  • A domain decomposition technique for pseudospectra computations 

    Astudillo, Reinaldo; Castillo, Zenaida; Otero Calviño, Beatriz (2013)
    Conference report
    Restricted access - publisher's policy
    The pseudospectra, a tool to study the behavior of systems associated with nonnormal matrices has been considered extremely useful in the last decades, for that reason there is a recent interest in its efficient computation. ...
  • Caracterització de la interacció ió-grafè en una solució aquosa mitjançant simulació de dinàmica molecular 

    Marchena Angos, Miquel (Universitat Politècnica de Catalunya, 2015-07-01)
    Bachelor thesis
    Open Access
    A proper description of ions at aqueous interfaces is a fundamental problem which has been thoroughly studied both theoretically and experimentally for a long time. The interaction of ions with interfaces plays an important ...

  • Computation of bounds for anchor problems in limit analysis and decomposition techniques 

    Muñoz Romero, José; Rabiei, Syednima; Lyamin, Andrei; Huerta, Antonio (Springer, 2013-07-15)
    Part of book or chapter of book
    Open Access
    Numerical techniques for the computation of strict bounds in limit analyses have been developed for more than thirty years. The efficiency of these techniques have been substantially improved in the last ten years, and ...
  • Dynamics of Many-Body Quantum Systems 

    Giménez Grau, Aleix (Universitat Politècnica de Catalunya, 2015-07-03)
    Bachelor thesis
    Open Access
    We study the ground state and the excitations of quantum bose systems. The hypernetted chain equations (HNC) are introduced and we show that the methods based on them produce acceptable approximations of the static structure ...
  • Flamelet mathematical models for non-premixed laminar combustion 

    Carbonell Sánchez, Daniel; Pérez Segarra, Carlos David; Coelho, P.J.; Oliva Llena, Asensio (2009-02-01)
    Restricted access - publisher's policy
    Detailed numerical calculations based on the solution of the full transport equations have been compared with flamelet calculations in order to analyse the flamelet concept for laminar diffusion flames. The goal of this ...
  • Il.luminació Global per Ciutats 

    Roure Garcia, Ferran (Universitat Politècnica de Catalunya, 2011-09)
    Master thesis
    Open Access
  • Mètodes per a la resolució d'equacions no lineals amb l'operador diferències dividides 

    Corella Pérez, Sandra (Universitat Politècnica de Catalunya, 2015-07-01)
    Bachelor thesis
    Open Access
    Construcció i estudi de mètodes iteratius d'un i dos passos per a la resolució d'equacions no lineals amb l'operador diferències dividides. Estudi d'ordres i radis de convergència, comparativa de llibreries de multiprecisió ...
  • Quantum Many-Body Systems in 1D: One Dimensional Hydrogen 

    Vidal Arias, Alfredo José (Universitat Politècnica de Catalunya, 2015-06-22)
    Bachelor thesis
    Open Access
    The ground-state properties of one-dimensional spin polarized hydrogen, deuterium and tritium at zero temperature are obtained by means of Diffusion Monte Carlo calculations (DMC). The equations of state of the three ...
  • Two-dimensional modeling of steady state heat transfer in solids with use of spreadsheet (MS EXCEL) 

    Garcia Blanch, Luis (Universitat Politècnica de Catalunya / Akademia Techniczno-Humanistyczna W. Bielsku-Bialej, 2010)
    Master thesis (pre-Bologna period)
    Open Access
    In order to resolve both temperature distribution and heat flux in bodies whose geometries are not simple the analytical solutions are limited. In unsteady conditions are needed methods that would allow to calculate ...
