“…In [19], it was proposed to use the generator method to increase the sensitivity and accuracy of humidity measurement of petroleum products. In [20], we proposed different variants of electrical circuits of measuring transducers based on transistor structures with negative differential resistance. A pyroelectric was used in [20] to implement the optical measurement method.…”

“…When performing indirect measurements, the microprocessor system [19]: 1) processes measurement modes automatically in accordance with a specified program, 2) stores the results of direct measurements, 3) performs necessary calculations and displays the physical value measured on a display. Although the measurements are indirect, a user perceives them as direct ones [17][18][19][20].…”

A device with a frequency-modulated output signal has been developed to increase the sensitivity and accuracy of measuring moisture content in crude oil and petroleum products in the range of 0~20%. The main element of the device is a self-oscillator transducer based on a transistor structure with negative differential resistance. A capacitive sensor in the form of a capacitive cylindrical structure with cylindrical electrodes was used to determine moisture content in crude oil and petroleum products. Electric permittivity of a two-component mixture of oil and water was estimated and the capacitance of the humidity-sensitive capacitive cylindrical structure with cylindrical electrodes was calculated. An electrical diagram of the device for measuring and controlling the humidity of crude oil and petroleum products has been developed. The relative error of converting the humidity of oil and petroleum products into capacitance which was caused by the change in oil temperature, was determined to be 0.225%. Values of relative errors of the device for measuring the humidity of oil and petroleum products are as follows: 1.355 • 10 −5 % is caused by instability of the oscillator frequency, 0.01% is caused by fluctuations in the supply voltage of the self-oscillator transducer, 0.05% is caused by a change in ambient temperature by 1 • C. For the developed device, which used errors of the first and second type, the reliability of humidity control of oil and petroleum products has been determined to be 0.9591.

“…compared to p-n junctions obtained by annealing [5]. Although, microelectonic devices are deeply researched and developed [6], available literature does not answer the questions about both the reasons for the improvement of the quality of p-n junctions obtained using ultrasonic processing (ultrasound p-n junctions) and the mechanisms of this phenomenon. But even a superficial comparison of the effects of thermal and ultrasonic treatments in terms of crystal lattice expansion and oscillation intensification is not in favor of ultrasound treatment (more on this below).…”

In this article, mathematical models and processes of introducing homogeneous ultrasonic oscillations and mechanical stresses into silicon wafers in the direction of their thickness are developed and investigated, and mathematical models of the movement of interstitial defects in silicon wafers created by the processes of ion-beam transients at the transitions of ion-beam transitions and hidden dielectric layers using the action of ultrasound oscillations and mechanical stresses, both in the process of implantation of impurities and before the annealing of plates upon activation of the impurities are developed and investigated.
