  • Pumps condition assessment in water distribution networks 

    Soldevila, Adrià; Blesa Izquierdo, Joaquim; Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Meseguer Amela, Jordi; Puig Cayuela, Vicenç (2018-01-01)
    Article
    Accés obert
    This paper presents a method for the detection of faults in electrical pumps. The method relies on the computation of two features, the pump efficiency and the hydraulic balance, that present reference values during healthy ...

    Article
    Accés obert
    An improved approach is presented to model the product particle size distribution resulting from grinding in high-pressure roll crusher with the aim to be used in standard high-pressure grinding rolls (HPGR). This approach ...
  • Ferrohydrodynamic capillary convection 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2018-09-30)
    Article
    Accés restringit per política de l'editorial
    In this work consideration is given to capillary convection on ferrofluids owing to the concentration gradient generated when a non-homogeneous magnetic field is applied. It is known that mass transfer along an interface ...
  • Autonomous vehicle control using a kinematic Lyapunov-based technique with LQR-LMI tuning

  • Fault estimation in wind turbines using a joint fault and state estimation scheme 

    Witczak, Marcin; Rotondo, Damiano; Puig Cayuela, Vicenç; Nejjari Akhi-Elarab, Fatiha; Pazera, Marcin (2017)
    Article
    Accés restringit per política de l'editorial
    This paper addresses the problem of fault estimation in wind turbines using a joint fault and state estimation scheme. The scheme assumes a set of possible faults affecting the dynamics of the wind turbine. Then, a combined ...
