In this article the methods of diagnosing the patient's condition from biologically active points analyzed, special attention is paid to one of the main problems of contact diagnostic methods, namely, the reliability of diagnostics; the preferred method of measurement, associated with the change in the probe oscillation depending on the change in the load characteristics, is the self-oscillation method. The purpose of the research is to identify the load characteristics corresponding to the best diagnostic reliability. To achieve this goal, the maximum deviation of the established self-oscillator’s frequency is determined for various changes in the load characteristics determined by biologically active points. It considered about the influence of the deviation of the established self-oscillator’s frequency on the reliability of the diagnosis. The result showed that the change in capacitance could be more informative than the change in resistance, which is due to the large value of the dynamic range of the frequency variation of the self-oscillator.

In accordance with the requirements of the legislation of the Russian Federation on the basis of a complex of pros-pecting works, it is necessary to establish the rate of removal of the soil layer. The thickness of the removal of the soil layer is established on the basis of a complex of laboratory studies of soil samples taken from established soil hori-zons. The thickness of the soil horizons is currently determined using stock data based on the characteristic type of soil. However, the thickness of soil horizons in a number of cases on sections characterized by identical soil characteris-tics differ. Thus, in each specific case it is necessary to link the soil sections and boundaries of the selected soil con-tours instrumentally through ecological excavations. High saturation with soil workings can lead to a significant distur-bance of the soil cover of the surveyed area. To solve the above problem, it is proposed to use a unit for studying the power of multicomponent dynamical systems for vertical drilling of soil wells

The article considers the experimental estimation of the heat transfer coefficient in a hybrid immersion cooling system with contact point cooling and dry zones. The change in the heat transfer coefficient is made through a change in the Reynolds number for the flow of the coolant in the immersion cooling system. The experimental investigation is carried out on the basis of a numerical simulation model of the process under study. As a result, the dependences of the thermal resistance of the processor-heat exchanger system on the heat transfer coefficient and on the Reynolds number of the turbulent flow were obtained, and the results with the simulation results were estimated. It is found that, with an increase in the Reynolds number, the heat transfer intensification is weaker than the theoretical one. The refinement coefficients for the case under consideration are found.

In this study, the task is to simulate the cooling system of supercomputers with a heat pump on the reverse Stirling cycle by numerical simulation of heat transfer processes in the object under study. The results of numerical simulation of heat transfer processes in the superheater processor cooling system with a heat pump on the reverse cycle are presented. A numerical model of the heat transfer process was investigated. As a result, the dependencies of the required thermal lift of the heat pump are obtained taking into account the thermal resistance of the system. The first liquid cooling circuit - the cold cylinder of the heat pump and the hot cylinder system - the second liquid cooling circuit, depending on the heat transfer coefficient of the heat pump.

The paper presents the development of a system for detecting the status of control and protection system drives (CPS) of a water-water power reactor by vibration signals using the frequency components method. Results of experimental researches at the "Izhorskiy Plant" PO are given. Spectral analysis is used to isolate the frequency ranges of the CPS diagnostic signal spectra, and to develop diagnostic standards. The work describes formation of reference diagnostic vectors (a set of diagnostic features in the form of a binary code) and their comparison with the current state. The developed standards formed the basis for the system of automatic recognition of the object state. The introduction of such a system will simplify the task of collecting, analyzing, comparing drives data during operation at nuclear power plants, as well as improving methods of testing and diagnosing CPS drives, which should positively affect the reliability and resource of equipment.

The questions of mathematical interpretation of results of trajectory measurements are discussed in terms of increasing the accuracy of identification of bearings of unmanned aerial vehicles during their movement in a "swarm" - a group. Variants of identification of horizontal and spatial bearings are offered. For each of the variants, criteria are proposed for identifying the belonging of the measured values ​​to the same object in the group and the conditions for achieving them. The situation of false positives is shown. It is determined that additional identification measures are needed to eliminate false bearing triads and uncovered ambiguities, including the use of combinatorial exhaustive search algorithms. For their study, it is necessary to develop an experimental statistical model with an algorithmic description of cause-effect relationships, which is a further development of this work.

The problems of studying the mathematical interpretation of the results of trajectory measurements in terms of increasing the accuracy of identification of bearings of unmanned aerial vehicles during their movement in the group "swarm" and "system" are discussed. The variants of identification of horizontal (IHP) and spatial bearings (PPI) are proposed both separately and in a complementary application. Identification of bearings of similar objects in the swarm type group is expedient to be carried out according to the IGP-IPP algorithm. However, it is only partly operational at distances of 3 km or more. As the main algorithm for identifying bearings of similar objects in the "Story" group, it is advisable to use IPP. Although these algorithms achieve high identification efficiency under favorable conditions, with tougher conditions, they drop rather sharply. Therefore, to maintain a high level of probability of "pure" identification, it is advisable to use additional measures to combat false triads. For the removal of problems, it is necessary to develop and apply combinatorial algorithms for exhaustive search, which is the direction for the development of further research.
