SOURCES OF UNINTERRUPTED AND AUTONOMOUS POWER SUPPLY
DescriptionThe article describes the main block diagrams of three types of uninterruptible power supply: backup; interactive; double conversion. The main functions are: the function backup or emergency source of electrical power; the function of protective devices (from an overload currents and short-circuit); improving the quality of the power supply voltage. Alsoб we have disclosed the features of the advantages and disadvantages of uninterruptible power supplies three groups: Off-Line / Stand-By / back-up UPS (passive - reserve); Line-Interactive (line interactive type); On-Line. The article discloses new approaches to structural and schematic-based uninterruptible power supply, including at use of renewable energy, so that the failure of one of the sources does not lead to exit from the operation of the entire of power supply system. As a rule, such systems are built on a modular principle. It is shown that now for remote users from external networks is advisable to apply a system autonomous power supply, representing the totality of sources and converters of electric power, ensuring uninterrupted power supply to consumers. We have presented a typical structure of autonomous systems and given an option of the block diagram of the system and are given explanations and principles of its work. Significantly improves performance reliability of autonomous systems using the modularity of its main functional units. In addition, to increase the efficiency of the system can be through the use in the construction of transformers with static converters rotating magnetic field. To improve the weight, which is important for the transport systems, it is necessary to use links with the intermediate high-frequency electric power conversion in static converters

Description
The article reveals the basic concepts, purpose and classification of HRM systems used to manage the organization's staff. The analysis of the international and Russian market of HRM-systems and selected alternatives (seven information systems) of this class focused on the Russian practice of large and mediumsized businesses has been performed. The process of implementing an information system involves selecting the system that best suited to the needs of the business. For this purpose, there were developed evaluation criteria of information systems and their importance for the company. This stage of research was conducted through a survey of experts from among the University staff and practitioners. As a result, we have obtained the matrix of evaluations of alternative information systems of HRM and selected class "1C: Salary and personnel management 8". Research demos of the selected HRM system allowed developing a functional model, presented in the form of complex diagrams of cases of modeling language UML 2.0. The developed diagrams clearly reflect the allocated subsystems and their functions, as well as the relationship between the actors of the process and system functions. Summarizing the experience of implementing similar systems, we composed a smartchart showing the main stages of its implementation. The results have practical value and can be used by companies of the considered business segment as specific recommendations

USING MECHANISMS OF FORMALIZATION OF DIDACTIC CONTENT FOR SKILLS DEVELOPMENT MONITORING
DescriptionThe relevance of an effective system of professional development for science-intensive and high-tech industries demonstrates not only the need to promptly respond to the global challenges of the modern economy, but also the presence of professionals able to reform the Russian economy in conditions of adverse effects of the sanctions. The leading role in these processes is assigned to highly qualified staff, which is formed in the process of training specialists within the system of continuous professional education and training (CPEandT). Expansion of the use of the system of CPEandT in modern educational technology (MET) opens new possibilities for advanced training and monitoring of this process by formalizing mechanisms of didactic content. We have developed specific mechanisms of formalization of the bestknown relationship between the information flow of didactic content and scope of knowledge of professional disciplines plan of professional development, as well as the possibility of their use for the monitoring of the process. The article discloses mechanisms of formalization of the process of professional development for science-intensive and high-tech industries, which will actively contribute to their successful implementation and monitoring

INTERVAL SPANNING TREE PROBLEM ON A TOPOLOGICAL CRITERION
01.00.00 Physical-mathematical sciences
DescriptionThe article presents the problem of spanning trees with topological criteria and interval scales. We have introduced relationship preferences and incomparability to find the complete set of alternatives in the case of interval scales. The base for mathematical calculations is interval mathematics

Description
The article deals with the problem of oil-contaminated waste utilization. It has suggested the ways of technological advancement taking into account the principles of BAT. The analysis of the legal framework for BAT in Russia and the EU is carried out. The features of the state regulation in the field of BAT and the main approaches to formation of a complex of measures for transition to principles of BAT are considered. It has described the innovative approach to the development of waste treatment technologies that are best and available from an environmental and economic point of view. It has identified limiting parameters affecting the efficiency of waste utilization and the suitability for use as secondary material resources, particularly in the construction industry

Description
The article describes a new approach to the assessment of the economic system. The authors propose to assume that the system grows, if its share in the world production increases. For the qualitative assessment, we have offered to analyze the dynamics of growth of exports of products with high benefit to the foreign countries, which include engineering goods, defense, manufacturing materials. On the world market of hightech products, we have the stiff competition and the growth of exports of domestic products with high benefit indicates high level of innovation. Based on the analysis of available statistical data, we revealed a correlation between exports of innovative products, the volumes of financing research and development and foreign direct investment in the national economy. It was determined foreign capital has a negative impact on exports of products with high benefit. The authors proposed a two-factor regression model, which allows you to make short-term forecasts and allocate resources. The study showed that despite the ongoing economic sanctions and unsuccessful economic reforms in the past, Russia has a high potential for innovation, which is activated when reducing the influence of foreign capital. Attempts to isolate the Russian economic system led to the mobilization of resources and the growth of innovation activity of domestic business

Description
The article examines the main trends in foreign direct investment (FDI) in the Russian Federation and the Republic of Tatarstan, as well as it analyzes the structure and the dynamics of the inflow of foreign direct investment in Russia and the Republic of Tatarstan. The emergence of new investment projects and the increase in production volume are due to receiving investments in the country and in the region. Unfortunately, there are still problems in the way of receipt of investments in the Russian economy and its subjects, which are formulated in the article and that require solutions. On an example of the economy of the Republic of Tatarstan we have analyzed an inflow of foreign direct investments for 2010 – 2013, as well as the dynamics, sectoral and geographical structure of income from investments. We consider the strategy of attracting foreign investors to the region on the example of the Republic of Tatarstan. The article proposes key measures aimed at improving the investment climate, improving the competitiveness of industries. All these activities will positively contribute to the inflow of foreign investments into the economy of the country and its regions. Foreign direct investment can serve as a mechanism for increasing Russia's competitiveness in the global economy, and help to integrate into the international economic system more active
