Inductive Rectilinear Frame Dragging and Local Coupling to the Gravitational Field of the Universe

open access: yesUniverse, 2021
There is a drag force on objects moving in the background cosmological metric, known from galaxy cluster dynamics. The force is quite small over laboratory timescales, yet it applies in principle to all moving bodies in the universe.

Corrosion rate determination of rare-earth Mg alloys in a Na2SO4 solution by electrochemical measurements and inductive coupled plasma-optical emission spectroscopy

open access: yesJournal of Magnesium and Alloys, 2019
The corrosion resistance of three Mg alloys containing rare-earth elements (WE43, EV31 and ZE41) was studied and compared to that of two Mg– Al alloys (AZ31 and AZ91) and of pure Mg (99.95 wt.%).

The Reference Wideband Inductive Current Transformer

open access: yesEnergies, 2023
The aim of this paper is to show that the developed inductive current transformer may ensure the required wideband transformation accuracy and it may be applied, as the reference source, in the measuring system for the evaluation of the transformation ...

Foreign Object Detection in Inductive Charging Systems Based on Primary Side Measurements

open access: yesIEEE transactions on industry applications, 2019
A foreign object detection (FOD) method for inductive charging systems is introduced in this article. The proposed FOD only requires primary side measurements, i.e., primary resonant current and resonance frequency deviation.

Magnetic induction pneumography: a planar coil system for continuous monitoring of lung function via contactless measurements

open access: yesJournal of Electrical Bioimpedance, 2010
Continuous monitoring of lung function is of particular interest to the mechanically ventilated patients during critical care. Recent studies have shown that magnetic induction measurements with single coils provide signals which are correlated with the ...

A mathematical description accounting for the superfluous hydrogen evolution and the inductive behaviour observed during electrochemical measurements on magnesium

open access: yesElectrochimica Acta, 2018
When electrochemical techniques are used to probe the surface of corroding magnesium with the aim of obtaining quantitative information on the corrosion process, two peculiarities are generally observed: i) with anodic polarization, the rate of hydrogen ...

Aspects of Foreign Object Detection in a Wireless Charging System for Electric Vehicles Using Passive Inductive Sensors

open access: yesWorld Electric Vehicle Journal, 2022
If the energy transfer for charging the traction battery of an electric vehicle takes place wirelessly and with inductive components, the active area of the charging system must be monitored for safety reasons for the presence or intrusion of metallic ...
