PROSPECTS OF SMALL HYDROPOWER PLANTS IN THE PIEDMONT AND MOUNTAIN STREAMS
DescriptionThe article reveals the advantages of low energy in comparison with other renewable energy sources. It is shown that broad prospects are visible for small (100 - 1000 kW) and micro hydropower plants (up to 100 kW) when used in the foothill and mountain areas. At the same time, the construction of hydropower plants of sleeve-type has improved the operational and technical characteristics, among other types of small-scale power plants. The article presents main analytical expressions for calculating hydroelectric power generator and it has built graphic dependences for the power generator of pressure and water flow. To improve the performance of small hydroelectric power plants we have proposed using unregulated water turbine and non-contact induction generator in their construction, thus, we could stabilize voltage and frequency directly by the frequency converter. Depending on the requirements of consumers to power supply reliability and electricity quality, we have offered several options for structural and circuit solutions of autonomous systems of electrosupply, made using small hydroelectric power plants. Thus, we can greatly enhance the efficiency of such systems if they are used with other types of renewable sources, such as windfarms or solar power plants

Description
This article describes the opportunities and prospects for the deployment of decision support system for the adequacy of the level of lending to small agricultural enterprises in the cloud environment. It reveals the shortcomings in the existing automation of small businesses, and therefore the necessity of developing a system to enable managers to quickly and correctly calculate the amount of required loan funds. The developed system has the ability to work remotely due to the lack of binding the user to a specific personal computer. It is implemented through the development of a DSS using cloud computing, in which computer resources are provided to the Internet users in the form of "online service". The article describes the architecture of popular models and cloud Webapplications; after that, it was concluded to use the Saas model with Multi-Tenant-mode support in the model development. The study provides an overview of the DSS functioning in the cloud. It has noted the main features of the software implementation of the system relating to the use of cloud technologies. We have calculated the cost of placing an application in the cloud via the online cost calculator called Microsoft Azure. We have also performed a preliminary assessment of the payback period of the project implementation of DSS. It is concluded, that this technology would be competitive at the software market

Description
The analysis of social and economic development of countries in the conditions of the globalization of the world economy which is carried out with the use of thermo-dynamical model showed that interaction of the open economic systems standing on different levels of development can lead to absorption or destruction of one systems by others that finally will lead to "thermal death" in economy (stagnation). The closed economic systems can communicate with other countries by means of international trade. Less developed countries can't compete with industrially developed states and will inevitably get under their influence. The isolated economic systems can develop only in the presence of domestic market, resources and rigid social structure. Introduction of the anti-Russian sanctions and other external factors led to restriction of the influence of the foreign capital. Innovative activity in economy and strengthening of government institutions might be observed as a result. The thermo-dynamical model shows that partial isolation of the developing economic system possessing sufficient production and scientific potential leads to stabilization of its structure and growth of the innovative activity

ACREAGE AND YIELD OF WINTER BARLEY IN THE MAJOR REGIONS OF GROWING
06.00.00 Agricultural sciences
DescriptionThe article presents a comparative analysis of national economic importance of winter barley in relation to other crops. The advantages of winter barley in a number of factors have been observed. The information about acreage under crop and gross yield of this crop is presented in an article in the form of tables. The authors have studied such important factors as a dynamics of acreage of crop yield in the main regions of cultivation. Against the overall negative dynamics of sown areas, they noted a clear increase in 2013. An analysis of grain yield of winter barley in the main regions of cultivation by year has been presented graphically. Special attention was paid to the Southern Federal District and the Krasnodar Territory in particular as a major producer of grain of winter barley. The analysis of yields in the major regions of cultivation of winter barley showed a clear advantage of the Krasnodar region. The index of the average grain yield of winter barley cultivation in this region for the period from 2003 to 2008 has been shown. Moreover, the article has presented the role of sorts in increasing the yield grade. We have also highlighted the issue of selection of winter barley in our country. The desirability of increasing the production of winter barley in the Russian Federation has been noted as well

PRECONDITIONS AND FEATURES OF DEVELOPMENT OF “MICRO-CLIMATE” MANAGEMENT INFORMATION SYSTEM
DescriptionThe article investigates the experience of implementing automated control systems, which indicates that at the system design phase, it is difficult to choose a single criterion of control. Therefore, in the control system it should be possible to quickly set the criterion during operation, and methods of assignment should clearly reflect the agronomic, economic and technical requirements for the system. Thus, modern control system should allow to define not only one of the above control criteria, or a combination, but any other arising in the production process, providing agronomist-technologist opportunities in choosing a method of maintaining temperature and humidity conditions in the greenhouse. Greenhouse is a fastpaced environment and the state largely depends on the intensity of sunlight, humidity, direction and wind speed, the number of fertilized soil and its humidity. Competent and correct management of these parameters is a complex task and involves certain costs, but in the end allows you to benefit many times greater than the costs. The developed system called "Microclimate" will have a positive effect on any hosted sites, as it allows to increase energy efficiency and reduce fuel costs for heating greenhouses, electricity, water

Description
The article considers prerequisites for the development of complex software and tools for data analysis, modeling, forecasting and management decision making in the management of IT-projects. System of decision support can facilitate the work of heads of enterprises and increase its efficiency. They significantly accelerate the solution of problems in business. In the organization, there is a software complex, which suggests that the transmission of information about incoming orders and deadlines for every Department and information on the implementation of the orders of the head is performed via the software package. Using software system, the client leaves a request for the execution of services. The Manager sends a request to the appropriate Department. Units, in turn, convey information about the status of the application via the software package. The software package provides fast remote bilateral communication in electronic form between the client and Manager and between Manager and the departments. In a company, the head and head of sector perform the coordination of work in implementation of IT projects. However, there are a number of human factors that make people cannot keep track of the timely execution of all requests from subordinates

USING GAME THEORY IN THE EDUCATIONAL PROCESS
DescriptionThe article is devoted to the use of game theory in the educational process. Subject of research is the educational process. The authors have studied the game in normal form where participants are the teacher and the student of the university. Different treatment of the student and the teacher to pass the test are strategies of the players. Construction of a matrix is based on the base of sequence preference on multitude of outcomes. The solution of this task is implemented in two stages: formulation of the problem and solution. As an interim solution the authors considered the winnings of players 1 (the student) and 2 (the teacher). As a final solution is considered the situation satisfying both of players: player 1 (the student) and player 2 (the teacher). The results obtained in this research will help to find ways to improve the educational activity. The actuality of the research is explained with the fact that the institutions of the highest education are trying to participate actively in the development of personality of students nowadays. While effective teaching in the university, there is a paying more attention to this problem. Focusing on the forming of personality in the process of education makes the generation of an orientation mission of every student at the university one of the most important advances

PRINCIPLES OF ORGANIZATION AND OPERATION OF COLLECTIVE TAXI
DescriptionThe volume of transportation of passengers by taxi is 6-9% of the total traffic of all kinds of public transport depends on the size of the settlement. The main purpose and the advantage of a cab is providing services for the transportation of passengers on the route, appointed by the customer, around the clock work and comfortable travel. To unload the transport system of the city, especially during peak hours, it is proposed to introduce a new type of operational-servicing passengers - a collective taxi. It is designed to transport multiple passengers traveling in the same direction, but with different destinations landing, while the fare is much lower than in a normal taxi. In organizational sense, collective taxis can be a unitary taxi company with the official standard structure and the quantity of the workers or a division of the taxi park of the city
