01.00.00 Physical-mathematical sciences
Description
The article is devoted to the solution of the problem which is the fact that on the one hand, the rating of Russian universities is in demand and on the other hand it hasn’t been created yet. The proposed idea of solving the problem consists in the application of domestic licensing of innovative intelligent technologies for these purposes: we have suggested using an automated system-cognitive analysis (ASC-analysis) and its software tools – the intelligent system called "Eidos". These methods are described in detail in this context. It is proposed to consider the possibility of applying these tools on the example of the Guardian University ranking. The article discusses its private criteria (indicators of universities). We specify the sources of data and the methods of their preparation for processing in "Eidos" system. In accordance with ASC-analysis methodology the article describes the installation of "Eidos", the data input into it, and the formalization of the subject area, synthesis and verification of models, their display and use to solve problems of assessment of the Guardian rating for Russian universities and research object modeling. It also discusses the prospects and ways of development of the integrated rating of Russian universities and operation of rating in adaptive mode. We have also specified the limitations of the proposed approach and the prospects of its development

INSTITUTIONAL INFRASTRUCTURE: ESSENCE AND CONTENT
Description
The article discusses the concept of "institutional infrastructure" and clarifies its essential content in relation to market cars. In terms of the industry market the main purpose of the institutional infrastructure is achieving the maximum economic benefit within limited resources. The main tasks that need to be solved in order to achieve this goal were formulated. We have developed and proved structurally-logical chart of the elements of the institutional infrastructure. The content of the institutional infrastructure of the car are presented and justified. The analysis condition of the car market’s institutional infrastructure showed the problems associated with the state of institutions which have an impact on the functioning of the car market. Measures to stimulate the car market does not cover entire sector as a whole, and imported institutions do not give the expected effect because of inconsistency formal and informal elements of the institutional infrastructure. Presented assessment of the institutional infrastructure of the car market confirms the dependence of the state of the industry market cars from institutional infrastructure. Only reforming the institutions at all levels of the industry, from production to car sales can have a positive effect on the industry. Changes in the institutional infrastructure should be focused on improving the competitiveness, stability and independence from external factors

Description
A thermal physical and mathematical model of laser cladding with TiNi on steel was developed which allows us to monitor the formation of the structure and the properties of the surface layer. A description of the model included assumptions and simplifications; analysis of the energy balance; numerical modeling of thermal processes; evaluation of the temperature distribution; experimental verification of the obtained solutions. The composition of the steel and TiNi alloy was examined as a two-layer material with different thermal characteristics. The energy balance of the system was described with a heat equation in a three-dimensional form. The main channels of the radiation energy costs were taken into account: absorption surface of the product, loss owed to the reflection surface, energy absorbed by the coating which did not come down to the base material. To solve the differential equation of heat conduction we used the Fourier integral method. In assessing the temperature distribution we have reviewed a dimensional problem when exposed to a point source of the Gaussian distribution in a pulsed mode. Computer calculations used MathCAD graphs of temperature changes at different depths of the TiNi layer and the steel substrate. The results obtained allowed us to develop the recommendations for optimizing the technological parameters of laser cladding of TiNi. The simulation of thermal processes significantly reduces the time and resources required to develop the technology, allowing prediction of the quality of the surface layer during the development of the technology and promoting the adoption of efficient technical and technological solutions

NEW POSSIBILITIES FOR RISING COMPETITIVENESS OF THE KRASNODAR REGION WINEMAKING
Description
In Russia, the demand for quality grape wines is growing. While the demand is met mainly by import of grape wines. Russian wines are little known, and therefore are not claimed yet. New directions for improving the competitiveness of Krasnodar region winemaking, taking into account the use of the existing opportunities in the region are proposed in the article. Many new facilities of sports, cultural and residential destination, infrastructure, significantly upgraded hotels, motels, etc. are built in the Krasnodar region in connection with the two Olympic Games in Sochi. Sochi has a year-round opportunity to take high-level participants in the various international and national, cultural events, sporting events, etc. In addition, the Krasnodar region has a Black Sea resorts and the Sea of Azov. Segment HoReCa in the Krasnodar region is represented in significant numbers, and requires a high level of service. It means that a completely new direction for the marketing of wine products in large quantities on a regular basis, especially at the local market, appeared. The program of segment HoReCa exclusive service, the implementation of which can be carried out with the active participation of regional authorities is proposed in the article. The most complete and effective implementation of this trend is possible as result of the creation of the wine cluster in the region. The public-private partnership may be the mechanism of the interaction. Overall, the wine industry is very promising, has considerable potential for development both within the regional market and the subsequent prospects of manufacturers on the international market

Description
A method is considered, on the concrete example of hothouses of type of 6D, for calculation of bearing strength of overhead and lower belts of farms of coverage. The vital necessity of deep analysis of the question of bearing strength appeared in the light of satisfied mass erection of hothouses constructions of which are bought in the countries of Near East. However, a simple transfer of constructions of hothouses made in the countries of Near East can not be successful on the territory of the Russian Federation. These constructions of hothouses can not be maintained in some conditions, according to service exploitation, like snow loadings, in other cases - wind loadings, and in third case, a construction can collapse without visible reasons. The conducted successive static, dynamic and seismic analysis, executed due to the normative documents and the norms of supplier operating on the territory of the Russian Federation, in attachment to the real sections of bearings structural elements, allowed us expose the stated below percentage of the use of the examined elements of constructions. Lower belt of farms of coverage: on the norms of the Russian Federation, on the first maximum state percent of the use – 395 %; there is a percent of the use on the second maximum state – 999 %; on the norms of the Russian Federation taking into account loadings of supplier, on the first maximum state percent of the use – 339,3 %; there is a percent of the use on the second maximum state – 999 %. Overhead belt of farms of coverage: on the norms of the Russian Federation, on the first maximum state percent of the use – 495,2%; there is a percent of the use on the second maximum state – 361,4 %; on the norms of the Russian Federation taking into account loadings of supplier, on the first maximum state percent of the use – 150,8 %; there is a percent of the use on the second maximum state – 146,2%. Analysis presented allows establishing that at the load of overhead and lower belts of farms of coverage of hothouses, by combinations of loadings characteristic for the place of location of hothouse of type of 6d, their bearing strength, and buildings in general can not be provided

