      Determination of the optimal insulation thickness is of great relevance in many thermal engineering applications. In this paper, a simple optimization strategy based on the Lagrange multipliers is presented. The optimal ...
    • Adapting Broyden method to handle linear constraints imposed via Lagrange multipliers 

      Rodríguez Ferran, Antonio; Huerta, Antonio (Wiley and Sons, 1999-09)
      Article

      Various non-linear equation solvers are adapted to handle linear constraints via the Lagrange-multiplier technique. This adaptation process turns out to be quite straightforward for Newton-Raphson methods and rank-two ...
    • Imposing essential boundary conditions in mesh-free methods 

      Fernández Méndez, Sonia; Huerta, Antonio (2004-03)
      Article
      Accés obert
      Imposing essential boundary conditions is a key issue in mesh-free methods. The mesh-free interpolation does not verify the Kronecker delta property and, therefore, the imposition of prescribed values is not as straightforward ...
    • Stochastic resource allocation with a backhaul constraint for the uplink 

      Rubio López, Javier; Muñoz Medina, Olga; Pascual Iserte, Antonio; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés obert
      We propose a novel stochastic radio resource alloca- tion strategy for the uplink that achieves long-term fairness in terms of similar bitrates considering backhaul and air-interface capacity limitations. We focus on a ...
