THE CONCEPT OF UNINTERRUPTED POWER SUPPLY SYSTEMS
DescriptionWe have revealed the main reasons for interruptions in power supply to consumers of electricity. To improve the reliability and the efficiency of power supply for responsible consumers, we have proposed to develop energy efficient combined energy-saving systems for uninterrupted power supply with use of renewable energy sources. The article lists major principles of the development of such systems; it shows the necessity of constructing a generalized schema that contains the possible types and the sources of electric power converters. It also reveals the modern requirements to systems of uninterrupted energy supply. To improve the operational and technical characteristics of the uninterruptible power supply, it has been proposed to use a new circuitry that includes a contactless power generators, the direct frequency converters used to stabilize the voltage and frequency of the current generators of wind turbines, static converters made with the use of single-phase transformers with rotating magnetic field, universal static converters that can operate in the regimes of known types of converters. The article presents features of the modular construction of systems of uninterrupted energy supply and optimization of their structural decisions on key performance criteria. It shows the algorithm of synthesis of structural designs of combined systems of uninterrupted power supply. An important step for further research with the aim of improving operational and technical characteristics of the combination of uninterrupted power supply systems is the mathematical modeling of physical processes in power circuits of the system in both normal and emergency modes of operation

Description
In this article, we examine questions about realization of interdisciplinary connections in the process of teaching of mathematics the students of economic specialties. Taking into account the circumstance that economic specialties are integrating information from mathematical, natural, humanitarian and socioeconomic disciplines, going near the selection of maintenance of course of mathematics must be oriented to the mathematical apparatus for all cycles forming certain abilities and skills. Thus, in the process of teaching mathematics we have to emphasize the necessity of maintenance of "vertical" connections in a course mathematics, marking that maintenance of flat rate of mathematics can not be certain from the cleanly pragmatic point of view, based only on the specific of future specialty of studying, without the account of internal logic of mathematics, id est., from a course mathematicians we must not eliminate questions and divisions, not having a direct professional orientation, but providing internal subject connections or the logic of the discipline. Accordance to the criterion of internal subject integrity means, that maintenance of the course of mathematics will not grow into totality of fragmentary information necessary for the special preparation, and will possess necessary plenitude, logical uncontradiction and sequence. On the other hand, it is necessary to accent attention on the study of the different processes and phenomena, lighted up in general professional disciplines, as studying of all these questions must be of the ponderable use in the professional becoming of future specialist, i.e. the special importance is acquired by interdisciplinary integration connections at the level of which the applied professional orientation of the studied material comes true

THE METHOD OF ENGINEERING CALCULATION OF DRIVE DEVICES FOR FORAGES PREPARATION
DescriptionThe article presents results of the study of devices for preparation of feed based on the relative helical drums. In addition, we have created a method of calculation of the drive, including motor power. We have given a calculation sheet for relative helical drums of types of 5.1 and 3.1, as well as typical schemes of devices for preparation of feed (feed-making machines) composed of hollow equilateral triangular of hollow tetrahedrons pyramids and hollow octahedra. The created method of calculation of the drive was tested in the calculation of power consumption of feed-making machines based on spiral reels of 5.1 type mounted using hollow tetrahedrons and spiral reels of 3.1 type, assembled from hollow octahedra. It is shown that in the calculation of the actuator, we should not only take into account the mass loading of feed components, the relative weight of the screw drum assembled with wheels, for a symmetrical load location, but also a lot of download components of feeds, arranged in a spiral relative the drum asymmetrically to the axis of rotation. Thus, summing up the power of the electric motor, required for relative rotation of the screw drum symmetrically loaded and also under asymmetric load we define the motor power for the device for preparation of feed, or feed-making machine

