La llegada del sonido 3D está imponiendo cambios en varias etapas del flujo de trabajo, desde los sistemas de captación hasta las metodologías de postproducción y las configuraciones de altavoces. Esta tesis trata varios ...
This thesis has been accomplished in Crisalix in collaboration with the Universitat Pompeu Fabra within the program of Doctorats Industrials. Crisalix has the mission of enhancing the communication between professionals ...
In this thesis a method was developed to reconstruct both the 3D shape and the BMD distribution of bone structures from Dual-energy X-ray Absorptiometry (DXA) images. The method incorporates a statistical model built from ...
Osteoporosis is the most common bone disease, with a significant morbidity and mortality caused by the increase of bone fragility and susceptibility to fracture. Dual Energy X-ray Absorptiometry (DXA) is the gold standard ...
In recent years, zero-knowledge proofs have come to play a crucial role in distributed systems where there is no trust between the parties involved. Most popular proof systems are for the NP-complete language of arithmetic ...
Aquesta dissertació tracta del ritme musical. Més exactamente, tracta de programes informàtics que extreuen automàticament descripcions rítmiques a partir de senyals musicals d'àudio.<br/>Presentem nous algorismes per a ...
This dissertation proposes a computational data-driven methodology to measure music ensemble interdependence - the degree to which musicians interact and influence each other’s actions in order to achieve a shared goal - ...
In IEEE 802.11 WLANs, Link Adaptation mechanisms, which choose the transmission rate of each node, provoke unexpected and random variations on the effective channel capacity. When these changes are towards lower bitrates, ...
En los últimos años, las redes peer-to-peer (P2P) ha experimentado una fuerte expansión. Estos sustratos se constituyen en forma de redes overlay o de recubrimiento que interconectan usuarios de manera lógica y desacoplada ...
Representation learning is the field of modern machine learning focused on automatically producing useful representations from data. This thesis studies the impact of data volumes, annotation perspectives, and structural ...
In the last few years Wireless Sensor Networks (WSNs) have become an interesting field of research mainly due to the challenges and constraints of their design and the broad range of potential applications they can provide. ...
Through advances in sensor, networking, semiconductor and energy storage technologies, Wireless Sensor Networks (WSNs) are increasingly being deployed in many important applications to enable users to access information ...
Un dels principals requeriments de la gestió de drets digitals a la Web és un llenguatge compartit per a la representació del copyright. Les aproximacions actuals es basen en solucions purament sintàctiques, simples i ...
This thesis is centered on the construction of a cardiac atlas to serve as a common reference frame in the Virtual Physiological Human (VPH). The construction covers the entire construction pipeline, starting from a set ...
La comparación de imágenes es un ingrediente fundamental en muchos problemas de procesamiento de imagen y visión por computador. Esta tesis aborda el problema de la comparación de entornos locales en imágenes, o patches, ...
La arquitectura semántica diseñada ha sido probada dentro del entorno de la gestión de los derechos de la propiedad intelectual. Esta permite asimilar nuevos módulos y cambios en la estructura. Se ha diseñado específicamente ...
In this thesis, we make theoretical and practical contributions to the design of succinct arguments with universal setups in the pairing-based setting. We first introduce a new primitive, Checkable Subspace Sampling (CSS) ...
Recommender Systems represent a key instrument to convey consumption of contents available on the Web. They enhance the engagement among the users and the online platforms through algorithmic personalization. Injecting ...
The fast-growing adoption of technologies based on Machine Learning (ML), in addition to the large scale at which they operate, makes them a potential source of systematic discrimination against disadvantaged social ...
Aquesta tesi tracta d'algoritmes i fenòmens complexos en xarxes.<br/><br/>En la primera part s'estudia un model de neurones estocàstiques inter-comunicades mitjançant potencials d'acció. Proposem una tècnica de modelització ...
