Free-space optical (FSO) communications is drawing increasing attention as a promising technology to overcome bandwidth shortage, of an evermore crowded wireless marketplace. Currently radio-frequency (RF) technology ...
Ara que es comença a treure l’entrellat -o si més no a tenir una nova perspectiva- de la diversitat de microorganismes present als oceans gràcies a la biologia molecular i a la metagenòmica, el següent pas és esbrinar ...
Assembling original documents, historical material, completed or unrealized projects and the evolution of governmental and professional structures, this dissertation explores the development and construction of urban ...
This thesis proposes a new numerical technique: the eXtended Hybridizable Discontinuous Galerkin (X-HDG) Method, to efficiently solve problems including moving boundaries and interfaces. It aims to outperform available ...
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 ...
With the increased number of cores on a single processor chip, an application can achieve good performance if it splits the execution into multiple threads that run on multiple cores at the same time. To synchronize threads, ...
In this work we use geometric techniques in order to study certain natural extensions of free groups, and solve several algorithmic problems on them. To this end, we consider the family of free-abelian times free groups ...
L’educació va ser marcada a l’any 2000 per les Nacions Unides com un dels Objectius del Mil·lenni pel desenvolupament. Amb aquest objectiu, també conegut com “educació per a tothom”, es pretén que per l’any 2015, tots els ...
Technology has played a role of primary importance in humanity, therefore observing its effects in the field of higher education results very important. This research firstly aims to identify the differences over the digital ...
Soft errors caused by transient bit flips have the potential to significantly impactan applicalion's behavior. This has motivated the design of an array of techniques to detect, isolate, and correct soft errors using ...
The centrality of knowledge-based industries (KBI) in the economy of metropolitan areas leads to the transformation of their labour markets and promotion of new forms of urban growth. This is due, among other things, to ...
Se han obtenido y caracterizado una serie de poli(a-n-alquil g-glutamato)s (PAAG-n) con n³12 y de poli(a-n-alquil b,L-aspartato)s (PAALA-n), mediante transesterificación con n-alcoholes y se ha estudiado la influencia que ...
Ésta investigación tuvo como campo de estudio 60 medianas empresas tabasqueñas incorporadas al Sistema de Información Empresarial Mexicano, con la finalidad de conocer si éstas realizan acciones que les permitan generar ...
Hot-wire chemical vapour deposition (HWCVD) is a promising technique that permits polycrystalline silicon films with grain size of nanometers to be obtained at high deposition rates and low substrate temperatures. This ...
Face recognition (FR) has been extensively studied, due to both scientific fundamental challenges and current and potential applications where human identification is needed. FR systems have the benefits of their non ...
For the last decades, and especially in last years, light facades have been the greatest exponent of technology and innovation in construction. While they have played the leading role in several conventional buildings, ...
The ventilated facade is a multi-layer element that has been used in Europe for several decades. It has high degree of industrialization and specialization of elements. This "skin" of the building has evolved considerably ...
In this dissertation, we present a factoid question answering system, specifically tailored for Question Answering (QA) on spoken documents. This work explores, for the first time, which techniques can be robustly adapted ...
La present investigació doctoral es basa en l'estudi de les condicions de seguretat i de salut deis treballadors de la planta de prefabricats de dovelles de I'UTE L9. Per realitzar-la s'han tingut en compte d'una banda, ...
