    • An extension and an alternative characterization of May’s theorem 

      Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer, 2021-03-14)
      Article
      Accés obert
      The context of this work is a voting scenario in which each voter expresses his/her level of affinity about a proposal, by choosing a value in the set J={-j,…,-1,0,1,…,j}, and these individual votes produce a collective ...

    • An appropriate way to extend the Banzhaf index for multiple levels of approval 

      Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer Nature, 2021-01-03)
      Article
      Accés obert
      The Banzhaf power index for games admits several extensions if the players have more than two ordered voting options. In this paper we prove that the most intu-itive and recognized extension ...

    • On the enumeration of Boolean functions with distinguished variables 

      Freixas Bosch, Josep (Springer Nature, 2020-11-18)
      Article
      Accés obert
      Boolean functions have a fundamental role in neural networks and machine learning. Enumerating these functions and significant subclasses is a highly complex problem. Therefore, it is of interest to study subclasses that ...

    • A characterization of weighted simple games based on pseudoweightings 

      Freixas Bosch, Josep (2020-09-14)
      Article
      Accés obert
      The paper provides a new characterization of weighted games within the class of simple games. It is based on a stronger form of the point-set-additive pseudoweighting property of simple games. The characterization obtained ...

    • Exponential decay of solutions in type II porous-thermo-elasticity with quasi-static microvoids 

      Magaña Nieto, Antonio; Miranville, Alain; Quintanilla de Latorre, Ramón (2020-12-15)
      Article
      Accés obert
      In this note we study the problem proposed by the one-dimensional thermo-porous-elasticity of type II with quasi-static microvoids or, in mathematical terms, when the second time derivative of the volume fraction is so ...

    • A poro-thermoelastic problem with dissipative heat conduction 

      Bazarra, Noelia; Fernández, Jose R.; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2020-07-18)
      Article
      Accés obert
      In this work, we study from the mathematical and numerical points of view a poro-thermoelastic problem. A long-term memory is assumed on the heat equation. Under some assumptions on the constitutive tensors, the resulting ...

    • Exponential decay in one-dimensional Type II/III thermoelasticity with two porosities 

      Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2020-07-30)
      Article
      Accés obert
      In this paper we consider the theory of thermoelasticity with a double porosity structure in the context of the Green-Naghdi types II and III heat conduction models. For the type II, the problem is given by four hyperbolic ...

    • Some properties for bisemivalues on bicooperative games 

      Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2020-02-29)
      Article
      Accés obert
      In this work, we focus on bicooperative games, a variation of the classic cooperative games, and investigate the conditions for the coefficients of the bisemivalues—a generalization of semivalues for cooperative games—necessary ...

    • The Banzhaf value for cooperative and simple multichoice games 

      Freixas Bosch, Josep (2020-02)
      Article
      Accés obert
      This article proposes a value which can be considered an extension of the Banzhaf value for cooperative games. The proposed value is defined on the class of j-cooperative games, i.e., games in which players choose among a ...

    • Numerical analysis of a dual-phase-lag model involving two temperatures 

      Bazarra, Noelia; Fernández, José Ramón; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2020-03-30)
      Article
      Accés obert
      In this paper, we numerically analyse a phase-lag model with two temperatures which arises in the heat conduction theory. The model is written as a linear partial differential equation of third order in time. The variational ...

    • A problem with viscoelastic mixtures: numerical analysis and computational experiments 

      Fernández, José Ramón; Masid, Maria; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2021)
      Article
      Accés obert
      In this paper, we study, from the numerical point of view, a dynamic problem involving a mixture of two viscoelastic solids. The mechanical problem is written as a system of two coupled partial differential equations. Its ...

    • On the linear thermoelasticity with two porosities: numerical aspects 

      Bazarra, Noelia; Fernández, José Ramón; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-10-30)
      Article
      Accés restringit per política de l'editorial
      In this work we analyze, from the numerical point of view, a dynamic problem involving a thermoelastic rod. Two porosities are considered: the first one is the macro-porosity, connected with the pores of the material, and ...
