Ferrer i Cancho, Ramon (Date of defense: 2003-12-12)
Here, old and new linguistic universals, i.e. properties obeyed by all languages on Earth are investigated. Basic principles of language predicting linguistic universals are also investigated. More precisely, two principles ...
Panagiotidi, Sofia (Date of defense: 2014-09-29)
As distributed electronic systems grow to include thousands of components, from grid to peer-to-peer nodes, from (Semantic) Web services to web-apps to computation in the cloud, governance of such systems is becoming a ...
Beacco, Alejandro (Date of defense: 2014-12-11)
Nowadays crowd simulation is becoming more important in computer applications such as building evacuation planning, training, videogames, etc., presenting hundreds or thousands of agents navigating in virtual environments. ...
Tarrés Puertas, Marta Isabel (Date of defense: 2014-12-18)
The evolution of constraint based geometric models is tightly tied to parametric and feature-based Computer-Aided Design (CAD) systems. Since the introduction of parametric design by Pro/Engineer in the 1980's, most major ...
Muñoz Gama, Jorge (Date of defense: 2014-12-19)
In the last decades, the capability of information systems to generate and record overwhelming amounts of event data has experimented an exponential growth in several domains, and in particular in industrial scenarios. ...
Tosi, Alessandra (Date of defense: 2014-12-19)
Over the last few decades, data analysis has swiftly evolved from being a task addressed mainly within the remit of multivariate statistics, to an endevour in which data heterogeneity, complexity and even sheer size, driven ...
Oriol Hilari, Marc (Date of defense: 2015-03-19)
Service Oriented Computing (SOC) has been established in the last recent years as a successful paradigm in Software Engineering. The systems built under this paradigm, known as Service Based System (SBS), are composed of ...
Garcia Gasulla, Dario (Date of defense: 2015-04-23)
The first chapter introduces an approach to machine learning (ML) were data is understood as a network of connected entities. This strategy seeks inter-entity information for knowledge discovery, in contrast with traditional ...
Pérez Sala, Xavier (Date of defense: 2015-04-29)
This dissertation formalizes the construction of multi-view 2D shape models from 3D data. We propose several extensions of the well-known Procrustes Analysis (PA) algorithm that allow modeling rigid and non-rigid transformations ...
Esposito, Gennaro (Date of defense: 2015-06-17)
By using Reinforcement Learning (RL), an autonomous agent interacting with the environment can learn how to take adequate actions for every situation in order to optimally achieve its own goal. RL provides a general ...
Lluís, Xavier (Date of defense: 2015-07-13)
Syntactic Dependency Parsing and Semantic Role Labeling (SRL) are two main problems in Natural Language Understanding. Both tasks are closely related and can be regarded as parsing on top of a given sequence. In the ...
Larraz Hurtado, Daniel (Date of defense: 2015-07-28)
This thesis addresses the development of techniques to build fully-automatic tools for analyzing sequential programs written in imperative languages like C or C++. In order to do the reasoning about programs, the approach ...
Theoktisto, Víctor (Date of defense: 2015-11-25)
The present document exposes a different approach for haptic rendering, defined as the simulation of force interactions to reproduce the sensation of surface relief in dense models. Current research shows open issues in ...
Vilamala Muñoz, Albert (Date of defense: 2015-12-18)
Malignant tumours of the brain represent one of the most difficult to treat types of cancer due to the sensitive organ they affect. Clinical management of the pathology becomes even more intricate as the tumour mass increases ...
Gómez Sebastià, Ignasi (Date of defense: 2016-01-27)
With the growth of the Internet, computational systems have become more and more complex, often including complicate interconnected networks of autonomous components. The need to bring some organisational structure into ...
Cerveró Abelló, M. Àngels (Maria Àngels) (Date of defense: 2016-01-29)
Techniques devoted to deform 3D models are an important research field in Computer Graphics. They can be used in differentstages: the modelling phase, the animation process and also during some special simulations. ...
Civit Flores, Óscar (Date of defense: 2016-02-01)
This thesis focuses on the interactive simulation of highly detailed deformable solids modelled with the Corotational Finite Element Method. Starting from continuum mechanics we derive the discrete equations of motion and ...
Prat Masramon, Gabriel (Date of defense: 2016-02-01)
In this thesis we study feature subset selection and feature weighting algorithms. Our aim is to make their output more stable and more useful when used to train a classifier. We begin by defining the concept of stability ...
Ramírez Flores, Jorge Eduardo (Date of defense: 2016-02-04)
In the field of computer animation the process of creating an animated character is usually a long and tedious task. An animation character is usually efined by a 3D mesh (a set of triangles in the space) that gives its ...
