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 obertResidual 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'editorialThere 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 obertThis 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 ...
