  • Variational mechanics and numerical methods for structural analysis 

    Andújar, Rabindranath (Universitat Politècnica de Catalunya, 2012-06-25)
    Master thesis
    Open Access
    This work focuses on the particular application of the variational principles of Lagrange and Hamilton for structural analysis. Different numerical methods are compared in their computation of the elastic energy through ...
  • Structural study of C2Cl6 by molecular dynamics 

    Henao Aristizábal, Andrés (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: A Molecular Dynamics study of hexachloroethane C2Cl6 was done in order to study the structure at different temperatures, varying from 300K to 480K. The system at 480K showed a liquid phase, as reported in the ...
  • Smoothed Particle Hydrodynamics simulations of white dwarf close encounters in dense stellar systems 

    Aznar Siguan, Gabriela (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: In old dense stellar systems collisions of white dwarfs are a rather frequent phenomenon. Here we present the results of several Smoothed Particle Hydrodynamics simulations of close encounters of white dwarfs to ...
  • Multivariate Curve Resolution applied to Ion Mobility Spectra 

    Oller Moreno, Sergio (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: In this work, a Multivariate Curve Resolution (MCR) with Alternating Least Squares (ALS) method is described and used to identify the concentrations of a two-component (ethanol and acetone) mixture analysed with ...
  • Maximum Likelihood Approach for Stochastic Volatility Models 

    Camprodon Masnou, Jordi (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: Volatility is a measure of the amplitude of price return fluctuations. Despite it is one of the most important quantities in finance, volatility is a hidden quantity because it is not directly observable. Here we ...
  • Swimmers’ Collective Dynamics Modelization 

    Ferré Porta, Guillem (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: We describe a new model in order to study the properties of collections of self-propelled particles swimming in a two-dimensional fluid. Our model consist in two types of particles, the first interacting with each ...
  • Statistical Complex Analysis of Taxi Mobility in San Francisco 

    Sagarra Pascual, Oleguer (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: The recent developments in technology of movement tracking devices such as Global Positioning (GPS), together with the increasing availability of consistent data bases, have lately given rise to the study of human ...
  • Global epidemic spreading processes in coupled networks 

    Saumell Mendiola, Anna (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: We study the effect of coupling two random networks where an epidemic process propagates. A theoretical SIS model is applied and a new critical threshold for the existence of an endemic state is analytically ...
  • Characterization of the clustering phase transition of a complex network embedded in a hyperbolic plane 

    Colomer de Simón, Pol (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: If we distribute nodes homogeneously in an hyperbolic plane and connect each possible pair of nodes with a probability that depends on the hyperbolic distance among them, heterogeneous degree distributions and ...
  • Infinite period bifurcation due to imperfections in rotating thermal convection 

    López Alonso, Jose Manuel (Universitat Politècnica de Catalunya, 2011-06-17)
    Master thesis
    Open Access
    A pinning area is a band of finite width where rotating waves with precession frequences near zero turn into steady non-axisymmetric solutions. Dynamical systems theory suggests that any imperfection breaking the SO(2) ...
