Use of pulsed spray airflow for electric arc spraying of different types of wires
Authors: Royanov Vyacheslav , Zakharova Irina
Published: July 2021

The object of research is the control of the process of formation of a spraying air flow and the transfer of particles of liquid metal from electrodes during arc spraying. One of the problem areas of the arc spraying process is the oxidation of the sprayed metal particles by the oxygen of the air flow during their transportation to the sprayed surface. This leads to the formation of a sufficiently large amount of oxides of chemical elements, which significantly deteriorate the adhesion strength and burn out alloying elements that are necessary to obtain a wear-resistant and corrosion-resistant coating. The suitability and durability of coatings during use depends on the strength of adhesion to the substrate.
In the course of the study, methods were used to determine the adhesion strength of the coating to the base – the Steffens method and methods for studying the microstructure of coatings were taken as the basis. The data was processed and dependencies were plotted.
The proposed method makes it possible to improve the quality of the resulting coating in terms of such an indicator as improvements in chemical composition. And also to influence the chemical composition by controlling the process of transfer of molten metal using a pulsating air flow.
The obtained results of approbation of the method allow us to consider it effective, as evidenced by the quality of the obtained coatings. This is due to the fact that the correctness of the formulation and solution of the problem provided adequate results. In contrast to the existing methods, the proposed one makes it possible to significantly influence the amount of harmful oxygen involved in the formation of a sprayed coating, which makes it possible to obtain a sprayed layer with the required performance characteristics. And also allows to improve its quality without significant capital costs. In addition, the issues of resource and energy saving are being addressed, since the burnout of chemical elements decreases and the air consumption during arc metallization decreases. To solve this problem, a simple design of the pulsator is proposed, which provides the ability to control the spray flow by adjusting the level of overlapping of the holes.
Investigating the fiscal motive of state incentives for innovative and investment activity
Authors: Yereshko Julia
Published: July 2021

The object of research is the state as an economic agent of innovative development. The analysis of scientific achievements on the issue of the state innovation and investment activity stimulation and the study of the state from the standpoint of the innovative development subject forms a fairly clear idea about the mechanisms of activation of them both, at the same time, the motives for the state to stimulate innovation remain not fully covered.

The state itself is not interested in stimulating the innovation and investment processes and in transition to sustainable development. This interest is mediated, as for any other economic agent, by imbalance and/or obtaining additional economic effect in the form, for example, budget expenditures reduction; tax revenues growth, managerial staff optimization, etc. And, crucialness of purely liberal nature of any controlled influence on the system mediates that state regulatory activity should be based on the economic benefit of the agent, as opposed to the political motives of nominal adherence to the generally accepted course of development.

Well-known trajectories and patterns of administrative and economic activity of the state give grounds to assume the following main economic motives for stimulating the innovation process:

– increase in tax revenues (fiscal motive);

– reducing the burden on the budget;

– GDP growth;

– increasing the country's competitiveness;

– optimization of administrative costs and management staff;

– attracting program financing and investments.

Prominent among which is the increase in tax revenues or fiscal motive. It can result in several areas:

– from the standpoint of additional taxes due to the increase in effectiveness of legal entities innovative activity – the expansion of business activities; types and volumes of sales of products and services; increase in the number of enterprises; increase in the cost of sold products; profitability, etc.;

– from the standpoint of additional taxes due to better development of the workforce – higher employment; higher wages, etc.
Analysis of cutting forces during grinding of titanium alloy and corrosion-resistant steel by diamond, electrocorundum and cubic borine nitrid wheels
Authors: Lebedev Vladimir , Chumachenko Tatiana , Bespalova Alla , Nikolaeva Tatiana , Omelchenko Yevhen
Published: July 2021

