  • Legibilidad y letras 

    Molinero Albareda, Xavier; Laamiri, Arm (2022)
    Text en actes de congrés
    Accés obert
    In the present, there are different indices that measure the difficulty level of reading a text, i.e. the readability of a text. Different studies have been made on the frequency of occurrence of letters in several languages, ...
  • Systematic analysis of dropout causes 

    Alsina Aubach, Montserrat; Domènech Blázquez, Margarita; Freixanet de la Iglesia, Maria Josep (International Association of Technology, Education and Development (IATED), 2021)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Dropping out of first-year college students is a very common problem in universities in general, but especially in engineering and degrees in the STEM field. As a public university, we are committed to use resources as ...
  • A mathematical perspective on how test-type exams are evaluated 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2020)
    Text en actes de congrés
    Accés restringit per acord de confidencialitat
    Typically, the test type exams with binary answers (true / false) are corrected by adding a +1 to the correct answers, a -1 to the incorrect ones and 0 to non-answered questions. This mainly obeys to a purely statistic ...
  • Coalitional power indices applied to voting systems 

    Molinero Albareda, Xavier; Blasco Ruiz, Joan (2020)
    Comunicació de congrés
    Accés obert
    We describe voting mechanisms to study voting systems. The classical power indices applied to simple games just consider parties, players or voters. Here, we also consider games with a priori unions, i.e., coalitions among ...
  • The Owen and the Owen-Banzhaf values applied to the study of the Madrid Assembly and the Andalusian Parliament in legislature 2015-2019 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (Scitepress, 2019)
    Comunicació de congrés
    Accés obert
    This work focuses on the Owen value and the Owen-Banzhaf value, two classical concepts of solution defined on games with structure of coalition blocks. We provide a computation procedure for these solutions based on a ...
  • Combinatorial structures to modeling simple games and applications 

    Molinero Albareda, Xavier (American Institute of Physics (AIP), 2017)
    Text en actes de congrés
    Accés obert
    We connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined from atoms, ...
  • Ability to separate situations with a priori coalition structures by means of symmetric solutions 

    Giménez Pradales, José Miguel (2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We say that two situations described by cooperative games are inseparable by a family of solutions, when they obtain the same allocation by all solution concept of this family. The situation of separability by a family of ...
  • A new procedure to calculate the Owen value 

    Puente del Campo, María Albina; Giménez Pradales, José Miguel (2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    In this paper we focus on games with a coalition structure. Particularly, we deal with the Owen value, the coalitional value of the Shapley value, and we provide a computational procedure to calculate this coalitional value ...
  • On the construction of high dimensional simple games 

    Olsen, Martin; Kurz, Sascha; Molinero Albareda, Xavier (IOS Press, 2016)
    Text en actes de congrés
    Accés obert
    Voting is a commonly applied method for the aggregation of the preferences of multiple agents into a joint decision. If preferences are binary, i.e., “yes” and “no”, every voting system can be described by a (monotone) ...
  • Components with higher and lower risk in a reliability system 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Fundación Mapfre, 2015)
    Text en actes de congrés
    Accés obert
    A new reliability importance measure for components in a system, that we call Representativeness measure, is introduced. It evaluates to which extent the performance of a component is representative of the erformance of ...
  • Computational procedure for a wide family of mixed coalitional values 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We consider a family of mixed 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 payoff so obtained by applying ...
  • Similarities and differences between success and decisiveness 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (AA Publications, 2014)
    Text en actes de congrés
    Accés obert
    We consider binary voting systems in which a probability distribution over coalitions is known. In this broader context decisiveness is an extension of the Penrose-Banzhaf index and success an extension of the Rae index ...
