    • On the time decay in phase-lag thermoelasticity with two temperatures 

      Magaña Nieto, Antonio; Miranville, Alain; Quintanilla de Latorre, Ramón (AMER INST MATHEMATICAL SCIENCES-AIMS, 2019-09-12)
      Article
      Accés obert
      The aim of this paper is to study the time decay of the solutions for two models of the one-dimensional phase-lag thermoelasticity with two temperatures. The first one is obtained when the heat flux vector and the inductive ...

    • Exponential stability in three-dimensional type III thermo-porous-elasticity with microtemperatures 

      Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2020-04)
      Article
      Accés obert
      We study the time decay of the solutions for the type III thermoelastic theory with microtemperatures and voids. We prove that, under suitable conditions for the constitutive tensors, the solutions decay exponentially. ...

    • The neighborhood role in the linear threshold rank on social networks 

      Riquelme Csori, Fabián; Gonzalez Cantergiani, Pablo; Molinero Albareda, Xavier; Serna Iglesias, María José (2019-08-15)
      Article
      Accés obert
      Centrality and influence spread are two of the most studied concepts in social network analysis. Several centrality measures, most of them, based on topological criteria, have been proposed and studied. In recent years new ...

    • An axiomatization for two power indices for (3,2)-simple games 

      Bernardi, Giulia; Freixas Bosch, Josep (2019-01-01)
      Article
      Accés obert
      The aim of this work is to give a characterization of the Shapley–Shubik and the Banzhaf power indices for (3,2)-simple games. We generalize to the set of (3,2)-simple games the classical axioms for power indices on simple ...

    • Measuring satisfaction and power in influence based decision systems 

      Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2019-06-15)
      Article
      Accés obert
      We introduce collective decision-making models associated with influence spread under the linear threshold model in social networks. We define the oblivious and the non-oblivious influence models. We also introduce the ...

    • On the uniqueness and analyticity in viscoelasticity with double porosity 

      Bazarra, Noelia; Fernández, José Ramón; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-04-01)
      Article
      Accés obert
      In this paper we analyze the system of equations that models the behaviour of materials with a double porous structure. We introduce dissipation mechanisms in both structures. We show existence, uniqueness and analyticity ...

    • Bounds for the Nakamura number 

      Freixas Bosch, Josep; Kurz, Sascha (Springer, 2019-04)
      Article
      Accés obert
      The Nakamura number is an appropriate invariant of a simple game to study the existence of social equilibria and the possibility of cycles. For symmetric (quota) games its number can be obtained by an easy formula. For ...

    • Qualitative results for a mixture of Green-Lindsay thermoelastic solids 

      Magaña Nieto, Antonio; Muñoz Rivera, Jaime E.; Naso, Maria Grazia; Quintanilla de Latorre, Ramón (2018-07)
      Article
      Accés obert
      We study qualitative properties of the solutions of the system of partial differential equations modeling thermomechanical deformations for mixtures of thermoelastic solids when the theory of Green and Lindsay for the ...

    • A parameterization for a class of complete games with abstention 

      Freixas Bosch, Josep; Tchantcho, Bertrand; Tsague, Bill Procès (2019-02-28)
      Article
      Accés obert
      Voting games with abstention are voting systems in which players can cast not only yes and no vote, but are allowed to abstain. This paper centers on the structure of a class of complete games with abstention. We obtain, ...

    • Exponential stability in type III thermoelasticity with microtemperatures 

      Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2018-10)
      Article
      Accés obert
      In this paper we consider the type III thermoelastic theory with microtemperatures. We study the time decay of the solutions and we prove that under suitable conditions for the constitutive tensors, the solutions decay ...

    • Satisfaction and power in unanimous majority influence decision models 

      Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2018-07)
      Article
      Accés obert
      We consider decision models associated with cooperative influence games, the oblivious and the non-oblivious influence models. In those models the satisfaction and the power measures were introduced and studied. We analyze ...

      Bazarra, Noelia; Fernández, José Ramón; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-09-01)
      Article
      Accés obert
      In this paper we consider the one-dimensional version of thermoelasticity with two porous structures and porous dissipation on one or both of them. We first give an existence and uniqueness result by means of semigroup ...
