THE DEVICE FOR STORING AGRICULTURAL MACHINERY IN PROTECTED FORM IN OUTDOOR AREAS

abstract 1241610017 issue 124 pp. 330 – 345 30.12.2016 ru 397
The carried out analysis studies the influence of various factors on the preservation of agricultural products and shows that it is largely determined by design features of machinery and technological methods of use. The efficiency of agricultural and mobile trailer machines has been forming by service and storage. Low quality of work associated with the storage of agricultural machines is conditioned by the fact that the lack of financial capacity of rural producers on acquisitions of modern equipment and materials for carrying out the preparation of for long storage, and also the construction of modern agricultural machinery storage sites. If a car can be fully or partially protected from the solar radiation, rain and snow, simply by removing it in the room, under a canopy or covered with a protective cover, by the formation of condensation on the surface of the machine units and parts these ways to protect do not work. Enhancing of preservation of agricultural machinery is possible when protecting the vehicles from atmospheric precipitation in the form of snow and rain, influence of solar radiation, and also due to the change heat exchange processes of the machine with the environment that prevents the formation of moisture condensate on its surface, ie. we have to create conditions when cooling rate at which the surface of the machine would be equal to or less the rate of cooling air. This is possible through the use of a special design, which would prevent the intense heat radiation of the machine into the environment, ie, would reflect heat rays using its surface and return them to its surface and thus fulfill the role of the heat shield

APPROACH TO DETERMINATION OF MAGNETIC PARAMETERS OF A CONTROLLED ASYNCHRONOUS CASCADE ELECTRIC ACTUATOR WITH THE SPECIFIED GEOMETRY

abstract 1201606040 issue 120 pp. 575 – 586 30.06.2016 ru 398
The modern level of development of the industry requires creation of more difficult and high-precision systems of an electric actuator allowing executing precisely and correctly the given technological processes. As these devices, we may consider hybrid or cascade systems of an electric actuator. However, for creation of such devices we require new design approaches, or specification and improving of the existing theories and methods of design of classical systems. The main difficulty in calculation consists in determination of parameters of electromagnetic system. In this article, new approach is given in finding of electromagnetic parameters of components of an asynchronous controlled cascade electric actuator taking into account real geometry. This approach was formed during creation of the program complex, which is a part of a system of automatic design

abstract 1211607100 issue 121 pp. 1633 – 1646 30.09.2016 ru 398
The article noted that the aggravation of the problem of economic sustainability of agricultural organizations in the modern market economy, caused by the influence of the complex as a deterrent, and potentially contributing to internal and external factors, showing up at all stages of the reproductive process. Investigation of this problem has allowed allocating and justifying the most important factors, classified in the context of organizational, economic, innovation and investment, financial and social components, affecting the process of ensuring the economic sustainability of agricultural organizations, taking into account the specific conditions of their operation. Among the constraints, we highlighted the high cost of borrowing, the fiscal tax policy, price disparity, lack of working capital, high financial risks and depreciation of fixed assets, low production efficiency, aging staff, lack of highly qualified personnel, and others. Among the factors conducive to economic stability, we defined such factors as loans, incentives, insurance, government support, the intensification of innovation, use of new resource-saving technologies, modernization and reconstruction of production, increasing the responsibility of the business, improving human resources and others. The proposed classification by the nature of influence on the object of control in the context of structural and functional components enables the development of mechanisms and tools to increase agricultural organizations adaptation to the changing environment. The author concludes that by taking into account all the factors and the formation of an effective management system based on agroeconomically harmonious coordination of market mechanisms and government regulation, it is really possible to achieve economic growth that will create the conditions for balanced, sustainable and socially-oriented economic development

