    • 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 ...

      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 ...
