This article discusses the issues of modeling and calculating thermal processes in the human thermoregulation system, taking into account internal sources and heat transfer between the calculated elements and layers. The method of calculating the combined heat exchange processes allow obtaining local thermophysical parameters of the system. The model takes into account the thermal resistance of passive and active thermal protection, the thermophysical and geometric properties of the design elements when the environmental parameters change. To calculate the mass flow rate of the coolant (blood) to the calculated elements, the flow-pressure characteristics of the human circulatory system are taken into account within the framework of the presented methodology. This paper presents the results of model studies of thermal processes in the human thermoregulation system when entering the conditions of weightlessness. The influence of heat transfer with the heat carrier current between the calculated elements and layers on the Earth and in weightlessness is estimated. The influence of the magnitude of internal heat release on the heat exchange processes is investigated. The analysis of the obtained results makes it possible to supplement the experiments with computer studies, as well as to optimize control systems and elements of individual life support systems to protect a person from adverse external factors.

The article presents a comparison of the author's implementation of the Apriori algorithm with implementation presented in the Accord.NET library. A comparison of various parallel implementations of this algorithm is also shown. The main objective of the article is evaluating the efficiency of the Apriori affinity analysis algorithm implementation by the speed of creating an association rules list. The results of testing on the data provided by the company “FB Consult” are given. The test results show an increase in performance of the optimized parallelized implementation by about 5.28 times compared to the implementation from Accord.NET. This article clearly shows that optimization of the algorithm in order to reduce the running time by using binary vectors and operations on them gives more significant speedup than parallelization. Whereas when parallelizing, attention should be paid to the computation of support for association rules, because based on the results of this function, most of the association rules will be eliminated.

Lightning strokes are considered to be the one of the most serious factor impacting the electrical equipment insulation and leading to the high overvoltage level that has to be reduced. The paper deals with the analysis of unrestricted lightning overvoltages impacting the 35-kV cable line insulation that was carried out for the case when the chopped impulse is formed as a result of the line insulation flashover. Following the preliminary results, dangerous lightning overvoltages that exceed the permitted impulse strength of the cable line insulation can occur when the overhead line with the 35-kV nominal voltage is arranged in a 110-kV line frame. In some cases, the traditional protection devices are not effective in the high-frequency overvoltage restriction. So the new method of suppression is considered for the 35-kV cable line protection. The effectiveness of the frequency-dependent device at lightning strokes is analyzed for different simulation modes and variable protection device characteristics. As a result, recommendations for the appropriate frequency-dependent device parameters are given.

Using the fiber-optic communication lines as a guide medium for access networks makes it possible to provide broadband communications, which is necessary in the digital economy. Along with such an indicator of the quality of communication as the speed of information transmission, reliability indicators are widely used. The article discusses the influence of the testing time interval on reliability indicators during periodic predictive monitoring of the fiber-optic communication line state. In particular, the influence of the control period interval and the testing time interval on the unavailability factor of the fiber-optic communication link is investigated. In this case, models of Markov and semi-Markov processes are used to describe the state of the optical line in time. The expressions that allow estimating the optimal ratio between the control period and the testing time on the period that provides the required level of the reliability indicator of the fiber-optic communication link are given.

This paper presents a comparative evaluation of two different algorithms for an Energy Storage System installed with an Engine Generation Set in an autonomous power supply system. The algorithms presented are intended to improve dynamic of the engine generation set units when a load connects or disconnects from the power supply system. All the algorithms are based on the instantaneous power theory. The main advantage of these algorithms is that they do not require any significant changes or additions to the known control system for a shunt active power filter. In fact, as shown in the article, energy storage system controlled by slightly modified algorithm based on the instantaneous power theory becomes a power system for load transients during load commutations. It is shown, that ESS provides smoother power variation using these additions to the conventional instantaneous power theory as far as active power filtering. Moreover, an ESS still may operate as an active power filter with some limitations concerning load changes. The results presented in paper are verified by simulation models.

An approach to modeling multiphase flow of a gas-liquid compressible mixture taking into account the liberation and dissolution of gas is considered. Approach is based on an implicit pressure calculation using the finite element method and explicit phase transport. A computational scheme for modeling the processes of gas component transfer between oil and gas phases based on the known pressure dependence of the gas factor is described. In the considered approach the changes of phases volume appearing during the flow process are taken into account in the right-hand side of the equation used for pressure calculation. An iterative method for solving the obtained nonlinear boundary value problem for pressure calculation is described. This method based on the linearization of the pressure dependence of phases volume changes in the right-hand sides of the equation and boundary conditions. The verification of the proposed method is carried out on a test problem from the comparative project SPE-1. At each time step it takes an average of two nonlinearity iterations. The resulting plots of well data and gas phase distribution data are in good agreement with the results of the SPE-1 project participants.

The dynamics of the development of systems with polarization processing raises the question of the methods of their research. An important role in the creation and research of radio engineering systems is played by methods of semi-natural modeling, which allow conducting research and testing algorithms for the functioning of products at all stages of their development on prototypes and simulators, replacing a significant part of field tests with semi-natural modeling. The combination of full-scale and mathematical models allows us to conduct research of those situations when a full-scale experiment is not possible or its implementation requires the involvement of large resources. One of the measured parameters is noise immunity and stealth. The article presents the basics of the methodology for experimental evaluation of noise immunity and stealth of systems with polarization modulation. The structure of the stand implementing it is described, an example of using the method for comparative evaluation of noise immunity of various processing algorithms is given.

Let there is an image with some object made up of hexagons (for example, a photo of a microchannel plate). In this paper, the algorithm that builds a hexagonal grid on a photo of an object is considered. The main principle of the algorithm is detection the contour of the object. Then with the help of special geometric construction determine the coordinates of each nodal point of the hexagonal grid. The developed algorithm consists of several stages: the detection of the object edge, the corners detection on a two-dimensional curve, geometric constructions for determining the nodal points coordinates. At the same time, the widespread problem of edge detection in this case has a certain specificity. As a result of which a special algorithm for contour selection for this particular task was developed. The algorithm was also tested in conditions of high noise and uneven illumination of the object.

The vector boundary element method is a tool applied to solve electromagnetic problems in a media for which eddy currents must be taken into account. It's also known as the boundary element method for eddy current problems. The use of this method brings certain difficulties, one of which is the problem of zero wave number in the subdomains adjacent to the domain where the eddy currents should be considered. To mitigate the computational difficulty, we use the coupling with the scalar potential. The scalar boundary element method for the Laplace equation is in use for the corresponding adjacent subdomains with zero wave number and the associated scalar potential. In this paper, we present the system of variational equations written in a weak form and based on the Steklov-Poincare operators formulated for both scalar and vector boundary element methods. This coupling is supported with a simple test problem considering a conducting cube and a time-harmonic source of electromagnetic field.
