  • Aggregating fuzzy subgroups and T-vague groups 

    Boixader Ibáñez, Dionís; Mayor, Gaspar; Recasens Ferrés, Jorge (Springer, 2018-01-01)
    Article
    Accés obert
    Fuzzy subgroups and T-vague groups are interesting fuzzy algebraic structures that have been widely studied. While fuzzy subgroups fuzzify the concept of crisp subgroup, T-vague groups can be identified with quotient groups ...
  • Aggregating T-equivalence relations 

    Mayor, Gaspar; Recasens Ferrés, Jorge (2016)
    Text en actes de congrés
    Accés obert
    This contribution deals with the problem of aggregating Tequivalence relations, in the sense that we are looking for functions that preserve reflexivity, symmetry, and transitivity with respect to a given t-norm T. We ...
  • Aggregation of T-transitive Relations 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (Wiley InterScience, 2003-12)
    Article
    Accés restringit per política de l'editorial
    This article studies the aggregation of transitive fuzzy relations. We first find operators that preserve transitivity and then extend the results to aggregating operators. As special cases, means and some kind of suitable ...

    Article
    Accés obert
    Lipschitzian aggregation operators with respect to the natural T - indistin- guishability operator Et and their powers, and with respect to the residuation ! T with respect to a t-norm T and its powers are studied. A ...
  • Aggregation operators and quadric hypersurfaces 

    Recasens Ferrés, Jorge (Springer, 2013)
    Article
    Accés obert
    Aggregation operators that are quadric hypersurfaces are studied. The interest lays in the fact that the most popular aggregation operators are indeed quadric hypersurfaces.

  • Aggregation operators and the Lipschitzian condition 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (IEEE Comp. Int. Soc., 2007)
    Text en actes de congrés
    Accés obert
    Lipschitzian and kernel aggregation operators with respect to the natural T-indistinguishability operator ET and their powers are studied. A t-norm T is proved to be ETLipschitzian, and is interpreted as a fuzzy point and ...
  • Aggregation Operators Based on Indistinguishability Operators 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (Wiley InterScience, 2006-08)
    Article
    Accés restringit per política de l'editorial
    This article gives a new approach to aggregating assuming that there is an indistinguishability operator or similarity defined on the universe of discourse. The very simple idea is that when we want to aggregate two values ...
  • Aggregation, non-contradiction ans excluded-middle 

    Pradera Gómez, Ana; Trillas i Gay, Enric (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2006)
    Article
    Accés obert
    This paper investigates the satisfaction of the Non-Contradiction (NC) and Excluded-Middle (EM) laws within the domain of aggregation operators. It provides characterizations both for those aggregation operators that satisfy ...
  • Agile accelerated aging and degradation characterization of a V/F controlled induction motor in a conveyor belt process 

    García España, Claudia M.; Quevedo Casín, Joseba Jokin (2011)
    Text en actes de congrés
    Accés restringit per decisió de l'autor
    Although induction machines are reliable, they are subjected to some failures; the understanding degradation behaviour of Induction Motors (IM) is crucial for the adoption and application of health Management methodologies ...
  • Agile approach to business intelligence as a way to success
