“Stealthy” electric current probing technique for power electronics circuits, power device modules and chips makes it possible to measure electric current without any change or disassembling the circuit and the chip connection for the measurement. The technique consists of a tiny-scale magnetic-field coil, a high speed analog amplifier and a digitizer with numerical data processing. This techni...

The capillary electrochromatography (CEC) takes an important position in the separation sciences [1-8], and its further development will contribute to the analytical chemistry field. Therefore the study of the electrochromatographic behavior is very important. The key factor of CEC is the electric field applied along a capillary column. In general, the role of the applied electric field in CEC ...

The paper represents the results of testing effect neutron and gamma radiation radioactive 60Co on electrical filters. Neutron was chosen because its conductivity. analysis standard structure electric filter found that can affect value capacitance as most important component filter. presented are a contribution to wider research resistance elements for coordination insulation at low-voltage lev...

this study presents the electric behavior of sandwich devices based on porous silicon (ps) thin films with au/ps/si/cu structure when the material’s surface is exposed to different gases. ps thin films were fabricated by the electrochemical anodization method of si–c (100) substrates with resistivity 1.4-2.6 ωcm. samples were anodized in a solution of hf (48%), c2h5oh (99.98%) and distilled wat...

the basis of the ohmic heating process is the transmission of alternating electric current through multi-phase solutions that is followed by heat generation due to particle resistance to the transmitted electric current. throughout the present study, simultaneous transfer of heat and electricity was modeled in a two-phase system of solid-liquid food to investigate the critical factors affecting...

The low-voltage operation of a dielectric-barrier-discharge (DBD) plasma actuator with simple electric circuit has the potential to put it into industrial applications. However, there is an issue that efficiency operated DBD lower than high-voltage one. In this study, characteristics silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs), which are used in circuit, i...

Abstract When corona discharge occurs around the wire, it will be accompanied by movement of space charge, and then generate effects such as radio interference audible noise. In order to reveal time domain characteristics electric field generated discharge, a set measurement systems for interference, including oscillator antenna, sampling resistance, data acquisition system, is developed. Based...

A method based on acoustic emission (AE) sensing in which two AE sensors are used to measure the tribological characteristics of interacting friction materials simultaneously real time was assessed for situ measurement and evaluation wear process silver plating. were attached a silver-plated pin plate, signals measured pin-on-plate-type reciprocating sliding tester. The resulting changes signal...
