    • Comparative study of trusses to determine the influence of the geometry in the structural efficiency, according to the directions of the principal stresses 

      Señís López, Roger; Brufau Niubó, Roberto; Sastre Sastre, Ramon; Carbajal Navarro, Eusebio Carlos (2015)
      Conference lecture
      Restricted access - author's decision
      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)
      Conference report
      Open Access
      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)
      Conference lecture
      Restricted access - publisher's policy
      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 ...

    • Higher education academic staff: professional identity and sense of community as the key to enhancing teaching quality 

      Sancho Vinuesa, María Teresa; Estela Carbonell, M. Rosa; Sánchez Bonvehí, Clàudia; Villalonga Pons, Joana (2014)
      Conference report
      Restricted access - publisher's policy
      This study presents an analysis of the main features of teaching community of the Catalan university system, from both the individual activity of professors and the sense of belonging to a community. The basis of the ...
    • Ensayos con túnel de viento de edificios "romo" de base circular para optimizar mallas espaciales envolventes de edificios en altura 

      Señís López, Roger; Sastre Sastre, Ramon; Brufau Niubó, Roberto; Carbajal Navarro, Eusebio Carlos (2014)
      Conference report
      Restricted access - author's decision
      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)
      Conference report
      Restricted access - publisher's policy
      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)
      Conference report
      Restricted access - publisher's policy
      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)
      Conference report
      Restricted access - publisher's policy
      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)
      Conference report
      Open Access
      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)
      Conference report
      Open Access
      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 ...
    • Aggregation operators and the Lipschitzian condition 

      Jacas Moral, Juan; Recasens Ferrés, Jorge (IEEE Comp. Int. Soc., 2007)
      Conference report
      Open Access
      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 ...
