In recent years, heavy haul traffic on AC railways of Russia has caused an increase in electric currents flowing through the elements of the traction power supply system and track circuits, which significantly exceed the design values. Increased electrical loads complicate the operation of traction substations elements, contact networks, relay protection and automation devices, signaling, centralization and blocking system. A significant problem with increasing loads is a rail potential magnification, which violates electrical safety and can even lead to failures and interruptions in railway traffic. The paper investigates rail potential formation along the entire length of the intersubstation zone between traction substations by means of simulation model developing throw MathLAB Simulink software. Based on the findings, further research opportunities for a quantitative assessment of changes and early identification of rail potentials critical values at AC railways. The novelty in this paper lies in the identified and constructed graphics for rail potentials dependence on electrical resistances of different elements and circuit parameters.

In the era of the Fourth Industrial Revolution (Industry 4.0), the issues of timely delivery of raw materials and goods are becoming the main factor in the efficiency of formed transport and logistics chains. The acceleration of the process of cargo transportation in international traffic has an impact on the economic and political interaction of the participating countries. Today, transit transportation of goods and containers should be carried out according to the principles of "seamless" logistics. Such transportation is possible only with the development and implementation of digital technologies and the creation of a single information platform with the connection of all participants in the transport market. The state of the terminal and transport infrastructure of border checkpoints is a limiting element in the movement and processing of foreign trade cargo flows. The purpose of this article is to study the problems of functioning of border checkpoints on the territory of the Far Eastern District of Russia and to consider the criteria for the formation of terminal and logistics infrastructure for the effective passage of projected cargo volumes. The paper presents and describes two groups of criteria – basic and additional. At the end of the article, the existing technological problems in the passage of goods across the state border are considered and tools for improving the efficiency of the organization and promotion of international goods are proposed.

Currently, none of the modes of transport can independently satisfy all customer requests. For example, without the use of road transport, it will not be possible to deliver cargo "from door to door". The increase in the volume of multimodal transport allows to reduce the imbalance between different modes of transport and optimize the transport system. Transportation from the Pacific region is particularly relevant at the moment, as this region is a reliable partner of Russia during the introduction of new sanctions by the European Union. And the active development of the Pacific region In this paper, the transportation of auto parts in containers will be considered, which is also an urgent topic, since the container transportation market shows positive dynamics every year. The purpose of this work was to develop an optimal transportation route from India. [ABSTRACT FROM AUTHOR]

Problems of development of transport and road complex in the era of transformation of socio-economic systems, in particular caused by consequences of pandemic COVID-19, were analyzed. The justification for the need to develop a new strategy for the development of the transport and road complex for the exit of the economic system of the Russian Federation from the crisis is given. The logic of constructing the author's concept is presented, in which the transport and road complex is considered not simply as a factor of economic development, but as an attractor of the development of the socio-economic system of the state. The paper presents an analysis of the picture of state bifurcations and methods of reproducing the transport network. The synergy of the process of influence of transport and road complex on socio-economic system is described. An algorithm for choosing spatial solutions for the development of the transport and road complex has been developed to expand communication opportunities and eliminate the socio-economic asymmetry of the development of individual territories. Conclusions were drawn on the possibility of using the proposed concept of the development of the transport and road complex in the socio-economic policy of the Russian Federation to overcome the crisis caused by the consequences of the COVID-19 pandemic [ABSTRACT FROM AUTHOR]

Taking advantage of the potential of daylighting in the building helps to save energy used for artificial lighting. In Russia and other countries, where most of the energy is consumed for heating in winter, the increased window area leads to a reduction in the energy costs of artificial lighting but increases the heat loss through the windows blocks. Some studies contain criteria for assessing the feasibility of increasing the area of window, however, the influence of artificial light sources have not included. In this paper, the thermal balance of the room is considered, including the influence of artificial light sources, heat gain from solar radiation and transmission heat loss through window blocks. By calculating the difference in the thermal balance of the room after and before the increase in the window area, an expression of the criterion for evaluating the benefits of increasing the window area by energy indicators was obtained. Based on the cost of heat and electricity, the expression of the criterion for assessing the benefits of economic indicators was proposed. According to the presented criteria, the calculation for different function spaces: residential, office and school classes designed for Moscow was carried out. It is shown that, according to energy indicators, an increase in the window area is unprofitable or low profitable for residential and office premises, but beneficial for the school class. In conclusion, the paper shows the possibility of evaluating the energy efficiency of increasing the area of the window using the developed criteria. [ABSTRACT FROM AUTHOR]

