    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 (2009-02-18T16:48:08Z)
    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 ...
