    • A DUE based bilevel optimization approach for the estimation of time sliced OD matrices 

      Bullejos, Manuel; Barceló Bugeda, Jaime; Montero Mercadé, Lídia (2014)
      Text en actes de congrés
      Accés obert
      Traffic management applications are supported by dynamic models fed with realistic real-time demand matrices in order to find efficient solutions in the short-term horizon. OD matrices have to be estimated from historic ...

    • Design of single shaped reflector antennas for synthesis of shaped contour beams using genetic algorithms 

      Vall-Llossera Ferran, Mercedes Magdalena; Rius Casals, Juan Manuel; Duffo Ubeda, Núria; Cardama Aznar, Ángel (JOHN WILEY & SONS INC, 2000-12-31)
      Article
      Accés obert
      A genetic algorithm (GA) has been developed for designing single-shaped reflector antennas for the synthesis of shaped contour beams. The graphical processing technique is used in order to obtain the antenna radiation ...

    • DNS of turbulent natural convection flows on the MareNostrum supercomputer 

      Trias Miquel, Francesc Xavier; Gorobets, Andrei; Soria Guerrero, Manel; Oliva Llena, Asensio (2009)
      Article
      Accés restringit per política de l'editorial
      A code for the direct numerical simulation (DNS) of incompressible turbulent flows that provides a fairly good scalability for a wide range of computer architectures has been developed. The spatial discretization of the ...

    • Interior-point solver for convex separable block-angular problems 

      Castro Pérez, Jordi (2014)
      Report de recerca
      Accés obert
      Constraints matrices with block-angular structures are pervasive in Optimization. Interior-point methods have shown to be competitive for these structured problems by exploiting the linear algebra. One of these approaches ...
