En esta tesis se analizan tres mecanismos de subasta distintos, todos ellos bajo el supuesto de valoraciones privadas e independientes.<br/>El primer mecanismo que analizamos es una subasta de múltiples unidades en la que ...
3-Alquil-2-metoxipirazines en mostos i vins: determinació analítica i estudi de la influència d'alguns factors vitivinícoles
Les 3-alquil-2-metoxipirazines es troben en moltes plantes, entre les quals hi ha Vitis vinifera. Les més importants pel que fa a la seva presència i potencial influència en l'aroma del vi són la 3-isobutil-, la 3-sec-butil- ...
3-month Euribor expectations and uncertainty using option-implied probability densities
The evolution of market interest rates is a key component of the trans-mission of monetary policy. Central Banks, market participants and monetary policy practitioners make use of the information contained in financial ...
360° content made accessible: A user-centered study on audio description
Aquesta tesi explora com es pot implementar l’audiodescripció en vídeos de 360°, un dels nous formats audiovisuals que s’han introduït al mercat durant els últims anys. Els estudis de recepció, realitzats al llarg d’una ...
3d and/or 4f coordination compounds derived from chiral Schiff bases: magnetic and spectroscopic study
This PhD thesis has been developed in the Molecular Magnetism Group of the University of Barcelona. As its name indicates, the Molecular Magnetism Group is mostly interested in the magnetic study of coordination complexes, ...
3D audio technologies : applications to sound capture, post-production and listener perception
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 ...
3D FEM meso-level analysis of sulphate attack in concrete: new results and developments using parallel HP computing
(English) When concrete is subject to an environment characterised by a high humidity index and rich in sulphate ions, a concrete degradation process may be initiated due to External Sulphate Attack (ESA). The sulphate ...
3D in vitro models for neural progenitor cell differentiation and network formation
[eng] Conventional 2D in vitro and animal models have been found inadequate to fully uncover the intricate mechanisms happening in the brain and its diseases. Engineering-based models emerge as promising alternatives to ...
3D mapping and path planning from range data
This thesis reports research on mapping, terrain classification and path planning. These are classical problems in robotics, typically studied independently, and here we link such problems by framing them within a common ...
3D Motion Data aided Human Action Recognition and Pose Estimation
En aquest treball s’explora el reconeixement d’accions humanes i l'estimació de la seva postura en seqüències d'imatges. A diferència de les tècniques tradicionals d’aprenentatge a partir d’imatges 2D o vídeo amb la sortida ...
3D Partial scans models for people recognition with a RGB-D sensor
