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 ...
This thesis dissertation discusses the microstructure, thermal behavior, magnetic and mechanical properties of some Fe-based alloys and a high entropy alloy (HEA) in the form of mechanically alloyed powders or bulk solids, ...
Els aliatges magnètics amb memòria de forma es caracteritzen per presentar tant la transformació estructural austenita – martensita com la magnètica (ferromagnetisme – paramagnetisme). El conjunt de propietats els fa ...
One of the most important radiative properties of aerosols is their optical thickness (AOD), which is closely linked to the total burden of atmospheric aerosols. On the contrary, we do avail of long time series of sunshine ...
This work is framed in the general context of the synthesis and characterization of Mn or Ca based alloys, which are subsequently applied in degradation processes of azo dyes used in the textile industries. The alloys were ...
Shape memory alloys witch exhibit magnetically induced phase transformations at room temperatures are the most interesting for magnetic cooling applications. Heusler type alloys (both stoichiometric and non-stoichiometric) ...
Coastal zones are governed by physical forces originating from tidal currents, waves, winds and night convection, amongst others, and are characterized by the presence of canopy meadows. This thesis studies the hydrodynamic ...
This thesis investigates the impact response of novel laminates made with “thin-plies” as well as proposes a toughening method to improve their impact tolerance. To this purpose, we devised a wide experimental campaign ...
