The current state of the use of methods of stopping wagons on railway transport in cases of their spontaneous departure is investigated. As a result, it was found that cases of spontaneous departure of rolling stock on railways in the region of the Republic of Uzbekistan account for 4.2% of the total share of traffic safety violations and account for 19.9% of the damage caused. This article highlights that in order to prevent the above situations, after installing brake shoes through automatic braking, a device on a spontaneously departing rolling stock, taking into account the number of wagons and their state of loading, based on the development of a mathematical model for determining the stopping distance, a system operating without a human factor was created and introduced into production.

The implementation of Russia’s energy strategy provides for the creation of an intelligent control system for active-adaptive electrical networks of the electric power complex, which contains a system for remote diagnostic monitoring of energy equipment, including metal load-bearing structures of electrical energy generation, transmission and consumption facilities. Promising in this regard is the use of a high-performance electromagnetic-acoustic method, which allows non-contact detection of metal defects and monitoring of their stress-strain state. But existing electromagnetic-acoustic diagnostic tools do not have sufficient sensitivity and information content to solve this problem. The article presents the results of experimental studies aimed at identifying and processing informative parameters of electromagnetic-acoustic transformation for the implementation of remote diagnostic monitoring of the stress-strain state and metal damage of power equipment. Based on the research results, it was proposed to use a frequency model formed as a result of spectral analysis of the electromagnetic-acoustic transducer signal as an integral parameter characterizing the state of the metal.

In the oil and gas industry, to assess the technical condition of equipment, diagnostic methods and tools are used aimed at identifying defects that are unacceptable, according to regulatory documents. In places where mechanical stress is concentrated, microdefects in the metal structure arise, which, under the influence of static and dynamic loads, develop into macrodefects that cause equipment destruction. To identify areas of concentration of mechanical stress and localize metal microdamages, it is proposed to use a non-contact, high-performance electromagnetic-acoustic diagnostic method. But existing electromagnetic-acoustic diagnostic tools lack sensitivity and information content. The article provides an analysis of the influence of the stress-strain state of the metal on the parameters of electromagnetic-acoustic transformation in order to identify additional informative parameters and methods for their processing to solve the problem of identifying the stress-strain state and damage to the metal structure of oil and gas equipment.

Research aimed at the design and development of artificial intelligence systems is currently in great demand. These systems have gained particular popularity when integrated into complex multi-level technical complexes, which include energy industry facilities. The introduction of modern information processes for the rapid processing of technical information makes it possible to develop and implement expert systems for developing generative management decisions using an artificial intelligence system. Such modern approaches in the field of digitalization and information processing, such as the creation of digital twins of physical objects, allow for research and qualitative assessment of management decisions when implementing expert systems.

This article presents the measures and necessary recommendations to reduce the load on the stations, making efficient use of the processing capacity of the stations in the conditions of imbalanced wagon-flows. Also, analyzed the factors that influence the loading of railway stations according to their place of geographical location. Proposals have been made to reduce the level of load arising at the technical stations of the railway using the “Ishikawa” diagram.

The development of logistics terminals and their placement on the railway network, which involves their integration into transport and logistics clusters, will significantly reduce logistics costs, thanks to the optimal technology for the movement of goods, and also contributes to active import substitution and the level of growth in the competitiveness of goods and services. Clustering, which is being given great attention by the Government of the country today, will allow solving some issues of territorial balance of production concentration, increasing the share of high-tech industries, avoiding dependence on trade in resources, increasing the added value of goods, increasing economic growth rates. Modern Uzbekistan has huge transport potential and unique opportunities to meet the needs of the country in the movement of both goods and passengers in all directions by all possible modes of transport through the use of available transit resources. The article analyzes the sectoral structure of the industry of Uzbekistan, shows the existing clusters of the agricultural sector of the republic. The methods of assessing the level of cluster development in the context of the regions of Uzbekistan are described. Paired correlation analysis was used to determine the presence and type of relationship between the studied factors. As a result, the regions of Uzbekistan in terms of the placement of freight infrastructure on railways in order to create potential transport and logistic clusters were grouped depending on the indicators of socio-economic and infrastructural development.

Assessing the quality of automated systems is a very difficult task. This article uses a factor graph and a message passing algorithm to evaluate the quality of the output of the automated local work management system (ALWMS). The proposed evaluation method makes it possible to take into account the impact of each element of the system on the output data.

