Reduction of non-renewable sources of energy and the ecological state of metropolises have become the cause of the search for optimal solutions for introduction of energyefficient and environmentally friendly technologies for urban bus transport, which is thepurpose of this work. A review of environmentally friendly buses has shown that electric buses (electrobuses) are the most perspective. However, rapid replacement of all the buses with electrobuses is impossible because of their high cost. A comparative analysis of theoperating costs of different types of buses of the same destination and class has been carried out in order to choose the optimal variant. Thus, one route of 4.23 km in length was chosen in Kharkiv (Ukraine). Experimental and calculated data showed that aminibus converted into an electrobus is the most acceptable means for urban passenger transportation. Ultra-capacitors are suggested as an energy source. The conceptualdiagram of the model of such a bus is presented and the technical requirements for itscomponents are determined. The data and proposals are useful for Ukraine and for countries with low economic development that cannot quickly replace old diesel buseswith new, environmentally friendly, electrobuses. The results of this work are the basisfor further research and development.

This paper investigates the ways to solve the problem of additional street lighting using innovative road-pavement for green energy production. The aim of this study is to offer innovative solution of road-pavement which enables to produce green energy for additional lighting of streets using LED technologies with acceptable monitoring. The design of sustainable road-pavement is presented in the article. Its functional capabilities and the principle of operation are described. Such roads can be considered as the alternative decentralized sources of energy, because they generate electricity not only for their own needs, but for other consumers. The estimation of generation of electric power by the system of sustainable road-pavement has been made. The section of road 7.5 m wide and 1 km long is capable of generating about ~1.8 MW of electricity per one day. The authors have made this research aiming also to initiate the debates in the scientific world and society about the significance of such kind of solutions for sustainable development.

The analysis of existing alternative power source equipment that convert other types of energy into electric power was carried out. This study proposed a technical solution for the design of the power generating tile or step, which converts the kinetic energy of press into electric power and accumulates it. The operating principle of the power-generating tile is described as an alternative, decentralized source of electrical energy. The experimental research of the developed device was conducted and the method of conversion of kinetic energy into electric power improved. A correlation method that allows conducting analysis and calculation by quantitative indicators of the generated electricity from press was presented. The proposed device can be used as an alternative source of electricity in places with great foot traffic. The device has small overall dimensions and can easily be set up in various types of aisles, stairs, and integrated into the network of LED lighting.

The increasing importance of continuingly complex Cyber-Physical Systems (CPS) challenges and encourages universities worldwide to organize up-to-date CPS oriented educational programs. The Erasmus+ project “CybPhys” aims to support CPS oriented educational programs in Belarus and Ukraine. We put forward a hypothesis that the educational situation, training opportunities, situation of the labor market, and general economic development are related to each other and can vary depending on the region. In order to validate our hypothesis and to provide input to curricula modernizations, an in-depth study in the form of surveys was conducted in the years 2019–2020. The results of the study showed that the differences between the perceptions of stakeholders in different regions of one country were more significant than the deviations between the global evaluation marks obtained from Belarusian and Ukrainian respondents. In order to increase the synergy of the CybPhys partners, the transdisciplinary and T-shape skills approaches are introduced to the education programs of the partner’s universities. An innovative ICT based teaching and learning environment and associated teaching methodologies will be developed. The research provides valuable input to the development of industry and research-oriented cross-domain study programs in Cyber-Physical Systems focused on the needs of Belarusian and Ukrainian industries.

There were analyzed current modernization areas of locomotives powerful diesel generator sets (DGS). It was determined that to improve the efficiency of the DGS, it is necessary to modernize the speed and load controllers. Three methods of their modernization are considered. It was determined that the most effective method to increase the profitability of locomotives is the introduction of electric speed and power regulators with the ability to control the start of fuel supply. Also, a significant increase in efficiency can be achieved by reducing the frequency of idling, but it is necessary to take into account a number of limitations. Theoretical studies have shown that the application of the proposed methods to reduce the average cost of fuel per unit of time in the thrust mode for steady-state and transient conditions, the efficiency of a diesel generator can increase by 4-5%. A huge impact on the final indicators of reducing fuel consumption in operation has the skill level of the staff and the technical condition of the diesel generator set, as well as the degree of workload. The results of theoretical studies were confirmed by tests results that had been carrying out under actual operating conditions for a year in Kharkiv, Ukraine.
