  • Hopf and Neimark-Sacker bifurcations: applications to discrete-time hypercycles with functional shifts 

    Perona García, Júlia (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Open Access
    Hypercycles are cyclic catalytic sets of replicating macromolecules, where each one of the species catalyzes the replication of the next species of the set. This system has been widely studied within the framework of origins ...
  • Efficient deep ensembles by averaging neural networks in parameter space 

    Norris Mitchell, Philip (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Open Access
    Although deep ensembles provide large accuracy boosts relative to individual models, their use is not widespread in environments in which computational constraints are limited, as deep ensembles require storing M models ...
  • Automated valuation models 

    Arnalot Farràs, Joan (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Restricted access - confidentiality agreement
    This work is an introduction to AVM (automated valuation models), the different models to predict automatically the value of a property (and give a bound of the error). This work aims to show the different options of ...
  • Study of perturbations of an oscillating neuronal network via phase-amplitude response functions 

    Arqué Pérez, Ferran (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Open Access
    Phase reduction is a powerful tool for understanding the behavior of perturbed oscillators. It allows for the description of high-dimensional oscillatory systems in terms of a single variable, the phase. Alternatively, ...
  • Urban wind turbine farm optimization using genetic algorithm 

    Dorjnamjil, Amirlan (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Open Access
    A small wind farm's layout is optimized with the use of genetic algorithms. The site location of the urban wind farm was chosen as the rooftop of a warehouse situated in Barcelona. In optimizing the layout, two methods are ...
  • Decay of solutions for strain gradient mixtures 

    Magaña Centelles, Marc (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Restricted access - author's decision
    We study the three-dimensional problem for antiplane shear deformations in the case of isotropic and homogeneous mixtures in a cylinder. Our aim is to analyze the behaviour of the solutions with respect to the time variable ...
  • Quantum delegation from fully homomorphic encryption based on Ring learning with errors 

    Cano Aguilera, Abraham (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Open Access
    Quantum computers will not likely be widespread and accessible to everyone in a foreseen future. Being capable of delegating quantum computation to untrusted parties while not losing condentiality would individuals to grant ...
  • A submodular approach to the efficient placement of electric vehicle charging stations 

    Barceló Castelló, Mariola (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Restricted access - author's decision
    Our contribution is an algorithm for the cardinality constrained placement of EV charge stations that achieves a $1-\frac{1}{e}-\epsilon$ (63\%) approximation guarantee with a computational complexity of $\mathcal{O}(n ...
  • Properties for Voronoi diagrams of arbitrary order in the sphere 

    De Las Heras Parrilla, Andrea (Universitat Politècnica de Catalunya, 2021-10)
    Master thesis
    Open Access
    In this thesis we study properties for spherical Voronoi diagrams of order $k$, SV_k(U)$ using different tools: the geometry of the sphere, a labeling for the edges of $SV_k(U)$, and the inversion transformation. Among the ...
  • The equivalence of codes 

    Dixon, James Edward (Universitat Politècnica de Catalunya, 2021-07)
    Master thesis
    Open Access
    When discussing equivalent codes, the literature tends to define equivalence differently for linear or nonlinear codes. For non-linear codes, one normally defines equivalence based on a permutation of coordinates and ...
  • The geometry of quantum codes 

    Puig Pericas, Pablo (Universitat Politècnica de Catalunya, 2021-07)
    Master thesis
    Open Access
    Quantum particles are continuously interacting with the environment hence quantum information is always susceptible to errors. Consequently when encoding information into quantum bits a special treatment is required such ...
  • Mathematical analysis of desensitization of G protein-coupled receptors 

    Valdes Martin, Roger (Universitat Politècnica de Catalunya, 2021-07)
    Master thesis
    Open Access
    G protein-coupled receptors are integral membrane proteins responsible for signal transduction from outside to inside the cell, and the study of their functional conditions may determine the healthy or pathological state ...
