    • Uncertainty analysis in two-terminal impedance measurements with residual correction 

      Torrents Dolz, Josep M.; Pallàs-Areny, Ramon (Institute of Electrical and Electronics Engineers, 2001-05)
      Text en actes de congrés
      Accés obert
      Residual impedance correction in impedance analyzers when using an asymmetrical test fixture needs three reference measurements, usually open circuit, short circuit, and load (meaning an impedance close to the impedance ...

    • Uncertainty factors in time-interval measurements in ballistocardiography 

      Gómez Clapers, Joan; Serra Rocamora, Albert; Casanella Alonso, Ramón; Pallàs-Areny, Ramon (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      There is a growing interest on measuring time intervals between the J peak of the ballistocardiogram (BCG) and several features of other cardiovascular signals such as the ECG in order to obtain cardiovascular function ...
    • Variations in breathing patterns increase low frequency contents in HRV spectra 

      García González, Miguel Ángel; Vázquez Seisdedos, Carlos; Pallàs-Areny, Ramon (Institute of Physics Publishing, 2000)
      Article
      Accés obert
      This paper shows that variations in breathing patterns broaden heart rate variability (HRV) spectral bands and increase the power amplitude of low-frequency bands. Because of these influences, spectral markers for HRV ...