STANDARD OF LIVING OF THE POPULATION OF THE KUBAN REGION
Description
Poverty is a pressing problem in the scale of the national economy, and within regions. In agricultural regions a large proportion of the population is engaged in agricultural production, where the pay is low. In such regions the scale of poverty are significant. Poverty also has negative social potential. Low standard of living remains one of the main obstacles to increasing the birth rate and to the solution to the population problem. One of the main indicators of quality of life is the size of per capita income. This indicator allows us to compare the standard of living of the populations in the same region and between subjects. To assess the level of material security in Russia we often use two indicators: a living wage and the minimum consumer budget. The concept of “poverty” and “living wage” used in the world as equivalent. The dimensions of these parameters are determined by the value of the minimum allowable limits of use below which normal human development is impossible. The author conducts an analysis of selected indicators of living standards of the population of the Krasnodar region. One of the areas of analysis appears characteristic of households with wealth lower than subsistence minimum. Poverty is directly related to the unequal distribution of income and property. The article analyzes the socio-economic differentiation of the population of the Kuban region

LABORATORY-FIELD TESTS OF EXPERIMENTAL DIGGER WITH MODERNIZED DIGGING THE WORKING BODIES
Description
Potatoes in our country are one of the most cultivated cultures in agriculture. The most time-consuming process in the production of potatoes is harvesting. Currently for potato harvesting potato harvesters or diggers are used. Existing machines are not sufficiently well-behaved in adverse operating conditions such as the high and low humidity. Quality of work of the units and devices of potato harvesters depends on the digging working parts. In the process of potato harvesting up to 1000 tons of heaps from 1 hectare go through the units of the machine, which includes plant residues and dense soil out of row spacing. To eliminate or reduce the impact of this lack, on either side of the coulter we set cutting discs which prevent ingress of heaps out of row spacing. However, due to the imperfections of the design they are slipping during operation what causes accumulation and enhancing traction resistance. Based on these facts, the work on improving the digging working parts in the actual and future challenges for the country's agriculture

VIBRATION TECHNOLOGY WITH A LARGE AMPLITUDE OF PARTICLE MOTION OF FEED COMPONENTS
Description
The article has revealed the contradiction between the way of technological impact and the means of implementation of technological transport in existing processes of feed preparation. There has been shown the possibility of eliminating this contradiction by menus of completely new technological equipment on the basis of relative screw drums and the opportunity to improve their productivity. There are no exciters in the offered design of vibrating machines. There is no need for them because the move mend of mass loading particles is provided by the original constructions of relative screw drums committing a rotary motion around its own axis. For implementing of feed preparation process the geometry of the relative screw drum and its dynamism must be individual: the shape, spatial orientation, the impact of forces providing feed components particles simultaneously with rotational-translational and vibrational motion. In the result, the continuously running through the inner cavity of the relative screw drum particles of feed components perform rotational-translational movements with super imposed vibrations inside this drum, due to this process the particles of feed components are mixed intensively

ESTIMATION OF BEARING STRENGTH OF BRACES AND STRUTS OF FARMS OF COVERAGE OF 6D TYPE HOTHOUSES
Description
The method of estimation of bearing strength of braces and struts of farms of coverage of hothouses is presented in the article. The deep analysis of the question of bearing strength appeared in the light of mass erection of hothouses, especially in the South Federal district, the construction of which had been bought in the countries of Near East. However, simple transfer of the constructions of hothouses made in foreign countries can not be considered as rational on the territory of the Russian Federation. The constructions of hothouses in most do not maintain exploitation even in one winter, when the considerable snow loadings are, and wind as well. The necessity of bringing of clarity for the folded situation became more obvious. Conducted successive static, dynamic and seismic analyses, executed upon the normative documents and due to the norms of supplier operating on the territory of the Russian Federation, in attachment to the real sections of bearings structural elements, allowed to expose the stated below percents of the use of the examined elements of constructions. Supporting braces of farms of coverage: on the norms of the Russian Federation, on the first maximum state percent of the use – 999 %; there is a percent of the use on the second maximum state – 999 %; on the norms of the Russian Federation taking into account loadings of supplier, on the first maximum state percent of the use – 999 %; there is a percent of the use on the second maximum state – 999 %; Stretched braces of farms of coverage: on the norms of the Russian Federation, on the first maximum state percent of the use – 64,2%; there is a percent of the use on the second maximum state – 721,8 %; on the norms of the Russian Federation taking into account loadings of supplier, on the first maximum state percent of the use – 25,8 %; there is a percent of the use on the second maximum state – 721,8%. Analysis presented allows establishing that at the load of supporting, stretched and central braces of farms of coverage of hothouses, by combinations of loadings characteristic for the place of location of hothouse of type of 6d, their bearing strength, and buildings can not be provided in general
