  • Polar germs and singularity invariants 

    González Alonso, Víctor (Universitat Politècnica de Catalunya, 2009-07)
    Master thesis
    Open Access
    In this work we obtain an algorithm which explicitly recovers the cluster of singular points a germ of curve from the cluster of base points of the polar germs of the curve. To achieve this, we reinterpret the problem in ...
  • The isoperimetric problem in Johnson graphs 

    Gutiérrez, Víctor Diego (Universitat Politècnica de Catalunya, 2013-11)
    Master thesis
    Open Access
    It has been recently proved that the connectivity of distance regular graphs is the degree of the graph. We study the Johnson graphs $J(n,m)$, which are not only distance regular but distance transitive, with the aim ...
  • Minimizers to reaction-diffusion PDEs, Sobolev inequalities, and monomial weights 

    Ros Oton, Xavier (Universitat Politècnica de Catalunya, 2011-07)
    Master thesis
    Restricted access - author's decision
    Reaction-diffusion equations play a central role in PDE theory and its applications to other sciences. They also play an important role in geometric problems: the problem of prescribing a curvature on a manifold and parabolic ...
  • Exploring network coding capabilities 

    Ríos Robles, André (Universitat Politècnica de Catalunya, 2012-07)
    Master thesis
    Restricted access - author's decision
    In this MSc Thesis, the principles of Network Coding will be reviewed, ranging from the description of the model to the typical applications. Also, two solutions related to privacy and security issues will be analyzed by ...
  • Linealización por realimentación de una clase de manipulador con un número arbitrario de actuadores 

    Reyes Jiménez, Àlex (Universitat Politècnica de Catalunya, 2012-10)
    Master thesis
    Open Access
    Este trabajo final de máster titulado "Linealización por reglamentación de una clase de manipulador con un número arbitrario de actuadores" estudia las salidas planas para un tipo particular de brazo robótico. El TFM que ...
  • Past, present and challenges in Yang-Mills theory 

    Tejedor Sánchez, Jose Luís (Universitat Politècnica de Catalunya, 2012-07)
    Master thesis
    Open Access
    Aquest treball tracta sobre les teories gauge de la física teòrica, la seva evolució des de el primer treball de Weyl (1918) fins als nostres dies tenint en compte el treball fonamental elaborat el 1954 per Yang i Mills que ...
  • Methods for solving 1D Stefan problems with application to contact melting 

    De Decker, Michelle (Universitat Politècnica de Catalunya, 2011-05)
    Master thesis
    Open Access
    Contact melting is the process during which a phase change material is placed in contact with a substrate that is at a temperature above the phase change temperature. This leads to melting of the phase change material and ...
  • Smoothing and untangling of meshes on parameterized surfaces 

    Gargallo Peiró, Abel (Universitat Politècnica de Catalunya, 2011-01)
    Master thesis
    Open Access
    The aim of this work is to develop a simultaneous smoothing-untangling procedure for parametrized surfaces. To this end we will extend the definition of the quality metrics for planar meshes to parametrized surface meshes. ...
  • Mathematical methods of signal processing 

    Sayols Baixeras, Narcís (Universitat Politècnica de Catalunya, 2011-11)
    Master thesis
    Open Access
    The aim of this project is to present in a systematic way the more relevant mathematical methods of signal processing, and to explore how they are applied to speech and image precessing. After explaining the more common ...
  • Transfer of energy in the nonlinear Schrödinger equationon 

    Simon López, Adrià (Universitat Politècnica de Catalunya, 2011-06)
    Master thesis
    Open Access
    This work aims to use tools of Dynamical Systems to prove that the nonlinear Schr odinger equation presents a global instability. To do that, we rst reduce this PDE to a system of ODE's of dimension N which we call the ...
