      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 ...

    • Numbering along advection for Gauss-Seidel and bidiagonal preconditioners 

      Córdoba, Paula; Houzeaux, Guillaume (Barcelona Supercomputing Center, 2015-05-05)
      Text en actes de congrés
      Accés obert
      Domain decomposition methods (DDM) are often chosen to precondition sparse linear systems of equations, as they are famous to well-improve the convergence of iterative solvers. But at the same time, they are difficult to ...

    • Piezoelectric elements subjected to low frequency excitation. Empirical determination of stress and frequency influence on piezoelectric parameters 

      Bernat Masó, Ernest; Mercedes Cedeño, Luis Enrique (Springer Nature, 2022-08)
      Article
      Accés obert
      Designing optimum energy harvesting devices is the aim of several developments based on numerical or analytical studies of different piezoelectric configurations that usually consider constant piezoelectric properties. ...

    • Quantum Many-Body Systems in 1D: One Dimensional Hydrogen 

      Vidal Arias, Alfredo José (Universitat Politècnica de Catalunya, 2015-06-22)
      Treball Final de Grau
      Accés obert
      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 ...

    • Stress relaxation in epithelial monolayers is controlled by the actomyosin cortex 

      Khalilgharibi, Nargess; Fouchard, Jonathan; Asadipour, Nina; Barrientos, Ricardo; Duda, Maria; Bonfanti, Alessandra; Yonis, Amina; Harris, Andrew; Mosaffa, Payman; Fujita, Yasuyuki; Kabla, Alexandre; Mao, Yanlan; Baum, Buzz; Muñoz Romero, José; Miodownik, Mark; Charras, Guillaume (2019-01-01)
      Article
      Accés obert
      Epithelial monolayers are one-cell thick tissue sheets that separate internal and external environments. As part of their function, they have to withstand extrinsic mechanical stresses applied at high strain rates. However, ...

    • Study of the effect of viscosity in drop breakup in turbulent flow 

      Fernández Stolpa, Lucas (Universitat Politècnica de Catalunya, 2021-07-12)
      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   Universität Bremen
      The systems formed by two immiscible liquids such as emulsions are of great interest in industrial processes, the emulsion formation process occurs depending on the phenomenon of the breakup of the drops of one of the ...

    • 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)
      Projecte/Treball Final de Carrera
      Accés obert
      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 ...
