Informatization in the Digital Economy

The authors conducted a study of the possibility of improving security in educational institutions through the introduction of an intelligent video analytics system. The main components of intelligent video analytics systems are considered; a general algorithm for the operation of such systems is formulated and visualized. The main companies engaged in the development of video analytics systems adapted to various fields and monitoring dangerous situations at important state-owned enterprises in real time are systematized. Examples of the application of systems in various fields allowed the authors to formulate typical steps when deciding on the introduction and implementation of a video analytics system in educational institutions. The main advantages and opportunities are noted. Special attention is paid to the technological risks of introducing digital technology into the field of video stream analysis.

The article provides a complete bifurcation analysis of the mathematical model of the Supply and Demand Dynamic System. Based on the theoretical analysis and numerical experiment in the Matlab+Simulink package, all phase portraits of the system were obtained; and an additive control system for the interaction of supply and demand was built. A class of permissible achievable states of the dynamic system under study is particularized. With the help of the constructed model, it is possible to make a forecast of the development of the process under consideration at any initially specified state of the system.

Recently, non-fungible token (NFT) technology has gained widespread adoption and has become an integral part of the cryptocurrency world. This raises the question of how this technology can be used to develop other industries, such as sports and tourism. In this article, the authors explore the potential of NFTs as a tool for sports and tourism marketing.The study analyzes examples of using NFTs in the sports and tourism industries, as well as the advantages and disadvantages of this technology. The authors identify the main problems that may arise when using NFTs in sports and tourism, such as the complexity of creating and promoting tokens, as well as the need to ensure security and protection against counterfeits.However, despite these challenges, the authors conclude that NFTs in sports and tourism marketing have great potential for attracting new customers and improving interaction with existing ones. For example, creating non-fungible tokens for exclusive tourist routes or sporting events can attract the attention of travel and sports enthusiasts, as well as allow them to gain a unique experience.Thus, NFTs in sports and tourism marketing can be a useful tool for the development of these industries, but further research and technical improvements are required.

There is a problem of processing images of tangential stress fields obtained during the experiment using liquid crystals. These images are complex and may contain a large amount of information that needs to be processed and analyzed. The main problem is the need to extract useful information from such images. This requires special data processing algorithms that can automatically identify areas with tangential stresses of interest. These algorithms can use various methods, such as machine learning, noise filtering and image segmentation. Another problem is the need to analyze the data obtained. Various image analysis and statistical data analysis software can be used for this purpose. Additional experiments may also be required to verify the adequacy of the results obtained and their further interpretation.
