The article proposes the optimization of the existing device for improving the noise immunity of audio frequency track circuits. Due to the fact that the signal current in the audio frequency track circuit is a tone frequency signal modulated by pulses, by opening the transmission path of the audio frequency track circuit at the input of the track receiver during the intervals between signal current pulses, the track receiver can be protected from interference. To take into account the delay time for the signal to pass from the output of the track generator to the input of the track receiver, a delay line is provided in the device for increasing noise immunity. But the time of passage of the signal current in the path of the audio frequency track circuit may vary depending on its operating parameters. To take into account these fluctuations and to increase the efficiency of eliminating interference in the intervals between useful signal pulses, a method of adaptive control of the delay line is proposed, which allows adapting the delay time parameter depending on the length of the rail line, the carrier frequency of the signal, the insulation resistance and the frequency of the modulating signal. By solving the problem of classifying data containing information about the influence of the operation parameters of the audio frequency track circuit on the signal transit time, the optimal structure of the model based on neural networks was chosen. This model implements the method of adaptive control of the delay line.

Economic security of enterprises consists of various components, such as financial, personnel, production, legal, organizational, technological, marketing and others, each of which has its own tools that include elements of accounting and analytical support. The author summarizes the structure of the components of economic security and identifies certain factors that affect security within each component. CRM-systems are a technology of interaction with customers, which helps to optimize business processes in the company and increase the efficiency of components such as organizational, personnel and marketing security of the enterprise. The use of modern technologies can speed up the processing of information coming from the consumer to the company through the analysis and promotion of marketing companies, synchronization of logistics channels of the company, assessing the effectiveness of staff on certain projects and tasks and more. The article considers domestic CRM-systems and compares their functionality in the implementation of improving the economic security of the enterprise. The strengths and weaknesses of these systems have been identified. In general, the review aspect of the article focuses on the identification and analysis of modern domestic product in the framework of the refusal to mass use of similar products of Russian companies. As a result of determining the impact on the components of economic security of the implementation of CRM systems, it is possible to come to a conclusion about the necessity of their application in business activities in order to improve the efficiency of economic security. The CRM systems considered in their base have warehouse management components, connection to logistics channels and marketplaces, work with telephony and analytics. The established advantages and disadvantages will help to make a choice in favor of this or that system and its implementation at a specific enterprise based on the management tasks of the management.

The world community is currently facing economic, environmental and social problems that are interconnected at the global level, problems that no country will be able to cope on its own. Therefore, it is time for the G20 Member States to adopt a shared vision that will enable the world's population to achieve an economically prosperous, environmentally sustainable, socially inclusive future, resilient to unforeseen shocks. This highlights the importance that the G20 attaches to current global issues affecting people's lives around the world. The G20 was created as a structure that can respond flexibly to global challenges. Unlike other international platforms, it does not have a rigidly defined, narrow scope of authority. It also does not have a secretariat with clearly defined bodies. The number of member states is quite small, which allows for collective governance. This prompted us to examine the evolution of the G20 agenda over the last 10 years in terms of the scope and depth of issues covered, priority sectors, tailor-made mechanisms and packages, and, above all, the impact of development.Based on the analysis of economic distancing by different parameters of countries and regions, the global problem of uneven development of human potential and income due to different state of economic systems, resources and technologies, economic policy management and efficiency of investment in technological and innovative development. The systematization of modern economic and political associations indicates the combined efforts of states and regions to solve common environmental, economic, social, cultural, technical problems despite the different levels of economic development and resources, as well as to pursue different national economic interests. However, only the consolidation of efforts makes it possible to determine the potential for solving common global problems of states. These proposals and vectors of development of the G20 countries will improve the positive impact on the world economic system in order to balance global economic development, address poverty, hunger, environmental crises, technological gaps.

