  • Results on the Spinc-genus 

    Zampa, Sarah Juliet (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Restricted access - author's decision
    In this work, we study manifolds with a Spin-c-structure, and give results on a Spin-c-genus derived from the Witten genus. We also implement codes in order to compute this genus on usual manifolds.
  • Spatial dynamics of Hepatitis B virus with its δ-satellite and defective interfering particles 

    Albó Delgado, Ariadna (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    This project provides an indepth analysis of the spatio-temporal dynamics of the system Hepatitis B Virus (HBV) - Hepatitis Delta Virus (HDV) - Defective interfering particles (DIPs). HDV is a virus satellite that co-infects ...
  • High performance computing for flexoelectric devices 

    Manyer Fuertes, Jordi (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    This exiting development requires a robust mathematical and computational framework for solving flexoelectric boundary value problems, mathematically a coupled system of 4th-order partial differential equations, in general ...
  • Mathematical and computational modeling of shape-morphing surfaces 

    Guzmán De la O, Nino (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    Euglenids are protists unicellular flagellates made of parallel proteinaceous strips and microtubules located underneath the plasma membrane, they exhibit a highly intriguing shape morphing mechanism that permits them to ...
  • Spectral analysis of Dirac operators on domains 

    Gallegos Saliner, Jose Maria (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    Relativistic models in quantum mechanics have attracted a lot of attention in recent years, for instance, because of their applications to the study of graphene. In this work, we review the main tools to formulate confining ...
  • Theoretical and computational modeling of charge transport in flexo-photovoltaics 

    De La Torre Israel, Sergi (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    In this thesis, a model to describe the flexophotovoltaic effect is formulated by coupling the flexoelectricity equations with the drift-diffusion current equations. The resulting system of non-linear PDEs is numerically ...
  • Computer-Assited Proofs in Dynamics 

    Fernández Pinto, Aaron (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Restricted access - author's decision
    Interval analysis is presented as a solution to obtain rigorous results using computers. We present a methodology of computer-assisted proofs which involves the use of interval computations. In this thesis we introduce the ...
  • Fast solution of parametric incompressible flow problems with application to microfluidics 

    Borrás Fernández, Álvaro (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    The process of design in computational fluid dynamics often involves queries to a similar set of problems, which may be viewed together as a single problem with parametrized data. These parameters can be seen as extra ...
  • Testing Precessing Bar Models in Gaia Data 

    Pardo Araujo, Celsa (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Restricted access - confidentiality agreement
    In this work we explore the origin of the Galactic warp, which is a deformation of the Galactic disc forming its typical S-shape when viewed edge-on. This novel theory is based on the idea of a small misalignment between ...
  • Additive MDS Codes 

    Gamboa Quintero, Guillermo Andres (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Restricted access - author's decision
    In this master thesis, we present examples of additive nonlinear MDS codes over nonprime fields. Moreover, we prove the MDS conjecture for additive nonlinear codes for the alphabets F9 and F16, preserving linearity over ...
  • Linkable Attribute-based Signature 

    Masip Ardévol, Héctor (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Open Access
    Attribute-based signatures, as introduced by Maji et al. [MPR11] allow to generate anonymously a signature for a message on behalf of a signing policy. To sign a message, a private attribute that satises the signing policy ...
  • The second-order problem for singular Lagrangian field theories in the k-presymplectic formulation 

    Adame Carrillo, David (Universitat Politècnica de Catalunya, 2020-10)
    Master thesis
    Restricted access - author's decision
    In general, the system of 2nd-order partial differential equations given by the Euler--Lagrange equations of classical field theories are not compatible for singular Lagrangians. This is the so-called second-order problem. ...
