Four-point probe measurements using current probes with voltage feedback to measure electric potentials

, 2017
We present a four-point probe resistance measurement technique which uses four equivalent current measuring units, resulting in minimal hardware requirements and corresponding sources of noise.

Statistical Behavior of PMU Measurement Errors: An Experimental Characterization

IEEE Open Journal of Instrumentation and Measurement, 2022
Different power system applications based on synchrophasors measured in different nodes of the electric grid require information about the statistical distribution of the errors introduced by the phasor measurement units (PMUs).

Probe-configuration dependent dephasing in a mesoscopic interferometer

, 2003
Dephasing in a ballistic four-terminal Aharonov-Bohm geometry due to charge and voltage fluctuations is investigated. Treating two terminals as voltage probes, we find a strong dependence of the dephasing rate on the probe configuration in agreement with

Electric signature of magnetic domain-wall dynamics [PDF]

, 2011
We study current-induced domain-wall dynamics in a thin ferromagnetic nanowire. The domain-wall dynamics is described by simple equations with four parameters.

Optimal choice of the number of even harmonics demodulated from the excitation current of a sensor for precise dc voltage component detection in low voltage distributive grid as a strategy for suppression of the systematic error due to the grid voltage fluctuation [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2018
This paper addresses the problem of suppression of a systematic measurement error during the detection of a parasitic DC voltage component, superimposed to an AC voltage. As a sensor the toroidal transformer is employed.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
