En los últimos años, el análisis numérico de problemas acoplados, como los procesos de degradación de materiales y estructuras relacionados con los efectos medioambientales, ha cobrado especial importancia en la comunidad ...
The main object of this Thesis is the study of the dynamical coupling between cellular processes, and how this coupling gives rise to a well-defined behavior in the presence of non-linearities and noise. Cell functioning ...
Unsaturated flow plays an important role in numerous environmental phenomena. It is complex in arid regions, where liquid water fluxes are small and vapor fluxes become relevant, so that heat, water and solute mass transport ...
The brain is known to operate under the constant influence of noise arising from a variety of sources. It also organises its activity into rhythms spanning multiple frequency bands. These rhythms originate from neuronal ...
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
Epistemological Framework. The present thesis provides a specific approach to the realm of Evolutionary Aesthetics, and is probably the first architectural research effort to take into account the recent achievements of ...
La tesis tiene por objetivo aportar nuevos conocimientos sobre la creatividad aplicada en la ingeniería, en concreto, en la fase de generación de nuevas ideas. Para ello se emplean cinco líneas de trabajo: (a) Dando un ...
In recent years, multi-threaded processors have become more and more popular in industry in order to increase the system aggregated performance and per-application performance, overcoming the limitations imposed by the ...
La Base de Datos Mundial de Áreas Protegidas (WDPA World Database on Protected Areas), cataloga 130.709 áreas que cubren 24,23 millones de km2 (WDPA 2012). Estos espacios cubren más del 12% de la superficie terrestre ...
Durante las últimas décadas se han realizado cambios profundos en los modelos de financiamiento rural en México y en el mundo. Los resultados en el desarrollo de mercados financieros muestran un panorama cada día más ...
La crioconcentració és una operació unitària relativament poc aplicada a la indústria alimentària.<br/>Consisteix en la separació de sòlids solubles d'una fase aquosa mitjançant la congelació de l'aigua.<br/>En primer lloc ...
El presente trabajo centra su estudio en la problemática de los efectos térmicos ambientales en puentes de hormigón. Los objetivos perseguidos en esta tesis son, por una parte, el desarrollo de un modelo analítico capaz ...
En esta tesis hemos querido básicamente considerar el diseño de funciones de coste para adaptación ciega en un amplio margen de aplicaciones en el ámbito de las comunicaciones digitales, tomando en consideración los ...
La finalidad de esta tesis es la obtención de las distribuciones de velocidades, presiones y temperaturas en la convección forzada de flujos compresibles en situaciones bidimensionales y de estabilización. Es a partir de ...
The thesis work started with the beginning of the freelance professional career. The subjects investigated throughout this work came up of the worries and questions during the project design and building process of real ...
O primeiro número da revista “Arquitectura” foi publicado em Janeiro de 1927. E embora com interrupções e alterações de orientação editorial, a revista publicou-se até 1984, em quatro séries. Nos primeiros 30 anos publicaram-se ...
This thesis provides a contribution to the field of Medium Access Control (MAC) layer protocol design for wireless networks by proposing and evaluating mechanisms that enhance different aspects of the network performance. ...
Scaling traditional telecommunication networks so that they are able to cope with the volume of future traffic demands and the stringent European Commission (EC) regulations on emissions would entail unaffordable investments. ...
Network planning and operation in core optical networks require processes that lead to a cost-effective network able to effectively accommodate the given traffic demands. Crosslayer techniques that exploit information ...
Large-scale simulation and visualization are essential topics in areas as different as sociology, physics, urbanism, training, entertainment among others. This kind of systems requires a vast computational power and memory ...
