ABOUT THE NEW PARADIGM OF MATHEMATICAL METHODS OF RESEARCH
01.00.00 Physical-mathematical sciences
DescriptionIn 2011 – 2015, the scientific community was represented by a new paradigm of mathematical methods of research in the field of organizational and economic modeling, econometrics and statistics. There was a talk about a new paradigm of applied statistics, mathematical statistics, mathematical methods of economics, the analysis of statistical and expert data in problems of economics and management. We consider it necessary to develop organizational and economic support for solving specific application area, such as the space industry, start with a new paradigm of mathematical methods. The same requirements apply to the teaching of the respective disciplines. In the development of curricula and working programs, we must be based on a new paradigm of mathematical methods of research. In this study, we present the basic information about a new paradigm of mathematical methods of research. We start with a brief formulation of a new paradigm. The presentation in this article focuses primarily on the scientific field of "Mathematical and instrumental methods of economy", including organizational and economic and economic-mathematical modeling, econometrics and statistics, and decision theory, systems analysis, cybernetics, operations research. We discuss the basic concepts. We talk about the development of a new paradigm. We carry out a detailed comparison of the old and the new paradigms of mathematical methods of research. We give information about the educational literature, prepared in accordance with the new paradigm of mathematical methods of researches

NONPARAMETRIC KERNEL ESTIMATORS OF PROBABILITY DENSITY IN THE DISCRETE SPACES
01.00.00 Physical-mathematical sciences
DescriptionSome estimators of the probability density function in spaces of arbitrary nature are used for various tasks in statistics of non-numerical data. Systematic exposition of the theory of such estimators has been started in our articles [3, 4]. This article is a direct continuation of these works [3, 4]. We will regularly use references to conditions and theorems of the articles [3, 4], in which introduced several types of nonparametric estimators of the probability density. We have studied linear estimators. In this article, we consider particular cases - kernel density estimates in discrete spaces. When estimating the density of the one-dimensional random variable, kernel estimators become the Parzen-Rosenblatt estimators. Under different conditions, we prove the consistency and asymptotic normality of kernel density estimators. We have introduced the concept of "preferred rate differences" and are studied nuclear density estimators based on it. We have introduced and studied natural affinity measures which are used in the analysis of the asymptotic behavior of kernel density estimators. Kernel density estimates are considered for sequences of spaces with measures. We give the conditions under which the difference between the densities of probability distributions and of the mathematical expectations of their nuclear estimates uniformly tends to 0. Is established the uniform convergence of the variances. We find the conditions on the kernel functions, in which take place these theorems about uniform convergence. As examples, there are considered the spaces of fuzzy subsets of finite sets and the spaces of all subsets of finite sets. We give the condition to support the use of kernel density estimation in finite spaces. We discuss the counterexample of space of rankings in which the application of kernel density estimators can not be correct

Description
In this scientific article, the author deals with the application of specialized knowledge are competent persons (experts, specialists, forensic specialists) in modern law enforcement in various forms: procedural and non-procedural. The development of various information technology, hardware and collecting evidentiary information devices, as well as their application in day-to-day activities of bodies of inquiry (investigation) and operational units are by far enough effective activity. In this connection, there was a need for amending and supplementing the existing legislation the Russian Interior Ministry, some ordering process handling documents in the preliminary investigation as a whole. The author indicates the responsibilities of forensic units of internal affairs bodies as in the conduct of investigative actions and operational-search activity. At the end of the article, the author proposes an electronic form of the certificate of the expert forensic investigation in which are reflected issues of application of technical means in the course of the investigation, the rights and duties, as well as the responsibility of the forensic specialists, which provides a modern criminal procedure and criminal legislation of the Russian Federation, however, it has not so far reflected in existing regulations Ministry of Internal Affairs of Russia

Description
One of the actual directions of studying the history in modern world is the history of day-to-day life. Studying the industrial day-to-day life of builders on shock Komsomol building let us analyze their problems and the ways to solve them. The author gives the economic and political pre-conditions of organizing the patronage under the building of industrial objects on the South Ural. The concept “shock Komsomol building” and the classification of buildings are given. The main objects of Komsomol patronage which were situated on the territory of Orenburg area at that time are enumerated. The problems of women working at the building are viewed on the materials of Orenburg area. On the basis of archives the per cent ratio of youth and women working on the building is given. The industrial facts influencing on their socialization are examined. The main attention is given to the characteristics of industry, providing the builders with sanitary and domestic conditions of the objects and uniforms. The important aspect was also maintenance of safety measures on the building. The hard work of women who did not have the building education is stressed. The main spheres of professional employment of women on the building are enumerated

