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.

E. coli belongs to gram-negative rod-shaped bacteria of the Enterobacteriaceae family of facultative anaerobes. It is the most famous microbe in the world and has different types of strains. Commensal E.coli are harmless and often found in nature. Currently, great attention is paid to the use of modified E.coli for the production of recombinant proteins, amino acids. The results of mathematical modeling of the automated system are presented. The simulation was performed using SimInTech and MathCAD software tools. The object of management is the cultivation capacity.

With the development of industry and science, the size of the patent base is growing, as well as the number of patent applications received by the agencies regulating the issue of patents is growing. Each patent application must be checked for the uniqueness of the patented technology, for this, the patent office experts need to search the patent database and find analog patents. In the absence of analog patents, this technology can be considered unique and accepted for patenting. Since the patent database of various departments can number tens of millions of patents, such a patent search and evaluation of the uniqueness of the patented technology can take a very long time. The existing systems do not meet all the requirements and do not have the full necessary functionality. This article describes the development of an automated system for searching for analog patents in the patent array.

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.

This paper describes the issue of choosing a distributed registry platform when designing information systems in the financial sector of the economy. The relevance of these studies is due to the ever-increasing growth in demand for information systems of the financial sector of the economy formed using distributed registry technology. The growing interest in this technology is associated with the need to ensure reliable storage of information, the change of which will be monitored by the participants of this transaction. The purpose of this work is to determine the most suitable platform using the hierarchy analysis method. In the course of the work, the main platforms of the distributed registry were identified, as well as the key criteria for these frameworks were determined, taking into account the requirements of business process participants. These criteria were evaluated. For each alternative evaluation matrix, the indicators of the maximum eigenvalue vector were determined according to separate criteria, and the consistency of the judgment was proved, including the determination of the consistency index, the local priority index and the consistency ratio. A synthetic analysis of the criteria under consideration was carried out. Based on the data obtained during the synthetic analysis, the most promising platform was selected. Conclusions on the evaluated systems are formed.

The paper considers the results of modeling the cable system of the above-water cable-stayed transition of the main gas pipeline using a laboratory installation and computer modeling using finite element methods. The main characteristics of materials and structural elements used to create a computer and laboratory model are given. Various modes of tension of the cable system affecting the further operation of the model under consideration, allowing to determine the service life of the object, are studied. It is shown that with a slight weakening of the tension of one of the cables, in the cable system, the occurrence of stresses in the pipe body is observed, the magnitude of which, under certain conditions, greatly exceeds the operating values. A small imbalance of effort leads to a redistribution of effort and a distortion of the entire structure, which, under cyclic loads, can lead to a premature exit from the standing of the object in question.

In the article, the object of the study is the spread of pollutants from the sources of their release. During the calculations, the sources of atmospheric pollution were combined with the allocation of groups taking into account the height of the mouth of the emission source. To reduce time-consuming calculations using the method of combining sources of atmospheric pollution, the program has been created that provides fast processing of a large amount of information. A data bank on the main sources of pollution of the Rostov region has been compiled; systematization and reduction of these sources to a single coordinate system has been carried out. A trial estimation calculation of the regional transport of pollutants from the combined sources of emissions with the construction of maps of pollution isolines was made.