In recent years, the world has had different challenges and needs to analyze and track trends in regional economies. This paper examines economic indicators leading to spatial differentiation within macro-regions for the case of both Bulgaria and Russia as countries that have similar conditions on some key indicators of regional development. The analysis period is long - 20 years in order to be able to derive more specific trends in the behavior of production activity. Data on regional gross domestic product, population, foreign direct investment and employment were used as a basis, treating the sectoral and spatial variation within local emerging markets. Hirschman-Herfindahl index is calculated to highlight leading economic activities in different regions for an explanation of ongoing trends nature and an assessment of diversification degree of the spatial distribution of economic activities. We find using the multivariate OLS model that diversification in construction has a stronger influence on regional growth than diversification of the total amount of all investments in all sectors of resourse region. We concluded that foreign direct investment in the regional economies of Bulgaria and the Siberian macro-region would contribute to infrastructural development, which we will investigate later in our next joint works. The guidelines in the differences that are derived are of particular importance in the planning of regional policies and preparation of strategic documents and predetermine the need to analyze regional economies periodically and systematically.

The article was written as part of the general work on the development of a methodology for conducting scientific and technical support during the construction of unique high-rise buildings, related to organizational and technical measures in the implementation of scientific and technical support for the construction of high-rise buildings. This article describes the process of determining the effectiveness of scientific and technical support in the construction of unique high-rise buildings. Due to the fact that the methodology for conducting scientific and technical support for construction is not fixed in the regulatory documents of the Russian Federation, the process of conducting scientific and technical support at construction sites is often formal and does not affect the reduction of construction time, cost reduction, risk reduction, etc. indicators. In order to streamline the process of conducting scientific and technical support for construction, this work is developing a methodology for generating a list of organizational and technical measures that have lists of criteria for the possibility of applying these measures for various unique high-rise buildings. Due to the fact that unique high-rise construction objects are considered, individual organizational and technical measures should be applied to each object, taking into account various geological, environmental, and natural conditions at the objects. The paper presents a calculation of the effectiveness of conducting scientific and technical support, this calculation allows you to determine how effective scientific and technical support will be at the facility in the event of certain organizational and technical measures.

Consumer preferences are one of the major factors which influence consumer behavior and the purchasing decisions. Factor analysis can be applied in order to identify the most significant consumer preferences and to form market segments. The paper presents a methodology of using statistical factor analysis in researching and identifying the key behavioral factors influencing consumers' choice of bakery products. Thus, the study analyzes the possibilities of factor analysis application in the consumer behavior research. The authors propose using the semantic differential method to assess the priorities of consumers in their choice of bakery products. The object of the study is the bakery products market of the Ural region of the Russian Federation. The sample of consumers in the scope of the study consisted of 405 respondents. Statistical Package for the Social Science (SPSS) software was used to analyze the obtained primary data. Factor analysis allowed the authors to identify the key factors influencing the choice of consumers: brand awareness, information on the packaging, naturalness of the product, freshness, presence of taste modifiers, and price. The adequacy of the sample was verified using the Kaiser-Meyer-Olkin (KMO) test and the Bartlett's test of sphericity. The multicollinearity between variables was assessed with the correlation matrix. In order to extract the factors and determine the number of the factors, the authors carried out the principal components analysis (PCA). The results prove that factor analysis allows extracting important factors from consumer survey data and identify consumer segments with specific peculiarities of priorities. A set of marketing communications has been developed for each segment based on the characteristics of the extracted factors. [ABSTRACT FROM AUTHOR]

