded.The results of the project show that this emerging

technology assures a competitive advantage (re-duction in production time and errors), a quality en-hancement (thanks to preventive diagnosisenhanced by sharing the information on-line) andan increase in usability (process monitoring, remotecontrol).The tasks of the UdG team have been oriented toimprove the diagnosticability of moulds using statis-tical techniques. Multiway Principal ComponentAnalysis has been used to model injection of plasticpieces and those models have been exploited todetect and diagnose abnormalities in future injec-tions.

Development of a prototype to assist fault location in distribution networks

This project aims at developing a prototype tool to assist fault lo-

cation in distribution networks using the companys existent kno-

wledge about network and perturbation logs (wave shapes and

events) as well as operations and actuations on the network re-

gistered in the control center.

Two main aspects in the monitorization of the power quality areexpected to be improved:

Analysis of disturbances propagation, conciliating theincidence logs (from network control center) with thedisturbances registered in different locations of the net-work (using quality registers)

Location of faults occurred in the distribution. Asystematic analysis of waveforms of disturbances using

algorithmic methods of fault location will allow reducingcurrent location times.

The final purpose is to characterize and systematically eva-

luate perturbations in the distribution network using previous

logs and its reutilization to perform a fast location and diagno-

sis of the network distribution faults.

Fault location consists in finding an accurate estimation of the

zone in which the fault has occurred, using the measures of

the waveform of the registered event and the network topo-

logy.

Reference network in Advanced Production Techniques

The main objective of the task carried out by VICOROB Research Group in this project is developing a set of prototypes of Iden-tification and Positioning Systems.

The final result of the project will be the development of different solutions that allow identifying the different parts that constitute

an industrial kit, and obtaining the position and orientation with enough accuracy to allow picking these parts using a manipulator

or grasping system. Usually, the different parts arrive all together to the inspection point in a disordered bunch, and some parts

can present different kinds of deficiencies.

Recognition System: different computer vision algorithms will be developed to identify the different parts that can appear at the

inspection point. This system will be able to extract geometric information from the images and compare it to the corresponding

CAD models in order to determine whether the part is faulty or not, or if the visual information obtained is adequate or more ad-

ditional images are required.

Position and Orientation of the parts: a robust computer vision algorithm will be developed to determine position and orientation

of the previously recognized part referred to a determined reference frame.

ANALYSIS, IDENTIFICATION AND CONTROL OF MECHATRONIC SYSTEMS WITH HYSTERESIS AND

FRICTION. APPLICATION TO PIEZOELECTRIC AND MAGNETORHEOLOGICAL ACTUATORS

Hysteresis and friction are nonlinearities encountered in various systems in science and engineering areas. This project dealswith mechatronic systems equipped with actuators based on smart materials, in particular piezoelectric and magnetorheological.These actuators are particularly useful in high performance control applications, due to their high precision and fast response.These advantages can only be exploited through a fine constructive process and if appropriate theoretical tools are available.Indeed, these actuators have a complex dynamics with presence of nonlinearities, hysteresis and friction being the most signi-ficant. Due to the high performance required in closed loop, these actuators are prone to the uncertainties in the models and inthe operation conditions. Thus it is essential to have appropriate analytical tools for the study and robust identification of their dyna-mic models. Moreover, the design of controllers needs the use of advanced nonlinear control theories to be able to guaranteerigorously the narrow specifications in terms of stability, precision and robustness.This project follows three complementary research directions:

Development of new theoretical tools for dynamic analysis, robust identification and control of systems withhysteresis and friction;

Construction of prototypes of piezoelectric and magnetorheological actuators integrated in mechatronic systems;

Experimental validation in these systems of the developed methods and algorithms.

The project will consider two problems: micropositioning control and vibration reduction, which have special practical interest no-wadays in areas as automotive industry, mechanics, aeronautics, aerospace and civil engineering, as well as in nanotechnolo-

gies.

