      Article
      Open Access
      The introduction of a {0,1}-valued game associated to a connected graph allows us to assign to each node a value of weighted connectivity to the different solutions that for the cooperative games are obtained by means of ...

      Conference report
      Open Access
      In decentralized systems, nodes often need to coordinate to access shared resources in a fair manner. One approach to perform such arbitration is to rely on auction mechanisms. Although there is an extensive literature ...

      Article
      Restricted access - publisher's policy
      Cooperation among nodes is fundamental for the operation of mobile ad hoc networks(MANETs). In such networks, there could be selfish nodes that use resources from other nodes to send their packets but that do not offer ...

      The number of portable devices capable of maintaining wireless communications has increased considerably in the last decade. Such mobile nodes may form a spontaneous self-configured network connected by wireless links to ...
    • A logistic approximation to the cumulative normal distribution 

      Bowling, Shannon R.; Khasawneh, Mohammad T.; Kaewkuekool, Sittichai; Cho, Byung Rae (School of Industrial and Aeronautic Engineering of Terrassa (ETSEIAT). Universitat Politècnica de Catalunya (UPC), 2009-06)
      Article
      Open Access
      This paper develops a logistic approximation to the cumulative normal distribution. Although the literature contains a vast collection of approximate functions for the normal distribution, they are very complicated, not ...
    • 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
      Open Access
      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 ...
    • A new coalitional value 

      Carreras Escobar, Francisco; Alonso Meijide, José María (2009-10-17)
      External research report
      Restricted access - author's decision
      We propose a modification of the Shapley value for monotonic games with a coalition structure. The resulting coalitional value is a twofold extension of the Shapley value in the following sense: (1) the amount obtained by ...

      Article
      Restricted access - author's decision
      In this paper we propose a new power index useful for the evaluation of each member in a committee, or democratic institution, and the degree of influence over the voting decision making system. The proposed solution is ...

      Article
      Restricted access - publisher's policy
      Binary voting systems, usually represented by simple games, constitute a main DSS topic. A crucial feature of such a system is the easiness with which a proposal can be collectively accepted, which is measured by ...
