Today, the most important component of the mathematical modeling method, which is effectively used to solve modern application problems, is modern information technology, which allows not only to accumulate practically unlimited amounts of experimental information, but also to analyze this data using visualization methods. The article discusses issues related to the development and implementation of a distributed computing system that makes it possible to simulate and analyze multiple experiments for data transmission in the case of using multi-frequency communication sys-tems. Signal models with maximum entropy are used as message source models. As a model of a communication channel with noise, a channel with additive Gaussian noise which has a uniform spectrum in a given frequency band is used. The implemented computing system allows tabular and visual analysis of such parameters of the multiple experiments as the number of signal subcarriers, the range of time interval for signal restoration, the signal-to-noise ratio, the quadrature and in-phase components of the QAM signal, the energy and information characteristics of the signal and the speed of data transmission of the communication channel. The results of the serial experiments are illustrated in form of interactive graphs with animated effects.

The article is devoted to the study of the movement of the inspector satellite in the vicinity of the observed spacecraft. The inspector satellite is developed in order to monitor the spacecraft, carry out timely maintenance in order to eliminate malfunctions for its further functioning, refueling, towing, etc. One of the most important stages of the satellite is the approach to the spacecraft, which is planned by modeling using the equations of relative orbital motion, which generation is presented in this article. The rendezvous procedure is carried out by two-pulse maneuver. The article also describes conducted numerical experiments modeling the approach under different initial conditions, in which conditions for collision and safe approach of the satellite with the spacecraft, the most convenient observation positions near the spacecraft and the time when it can be observed are determined.

This work presents results of the testing of modified pseudorandom signal generators. Two generators developed on the basis of the Lorentz system with chaotic dynamics are considered. The first generator is described by the Lorentz system implemented over a Galois field, and the second is described by the Lorentz system in which digital sequence formation occurs by periodic sampling from signal signatures. As an additional confirmation of the relevance of the results obtained, the article valuates a generator developed on the basis of the standard Matlab function for binary random sequence generating. Generator testing was carried out using a test battery developed by the National Institute of Standards and Technology, which includes 15 different tests. The results obtained are compared with the results obtained by testing reference generators. The results of this research can be applied in the development of cryptographic and data transmission systems.

This article explores and develops innovative approaches to integrating end-to-end technologies into education. End-to-end technologies are fundamentally new technological solutions that permeate all aspects of the educational process, combining curricula, teaching methods and assessment of results together. The purpose of this article is to study and adapt end-to-end technologies in order to increase the effectiveness of education, improve the availability of educational resources, and develop critical thinking and creative skills of students. The article will analyze existing end-to-end technologies and identify the most promising approaches for implementation in the educational process. Practical tools and techniques will be developed based on the use of end-to-end technologies that can be applied in educational institutions at various levels. As part of the study, the authors also pay attention to the aspect of training teaching staff to use end-to-end technologies. It is noted that the integration of these technologies, in addition to technical, also requires pedagogical training.

This paper describes the application of fuzzy perсeptron in acceptance testing problems. A study on the use of various fuzzy functions in solving the problem of approximation of probability densities was carried out. Experiments were conducted on time series with preset distribution laws, evaluating approximation quality using standard deviation in the series of 29 tests. As a result of the research, using Gaussian fuzzy function, the mean value of standard deviation equal to 0.00145 determined which confirms good approximative ability of the fuzzy perсeptron. The system was tested on the acceptance test data of the gas compressor engine. In this case, approximation quality was assessed using the Kolmogorov-Smirnov agreement criterion. Analysis results confirm the high approximative ability of the fuzzy perсeptron, emphasizing its applicability in real acceptance tests.

The usual problem of steganography is to mask an important message in a covering object that is of no interest to the attacker. In this case, attention is paid to protection from detection of the very fact of the message embedding a, since if an attacker suspects the presence of a hidden message in the transmitted information object, he can destroy the message. By the way no attention is paid to reading tolerance in steganography, since it is believed that this issue is solved by preliminary crypto-graphic encryption of the message. However, such encryption affects statistical parameters of the message, which plays an important role in the steganographic system formation. The artiсle is devoted to the analysis of the influence of cryptographic coding on the potential detectability of the message after steganographic masking. The results of the study on the influence of crypto-graphic coding on the transmitted data distribution values when using the «Kuznyechik» cipher are presented.

The article describes analysis of boundary latencies in the TSN Ethernet network using deterministic analysis, based on network calculations. Today Internet networks have successfully reduced end-toend operational latencies to tens of milliseconds only, but modern applications require even lower latencies. It is so caslled ultrashort or edge latency (ULL), that fulfil requirements of modern applications. Latencies are very critical factor in such area as telemedicine because telesurgery needs almost real-time network connection. The article provides results of TSN Ethernet network analysis in the form of a graph.
