El Allaoui, Nazha (Data de defensa: 2016-07-21)
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 ...
Barcelona Arbat, Aina (Data de defensa: 2024-03-11)
Seagrass meadows are globally extensive nearshore ecosystems known as coastal engineers that provide key ecological services in coastal areas such as attenuating wave and turbulence and promoting sediment deposition. ...
Kanzaki Cabrera, Takeichi (Data de defensa: 2013-11-29)
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 ...
Sánchez Rodríguez, Daniel (Data de defensa: 2015-10-14)
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 ...
Rodríguez Amor, Daniel (Data de defensa: 2013-06-28)
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, ...
López de Rioja, Víctor (Data de defensa: 2019-03-11)
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 ...
Sánchez Martín, Xavier (Data de defensa: 2008-05-26)
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, ...
Deltell, Àlex (Data de defensa: 2020-09-07)
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 ...
Zaara, Kaouther (Data de defensa: 2023-11-03)
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, ...
Coll Riera, Rosa (Data de defensa: 2014-11-13)
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 ...
Sanchez Romero, Alejandro (Data de defensa: 2016-06-06)
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 ...
Ben Mbarek, Wael (Data de defensa: 2018-11-20)
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 ...
Wederni, Asma (Data de defensa: 2021-11-26)
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) ...
Pujol Company, M. Dolors (Data de defensa: 2013-04-16)
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 ...
García Rodríguez, Santiago (Data de defensa: 2019-06-28)
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 ...
