This article describes a developed method for automatically optimizing the parameters of an intelligent controller based on an adaptive genetic algorithm. The key goal of this development is to improve the mechanism for generating an intelligent controller rule base through multiparameter optimization. The genetic algorithm is used to eliminate linguistic uncertainty in the design of control systems based on intelligent controllers. A unique algorithm is proposed that implements a comprehensive optimization procedure structured in three sequential stages: identifying optimal control system parameters, optimizing the structure of the intelligent controller rule base, simulating the automatic generation process, and then optimizing the intelligent controller parameters. Implementation of this approach optimizes the weights of fuzzy logic rules and the centers of the membership functions of linguistic variables.

The article presents a basic model for information support of decision-making designed to enhance the efficiency and resilience of organizational systems within the information security units of the Russian Ministry of Emergency Situations (EMERCOM). The model constitutes an integrated, multi-level system based on the interaction of five interrelated mathematical models: data collection and preprocessing, automated classification, situation forecasting and analysis, decision option generation, and knowledge management. To enhance the model’s functionality and adaptability under conditions of uncertainty, the following formulas have been introduced: assessment of data processing system workload; automatic calibration of weighting coefficients based on forecast error minimization; calculation of information source credibility index; weighted event evaluation accounting for source credibility; decision explainability using the SHAP method; and knowledge utility metrics together with criteria for knowledge archiving. These formulas ensure objectivity, transparency, and robustness of management processes, enabling rapid response to cyber threats, minimizing the impact of human factors, and maintaining high-quality managerial decision-making.

Choosing the best video compression method is becoming increasingly important as the volume of online video grows rapidly. By 2026, people are predicted to watch 82% more video online than in 2020. This means finding a balance between image quality, processing speed, and file size. To achieve the desired parameters, it's crucial to choose the right codec.
This paper compares five popular codecs—MPEG-2, MPEG-4, VP9, ​​MJPEG, and ProRes. Each codec offers its own unique method for compressing video, yielding different file sizes and image quality. The goal was to determine which codec is best suited for various applications: video calls, professional filming, and online broadcasts.
The experiments were conducted on a server with four processor cores, 8 GB of RAM, and an 80 GB SSD. Measurements were taken to determine the speed of each codec, the resulting file size, and the video quality. Based on the results of these tests, recommendations were made on which codec to choose and how it can be improved in different scenarios.

This article discusses an approach to the development of a control and accounting system for the target mixture loaded into glass furnaces located in machine shops of both a single plant and a group of glass plants belonging to one enterprise. A structural scheme is proposed for organizing the collection, processing and storage of data obtained from weight indicators of various models that support their own network frame formats. As an example, a network scheme for the implementation of the designated control and accounting system for target mixtures is demonstrated, applied to two geographically remote glass factories, using a mechanism for building private networks on top of open and public communication channels. The effectiveness of the proposed approaches to the organization of operational control over the volumes of loading of the target mixture into glass furnaces is substantiated, as well as the expediency of using this solution

In reinforced concrete design standards, the values of concrete strain are taken as average values, whereas the strength characteristics are adopted with a high level of reliability. In the ultimate force method for calculating reinforced concrete structures, the strains of concrete and reinforcement are not directly used in the governing equations. In calculations based on the nonlinear deformation model, the strain values are directly used in the analysis. Using average values of the ultimate strains of concrete reduces the reliability of the obtained results. This study examines the influence of the variability of deformation characteristics of concrete and reinforcement on the load-bearing capacity of eccentrically compressed reinforced concrete elements. It was found that the variability of the deformation characteristics of concrete and reinforcement significantly affects the load-bearing capacity of eccentrically compressed reinforced concrete elements. This influence increases with the reinforcement ratio and depends on the eccentricity of the applied axial force. The reliability and safety of eccentrically compressed reinforced concrete elements decrease significantly when average values of the deformation characteristics of concrete and reinforcement are used in calculations.

