AUTOMATION OF FUNCTIONAL-COST ANALYSIS AND THE METHOD OF "DIRECTCOSTING" ON THE BASIS OF ASC-ANALYSIS AND "EIDOS" SYSTEM (AUTOMATED CONTROL OF PHYSICAL AND FINANCIAL COST EFFECTIVENESS WITHOUT SUBSTANTIAL TECHNOLOGICAL AND FINANCIAL-ECONOMIC CALCULATIONS BASED ON INFORMATION AND COGNITIVE TECHNOLOGIES AND THE CONTROL THEORY)

abstract 1311707001 issue 131 pp. 1 – 18 29.09.2017 ru 4
Techniques of value analysis and "Direct-costing" are well-known and popular. The ideas and principles of value analysis and the method of "Direct costing" are very similar, if not identical. On the one hand, these ideas are very reasonable, well grounded theoretically and proved its effectiveness in practice. On the other hand, the wide use of these methods is hampered by the difficulty of obtaining large amounts of detailed technological and financial-economic information, as well as the need for careful research by competent professionals, well-versed in substantive subject area. This is the contradiction between the desire to apply the methods of the value analysis and "Direct costing" and difficulty to perform it in practice. This contradiction constitutes a real problem and may often be discouraging and frustrating. In this work, we propose a simple and effective solution to this problem, theoretically well-informed with all the necessary methodological and software tools and widely and successfully tested in practice. The proposed solution is based on two simple ideas: 1) instead of collecting and holding a meaningful large amount of technological and financial-economic information we might apply approaches, pleasant management theory; 2) to create systems for automated control of natural and financial-economic efficiency of expenses we might use the automated system-cognitive analysis and its software tool – an intellectual system called "Eidos". In the name of the specialty 08.00.05 – Economics and national economy management, there are such words: "management of enterprises, branches, complexes, innovation." The use of the term "Management" implies that there is a model that reflects the influence of factors on the object of control, and there is the management system making decisions based on this model. However, as a rule, the dissertations in this field have nothing of this, except only financial and economic calculations. The article proposes an approach based on the control theory, removing this disadvantage

abstract 1311707004 issue 131 pp. 29 – 44 29.09.2017 ru 7
The article presents the theoretical and experimental research of the guide wire, made of polytetrafluorethylene, for sieve system of air grain cleaning machines. We have calculated trajectory of movements of the components of piles of sunflower seeds in the vertical pneumatic channel when they are vanishing from the surface of the guide wire at its various parameters. Specifying the location of a guide wire polytetrafluorethylene in air-sieve grain cleaning machine was carried out in an experimental setup. The guide wire of polytetrafluorethylene was installed in three locations: 1) at a distance of 20 mm to the pneumatic channel; 2) on the levels with the pneumatic channel; 3) at a distance of 20 mm inside pneumatic channel. The approach of the guide wire into the inside of the pneumatic channel in the experimental setup the quality of sunflower seeds increased with 97.61 to of 99.08 %. The content of organic impurities, milled and broken seeds in the pile decreased respectively from 1.83 to 0.21 %, to 1.29 0.66 % 0.51% to 0.25% in the manufacture of wire made of polytetrafluorethylene. To increase the purity of the seeds of the main culture we use a photoelectron separator, and the received seeds for animal feed were in the form of sunflower cake produced on screw presses. As a result of carried out experimental and theoretical researches it is established, that the guide wire shall be made of polytetrafluorethylene and are placed inside the pneumatic channel at a distance of 20 mm and an angle of 40°, which allows to improve the quality of the seeds material and increase the speed of their input to pneumatic channel air-sieve grain cleaning machines type MVU-1500

THE RESEARCH OF PARAMETERS OF WOODEN CHIP COLORING

abstract 1311707006 issue 131 pp. 45 – 55 29.09.2017 ru 5
This work presents main kinds of colourants and methods of painting wood particles. Based on wood structure analysis, it was revealed that hard wood, possessing tracheides and vessels as conducting elements, have the optimal capacity for coloration, in comparison with coniferous trees. A methodology was developed of cloning wooden particles, in the form of chips, with forced immersion in order to obtain established parameters of saturation and brightness. The experiments were conducted with chips of 15-50 mm long, 5-20 mm wide and 3-7 mm thick. The composition of colouring agent included water, acetic acid, and water-emulsion colourants of different types and colours (№1 – colour code (red, yellow, and brown) №2 – colorant (lilac and orange) and №3 – paint). Experience has shown the needed concentration of liquors and mass percentage of compounding ingredients. The research was undertaken to study concentration dependence on the time of allowance and saturation. In consequence of colouring experimental batches of chips, a painting saturation of 4-9 points was obtained at the allowance of 120 and 140 seconds. Dependence of brightness from solubility was determined, with high correlation between given parameters on Pearson Criteria (more than 0.9). Comparative analysis made it possible to discover that the better colouring of particles is created with the red paint. In this case maximum colouring effect is achieved with liquor of water-emulsion paint. Subsequent to the experimental results, a design of installation for colouring wooden particles was developed and patented