AIRSUB - Underwater Robotics Industrial Applications

This project proposes the design and development of the necessary

technologies for the adaptation of the prototypes of the low-cost un-

derwater vehicles GARBI-ROV, GARBI-AUV , URIS and RAO II fortheir use in shallow waters. First, in collaboration with industry, a ca-

talogue of industrial applications -feasible for low-cost underwater

vehicles- will be created. For each and every of these missions, the

adequate scenario will be established, as well as a mission prelimi-

nary schedule. Next, the project will be focused in 3 industrial appli-

cations:

Dam inspection of hydroelectric plants

Underwater cable and pipe inspection

Inspection of harbours.



27/50


Every one of these applications will be leaded by one of the 3 subprojects, will be associated to a market-leader

company in its field, and will end with a practical demonstration.

For dam inspection we propose the use of an AUV which could

scan the dam wall at the same time it acquires a video, registe-

ring its state. This video will be processed off-line to build a ge-oreferenced photo-mosaic, which will allow the company

engineers to gain a global view of the condition of the dam.

Analysing this mosaic, successive inspections can be scheduled

to evaluate selected areas with higher resolution, as well as

studying its temporal evolution. This inspection technique will be

applied both to both the grilles of intake and the penstock gallery.

Cable and pipe inspection will be carried out using an AUV that

will first submerge and detect the cable. Then, the robot will be

guided by means of the automatic visual tracking system. Along

the mission, the AUV will acquire, in a first phase of the project, a large set of images that will be processed off-

line (building of mosaics, analysis of an expert, etc.). In a second phase the AUV will filter the acquired images,keeping those images which show defects of the cable/pipe and annotating their localization. In this way, the com-

pany engineers can concentrate in the suspicious areas along the inspected section of the cable/pipe. Finally, for

the inspection of the breakwaters walls of harbours a ROV will be used. This robot will acquire images which will

be used to build a georeferenced mosaic. Fuzzy techniques will be used to localize faults and anomalies in the

moles, such as their temporal degradation.

Virtual Prototyping for Architectural Projects

The aim of the Project is to create a tool for helping the professionals of building design and architects.

The base of the work is the experience of the different research groups that belongs to CERTAP in topics such

us computer vision, vectorial designs generation from hand made layouts, computer assisted design, illumination

and generation of realistic images and virtual reality. As we said before, the final objective of the project has been

to obtain an immersive tool for supporting the professionals the design of buildings. The opinion of the professio-

nals had been considered in all the steps of the development of the project. The main characteristics of the de-veloped tool are:

2D sketch generation and the 3D model from hand made layouts. At this step, it is necessary tot take

into account buildings with different levels, stairs and different kinds of ceilings.

Realistic Illumination with ambient simulation (using radiosity), using simulation of natural and arti-

ficial light. The application offers the possibility to visualize the digital model surrounded by images

belonging to the reality.

Analysis and inspection of virtual prototypes generated by the system in low cost virtual reality plat-

forms (stereoscopic table) or using standard computers equipped with 3D immersive devices.

Tools of remote working that allows the cooperative inspection and analysis between different teams



30/50

working, using stereoscopic tables, in different locations.

The work developed by the VICOROB research group of the UdG has been:

The architect provides the application with a hand-made sketch, and then the application generates a full 3D

model of the building. Once the 3D model has been generated, the professional has the option to add texture and

simulate illumination (natural and artificial), being able to obtain realistic renderings. On the one hand, the resultscan be used by the architects to observe and adjust different aspects of the building at pre-project stage and, on

the other hand, to help the architects interact with the customers.

This task includes a sub-application that allows recovering the texture from an object of interest that appears in a

real scene. This real texture could be projected over virtual surfaces belonging to the model (walls, roofs, )

using the adequate scale.

Developing Distributed Computing Techniques for Scheduling. Application to Transport Problems

This project aims at the development of distributed computing techniques and multi-agent systems for the resolution of constraintsatisfaction and optimisation problems (CSP, COP), these techniques particularly guided towards planning and scheduling pro-cesses. So that, it is a coordinated project in which two research groups work together with complementary experience on: (i)CSP techniques, distributed CSP, planning and scheduling and (ii) distributed and open frameworks, multi-agent systems andcoordination mechanisms. Furthermore, the integration of planning and scheduling processes is considered in the CSP frame-work. The scientific-technique objectives are very relevant and important allowing us to manage problem typologies in whichtraditional techniques are not appropriate. Additionally, in the research project it is sought to apply and evaluate the developed

techniques in evaluation environments broadly contrasted in the scientific community and, mainly, with two concrete and realframeworks based on rail transport and intercity transport in which it is maintained respective agreements of collaboration.The main objectives of the project are:

Development of scheduling techniques that integrate algorithms from operational research, topological methodsand intelligent techniques oriented towards the efficient treatment of complex scheduling problems.

