Nowadays, thanks to the increase of computers capability to solve huge and complex problems, and also thanks to the endless effort of the geotechnical community to define better and more sophisticated constitutive models, ...
Els éssers vius es divideixen filogenèticament en eucarionts, amb un nucli ben definit, i bacteris. Hi ha dos tipus de bacteris, els eubacteris i els arqueobacteris. Els arqueobacteris tenen, entre altres diferències, una ...
The importance for the good management of the waste increases day by day, due to the increase of the generation of waste .Composting is one of the most used treatments in the management of the organic fraction of municipal ...
Aquesta tesi tracta sobre amplificació de potència d'alt rendiment de senyals variables en el temps; concretament, tracta sobre conversió de potència eficient (amb mínimes pèrdues) de tensions DC continues en senyals de ...
El análisis se ha desarrollado tomando en consideración un conjunto de producciones arquitectónicas, a las que se añade el examen de las posturas teóricas sostenidas por los mismos arquitectos, a través de ensayos, artículos, ...
The thesis "Barcelona in the spotlight. Readings of the city" propases an overview of the city derived from the process of architectural design. lt propases to decipher the concept of a city which exists implicitly in the ...
The use of the subsoil in our cities was limited until more or less a century ago. The technological advances of the twentieth century and the increased need for greater urban comfort has led to intensive building in all ...
Current refrigeration devices, based on vapour-compression cycles, employ refrigerants such as HFCs, which exhibit a global warming potential a thousand times higher than the one produced by CO2,. Furthermore, the increasing ...
The following research originates in the need to enhance the Generic Skills in the profile of graduate Engineers according to the needs of our current Society of Knowledge, considering that Engineering Education has not ...
En esta tesis se desarrolla, siempre con el enfoque bayesiano en mente, una metodología estadística para el análisis de datos discretos en su aplicación en problemas estilometría. El análisis estadístico del estilo literario ...
Aquesta tesi gira al voltant del disseny de receptors per a sistemes globals de navegació per satèl·lit (Global Navigation Satellite Systems, GNSS). El terme GNSS fa referència a tots aquells sistemes de navegació basats ...
The predictability of beach inundation is mainly related to wave runup and most of the formulations that have been developed focus on the hydrodynamics, disregarding the morphological changes caused during storms. For these ...
In order to provide wireless services for the current demand of high data rate mobile applications, more spectrally efficient systems are needed. As a matter of fact, the current wireless systems are limited by a frequency ...
SLAM (Simulatenous Localization and Mapping) es quizá el problema más importante a solucionar en robótica para construir robots móviles verdaderamente autónomos. El SLAM es acerca de cómo un robot móvil opera en un entorno ...
This Thesis conducts the study of bedform development and dynamics in the inner shelf integrating observations at different spatial and temporal scales. An initial assumption is that different scales of sedimentary processes ...
In this thesis, the interaction between flow and sediment in alluvial channels is studied from an empirical approach, for conditions close or pertaining to supercritical flow, and for four types of sediment: sand, gravel ...
The technological era that we live in is sometimes described as the Information Age. Colossal amounts of data are generated every day and considerable effort is put into creating technologies to process, store and transmit ...
The main aim of this thesis is the study of the Bernstein-Sato polynomial of plane curve singularities. In this context, we prove a conjecture posed by Yano about the generic b-exponents of a plane irreducible curve. In ...
A new thin shell finite element is presented. This new element doesn’ t have rotational degrees of freedom. Instead, in order to overcome the C1 continuity requirement across elements, the author resorts to enhance the ...
