The emergence of very capable mobile terminals, e.g. smartphones or tablets, has dramatically increased the demand of wireless data traffic in recent years. Current growth forecasts elucidate that wireless communication ...
Over the last few decades, transistor miniaturization has enabled a tremendous increase in the processing capability of commercial electronic devices, which, combined with the reduction of production costs, has tremendously ...
Current theories and mechanisms of nerve impulse propagation inside neurons do not give a satisfactory explanation to the nanoscale processes that occur inside the membrane. Propagation at the dendritic zones, and at the ...
Cache-coherent shared memory has traditionally been the favorite memory organization for chip multiprocessors thanks to its high programmability. In this organization the cache hierarchy is in charge of moving the data and ...
Aquesta tesi tracta la protecció de dades quan aquestes han de ser lliurades a usuaris en qui no es té absoluta confiança. En aquesta situació, les dades s'han de protegir de manera que segueixin essent utilitzables. Aquesta ...
(English) The properties of ultrathin materials present exciting opportunities to develop multifunctional surfaces. In addition, the use of plastic and thin glass as transparent substrates has the potential to extend the ...
The rapid evolution of the cruise industry in the last 50 years is evident. In the nineteenth century, cruise ships were simple modes of transport used by immigrants to travel on transoceanic voyages from Europe to North ...

El éxito clínico de los implantes dentales, fabricados en titanio comercialmente puro (Ti c.p.), está basado en la consecución de la osteointegración, es decir, la conexión directa estructural y funcional entre el hueso ...
Los tejidos de algodón se someten a procesos de preparación (desencolado, descrudado y blanqueo) basados en la eliminación de impurezas presentes en la superficie de la fibra. Actualmente se blanquean con peróxido de ...
En el capítulo 1 se presentan algunos conceptos básicos relacionados con el tráfico de voz, junto a los modelos más comúnmente utilizados en la evaluación y dimensionado de sistemas de telefonía móvil. En todos los casos ...
Medical applications of technical textiles are an expanding field of research. One of the added values of these new materials would be that they were suitable to contain and release active compounds in a controlled and ...
Automata are a widely used formalism in computer science as a concise representation for sets. They are interesting from a theoretical and practical point of view. This work is focused on automata that are executed on ...
The central concept of the present thesis is that the sense of belonging underlying heritage should be rooted in a strong community-based feeling. Sure enough, historical assets are looked at with a feeling of admiration ...
Different aspects of the bathyal ecosystem have been treated with the final aim to investigate trophic cascades driven by fishery (top-down control), a phenomenon that in bathyal systems has never been studied. This was ...
En esta Tesis Doctoral se ha analizado las relación de la comunidad ictioplanctonica con su ambiente físico y trófico en dos condiciones hidrográficas contrastadas (estratificación estival y mezcla otoñal) y se ha caracterizado ...
Landslides and debris flows falling into reservoirs, natural lakes, fjords or seas can generate impulsive waves, which can be assimilated to tsunamis. This phenomenon, also known as "landslide tsunami", can be highly ...
Bone is the most transplanted tissue after blood. As pointed out by the World Health Organization, musculoskeletal diseases can potentially rise as the fourth largest cause of disability within the next years. Unfortunately, ...
