THE STUDY OF LEARNING ALGORITHMS OF NEURO-FUZZY SYSTEMS CONTROL OF BIOTECHNOLOGICAL PROCESS
DescriptionThe subject of study of this work was learning algorithm of neuro-fuzzy systems with different membership functions. In the prior works there are no published studies of such studies, making it difficult synthesis of neuro-fuzzy control system with new objects in the application of biotechnology, including technological agribusiness entities. A comparative analysis of learning algorithms of neuro-fuzzy system with different membership functions using the method of error back propagation and а hybrid method. For this we used a training sample that contains data of temperature and concentration of dissolved gas in the culture liquid: oxygen (pO2), carbon dioxide (pCO2) of a biotechnological process. It is shown that the hybrid method carries out training of a neural network for the number of periods is 23 times smaller than the algorithm back-propagation errors. The studies found that the two-sided Gaussian membership function provides the smallest learning error of the network δ equal of 3,28•10–3, compared to the other, giving the largest error of training the neural network δ=0,138. Therefore, the task of running the fermentation process effective is the use a hybrid method of education and two-sided Gaussian membership functions. According to the research, we can conclude that for the adaptation of neuro-fuzzy network ANFIS and fuzzy inference system Sugeno zero order to solve biotechnological process control tasks microbiological production efficiency is to use a hybrid method of education and bilateral Gaussian membership functions

COMPARATIVE ANALYSIS OF THE VENTILATION MODELS OF THE SUBSTRATE WHEN COMPOSTING
DescriptionIn the article we have performed a comparative analysis of a traditional system of air supply to the bioreactor during the composting process and the developed system with lateral air supply. We have proven to reduce temperature variation of the substrate as a result of the use of the ventilation system by 35%. During the simulation, equal to 1.0 hour, a ventilation system with side air flow provides a reduction of the accumulated degree of heterogeneity of status parameters of the substrate by 58%. Use of the ventilation system with side air flow reduces the duration of technological cycle of composting 7 %. This article was prepared in the framework of the scientific project 16-48-230441 a(R) "Mathematical modeling of the processes occurring in the automated installation for year-round production of organic fertilizers in the conditions of the Krasnodar region", financed by RFBR and administration of the Krasnodar region

Description
For different industries, there was a need of creation new equipment and mechanisms with enhanced characteristics. Special requirements are imposed to energetic and mass-dimensional indices of systems of electric drives as one of the main components of such devices. Mass-dimensional and energetic indices due to constructional features and the used management system will allow improving the use of special or controlled asynchronous cascade systems of an electric actuator of axial construction. One of the main difficulties is simulation and design of special systems of the electric drive. In the article, we offer a new approach to determination of magnetic model parameters of the stator of a component of a controlled asynchronous cascade electric actuator of axial construction

OPTIMIZATION OF THE ENERGY CHARACTERISTICS OF A CHILLER WITH COLD ACCUMULATOR IN TROPICAL CLIMATE
DescriptionThere is always an abrupt variable schedule of cooling consumption in processing enterprises with seasonal supply of raw materials. This causes peak heat load on the refrigeration unit. The introduction of cold accumulators (CA) in refrigeration units is one of the modern ways of reducing the cost of refrigeration. The use of cold accumulators allows you to smooth out uneven thermal load on refrigeration, reduce the cooling capacity of the installed equipment and technical equipment. The night season experiences minimum heat leakage and power consumption of frozen ice water (coolant or refrigerant) but the refrigeration capacity is used during the daytime at peak heat load of cold consumption at peak electricity consumption. The major cost of electricity to generate refrigeration to compensate for heat loss coincides with the period of high electricity tariffs as shown from the analysis of cold consumption. The development of refrigeration systems with cold accumulation in “night” period of low electricity tariffs is an important issue based on the forgoing

A DEVELOPMENT TRAP FOR CORPORATE CAPITAL
DescriptionThe article considers specific obstacles (traps) which can occur during the embedding of the corporate capital in a changeable economic system of Russia. The author reveals the causes and consequences of emergence traps in the development of corporate capital, among which are: the rapid transformation of the financial component of economic relations and prolonged elevation of power over the property, the unpredictability and variability of economic policy, institutional deformation, resulting in scarcity of necessary resources for the development of corporate capital and embedding it in the flow of change, lack of trust entities to the policies of the state, «manual economy». The aim of the study is an in-depth search of potential possibilities of corporate capital and the ways out of the formed on the system of socioeconomic transformations of the pitfalls of development. In the process of research, the author used the cognitive capabilities of the system approach, institutional theory, and the conceptual provisions of politico-economic and evolutionary theories. The study was conducted with the help of dialectical, empirical, historical, logical, structural methods

MODELING AND DIAGNOSIS OF TRAINING PRODUCTIVITY OF SCIENTIFICPEDAGOGICAL PERSONNEL
DescriptionThe article presents the criteria for the effectiveness of the scientific and pedagogical workers of higher skill levels for the preparation of scientific and pedagogical staff. It is known that the preparation of the teaching staff (PhDs) - one of the most important activities of higher education institutions; Moreover, when the state accreditation of higher education institutions compulsorily taken into account indicators that reflect the impact of training candidates. Also, of course, that the training of the teaching staff (PhDs) - activities that require both high levels of research and pedagogical competence. This means that the results of scientific and teaching staff higher qualification levels for the preparation of the scientific staff - both indicators of research and pedagogical competence; own training of researchers - an area of "crossing" of scientific and pedagogical activity. Unfortunately, the increase in the number of scientific personnel being prepared does not always mean quality growth. Often trained scientific personnel (PhD) not only do not approach the level of competence of its research (the results of research) to the supervisor, and stopped to engage in scientific activities after defending his doctoral dissertation (or engaged at a low level). Therefore, the article authors consider it expedient to propose indicators that reflect not only the amount and timeliness of the research training (PhD thesis defense sometimes occur many years after graduate school), but also the productivity of this activity. From the point of view of the authors, the success of research training only can be considered productive when prepared by the scientific supervisor candidates of sciences are highly qualified scientific personnel, ie conduct high-level research, the results of which are recognized by the scientific community; the same is true of the scientific advice (highly qualified scientific workers - doctors). The practical significance of the study results - in the possibility of objective monitoring of research activity of scientific-pedagogical personnel of higher qualification. Methodological bases of research: a systematic, competence, sociological, and metasystem qualimetric approaches. Methods: modeling, methods of quality control, methods of set theory, relations and graphs. Normative base of research: the Federal Law "On Education" (2012), the federal state educational standards of higher education (2014, 2015). The work was performed as part of research projects "Monitoring of the research activities of educational institutions in the information society" (№ 16-03-00382) and "Modern information and educational environment" (16-36-00048) with the financial support of the Russian Humanitarian Foundation from 17.03. 2016.

Description
We have presented a table of analogues of mechanical and electrical quantities of a thermal power plant, which shows the relation between the useful power of the engine and mechanical efficiency, as well as the relationship between engine parameters and regime of its operation; we have also developed an electro-mechanical analogy, which helped to get the expressions linking the useful engine power with shaft speed, engine performance, coefficient of mechanical resistance and mechanical efficiency with speed, coefficient of drag and engine performance. Similar expressions were obtained for the relations of these variables with other sets of parameters. The article also shows corresponding graphs. The expressions for the maximum net power and corresponding speed of rotation was found. Thus, the efficiency isЅ. It is shown that in larger (compared with the extreme) speed, the mode is less efficient than with the smaller, for the same useful power. A method is presented to measure the important characteristics of the finished engine – motor operation and its rotational drag coefficient used in the resulting expressions