Extend the applicability of constraint satisfaction techniques with both multi-agent techniques and distributed ap-proaches of satisfaction problems.

Development of an integrated architecture for planning and scheduling.

Application of the architectures and techniques in real environments (train infrastructure planning, crew sche-

duling for road transport) as well as in scientific benchmarks (Pacifica).

Interfaces avanzadas para la interaccin transparente con modelos altamente complejos en entornos de

realidad virtual

The development of effective user interfaces for virtual reality environments must face different challenges. Not

only must one evolve new paradigms that are adequate in those environments, but they must also be minimally

invasive (not to spoil the immersion illusion), and they must rely on an adequate support from the underlying mo-

dels and model-handling functions, so that the maximum complexity of usable scenes is not seriously limited.

This project aims at pushing further the state of the art, developing new techniques at the modelling level (to allow

handling models like the most complex currently available, which are too long to fit in memory for a reasonably

configured workstation). It also aims at perfecting the state of the art concerning the interfaces themselves, de-

veloping specific techniques adapted to the interaction in those media, and especially for remote collaboration.

Moreover, the results will be tested developing specific prototypes to verify the usability of the proposed techniques

from the point of view of experts in three application areas, chosen amongst those that may benefit the most from

the expected results.,

Adaptation based on machine learning, user modelling and planning for complex user-oriented tasks

(AdaptaPlan)

This project has two main objectives. On one side, to analyze the capability of automatically solve tasks that needthe integration of planning, machine learning and interaction with differentagents (human or software) to ubiquitously and dynamically adapt to theevolving needs of the context. Thus, we have defined a set of scientific goalsrelated to user modelling, machine learning, planning, multi-agent systems,and ubiquitous computing.

On the other side, we would like to benefit from the two-fold experience ofthe project researchers, both as users and developers, in a specific applica-tion domain: university education. In this domain, tools that integrate pre-vious techniques are strongly needed. This applied objective consists in thedesign and development of an architecture that provides services to bothstudents and lecturers in the new education tasks that are defined by the European Space for Higher Education.

Improvement and Application of the Game Technology in Virtual Reality and web con-

tents

Cutting-edge technology in the field of Computer Graphics is currently found in 3D engines for computer games.

This is due to the successful combination of research conducted by universities with the traditional techniques used

in the digital games sector. While this technology was first developed for computer games, it is expanding its

scope of application to include other sectors which are less developed as far as realistic rendering is concerned.

Virtual Reality and 3D web content are the sectors which show the greatest interest in incorporating the new tech-

nologies. Therefore the purpose of this project is twofold: To continue the research on computer games techno-

logies carried out in the project TIC2001-2416 and to apply the new technologies to the fields of Virtual Reality

and 3D web content.

The objectives of the project are: Improve videogame technologies in the fields of illumination and geometry

Extend videogames technology to Virtual Reality and 3D Web

Transfer scientific results to industry

Development of a glucemic prediction and insulin dosage-aid system for patients with

diabetes mellitus I (INSULAID)

Diabetes mellitus type I is a chronic disease of great individual and social impact which affects a great number of

people. It produces important damages in organs like eyes, kidney, heart, etc. leading to blindness, renal insuffi-

ciency, heart attack, etc, as well as a significant reduction in life expectancy. These facts are directly related to the

glucose levels in blood. The glucemic control in normality levels is the main objective of the treatment for diabetes

mellitus I.

