Electronics is the most capacious and rapidly developing industry in our country. Modern methods of designing electronic devices are unthinkable without the use of computer technology, in particular, specialized programs for computer analysis and modeling of circuit diagrams of the devices being developed. Intelligence is the key link in electronics at the present stage of its development. This is due to the emergence and widespread adoption of microcircuits such as microcontrollers. This aspect provides fundamentally new opportunities for solving a wide variety of tasks, including tasks of a strategic orientation that require prompt solutions. All this became possible primarily because devices based on a microcontroller require algorithmic and further software, which makes it possible to create intelligent systems and devices. One such device will be discussed in this article. The developed device is a system consisting directly of a control system, an actuating device, which is a decision-making device, a power unit and peripheral devices. The article explains the idea, the principle of operation of the developed device, the structural and schematic diagrams of the developed main blocks of the device, as well as their algorithmic support, which is based on the principle of intelligent control. The developed device is designed to automatically maintain the level of illumination at the level set by the operator in the premises of industrial enterprises.

The problem of flexible vibrations of a rectangular orthotorque plate clamped along the contour is considered. The general solution of the problem, which satisfies the vibartion equation identically, is constructed on the basis of the superposition method in the form of two Fourier series. Clamped boundary conditions lead to a homogeneous infinite system of linear algebraic equations with respect to unknown coefficients in the general solution. The uniqueness of a bounded non-trivial solution of an infinite system for the natural frequency is proved, the asymptotics of the unknowns are found, and an effective solution algorithm is constructed. Examples of the numerical implementation of the developed algorithm for calculating the natural frequencies and natural modes of the plate vibrations are given.

The growing popularity of the use of group robotics, including swarm robotic systems (SRS), actualizes the issues of information security. Known approaches to detecting malicious behavior of agents or malicious information do not take into account the scalability and decentralization properties of SRS, which does not allow ensuring the integrity of information circulating through communication channels within SRS. In turn, the dissemination of malicious information in the process of distributing tasks between SRS agents initially reduces the efficiency of performing these tasks, that is, an attack is carried out on the very first and most critical stage of the system's functioning. The purpose of this work is to improve the efficiency of the functioning of SRS agents in the presence of malicious agents by developing a method for detecting and counteracting the spread of malicious information. The elements of scientific novelty of this work include the following. As part of solving the problem, a number of specific criteria are proposed that take into account the distribution of tasks in the SRS, as well as a classifier based on an artificial neural network to detect malicious information. To improve the accuracy of detection and counteracting the spread of malicious information in SRS, a modification of the reputation mechanism is proposed. A distinctive feature of the modification is not only the formation of an indicator of the truth of the message information in the process of task distribution, but also the assessment of the influence of malicious agents on the process of forming this indicator. The presented solution is implemented in the form of software in the Python programming language, which can be used in modeling decentralized control systems of SRS.

The article considers the possibilities of using a large fraction of coal industry enrichment waste in road construction. The use of waste rock as a large aggregate in the composition of road concrete is proposed, because the enrichment waste is not disposed of properly, but is sent to the tailings dump. These dumps occupy large areas of land, thereby causing damage to the environment. The fractional composition of coal waste from the enrichment of the Gukovo-Zverevsky coal-bearing area is analyzed. From the results of sieving, it was seen that the structural composition satisfies the size of the fractions of a large aggregate for the concrete mixture. Analytical studies of the composition of the concrete coating were carried out. Based on the analysis of the composition of the concrete mixture, we came to the conclusion that tailings waste can be used as a major substitute. A comparative characteristic of the requirements put forward for the resulting mixture is presented. In our work, one of the main qualities of the road concrete pavement was tested - strength. The results of experimental strength tests of control samples of concrete with various types of aggregate are presented. Based on the results obtained, it is possible to draw a positive conclusion about the possibility of using enrichment waste as a large aggregate of concrete mixture in road construction according to technical and economic criteria.

The results of studies of the effect of mineral additives of natural and man-made origin on some properties of fine-aggregate concrete with the introduction of a mineral additive from 10 to 25% of the cement weight instead of either a part of cement with an increase in the value of W/ C, or a part of sand with a constant value of the value of W / C are presented. A slight, up to 3%, change in the average density of concrete was revealed. A decrease in the E-modulus from 4 to 14% was recorded when replacing a part of cement, while an increase in the flexural strength, depending on the dosage, was up to 26% (marshallite) and 6% (chemical water treatment sludge), and a decrease in the compressive strength was from 10 to 22%. When replacing part of the sand, an increase of up to 10% of the E-modulus, the flexural strength from 19 to 38% (marshallite) and up to 11% (chemical water treatment sludge) was recorded. The increase in the compressive strength, depending on the type and dosage of the additive, ranged from 8 to 20%. No significant effect of additives on the porosity of cement stone was revealed.

The exploited roof is intended for use, for example, as a recreation area, sports grounds, landscaping, parking lots, etc. It is proposed to compensate for the shortage of urban areas and the high cost of land within the city by using the concept of vertical construction expansion. The lack of free open space limits the ability to accommodate the necessary infrastructure to serve the growing number of residents and reduces the level of comfort for living. The article presents the results of a comparative study of technologies for the installation of operated roofs, arranged with a traditional and inverse arrangement of a waterproofing carpet and thermal insulation. As a result of the study, the technological advantages of the installation of an inverted exploitable roof intended for landscaping are shown. The labour intensity of technological operations and the duration of work when installing a green roof using inversion technology is 19.5% lower compared to the traditional one.
