    • Temporal evolution of the global trade-investment network 

      Pedraza Berengueres, Albert (Universitat Politècnica de Catalunya, 2023-06-27)
      Treball Final de Grau
      Accés obert
      En una societat cosmopolita i capitalista, l'economia global hi juga un rol molt important. Potser no ens n'adonem, però afecta la nostra manera de viure; no ho notem com a mers ciutadans, nomes els seus efectes com la ...
    • The material point method for unsaturated soils 

      Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (Thomas Telford, 2015-03)
      Article
      Accés obert
      The paper describes a three-phase single-point material point method formulation of coupled flow (water and air) for hydro-mechanical analysis of geotechnical problems involving unsaturated soils. The governing balance and ...
    • The Material Point Method: a promising computational tool in Geotechnics 

      Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2013)
      Text en actes de congrés
      Accés obert
      In recent years, the Material Point Method (MPM) has been applied to a number of geotechnical problems and has been extended to solve coupled flow-deformation problems. The dynamic formulation and the dual description of ...
    • Zero drift regions and control strategies to keep satellite in formation around triangular libration point in the restricted Sun-Earth-Moon scenario 

      Salazar, F.J.T; Winter, O. C.; Macau, E.E.N.; Masdemont Soler, Josep; Gómez Muntané, Gerard (2015-10-01)
      Article
      Accés obert
      In this work, we are interested in avoiding large variations in the mutual distances among multiple satellites and also in controlling their geometric configuration around an Earth Moon triangular point. Previous studies ...
