  • Time decay for several porous thermoviscoelastic systems of Moore-Gibson-Thompson type 

    Bazarra, Noelia; Fernández, Jose R.; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2021-10-27)
    Article
    Open Access
    In this paper, we consider several problems arising in the theory of thermoelastic bodies with voids. Four particular cases are considered depending on the choice of the constitutive tensors, assuming different dissipation ...
  • On anonymous and weighted voting systems 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer Nature, 2021-04-27)
    Article
    Restricted access - publisher's policy
    Many bodies around the world make their decisions through voting systems in which voters have several options and the collective result also has several options. Many of these voting systems are anonymous, i.e., all voters ...
  • Weak null, necessary defender and necessary detractor players: characterizations of the Banzhaf and the Shapley bisemivalues 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (Springer, 2021-06-16)
    Article
    Open Access
    We focus on bicooperative games, a variation of the classic cooperative games and, in particular, on the Banzhaf and the Shapley bisemivalues defined on these games. We consider three special classes of players: weak null, ...
  • On the axiomatic characterization of the coalitional multinomial probabilistic values 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (Springer Nature, 2021-05-13)
    Article
    Restricted access - publisher's policy
    The coalitional multinomial probabilistic values extend the notion of multinomial probabilistic value to games with a coalition structure, in such a way that they generalize the symmetric coalitional binomial semivalues ...
  • An a priori error analysis of a porous strain gradient model 

    Baldonedo, Jacobo; Fernández, José Ramón; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (Wiley-VCH, 2021-09-04)
    Article
    Restricted access - publisher's policy
    In this work, we consider, from the numerical point of view, a boundary-initial value problem for non-simple porous elastic materials. The mechanical problem is written as a coupled hyperbolic linear system in terms of ...
  • Influence decision models: from cooperative game theory to social network analysis 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián (Elsevier, 2021-02)
    Article
    Restricted access - publisher's policy
    Cooperative game theory considers simple games and influence games as essential classes of games. A simple game can be viewed as a model of voting systems in which a single alternative, such as a bill or an amendment, is ...
  • Decay of quasi-static porous-thermo-elastic waves 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2021-06)
    Article
    Restricted access - publisher's policy
    We study the behavior in time of the solutions to several systems of equations for porous-thermo-elastic problems when one of the variables is considered to be quasi-static or, in other words, whose second time derivative ...
  • 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
    Open Access
    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 ...