This paper identifies problems in the country's energy sector associated with low efficiency. Thus, a comparative analysis of statistical data showed that in 2020 there was an increase in the share of unprofitable energy enterprises in Russia from 46.3 to 48.3%, the growth of losses increased to 448,505 billion rubles, exceeding the values of 2019 -141,510 billion rubles, therefore, more than 3 times. It is shown that there is an increase in the degree of depreciation of fixed assets of energy enterprises from 45.7 to 47.6%, which is accompanied by an increase in the costs of maintaining the operability of equipment. In addition, the costs of correcting internal defects are increasing due to the poor-quality organization of monitoring the equipment condition, which also reduces the efficiency of energy enterprises. Different approaches to solving the problem have been summarized: the use of information innovations in the energy sector, the introduction of technological and transactional innovations, as well as innovations in the management of an energy company, for example, the transition to project management or a risk-based management model in the electric power industry. We offer project management to reduce non-manufacturing costs in an energy company on a concrete example of reducing the costs of internal defects correction and implementing an improvement algorithm.

This paper investigates the current state of Indian Railways and dwells upon the present and potential challenges. Railways act as one of the major and busiest networks globally; it is a quintessential model of commercial transport for both goods and passengers. Recognized as the largest employer globally, it is hardly surprising that Indian Railways directly employs 6% of the total employment within the organized sector plus a 2.5% employment that gets generated through other entities dependent on it. The Railways boasts of being the fourth-largest rail network world-wide. Thus it is credited as the most accessible, prevalent, and affordable means of both passenger and goods transport. Having said this, it does face tough challenges in terms of catering to the ever-rising population and keeping a check on operational costs, which puts several constraints ahead of it. A committee of experts has been constituted to enforce reforms and improvements in services from time to time. This study tries to reflect upon the reforms proposed by experts with a special focus on Foreign Direct Investment requirements and creating a sustainable Public-Private Partnership (PPP) model. The study endeavors to benchmark the Indian Railways with the Russian Railways' recent experience implementing the FDI and PPP models. It suggests a way forward to enforce better private participation and dwell upon policy measures to reform the Indian Railways. The study is qualitative and highlights the constraints and challenges that they pose in people's service. To analyze the scenario further, we have tried to draw a parallel with relatable economies like Russia and benchmarked with the Russian Railway's reforms, which could help compare similar reforms in India.

As of today, the Russian Federation puts a special emphasis on the country's digital transformation in general and shows a particular interest towards big data, which is confirmed by a number of documents analyzed and the situation in the subject area. The research paper presented to your attention analyzes big data. One of their application areas is a public sector, in particular, the operation of federal regional bodies of the executive authority. The main value of big data from the governmental point of view consists in the possibility of work with heterogeneous information to improve the efficiency of management decision taking over a wide range of issues. The key research purpose is extrapolating the expertise in big data analysis used in the work of the Ministry of Economic Development of the Primorsky Territory. To do this, the authors suggest addressing to the theoretical assumptions of big data, learning the key chain of work on them and focusing on the national and foreign experience of data use in certain knowledge fields. The practical part of the research includes the description of the operation experience of the Ministry of Economic Development of the Prymorsky Territory directly relating to the region digital development and providing a certain list of works with heterogeneous data. As an example, the authors pay attention to the approved approach to the analysis of a large set of open data, characterizing the SME work and development in the Primorsky Territory, placed at the website of the Federal Tax Service of the Russian Federation. The conclusion highlights the point that the suggested approach on the data processing can be adapted to similar needs in other federal regional authorities. [ABSTRACT FROM AUTHOR]

One of the reasons for the unsatisfactory results of using multidimensional analysis to determine composite quality indices of systems may be the specifics of the data used. Traditionally used as an initial transformation, data scaling does not eliminate the existing data properties. Logarithmic transformation is usually mentioned as possible, but recommendations for its use in the construction of composite indicators are not given. The paper proposes a criterion for the application of logarithmic transformation of variables. Logarithmic transformation is necessary exclusively for anomalous variables. An anomality criteria based on the signal-to-noise ratio of data in a proposed standard form is used. Visually abnormal variables can also be identified using heat maps. The proposed analytical method for detecting anomalous variables coincides with the results of heat map data analysis. The evaluation of the effectiveness of using logarithmic transformation in assessing the quality of poorly formalized systems is examined. Composite indexes of the quality of life for regions of the Russian Federation are calculated. The use of logarithmic correction for anomalous variables solves the problem with the negativity of the weighting coefficients as well as providing a more correct socio-economic interpretation.

