    This study compares flat lattice girders mounted on two supports, based on various design parameters, to determine which have better structural performance and what geometries are more efficient. The fundamental goal is ...
  • One-dimensional T-preorders 

    Boixader Ibáñez, Dionís; Recasens Ferrés, Jorge (IOS Press, 2014)
    Texto en actas de congreso

    This paper studies T-preorders by using their Representation Theorem that states that every T-preorder on a set X can be generated in a natural way by a family of fuzzy subsets of X. Especial emphasis is made on the study ...
  • Energy-based design of a seismic protection system of timber platform frame buildings using energy dissipators 

    López Almansa, Francisco; Segués Aguasca, Edgar; Rodríguez Cantalapiedra, Inma (2014)
    Comunicación de congreso
    Acceso restringido por política de la editorial
    This paper deals with a new seismic protection system for timber platform frame buildings, either for retrofit or for new construction. The system consists in connecting the timber frame to a steel framed structure that ...

    El creciente interés en el uso de las mallas espaciales de acero como elementos estructurales envolventes de edificios en altura conlleva a que actualmente el concepto estructural adquiera un papel de mayor relevancia en ...
  • Indistinguishability operators generated by fuzzy numbers 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2004)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    A new way to generate indistinguishability operators coherent with the underlying ordering structure of the real Dine is given in the sense that this structure should be compatible with the betweenness relation generated ...
  • Eigenvectors and generators of fuzzy relations 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (-, 1992)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    A new geometric approach to the study of the eigenvectors is provided. The T-eigenvectors of a T-indistinguishability operator are characterized as its generators in the sense of the representation theorem of L. Valverde ...
  • Fuzzy numbers and equality relations 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (IEEE pub., 1993)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    A general approach to the concept of fuzzy number associated to a generalized equality on the real line is given. As a result, the use of triangular and trapezoidal fuzzy numbers, among other types, is justified and a ...
  • ET-Lipschitzian aggregation operators 

    Jacas Moral, Juan; Recasens Ferrés, Jorge (-, 2007)
    Texto en actas de congreso
    Acceso abierto
    Lipschitzian and kernel aggregation operators with respect to the natural Tindistinguishability operator ET and their powers are studied. A t-norm T is proved to be ET -lipschitzian, and is interpreted as a fuzzy point and ...
  • Finding close T-indistinguishability operators to a given proximity 

    Garmendia Salvador, Luis; Recasens Ferrés, Jorge (-, 2007)
    Texto en actas de congreso
    Acceso abierto
    Two ways to approximate a proximity relation R (i.e. a reflexive and symmetric fuzzy relation) by a T-transitive one where T is a continuous archimedean t-norm are given. The first one aggregates the transitive closure R ...