METHODS OF REDUCING SPACE DIMENSION OF STATISTICAL DATA
01.00.00 Physical-mathematical sciences
DescriptionOne of the "points of growth" of applied statistics is methods of reducing the dimension of statistical data. They are increasingly used in the analysis of data in specific applied research, such as sociology. We investigate the most promising methods to reduce the dimensionality. The principal components are one of the most commonly used methods to reduce the dimensionality. For visual analysis of data are often used the projections of original vectors on the plane of the first two principal components. Usually the data structure is clearly visible, highlighted compact clusters of objects and separately allocated vectors. The principal components are one method of factor analysis. The new idea of factor analysis in comparison with the method of principal components is that, based on loads, the factors breaks up into groups. In one group of factors, new factor is combined with a similar impact on the elements of the new basis. Then each group is recommended to leave one representative. Sometimes, instead of the choice of representative by calculation, a new factor that is central to the group in question. Reduced dimension occurs during the transition to the system factors, which are representatives of groups. Other factors are discarded. On the use of distance (proximity measures, indicators of differences) between features and extensive class are based methods of multidimensional scaling. The basic idea of this class of methods is to present each object as point of the geometric space (usually of dimension 1, 2, or 3) whose coordinates are the values of the hidden (latent) factors which combine to adequately describe the object. As an example of the application of probabilistic and statistical modeling and the results of statistics of non-numeric data, we justify the consistency of estimators of the dimension of the data in multidimensional scaling, which are proposed previously by Kruskal from heuristic considerations. We have considered a number of consistent estimations of dimension of models (in regression analysis and in theory of classification). We also give some information about the algorithms for reduce the dimensionality in the automated system-cognitive analysis

SIMULATION OF TURBULENT FLOW IN A CAVITY ON THE NAVIER-STOKES EQUATIONS
01.00.00 Physical-mathematical sciences
DescriptionThe article deals with the numerical solution of the Navier-Stokes equations describing turbulent flow in a rectangle cavity or in a cuboid with one open face at high Reynolds numbers. It is known, that there is a mechanism of turbulent mixing in natural systems, leading to an increase in the viscosity of the continuous medium. In this regard, we suggest methods of regularization of the Navier-Stokes equations, similar to the natural mechanisms of mixing. We proposed the models based on the properties of the turbulent environment. For this we modified the continuity equation taking into account the pressure fluctuations. It is shown that the incompressibility condition is can be violated due to pressure fluctuation even for flows with low Mach numbers. Modification of continuity equation by the introduction of turbulent viscosity allows the regularization of the Navier-Stokes equations to solve the problems with rapidly changing dynamic parameters. It was shown that the modification of the continuity equation taking into account turbulent fluctuations leads to a system of nonlinear equations of parabolic type. A numerical model of turbulent flow in the cavity with the rapid change in the parameters of the main flow developed. Discovered type of instability of the turbulent flow associated with the rapid changes in the main flow velocity. In numerical simulations found that due to the acceleration of the main flow there is the unsteady vortex flow in the cavity, which is characterized by the integral of energy not vanishing with time, vibrations that have a certain period, depending on the turbulent viscosity

THE NECESSITY OF IMPROVING THE SYSTEM OF DEVELOPMENT OF REGULATION OF SMALL AGRARIAN BUSINESS
DescriptionPractice shows that the level of development of small agricultural farms is an important indicator of favorability of the conditions created by government for development of production and rural territories. Conversely, the degree of development of rural areas has an impact on the development of small agricultural entities. It is necessary to increase the independence, motivation, municipal authorities in socioeconomic development of given territories. However, today, there is a relative decrease in the level of support for small businesses. Since 2007, the Support of agriculture in our region has grown almost by three times, but small agrarian business grew only by 34.3%, that is, in fact, observed as a negative trend, when adjusted for inflation. Without a system of state support of small business it is problematic to conduct a correct reproduction of the herd and to increase the volume of industry’s output. Such situation results in: lower rural incomes, especially in private subsidiary farms; the number of jobs, increase of unemployment, social tension in society, and a negative effect on the regional economy. It is necessary to improve the economic mechanism of state support of small businesses, to improve the conditions of lending and investments, to create conditions for increasing production of marketable products and new jobs, to increase rural employment, to improve the system of cooperation in production, processing, storage, transportation and sale of products to small businesses, to improve social infrastructure, to improve the quality of rural life. The authors have developed and offered corrective suggestions for implementation of the regional target program of development of small forms of businesses for 2016- 2020 with the definition of deadlines and funding, by blocks of the organization of competitive production, support for family farms, system of agricultural cooperation, and marketing of commercial products
