  • Electronic & ionic conduction & correlated dielectric relaxations in molecular solids 

    Zachariah, Manesh (Universitat Politècnica de Catalunya, 2016-11-17)
    Tesi
    Accés obert
    The study of crystalline materials has played a prominent role in solid state physics, whose basic theories were formulated for crystalline matter. However, disordered materials are more abundant in nature than crystalline ...
  • Dynamic stochastic modeling for inertial sensors 

    Wis Gil, Mariano (Universitat Politècnica de Catalunya, 2016-11-02)
    Tesi
    Accés obert
    Es ampliamente conocido que los modelos de error para sensores inerciales tienen dos componentes: El primero es un componente determinista que normalmente es calibrado por el fabricante en el firmware de la IMU. El segundo ...
  • Dynamics of disordered systems 

    Vispa, Alessandro (Universitat Politècnica de Catalunya, 2016-11-24)
    Tesi
    Accés obert
    Disordered systems are ubiquitous in nature and their study is complicated and often leads to controversial results. In any case, the important role of such systems in science and technological applications should not be ...
  • Liquid crystals in woodpile photonic crystals : fabrication, numerical calculation and measurement 

    Ho, Chih-Hua (Universitat Politècnica de Catalunya, 2016-03-14)
    Tesi
    Accés obert
    Both experimental and numerical studies on Liquid Crystal (LC) infiltrated woodpile Photonic Crystal (PhC) are implemented in this thesis. The most well-known optical phenomenon of PhC is photonic bandgap (PBG). It is ...
  • Quantum chemistry and conformational sampling meet together : a powerful approach to study and design metalloprotein reactivity 

    Monza, Emanuele (Universitat Politècnica de Catalunya, 2016-12-19)
    Tesi
    Accés obert
    Metalloprotein are proteins containing metal ion cofactors. Compared to chemical catalysts, metalloproteins have a well-defined configuration around the active site which ensures higher specificity, selectivity and reaction ...
  • Dielectric spectroscopy studies of low-disorder and low-dimensional materials 

    Tripathi, Pragya (Universitat Politècnica de Catalunya, 2016-11-17)
    Tesi
    Accés obert
    In this thesis we employ dielectric spectroscopy (in different implementations) to study the dielectric properties of different materials ranging from completely disordered supercooled liquids to low-disorder solids with ...
  • Stochastic and complex dynamics in mesoscopic brain networks 

    Malagarriga i Guasch, Daniel (Universitat Politècnica de Catalunya, 2017-01-13)
    Tesi
    Accés obert
    The aim of this thesis is to deepen into the understanding of the mechanisms responsible for the generation of complex and stochastic dynamics, as well as emerging phenomena, in the human brain. We study typical features ...
  • High-order hybridizable discontinuous Galerkin method for viscous compressible flows 

    Javadzadeh Moghtader, Mostafa (Universitat Politècnica de Catalunya, 2016-11-04)
    Tesi
    Accés obert
    Computational Fluid Dynamics (CFD) is an essential tool for engineering design and analysis, especially in applications like aerospace, automotive and energy industries. Nowadays most commercial codes are based on Finite ...
  • Coupling and stochasticity in mesoscopic brain dynamics 

    Jedynak, Maciej (Universitat Politècnica de Catalunya, 2017-03-27)
    Tesi
    Accés obert
    The brain is known to operate under the constant influence of noise arising from a variety of sources. It also organises its activity into rhythms spanning multiple frequency bands. These rhythms originate from neuronal ...
  • Population synthesis studies of the white dwarfs of the galactic disk and halo 

    Cojocaru, Elena-Ruxandra (Universitat Politècnica de Catalunya, 2016-11-24)
    Tesi
    Accés obert
    As the evolutionary end-point of most main-sequence stars, white dwarfs can be used to infer important properties concerning the formation and evolution of the different Galactic stellar populations. Population synthesis ...
