Piecewise linearization of quadratic transfer characteristics
(2022-05-19)
Report de recerca
Accés obertPiecewise linearization replaces a nonlinear transfer characteristic curve by a string of linear segments that connect several calibration points of the curve. This technique can be implemented by low-power digital ... -
Effects of stray capacitance to ground in impedance measurements
(Elsevier, 2021)
Capítol de llibre
Accés restringit per política de l'editorialInductive effects such as positive phase angles in impedance measurements have often confused the researchers when the material measured is nonmagnetic. When the measurement is based on auto-balancing bridge method and the ... -
Basic design of the signal chain in sensor-based measurement systems
(2022-04-19)
Report de recerca
Accés obertSensor signals do not suit direct electronic communication and need further processing before being digitized. Therefore, the requirements of the digitizer add to those needed to fulfill the basic specifications for the ... -
Characterization of time domain EM field double-loaded curved loop probe
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertIn this paper, we present and analyze the performance of a double-loaded curved loop probe to measure simultaneously electric and magnetic fields (EMF). The aim is to construct a probe that can be fitted to non-planar ... -
Magnetic localization system for short-range positioning: a ready-to-use design tool
(2021)
Article
Accés obertMagnetic localization is used in many indoor positioning applications, such as industrial, medical, and IoT, for its benefits related to the absence of line of sight needs, multipath and fading, the low cost of transmitters ... -
Non-contact video-based assessment of the respiratory function using a RGB-D camera
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-20)
Article
Accés obertA fully automatic, non-contact method for the assessment of the respiratory function is proposed using an RGB-D camera-based technology. The proposed algorithm relies on the depth channel of the camera to estimate the ... -
Entropy generation model to estimate battery ageing
(Elsevier, 2020-12)
Article
Accés obertDetermining battery ageing is a key issue in predicting the available charge in battery-operated systems. Beyond the common use of voltage or current measurements, which have proved unsuccessful as general methods, we aim ... -
Hydrophobic membranes for ammonia recovery from digestates in microbial electrolysis cells: Assessment of different configurations
(Elsevier, 2021-08)
Article
Accés obertThe combination of hydrophobic membranes and microbial electrolysis cells (MEC) was assessed in two different configurations in order to recover ammonia from anaerobically digested pig slurry. Politetrafluorethilene ... -
Analysis of energy and entropy balance in a residential building
(2022-01-20)
Article
Accés obertThe energy performance of a building located in La Roca del Vallès, close to Barcelona in Spain designed under the near Zero Energy Building (nZEB) and Net Zero Energy Building (NZEB) criteria was investigated. The aim was ... -
Common mode response effects in differential measurements
(2021-01)
Article
Accés obertDifferential measurements yield signals that are conditioned by differential or fully differential circuits which output depends on both the differential- and common-mode input voltages. Differential signals carry the ... -
Sedimentation monitoring of the active biomass in bioreactors by electrical impedance spectroscopy
(2020)
Text en actes de congrés
Accés obertSequencing batch reactors are used in wastewater treatment to produce biogas (methane). Currently, when biogas production ceases the active sludge sedimentation process is not monitored but operated on a fixed time basis. ...
