    Gabaldón Casasayas, Jesús Enric (Date of defense: 2001-02-02)

    Es tracta d'una tesi fonamentalment interdisciplinària que aborda l'anàlisi de la dinàmica fitoplanctònica, en condicions de mar obert i en termes de fixació de carboni, en funció de pressos estrictament físics com són la ...

    Convección natural en cavidades tridimensionales 

    Sánchez Casals, Odalys (Date of defense: 2015-11-10)

    The modelling of convective transport processes involving heat and mass transfer in an incompressible Newtonian fluid in cylindrical domains is a relevant research subject both for theoretical research and for industry. ...

    Dynamics of metallic glasses explored by mechanical relaxation 

    Liu, Chaoren (Date of defense: 2015-10-07)

    Dynamic mechanical analysis (DMA) is often used to explore the relaxation dynamics of metallic glasses (MGs). Secondary relaxations in metallic glasses appear as an excess wing, as a shoulder of the primary relaxation peak ...

    Inestabilidades térmicas e hidrodinámicas ligadas a rupturas de simetría en cavidades anulares 

    Pino González, David (Date of defense: 2001-02-12)

    En esta tesis se estudia, mediante simulación numérica directa de las ecuaciones de Navier-Stokes, la dinámica de un fluido en el interior de un anillo cilíndrico en rotación con las tapas ligeramente inclinadas y sometido ...

    Microscopic description of two dimensional dipolar quantum gases 

    Macía Rey, Adrián (Date of defense: 2015-02-13)

    A microscopic description of the many-body properties of anisotropic homogeneous gases of bosonic dipoles in two dimensions is presented and discussed. By changing the polarization angle with respect to the plane, we study ...

    En este trabajo abordan diversos problemas relacionados con los flujos de fluido en régimen turbulento. El principal problema tratado es el de la dispersión de partículas en tiempos intermedios. Se analizan también las ...

    Time-varying networks approach to social dynamics : from individual to collective behavior 

    Starnini, Michele (Date of defense: 2014-10-24)

    The data revolution experienced by social science has revealed complex patterns of interactions in human dynamics, such as the heterogeneity and burstiness of social contacts. The recently uncovered temporal dimension of ...

    Variational mechanics and stochastic methods applied to structural design 

    Andujar Moreno, Rabindranath (Date of defense: 2015-02-03)

    This thesis explores a very well understood area of physics: computational structural dynamics. The aim is to stretch its boundaries by merging it with another very well established discipline such as structural design and ...