The need to study mediationand its role in resolving conflicts is due to modern reality, since conflicts are often based on cultural and civilizational differences. Therefore, today and in the future, there are issues of social behavior, interethnic and interfaith dialogue in society. Mediation does not accept the paradigm of revolutionary changes and does not accept the forceful solution of problems. A conflict is interpreted as “one of the types of social interaction of individuals, social communities, and social institutions, in which the actions of one side, faced with the opposition of the other, impede the implementation its goals. The psychology of management help people through research in theory, practice, methods and cases, to achieve betterdecision-making, leadership practices and development,problem solvingand improve overallhuman relations. The phrase "cultural conflict", although it is found in cultural publications and in journalism, however, appears in a narrow sense as a general antipode of harmony, tolerance and an ideal to which one should strive. Without claiming to fully realize this goal, we hope that the efforts made within the framework of our research program will be useful in clarifying some necessary details of the future theoretical and cultural picture of the conflict as such and the role of mediation in its resolution. The goal set determined the nature of the following tasks: (i)in the context of the culturalapproach, to analyze the history of the formation of ideas about the conflict as a socio-cultural phenomenon and, in this regard, pay special attention to the evolution of understanding the role of mediation in resolving various social conflicts; (ii)to explain in a cultural context the reasons for the formation of mediation as one of the modern civilizational means of "alternative resolution of disputes (conflicts)"; (iii)to consider the features of the manifestation of conflictogenity in the life of modern society; (iv)reveal the nature and essence of mediation as an effective social institution in culture.Conflicts are studied within the framework of almost all scientific social disciplines. And the essence of the concept they consider will be constantly refined and analyzed in its special meaning. For many centuries, well-known thinkers, philosophers, scientists, reflecting on the nature of the unity of human society, one way or another brought to the fore cultural-philosophical and cultural fundamental problems of the theory of conflict.

The article considers the problems of energy efficiency management of the rolling stock of the transport sector. The operation and operation of vehicles are analyzed and it is determined that road transport is the main consumer of energy resources in the transport sector, which is about 90%. Road transport requires 6.5 times more fuel than rail, and 5 times more fuel than sea or river. It has been studied that the transport sector has a negative impact on environmental friendliness due to high emissions. To successfully solve this problem, it is necessary to use bioenergy, which will increase the energy efficiency and environmental friendliness of the transport sector and is a strategy for the development of the transport sector of the country and the European Union. An analytical review of legislative acts, namely EU directives and national transport strategy for the period up to 2030, which regulate the promotion of energy efficiency in transport. The main groups of tools and the use of information technology are considered, which allow to achieve the set goals in the development of energy efficiency in transport. The impact of alternative fuels resulting from the processing of biological waste or biological raw materials for the country's transport sector, in particular road transport, which will significantly reduce CO2 emissions, has been studied. Biofuels are able to provide clean energy for all modes of transport and are currently the most important type of alternative fuel. Its influence on improving the energy efficiency and environmental friendliness of the transport sector has been studied.

The management of the vessel's course on the course is an important maritime quality that determines the effectiveness of the vessel's management. The environmental conditions in which course management tasks need to be addressed are of a different nature - limited visibility, stormy weather, icing, shallow water, tidal phenomena, narrow conditions, the presence of other vessels, and so on. All these aspects cannot be comprehensively considered by traditional mathematical methods, ensuring the necessary adequacy of the actual process. This paper highlights the existing approaches to the management of ship traffic on the course such as course management, disturbance management, ship traffic management on the basis of long-term forecasting, proportional-integral-differential (PID) law of control (deviation control), intellectual approaches to court management, in particular, synergetic approach, use of neural networks, fuzzy logic and evolutionary (genetic) algorithms-languages.

This paper explores the practice of using ash and slag and fly ash from thermal power plants in road construction as one of the ways to dispose of industrial waste. The purpose of the study is to determine the chemica l composition of TPP ash and slag to study the possibility of using it as a raw material for road construction. To achieve the goal, the following tasks were set: to determine the main physical and chemical properties of ash and ash and slag from thermal power plants, to give an environmental assessment of the use of these wastes in road construction. Chemical analysis of ash and slag from Zmievskaya, Krivorozhskaya, Trypilskaya, Slavyanskaya TPPs was carried out to determine the main components: SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Nа2О and К2О. The content of heavy metals was determined using the method of atomic absorption analysis. The migration ability of heavy metal compounds from the roadway using ash and slag in the construction of roads has been studied using the construction of concentration-logarithmic diagrams. To predict the migration of heavy metal compounds into the environment when they are used in road construction, a separate dependence of the concentration of the most probable ions was plotted (for example, cuprum) [Cu(OH)n 2-n] on the pH of the environment. The lack of migration of cuprum compounds in a neutral and alkaline environment has been proven, which makes their use safe. Similar calculations were made for other metals.

