Authors: Smirnova Elena , Ataev Azat 
Published: October 2020

Abstract
The authors of the article propose a number of measures to optimize the production process of “Garabogazcarbamide” factory in order to increase its environmental safety. The factory and the newly equipped berth in Garabogaz (Bekdash) have a negative impact on the ecological situation of the Caspian Sea, in particular, Garabogazgol Bay. The fragile balance between economic activity and preservation of the ecosystem and its biodiversity is broken. Potential accidents at drilling rigs and oil-gas transport and industrial complex can lead to extreme consequences and desertification of the region. The threat of environmental degradation in the Caspian region and the depletion of its natural resources are especially great due to the overdevelopment of the fuel and energy industry, the lack of legal regulations for environmental protection, the limited use of energy and environmental technologies and a primitive environmental culture; all these factors increase the risk of technological disasters. According to the authors’ opinion, the organization of a system of continuous environmental monitoring over the technological updating of the factory equipment; the use of a closed JW system (including desalting unit); the construction of its own power plant for the needs of the factory; purification systems for atmospheric emissions; improving smart technologies to reduce natural gas consumption can help to improve the environmental situation in Garabogaz.

Published: October 2020

Abstract
The long-term development program of the Russian Railways holding provides for a comprehensive modernization of the railway infrastructure by The least expensive of these measures is the use of contact elements with an extended service life, providing reliable, economical and environmentally friendly transmission of electricity to rolling stock. In accordance with the program developed and successfully tested at OSTU, the methodology for conducting experimental studies of contact pairs of current collector devices for conducting a test cycle requires specialized experimental complexes, as well as significant time and resources. To reduce the volume of experimental studies, a combined method is used - a combination of the required minimum of experimental studies of real objects (or their analogues) and calculation methods based on mathematical modeling of processes occurring in contact pairs of current collector devices. However, the use of existing mathematical models for predicting wear under conditions of very high-speed movement is not accurate enough due to the lack of consideration of the aerodynamic effects and the speed of the rolling stock on current collection processes. This article discusses the improvement of the electrical component of the wear model of the elements of contact pairs of current collector devices under conditions of very high-speed movement. The histograms of the electrical wear of contact elements obtained by calculation using the existing and improved mathematical models are presented.

Abstract
The oil coolers are used in the hydraulic system of transport vehicles. In the shell and tube water oil coolers, oil is can be located on the tube side, water in the shell side. Different enhancement of heat transfer methods is used in oil coolers. The paper presents the results of a numerical study of the effect of asymmetric flow pulsations on the enhancement of heat transfer in a pipe for a highly viscous fluid with a Prandtl number Pr 293. The pipe length was 12 pipe diameters. The Reynolds number Re calculated from the inner diameter of the pipe was 100. The Strouhal number Sh was inside the range from 0.14 to 1.13. The amplitude of the pulsations of the flow had a reciprocating motion. The dimensionless relative amplitude of the pulsations was 1, 3, and 5. An increase in heat transfer was observed over the entire range of pulsation frequencies and amplitudes. The intensity of the pulsating flow significantly increases the heat transfer in the pipe. A comparison of the effectiveness of harmonical and asymmetric pulsations for enhancement of heat transfer was carried out. It is noted that the efficiency of asymmetric pulsations increases with increasing amplitude and frequency of pulsations. The maximum enhancement of heat transfer with asymmetric and harmonic pulsations was 2.03 and 1.93, respectively.

Abstract
The shell and tube heat exchangers are widely used in many engineering applications. Tubular heat exchangers can be found in the transport, power engineering, food industry and etc. Therefore, the study of the characteristics of heat transfer and hydrodynamics in tubular heat exchangers is important. In this paper, numerical analysis of a heat transfer in a staggered tube bundle with steady and asymmetrical pulsating flow studied. The transverse and streamwise spacing-to-diameter ratios of the tube bundle were 1.3. The Reynolds number Re was 1100. Numerical simulation of the flow past the tube bundle with 7 longitudinal rows was carried out by solving the incompressible Navier-Stokes equations and energy conservation equation with two different modeling strategies. The simulation was carried out with the RNG k-ε turbulence model with enhanced wall treatment and laminar solver. The sensitivity of the Nusselt number to the mesh parameters is noted. The effect of the number of rows of the tube on the heat transfer rate for the tube bundle with the pulsating flow also was discussed. For the pulsating flow enhancement of the heat transfer in the tube bundle dependence from the row of the tube and modeling strategy. When RNG k-ε turbulence model was employed the heat transfer rate of the first row is increasing by 16 %, downstream rows by 6-7 %. When laminar solver was employed the heat transfer rate of the central rows are increasing by 53 %.

