      Elorza, Jorge; Ferragut, Luís; Winter, Gabriel (Centro Internacional de Métodos Numéricos en Ingeniería, 1987)
      Article
      Open Access
      Al abordar la resolución de problemas no lineales mediante tecnicas de Lagrangiano aumentado es usual utilizar algoritmos del tipo
    • On the Induction of New Fuzzy Relations, New Fuzzy Operators and Their Aggregation 

      Carmona Cervelló, Neus; Elorza, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (Springer, 2013)
      Article
      Open Access
      In this paper we generate fuzzy relations and fuzzy operators using different kind of generators and we study the relationship between them. Firstly, we introduce a new fuzzy preorder induced by a fuzzy operator. We ...
    • Parametric families of fuzzy consequence operators 

      Elorza, Jorge; Burillo López, Pedro (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
      Article
      Open Access
      In a previous paper ([6]) we explored the notion of coherent fuzzy consequence operator. Since we did not know of any example in the literature of non-coherent fuzzy consequence operator, we also showed several families ...
    • Permutability of fuzzy consequence operators and fuzzy interior operators 

      Carmona, Neus; Elorza, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (2013)
      Article
      Restricted access - publisher's policy
      In this paper we study the permutability of the composition of fuzzy consequence operators (fuzzy closings) and fuzzy interior operators (fuzzy openings). We establish several characterizations and we show the relation of ...
    • Some illustrative examples of permutability of fuzzy operators and fuzzy relations 

      Carmona, Neus; Elorza, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (2014)
      Conference report
      Open Access
      Composition of fuzzy operators often appears and it is natural to ask when the order of composition does not change the result. In previous papers, we characterized permutability in the case of fuzzy consequence operators ...
    • Un método de lagrangiano aumentado para la resolución de problemas de flujo no lineal en medio no poroso 

      Ferragut, Luís; Elorza, Jorge (1985)
      Article
      Open Access
      Al estudiar el comportamiento del flujo de un fluido a través de un medio poroso se observa que para velocidades altas la ley de Darcy no es válida y requiere su sustitución por expresiones más generales. En este trabajo ...
