Theoretical, methodical and practical issues of the ethics of leadership of a modern specialist, its nature, essence and basic principles are considered. The manual contains brief information that allows students to get a general idea of leadership, information about methods of forming leadership qualities of teachers and students, information about startups, as an important component of the future specialist-leader. The manual is intended for students of all majors studying the "Leadership" course, and may also be useful for teachers of psychological, pedagogical and management disciplines.
Information Analysis of Biochemical Parameters for Glucose Tolerance Tests
(Springer Nature Switzerland AG, 2020) Sokol, Yevgen I.; Chmykhova, Oksana V.; Boyko, V. V.; Zamyatin, P. N.; Zamiatin, D. P.
In the vast majority of existing methods of obtaining parametric biomedical information, it is represented by a finite set of informative parameters (features). Their informational significance is always different and practically not evaluated for the tasks of parametric identification and diagnosis of diabetes mellitus. In this paper, it is proposed to evaluate the informational significance of parameters (features) based on dispersion analysis of changes in their mathematical expectation with respect to residual noise. Fisher’s F-statistics were used as a quantitative measure of the changes, with the subsequent conversion of the obtained data into the amount of information expected based on the equations of the information measurement theory.
Improving the Quality of Electrical Energy in the Railway Power Supply System
(Institute of Electrical and Electronics Engineers, 2018) Sokol, Yevgen I.; Zamaruiev, Volodymyr V.; Ivakhno, Volodymyr V.; Styslo, Bohdan O.
The pulsating mode of the power consumption in the railroad power supply network is the cause of the occurrence of voltage pulsations in the contact network. This leads to a decrease in the efficiency of the energy system. To compensate power fluctuations in the electric power supply network of the railway, it is proposed to use hybrid electric energy storage devices. The use of two-channel additional traction power station with an appropriate control system was proposed. The basis of the mathematical model is the data of real measurements.
The Negative Feedback Connection in the Homeostatic System of Carbohydrate Exchange Regulation
(Institute of Electrical and Electronics Engineers, 2018) Sokol, Yevgen I.; Lapta, Stanislav S.; Chmykhova, Oksana V.; Solovyova, Olga I.; Karachntsev, Iurii; Kravchun, Nona; Goncharova, Olga
The article gives a brief overview of the state of solution of an important scientific and applied problem of mathematical modeling of the physiological system of carbohydrate exchange regulation. It shows that for the half of the century all the previous attempts to solve it have been physiologically inadequate. It demonstrates the model that has been proposed a little more than twenty years ago and is yet little known to the scientific community, which is the most minimal model of regulation of carbohydrate exchange in the form of the model of the homeostatic self-regulation of the glycemic level for a single variable of the glycemic state at the periphery. This model is structurally-functional in the form of a differential equation of the first order with a delayed argument. It reproduces - without re-adjusting of its main parameters - universally the glycemic curve of both IVGTT and OGTT, as well as the daily glycemic profile. The internal fundamental difference of this model from all the previous models is ascertained in describing the oscillations of glycemic curves due to the different character of the negative feedback connection with delay: the local and integral aftereffect. For the first time the universal equation of oscillations is proposed in the system with self-regulation, which combines both harmonic and nonharmonic oscillations
Diagnostic Biotechnical System of the Quantitative Diagnostics of Malabsorption
(Institute of Electrical and Electronics Engineers, 2017) Sokol, Yevgen I.; Lapta, Stanislav S.; Chmykhova, Oksana V.; Solovyova, Olga I.; Goncharova, Olga
An algorithmic block of biotechnical system of the quantitative diagnostics of glucose malabsorption on the base of conversion of the oral glucose to lerance test glycemic data into the necessary diagnostical parameters by the use of the original mathematical model of the carbohydrate metabolism regulation system was elaborated. A new diagnostic parameter, characterising a degree of glucose absorption in the intestine, was suggested as well as the criteria on it. Diagnostics on the new parameter was compared with the diagnostics by means of “sugar loads” and “glucose absorption intensity” methods.
Calculation of electric field distribution in the vicinity of power transmission lines with towers and unmanned aerial vehicles presence
(Інститут електродинаміки НАН України, 2018) Rezinkina, M. M.; Sokol, Yevgen I. ; Gryb, O. G.; Bortnikov, A. V.; Lytvynenko, S. A.
The results of mathematical modeling of the electric field of overhead power transmission lines (TL) are presented taking into account presence of towers and unmanned aerial vehicles (UAVs) for various cases of the TL lines layout: vertical, horizontal and triangular. Numerical calculations of electric field (EF) were performed using finite integration technique and uniaxial perfectly matched layer. In this case the TL lines under the electrical potential were replaced by linear charges located on their axes. The obtained numerical results for the case of towers and UAV absence were compared with the analytical solutions, which showed coincidence of the EF strength moduli within the range of the assigned accuracy of the numerical calculations– 3%. The results of calculations are necessary to determine the flight height of UAVs, safe from the point of view of electromagnetic compatibility of the on-board electronics to influence of the TL EF and TL towers.

Electronic phase shifting in multipulse rectifier
(Sciendo, 2017) Sokol, Yevgen I.; Zamaruiev, Volodymyr V.; Ivakhno, Volodymyr V.; Voitovych, Yurii
This paper presents a novel converter which can reduce the harmonics like the conventional multipulse converters with input three phase transformer. To reduce total harmonic distortion of input current and improve the weight and size of converters, it is suggested to use multi-pulse rectifiers with an electronic phase shift. The basic module is a 6-pulse rectifier on fully controlled switches with the reverse blocking ability. Switching frequency either coincides or is twice the power frequency. The proposed solutions allow refusing from the electromagnetic phase-shifting devices (power transformers or auto-transformers) and thereby significantly reduce the weight of the device. Unlike power factor correction systems with high-frequency modulation, the proposed converters are significantly different, as they have better electromagnetic compatibility and the virtual absence of dynamic switching losses of power switches.
AC/DC converter for DC traction power supply system with high-speed train operation
(2019) Sokol, Yevgen I. ; Sychenko, Viktor; Voitovych, Yurii; Kosariev, Yevhen; Styslo, Bohdan; Hubskyi, Petro
Purpose of the work is improved approaches to ensure the required quality parameters of voltage in the traction network based on modern technologies and equipment. The pulsating mode of the power consumption in the railroad power supply network is the cause of the occurrence of voltage pulsations in the contact network. The use of active rectifiers in the electric power supply system of the railroad is proposed. The control system is developed by the converter, which allows to stabilize the output voltage in the DC link and also provides the unit power factor consumed by the converter and the THD consumption current at the level of 8%. A mathematical model of the converter was developed and a study of its main modes of operation was performed.
