CURRENT STATUS OF NONPARAMETRIC STATISTICS
01.00.00 Physical-mathematical sciences
DescriptionNonparametric statistics is one of the five points of growth of applied mathematical statistics. Despite the large number of publications on specific issues of nonparametric statistics, the internal structure of this research direction has remained undeveloped. The purpose of this article is to consider its division into regions based on the existing practice of scientific activity determination of nonparametric statistics and classify investigations on nonparametric statistical methods. Nonparametric statistics allows to make statistical inference, in particular, to estimate the characteristics of the distribution and testing statistical hypotheses without, as a rule, weakly proven assumptions about the distribution function of samples included in a particular parametric family. For example, the widespread belief that the statistical data are often have the normal distribution. Meanwhile, analysis of results of observations, in particular, measurement errors, always leads to the same conclusion - in most cases the actual distribution significantly different from normal. Uncritical use of the hypothesis of normality often leads to significant errors, in areas such as rejection of outlying observation results (emissions), the statistical quality control, and in other cases. Therefore, it is advisable to use nonparametric methods, in which the distribution functions of the results of observations are imposed only weak requirements. It is usually assumed only their continuity. On the basis of generalization of numerous studies it can be stated that to date, using nonparametric methods can solve almost the same number of tasks that previously used parametric methods. Certain statements in the literature are incorrect that nonparametric methods have less power, or require larger sample sizes than parametric methods. Note that in the nonparametric statistics, as in mathematical statistics in general, there remain a number of unresolved problems

THE SYSTEM OF HIGH SCHOOL IN THE GLOBALIZED WORLD
DescriptionThe article analyses the problems of science development and modernization of higher education. The role of higher school is under consideration which includes our success or failure both at production site and in the areas of science, techniques, technology, innovations, culture with regard to institutionalization of the world informational space and globalization of the world economy. In contemporary conditions, the higher education as a main component of the national educational complex is one of the most extensive and important areas of human activity which has integrated with all other areas of social life. The higher education is the largest sector of the Russian economy which, on the one hand, promotes the formation and development of the main productive force – the man and, on the other hand, - serves as an important source of mindset and methodology formation, an indicator of development of the socio-cultural environment of modern society. It also needs consideration that the expenses on the higher school at their socio-economical content are the investments in rising of the scientific and educational, the scientific and production potentials which result in increasing of the commonly shared human capital of the country

THE ROLE OF AGRICULTURE IN THE KUBAN REGION IN ENSURING FOOD SECURITY OF THE REGION AND THE COUNTRY
DescriptionThe article considers the issues of economic security of the country and argues that the priorities of economic security of the state vary depending on the historical period of development of the state, and under the influence of changes in the world. In modern terms they are monetary, energy and food security. The article is devoted to the issue of food security as an integral and essential part of national security, because the share of imports in total food variously estimated at from 30 to 50 %. Ensuring food security contributes to sustainable social climate in society. Russia, having all the main types of resources - land, water, energy, raw materials and labour, is not yet able to make full use of their populations wholesome food through own production. Needs completed large-scale imports even for those that it can produce sufficient not only for domestic consumption but also for export to the world market. Food security regions and the country serves as a basic indicator of human activity, and security is a priority of the state agrarian policy of the state.. The article proves that food security as an important element of national security involves ensuring the normal operation of such a complex biological system, as a people, mostly at the expense of domestic food production with the accounting standards recommended by the Institute of nutrition of the Academy of medical Sciences. The article is exploratory in nature, reflected in the fact that it dealt with issues of food security of the region and the country. The article is devoted to solving actual tasks associated with the role of agriculture in the Kuban in ensuring food security in the region and the country. In article on the basis of the analysis of the economic potential of Krasnodar region, in particular the agro-industrial complex of the region as the largest Russian producer and supplier of agricultural products and raw materials, justifies the role of agrarian and industrial complex of Krasnodar region and its ability to ensure food and economic security, and the country as a whole. The article discusses the direction for the effective management of food security of the country and its regions

