  • On the time decay of solutions for non-simple elasticity with voids 

    Liu, Zhuangyi; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (Wiley-VCH, 2016-07-01)
    Article

    In this work we consider the non-simple theory of elastic material with voids and we investigate how the coupling of these two aspects of the material affects the behavior of the solutions. We analyze only two kind of ...
  • Decisiveness indices are semiindices 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2016-06)
    Article
    Restricted access - publisher's policy
    In this note we prove that any decisiveness index, defined for any voter as the probability of him/her being decisive, is a semiindex when the probability distribution over coalitions is anonymous, and it is a semiindex ...
  • Some properties for probabilistic and multinomial (probabilistic) values on cooperative games 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2016-01-01)
    Article
    Restricted access - publisher's policy
    We investigate the conditions for the coefficients of probabilistic and multinomial values of cooperative games necessary and/or sufficient in order to satisfy some properties, including marginal contributions, balanced ...
  • The cost of getting local monotonicity 

    Freixas Bosch, Josep; Kurz, Sascha (Elsevier, 2016-06-01)
    Article
    Restricted access - publisher's policy
    Committees with yes-no-decisions are commonly modeled as simple games and the ability of a member to influence the group decision is measured by so-called power indices. For a weighted game we say that a power index satisfies ...
  • On the complexity of exchanging 

    Molinero Albareda, Xavier; Olsen, Martin; Serna Iglesias, María José (2016-02-04)
    Article
    Restricted access - publisher's policy
    We analyze the computational complexity of the problem of deciding whether, for a given simple game, there exists the possibility of rearranging the participants in a set of j given losing coalitions into a set of j winning ...
  • Power in voting rules with abstention: an axiomatization of a two components power index 

    Freixas Bosch, Josep; Lucchetti, Roberto (2016-02-09)
    Article
    Restricted access - publisher's policy
    In order to study voting situations when voters can also abstain and the output is binary, i.e., either approval or rejection, a new extended model of voting rule was defined. Accordingly, indices of power, in particular ...
  • Exponential decay in nonsimple thermoelasticity of type III 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2016-01-15)
    Article
    Open Access
    This paper deals with the model proposed for nonsimple materials with heat conduction of type III.We analyze rst the general system of equations, determine the behavior of its solutions with respect to the time and show ...
  • Manipulation in games with multiple levels of output 

    Freixas Bosch, Josep; Parker, Cameron (2015-12)
    Article
    Restricted access - publisher's policy
    In (j,k)-games each player chooses amongst j ordered options and there are k possible outcomes. In this paper, we consider the case where players are assumed to prefer some outcomes to others, and note that when k>2 the ...
  • A method to calculate generalized mixed modified semivalues: application to the Catalan Parliament (legislature 2012-2016) 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (Springer, 2015-10-01)
    Article
    Restricted access - publisher's policy
    We focus on generalized mixed modified semivalues, a family of coalitional values. They apply to games with a coalition structure by combining a (induced) semivalue in the quotient game, but share within each union the ...
  • Identifying optimal components in a reliability system 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2008-03)
    Article
    Open Access
    The first step in a reliability optimization process is to make a reliability assessment for each component in the system. If this assessment is made in a qualitative way, by grouping together components with the same ...
