The use of Fibre Reinforced Polymers (FRP) composites has grown in popularity over the last few decades. They offer outstanding mechanical properties combined with a low density, making them an excellent solution for many ...
This dissertation has as its goal the quantitative evaluation of the application of<br/>coupled hydrodynamic, ecological and clarity models, to address the deterministic prediction of water clarity in lakes and reservoirs. ...
High temperature superconductivity and in particular YBa2Cu3O7-x (YBCO) coated conductors (CCs) are a crucial technology for the drastic reduction of CO2 emissions. Since nowadays YBCO CCs are not competitive economically, ...
This work is focused on the production and characterization of: (1) Fe based nanocrystalline soft magnetic materials of NANOPERM and HITPERM families and (2) Heusler magnetic shape memory alloys. Within the first typology, ...
Adhesive bonds could replace more traditional mechanical joints, making structures lighter and smoother. Stresses are distributed over a larger area, and dissimilar materials can be bonded, accommodating differences in ...
Aquí hem aplicat el Princeton Ocean Model als embassaments de Sau i Boadella, situats a Catalunya, Espanya. Les simulacions s'han realitzat a l'estació d'estiu, quan la columna d'aigua està estratificada de forma contínua, ...
Applicaciò d'un model de hydrodinàmica i de qualitat de l'aigua als embassaments de Sau i Boadella
Atmospheric downwelling longwave radiation is an important component of the terrestrial energy budget; since it is strongly related with the greenhouse effect, it remarkably affects the climate. In this study, I evaluate ...
Procesos hidrodinámicos determinan, en un alto grado la calidad del agua en embalse, sin embargo dichos procesos han sido tradicionalmente olvidados en la gestión de embalse. En esta tesis se presentan evidencias de los ...
Aerosols and clouds, as two particular cases of a single phenomenon (i.e., a suspension of particles in the air), are important components in the climate system. They play a crucial role in determination of Earth’s energy ...
To overcome the challenges coming from environmental impacts has been a priority for the aeronautical sector in the past years, with a special focus on reducing CO2 emissions. The fibre-reinforced polymers (FRP) are ...
The threat of impact on laminated composite structures has been a serious concern in the aerospace industry and scientific community because the compression load-carrying capacity of the structures, namely Compression 1/2 After ...
L'objectiu general d'aquest treball és l'obtenció de nous materials nanoestructurats magnètics tous produïts mitjançant la tècnica de l'aliatge mecànic. Forma part d'un projecte més ampli de desenvolupament d'aquests tipus ...
This thesis deals with the production, characterization and analysis of Fe and Co based nanocrystalline and amorphous soft-ferromagnetic alloys, alloys showing ferromagnetic hysteresis cycles with low energy losses, produced ...
S'estudia la resposta de la capa de barreja oceànica al forçament atmosfèric considerant dades obtingudes durant 12 dies d'abril del 2001 a 42 estacions a través de l'Atlàntic nord seguint aproximadament la latitud de ...
In the margins of continents there are the coastal zones, regions of remarkable biological productivity. Coastal zones include, among others, wetlands, that are land areas inundated permanently o seasonally, characterized ...
Las nubes constituyen uno de los fenómenos más importantes en cuanto a la regulación de la radiación entrante y saliente de la Tierra y por ende, del clima. El principal objetivo de esta tesis es analizar cómo se reproduce ...
This thesis presents population dynamics models that can be applied to predict the rate of spread of the Neolithic transition (change from hunter-gathering to farming economics) across the European continent, which took ...
Improving methods for automatic and continuous description of cloud has a huge importance in order to determine the role of clouds in climate and their contribution to climate change. The geometric characteristics of clouds, ...
Transport industry, especially automotive, is one of the most pollutant in the world. Current environmental concerns demand original equipment manufacturers (OEM’s) to reduce the amount of emissions released by their ...
