abstract 1011407062 issue 101 pp. 985 – 1004 30.09.2014 ru 989
The reliability of work of the technical systems significantly influences the technological losses of manufacture process. During the counting the availability ratio of the technical system it is recommended to take into the consideration implicit as well as evident breakdowns of all separate components of the whole object. There is a formula for counting technological losses depending on the availability ratio of technical object. Similar formulas for counting losses proceeding of atmosphere and water resources pollution, pollution of soils with hard matters are obtained. Introduced identities bring together reliability of the technical systems and separate components of ecological losses

IMITATION MODELING WHEN ANALYSING THE EFFICIENCY OF AGGREGATES FOR TILLAGE

abstract 1021408066 issue 102 pp. 1017 – 1042 31.10.2014 ru 963
The choice of the most optimal composition of aggregates for tillage for work in a certain economy is very difficult from many determined and casual factors. In connection with what, it is suggested to conduct researches with the use of quantificational and quantifier algebra logic. Also we need minimum influences on ecology, being characterized as a predicate of "minimum of expenses on indemnification of erosive losses of soil". For the agricultural technique of Russia, countries of the CIS and distant foreignness with the well-known norms of making (by the productivity) and expense of fuel imitation modeling is applied, on the method of Monte Carlo (Monte - Carlo Simulation), allowing to build a mathematical model for prognostication of necessary amount of aggregates at different normative agroterms with corresponding damages

INNOVATIVE APPROACH TOWARDS EDUCATION QUALITY ASSESSMENT AT HIGHER EDUCATIONAL INSTITUTIONS

abstract 1061502007 issue 106 pp. 112 – 134 28.02.2015 ru 963
One of contemporary challenge at the educational system is a need to develop new methods and approaches enhancing quality of graduates. Transformations in our country towards market economy make us to compete with own products not only at the level of enterprises, but educational institutions as well. The article shows that the elements of the Theory of Automation are applicable to the quality analysis of the accomplishment of graduates. Issuing of latest regulation documents also supports this hypothesis and encourages the further development of mentioned methodology. In the article, special attention is paid to the funds of assessment tools because of their quality depends on the adequacy and accuracy of the information received further action of the education system. It is also shown that it is necessary to create a situation in which the student can demonstrate skills obtained, which can manifest itself not only in the classroom. Individual competence may appear in extracurricular activities, and evaluate their means can not only leading teachers, and supervisors in the dormitories, responsible for educational work, SRWS leaders, heads of educational and industrial practices, etc. The article describes the method of calculating the total level of formation of competence

APPLICATION OF ELECTRICAL TECHNOLOGIES FOR ENHANCING OF IN-HEAVE MICROCLIMATE

abstract 1061502008 issue 106 pp. 135 – 150 28.02.2015 ru 995
One of the integrative indicators of over-all performance estimation is profitability of the production. It is possible to increase competitiveness of beekeeping production as well as national food security via implementation of efficient electrical technologies. Enhancing of microclimate parameters in hives allows us to enhance the intensity of spring development of bees. The counting of integrate heat losses in heaves with ozone treatment and without the one was carried out. Using the obtained results and graphs we can develop the automation system for in-heave microclimate control. The article presents the graphs of heat losses in a beehive on the outdoor temperature and relative humidity, which were obtained experimental. It is proved that when the outdoor temperature from -15 to 8 ° C and the change in ambient air humidity of 60 to 100% heat loss beehive decrease from 4-5 W to 0.2-0.4 W. It is concluded that treatment of bees by ozone, while reducing the concentration of pathogenic microorganisms, will reduce the energy loss by reducing the air exchange, i.e. improve conditions for the development of the bee colony

APPLICATION OF THE IMITATION MODELING FOR OPTIMIZATION OF CONSISTENCE OF THE CULTIVATION AGGREGATES FOR CROP FARMING

abstract 1061502033 issue 106 pp. 529 – 549 28.02.2015 ru 979
The main indicators of efficiency of a cultivation machine are the following: productiveness and fuel consumption, which depend on complexity of work, operating depth and structure of the machine (type of the tractor and plough). The optimal structure of cultivation aggregate for the needs of each exact farm is complicated to do due to different determined and stochastic factors. In this case, Monte Carlo imitation modeling is proposed to use. As a result of models’ analysis, it is defined that all aggregates could be divided onto 4 groups of efficiency. Curves demonstrating dependence of fuel costs, compensation of losses caused by breakdown of agricultural terms and soil compaction caused by quantity of aggregates are built. After integration of the whole amount of aggregates into a common traditional technology of cultivation and after selection of its characteristics (quantity of aggregates, general fuel costs and losses costs, including fuel costs) it was proposed to split it onto 3 category modes: hard (according to technological mode – 2 or 5 shifts), normal (4-10 shifts), mild (6-15 shifts). The obtained models can be successfully applied in software of on-board computers in tractors and PCs of the engineers as well. Dynamical models for other technological processes in plant breeding could be obtained in the same way. All developed models allow us to make one more step towards precision farming and reduce costs for manufacture of end products

DEVELOPMENT OF MATHEMATICAL MODELS OF AN ELECTRO-ACTIVATOR BASED ON THE DATA ON WATER QUALITY AND REQUIREMENTS FOR WORKING HERBICIDE SOLUTION

abstract 1071503079 issue 107 pp. 1216 – 1234 31.03.2015 ru 914
Based on this analysis, it was found that it was necessary to develop an electro-activator with adjustable parameters. Analysis of the literature showed that there are no analytical expressions relating the degree of activation solutions, conductivity, temperature and geometric parameters of an electro-activator. The article presents a block diagram of the system "Electro-activator - working solution - weeds", a mathematical model of the subsystem "Electro-activator" allows to describe the parameters of the solution at the outlet of the electro-activator and its mode of operation. An expression is derived which allows to determine the critical mode of installation and adjustment range of current management. When exceeding the rated range of the control the main energy will focus on the process of aerogenesis. We have implemented the coefficient of aerogenesis, which has a significant impact on the temperature of the solution in the chamber and an electrically. This factor must be taken into account as well as the approach mode to the critical or exceeded. The calculation for the resulting mathematical model makes it possible to design an electro-activator for a company which has different water sources and apply different plant protection products. Also, in the future, the result of the research will allow developing engineering techniques for calculations

ENGINEERING TECHNIQUES FOR DEFINITION OF PARAMETERS MEASURES OF AN ELECTRO-ACTIVATOR

abstract 1071503080 issue 107 pp. 1235 – 1249 31.03.2015 ru 905
The article presents an engineering method for defining electro-activator parameters. We have developed an engineering method for calculating an electro-activator with improved performance that can reduce the complexity of the design calculations and include a critical mode of the electro-activator at which the process leads to passivation. We have proposed an automated management scheme based on electro-activator functional and electrical schematics. One of the benefits of the resulting model of calculations of an electro-activator is to identify a possibility of automating the process of managing and stable operation. The current in the electro-activator can be adjusted depending on performance. Automatic maintenance of performance and capacity control for the benefit of the cameras is possible, giving an automatic valve with an analog controller. When the temperature rises above or current exceeds the desired value, we can face signaling and a complete shutdown of the installation. The use of temperature sensors, pH, conductivity and flow can be implemented, as well as centralized information collection and development of the control algorithm. Monitoring and maintenance of an electro-activator can be fully automated with the equipment of industrial automation. Also, on the basis of the proposed engineering method for calculating, it is possible to develop a software product. That will allow designing computer simulation when planning an electro-activator