The object of research is the process of circular and surface grinding of titanium alloy and corrosion-resistant steel, namely, the cutting forces arising from mechanical processing. One of the most problematic areas in work is the selection of the required grinding modes, material and grinding wheel grain size.
In the course of the experiment, we used samples of VT8 titanium alloy and 12Х18N9T steel, on which the grinding process was studied with wheels made of various materials (electrocorundum, cubic boron nitride (CBN), diamond). The values of the cutting forces Py and Pz were obtained in the latitude of permissible modes, which are most often used in circular and flat grinding, and can reach maximum values, respectively, Py=27 N, Pz=15.5 N. The data were obtained at a low wheel speed from electrocorundum, about 15 m/s and grain size 8. By reducing the grain size of the wheel, we get the effect of increasing the energy consumption of the grinding process, due to the increase in the values of the cutting forces. If we compare the cutting forces arising from grinding with different wheels, then the following can be noted. Compared to electrocorundum wheels, when using CBN wheels, the cutting forces are reduced by 20–25 %, and when grinding with diamond wheels (despite the high wear of the diamond wheel), the effect of cutting forces is reduced by 25–30 %. This is due to the fact that cutting conditions are the most favorable for diamond and CBN grains, which makes it possible to use more intense cutting conditions.
The results of the study allow predicting the performance of the grinding wheel, reducing the energy consumption of production, and also adjusting the processing mode of the part to obtain the necessary quality indicators of the surface layer and the geometric dimensions of the part.

Authors: Vynogradova Olena , Pysar Nadiia , Drokina Nina , Lytvynova Olga , Sovershenna Iryna
Published: July 2021

The object of research is the processes of interaction of business model components for the enterprise in the fashion industry at an early stage of its life cycle, which are subject to the principles of sustainable development and distinguish the business model from the model of «fast fashion». One of the most problematic places is to determine the actual components of the business model of the enterprise of the fashion industry, working on the principles of sustainable development, rather than those that are only declared by the company itself. And also used as a tool for promotion without the actual implementation of these tools. In addition, it is important not only to establish a minimum list of such tools, but also to establish their relationship.
The study used methods of detailed analysis of the current state of the problem, based on information retrieval with extensive use of computers. Methods of empirical research (observation, comparison), method of synthesis and structural-genetic method (extraction from the complex phenomenon of such elements which considerably influence other parties of object of research, in a investigated case of tools of sustainable development) were also used. Various sources of information, databases EBSCO, ResearchGate, Jstor, secondary sources of information, company websites, analytical reports were used. As well as primary sources – interviews with representatives of fashion industry companies that implement «sustainable» practices in business processes at their enterprises (for example, Ze Kout LLC, Kyiv, Ukraine).
The scientific and practical value of the study is that the business activities of modern companies must be consistent with the goals of sustainable development stated by the UN. And development – to involve its consumers not only in the promotion, evaluation or promotion of existing products, but also in the creation of quality products based on the principles of sustainable development. This provides an opportunity to renew the cooperation of companies, update the mission, goals, and vision of business development at high quality standards of sustainable economic development. This allows to reasonably approach the construction of business on the principles of sustainable development and obtain economic effects from the introduction into production of the principles of sustainable development. In particular, product quality can be improved.
Minimization of energy efficiency barriers in the context of optimization of management decisions in the process of sustainable development
Authors: Bilous Liliia
Published: July 2021