The identification and analysis of low-frequency oscillations (LFO) in the parameters of the electrical regime are significant for the efficient operation of power systems. The decision-making loop in most dispatching centers of large system operators includes LFO monitoring. It belongs to one of the most relevant areas of synchrophasor measurement data processing. There are several methods have for determining the source of forced oscillations. However, due to the scale and internal heterogeneity of the power systems, no one provides a final solution to the problem in practice. The paper proposes a combination of methods based on the analysis of the oscillation energy and the amplitude-frequency characteristics of the measuring signals. The paper considers the examples of the LFO analysis in actual cases in the power system of Russia. [ABSTRACT FROM AUTHOR]

The transition to low-carbon development, to reduce the negative impact on the environment, mainly affects the energy sector. Natural gas occupies a stable position of the demand of the Unified Energy System of Russia for 2021-2026 in fossil fuel. When natural gas is burned, thermal nitrogen oxides (hereinafter referred to as NOx) are predominantly formed in power-generating boiler of thermal power plants. This article presents the modeling and study of the natural gas combustion process with the organization of flue gas recirculation to the active burning zone on the example of a power-generating boiler of the TGMT-464 type, using the ANSYS Fluent software package. The paper presents a model and graphs of the temperature and NOx content distribution in the active burning zone with a change in the proportion of flue gas recirculation from 0 to 22%. The decrease in the emission of harmful substances is explained by the decrease in the peak flame temperature in the active burning zone, which is the main indicator of the formation of NOx. The decrease in temperature in the active burning zone is explained by an increase in the volume of gases in the combustion zone. The article is intended for postgraduate, candidate for a doctor's degree interested in the development of methods for suppressing the formation of NOx in the combustion products power-generating boiler at TPPs.

An important task of improving the structural safety of buildings and structures is to improve the methodology for examining their technical condition. One of the significant stages of the building survey is a preliminary or visual survey, during which visible defects and damage are identified that affect the bearing capacity and performance of structures. Further, depending on the degree of damage to structures, the need for a detailed survey of the building with openings of building structures, testing of structural materials and verification calculations is determined. On large objects with a significant number of defects, a visual inspection with fixation of all defects and damages requires a highly qualified expert and a lot of labor. With frequent recurrence of defects, there is a possibility of skipping them and obtaining a biased examination result. A significant increase in the efficiency of detecting defects and damage at the stage of visual inspection can be facilitated by the use of neural network technologies using machine learning methods. Works in Russia and abroad in all fields of science and technology are currently devoted to the study of the operation of neural networks, which indicates the high promise of these technologies. In this paper, we studied a convolutional neural network model created in the Google Cloud Vision API, applied to detect cracks in reinforced concrete building structures. To train the neural network, images of cracks in a real survey object with a monolithic reinforced concrete frame were used. Based on the results of the work, the high efficiency of the constructed model is shown and the possibility of its application in the diagnosis of other types of defects encountered during the inspection of reinforced concrete structures of buildings is indicated.

The data on the apartment buildings technical condition are a huge digital array for making important management decisions both within the boundaries of individual territories of municipal formation, and for planning budget expenditures within the municipality, the subject of the federation and the country as a whole. In this paper the aspects of forming data on apartment buildings in various information systems are considered. Also, the basics of ensuring the reliability of the presented data are studied. The paper notes that for many years, during the transition from a planned economy to a market economy, the requirements of technical regulations and regulatory documents on the maintenance and operation of apartment buildings are not fully observed by operating organizations. The deadlines for replacing the systems and equipment that have worked out are not met. It is noted that the federal legislators and the Government of the Russian Federation have not defined a general procedure for monitoring the technical condition of apartment buildings and have not formed a common approach to assessing their technical condition, the owners' obligation to finance these works has not been defined, their frequency has not been determined. It is shown that the data obtained during the condition monitoring of apartment buildings combined in federal and regional information systems would be an objective marker in the formation of state and municipal programs in the field of reducing the unfit for living housing fund monitoring financing mechanism.

