In recent years, multiresolution models have progressed substantially. At the beginning, discrete models were employed in graphics applications, due mainly to the low degree of complexity involved in implementing them, ...
El sentido filosófico del término ontología hace referencia a la esencia misma del ser, a su existencia (onto=ser). Para un sistema inteligente lo que existe es lo que puede representarse. En informática una ontología se ...
This thesis approaches the study of several machine learning techniques to improve the performance of indoor positioning systems, with a special focus on wearable and low-cost devices. It also presents some tools designed ...
This thesis is an invitation to rethink how simplistic approaches to biosignal processing enrich the potential of personal sensing in line with the fast development of what have come to be undeniably ubiquitous technologies. ...
Las arquitecturas destinadas a computación de altas prestaciones (HPC) basadas en aceleradores gráficos (GPUs) se han convertido en los últimos años en una alternativa extendida que combina altas prestaciones y un bajo ...
El cloud-bursting (despliegue de nube híbrida que complementa temporalmente máquinas virtuales locales con máquinas vituales remotas) ha experimentado una rápida adopción entre los usuarios de análisis de big data. Sin ...
This thesis addresses the need for reliable and immersive human-robot interfaces in hazardous environments. Three key goals were achieved. Firstly, techniques were developed to provide immersive interactions while ensuring ...
The main motivation behind this thesis is the problem of aspect-based sentiment summarization and its application to Business Intelligence (BI). Given a collection of opinion posts, aspect-based summarization has to do ...
The Large Hadron Collider (LHC) is generating Physics data at an unprecedented rate that is expected to continue increasing in the future. This situation results in increasing demands in computation and processing power ...
This dissertation targets two important problems. The first one is the design of low-level DLA kernels for architectures comprising two (or more) classes of cores. The main question we have to address here is how to attain ...
La distribución no balanceada de los datos entre las clases, así como la presencia de ruido y el traslape de clases, son complejidades de los datos que a menudo interfieren en el rendimiento de clasificadores. Para afrontar ...
Este trabajo de tesis doctoral se centra en el uso de ontologías de dominio y su refinamiento enfocado a la recuperación de la información. El dominio seleccionado ha sido el de la Biomedicina, que dispone de una extensa ...
Robots must successfully execute tasks in the presence of uncertainty. <br/>The main sources of uncertainty are modeling, sensing, and control. Fine motion problems involve a small-scale space and contact between ...
En esta tesis doctoral se aborda la solución de sistemas dispersos de ecuaciones lineales utilizando métodos iterativos precondicionados basados en subespacios de Krylov. En concreto, se centra en ILUPACK, una biblioteca ...
The video games, simulators and virtual reality industry increasingly demands more complex and realistic natural environments, which makes manual generation difficult. To solve it, procedural techniques have been developed, ...
La interoperabilitat és la capacitat de les empreses per a col·laborar de manera eficient, preservant la seua pròpia identitat i la seua pròpia manera de fer negocis. Para abastar aquest objectiu les empreses necessiten ...
<p>The automatic extraction of knowledge from the world by a robotic system as human beings interpret their environment through their senses is still an unsolved task in Artificial Intelligence. A robotic agent is in contact ...
From the end of 80's there has been a great interest in the study of qualitative models to represent and to reason with spatial aspects. The present work is centred in the development and application of a model to reason ...
Se presenta un sistema capaz de coordinar una pinza de dedos plano-paralelos y un sistema de visión con el objetivo de determinar puntos de agarre bajo condiciones de estabilidad.<br/>La elección de puntos de agarre se ...
This thesis mainly deals with the stages of model description and evaluation of Indoor Positioning Systems based on fingerprinting. Its first contribution is a meta-review that addresses the current state of the art and ...
