Pérez Losada, Joaquim (Date of defense: 2001-11-15)
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. ...
Figueroa Rodríguez, Jesús Manuel (Date of defense: 2005-11-24)
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 ...
González Gasch, Àlex (Date of defense: 2006-04-07)
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 ...
Vidal Hurtado, Javier (Date of defense: 2007-04-27)
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 ...
Sánchez Martín, Xavier (Date of defense: 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, ...
Forcat Torras, Francesc (Date of defense: 2009-07-28)
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, ...
Viúdez i Mora, Antoni (Date of defense: 2011-04-15)
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 ...
Takkouk, Saddek (Date of defense: 2011-05-06)
Applicaciò d'un model de hydrodinàmica i de qualitat de l'aigua als embassaments de Sau i Boadella
Isern Sardó, Neus (Date of defense: 2011-12-01)
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 ...
Pujol Company, M. Dolors (Date of defense: 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 ...
Rodríguez Amor, Daniel (Date of defense: 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, ...
Kanzaki Cabrera, Takeichi (Date of defense: 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 ...
Costa Surós, Montse (Date of defense: 2014-10-02)
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, ...
Coll Riera, Rosa (Date of defense: 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 ...
Planella Morató, Jesús (Date of defense: 2015-07-15)
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 ...
Sánchez Rodríguez, Daniel (Date of defense: 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 ...
Sanchez Romero, Alejandro (Date of defense: 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 ...
Enríquez Alonso, Aarón (Date of defense: 2016-07-01)
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 ...
El Allaoui, Nazha (Date of defense: 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 ...