Realization of enterprise goals along with other important components of providing successful activity requires the formation of a favorable moral and psychological climate in a collective, which is considerably promoted by qualitative primary personnel selection. And although an enterprise management takes on vacant positions candidates whose professional and personal qualities best meet the requirements of the possibility to perform the functions, still the emergence of conflict situations in the collective because of misunderstandings on the production or personal nature, unfortunately, is inevitable. Such situations arising in the process of work require from a manager of any level to urgently resolve them, so a skillful manager must be ready in advance to ask himself and his subordinates a number of questions, how to ensure the motivation, willingness and initiative of employees; what to do if an employee has a potential that for certain reasons can not be realized; how to ensure the full use of competence of employees; how to ensure the proper moral and psychological climate in the collective; how to organize work in the collective. Honest and frank answers to the right questions will help members of the collective, first of all, to understand themselves and find the right way out of the situation for the benefit of themselves and the enterprise. This article's model of neurological levels is of purely utilitarian interest as one of the manager's or supervisor's effective instruments for a structural analysis of certain problems in an enterprise, particularly, those resulting from low personnel efficiency. Having mastered and deliberately used the model of neurological levels, manager of any link, understanding the benefits of this approach, can, if necessary, also turn to a professional coach to implement the necessary changes in the organization of personnel work, which will help to get the desired moral and psychological climate in the labor collective and avoid failures in the enterprise due to the «human factor».

This article's model of neurological levels is of purely utilitarian interest as one of the manager's or supervisor's effective instruments for a structural analysis of certain problems in an enterprise, particularly, those resulting from low personnel efficiency. Having mastered and deliberately used the model of neurological levels, manager of any link, understanding the benefits of this approach, can, if necessary, also turn to a professional coach to implement the necessary changes in the organization of personnel work, which will help to get the desired moral and psychological climate in the labor collective and avoid failures in the enterprise due to the «human factor».","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87577689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article considers the current problem of uneven electricity consumption in railway transport and steps to reduce it. The analysis of conditions of operation of traction rolling stock is carried out. Based on the results of the analysis, the characteristics of the modes of operation of traction rolling stock of railway transport and energy processes in the system of electric traction during their implementation are given. The factors that lead to energy losses due to uneven traction power consumption are presented. Indicators for estimating the unevenness of traction electricity consumption in the case of the subway and suburban rail transport are proposed. The use of integrated energy indicators peak factor and shape coefficient is proposed as indicators. The peak factor characterizes the level of excess power of the power supply system, the shape coefficient - losses in the traction power supply system. According to these indicators, the time diagrams of electricity consumption at the feeder of the railway traction substation and the subway electric train were evaluated. The results of the quantitative assessment confirmed the adverse effect of certain factors on the unevenness of traction power consumption. It was found that the modes of operation of the subway electric train provoke more significant energy losses in the elements of the traction power supply system compared to the railway. It is proved that regenerative braking increases the unevenness of energy consumption, increasing the load on the traction network and contributing to the emergence of pulsed currents in the traction power supply system. Concepts for overcoming the problems of uneven traction power consumption and the use of excess energy recovery are based on the use of energy storage as an additional power source for traction drive.

The article deals with the models of dump cars, which form the major part of the mainline railway car fleet of 1520 mm. The technical characteristics of the most common mainline dump cars models are given. The design features of the dump car model 31-638, designed for transportation and mechanized unloading of bulk and lump cargo, are presented. Modern models of dump cars of domestic and foreign production for the main railway transport of 1520 mm track, which were constricted and put into serial production in recent years, are presented. The results of comparative analysis of technical characteristics of dump cars of the last generation to modern models of dump cars showed that one of the main advantages of the latter is reduction of container weight, increase of load capacity and body volume, improving of strength and reliability of separate units and systems. The problem units and systems of the existing models of main-line dump cars are determined based on the results of their operation, which need further strengthening. The focus areas of improving the design of modern models of dump cars for the 1520 mm main railway vehicles are defined. The technical requirements for the next generation dump cars, which are planned to be constructed and put into serial production in the coming years for operation on the mainline railway tracks, are proposed. The technical requirements are formed taking into account the research results of modern mainline dump cars design, review of technical and design documentation for these railway vehicles, as well as analysis of requirements and wishes of customers. The necessity of carrying out relevant research and engineering works on the development of new generation dump cars for the main railway transport is substantiated. The content of the article will contribute to the construction of new models of dump cars for the main railway transport and significant upgrading of existing models, as well as increase the efficiency of their operation.
