An online tail breaking force measurement method is developed with a proximity sensor between wire clamp and horn. The wire under the tensile load measures about 1.5 cm extending from the bond location to the wire clamp. To increase the sensitivity, the bondhead speed is reduced to 2mm/s during breaking the tail bond. It takes roughly 10ms to break the tail bond. The force resolution of the met...

The efficiency of transmitting electrical energy from tree phase source is very complicated and expensive. In the same time, it known that active transmitted a to load does not come back source. If this so, then why in all devices systems for transmission electricity, one uses more than wire? “It shown any system can be made using one-wire method”. main results were received by several inventio...

background catheterization of central veins is a routine technique which is widely used in general hospitals and medical intensive care units. it should be carefully performed and managed to prevent adverse side effects. case presentation in this case report, we describe a case of lost guide wire during central venous catheterization, which was successfully treated with a minimally invasive sur...

A bend in a single-conductor line is primary cause of radiation associated with the antenna mode; conversely, fed back, resulting attenuation and distortion current waveform. Despite being fundamental phenomenon, its dynamics have not been sufficiently characterized. Therefore, this study presents transmission-line model for bent wire structures comprising multiple straight elements by using lo...

Heating of chromatographic columns, transfer lines, and other devices is often required in neuroscience research. For example, volatile compounds passing through a capillary column of a gas chromatograph (GC) can be split, with half exiting the instrument through a heated transfer line to an insect antenna or olfactory sensillum for electroantennographic detector (GC-EAD) recordings. The heated...

This paper presents the protective effects of shield wire coupled with Metal Oxide Varistor (MOV) arresters in a distribution network located in a severe lightning area. The presented test case is the IEEE 34-node radial distribution test feeder injected with multiple lightning strokes and simulated with the Alternative Transients Program/ Electromagnetic Transients program (ATP/EMTP). The resp...

The paper presents comparison between two approximate models of energized horizontal thin-wire conductors above two-layer soil. The formulation is posed in frequency domain by using two approaches. The first one is based on quasi-static image theory within Mixed Potential Integral Equation. The second one is based on transmission line theory with approximation of per unit length parameters. The...
