A project is a single system, an interconnected network of elements: participants, resources, processes, and goals. This relationship is critically important for successful implementation by the technical customer service. Processes that are clearly defined and managed ensure consistency and efficiency. Therefore, project design and management requires a systematic approach that takes into account all relationships and strives to optimize each element to achieve a common goal. A system approach is a method that considers a problem or task in terms of its interrelationships and interactions of all elements of the system. In the context of a technical customer service, this approach can be particularly useful for project management, process optimization, and work efficiency improvement.

The purpose of developing the model and algorithms is to improve the management of public training in the field of public protection and civil defense of the Republic of Tajikistan as an integrated system that combines a set of interconnected elements that form its emergence and are determined by a set of functional properties, hierarchy and multiplicity of descriptions, as a complex organizational system [1]. The research uses methods of analysis and systematization. In particular, John Cotter's model of change is used, which allows structuring the process of managing the training of the population at different levels. Algorithms have been developed that take into account different social groups and their specific needs. This makes public education programs more adaptable and accessible to everyone. The obtained training algorithms can serve as a basis for improving public training management in the field of public protection and civil defense by integrating them into functional and infological models. The mathematical model of assessing the readiness of the population makes it possible to identify weaknesses in the training of the population and develop specific measures to eliminate them. The developed training management model and algorithms contribute to the formation of a structured system focused on the real needs of citizens. This includes their active participation in ensuring security, which, in turn, contributes to the creation of a more secure and secure environment in the country. The results of the study can be the basis for further development of the civil defense system in Tajikistan and improvement of training in the field of public protection and civil defense in emergency situations.

The number of information security incidents and the amount of damage caused by them are increasing every year. The relevance of information security incident response remains high. The primary response action is an information security incident localization. The purpose of this study is to reduce the time taken to localize detected information security incidents by information security incident response teams. The purpose is achieved by issuing and using a mandate for information security incident localization by orchestration tools and/or artificial intelligence systems in an automated mode. Analysis and synthesis of available publicly materials were applied as research methods. The results of the analysis and evaluation of different criteria applicability for granting a mandate to localize an information security incident in an incident response are presented in the article. A mandate is granted to orchestration tools and/or artificial intelligence systems to perform localization of an information security incident in an automatic mode, i.e., without the involvement of information security incident response team forces. In evaluation the applicability of various criteria for granting a mandate, unlike the known ones, the level of difficulty in determining values for the criteria in question by information security incident response team forces alone was assessed. Criteria and their values are defined, which, unlike the known ones, highlight the area for information security incidents localization in automatic mode.

The article is devoted to the analysis of the process of redesigning industrial buildings in Moscow in the context of urban development of the city. Based on data from the Moscow Department of Investment and Industrial Policy (2023), the current state of industrial zones (hereinafter referred to as industrial zones) is being investigated: 25% of the 150 facilities have already been redeveloped, and over 80 enterprises have been moved outside the MKAD since 2010. Successful transformations (ZIL, Hammer and Sickle, Red October) and criteria for choosing new functionality are considered: location, historical value, ecology, transport accessibility. Using cartographic data, promising areas for renovation (AZLK plant, Compressor, Rubber) have been identified and options for their adaptation have been proposed, from creative clusters to residential complexes. The role of redevelopment in the sustainable development of the city, the need to comply with environmental standards and take into account the needs of local communities is emphasized.

The article describes the process of sedimentation in water treatment, as well as the formation of tap sludge. A new method of water supply sludge treatment with coagulant regeneration at high turbidity of initial water is proposed. On the basis of the conducted research it is revealed that the greater the coagulant consumption obtained by the sulfatization method, the better the degree of coagulation. The basic technological scheme of water sludge processing by sulfatization method is developed. It is suggested that the obtained coagulant from water supply sludge can be used for repeated preliminary sedimentation. Taking into account the urgency of the problem of providing the population with clean drinking water, it is recommended to conduct pilot testing of the obtained coagulant from tap sludge by the sulfatization method.

This paper presents the results of a study aimed at developing a method for semantic segmentation of thermal images using a modified neural network algorithm that differs from the original neural network algorithm by a higher speed or processing graphic information. As part of the study, a modification of the DeepLabv3+ semantic segmentation neural network algorithm was carried out by reducing the number of parameters of the neural network model, which made it possible to increase the speed of processing graphic information by 48% – from 27 to 40 frames per second. A training method is also presented that allows to increase the accuracy of the modified neural network algorithm; the accuracy value obtained was 5% lower than the accuracy of the original neural network algorithm.

The effect of nanosized boehmite microadditives on the surface properties of carboxymethyl cellulose polymer suspensions with aluminum microparticles was studied. It was found that with an increase in the boehmite content from 0.10 g to 0.20 g in suspensions, the surface tension of liquid systems increases by 8 mN/m. The contact angle of the liquid composition wetting the fluoroplastic surface also increases: from 62 ° to 85 °. It is shown that on a low-energy fluoroplastic surface, boehmite nanoparticles act as a pore-forming agent, leading to the generation of ordered cells on the surface of films formed from suspensions. The morphology of the initial powders and the formed films with cells was studied using optical and electron microscopy. It was established that ordered cells of similar size with dimensions of ratio 500 to 1,000 microns in size are formed with a boehmite content in the base composition of 0.15 g.
