Development study of a capacitance void fraction sensor using asymmetrical electrode plates

Journal of Fluid Science and Technology, 2016
A capacitance-based void fraction sensor has been developed for the rocket or airbreathing engines, which is simple and do not disturb the flow. Typical conventional sensors usually have two concave electrodes mounted on the outer wall of the dielectric ...

Evaluation of Oil-Film Thickness Along the Path of Contact in a Gear Mesh by Capacitance Measurement

Tribology Online, 2016
This paper presents a new method to evaluate the oil-film thickness in gears. By using high speed capacitance measurements in combination with an exact timing it is possible to detect the changes in capacitance along the path of contact.

A Capacitance Build-Up Method to Determine LCR Meter Errors and Capacitance Transfer [PDF]

, 2020
We present a capacitance build-up method suitable for the determination of the measurement error of a capacitance meter. The method requires only a small number of uncalibrated base capacitors, to be connected in parallel in various combinations, and a ...

A 3-Port Network-Based Capacitance Measurement Method for Asymmetric Half-Bridge Power Modules

IEEE Access
This paper proposes a method to measure the capacitance of an asymmetric half-bridge power module using a single 3-port S-parameter measurement. The capacitance of a power module originates from power semiconductors including the package and affects ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Electrical Capacitance Tomography Using Incomplete Measurement Set

IEEE Access, 2019
In the electrical capacitance tomography (ECT) systems, the electrodes, and cables may fail to function properly, which will cause several measurements missing. In these cases, image reconstruction can only use the remaining effective measurements.
