    This work discusses a methodology used to implement a data-driven strategy for Structural Health Monitoring. First, the instrumentation of the equipment is detailed by describing the main components to be installed in the ...
  • Sobre la inversa de grupo de grafos distancia regulares 

    Carmona Mejías, Ángeles (Editorial Universidad de Almería, 2015)
    Text en actes de congrés
    Accés obert
    En este trabajo estudiamos cuando la inversa de grupo del Laplacia no com- binatorio de un grafo distancia–regular es una M –matriz. Cuando esto ocurre decimos que el grafo tiene la M –propiedad. Aquí probamos que sólo ...
  • Stabbing circles for some sets of Delaunay segments 

    Claverol Aguas, Mercè; Khramtcova, Elena; Papadopoulou, Evanthia; Saumell, Maria; Seara Ojea, Carlos (2016)
    Text en actes de congrés
    Accés obert
    Let S be a set of n segments in the plane such that, for every segment, its two endpoints are adjacent in the Delaunay triangulation of the set of endpoints of all segments in S. Our goal is to compute all the combinatorially ...
  • 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 ...
  • Stabbing circles for sets of segments in the plane 

    Claverol Aguas, Mercè; Khramtcova, Elena; Papadopoulou, Evanthia; Saumell, Maria; Seara Ojea, Carlos (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Stabbing a set S of n segments in the plane by a line is a well-known problem. In this paper we consider the variation where the stabbing object is a circle instead of a line. We show that the problem is tightly connected ...
  • Solar radiation pressure assisted transfers between Lissajous orbits of the Sun-Earth system 

    Stefania, Soldini; Gomez Muntané, Gerard; Masdemont Soler, Josep; Camilla, Colombo; Walker, Scott (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This article investigates a propellant-free transfer between Lissa jous orbits in the Sun-Earth system modelled as a photo-gravitational circular restricted three body p roblem. The geometry of the phase space around the ...
  • Ordered durability functions estimation for inspection-based data: a computational issue 

    Serrat Piè, Carles; Moreno Basquens, Laura (Brno Univeristy of Technology, 2014)
    Comunicació de congrés
    Accés obert
    This contribution is framed in, and is part of, the Durabiltiy of Building Facades studies carried out in the last decade in the Institut d’Estadística i Matemàtica Aplicada a l’Edificació and the Laboratori d’Edificació ...
  • 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 ...
  • Técnicas estadísticas aplicadas a la selección de valores para parámetros de metaheurísticas 

    Calvet Liñán, Laura; Juan Pérez, Ángel Alejandro; Serrat Piè, Carles (2015)
    Comunicació de congrés
    Accés obert
    La mayoría de metaheurísticas incluyen diversos parámetros que influyen en la calidad de su solución. A pesar de esto, el Problema de Selección de Valores para Parámetros no fue formalmente estudiado hasta finales del ...
