The article is devoted to the analysis and optimization of the stability of engineering structures to wind loads through the use of innovative structures of support and anchor foundations. In modern construction, when the requirements for reliability and stability of buildings have increased, special attention is being paid to the development of effective foundations capable of withstanding both compressive and pulling loads. Support and anchor foundations are presented as a comprehensive solution, including combined anchors and a monolithic slab (grillwork), ensuring uniform load distribution. The main focus is on the combined anchor, which acts as the main working element that receives the forces from the structure and effectively transfers them to the ground. Unlike traditional piles, the proposed design significantly increases the resistance to pulling due to the use of wire anchors with high load-bearing capacity.

Steel hoisting ropes play an important role in metallurgical equipment, ensuring reliability and efficiency of lifting operations. One of the key features of their operation is the high level of contamination typical of metallurgical operations. Metallurgical processes are often accompanied by dust, metal chips and other abrasive particles that can significantly degrade ropes, causing wear and corrosion. To maintain the efficient operation of equipment it is necessary to monitor the condition of hoisting ropes in real time, which makes the task of improving automatic systems for monitoring the condition of ropes urgent. The paper reviews the methods of optical control of defects in hoisting steel ropes, the advantages and limitations of different approaches are considered. The aim of the work is to justify the effectiveness of the authors' developed method of analyzing rope defect images using neural networks in relation to the method based on the discrete Fourier transform. It is revealed that one of the most promising in terms of technical and economic efficiency of inspection methods is the application of vision system with image processing based on convolutional neural network technology, which allows to effectively detect defects in complex and changing operating conditions, such as metallurgical and mining production, where the background of the image may be non-uniform, and the distance between the camera and the rope varies.

The article deals with thea comparative analysis of frost resistance assessment results obtained from dry building mixes containing redispersible polymer powders and finely dispersed fillers of natural and technogenic origin, building mortars according to such freeze-thaw resistance criteria as change in ultrasound velocity and dynamic modulus of elasticity, compressive and flexural strength, and adhesion strength to concrete base. The composition of the mixtures is represented by the component ratio C:P:MD = 1:1.3:0.2 at W/C = 0.4. The number of freeze-thaw cycles implemented for the studied compositions, depending on the dosage of redispersible polymer powders, ranged from 100 to 125. Ffreeze-thaw resistance of the studied solutions is not exhausted according to the main standardized criteria. A positive effect of RPP on the freeze-thaw resistance of the contact zone is noted. The most “rigorous” criterion is the flexural strength.

With the development of low-orbit satellite Internet systems (NSIS), issues of ensuring effective operation in conditions of intentional interference come to the fore. One of the solutions is related to the use of systems using both OFDM methods and generators implementing frequency hopping (HF). Obviously, the more complex the algorithm for selecting operating frequencies, the more efficient the operation of the microwave. In the article, it is proposed to use the SPN cipher "Grasshopper" as a generator for selecting operating frequencies. As a result, the CCF system will have a high resistance to calculating operating frequency numbers by electronic warfare systems. However, failures and failures may occur during the operation of the SSC. To prevent their consequences, it is proposed to implement an SPN cipher using polynomial modular codes of residue classes (PMCC). One of the transformations in the "Grasshopper" is a nonlinear transformation that performs the substitution operation. It is obvious that the creation of a new mathematical model for performing a nonlinear transformation using MCCS will ensure the operation of the SPN-cipher-based RF generator in conditions of failures and failures.

When selecting technology options for additive manufacturing, it is important to be guided by a list of basic requirements for manufactured parts, powder material features, and the range of equipment specifications. To develop the most effective solution, pilot testing of the technology will be required to determine the preferred process modes that ensure the required quality, cost, and manufacturing time. Accordingly, for such industries, it is important to develop a model that describes the stages of additive manufacturing. In this regard, this paper is devoted to considering the issues of optimization, planning, and management of additive manufacturing technology based on multiple criteria for selecting the most effective technology that involves optimal loading of production facilities. The proposed model introduces indicators that characterize adaptation and allow arguing the practical benefits of using 3D printing technologies. Comparison of process routes by these indicators allows choosing a specific manufacturing route. Having selected the manufacturing option, it is possible to calculate the most efficient placement of products on platforms, as well as to develop a suitable sequence of execution of the main manufacturing operations in order to minimize costs and time expenditures. It was found that the use of the proposed model allows to reduce the manufacturing time of a batch of products by approximately 2.5%. Thus, the proposed model can be useful in additive manufacturing to reduce downtime of installations and speed up the release of products.

An integrated information security system combining dynamism and efficiency is proposed, and a quantitative assessment of this system is presented. The study is aimed at identifying all potential switching routes of maximum length between unique states, taking into account potential difficulties that may arise when implementing a recomposition information security system. The main tool for analyzing and modeling various transition configurations in the system under study is the apparatus of graph theory. Within the framework of the proposed approach, each subsystem includes several independent options or components, and at any given time only one of these options functions. An important aspect is both the interaction between the subsystems and the ability to switch components within one subsystem. For a visual understanding of the proposed approach, an example is given that illustrates the basic principles and mechanisms of the developed system.

Bamboo as a building material has its own characteristics. It works well in stretching and bending. Bamboo has only longitudinal fibers that are prone to splitting, however these fibers are twisted in a knot. This phenomenon reduces the tensile strength. The mechanical properties of bamboo describe its reaction to physical influences. In general, bamboo has a high tensile strength parallel to the fibers. This article describes the mechanical properties of a bamboo rod depending on the loads, as well as modulus of elasticity of various types of bamboo. This article summarizes the experience of building buildings made of bamboo elements.

In this paper, a new intent and entity recognition model for the subject area of air passenger service, labelled as IRERAIR-TWIN, is developed using the ‘no code’ question-answer development platform ‘TWIN’. The advantages of the no-code platform were analysed in terms of the ease of developing an application question-answer system and reducing the amount of work involved in developing an application model for a narrow subject area. The results show that the ‘TWIN’ system provides an intuitive web-based user interface and a simpler approach to develop the semantic module of a question-answer system capable of solving application problems for a narrow subject area that are not overly complex. However, this approach has limitations for deep semantic analysis tasks, especially in complex contextual inference and processing of large text fragments. The paper concludes by emphasising that future research will focus on using ChatGPT-based ‘low code’ platforms and large language models to further improve the intelligence of the IRERAIR-TWIN model. This extension aims to broaden the scope of the scenarios.