The object of research is the socio­economic model of the country in terms of energy efficiency factors in the process of economic development. The author has adapted the taxonomy of barriers and identified a new group of barriers inherent in the socio­economic models of countries with economies in transition. Achieving the goals of sustainable development is possible by achieving overall energy efficiency, which is provided by the implemented innovative energy technologies. The ability of the studied subjects to perceive and promote innovative energy technologies is determined by the level of their economic development. When building the concept of energy efficient management, the studied subjects should take into account the exhaustion of primary resources against the background of growing needs. One of Harrington's logical functions was used to determine the level of economic development of the studied subjects. In the indicators of the particular desirability of Harrington's logical function, indicators from 0.37 to 0.8 are the potential for development, currently unrealized in the studied subjects, which is the path to sustainable development. According to certain levels of private preferences, economic agents are given recommendations on the economic feasibility of introducing innovative energy technologies. At the same time, the research process involved the identification and localization of energy efficiency barriers in the studied subjects, which expanded the analytical opportunities in terms of providing practical recommendations. Such recommendations, combined with the private preferences of the studied subjects, allowed to formulate a conceptual scheme to increase the efficiency of energy resources of economic development management. The author proposes measures: scaling of grant financing, decentralization of energy sources, introduction of knowledge, cooperation of communities and in the community, development of entrepreneurship and greening of the environment. Directions strengthen the motivation of management decisions in the context of the effective impact of energy factors on the dynamics of economic development in modern conditions and can be used in the development of current and strategic plans and programs.
Feasibility justification of implementation of a device for sorting sheep products in the context of industry development
Authors: Tsybukh Andrii , Kravchenko Olha , Pomitun Ivan , Lysychenko Mykola
Published: July 2021

The object of research is the methodology of a feasibility study for the introduction of a device for sorting sheep products. Sheep products mean sheep wool, the sorting accuracy of which affects the formation of the sale price of the final product (wool), including the size of the manufacturer’s profit, respectively, and the effectiveness and the level of economic efficiency of production. One of the most problematic areas is the subjective assessment of wool quality at the stage of pricing policy formation. This criterion is determined by a set of physical and technological indicators, which include the color of the coat, due to the degree of its melanin pigmentation or yellowing. Such an assessment, at present, is carried out with the participation of the operator, without the involvement of technical means capable of objectively registering and further providing data for the successful selection of sheep and the sale of wool.
In the course of the study, a systematic approach to the study of technical and economic processes and phenomena, an abstract logical method, monographic and empirical methods, a comparative analysis method, tabular and graphical methods, as well as a computational and constructive method for substantiating technical and economic indicators of the effectiveness of device implementation were used. The proposed analysis of the implementation of the device allows specialists at the level of enterprises producing sheep products to optimize the formation and implementation of the pricing policy. And it can also be used at the level of government bodies in determining the national policy for the development of sheep breeding and the formation of a strategy for its development. The obtained results of implementation allow:
– to increase the profit for each head of animals from the sale of better quality wool;
– to increase the level of profitability, which makes it possible to ensure the payback period for additional capital expenditures of less than two years;
– to confirm the economic feasibility of using this equipment, since the payback period for additional capital costs does not exceed two years, and the discounted payback period does not exceed the useful life.

Goddess Worship and New Spirituality in the Postmodern World: a Brief Overview
Authors: Danylova T. V.
Published: July 2021

Purpose. The paper aims at examining the phenomenon of the rebirth of the Goddess in the contemporary world. The author has used the hermeneutic approach and cultural-historical method, as well as the anthropological integrative approach. Theoretical basis. The study is based on the ideas of Carol Christ, Margot Adler, Miriam Simos, and Jean Shinoda Bolen. Originality. The rebirth of the Goddess is not a deconstruction of the God. The face of the Goddess is one side of the binary opposition "Goddess – God". Life on the earthly plane presupposes masculine and feminine dualism. However, these polarities are not mutually exclusive and mutually suppressive, but complementary to each other. The return of the Goddess to the throne and a profound appreciation of Femininity is a necessary step forward in establishing true equality and restoring lost harmony. As humanity returns to the Absolute that transcends duality, as divinity is revealed in feminine and masculine forms, and, finally, as humans get in touch with their true self, the two faces, feminine and masculine, will inevitably merge. Conclusions. Identifying herself with the images of the Goddesses, a woman develops self-awareness and self-acceptance that contribute greatly to her reintegration with a wider spiritual reality. The cult of the Goddess finds practical application in women’s lives. These are magical rituals, work with the archetypes, life-changing tours. Recognizing her right to the fullness of being, a woman overcomes rigid gender roles and stereotypes, ceases to be an object of manipulation and becomes the supreme arbiter of her own life.
From Homo Economicus to Homo Eudaimonicus: Anthropological and Axiological Transformations of the Concept of Happiness in A Secular Age
Authors: Lushch-Purii U. I.
Published: July 2021