01.00.00 Physical-mathematical sciences
DescriptionThe 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)

TECHNOLOGY FOR THE PREPARATION OF LIVESTOCK WASTEWATER FOR IRRIGATION OF AGRICULTURAL CROPS
DescriptionIn the article the authors propose various techniques for the preparation of livestock waste for agricultural use, particularly for irrigation. We have considered resource-saving environmentally safe technology for processing livestock waste pig farms based on the use of the reagent preparation phosphogypsum – residuals of phosphoric acid and fertilizers. The technology was tested and endorsed at the operating company LLC "Aksai field" of the Rostov region. Also based on this technology, we have offered the following technical solution: livestock wastewater is exposed to the vortex field with movable ferromagnetic particles, which contributes to more complete disinfecting effect. Further improvement of the technological scheme of training for livestock waste allowed to get more modern technical solution, including sewage treatment acidifying reagent is a suspension of phosphogypsum and slightly basic by oxychloride brand Aqua-Aurat. With the aim of reducing the cost and simplifying the technology of training we offered using a reagent, obtained from natural raw materials - silica-coagulant on the basis of nepheline instead of the low-base oxychloride brand Aqua-AuraTM. Aluminosilicate coagulant on the basis of nepheline may be used at high values of COD up to 2000 mg O/l and TBOD to 1500 mg O/l, which is a limitation for the use of such coagulants in the preparation of livestock wastewater pig farms. All the proposed technologies are based on the positions of resource and energy efficiency and environmental safety

THE REALNESS OF THE CRISES FORECASTING AND THE EFFECTIVENESS OF THE PREVENTIVE MEASURES
DescriptionIn the article we bring to light the delusions of the theory of the crises analysis as effectless at the creation of modern systems of the state anti-recessionary regulation. The principal problem is the variability definition of the term of crisis and the vagueness of the date of its start and the ending. The knowledge propagation in the field of the circular economy development is focused in Russia on the N. D. Kondratiev’s works in this area, repressed in the Stalin times. The attention is drawn to the fact that N. D. Kondratyev emphasized that, first, his cyclicity «lacks the preciseness and, of course, admits the exceptions, and secondly, it does not contain the author's explanation of the reasons, and, thirdly, the author saw that the upward waves were accompanied by the major social upheavals and the socials upheavals (revolutions, wars) in comparison of the periods of the downside waves. These circumstances are not taken into the consideration when creating «Kondratiev waves» in the excess long-term (up to 2060 year). The analysis of the development of the scope of anti-recessionary regulation in the operating regulatory legal base of the Russian Federation is performed. The author found that in the Russian legislation there are differs «the large-scale financial and economic crisis», «the crisis phenomena», «the systemic political and socio-economic crisis», «the government crisis», «the budget crisis» and many other types of the crises in the modern Russian economy

REACTION OF APPLE-TREE VARIETIES AND STOCKS ON CHANGE OF pH OF SOIL
DescriptionThe researches are devoted to the determination of physiological parameters of grafted apple-trees joining with the level of their resistance to the change of soil рН. The experiments were carried out in the conditions of lysimetric experience with the soils use characterizing by different value of рН. The scheme of experience included the following variants of soil medium reaction: neutral (рН 7,3), typical for black soils of plain part of the region (control); weak-acid (рН 6,2) existing in soils of foothill zone of the region (grey and brown forest); strong-acid (5.1) typical for brown forest soils; weak-alkaline(рН 8.3) occurring in black soils of south and sod-carbonate soils, strong-alkaline ( рН 8.8) typical for maternal types of many black soils. There were studied the varieties of apple-trees Prima, Florina and Renet Simirenko grafted on stocks M9 and MM106 and as well as corresponding the non-grafted stocks. The reaction of grafted apple-trees on change of рН of soil is specific and depends on adaptive possibilities of grafting components: varieties and stocks. At the stock M9 we can see the active growth of shoots and roots in the meaning of pH values from 5,1 (strong-acid reaction) to 7,3 (neutral). Plants MM106 prefer neutral (pH 7,3) and weak-alkaline (pH 8,3) soils. Independently from stocks for the variety Florina the most favorable weak-acid soils and the variety Prima – mainly neutral. The variety Renet Simirenko possesses enough high and stable functional activity in the conditions of wide range of the medium reaction: from very acid to alkaline one
