Les plataformes d'intercanvi de recursos multimèdia contenen grans quantitats de contingut creat pels seus usuaris. Habitualment, aquest contingut no està ben anotat. En aquesta tesi, proposem mètodes per ajudar els ...
This thesis explores the problem of compatibility between generations in the field of Digital Television, and proposes solutions to this problem. Since its inception, the DTV has been under development without taking ...
Collaborative Learning is the pedagogical approach that considers social interactions as key means to trigger rich learning processes. Collaborative Learning Flow Patterns define best practices to orchestrate collaborative ...
En aquesta dissertació es fusionen dos dels temes tradicionals de la Visió per Computador: la segmentació i el seguiment d'objectes. Per a la segmentació s'utilitzen mètodes basats en "Active Contours (AC)" i per al seguiment ...
The objective of this thesis is to provide a temporal analysis of the structural and interaction dynamics of large evolving graphs. In this thesis we propose new definitions of important graph metrics in order to include ...
Undoubtedly, spectrum scarcity constitutes the main bottleneck of current wireless networks. It is therefore imperative to move beyond the sub-6 GHz band in order to overcome this limitation. Toward this direction, terahertz ...
The human brain is undoubtedly the most complex product of evolution. Understanding how complex behaviour is generated by the intricacy of hundred billion of neurons and synapses fascinated scientists and philosophers for ...
Animals excel in skilled motor behavior, especially when compared to arti cial systems. Several adaptive and predictive motor control frameworks have been proposed to account for such performance, but the underlying ...
The mammalian visual system has a remarkable capacity of processing a large amount of information within milliseconds under widely varying conditions into invariant representations. Recently a model of the primary visual ...
Oscillations at theta frequency (4-7 Hz) have been hypothesized to play an important functional role in brain processes associated to working memory. In this thesis, I investigate how the systematic manipulation of different ...
Actualment, no hi ha consens científic respecte a la informació representada en la activitat de les célules del hipocamp. D'una banda, experiments amb humans sostenen una visión de la funció de l'hipocamp com a un sistema ...
This dissertation presents an empirical study on the information structure– prosody interface based on: (i) a formal description of hierarchical thematicity within a systematic language model for natural language generation ...
The analysis of the interconnection status-quo between content providers and Internet Service Providers (ISPs) is essential to understand the evolution of the Internet ecosystem. In the last years we have witnessed a ...
Brain circuits display modular architecture at different scales of organization. Such neural assemblies are typically associated to functional specialization that favours both the segregation and the integration of ...
Las enfermedades cardiovasculares (ECVs) son la principal causa de mortalidad en el mundo Occidental. El interés de prevenir y tratar las ECVs ha desencadenado un rápido desarrollo de los sistemas de adquisición de ...
L'acústica de sales s'encarrega de l'estudi del comportament de les ones sonores en espais tancats.La informació acústica de qualsevol entorn, coneguda com la resposta impulsional, pot ser expressada en termes del camp ...
Aquesta tesi doctoral proposa i avalua un enfocament computacional per a la descripció automàtica dels aspectes tonals de la música a partir de l'anàlisi de senyals d'-audio polifòniques. Aquests mètodes es centren en el ...
This dissertation revolves around the task of computational key estimation in electronic dance music, upon which we perform three interrelated operations. First, we attempt to detect possible misconceptions within the task, ...
Les tècniques d'imatge d'alt rang dinàmic (HDR) potencialment permeten la captura i l'emmagatzematge de tota la informació de llum en una escena. No obstant això, els dispositius comuns de visualització són limitats en ...
Emotions are a fundamental part of human life. They play a critical role in how we think, behave, and implicitly understand each other. However, although computing devices are increasingly consequential in our world, they ...