Authors: Bannikov D A , Sirina N F 
Published: October 2020

Abstract
The passenger rolling stock has a number of specific technical characteristics based on original design and technological solutions. The consequences of the passenger rolling stock failure cause unplanned downtime, resulting in: reduced productivity, traffic safety and quality of service, as well as financial losses. Determination of cost-effective maintenance and repair becomes one of the key tasks in the operation of passenger rolling stock. At present the tools for planning maintenance and repair of passenger rolling stock are static. They do not take into account dynamic information during the life cycle of the rolling stock. The planning tools are mainly a copy of the maintenance and repair organization manual. This article deals with the digital model of maintenance and repair of passenger rolling stock as a transformation of strategy from diagnostic to predictive. The modeling serves as a fundamental starting point in managing the life cycle of passenger rolling stock. The theory of passenger rolling stock life cycle is complemented by the theory of management, creating a model of service maintenance and repair. The digital model covers the life cycle of the passenger rolling stock from initial planning to a multitude of solutions, such as: separation in the mechanism of financing, service operator selection, definition of key performance indicators for the operator, setting fees, maximum profit, providing access to all operators of railway services. At the conceptual level, the fundamental aspects of the digital service model have been developed to forecast future events and make optimal plans, taking into account the multivariate and structural heterogeneity of data in the virtual networks. The modeling approach oriented to the global description of the business process and distributed management of service maintenance and repair is considered.

Published: October 2020

Abstract
The article analyzes the current state of the transport service sector of the Russian Federation and shows that it occupies a dominant place in the structure of GDP, and more than half of the able-bodied population of the Russian Federation are employed in the transport service sector. Based on the analysis of the internal and external environment of the transport service enterprise, the influence of the digital transformation of business processes on the enterprise as a whole is investigated. Methods for identifying and analyzing risks are proposed, these methods are considered on the example of a transport service company. The identification process was carried out using the method of SWOT analysis, which showed that the strength of the enterprise is automation and high technology, and the main risk is the risk of revenue shortfall, which is associated with factors such as failures in the work of information technology, low efficiency of online marketing, failures in reservation system, imperfection of personnel selection and assessment information programs. The study showed that a transport service company is exposed to risks with a high probability and a significant amount of damage; such risks require preventive measures to eliminate them. The proposed methods for identifying and analyzing the risks of digital transformation will be useful to senior management of transport service enterprises.

Published: October 2020

Abstract
The article deals with the development of algorithmic support for the implementation of the process of functioning of transport systems in the region with a dynamic change in the conditions of functioning of regional management of transport systems as a result of untimely decision-making. In managing the functioning of transport systems in the region, systematic and integrated approaches are not fully used in the formation of a set of management decisions aimed at ensuring the safety of transport systems, namely, there are no models that would establish a one-to-one correspondence between the situation (generating potential threats), information and analytical activities (identifying potential threats) and the system for ensuring the safety of transport systems, designed to develop an adequate management decision and its development. The proposed algorithmic software allows us to overcome these disadvantages in the managing the functioning of transport systems in the region.

Authors: Medyakova E M , Kislitskaya N A , Kudinova S G , Gerba V A 
Published: October 2020

Abstract
The global transport infrastructure has evolved in recent years, gradually incorporating digital innovations into traditional processes and services. However, everywhere the process of digitalization was hindered by the priority and low cost of classic forms of transport services, the absence of strict requirements for compliance with the conditions of contactless movement of products and prevention of the spread of infections. According to the authors, the vector for total digitalization was taken after the spread of the SARS-CoV-2 virus. The authors analyzed the implementation of digital tools until 2019, assessing the degree of implementation and coverage of digital innovations in the global transport industry. Having studied the transport system of Russia, as one of the world’s largest systems, in the context of the COVID-19 pandemic, the authors showed how the structure of cargo turnover by the mode of transport has changed and which industries have suffered the most damage. Having calculated the forecast of digitalization growth and the dynamics of the share of digitized processes in the global transport infrastructure, the authors have come to the conclusions about the acceleration of the accumulated potential of digitalization of the transport sector in the context of the COVID-19 pandemic.

Published: October 2020

AbstractProductive land, which primarily includes agricultural land, in any country in the globe, always had special status since they are the basis of the country’s food security. The tasks of identifying, recording and preserving land from misuse, depletion, and degradation are in priority when pursuing a state land policy. Recently, these issues have become particularly important due to the high rates of land depletion and degradation, urbanization, industrial and mining development. The most fertile land in Russia classified as the most valuable agricultural land. After analyzing the situation with the definition, recording, and protection of such land in the Russian Federation, the authors concluded that the country does not have clear, objective criteria and methodological approaches for identifying the most valuable land, as well as mechanisms for their protection. This paper provides the basic principles, methodological approaches and the results of the work on the identification and allocation of the most valuable land in agriculture and transport sector of Siberia. Land of 1-5 classes one way or another should be protected from unreasonable withdrawal from agricultural use, land of 6-8 classes may be provided for the development of transport.
