  • On the enumeration of bipartite simple games 

    Freixas Bosch, Josep; Samaniego Vidal, Daniel (2021-07-15)
    Article
    Restricted access - publisher's policy
    This paper provides a classification of all monotonic bipartite simple games. The problem we deal with is very versatile since simple games are inequivalent monotonic Boolean functions, functions that are used in many ...
  • An extension and an alternative characterization of May’s theorem 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer, 2021-03-14)
    Article
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Open Access
    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
    Open Access
    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
    Open Access
    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
    Open Access
    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 (2019-12-06)
    Article
    Open Access
    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 ...
