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 ...
Aquesta Tesi Doctoral se centra en el disseny d'un nou linealitzador de Predistorsió Digital (Digital Predistortion - DPD) capaç de compensar la dinàmica i els efectes no lineals introduïts pels Amplificadors de Potència ...
(English) In the wake of a digital revolution, contemporary society finds itself entrenched in an era where network applications' demands surpass the capabilities of conventional network management solutions. This dissertation ...
Medical imaging refers to several different technologies that are used to view the human body in order to diagnose, monitor, or treat medical conditions. Each type of technology gives different information about the area ...
In recent years there has been an extraordinary growth of large-scale data processing and related technologies in both, industry and academic communities. This trend is mostly driven by the need to explore the increasingly ...
Water is a limited resource essential for life. Human activities have been exercising considerable pressures on it. The unsustainable use and the need to improve the management of water are among the largest global concerns ...
Classical nova explosions are stellar explosions that take place in close binary systems with an energy release only exceeded by gamma-ray bursts and supernova explosions. Matter from the white dwarf flows through the inner ...
Thin film photovoltaics encompass a group of technologies able to harvest light within a few microns thickness. The reduced thickness allows a low cost of manufacture while making the films flexible and adaptable to ...
This thesis is devoted to design a multi-layer MPC controller applied to the complex water network taking into account that the different layers with different time scales and control objectives have their own controller. ...
