On the use of fractional calculus to improve the pulse arrival time (PAT) detection when using photoplethysmography (PPG) and electrocardiography (ECG) signals
(Public Library of Science (PLOS), 2024-02-16)
Article
Accés obertThe pulse arrival time (PAT) has been considered a surrogate measure for pulse wave velocity (PWV), although some studies have noted that this parameter is not accurate enough. Moreover, the inter-beat interval (IBI) time ... -
Electrical impedance tomography to measure spirometry parameters in chronic obstructive pulmonary disease patients
(Sociedad Mexicana de Ingeniería Biomedíca, 2022-12-01)
Article
Accés obertSpirometry is a test for the diagnosis of chronic obstructive pulmonary disease. It is a technique that can be intolerant due to the essential use of a mouthpiece and a clamp. This study proposes the use of electrical ... -

Tilt-to-length coupling in LISA Pathfinder: a data analysis
(American Physical Society, 2023-11-15)
Article
Accés obertWe present a study of the tilt-to-length coupling noise during the LISA Pathfinder mission and how it depended on the system’s alignment. Tilt-to-length coupling noise is the unwanted coupling of angular and lateral ... -
Rapid emission check of photovoltaic installations using time domain measurements
(2023-12-18)
Article
Accés restringit per política de l'editorialThis article represents a contribution to the Rapid Emission Check of installations project in IEC CISPR Sub Committee A (SC A) Joint Working Group 9 (JWG9). Time domain measurements are used to identify sources and critical ... -
Arousal detection by using ultra-short-term heart rate variability (HRV) analysis
(Frontiers Media SA, 2023-08-16)
Article
Accés obertIntroduction: The study of arousal is crucial as it helps to understand the role of increased physiological and psychological activation in emotions, motivation, cognitive performance, stress responses, sleep-wake cycles, ... -
Fluid-dependent single-frequency bioelectrical impedance fat mass estimates compared to digital imaging and dual X-ray absorptiometry
(2023-11-01)
Article
Accés obertThe need for a practical method for routine determination of body fat has progressed from body mass index (BMI) to bioelectrical impedance analysis (BIA) and smartphone two-dimensional imaging. We determined agreement in ... -
Strategies using time-domain measurements for radiated emissions testing in harsh environments
(2023-08-10)
Article
Accés obertPerforming in-situ radiated emissions measurements, that is, in locations different from a standard test site, can be a challenging task because of the high electromagnetic noise levels in the ambient. A harsh electromagnetic ... -
Ultra-high input impedance buffer for dry or capacitive electrodes: design and characterization for industry
(Institute of Electrical and Electronics Engineers (IEEE), 2023-07-04)
Article
Accés obertA large number of health and wellness applications wish to monitor electrocardiogram signal (ECG) in the least intrusive way possible. The use of dry textile electrodes with high input impedance bio-amplifiers is a common ... -
Combined femoral and tibial component total knee arthroplasty device rotation measurement is reliable and predicts clinical outcome
(2023-08-03)
Article
Accés obertBackground The optimal total knee arthroplasty (TKA) rotational alignment and how best to obtain and measure it are debatable. The aim was to analyse the reliability of the Berger femoral, three different tibial and four ... -
Charging of free-falling test masses in orbit due to cosmic rays: results from LISA Pathfinder
(American Physical Society, 2023-03-22)
Article
Accés obertA comprehensive summary of the measurements made to characterize test-mass charging due to the space environment during the LISA Pathfinder mission is presented. Measurements of the residual charge of the test mass after ...
