electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. electric motors account for between 43 and 46% of all global electricity consumption approximately. they give rise to about 6 040 mt of co2 emissions. end‐users approximately spend usd 565 billion per year on electricity [1]. in recent years, increase in e...

In this paper, we present an RIP module with the features of supporting multiple inductive sensors, no variable frequency LC oscillator, low power consumption, and automatic gain adjustment for each channel. Based on the method of inductance measurement without using a variable frequency LC oscillator, we further integrate pulse amplitude modulation and time division multiplexing scheme into a ...

The application of an electric field to a flame modifies the characteristics due collective motion charged particles generated within flame. applied mobilises electrons and ions depending on their polarity, leading localised regions space charge with sufficient density either locally amplify or shield field. A fundamental understanding local is essential for both electrically plasma-assisted co...

Linear measurement includes the measurement of lengths, diameters, heights and thickness. The basic principle of linear measurement (mechanical type) is that of comparison with standard dimensions on a suitably engraved instrument or device. Linear measuring instruments are categorized depending upon their accuracy. The two categories are non-precision instruments and precision instruments. Non...

We study fluctuations of electric current in a quantum resistor and derive a general quantum-mechanical formula for the distribution of transmitted charge. For that we introduce a scheme of current measurement that involves a spin 1/2 coupled to the current so that it precesses at the rate proportional to the current. Our approach allows the study of charge transfer without breaking the circuit...
