    Temporal evolution of MHD waves in solar coronal arcades 

    Rial Lesaga, Samuel (Date of defense: 2019-10-11)

    [eng] In this thesis we will study vertical oscillations in a potential arcade under the approximation of a zero- plasma, when di erent density pro les are considered. On one hand we will focus on the time-dependent ...

    Test estructural i predictiu per a circuits RF CMOS 

    Suenaga Portuguès, Kay (Date of defense: 2008-12-17)

    En aquesta tesi s'ha desenvolupat una tècnica de test que permet testar un LNA i un mesclador, situats en el capçal RF d'un receptor CMOS, en una configuració de test semblant al mode normal de funcionament.<br/>La circuiteria ...

    Theoretical issues in Numerical Relativity simulations 

    Alic, Daniela Delia (Date of defense: 2009-09-18)

    In this thesis we address several analytical and numerical problems related with the general relativistic study of black hole space-times and boson stars. <br/>We have developed a new centered finite volume method based ...

    Time and Spatial Damping of Magnetohydrodynamic Waves in Partially Ionised Prominence Plasmas 

    Forteza Ferrer, Pep (Date of defense: 2013-02-11)

    Inici de l’estudi de l’efecte de les col•lisions entre ions i neutres en l’esmorteïment d’ones magnetohidrodinàmiques. Es considera un plasma parcialment ionitzat, infinit i homogeni, i s’analitza l’esmorteïment temporal ...

    Towards a gauge polyvalent numerical relativity code: numerical methods, boundary conditions and di erent formulations 

    Bona Casas, Carles (Date of defense: 2011-04-08)

    La present tesi doctoral versa sobre la resolucio numèrica de les equacions d'Einstein de la Teoria de la Relativitat. Es presenta: una nova familia de mètodes computacionals amb variació total acotada i d'implementació ...

    Two satellite-based rainfall algorithms, calibration methods and post-processing corrections applied to Mediterranean flood cases 

    de Luque Söllheim, Ángel Luis (Date of defense: 2008-03-14)

    Esta tesis explora la precisión de dos métodos de estimación de precipitación, Auto-Estimator y CRR (Convective Rainfall Rate), generados a partir de imágenes infrarrojas y visibles del Meteosat. Ambos métodos junto con ...

    Waveform modelling of binary black holes in the advanced ligo era 

    García Quirós, Cecilio (Date of defense: 2020-07-22)

    [eng] The focus of this thesis is the development of accurate and computationally efficient waveform models for the description of the signal of non-precessing and precessing blackhole binary systems detected by the ...