The purpose of the research is to evaluate the quality of data based on the Bayesian network to justify the effectiveness of the Internet of Things technology in monitoring railway rolling stock. To achieve this, performed the following tasks: presented technological schemes for monitoring railway rolling stock; built Bayesian network; created probability tables; determined conditional probabilities of control events. The existing and proposed railway rolling stock monitoring systems in the Republic of Uzbekistan are investigated. To justify the effectiveness in data quality, made an evaluation based on the Bayesian network. Conditionally selected one section with a train that serves intermediate stations. Two systems monitor this train's railcars: the Automated operational transport management system (AOTMS) and the Automatic control system for rolling stock and containers (ACSRSC). Technological operations transformed into probabilistic relations. The model defines three control events for comparison. The results showed that the quality of data of the existing monitoring system is lower than that of the proposed one. It is due to the dependence on the transfer of information among themselves to the AOTMS. In the ACSRSC system, all information, regardless of previous information, will be received individually. In addition, the level of subjective interventions for the transfer of information is also significantly reduced. The capabilities of ASMSCS are significantly superior in terms of data quality. Subsequent applications of the Internet of Things technology will help improve the quality of management decision-making in the organization of train traffic.

The specificity of the formation of facade and spatial solutions of large spectacular buildings in Kazan is considered in the context of national and regional traditions. Ornamental and decorative systems, adapted to the architectural and artistic styles that existed in this period were identified. The main approaches to the design of large spectacular buildings in the context of national and regional traditions in the architectural practice of Kazan in the middle and the end of the XX century were identified as follows: - based on the use of the dominant styles in the considered periods (classics with the ideological concept of socialism, modernism, postmodernism), adapted to the architectural traditions of the decorative system of the Middle Volga region; - based on the use of modern finishing materials – ceramics, majolica, natural stone, which has references to the traditions of facing the facades of Bulgar buildings with limestone and glazed tiles. The architects of the middle and the end of the XX century laid the foundations of modern regional-national architecture and the methodology for the formation of a decorative-artistic system that combines the stylistic techniques of classicism, modernism, postmodernism with techniques which had references to the Bulgar-Tatar traditions.

Shunting work on sorting wagons is carried out on steeper profiles and requires the operation of shunting diesel locomotives of a higher power. Many sorting operations use double traction of shunting locomotives in conditions of the highly outdated fleet of shunting diesel locomotives. However, the technology of operating two shunting locomotives requires substantiation of its scope of application. In this article, using the example of station “X”, the technology of disbanding trains from the sorting hump is investigated in two ways: the first is the existing technology (work on disbanding trains is carried out using two shunting locomotives of the TEM-2 series), shunting locomotive of TEM-7 series. It has been determined that in the existing technology, the required processing capacity of the hill approaches its maximum value. When using the TEM-7 diesel locomotive, the maximum processing capacity of the hill increases by 27%. The sphere of efficiency of the TEM-7 series locomotive instead of two TEM-2 was substantiated by the method of technical and economic calculations.

The article discusses the topical issue of the establishment of museum and center for contemporary art. The objective of the research is to analyze the historical background of contemporary art museums; to review the world design practice of them according to urban planning, functional, architectural and expositional criteria; to reveal functional features’ trends and to identify the design principles of an advanced center for contemporary art. We collected more than 45 leading examples to compile a matrix using classification and analysis methods. As a result, we reached the museums’ functional features: administrative, exhibition, educational, recreational are fixed functions; storage and research functions are optional; cultural and entertainment are particularly additional functions. At first, art museums and centers are focused on adaption to visitors and intersection with them, secondly, on the exhibit. To sum up, we define the design principles of the ideal architectural model on the basis of urban planning, architectural, sociocultural and technological radicals. In conclusion, it is revealed that contemporary art centers have absorbed most of the historical functions of the museum and today are one of the developed types of the multifunctional architecture.

The article is devoted to calculations of load on rollers of a curvilinear continuous casting machine during bending of the ingot in the levelling section. The calculation takes into account the elastic and plastic characteristics of metal and the flexibility of the roller apparatus. Determination of load on rollers together with meeting other requirements such as reducing the cooling water consumption, minimizing the energy consumption enables optimizing the technology of slab cooling in the secondary cooling zone (SCZ) and obtaining metal of the required quality.

To assess the technical condition and resource for the safe operation of electric and electrical equipment, it is proposed to use the electromagnetic-acoustic effect and the dynamic identification method based on the analysis of the coordinates of the roots of the characteristic equation (polynomial of the denominator of the transfer function of the system “control object electromagnetic-acoustic transducer”) on the complex plane . The transfer function of the studied system “control object electromagneticacoustic transducer” is an integral quantitative parameter characterizing the state of the equipment metal.
