    Text en actes de congrés
    Accés restringit per política de l'editorial
    In previous work by the authors, an aircraft turbine blade was used to show that T and Q-statistics formulation based in Principal Components Analysis (PCA) are successful indices to detect and distinguish damages. In ...
  • Active pose SLAM 

    Valencia Carreño, Rafael; Valls Miró, Jaime; Dissanayake, Gamini; Andrade-Cetto, Juan (2012)
    Text en actes de congrés
    Accés obert
    We present an active exploration strategy that complements Pose SLAM [1] and optimal navigation in Pose SLAM [2]. The method evaluates the utility of exploratory and place revisiting sequences and chooses the one that ...
