    El grupo de innovación GRAPA ( GRupo de la Evaluación de la Práctica Académica ) d el proyecto RIMA de la Universitat Politècnica de Catalunya ha elaborado una serie de criterios , en forma de rúbrica, como buenas prácticas ...
  • Wind turbine fault detection through principal component analysis and statistical hypothesis testing 

    Pozo Montero, Francesc; Vidal Seguí, Yolanda (2016-10-31)
    Article
    Accés obert
    This work addresses the problem of online fault detection of an advanced wind turbine benchmark under actuators (pitch and torque) and sensors (pitch angle measurement) faults of different type. The fault detection scheme ...
  • Switching frequency regulation in sliding mode control by a hysteresis band controller 

    Repecho del Corral, Víctor; Biel Solé, Domingo; Olm Miras, Josep Maria; Fossas Colet, Enric (2016-02-01)
    Article
    Accés obert
    Fixing the switching frequency is a key issue in sliding mode control implementations. This paper presents a hysteresis band controller capable of setting a constant value for the steady-state switching frequency of a ...
  • A chaotic secure communication system design based on iterative learning control theory 

    Acho Zuppa, Leonardo (Multidisciplinary Digital Publishing Institute, 2016-10-01)
    Article
    Accés obert
    This paper presents an application of Iterative Learning Control (ILC) theory to secure communication system design by using chaotic signals, where the logistic-map is employed as a source of chaos. Meanwhile, the ILC ...
  • On fuzzy-qualitative descriptions and entropy 

    Prats Duaygues, Francesc; Roselló Saurí, Llorenç; Sánchez Soler, Monica; Agell Jané, Núria (2016-08-01)
    Article
    Accés restringit per política de l'editorial
    This paper models the assessments of a group of experts when evaluating different magnitudes, features or objects by using linguistic descriptions. A new general representation of linguistic descriptions is provided by ...
  • Abelian Cayley digraphs with asymptotically large order for any given degree 

    Aguiló Gost, Francisco de Asis L.; Fiol Mora, Miquel Àngel; Pérez Mansilla, Sonia (2016-04-29)
    Article
    Accés obert
    Abelian Cayley digraphs can be constructed by using a generalization to Z(n) of the concept of congruence in Z. Here we use this approach to present a family of such digraphs, which, for every fixed value of the degree, ...
  • Non-regularised inverse finite element analysis for 3D traction force microscopy 

    Muñoz Romero, José (2016-06-10)
    Article
    Accés obert
    The tractions that cells exert on a gel substrate from the observed displacements is an increasingly attractive and valuable information in biomedical experiments. The computation of these tractions requires in general ...
  • Non-commutative integrable systems on b-symplectic manifolds 

    Miranda Galcerán, Eva; Kiesenhoferb, Anna (Springer, 2016)
    Article
    Accés obert
    In this paper we study noncommutative integrable systems on b-Poisson manifolds. One important source of examples (and motivation) of such systems comes from considering noncommutative systems on manifolds with boundary ...
  • New offset-free method for model predictive control of open channels 

    Horváth, Klaudia; Galvis, Eduard; Gómez Valentín, Manuel; Rodellar Benedé, José (2015-08)
    Article
    Accés restringit per política de l'editorial
    Irrigation or drainage canals can be controlled by model predictive control (MPC). Applying MPC with an internal model in the presence of unknown disturbances in some cases can lead to steady state offset. Therefore an ...
  • Decisiveness indices are semiindices: addendum 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    In the paper Decisiveness indices are semiindices (Freixas and Pons, 2016) it was shown that any decisiveness index obtained from an anonymous probability distribution is a semiindex, and that the converse is not true. In ...