Purpose. The paper is aimed to explicate a recently emerging anthropological model of homo eudaimonicus from its secular framework perspective. Theoretical basis. Secularity is considered in three aspects with reference to Taylor’s and Habermas’ ideas: as a common public sphere, as a phenomenological experience of living in a Secular Age, and as a background for happiness to become a major common value among other secular values in the Age of Authenticity. The modifications of happiness interpretation are traced from Early Modernity till nowadays. The preconditions of the contemporary appeal to Aristotle’s eudaimonic theory of happiness are elucidated. The main characteristics of homo economicus anthropological model and reasons for its collapse in the contemporary world are analyzed. Specificities of the contemporary interpretations of eudaimonia are described with reference to the works of MacIntyre, Haybron, Hamilton, Kekes, Melnick, and others. A moral foundation and a behavioral strategy of homo eudaimonicus model are expounded and the role of this model in the life of a contemporary individual person and society is revealed. Originality. For the first time in the Ukrainian philosophical discourse, it is shown how secular ethics enables the rise of a new homo eudaimonicus model within a sphere of secularity; and it is argued that homo eudaimonicus is the result of overcoming the values crisis. It is revealed how homo eudaimonicus along with being descriptive becomes also a normative model of a new effective behavior strategy of a contemporary person facing the current social, economic, political, and environmental challenges. Conclusions. According to the contemporary interpretation, happiness as eudaimonia is a combination of the good life and the meaningful life; it is a human flourishing in this world (saeculum) through the accomplishment of a person’s life plan in the sphere of secularity. Homo eudaimonicus manifests the overcoming of values crisis and the rediscovery of purpose and meaning, this time on the secular basis. Homo eudaimonicus implies the realization of a person’s project of a happy and fulfilling life through moral behavior and socially useful activities.
From Anthropocentrism to Care for Our Common Home: Ethical Response to the Environmental Crisis
Authors: Muliarchuk Y. I.
Published: July 2021

Purpose of the study is explication of ethical and existential conditions of realization of human responsibility for the protection and recreation of the environment on a scale of the common world with all the other living beings. The crisis of the environment is the crisis of human morality. For responsible environmental management, it is necessary to form the ecological consciousness of society and reinterpret the anthropocentrism on the ethical foundations. The theoretical basis of the research is the analysis of ethical and existential dimensions of understanding of the human environment ranging from the sphere of the home and the natural environment to the dimension of the common world of people and all the entities. The work clarifies the genesis of the concept of home from the ancient "oikos", household to the idea of home as a "hub", a base for mental and physical mobility in the contemporary technosphere. Correspondent to the transformation of the living world of mankind is the concept of communication and universal discourse of norms and values of human coexistence of J. Habermas, К.-О. Apel, D. Böhler, W. Kuhlmann, and others. The domain of the ecological consciousness and behaviour also requires motivation at the level of human feelings, beliefs, and convictions, which is represented by the philosophic and religious thought of H. Jonas, O. Leopold, K. M. Меуеr-Abich, A. Naess, the pope Francis, and others. As the result, the study proves the relevance of the concept of care about the common home based on the recognition of the value of the existence of all beings. Originality. The study explicates the genesis and meaning of the ethos of the common home with values of love, care, openness, solidarity, freedom, and responsibility which is proved to be the ethical and existential condition of the solution of the environmental crisis. The traditional anthropocentrism is reinterpreted towards the duty of people to be the centre of the responsibility for the existence of all beings that requires both reason and care. Conclusions. The ethics of care for our common home completes the moral duty of people as providers of the universal discourse who represent the interests of all beings. Concern for the preservation of the human environment and of all creation makes it possible for humanity to realize its universal responsibility in the world. The contemporaneous science and religious thought modify anthropocentrism to the holistic ethical understanding of human’s mission to be responsible for all beings.
Corporate Nietzsche: Assessing Prospects of Success for Managers with Master and Slave Moralities
Authors: Faisal A. , Aleemi A. R.
Published: July 2021

