  • On bipartite-mixed graphs 

    Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel; López Lorenzo, Nacho (Wiley, 2018-04-24)
    Article
    Accés obert
    Mixed graphs can be seen as digraphs that have both arcs and edges (or digons, that is, two opposite arcs). In this paper, we consider the case where such graphs are bipartite. As main results, we show that in this context ...
  • Planelike minimizers of nonlocal Ginzburg-Landau energies and fractional perimeters in periodic media 

    Cozzi, Matteo; Valdinoci, Enrico (2018-07-01)
    Article
    Accés obert
    We consider here a nonlocal phase transition energy in a periodic medium and we construct solutions whose interfaces lie at a bounded distance from any given hyperplane. These solutions are either periodic or quasiperiodic, ...
  • Computational of numerical semigroups by means of seeds 

    Bras Amorós, Maria; Fernández González, Julio (2018-09-01)
    Article
    Accés obert
    For the elements of a numerical semigroup which are larger than the Frobenius number, we introduce the definition of seed by broadening the notion of generator. This new concept allows us to explore the semigroup tree in ...
  • A four-body convex central configuration with perpendicular diagonals is necessarily a kite 

    Corbera, Montserrat; Cors Iglesias, Josep Maria; Roberts, Gareth E. (2018-07-01)
    Article
    Accés restringit per política de l'editorial
    We prove that any four-body convex central configuration with perpendicular diagonals must be a kite configuration. The result extends to general power-law potential functions, including the planar four-vortex problem.
  • Support stiffness monitoring of cylindrical structures using magnetostrictive transducers and the torsional mode T(0,1) 

    Quiroga Méndez, Jabid; Mujica Delgado, Luis Eduardo; Villamizar Mejía, Rodolfo; Ruiz Ordóñez, Magda (Multidisciplinary Digital Publishing Institute (MDPI), 2018-04)
    Article
    Accés obert
    In this paper, a support stiffness monitoring scheme based on torsional guided waves for detecting loss of rigidity in a support of cylindrical structures is presented. Poor support performance in cylindrical specimens ...
  • Coalition formation and stability 

    Magaña Nieto, Antonio; Carreras Escobar, Francisco (2018-06)
    Article
    Accés restringit per política de l'editorial
    This paper aims to develop, for any cooperative game, a solution notion that enjoys stability and consists of a coalition structure and an associated payoff vector derived from the Shapley value. To this end, two concepts ...
  • Features of cross-correlation analysis in a data-driven approach for structural damage assessment 

    Camacho Navarro, Jhonatan; Ruiz Ordóñez, Magda; Villamizar Mejía, Rodolfo; Mujica Delgado, Luis Eduardo; Quiroga, Jabid (Multidisciplinary Digital Publishing Institute (MDPI), 2018-05-15)
    Article
    Accés obert
    This work discusses the advantage of using cross-correlation analysis in a data-driven approach based on principal component analysis (PCA) and piezodiagnostics to obtain successful diagnosis of events in structural ...
  • The Shapley value analyzed under the Felsenthal and Machover bargaining model 

    Bernardi, Giulia; Freixas Bosch, Josep (2018-05-23)
    Article
    Accés restringit per política de l'editorial
    In 1996, Felsenthal and Machover proposed a bargaining procedure for a valuable payoff in cooperative and simple games. They proved that the value underlying their bargaining scheme was the Shapley value by showing that ...
  • An effective computational design strategy for H-infinity vibration control of large structures with information constraints 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Reza Karimi, Hamid (2018-09-15)
    Article
    Accés obert
    In this paper, we present an effective computational strategy to design high-performance decentralized controllers with partial local-state information for vibration control of large building structures. Specifically, the ...
  • Optimizing morphology through blood cell image analysis 

    Merino, Anna; Puigví, Laura; Boldú, L.; Alférez Baquero, Edwin Santiago; Rodellar Benedé, José (Wiley, 2018-05-09)
    Article
    Accés obert
    Introduction Morphological review of the peripheral blood smear is still a crucial diagnostic aid as it provides relevant information related to the diagnosis and is important for selection of additional techniques. ...
  • Image processing and machine learning in the morphological analysis of blood cells 

    Rodellar Benedé, José; Alférez Baquero, Edwin Santiago; Acevedo, Andrea; Molina Borrás, Ángel; Merino, Anna (Wiley, 2018-05-01)
    Article
    Accés obert
    Introduction: This review focuses on how image processing and machine learning can be useful for the morphological characterization and automatic recognition of cell images captured from peripheral blood smears. Methods: ...
