Marco-Sola, Santiago (Date of defense: 2017-09-20)
One of the outstanding milestones achieved in recent years in the field of biotechnology research has been the development of high-throughput sequencing (HTS). Due to the fact that at the moment it is technically impossible ...
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 ...
Sabir, Ahmed (Date of defense: 2020-11-10)
This thesis addresses the problem of improving text spotting systems, which aim to detect and recognize text in unrestricted images (e.g. a street sign, an advertisement, a bus destination, etc.). The goal is to improve ...
Madhyastha, Pranava Swaroop (Date of defense: 2017-07-25)
There has been an exponential surge of text data in the recent years. As a consequence, unsupervised methods that make use of this data have been steadily growing in the field of natural language processing (NLP). Word ...
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 ...
Oliva Martínez, Ramon (Date of defense: 2016-11-28)
In order to create autonomous characters it is necessary to solve the problem of moving agents between two locations, at both the global and local navigation levels. Global navigation has two main components: the path ...
Martínez-Fernández, Silverio (Date of defense: 2016-06-23)
Background: Software reference architectures are becoming widely adopted by organizations that need to support the design and maintenance of software applications of a shared domain. For organizations that plan to adopt ...
Navas Palencia, Guillermo (Date of defense: 2019-07-22)
In this dissertation, we investigate new methods to obtain uniform asymptotic expansions for the numerical evaluation of special functions to high-precision. We shall first present the theoretical and computational fundamental ...
Coma Puig, Bernat (Date of defense: 2022-03-02)
In recent years there has been an increase in the use of artificial intelligence and other data-based techniques to automate decision-making in companies, and discover new knowledge in research. In many cases, all this has ...
Cortés Martínez, Atia (Date of defense: 2018-07-20)
The ability to walk is typically related to several bio-mechanical components that are involved in the gait cycle (or stride), including free mobility of joints, particularly in the legs; coordination of muscle activity ...
Gkatzioura, Anna (Date of defense: 2018-11-23)
Current recommender systems aim mainly to generate accurate item recommendations, without properly evaluating the multiple dimensions of the recommendation problem. However, in many domains, like in music, where items are ...
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 ...
Oriol Hilari, Xavier (Date of defense: 2017-07-11)
Ensuring the data correctness of some information system is a crucial task. So, software engineers specify sets of integrity constraints that should be satisfied by the system's data. These constraints, however, can be ...
Surinyac i Albareda, Jordi (Date of defense: 2016-02-05)
Present systems for the acquisition of medical images are providing better and better resolution images which end up in bigger amounts of data, even in scenarios with learning or training purposes. Interactive inspection ...
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 ...
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 ...
Ferrés Domènech, Daniel (Date of defense: 2017-11-29)
Geographical Information Access (GeoIA) can be defined as a way of retrieving information from textual collections that includes the automatic analysis and interpretation of the geographical constraints and terms present ...
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 ...
Ruffini, Matteo (Date of defense: 2019-02-14)
Learning latent variable models is a fundamental machine learning problem, and the models belonging to this class - which include topic models, hidden Markov models, mixture models and many others - have a variety of ...
Taymouri, Farbod (Date of defense: 2018-12-21)
Conformance Checking is a new research discipline devoted to identify deviations between business process models and their real executions. Identifying deviations boils down to the notion of alignment conceptually. An ...
