Application of a wireless sensor system for object protection using infrared sensors

Autor: V. I. Parfenov, V. D. Le

Publikováno v: Компьютерная оптика, Vol 45, Iss 3, Pp 364-371 (2021)

In this work, an algorithm that makes decisions on whether or not an object under protection has been penetrated based on data from infrared (IR) sensors included in a wireless sensor system is considered. Based on theoretical considerations, methods

SYNANTROPIZATION FLORA OF PRIPYAT POLESIE AS AN INDICATOR OF ITS ANTHROPOGENIC TRANSFORMATION

Autor: V. I. Parfenov, A. M. Mialik

Publikováno v: Proceedings of the National Academy of Sciences of Belarus, Biological Series. 63:276-285

The article deals with the peculiarities of the synanthropic component of the flora of the Pripyat Polesie – a natural region located in the southern part of Belarus. It is represented by 810 species of vascular plants that can grow in disturbed hu

Algorithms of signal parameter estimation based on the theory of Compressive Sensing and their computer simulation

Autor: V. I. Parfenov, N. A. Kunaeva, D. Y. Golovanov

Publikováno v: Journal of Physics: Conference Series. 1479:012108

The problem of estimating unknown signal parameters in the presence of noise is a classical problem in statistical radio engineering. There are many algorithms for solving this problem. Many of these algorithms are based on the use of well-known stat

Electron scattering on hydrogen and deuterium molecules at 14-25 keV by the 'Troitsk nu-mass' experiment

Autor: G.A. Koroteev, E.V. Geraskin, A. K. Skasyrskaya, V. I. Parfenov, A. A. Nozik, A. I. Belesev, V. Chernov, N. A. Likhovid, A.A. Golubev, V. S. Pantuev, S. V. Zadorozhny, D. N. Abdurashitov

We've performed precise measurements of electron scattering on molecular hydrogen and deuterium by using the "Troitsk nu-mass" setup. Electrons were generated by the electron gun with an energy line width better than 0.3 eV. The electron energies wer