Purpose. Nietzschean proponents classify people into seemingly two distinct groups: those possessing 'Master' moralities and those with 'Slave' moralities. Each type of person is characterized to have certain qualities, traits, ideologies, and methods of dealing with everyday situations. This paper attributes these moralities to the personnel working in the corporate sector of Pakistan to observe their prospects of success. Originality. A specialized survey instrument was designed to gauge different Morality Types of the study subjects by calculating a Morality Quotient. The respondents were then categorized into three categories possessing, Slave, Master and Neutral or Mixed traits. These traits are then contrasted to the position(s) held by the subjects to see which morality type was more prevalent in higher management levels and whether the association was significant. Conclusions. Our results prove to be contradictory to common wisdom and shows that despite the leadership-like qualities of those with Master moralities, the proportion of those with Slave moralities was significantly higher at senior management levels of the corporate sector in Pakistan. Moreover, a trend of declining Master morality traits is observed with the rise in managerial level. In addition, an association between work experience and Morality type was also observed indicating adaptability of cross morality traits with increasing job experience. These findings are in line with the increasing focus on democratic and adaptable leadership instead of autocratic leadership styles in contemporary organizations.

Purpose. The staged connections of the stringers of railway bridge track-way have the simplest design, but some design flaws result in numerous defects. The purpose of this work is an investigation of the previously proposed methods of strengthening the support node for the stringers of the track-way of a staged communication, as well as investigation of the work of the reinforcement proposed by the author. Methodology. The author analyzes the condition of metal bridges operated on the railway. It was found that the decisive element in determining the load capacity of the entire bridge are the stringers of the track-way. To achieve this goal, the author analyzed the stress-strain state of the support node of the stringer on the cross-bar without and with reinforcement using the finite element method. The discovered rational parameters of the proposed reinforcement unit. The calculations were performed in Selena software. Findings. Stress-strain state of the connection point of the stringers with the floor beamsnode on condition of their staged position was obtained and analyzed. The author selected the rational parameters of the reinforcement elements of the stringer support node for the staged communication and analyzed stress-strain state of the new connection node of the stringers with the floor beams at their staged location based on typical spans of Proiektstalkonstruktsii LLC (PSK). The analysis shows that after the proposed reinforcement, the maximum stresses in the horizontal legs of the flange angles of the stringers and floor beams, which destroyed the structures, decreased by 43–73%. Originality. The work analyzes the stress-strain state of metal stringers of the track-way of the staged location taking into account the joint work of stringers with load-bearing trusses, as well as the stress-strain state of the proposed reinforcement of the support node of metal stringers with the identification of rational parameters. Practical value. This method of repair with reinforcement is recommended as the most rational for a bridge over the Inhulets river at 109 km of the Verkhivtseve – Dolynska Railway (contract No. 94/2011–TsTekh–177/2011–ETU dated 09/30/2011). Based on these results, a patent for utility model No. 109806 dated 09/12/2016 was issued.

