  • A geometric approach to dense Cayley digraphs of finite Abelian groups 

    Aguiló Gost, Francisco de Asis L.; Fiol Mora, Miquel Àngel; Pérez Mansilla, Sonia (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We give a method for constructing infinite families of dense (or eventually likely dense) Cayley digraphs of finite Abelian groups. The diameter of the digraphs is obtained by means of the related {\em minimum distance ...
  • The Kernel Matrix Diffie-Hellman assumption 

    Morillo Bosch, M. Paz; Rafols Salvador, Carla; Villar Santos, Jorge Luis (Springer, 2016)
    Comunicació de congrés
    Accés obert
    We put forward a new family of computational assumptions, the Kernel Matrix Diffie-Hellman Assumption. Given some matrix A sampled from some distribution D, the kernel assumption says that it is hard to find “in the exponent” ...
  • Sensor fault detection in a damage detection approach based on piezodiagnostics 

    Ruiz Ordóñez, Magda; Camacho-Navarro, Jhonatan; Villamizar Mejía, Rodolfo; Mujica Delgado, Luis Eduardo (2016)
    Text en actes de congrés
    Accés obert
    Online monitoring systems demand an adequate operation of sensor system used to acquire structural state measurements. If a damaged sensor record is incorporated in the diagnosis algorithm, it could be generate uncertainties ...
  • Sensor selection based on principal component analysis for fault detection in wind turbines 

    Pozo Montero, Francesc; Vidal Seguí, Yolanda (2016)
    Text en actes de congrés
    Accés obert
    Growing interest for improving the reliability of safety-critical structures, such as wind turbines, has led to the advancement of structural health monitoring (SHM). Existing techniques for fault detection can be broadly ...
  • Fault tolerant control design of floating offshore wind turbines 

    Rodellar Benedé, José; Tutivén Gálvez, Christian; Acho Zuppa, Leonardo; Vidal Seguí, Yolanda (2016)
    Text en actes de congrés
    Accés obert
    This work is concerned with active vibration mitigation in wind turbines (WT) but not through the use of specifically tailored devices. Instead, a general control scheme is designed for torque and pitch controllers based ...
  • Multidimensional big data processing for damage detection in real pipelines using a smart pig tool 

    Ruiz Ordóñez, Magda; Mujica Delgado, Luis Eduardo; Alférez Baquero, Edwin Santiago; Quintero, Mario; Villamizar Mejía, Rodolfo (2016)
    Text en actes de congrés
    Accés obert
    The history of the hydrocarbons business in Colombia dates back to the early twentieth century where mining and energy sector has been one of the principal pillars for the its development. Thus, the pipelines currently in ...
  • Embedded piezodiagnostics for online structural damage detection based on PCA algorithm 

    Camacho-Navarro, Jhonatan; Ruiz Ordóñez, Magda; Villamizar Mejía, Rodolfo; Mujica Delgado, Luis Eduardo; Ariza, Fabian (2016)
    Text en actes de congrés
    Accés obert
    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 ...
