  • Adjoint-based PDE-constrained optimization using HPC techniques 

    Peredo Andrade, Oscar Francisco (Universitat Politècnica de Catalunya, 2013-10-02)
    Master thesis
    Open Access
    This work focuses in the utilization of current HPC technologies to explore mathematical optimization algorithms in which a PDE acts as main constraint. A development framework is proposed, together with a novel application ...
  • Disseny de lents progressives 

    Casanellas Peñalver, Glòria (Universitat Politècnica de Catalunya, 2014-02)
    Master thesis
    Restricted access - author's decision
    Presbyopia starts to show up at the age of 40. The lens of the eye loses its flexibility to the point where we can no longer accommodate clearly in near vision. Progression-addition lenses correct the lack of accommodation ...
  • Edge-elements formulation of 3D CSEM in geophysics : a parallel approach 

    Castillo Reyes, Octavio (Universitat Politècnica de Catalunya, 2017-10-23)
    Doctoral thesis
    Open Access
    Electromagnetic methods (EM) are an invaluable research tool in geophysics whose relevance has increased rapidly in recent years due to its wide industrial adoption. In particular, the forward modelling of three-dimensional ...
  • Estrategias de descomposición en dominios para entornos Grid 

    Otero Calviño, Beatriz (Universitat Politècnica de Catalunya, 2007-04-13)
    Doctoral thesis
    Open Access
    En este trabajo estamos interesados en realizar simulaciones numéricas basadas en elementos finitos con integración explícita en el tiempo utilizando la tecnología Grid.<br/>Actualmente, las simulaciones explícitas de ...
  • Leveraging performance of 3D finite difference schemes in large scientific computing simulations 

    De la Cruz, Raúl (Universitat Politècnica de Catalunya, 2015-11-30)
    Doctoral thesis
    Open Access
    Gone are the days when engineers and scientists conducted most of their experiments empirically. During these decades, actual tests were carried out in order to assess the robustness and reliability of forthcoming product ...
  • Numerical solution of 3-D electromagnetic problems in exploration geophysics and its implementation on massively parallel computers 

    Koldan, Jelena (Universitat Politècnica de Catalunya, 2013-10-30)
    Doctoral thesis
    Open Access
    The growing significance, technical development and employment of electromagnetic (EM) methods in exploration geophysics have led to the increasing need for reliable and fast techniques of interpretation of 3-D EM data ...
  • Particle-in-cell algorithms for plasma simulations on heterogeneous architectures 

    Sáez Pous, Xavier (Universitat Politècnica de Catalunya, 2016-01-25)
    Doctoral thesis
    Open Access
    During the last two decades, High-Performance Computing (HPC) has grown rapidly in performance by improving single-core processors at the cost of a similar growth in power consumption. The single-core processor improvement ...