Purpose. The main purpose of the authors is to define and methodically substantiate the ways to increase the efficiency of intermodal passenger transportations with the involvement of high-speed trains as an auxiliary mode of transport in terms of sea and river tourism. Methodology. In the process of research the following was used: the method of factor analysis – to determine the factors influencing the attractiveness of tourist travel using high-speed trains as ancillary transport; method of skipping stops – to increase the efficiency of using high-speed trains as an auxiliary mode of transport when making tourist trips; methods of construction and training of generative-adversarial networks for the formation of model of passenger flows forecasting, on the basis of historical data of multivariate time series; method of genetic algorithms – to optimize the model of mixed-integer programming, which allows obtaining the optimal scheme of high-speed trains on the line. Findings. In order to preserve the attractiveness of tourist travels and increase the route speed of trains, it is proposed to improve the technology of planning their work based on the method of skipping stops. A mathematical model of mixed-integer programming has been formed, which simultaneously provides the attractiveness of tourist travel and profitability for railway operators. To prepare the initial data, a method for forecasting passenger flows based on multivariate time series has been developed. The optimization procedure of the generated model was implemented in the form of software in the Matlab language. Originality. The method of skipping stops, which was first used to improve the technology of intermodal passenger traffic, was further developed in the work. An original method for predicting passenger flows based on multivariate time series using a modern model of generative-competitive neural networks is proposed. Practical value. The obtained results are aimed at improving the methodological approaches to the formation of modern technologies of intermodal passenger transportation and the realization of the potential of high-speed rail transportations as a basis for the comprehensive development of tourism.

Purpose. Based on the research work of units and parts of rolling stock undercarriage in transient modes of emergency situations it is proposed to optimize the sequential placing of peripheral contactless devices for technical control of locomotives and cars on railway lines. Methodology. Investigation of transient processes of temperature increase of faulty axle bearings of locomotives and cars during remote technical diagnosing allows one to organize theory and hardware construction of the peripheral systems for testing the rolling stock on the move. Automatic control of the technical state of the rolling stock on the move – the last and in some cases the only possible process step, which allows revealing unacceptable defects in rolling units and thereby prevent emergencies in railway transport. Findings. Based on the research it was proposed a solution to the optimization problem of placing peripheral control devices of rolling stock when moving according to the criteria of the linear and exponential nature of heating defective axle boxes of wheelsets and other units of undercarriage. The risks of train stop on the railway line because of the erroneous classification of normally heated axle boxes as overheated, as well as the consequences of classification of overheated axle box as normally heated axle boxes were evaluated. Originality. Optimization model of placing peripheral control devices based on probabilistic criteria for evaluating the degree of permissible risk that, at a minimum, should not be exceeded during the transition to control technical means. A functional block diagram of test hardware diagnostics for the wheelsets when determining the gradations of digital indicators of defects was proposed. Practical value. The value of the results obtained lies in the improvement of a method of placing technical control peripheral devices and diagnosing rolling stock when determining the distance between the control stations in the same direction and organizing tracking modes for railcars with developing defects. From a technical point, reduced error probability is directly related to traffic safety and diagnostic algorithms.

Purpose. The research is aimed at developing a mathematical model for determining the risks in railway transport during the diagnostics of axle boxes of freight cars, which will provide an assessment of traffic safety in the case of freight transportations. Methodology. To develop a mathematical model for determining the risks in railway transport, a continuous static model of the dependence of the level of individual approach of service personnel on the level of common interests (crew, shift) was used. Three types of dependencies were considered: optimistic, neutral, pessimistic. Findings. A mathematical model has been developed that allows assessing the risks and the level of train traffic safety during the diagnosis of axle boxes of freight cars, as well as determining further measures to reduce risks. In the process of assessing the level of individual approaches and general interests of a particular railway subdivision during maintenance and repair of the axle box of freight cars the variants for the limit possibilities of this subdivision were considered. At the same time extreme values for equilibrium distribution, for a case of dominance of maintenance and for a case of dominance of repairs of freight car’s axle box were established. Originality. For the first time, a mathematical model of risks in railway transport was developed, which is formed during the maintenance and repair of freight cars. It allows determining the level of traffic safety during freight transportations and outlining further measures to reduce risks. The method of studying the efficiency of the system of maintenance and repair of the axle box has been further developed, which, in contrast to the existing one, establishes the  dependence  of the number  of maintenance of axle boxes  on the  number of their repairs  in operation  and  will
increase traffic safety. Practical value. The application of the obtained mathematical models of risks in railway transport can reduce the risks during the diagnostics of axle boxes of freight cars in order to increase the local or general level of train traffic safety.
