    Article
    Accés restringit per política de l'editorial
    Based upon the standard IEEE 1309, a new calibration method for electromagnetic (EM) probes is proposed. The aforementioned method compares the electric field strength measured with the EM probe subject to calibration with ...
  • An interurban road pricing model for the Spanish network 

    Saurí Marchán, Sergi; Robusté Antón, Francesc; Salas R., M.; Argote Cabañero, Juan; Martín Alcalde, Enrique (2010)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Currently, there is not a homogeneous Road Pricing policy in Spain. Rather, various roads are tolled, though not in a uniform way and only taking into account financial considerations. For this reason, in this article we ...
  • An interval NLPV parity equations approach for fault detection and isolation of a wind farm 

    Blesa Izquierdo, Joaquim; Jiménez, Pedro; Rotondo, Damiano; Nejjari Akhi-Elarab, Fatiha; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2014-12-25)
    Article
    Accés obert
    In this paper, the problem of fault diagnosis of a wind farm is addressed using interval nonlinear parameter varying (NLPV) parity equations. Fault detection is based on the use of parity equations assuming unknown but ...
  • An interval technical indicator for financial time series forecasting 

    Ruiz Vegas, Francisco Javier; Samà Monsonís, Albert; Sanchez, German; Sanabria, José A.; Agell Jané, Núria (2011)
    Text en actes de congrés
    Accés obert
    In this work we compare the performance of some standard technical indicators with an interval technical indicator, the moving interval (MI), for time series forecasting. MI has the advantage of taking into account the ...
