  • On weights and quotas for weighted majority voting games 

    Molinero Albareda, Xavier; Serna Iglesias, María José; Taberner Ortiz, Marc (2021-12)
    Article
    Open Access
    In this paper, we analyze the frequency distributions of weights and quotas in weighted majority voting games (WMVG) up to eight players. We also show different procedures that allow us to obtain some minimum or minimum ...
  • Numerical analysis of a problem involving a viscoelastic body with double porosity 

    Bazarra, Noelia; Fernández, Jose R.; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2022-02)
    Article
    Restricted access - publisher's policy
    We study from a numerical point of view a multidimensional problem involving a vis- coelastic body with two porous structures. The mechanical problem leads to a linear system of three coupled hyperbolic partial differential ...
  • Extremal coalitions for influence games through swarm intelligence-based methods 

    Riquelme Csori, Fabián; Olivares Ordenes, Rodrigo; Muñoz Martínez, Francisco José; Molinero Albareda, Xavier; Serna Iglesias, María José (2022)
    Article
    Open Access
    An influence game is a simple game represented over an influence graph (i.e., a labeled, weighted graph) on which the influence spread phenomenon is exerted. Influence games allow applying different properties and parameters ...
  • A critical analysis on the notion of power 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer, 2021-08-12)
    Article
    Restricted access - publisher's policy
    In this paper we discuss on several ways to extend power indices defined on simple games to the context of (j, 2)-games, i.e., games with 2 possible outputs and j possible input levels. The purpose of this paper is more ...
  • 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
    Open Access
    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
    Open Access
    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, 2022-01)
    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
    Open Access
    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 ...
