THE RATIONALE FOR SELECTING THE METHOD OF FORECASTING THE DEVELOPMENT OF A DIVERSIFIED CORPORATION
DescriptionApplication of classical forecasting methods applied to a diversified corporation faces some certain difficulties, due to its economic nature. Unlike other businesses, diversified corporations are characterized by multidimensional arrays of data with a high degree of distortion and fragmentation of the information due to the cumulative effect of the incompleteness and distortion of accounting information from its enterprises. Under these conditions, the applied methods and tools must have high resolution and to work effectively with large databases with incomplete information, to ensure correct common comparable quantitative processing of the heterogeneous nature of the factors measured in different units. It is therefore necessary to select or develop some methods that can work with poorly formalized complex tasks. This fact substantiates the relevance of the problem of developing models, methods and tools for solving the problem of forecasting the development of diversified corporations. This article compares methods of forecasting and encourages using the ask analysis which has a good theoretical justification for the meaningful interpretation of a knowledge model based on information theory; high accuracy and independence of calculation results of the unit of measurement baseline data through the use of not the correlation matrix, as in statistical systems, and matrices of knowledge. A well-developed and available Toolkit of the ASK-analysis which is an intellectual system called "Eidos" (created by E. V. Lutsenko, 1994) allows, on the basis of fragmented, noisy source data of various nature (numeric, text) to create models of large dimension. The ASK-analysis and the system of "Eidos" have been widely and successfully used in economics, engineering, agriculture, sociology and other fields. These features of the ASK-analysis have led to the fact that it was chosen as the method of forecasting of dynamics of indicators of the corporation

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

PHYSICAL MODELING OF ODOMETRIC COMPRESSION OF SAND
DescriptionThe odometric compression of sand with constant rate of loading (CRL) or constant rate of deformation (CRD) and continuous registration of the corresponding reaction allows to identify the effect of stepwise changes of deformation (at the CRL) and the power reaction (at the CRD). Physical modeling of compression on the sandy model showed the same effect. The physical model was made of fine sand with marks, mimicking large inclusions. Compression of the soil at the CRD was uneven, stepwise, and the strain rate of the upper boundary of the sandy model changed cyclically. Maximum amplitudes of cycles passed through a maximum. Inside of the sand model, the uneven strain resulted in the mutual displacement of the adjacent parts located at the same depth. The growth of external pressure, the marks showed an increase or decrease in displacement and even move opposite to the direction of movement (settlement) the upper boundary of the model ‒ "floating" of marks. Marks, at different depths, got at the same time different movements, including mutually contradictory. The mark settlements sudden growth when the sufficiently large pressure. These increments in settlements remained until the end of loading decreasing with depth. They were a confirmation of the hypothesis about the total destruction of the soil sample at a pressure of "structural strength". The hypothesis of the "floating" reason based on the obvious assumption that the marks are moved together with the surrounding sand. The explanation of the effect of "floating" is supported by the fact that the value of "floating" the more, the greater the depth

Description
The concept of the research is to justify the necessity to develop the regulatory declared dispositive basis in the system of social, ecological and economic management of the urbanized areas within the environmental system of the region, through the improvement of organizational-economic management mechanism of region natural resources and understanding the tools of this mechanism. The administrative-territorial formations are specific due to the necessity of being them considered in terms of socio-economic development as well as in the context of ecological and economic development of the territory that is connected with the necessity to ensure its sustainable socio-economic development. Ecological and economic management of cities and other urbanized areas are of the entire spectrum of public relations in the sphere of natural resources use and protection. The study of the city as the ecological and economic system is based on a number of conceptual problems in the applied management methods that ignore the general specificity of cities as the urban areas and sites of ecological - economic management, regardless of their level - single-industry towns, big cities or cities of regional importance. The ongoing soil degradation can affect the living conditions of future generations. The soil damage is caused mainly by industrial enterprises, being in various forms of ownership nowadays, including private. The improvement of legislation on soil protection from industrial pollution is a very relevant issue