The purpose of the article: to determine the possibility of using file hash analysis using artificial neural networks to detect exploits in files. Research method: the search for exploits in files is carried out based on the analysis of Windows registry file hashes obtained by two hashing algorithms SHA-256 and SHA-512, using three types of artificial neural networks (direct propagation, recurrent, convolutional). The obtained result: the use of artificial neural networks in file hash analysis allows us to identify exploits or malicious records in files; the performance (accuracy) of artificial neural networks of direct propagation and with recurrent architecture are comparable to each other and are much more productive than convolutional neural networks; the longer the length of the file hash, the more reliably it is to identify an exploit in the file

A protective coating based on carboxymethylcellulose and zinc powder has been developed. It was established that the incorporation of zinc and the plasticizer glycerol into the polymer matrix leads to an increase in adhesion and mechanical strength of the coatings—from 5.1 MPa to 15.5 MPa and from grade 4 to grade 0, respectively. The morphology of the coating was examined using optical microscopy. It was shown that zinc particles are relatively uniformly distributed within the polymer matrix, and their aggregation decreases upon glycerol addition. Digital images of the coatings were used to quantitatively evaluate the fraction of zinc particles located at the coating–substrate interface. Due to particle sedimentation, the particle fraction at the interface exceeds that on the surface by 10–20%, which improves the coating’s adhesion to the substrate. The coating was found to be resistant to acidic and alkaline media, organic solvents, and alcohols.

The article examines a functional-dynamic model of implementing intelligent digital platforms and solutions, whose governing role in the development of a macroeconomic system is taken into account using a feedback mechanism. The relevance of the study is demonstrated in the context of active digital transformation of industries. The mathematical form of the model under consideration is a system of nonlinear differential equations of an evolutionary type, similar to dynamic models of the development of biological communities. An analysis of a macrosystem influenced by innovative technologies is carried out. As such a system, a two-sector macrostructure is considered, simulating the impact through the implementation and use of intelligent digital platforms (IDP) of two related industries, which are the transport and logistics and manufacturing sectors. The objective of the work is to study the stable states of such a structure. The model allows for taking into account the influence of investments in IDPs based on the principle of their proportionality to the growth rates of return on assets in these industries. In the work, quantitative estimates of the parameters of the original model are adjusted. An analysis of the macrosystem is carried out under conditions of different development rates of the interacting industries. The stability of the system according to Lyapunov is studied. An asymptotic approximation ‒ a solution to the problem ‒ was constructed using A.B. Vasil’eva's boundary layer decomposition method. The results describe the process of self-organization in a stable model of interaction between two related industries, supported by integrated digital platforms.

As a result of changes in regulatory documents on acceptance of residential premises, there is a need to develop illustrative methodological materials that would allow the future owner to independently, i.e. without the involvement of an external qualified specialist, to perform the acceptance of the apartment, pointing out to the representative of the developer involved in the acceptance of significant construction defects. The purpose of the study is to determine the structure of construction defects in residential premises and to identify the most common defects in this structure, which will allow the future owner to independently perform the acceptance of the apartment. In the article, based on the analysis of a significant number of claims from apartment owners to the builder and the results of the authors' research in the scope of forensic examinations and pre-trial construction-technical investigations, the structure of construction defects, which are massively identified in the process of acceptance of apartments, is defined and presented. The groups of defects that are most frequently encountered in practice are presented.

A brief list of problems in the operational reliability of multilayer energy-saving walls is given, and the thesis is formulated that single-layer or equal-permeability multilayer walls may have better operational properties. Information about the equipment and technology for producing foam concrete mixtures using a one-stage method is provided. It is shown that the introduction of a fibrous filler instead of some of the sand significantly accelerates the phase transition of the mixtures from a viscous state to an elastic state and has a positive effect on the operational properties of the hardened foam concrete. The list of the material's investigated performance properties includes experimentally obtained indicators of sorption properties, equilibrium moisture content, thermal conductivity, and frost resistance of thermal insulation and structural-thermal insulation foam concrete containing different amounts of fibers of different lengths.
