  • Local ordering and dynamics of plastic crystals 

    Henao Aristizábal, Andrés (Universitat Politècnica de Catalunya, 2016-09-23)
    Tesi
    Accés obert
    Many materials of scientific interest show a disordered phase, with their molecules presenting positional disorder, orientational disorder or both. Processes of interest to life also occur in these kind of phases as it is ...
  • Consolidation and assessment of a technique to provide fast and precise point positioning (Fast-PPP) 

    Rovira Garcia, Adrià (Universitat Politècnica de Catalunya, 2016-01-21)
    Tesi
    Accés obert
    The research of this paper-based dissertation is focused on the Fast Precise Point Positioning (Fast-PPP) technique. The novelty relies on using an accurate ionosphere model, in combination with the standard precise satellite ...
  • Guest-molecule dynamics and conductivity effects in carbon-based molecular solids 

    Mitsari, Efstratia (Universitat Politècnica de Catalunya, 2016-07-28)
    Tesi
    Accés obert
    Disordered systems are abundant in everyday life and so their study is of importance from a scientific and a technological point of view. The most common non-crystalline solid phases are structural glasses (e.g. window ...
  • Computer simulation of an excess proton in aqueous systems 

    Tahat, Amani Naser (Universitat Politècnica de Catalunya, 2016-06-01)
    Tesi
    Accés obert
    This thesis aims at studying the microscopic physical-chemical properties of an excess proton in aqueous systems. From bulk water environments to narrow hydrophobic channels constructed with a double-layered graphene slab, ...
  • Spatiotemporal coordination of collective activity in neuronal ensembles 

    Barardi, Alessandro (Universitat Politècnica de Catalunya, 2016-06-03)
    Tesi
    Accés obert
    The brain is a complex multiscale dynamical system made of neurons, connected with each other by synapses. Neurons are multidimensional nonlinear systems able to exhibit dynamical activities at different temporal and spatial ...
  • Design of the BELEN detector for wide energy range with flat and high detection efficiency 

    Riego Pérez, Albert (Universitat Politècnica de Catalunya, 2016-05-30)
    Tesi
    Accés obert
    The main objective of this work is to design the BEta-deLayEd Neutron detector (BELEN) detector for FAIR (Facility for Antiproton Ion Research). The purpose of this detector is the measurement of neutron emission probabilities ...
  • Observation and interpretation of type IIB supernova explosions 

    Morales Garoffolo, Antonia (Universitat Politècnica de Catalunya, 2016-03-08)
    Tesi
    Accés obert
    Core-collapse supernovae (CC-SNe) explosions represent the final demise of massive stars. Among the various types, there is a group of relatively infrequent CC-SNe termed type IIb, which appear to be hybrids between normal ...
  • Development of AINA code for the study of loss of plasma control events in ITER and DEMO, and contribution to the systems study of DEMO 

    Rivas Reguera, José Carlos (Universitat Politècnica de Catalunya, 2016-01-01)
    Tesi
    Accés obert
    Magnetic fusion is a long term, worldwide research activity. Plans are increasingly ambitious, cooperation is progressing, and goals seem to be closer every year. ITER reactor is being built, and several conceptual studies ...
  • Thermal diagnostics experiments for LISA Pathfinder 

    Gibert Gutiérrez, Ferran (Universitat Politècnica de Catalunya, 2016-02-23)
    Tesi
    Accés obert
    The LISA Pathfinder project is an ESA/NASA technology demonstrator mission that must test the critical instrumentation required for a future space-borne gravitational wave observatory based on the LISA design. The satellite, ...
  • Effects of vibrations applied to fluids at different gravity levels 

    Garcia Sabaté, Anna (Universitat Politècnica de Catalunya, 2016-06-20)
    Tesi
    Accés obert
    Due to the increasing interest in space exploration, management of two-phase flows in the absence of gravity has become a key aspect in improving the efficiency of technological applications for space missions. Understanding ...