THE SHORTAGE OF WINTER WHEAT GRAIN CAUSED by P. triticina
06.00.00 Agricultural sciences
DescriptionThe article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots

DescriptionAdequate and effective assessment of the efficiency, effectiveness and the quality of scientific activities of specific scientists and research teams is crucial for any information society and a society based on knowledge. The solution to this problem is the subject of scientometrics and its purpose. The current stage of development scientometrics differs greatly from his previous appearance in the open as well as paid on-line access to huge amount of detailed data on a large number of indicators on individual authors and on scientific organizations and universities. The world has well-known bibliographic databases: Web of Science, Scopus, Astrophysics Data System, PubMed, MathSciNet, zbMATH, Chemical Abstracts, Springer, Agris, or GeoRef. In Russia, it is primarily the Russian scientific citing index (RSCI). RSCI is a national information-analytical system, accumulating more than 9 million publications of Russian scientists, as well as the information about citation of these publications from more than 6,000 Russian journals. There is too much information; it is so-called "Big data". But the problem is how to make sense of these large data, more precisely, to identify the meaning of scientometric indicators) and thus to convert them into great information ("great information"), and then apply this information to achieve the objective of scientometrics, i.e. to transform it into a lot of knowledge ("great knowledge") about the specific scientists and research teams. The solution to this problem is creating a "Scientific smart metering system" based on the use of the automated system-cognitive analysis and its software tools – an intellectual system called "Eidos". The article provides a numerical example of the creation and application of Scientometric intelligent measurement system based on a small amount of real scientific data that are publicly available using free on-line access to the RSCI

MILK PRODUCING ABILITY OF HOLSTEIN COWS OF VARIOUS ECO-GENETIC TYPES
06.00.00 Agricultural sciences
DescriptionThe article presents the comparative assessment of economic traits of Holstein cows of various ecogenetic types in the Volgograd region, the Russian Federation. The study of adaptive ability of Holstein cattle imported from the United States (245 heads), Denmark (245 heads), Germany (386 heads), and Australia (250 heads) has been carried out based on breeding plant OOO "Donskoye" in Russia since 2006. The milk producing ability of the animals was studied during the period of first three lactations. The cows imported from the United States showed the maximum productivity. The cows from the USA and Germany were registered to have the highest fat content in milk. The mathematical modeling for predicting production processes revealed that with respect to the milk yield, the Holsteins of Danish selection were superior to the cows of American, German, and Australian selections by the fifth lactation. The high correlation between the milk yield and the body weight, as well as between the body weight and the fat content of milk from Holstein cows of various selections has been established. The cows of Danish, German, and Australian selections showed a positive correlation between economic traits and genetic parameters for the period of three lactations. The cows from Australia have been proved to have higher indices of protein composition of milk (the total nitrogen content, the amount of essential amino acids). The level of the adaptive ability of the animals of the same breed but different eco-genetic types has been found to be stable

MODELING DEEP BAR INDUCTION MOTORS FOR SUGAR FACTORY ELECTRICAL POWER SUPPLY SYSTEMS
DescriptionThe article is devoted to solving the urgent task, which is improving the accuracy of transient simulation modes of power supply systems of sugar factories. The material of the article is exploratory in nature, manifested in the fact that we have studied various mathematical models designed for the analysis of symmetric modes of deep bar induction motors. A number of the provisions of article have scientific novelty, which lies in the approach to the choice of the coordinate system for modeling deep bar induction motors. We have formulated the requirements for transient analysis method for deep bar induction motor. We have developed the mathematical models of high-voltage induction motors in different coordinate systems for the analysis of steady-state and transient modes of operation. Based on double-circuit rotor model of induction motor, an analytical expression for the frequency characteristic of the deep bar induction motor is obtained. As an example, we have calculated and presented real and imaginary parts of the frequency characteristic of the induction motor type 2АЗМ-2000 with slip s = 1. The mathematical models of induction motors allow using mathematical apparatus more efficiently to explore different symmetrical modes of engines. The study proposed to use transients in the power supply systems of sugar factories for the analysis. The authors suggest an approach to modeling, which can also be useful for modeling induction generators
