    • Control of robotic systems using differential flatness 

      Belda Ferrín, Guillem (Universitat Politècnica de Catalunya, 2015-07)
      Master thesis
      Open Access
      In this work, a coordinate change of state variables is performed for drift-less systems of dimension m+2 with 2 inputs using Goursat Normal Form. Then, we define a feedback law that will allow us to convert the original ...
    • HDG para problemas de ondas : Análisis de la dispersión numérica y aplicaciones 

      Belda Ferrín, Guillem (Universitat Politècnica de Catalunya, 2014-07)
      Bachelor thesis
      Open Access
      En este trabajo se realiza un análisis de dispersión para los métodos Continuous Galerkin (CG) y Hybridizable Discontinuous Galerkin (HDG) al ser aplicados a la ecuación de Helmholtz en 1D. Se calcula la expresión del error ...
    • Local bisection for conformal refinement of unstructured 4D simplicial meshes 

      Belda Ferrín, Guillem; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Springer, 2018)
      Conference report
      Open Access
      We present a conformal bisection procedure for local refinement of 4D unstructured simplicial meshes with bounded minimum shape quality. Specifically, we propose a recursive refine to conformity procedure in two stages, ...
    • Visualization of pentatopic meshes 

      Belda Ferrín, Guillem; Ruiz-Gironés, Eloi; Roca, Xevi (Barcelona Supercomputing Center, 2020-05)
      Conference report
      Open Access
      We propose a simple tool to visualize 4D unstructured pentatopic meshes. The method slices unstructured 4D pentatopic meshes (fields) with an arbitrary 3D hyperplane and obtains a conformal 3D unstructured tetrahedral ...
