01.00.00 Physical-mathematical sciences
Description
The article presents a theoretical substantiation, methods of numerical calculations and software implementation of the decision of problems of statistics, in particular the study of statistical distributions, methods of information theory. On the basis of empirical data by calculation we have determined the number of observations used for the analysis of statistical distributions. The proposed method of calculating the amount of information is not based on assumptions about the independence of observations and the normal distribution, i.e., is non-parametric and ensures the correct modeling of nonlinear systems, and also allows comparable to process heterogeneous (measured in scales of different types) data numeric and non-numeric nature that are measured in different units. Thus, ASC-analysis and "Eidos" system is a modern innovation (ready for implementation) technology solving problems of statistical methods of information theory. This article can be used as a description of the laboratory work in the disciplines of: intelligent systems; knowledge engineering and intelligent systems; intelligent technologies and knowledge representation; knowledge representation in intelligent systems; foundations of intelligent systems; introduction to neuromaturation and methods neural networks; fundamentals of artificial intelligence; intelligent technologies in science and education; knowledge management; automated system-cognitive analysis and "Eidos" intelligent system which the author is developing currently, but also in other disciplines associated with the transformation of data into information, and its transformation into knowledge and application of this knowledge to solve problems of identification, forecasting, decision making and research of the simulated subject area (which is virtually all subjects in all fields of science)

ANALYSIS OF BUSINESS RISKS BASED ON A LIMITED RANGE OF CRITERIA
Description
Business risk is an integral part of the economic activities of any organization. Currently, compulsory and one of the main criteria of normal and stable operation of the economic entity is timely risk assessment of entrepreneurial activity in order to prevent further negative consequences. Issues of economic risk analysis of business are becoming more relevant, especially in the context of the global financial crisis. This article discusses the methods of analysis of business risks on the basis of a limited range of criteria. Studies have shown the example of a particular Agriculture Organization. We consider the evaluation of the structure of the balance sheet and analysis system by W. Beaver, evaluation according to the method of calculating the financial condition of agricultural producers. On the example of the organization under study we have given an assessment of business risks with the use of a limited range of criteria. In the context of each block there are specific indicators characterizing the increase or decrease the risks of entrepreneurship. Figures for the study were analyzed for the organization, and compared to the theoretical value is sufficient. For each of the aspects of the assessment of business risks on the basis of a limited range of criteria there are valid conclusions. Based on the study, we have stated the advantages and disadvantages of the test approach to risk assessment of entrepreneurial activity of the economic entity

Description
The problem of environmental contamination by heavy metals is significant problem of urbanization. The search of ways of indication heavy metals pollution becomes actual, because of their simplicity and affordability. A widely used test objects for heavy metals pollution indicators are leafy mosses used for bioindication, because they are highly sensitive to any stress factor. The research shows that bioindication with using leafy mosses as test objects is highly effective method definition of heavy metals pollution. Using of bioindication methods are promising techniques for the assessment of the contamination of ecosystems by heavy metals. Through the use of this method, it is possible indication of pollution of the surface layer of air with heavy metals. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the heavy metals pollution biomonitoring of urbosystems. The accumulation features of heavy metals in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. pylaisiella moss (P. polyantha) accumulates the largest amounts of the following heavy metals: Zn, Cr, Pb, Sr, Ni (Kc to 1.07), and Cu. According to the Kc values, all the studied elements accumulated by pylaisiella moss form the following series of biological uptake: Zn > Pb > Sr > Cr > V > Ni > Cu > Cо. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of heavy metals pollution in different polluted zones

Description
The article discusses approaches to differentiation of agricultural enterprises of the Krasnodar region on the production potential. As the object of study we have selected 640 agricultural enterprises of the Krasnodar region for 2013. Cluster analysis allows visually differentiate organizations in economic parameters. The advantage of this approach is evident when analyzed a large number of organizations and performance. It is preferred that clustering is made using hierarchical cluster analysis and k-means. The results of clustering agribusiness enterprises of the Krasnodar region on the main economic indicators were given. During the analysis, we revealed that the AIC enterprises of the Krasnodar region generally form five clusters. Cluster 1 is characterized by a very high level of development of the productive capacity of agribusiness enterprises, consists of 12 organizations and is defined as "extra large" organization. 2nd cluster is characterized as "large", it includes 25 agricultural enterprises. 3rd and 4th clusters - as "average", they account for 60% of the acreage, 52.6% of fixed assets for agricultural purposes. 5th cluster is represented as "small", is a leader in the number of organizations - 371 units and contains a minimum number of employees - 30 people. It is assumed that these approaches can be used for analysis of agricultural organizations of the Krasnodar region with different levels of specialization and in other studies

APPLICATION OF ELECTRICAL TECHNOLOGIES FOR ENHANCING OF IN-HEAVE MICROCLIMATE
Description
One of the integrative indicators of over-all performance estimation is profitability of the production. It is possible to increase competitiveness of beekeeping production as well as national food security via implementation of efficient electrical technologies. Enhancing of microclimate parameters in hives allows us to enhance the intensity of spring development of bees. The counting of integrate heat losses in heaves with ozone treatment and without the one was carried out. Using the obtained results and graphs we can develop the automation system for in-heave microclimate control. The article presents the graphs of heat losses in a beehive on the outdoor temperature and relative humidity, which were obtained experimental. It is proved that when the outdoor temperature from -15 to 8 ° C and the change in ambient air humidity of 60 to 100% heat loss beehive decrease from 4-5 W to 0.2-0.4 W. It is concluded that treatment of bees by ozone, while reducing the concentration of pathogenic microorganisms, will reduce the energy loss by reducing the air exchange, i.e. improve conditions for the development of the bee colony

THE IMPACT OF THE SANCTIONS ON THE INVESTMENT CLIMATE AND INDUSTRIAL POLICY OF RUSSIA
Description
In this article considers the condition of investment climate in the industry and the prospects of its change from the result of imposing sanctions from the West. This article considers common economic indicators of the Russian domestic market and defines priorities of increasing investment attractiveness in industry, simultaneously brings out positive and negative sides. We have determined that dependence of Russian regions from economic sanctions is very ambiguous. We have predicted the possible situations where the industry can suffer certain decline and also represented the fields of Russian industrial production where the indicators may have positive results from sanctions. The article indicates a number of spheres of domestic production which directly depended from external impact of foreign countries. It emphasizes the fact that in the order to rise the capital and economic growth we should create the favorable qualitative investment climate and develop own production capacities on the basis of innovation and modernization. In this article we are taking into account the fact of growth of investment activity from the position of financing. Effective instruments for attracting investment are: the creation of special economic areas of advanced development, implementation of measures of reducing administrative barriers of business. Attractive investments will create the financial basis not only for import substitution, but for reindustrialization of the industry