The paper substantiates the systemic limitation of the application of the concept of a smart city in terms of duration of the planning horizon. It is shown that use of this method shall be based on the prerequisites for transforming the urban system itself in order to correspond to the current economic situation. In the analytical part of the paper, the assumption is substantiated that the method that makes it possible to assess and predict changes in the stage of the life cycle of the industrial system of a city are multidimensional classification algorithms that allow to separate objects in accordance with similar characteristics. The feature space of the problem of multidimensional classification will be an array of assessments of factors characterizing the state of the regional industrial system, such as: presence of markets for products to neighboring regions/countries, the availability of infrastructure for implementation of expanded production, and availability of raw materials and labor resources, the intensity of competition; availability of raw materials and local labor resources. As a result of approbation, research results were obtained with a sufficient level of statistical significance based on the estimates of these factors in the 50 largest cities of Russia. In conclusion, it was concluded that the regional industrial subsystems of the largest cities in Russia are at different stages of the life cycle, with the majority at the growth stage, which suggests that in these regions it is necessary to set the goal of long-term preservation of ecological landscapes, the load on which will continue grow in the coming decades. At the same time, in cities with industrial subsystems at the stage of maturity, it is necessary to plan for transition to a new type of arrangement of the regional economy, assuming that the next generation of residents will be mainly employed in the service sector.

The paper shows that the features of development of urban planning policy in Russia, in a historical context, are associated with the fact that large-scale urban planning until recently was not carried out in current conditions, while urban planning realities were based on the Soviet legacy created in other economic conditions, with the assumption of other economic, social and spiritual needs of the city people, both existing and potential. With the change in the economic formation, strategic urban planning, until recently, was not carried out on the required scale; the basic goal on the scale of urban development was to ensure the survival of the population, which also had a negative impact on the state of the space of post-Soviet Russian cities. It is concluded that at present it is necessary to rethink the principles of development of Russian cities, which differ significantly from the urban planning practice of other developed and developing countries. The results of the study indicate that it is necessary to rethink the functionality of the urban environment, its consistent and systematic planning. In conclusion, the paper shows that in order to solve the set tasks, it is necessary to rethink the heritage of several economic and cultural structures of society, considering the current socio-economic and cultural situation. Wherein, the data for the period since 2000 show that at present it is necessary to search for interaction between the various dominants of the city. In modern conditions, decisions in the field of urban planning policy adopted in previous historical periods do not correspond to the current situation; to a greater extent, it is determined by economic reasons or local social priorities.

The article brings into sharp focus the importance of triticale in expanding the raw material base of the bakery industry. More-over, the world leaders in the production of triticale are named, as well as the leaders in the gross collections of triticale in the Russian Federation. The paper generalizes the practical experience of Russian bakers in the production of various types of bakery products with triticale flour. The authors mention the main varieties produced in different Russian regions. Also, they mark innovations of domestic baking industry. The article concludes with a review of promising directions for the triticale flour use. [ABSTRACT FROM AUTHOR]

This paper considers a relatively new issue: the role analysis of Russian cross-border regions in food provision of the country and ensuring food security of the regions themselves. The methodological foundation of the analysis was the studies conducted by Russian scientists, legal documents of the government, distribution statistics of public investments in the cross-border regions. The authors amply demonstrate the inequality in distribution of federal funds to the fixed capital of the cross-border regions, highlight the leading regions and outsider regions. The article assesses the economic development level of groups of cross-border regions, isolated by geographical feature. It is quite convincingly remarked that the Russian Federation has not formed an effective policy regarding the border territories in general, and ensuring their food security, in particular. The cross-border regions occupy a significant part in federal investments. Nevertheless, priority regions that are in acute need of state support to ensure their accelerated development have not been determined. In depressed regions, the average per capita consumption of staple foods that meets the guidelines of the Ministry of Health of the Russian Federation from 2016 has not yet been provided. The authors have traced the underconsumption of such essential human health products as milk, dairy products and vegetables to low incomes of the population. The abandoned status of some territories is the cause of their plight. Today, the issues of these territories are under the jurisdiction of the Ministry of Regional Development, which mainly solves the general problems of the regions. They do not consider the particularities of the cross-border territories and the significance of their development for ensuring food security in Russia. The paper concludes with the specific proposals for solving the topical issues of ensuring food security of the cross-border regions. [ABSTRACT FROM AUTHOR]

