  • Fluid flow queue models for fixed-mobile network evaluation 

    Bernal Escribano, Álvaro (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    A methodology for fast and accurate end-to-end KPI, like throughput and delay, estimation is proposed based on the service-centric traffic flow analysis and the fluid flow queuing model named CURSA-SQ. Mobile network ...
  • An analysis of word embedding spaces and regularities 

    Gijón Agudo, Manuel (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    Word embeddings are widely use in several applications due to their ability to capture semantic relationships between words as relations between vectors in high dimensional spaces. One of the main problems to obtain the ...
  • Cholesky-factorized sparse Kernel in support vector machines 

    Abdellatif, Alhasan (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    Support Vector Machine (SVM) is one of the most powerful machine learning algorithms due to its convex optimization formulation and handling non-linear classification. However, one of its main drawbacks is the long time ...
  • Regularization of the triple collision in the collinear three body problem 

    Gutiérrez Bisbal, Javier (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    This is a work about the collision of 3 celestial bodies which are aligned in a straight line, by following Newton's Gravitational Law. There is an introduction which shows the most important items of the general N-Body ...
  • Invariant curves for area preserving maps 

    Wang, Chanyan (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    This work aims to present tool of this approach is the so-called parameterization method, that produces a Newton-like iterative method to solve the invariance equation for an invariant torus, and the KAM theorem is a result ...
  • Combinatorial properties of convex polygons in point sets 

    Torra Clotet, Ferran (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    The Erdős-Szekeres theorem is a famous result in Discrete geometry that inspired a lot of research and motivated new problems. The theorem states that for every integer n ≥ 3 there is another integer N_0 such ...
  • A C0 interior penalty method for 4th order PDE's 

    Fojo Álvarez, Daniel (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    Fourth order Partial Differential Equations (PDE's) arise in many different physic's fields. As an example, the research group for Mathematical and Computational Modeling at UPC LaCàN is studying flexoelectricity, a very ...
  • Discrete duality principle in different random graph models 

    Lesgourgues, Thomas (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    For a given random graph, a connected component that contains a finite fraction of the entire graph's vertices is called giant. The study of these components started with the \ER model, where it has been proven that removing ...
  • First order logic of sparse hyper-graphs 

    Larrauri Borroto, Lázaro Alberto (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Restricted access - author's decision
    We give a generalization the results from Lynch on the convergence law for sparse random graphs to sparse random hypergraphs.
  • Modelling attentional biases in bistable perception 

    Vilardell Barnosell, Marina (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    Binocular rivalry is a type of bistable perception phenomena that arises when the eyes are unable to combine ambiguous stimuli into a unique image. It promotes a competition process between the visual interpretations ...
  • Phase response to stimuli : the case of excitable systems 

    Moreno González, Román (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Open Access
    In this thesis we extend the idea of Phase Resetting Function (PRF) to the case of excitable systems where there are no sustained oscillations. We use theoretical results to justify the definition of an asymptotic phase ...
  • An overview of Uniform Roe Algebras: Asymptotic Dimension and Real Rank 

    Vilalta Vila, Eduard (Universitat Politècnica de Catalunya, 2019-07)
    Master thesis
    Restricted access - author's decision
    The aim of this master thesis is to study the relation between the real rank of uniform Roe algebras and the asymptotic dimension of the space with which they are defined. As a consequence of some recent results on the ...