PERSPECTIVES AND FEATURES OF OPERATION OF SOLAR PV PLANTS

abstract 1311707007 issue 131 pp. 56 – 68 29.09.2017 ru 3
Currently one of the promising areas to significantly improve efficiency of energy saving is the introduction of renewable sources of energy into the energy system. In the field of solar energy, we consider solar photovoltaic power plants with direct conversion of solar radiation into electricity using solar panels as the most promising ones. The article examines the main factors that reveal the prospects of applying solar photovoltaic power plants. It also discusses the main advantages and disadvantages in comparison with traditional and other renewable energy sources. To improve the operational and technical characteristics of solar power plants in their structure significantly, it is proposed to use new components. Stand-alone inverters for single-phase transformers with rotating magnetic field will reduce the number of power electronic devices in the conversion circuit; they will simplify the system of control and protection, reduce electromagnetic interference and improve overall efficiency and reliability of the converter of the solar power plant. In addition, the modular design of solar power plants will also increase the reliability of the power system due to redundancy of the major functional elements. It is also important that the construction of solar power plants in a modular way enhances maintainability of the system, it significantly reduces the time for maintenance and troubleshooting in emergencies; it simplifies the task of changing its structure depending on requirements of users. The article reveals peculiarities of work and the main benefits from the application of solar photovoltaic power plants

abstract 1311707010 issue 131 pp. 100 – 113 29.09.2017 ru 3
In the article we consider severe conditions of operation of forest cars caused by the difficult land relief and service dirt roads which are badly equipped, as a rule, abounding with roughnesses, obstacles in the form of large superficial roots, stones and boulders, frequent turning movements, steep ascents and descents, considerable cross biases, hollows and boggy sites which lead to increase in consumption of fuel by 1,5-2,0 times and to cutting-down of their life cycle. Ways of increase in their efficiency by equipment by the recuperative mechanisms providing reuse in working process unproductively disseminated to the environment energy, and also promoting increase in reliability and simplification of a design of such cars are analyzed.

MATHEMATICAL AND INSTRUMENTAL SUPPORT OF A POST-GRADUATE EDUCATIONAL PROCESS

abstract 1311707016 issue 131 pp. 162 – 177 29.09.2017 ru 4
Education was always an important part of the development of the individual and society, because education is the process of the formation of mind and character. Each level of education currently requires increased attention, since the quality of life of future graduates directly depends on the quality of the provision of educational services. Despite the fact that most of the educational process is formalized by educational standards, regulatory documents and local acts of educational institutions, this area continues to need both automation and the development of various models, methods and techniques, the use of which will greatly optimize the implementation of the educational process. There are few software products, models and methods that assess the quality of education and the educational process in general, aimed at individual elements of the educational system. In all the existing, basically, there is only support for working with bachelors, slightly less often with masters and very rarely with graduate students. This article describes methodological approaches to assessing the achievements of graduate students, as well as an information system for supporting the educational process of graduate school

The aim of the research was to develop a geographical information system (GIS) for monitoring soil fertility based on calibrated remote sensing data within Rostov region. The possibility of developing a geoinformation system for irrigated agrolandscapes monitoring based on modern computer geoinformation technologies for problems solving of reclaimed territories management in cooperation with other automated information technologies is considered. An example of selecting main degradation processes for the irrigated agrolandscape within Rostov region boundaries, the main possibilities of the system and the proposed directions for its development are presented. To develop a geoinformation monitoring system, the ArcGIS 10.4.1 for Desktop software package has been selected. Monitoring GIS includes remote sensing data obtained from the VEGA-Science satellite monitoring service. The technology for creating a geodatabase for degradation processes monitoring, necessary for rapid analysis of information and time-saving on collection, processing and calibration of data bulk is introduced. As a mapping principle, graduation of farm fields by intensity of land degradation processes was used. GIS monitoring includes multi-layer digital maps and data attribute tables characterizing the main indicators of soil fertility and crop seeding development. The use of GIS technologies with satellite data will significantly reduce the complexity of field survey data processing by data processing automation and is promising for developing computer monitoring systems for irrigated agro landscapes. Farm specialists are offered a convenient mechanism not only for data accumulation, but also for maintaining fields’ history with reference to the yield year. Analysis tools allow performing data spatial and logical queries, to run samples and reports

abstract 1311707031 issue 131 pp. 326 – 386 29.09.2017 ru 2
Assessment of barley for the blotch incidence is traditionally carried out by visual determination of leaf damage with the help of the available expert – phytopathologist , and with the account scales which allows to characterize a variety for resistance or susceptibility to the studied disease in field conditions. This method has a number of disadvantages that are proposed to be overcome by developing a new tool of a phytopathologist. The measuring tool of a phytopathologist should provide high accuracy of the assessment of plants damage caused by the disease, and the measurement procedure should be quick and easy. The aim of this work is to develop a mobile tool of a phytopathologist for quantitative fast assessment of winter barley leaves damage caused by blotch in field conditions. To achieve this goal the following tasks should be fulfilled. Objective 1: introduce the idea and concept of problem solution; Objective 2: justify the choice of method and solution tool; Objective 3: apply the selected method and tool to solve problems, i.e. to perform the following steps: – cognitive structuring of the subject area; – formalization of the subject area; – synthesis and verification of models; – improvement of the quality of the model and choice of the most reliable model – solving diagnostics problems within the most reliable model (classification, recognition, identification), decision support and research of the simulated subject area by studying its model. Objective 4: describe the effectiveness of the proposed solution. Objective 5: examine the limitations and disadvantages of the proposed solutions of the problem and prospects of its development by overcoming those limitations and disadvantages.
