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 ...
Turbulence intermittency influences so many processes in natural waters on a wide range of scales. This work analyzes intermittency, both internal and external, by considering two cases: the thermocline of a small lake ...
The general objective of this doctoral thesis has been to contribute to understand the modification of hydrodynamics in fragmented canopies. The effect of different parameters such as the canopy density, the plant height ...
Granular materials are multi-particle systems involved in many industrial process and everyday life. The mechanical behavior of granular media such as sand, coffee beans, planetary rings and powders are current challenging ...
L'objectiu d'aquest treball és analitzar mètodes químics de baix cost com a ruta per a sintetitzar òxids avançats a baixa temperatura. En particular, hem explorat l'SHS per a la síntesi d'un òxid catalitzador fent servir ...
Physical and mathematical models are extremely useful to understand key processes in population and evolutionary dynamics. Such models allow the study of many diverse features in spatial systems such as front propagation, ...
The thesis studies from an analytical and computational perspective, and by using reaction-diffusion equations, the spatiotemporal evolution of different populations. First, the dynamics of the T7 bacteriophage infecting ...
En aquesta tesi s'aborda l'estudi de la turbulència convectiva, a partir d'un treball experimental realitzat a l'estany de Banyoles. Més concretament, els objectius s'emmarquen en dues categories diferents. En la primera, ...
Magnetic memory alloys are a subset of shape memory materials that respond to the application of external magnetic fields. These materials are currently gaining more and more interest, given their properties, for use in ...