The development of glucemic predictive models will allow a better metabolic control and, thus, reduce the com-plications of the disease. The metabolic model of the glucose due to Cobelli is nowadays widely validated in clinic

experiences. This model is non-linear and with more than 30 parameters to identify. The objectives of this project

are the parametric identification of this model for particular patients and the development of a training and simu-

lation system for guaranteed prediction of patients glucemia. Based on it, an insulin dosage-aid system will also

be developed. With these two systems the quality of life and life expectancy of the patient will be increased. For

it, techniques for the resolution of constraint satisfaction problems in continuous domains will be used. These

ones have experimented great advances due to the interval methods and combination with programming and op-

timisation techniques.

Development of an Intelligent Control System applied to a Sequencing Batch Reactor

(SBR) for the removal of Organic Matter, Nitrogen and Phosphorous

.This project is focused on the improvement of the control

system applied to sequenced batch reactors developed in the

project DPI2002-04579. The promising results obtained in the

previous project allow to consider the development of a more

ambitious control system to improve the overall process per-

formance and adapt it according to the influent water charac-

teristics.On the one hand, the research into the operating conditions will

be extended to cover the simultaneous elimination of Organic

Matter, Nitrogen and Phosphorous. In this way, the necessary

knowledge about the relationship between trends of on-line

variables and changes in the process will be obtained. Then,

from this knowledge, a control system to optimize the duration

of each stage will be implemented by means of an on-line de-

tection of critical points.

On the other hand, an Intelligent Control Module will be developed and implemented to diagnose the evolution of each batch

and to optimize the schedule in order to minimize the effect of the influent water variability.

Development of a Modular System to Build Georeferenced Photo-mosaics of the Ocean

Floor

In this project we propose the development new algorithms and techniques for the automatic construction of ocean floor photo-mosaics. Photo-mosaics allow the geological analysis of ocean floor morphology and hydrothermalism of selected areas. Like-wise, underwater photo-mosaics provide high quality images of specific areas for the study of biological communities.

The works which have been carried out up to now in the field of auto-matic construction of photo-mosaics have been limited to processingplanar environments, while most of the regions of interest for the scien-tific community are located in areas with 3-dimentional relief. For thisreason, research and development of new algorithms is a must to en-able simultaneous photo-mosaicking and estimation of underwater 3Drelief. On the other hand, none of systems described in the literature isable to automatically build large-scale photo-mosaics, due to the accu-mulated drift as the mosaic increases its size. In this project we proposeto develop new sensor fusion strategies to take advantage of all the in-formation available from the on-board sensors to automatically buildbigger and more reliable photo-mosaics.Finally, the proposed system should be modular and flexible, to adaptto a wide diversity of underwater vehicles equipped with various types

of sensors. Such a system will allow the analysis of the temporal evolution of both existing ecosystems and morphology of the

underwater terrain.

Implementation of a method to detect faults in loudspeaker lines

The main objective of this contract has been the study and implementation of a method to detect faults in louds-peaker lines. This method has been based in the addition of certain frequencies to the reproduced sound so thatthey can be recovered a posteriori. This way it is possible to identify problems within the line.In the first stage of the project we have carried out a theoretic analysis of the viability of such method using the

signal processing tools included in Matlab.In the second stage we have used a commercial DSP together with its programming environment in order to eva-luate its viability to face the problem. We have designed and build the hardware modules needed by the system,developing a module for analogical-digital conversion and a module for input/output that have been both integratedin the evaluation board.Finally we have implemented different software modules to run the application, that perform different tasks suchas generate, send, recover and filtrate signals, as well as calculations to determine variations in line load.

SAUC-E Team

SAUC-E is the acronym for Student Autonomous Underwater Challenge - Europe.

SAUC-E is a competition for European students to foment the investigation and development in underwater tech-

nology.

At the moment, there are 8 teams already inscribed in the competition:

University of Bath

International University Bremen


University of Glasgow

Heriot-Watt University

University of Leicester

University of Nice Sophia-Antipolis

Southampton University

As the first event of its kind was held in the UK 2006, the Student Autonomous Underwater Challenge Europe

(SAUC-E) proved a huge success. Seven university teams competed at the state-of-the-art underwater stage at

Pinewood Studios (www.pinewoodshepperton.com) with vehicles they had designed and built themselves.
