This thesis covers the development of monotonicity preserving finite element methods for hyperbolic problems. In particular, scalar convection-diffusion and Euler equations are used as model problems for the discussion in ...
Two innovative radiotherapy (RT) approaches are under development at the ID17 Biomedical Beamline of the European Synchrotron Radiation Facility (ESRF): microbeam radiation therapy (MRT) and minibeam radiation therapy ...
The main objective of the thesis is to study static and/or dynamic properties of a set of quantum fluids by means of quantum Monte Carlo techniques, mainly using the path integral formalism to obtain results both at zero ...
Since white dwarfs are the final stage of the evolution of the vast majority of stars, they carry important information about the chemical evolution of our Galaxy, its star formation rate, and its structure and dynamics. ...
The Thesis is devoted to simulations of quantum phase transitions by means of Quantum Monte Carlo techniques. Quantum phase transition is a transition between phases at zero or low enough temperature, where quantum effects ...
The city morphology is the greater evidence of human habitation and intervention on the natural landscape aimed both at individual protection and community living. It is an intervention that modifies not only the landscape ...
Esta tesis investiga sobre el proceso de transformación de la forma arquitectónica, analizando una técnica específica denominada morphing. La técnica del morphing se utiliza en los gráficos por ordenador para la transformación ...
While marine, anthropogenic noise pollution is a scientific and societal matter of concern, there is limited knowledge on how sea animals, particularly cetaceans, perceive their environment through sounds. Toothed whales, ...
En esta tesis se estudia la formación y mantenimiento de los bancos de arena sobre la plataforma continental asociados a la costa. Estos son estructuras sedimentarias de forma alargada y que se repiten periódicamente a lo ...
The natural fibers that come from vegetable origin have become a potential and competitive option as a reinforcement composite based on cement. This is due to their high resistance and low cost features, and also their ...
Although silicon (Si) is used in most current commercial power semiconductor components, Si capabilities are insufficient for new energy conversion requirements. Some of its important limitations are related with power ...
Motion planning is a traditional field in robotics, but new problems are nevertheless incessantly appearing, due to continuous advances in the robot developments. In order to solve these new problems, as well as to improve ...
El objeto de este trabajo pasaba por obtener un motor con un alto par de arranque pero con intensidades limitadas, con variaciones de la intensidad en función de la carga prácticamente inapreciables aunque con pérdidas en ...
Esta tesis estudia las acciones que el gobierno francés llevo a cabo durante los años 60 para afrontar al turismo masivo de sol y playa. Estas acciones tuvieron como objetivo responder al desequilibrio económico del ...
La present memòria estudia l'estabilitat estructural de ternes de matrius. Es ben conegut que els sistemes dinàmic lineals amb coeficients constants poden venir definits per ternes de matrius, d'aquí l'interès d'aquest ...
As participants in today¿s society, where the most important resorce is knowledge, the researcher bent on making virtual experiences that contribute to the training of both students and teachers in knowledge management as ...
Interconnection networks represent the backbone of large-scale parallel systems. In order to build ultra-scale supercomputers larger interconnection networks are being designed and deployed. As compute nodes become more ...
Even today supercomputing systems have already reached millions of cores for a single machine, which are connected by using a complex network interconnection. Reducing communication time across processes becomes the most ...
Landslides and slope instabilities represent one of the most important problems in geotechnics causing significant damages around the world every year. Understanding the mechanics of the whole process is of particular ...
Les xarxes mòbils ad-hoc, també conegues com a MANETs, han estat des de fa ja molt temps objectiu d'estudi per part de la comunitat científica. No obstant això, la seva importància dins el món de la indústria és encara ...
