Exponential decay in one-dimensional Type II/III thermoelasticity with two porosities
(2020-04-26)
Article
Restricted access - publisher's policyIn 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
(2020-02-29)
Article
Restricted access - publisher's policyIn 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
(2020-02)
Article
Restricted access - publisher's policyThis 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
(2019-12-27)
Article
Restricted access - publisher's policyIn 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
(2019-12-06)
Article
Restricted access - publisher's policyIn 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 ... -
On the linear thermoelasticity with two porosities: numerical aspects
(2019-10-30)
Article
Restricted access - publisher's policyIn this work we analyze, from the numerical point of view, a dynamic problem involving a thermoelastic rod. Two porosities are considered: the first one is the macro-porosity, connected with the pores of the material, and ... -
On the time decay in phase-lag thermoelasticity with two temperatures
(AMER INST MATHEMATICAL SCIENCES-AIMS, 2019-09-12)
Article
Open AccessThe 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
(2019-09-02)
Article
Restricted access - publisher's policyWe 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
(2019-08-15)
Article
Restricted access - publisher's policyCentrality 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
(2019-01-01)
Article
Open AccessThe 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
(2019-06-15)
Article
Restricted access - publisher's policyWe 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
(2019-04-01)
Article
Open AccessIn 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 ...