For the moment the energy safety of the Kaliningrad region (KR) is largely dependent on the mutual electrical energy exchange through existing connections to Lithuania and further to Belarus and Russia. Taking into account the upcoming KR energy system disconnection from Lithuania, followed by isolated operation (starting from 2025) and wind energy potential of KR, the question of electrical production by the wind as an option for KR sustainable development should be considered. The paper aims to compare three different connection possibilities for onshore power plans (WPP) of different capacity (30 and 90 MW) based on preliminary system power flow calculations using an especially developed energy system model, which are: 1. connection of WPPs to the existing substations of the grid; 2. connection of WPPs to "Wind Grid" ("WG") – new lines and substations in energy system especially constructed for wind energy production; 3. simultaneous connection of WPPs to existing substations and to "WG". The conclusion of the paper is 1st the option is the cheapest, but not viable because WPPs create additional problems with voltage levels and lines overload. Some measures to overcome observed problems are proposed. The electrical system parameters, such as voltage levels, power flows, and power losses are very close for the 3rd and 2nd options. The 3rd option is more expensive, because of additional switching equipment, but most flexible and easy to handle for the system operator. [ABSTRACT FROM AUTHOR]

In this paper, the formation and development of Vietnam's metallurgical industry and the recent crisis are presented. The cause of the underdevelopment is backward production technology and slow transformation to meet the increasing requirements of the market. The paper also clarifies the development of automatic control system (ACS) and the production execution system (MES) in metal production in the world and Russia can be applied in Vietnam; The current problem of Vietnam's metallurgical industry is that the production technology is still outdated, the output is low, the product quality is not high and consumes a lot of energy. The solution to solve the above problems is to improve technology based on applying automatic control systems and MES systems to the operation and production of enterprises. [ABSTRACT FROM AUTHOR]

Car-sharing is a phenomenon, which is becoming increasingly widespread, first of all, in large cities. Since its inception in Russia, this phenomenon has become the object of scientific research by scientists from various branches of science, as well as the object of attention of journalists and practitioners. The benefits of car-sharing are obvious, its active use in megalopolises and large cities allows eliminating traffic jams, mitigating the problem of the lack of parking spaces, and reducing the amount of CO2 emissions into the atmosphere. At the same time, there are many problematic aspects in the concept of car-sharing, primarily in the legal sphere, which are exacerbated as it spreads and increases in popularity. First of all, it is the problem of the safety of using carsharing for the driver and passengers. Moreover, it is necessary to ensure the adherence to the rights of car-sharing users, on the one hand, and the car-sharing company, on the other hand, which is possible only by detailed and effective legal regulation. The main legal problems of using car-sharing in Russia, including the issues of the security of this service are analysed in this paper. Based on the study conducted, the authors have developed recommendations for improving the legal regulation of the use of car-sharing. [ABSTRACT FROM AUTHOR]

The paper is devoted to the review of problematic and controversial issues of the development of railway transport in Russia at the beginning of the 20th century. When finding out the reasons for the disruption of railway transportation during World War I from 1914, which became even more aggravated during the 1917 revolution in Russia, some railway engineers, including revolutionary-minded, considered the operation of technical inspection and state control institutions in the industry adverse for the development of railways. From the point of view of some railway engineers, the normal functioning and development of the railways were possible only in the presence of specific conditions, i.e. its organization in all major details strictly corresponding to the nature of the business; complete stickiness to the plan of its course and full coordination of the operation of all parts of its complex mechanism without exception; properly trained and specially selected personnel set in conditions that ensure the best possible use of its business qualities.