AUTOMATED SYSTEM-COGNITIVE ANALYSIS OF ANTIBIOTICS IN VETERINARY MEDICINE

abstract 1401806033 issue 140 pp. 163 – 212 29.06.2018 ru 399
Antibacterial chemotherapeutic drugs, which include antibiotics and synthetic antimicrobial agents, are widely used in veterinary medicine for the prevention and treatment of diseases caused by microorganisms. Antibacterial agents can be classified by type of action and chemical structure. It is also known that when several drugs are used in combination with each other, they interact within the body with each other, which can lead to strengthening or weakening of their action. For these reasons, it is of scientific and practical interest to develop a classification of antibiotics by their characteristics and principle of action (task 1), as well as by mutual compatibility (task 2). The article solves these problems using a new method of agglomerative cognitive clustering, implemented in automated system-cognitive analysis (ASK-analysis). This method of clustering has a number of advantages over the known traditional methods of clustering. These advantages allow us to obtain clustering results that are understandable to specialists and amenable to meaningful interpretation, which are well consistent with the experts ' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods. The article provides detailed numerical examples of solving two problems. The universal automated system called "Eidos", which is a tool of ASK-analysis, is in full open access on the author's website: http://lc.kubagro.ru/aidos/_Aidos-X.htm. Numerical examples of solving veterinary problems with the use of artificial intelligence technologies are placed as cloud Eidos-applications and are available to everyone

SCREE PLOT METHOD AS A BASIS OF SOLVING METROLOGICAL TASKS IN SOCIAL AND HUMANITARIAN KNOWLEDGE FIELDS (ON THE EXAMPLE OF THE OBJECTIVES OF ECONOMICS, PEDAGOGICS AND SOCIOLOGY)

abstract 1291705099 issue 129 pp. 1371 – 1395 31.05.2017 ru 400
The article presents the main directions of the application of the scree plot method in solving metrological problems in the social and humanitarian fields of knowledge (economics, pedagogy, sociology, including sciencemetry). It is known that statistical measurements in socio-economic systems are inextricably linked with the processing of primary homogeneous monitoring information. It is also known that empirical averaging (computation of the empirical mean), as the dominant method of mathematical statistics, is becoming a thing of the past, due to moral aging, inconsistency with modern requirements (primarily to measurement results in socio-economic systems); In science meteorology, this method was replaced by the scree plot method (the Hirsch index and other scientometric indicators are estimated on the basis of this method). Despite its enormous potential, the scree plot method, as an alternative to traditional methods of mathematical statistics, is very poorly used in the social and humanitarian fields of knowledge. The authors of this article have shown that this method can be successfully applied in solving various metrological tasks, not only in science (sciencemetry is a branch of science), but also in economics, pedagogy and sociology. In addition, the authors show modifications of the scree plot method, using the example of measuring (measuring) indicators in the economy, sociology and pedagogy; The relationship between the scree plot method and the theory of latent variables (qualimetry) and database technology is grounded. The authors also substantiate that the scree plot method - the basis for the formation of monitoring indicators that adequately reflect the performance of socio-economic systems. The practical significance of the results of this study is that they can be used in socio-economic and psychological-pedagogical monitoring systems (according to modern views, monitoring is an information management mechanism). Methodological basis of the research: system, sociological, competence, probabilitystatistical and qualimetric approaches (leading methodological basis is the probabilistic-statistical approach). Research methods: modeling; Methods of graph theory, sets and relations; Systemic-cognitive analysis; Methods of qualimetry (the theory of latent variables); Methods of mathematical statistics

SIMULATION OF THE LARGE-SCALE TRANSPORT NETWORK BY PREFRACTAL GRAPHS

abstract 1311707085 issue 131 pp. 1035 – 1045 29.09.2017 ru 400
This work is devoted to a new method for designing large-scale structures of transport networks. The model of a large-scale transport network is built on prefractal graphs. The model of a large-scale transport network is based on the principle of hierarchical organization of territories. A prefractal graph is a finite analogue of a fractal graph combining the properties of a fractal and a graph. Some problems of discrete optimization on prefractal graphs become polynomially solvable under certain conditions. Reducing the complexity of extreme problems on prefractal graphs is due to the fact that on these graphs for some problems, along with the selfsimilarity property, the property of heredity appears. Using this property, it is possible to construct parallel algorithms for problems on prefractal graphs, the complexity of which is orders of magnitude lower than for known successive algorithms
