Optical transducers with frequency output
(SPIE, 2017)
In this work the characteristics research of microelectronic transducers of optical radiation with a frequency output signal on the basis of a hybrid integrated circuit consisting of a bipolar and a field-effect transistor ...
One example of exactly solvable quantum mechanics problem of position dependent mass
(Taras Shevchenko National University of Kyiv, 2017)
This communication has been dedicated to quantum dynamics of particle whose mass depends on coordinate. We considered one dimensional model which admits to obtain the exact solution of wave equation. The position dependent ...
Optimal Determination Method of the Transposition Steps of An Extra-High Voltage Power Transmission Line
(Multidisciplinary Digital Publishing Institute, 2021)
During the design of extra-high-voltage transmission lines, studies of the influence of
asymmetry due to the phase difference of the parameters on its processes and the electrical network
were performed. To compensate ...
Oranization-Managerial Mechanism of the Couneraction to Non-Observable Economic Processes in the Agricultural Sphere of Ukraine.
(Springer, 2020)
The paper substantiates the author’s approach to the problem of the counteraction to nonobservable economic processes in the agricultural sphere of Ukraine. The approach is based on the monitoring of
the actions of the ...
Optical-frequency gas flow meter on the basis of transistor structures with negative differential resistance
(SPIE, 2020)
The article investigated the optical-frequency gas flow meter based on a transistor structure with negative differential resistance (NDR). A schematic diagram and design of an optical-frequency gas flow transducer that ...
Electronic structure and properties of apatite-like calcium-based compounds, initiated by nanodimemsion, biogenic factor and isomorphic substitution of calcium by 3d-metalls
(Publishing house "Internauka", 2021)
Calcium apatites due to their physicochemical properties, high biological activity deservedly attract special attention
not only in view of purely scientific interest, but also in connection with the use of drugs synthesized ...