ANALYTICAL TOOLS OF VECTOR RISK ASSESSMENT OF THE FINANCIAL MARKET
DescriptionIn rapidly changing conditions of the modern world, analysts and decision makers are in need to use new formal means of analysis and evaluation of alternatives problems. This work is dedicated to the development of such tools. The article presents a detailed analysis and technical and economic characteristics of the subject area - the financial market and its specific components - the value of a time series of gold, silver, palladium, platinum, and two kinds of exchange rates: EUR / RUB, USD / RUB. The authors have proposed a 5-criteria economic-mathematical model of the main components of the ranking of the financial market. The authors argue the impossibility of using a single integrated set of criteria for the replacement of the criteria or the use of criteria convolution procedures as the standard procedure of solving the problem of multi-criteria optimization. It demonstrates that such criteria as criteria for "risk" must be considered as an estimate of the degree of deviation from the expected value of the possible values of this criterion. The practical significance of the results is determined by the fact that the main points, conclusions, recommendations, models and methods can be used in order to improve the management and planning of development strategies of banking systems, trading platforms, as well as by developers of information and analytical systems to support management decisionmaking

RESTRICTED MANY-BODY PROBLEM IN THE RICCI FLOWS IN GENERAL RELATIVITY
01.00.00 Physical-mathematical sciences
DescriptionIn this article, the restricted problem of three and more bodies in the Ricci flow in the general theory of relativity considered. A system of non-linear parabolic equations describing the evolution of the axially symmetric metrics in the Ricci flow proposed. A model describing the motion of particles in the Ricci flow derived. It is shown that the theory describing the Ricci flow in the many-body problem is consistent with the Einstein-Infeld theory, which describes the dynamics of the material particles provided by the singularities of the gravitational field. As an example, consider the metric having axial symmetry and contains two singularities simulating particles of finite mass. It is shown that the static metric with two singularities corresponds to Newton's theory of the two centers of gravity, moving around the center of mass in circular orbits in a noninertial frame of reference, rotating with a period of bodies. We consider the statement of the problem of many bodies distributed at the initial time on the axis of symmetry of the system. In numerical calculations, we studied the properties of the gravitational potential in the problem of establishing a static condition in which multiple singularities retain the initial position on the axis of the system. This is achieved due to relativistic effects, which have no analogues in Newton's theory of gravitation. Using the properties of relativistic potentials we have justified transition from the relativistic motion of the particles to the dynamic equations in the classic theory

DescriptionThe provisions to improve the efficiency of vineyards are the selection of varieties different by ripening, adapted to local conditions, as well as the use of a new generation of fertilizers. According to phenological observations and actual production period, the varieties of table grapes are divided into groups by ripeness – early and middle. According to the yield, there were emphasized the following varieties: in the early group – Cardinal (11,3 t/ha), Vostorg (Delight) (11,2 t/ha), Bogatyrskiy (10,9 t/ha); in the middle ripening group - Kishmish luchistyj (11,2 t/ha), Moldova (11,2 t/ha), with large clusters (266-453 g) and berries (3,2-7,0 g), a berries’ crush resistance was from average 850 g to high up to 1528 g, berries’ strength of attachment to fruitstems was high – 259 and solid – 666 g. It was observed the positive benefit of foliar application of a new generation of micro fertilizers. In the phase of ripening of berries the total length of shoots of fertilized variants was above the control variant for the variety Ranniy Magaracha on 2,6-13,4%, for the Karaburnu on 2,5-13,9%. Maturing shoots in this phase was on the variety Ranniy Magaracha – 76,5- 92,4% (control variant – 74,6%), while on the Karaburnu variety – 72,8-83,1% (control variant – 70,9%). Fertilizers contributed to the increase of leaf area on the Ranniy Magaracha variety on 3,9-15,9 thousand sq.m/ha (control variant – 20,0 thousand sq.m/ha), on the variety Karaburnu on 3,4-13,1 thousand sq.m/ha (control variant – 22,8 thousand sq.m/ha). The yielding capacity on the fertilized variants have increased by 7,1-23,0% depending on the variety. The maximum yielding capacity was obtained when using compound nanotechnological fertilizer Nagro on the variety Ranniy Magaracha – 13,4 t/ha and on the variety Karaburnu – 15,5 t/ha
