    In this article I show how to obtain a powerful and truthful explanation of the failure of sorites arguments combining an adaptation of the Wide Set Theory formulated by Formato and Gerla and the concept of deep ...

  • The estimation of electric power losses in electrical networks by fuzzy regression model using genetic algorithm 

    Mogilenko, A V; Pavlyuchenko, D A (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
    Article

    This paper presents the comparative study for fuzzy regression model using linear programming, fuzzy regression model using genetic algorithms and standard regression model. The fuzzy and standard models were developed for ...

  • Formalization of provenes fuzzy functional depandency in fuzzy databases 

    Dukić, Nedžad; Avdagić, Zikrija (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
    Article
    Accés obert
    In this paper we establish equivalence between a theory of fuzzy functional dependences and a fragment of fuzzy logic. We give a way to interpret fuzzy functional dependences as formulas in fuzzy logic. This goal is ...

    Atanassov, Krassimir T.; Papadopoulos, Basil K; Syropoulos, Apostolos (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
    Article
    Accés obert
    In a recent paper by one of the authors it has been shown that there is a relationship between algebraic structures and labeled transition systems. Indeed, it has been shown that an algebraic structures can be viewed as ...
