Description
Agricultural producers interested in marketing of raw materials, whereas processing companies are interested in the establishment of raw material zones, providing capacity utilization; therefore, the establishment of sustainable linkages between producers and processors of raw materials is an objective necessity. In the article, with the help of mathematical methods we examine the conditions of mutually beneficial economic relations between agricultural producers and processing enterprises. Mathematical model for estimating the profits of the company is built of the following conditions: producers sell processing plants raw materials, determined by the coefficient of the interest in the partnership at an agreed purchase price, and the remaining raw materials are processed, so they can sell their products independently. Profit of the processing plant is determined by the mathematical model. To describe the nonlinear market-based sales of goods from its retail price we used a hyperbolic demand function

Description
This article presents main water supply systems and justifies the choice of direct flow of water supply system in the application of regulation of electric drive for pumps, which doesn’t have any tanks to create pressures required for fire-governmental purposes. This avoids interruption in the supply of reserve while water freezing. In the article the substantiation of the necessity of implementation of adaptive algorithm in modern-WIDE frequency converters by a substantiation of the number of stages of ratio control of voltage-frequency mains. It was revealed that the number of degrees of regulation of 10-12 gives optimum. Modern frequency converters allow you to change the regulation law, establishing 3-5 points of regulation. Therefore, the introduction of adaptive algorithm will reduce the power consumption of the electric drive of the pump of the water supply system. The article shows the simulation model of the "the converter frequency-induction motor," plots of the stator current of mains frequency and active power, surface speed and phase current when changing the voltage and frequency of the mains. These dependences confirm to have applicability of adaptive algorithm in the regulation of modern frequency converters with the skalar administration. Simulation model confirms the sub-physical experiments on a real motor and frequency converter with adaptive control algorithm. As a result of the selection of the parameters, we obtain the voltage reduction of the phase current, and reduce electricity consumption by 5-7%

THEORETICAL FOUNDATIONS OF FORMATION OF ENTREPRENEURIAL CLUSTER
DescriptionThis article investigates the development of entrepreneurial cluster set direction to support the creation of innovation clusters in Russia. In the face of increasing international competition, one of the most effective ways of development of small and medium-sized enterprises in the field of innovation is their clustering. We have discussed foreign experience of studying cluster initiatives and events on social development of the regions in the context of sociological knowledge about clusters. We have revealed the meaning of an innovation cluster and the difference between business and innovation clusters. The analysis has shown that a key advantage of the business cluster in relation to the network is the participation of state authorities, as well as functional and territorial factor. On the basis of the author's research we have highlighted a number of problems which solution has been carried out through the creation of business clusters

Description
At present, the cultivation of agricultural products is on a level where the growth of productivity and quality is only possible by using the latest achievements of science. Scientists have been developing elements of agro-technologies of complex applications of growth regulators, fungicides and fertilizers in growing winter wheat, providing a significant increase in productivity and quality of agricultural products, reduction of labor costs, energy and all kinds of resources, sustainable harvesting, even in the zone of risky agriculture. Plant growth regulators have multifunctional properties, which are expressed in the regulation of plant growth and development, and in increasing their resilience to adverse weather conditions and many diseases. However, despite the fact that there are many examples of extremely high economic efficiency of plant growth regulators, in terms of production and use of pesticides are much inferior. Retardants and defoliants are used more widely. However, low rates of regulators and elicitors, the ability to manage with their help the growth and development of plants; change the resistance of plants to various external factors determines their prospects. We propose to apply the "agrochemical cocktails." It will induce the systemic plant resistance to the whole growing season, which is not possible in the case of using only one of the fungicides and bactericides. It is necessary to take into account the features of the functioning of the immune system of plants and to develop technological methods of influence on the key stages of the immune response of plants

THE APPROACHES TO UNDERSTANDING THE SIGNIFICANCE OF ELITISM ARCHETYPE AS THE BASEMENT OF POLITOLOGY
DescriptionStudying the archetype of elitism is extremely important to correctly assess the direction of historical development of the state. This provides the possibility for reasonable buildup of the state domestic and foreign policy and presents the base for constructive development of the methodology of scientific cognition in the field of politology, philosophy and history. However, as the human is a complex biological system, many aspects of the human social activities are based on and conditioned by genetic potential of the human. The study provides definition of the elite and elite communities. It sais that the whole course of the history is eventually a positive or a negative interaction of elites. Nevertheless, the appearance and functioning of any elite is only possible and understandable in the context of some particular civilization, country or in a specific period of time. If the elites are taken out of the historical context, they get a nonmaterial and mythical status. If the archetype of elitism already moving along the time axis for many hundreds and even thousands of years is present, now we can observe the qualitative change of the contemporary elite along with the change of its functions and its purpose itself. On the one hand, we can observe the process of old elites degeneration; on the other hand – new elite formations keep to appear which can be essentially different from their antecedents and have other functions and purpose

MODELING THE DYNAMICS OF THE MARKET SYSTEM
DescriptionIn the modern conditions of dynamic development of the market system, the economy, feeling polynomial enthusiasm and recessions, demands external influence, regulation, management. It isn't possible to realize an effective control system of economy without understanding of a consequence. The regulating structure represented by the state needs an effective system of the support of decision-making allowing to estimate the consequences of the made decisions before their direct realization. Use of modern methods of complex estimation for modeling of market system on the basis of trees of criteria and matrixes of convolution allows forming a static market model in the form of the functions of sensitivity interpreted as curves of supply and demand. However, the questions of creation of dynamic market system on the basis of these mechanisms weren't discussed so far. In this article the questions of possibility of modeling of dynamics of the market system built on the basis of mechanisms of complex estimation are discussed. Relevance of the chosen method depends on the possibility of preliminary formation of possible outcomes of an event in the form of the count on definition further of probability of transition to each of states on the basis of a complex assessment of the individual of "advantage" of such transition. An additional benefit of such approach is that fact that when forming market system from some contingent of participants with different behavior models for each of them there is an opportunity to create the scenario, and when receiving at a stage of modeling of result to reconsider the new created structure of structure of society

VOLTAGE REGULATORS OF SYNCHRONOUS GENERATORS
DescriptionSynchronous generators are the primary source of electrical power autonomous electrosupply systems, including backup systems. They are also used in a structure of rotating electricity converters and are widely used in renewable energy as part of wind power plants of small, mini and micro hydroelectric plants. Increasing the speed and the accuracy of the system of the voltage regulation of synchronous generators is possible due to the development of combined systems containing more stabilizers. The article illustrates the functional schemes of circuit voltage stabilizers and frequency synchronous generators (with electromagnetic excitation and permanent magnet excitation) and describes the features of their work, including two and three-aggregate rotating converters of electricity used in uninterruptible power supply systems. To improve the technical characteristics of the system of stabilization we have proposed functional solutions for stabilizers of synchronous generators made on the base of direct frequency converters and using a transformer with a rotating magnetic field. To improve the reliability of and to improve the operational characteristics of the autonomous independent sources of electricity we suggest creating the main functional blocks and the elements of the stabilization system in a modular way. The functional circuit solutions of voltage regulators of synchronous generators and the characteristics of their work considered in the article, are able to improve the efficiency of pre-design work in the development of new technical solutions for stabilizing the voltage and the frequency in synchronous generators of electrosupply autonomous systems
