  • Beam-ACO for the repetition-free longest common subsequence problem 

    Blum, Christian; Blesa Aguilera, Maria Josep; Calvo, Borja (2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this paper we propose a Beam-ACO approach for a combinatorial optimization problem known as the repetition-free longest common subsequence problem. Given two input sequences x and y over a finite alphabet S, this problem ...

    Article
    Accés restringit per política de l'editorial
    Bearing degradation is the most common source of faults in electrical machines. In this context, this work presents a novel monitoring scheme applied to diagnose bearing faults. Apart from detecting local defects, i.e., ...
  • Bearing fault diagnosis by EXIN CCA 

    Cirrincione,, Giansalvo; Henao, Humberto; Delgado Prieto, Miquel; Ortega Redondo, Juan Antonio (IEEE Computer Society Publications, 2012)
    Text en actes de congrés
    Accés obert
    EXIN CCA is an extension of the Curvilinear Component Analysis (CCA), which solves for the noninvariant CCA projection and allows representing data drawn under different operating conditions. It can be applied to data ...