The Russian market of transport and logistics infrastructure developed rather slowly in 2019. By the way, there was nowhere to expect breakthrough indicators – the growth of the world economy is slowing down, and therefore the decline trends are inherent in many industries around the world. Delivery volumes gradually gained momentum, but in early 2020 there was a crisis – the COVID-19 pandemic, which swept the whole world and changed the lives of not only millions of people, but also the situation in the international and regional markets. The closure of borders between countries and the introduction of a self-isolation regime has led to a significant reduction in the volume of production capacities. The COVID-19 pandemic, having disrupted the established ties between producers and consumers around the world, has made serious adjustments to the business processes of transport and logistics organizations. The paper analyzes the features of the formation and functioning of logistics chains for Russia and the world. Global trends in the development of transport and logistics infrastructure in the modern conditions of transformation of economic relations were identified. [ABSTRACT FROM AUTHOR]

The paper deals with the issues of response to abnormal and emergency situations, including threats of and acts of unlawful interference on vehicles and transport infrastructure facilities of the railways of the Russian Federation. The response process is considered in terms of the regulations of interaction between the units in charge of the response and transfer of information about an accident. Based on the results of the analysis of regulatory documents, the data on the response processes in the event of threats, acts of unlawful interference and other abnormal and emergency situations were structured. An algorithmic model of the response process of the structural units of the railway, forces and units responsible for transport safety on the transport infrastructure facilities and vehicles and other safety authorities under threats, acts of unlawful interference and other abnormal and emergency situations have been developed.

Recent studies have shown that scientists can benefit from participation in scientific networks as they can receive more and better information in a timely manner and have communication between employees. This paper shows an approach based on the use of methods of analysis of social graphs and thematic modeling to study the community of scientists working on the topic of hematology oncology in Russia. The proposed approach makes it possible to effectively identify research teams, as well as understand what issues they are working on at the moment. The use of this approach allows bringing the strategic management of scientific research within the framework of a scientific or educational organization to a new level, since it allows making data-based decisions in terms of scientific collaboration and assessing the long-term consequences of such decisions. In the work under consideration, the data of 2140 scientific articles from the Scopus / WoS databases on the topic of hematology oncology for 2016-2020 were used. [ABSTRACT FROM AUTHOR]

The paper describes more important stages of introducing nonlinear soil model into design practice in Russia. Results of laboratory and in-situ verification studies are analyzed. Some examples of objects which geotechnical parts were designed using a physically and geometrically nonlinear soil model are given and discussed. Since the soil is a natural media, the values of its mechanical characteristics (parameters) should be determined from in-situ static tests, for example, using pressuremeter devices, that allows to ensure the necessary accuracy in about 25% of the design geotechnical output data.

This paper discusses the concepts and organizational foundations of ensuring the information security of an organization in the context of the digitalization of the economy. The relevance of the study of the problem posed has been proved, since in modern realities there is a widespread introduction of information and software technologies. It is shown that the digital economy is one of the main directions of the strategic development of Russia - the digital transformation of various spheres of human life requires the most careful measures to ensure cybersecurity and protect the confidentiality of information resources. The role of the latest technologies for processing "big data", the implementation of high-tech solutions in order to ensure reliable, timely, long-term and safe storage of databases is clarified. It is shown that the modern information environment is unprecedented in terms of the presence of threats and risks that can manifest themselves in various forms; in this regard, it was proved that it is extremely important to timely and constantly identify and analyze emerging threats and risks, as well as ongoing changes in the information infrastructure. It was also proved that only with this in mind, it is possible to design and build an effective information security system based on the formation of an extensive information infrastructure that allows to provide timely and secure access to information that organizations need.

The author of the paper shows that an important factor in the location of the production of building materials is the availability of sufficient raw materials in the region. The northern regions of the Russian Federation in general and the Republic of Sakha (Yakutia) in particular have rich reserves of raw materials for the production of building materials. In addition, the author draws attention to the fact that despite the presence in Yakutia of its own mineral resource base, at present there are factors that contribute to the delay in the development of this industry: the use of technologies that are outdated and energy-intensive, the uneven distribution of production capacities for the production of building materials on the territory of Yakutia. This contributes to an increase in the cost of construction, arising from high tariffs for transport services. The need of Yakutia in large volumes of building materials is due to the expansion of the housing stock, industry and road network. In this connection, the production of building materials on its own in the harsh northern conditions will allow the republic to reduce the cost of their importation from other subjects of the Russian Federation.
