METHODS OF CHOOSING DIAGNOSED VEHICLE PARAMETERS IN AGRICULTURE
DescriptionThe article presents an analysis of the existing approach to automobiles technical maintenance in agriculture. We have pointed out that in modern conditions it is impossible to forecast the automobiles maintenance operation frequency and as a result its improvement as well. It is obvious that one cannot achieve the considerable increase of maintenance operation efficiency by separate means and there exist the necessity to treat it as a system and use the up-to-date methods to investigate and improve complicated systems. We have made a conclusion that the increase of maintenance operation efficiency is not possible without some rational strategy of maintenance operation and repair. We have shown that the program of maintenance operation and repair being an integral part of automobiles technical maintenance has considerable effect on maintenance and repair quality. As a result, there is some necessity of the developed system of parameters diagnosing and control in technical maintenance and repair. We have shown that to get sufficient diagnose information one needs selection of the controlled parameters which give maximum information about the object technical status taking into account possible characteristics of its operational faults. We have discovered that in order to solve the task it is necessary to have the object’s information pattern, calculation of possible characteristics of the controlled object being in good or bad order due to some parts fault, evaluation of information brought by every parameter and determining parameters to be diagnosed. We have proposed to evaluate the parameters’ information value with the help of information entropy as uncertainty measure that is one of the main concepts of the information theory. Because of solving the task, we have got the aggregate of the controlled automobile parameters orderable according to the amount of information

THE METHODS OF ASSESSING THE QUALITY OF KNOWLEDGE AND LABOR POTENTIAL OF UNIVERSITY GRADUATES
DescriptionKey indicators for employers are the quality of knowledge of graduates and their readiness for practice. The article suggests some methods of assessing the quality of knowledge and labor potential of graduates. Because the quality of training generally depends on the qualification of the faculty, the quality of students' knowledge is to be determined with the results of their learning and the qualification of the teachers who conducted their classes and supervised their final qualifying works. The author's analytical expressions for determining the quality of knowledge and labor potential of graduates, allow employers to choose specialists particularly required for their industry. However, for employers the rate of knowledge and labor potential of graduates of universities are indicative rates. In order to determine the choice of specific graduates, on the University's website starting from the 3rd year of a bachelor degree, we should post the information about the rating of individual students on educational and labor activity. The ratios determine the quality of knowledge of graduates and their labor potential, as well as reviews of employers should be the main indicators for the Ministry of education and science of the Russian Federation, on the basis of which we may assess the effectiveness of the universities, determine their ranking and generate a state order for training of specialists in higher education institutions

Description
The problem of availability and quality of medical care is a priority nowadays. The Medical Centres for Information and Analysis (MCIA) have been created in the regions for the purpose of gathering information about the quality of services rendered and subsequent data are transferred to the Ministry of Health Care of Russia. Regional MCIA are complex and developed systems that solve simultaneously many problems, one of which – the organization of collection, processing, recording and analysis of information on the provision of medicines. It has been established in the course of conducting an analytical review of examination systems of preferential recipes and information protection that the level of automation of routine operations of the MCIA activity of the Krasnodar Region is high, but there is no qualitative information processing. As a result of the comparative analysis it was determined that the automated review of medical prescriptions for privileged drugs allows identifying abnormalities in the reference data without any analytical conclusions about the causes and consequences of the case. Taking into account the fact that in the provision of essential medications there still exists quite understandable demand for software products which automize the routine work of specialists, it remains obvious that the directions of improvement of software products are not implemented fully. In this regard, the present research proposes measures to improve the existing systems by integrating with the information system of medical and economic control of the prescription of medicines

DescriptionThis article deals with the problems and prospects of development of the digital economy of Sub-Saharan Africa. The work will examine the relationship between the development of new information and communication technologies (ICT) and the formation of civil society in the region. The stages of implementation of Internet technologies will be explored. The development in different countries according to national circumstances, understand the basic functions of the new ICT in the development of civil society and freedom of expression and development trends in the region will be studied. Africa itself is not the leader in terms of providing access to a communication area, only 13% (according to research by the World Bank), the inhabitants of the continent using the Internet. But it’s observed in Africa a high growth of the World Wide Web users in a relatively short period. Subsaharan Africa is one of the developing parts of Africa, taking into account the higher interest of the residents, technology is developing faster and the communications is the higher quality, The reason why young people have access to educational, take part in the dialogue with people from different countries, learn about the labor market, are part of a large community of interest, and in consequence are more critical of what is happening around. The article gives a definition of "digital economy" ; the graphs and charts that reflect the level of ICT development and participation of civil society in their distribution ; the participation of civil society in their dissemination ; review: dynamics of development of the digital economy, dynamics of the African telecommunications market, mobile market and all in the region's economy, the incredible pace of development of Internet technologies, socio-economic problems and challenges, the emergence of new jobs, new technology is providing the usual banking services, the emergence of e-government and its impact on the quality of customer service, the appearance of new educational technologies and resources, prospects of technology development and society under the influence of these technologies and more are considered. the data of the World Bank, the UN, Wireless intelligence, PwC, Internet world stats, UIT, GSMA, eMarketer, CNUCED and others. It is a question of purely African technologies like M-Peza, SenGeoSante, Medafrica, Mpedigree, Matibabu and others are used in the article

TECHNICAL AND ECONOMIC PERFORMANCE OF VM32 MACHINE MULTI-COMPLEX
DescriptionThe article describes problems of economic growth of the Russian Federation, development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, creation and development of import-substituting production of engineering resources that relate to dual-use technology and are in the most demand by strategic organizations of machinetool, machine-building and military-industrial complexes (aircraft engineering, rocket and space engineering, shipbuilding and power engineering). We proposed some measures to improve the accuracy in the manufacture of complex and large-sized parts with weights up to 100 tons. Precision machining of the workpiece surface is directly dependent on the tooling, quality and quantity of the cutting tool (CT), as during the processing the CT wears and must be replaced. We have described the modernization of multi-machine complex and ways of increasing the accuracy, the change in the kinematics tool supply to increase the number of tools used in the processing. We made calculations of the new chain drive of the tool supply. The proposed modernization of the tools will increase the instrument amount that allows increasing the accuracy of manufacturing products. We have also made calculations of the economic effects of the tool supply modernization

06.00.00 Agricultural sciences
DescriptionIn the current economic conditions of the import substitution, special importance is given to the search for new feed sources, methods of preparing them for feeding, the use of biologically active substances and enzymes. At the forefront of feed production is rape as breeding work with this culture has showed positive results. Currently, selectionists have bred yellow double-zero "00" varieties of rapeseeds free of erucic acid of "Canole" type, that have low glucosinolate level. The development of new and modern technology standards are required for preparation them for feeding, since they are fundamentally different from the previously used rapeseed varieties and have fewer restrictions for feeding to different types of farm animals and poultry. The article presents a fairly lengthy and reasoned review of the literature of a large number of authors on the topic, as well as given rapeseed market analysis, rational and advanced methods of preparing rapeseed processed products for feeding to young and adult animals. Much attention is paid to the use of a variety of biologically active substances and enzymes, which improve digestion and absorption of nutrients from rations with rapeseed processingproducts, increase productivity and reduce feed costs per unit of production. The use of processing products of rapeseed improves the profitability of livestock production. Feeding of rapeseedcake to cattle increases the protein content and volatile fatty acids in the rumen content, increases the number of infusoria and decreases ammonia levels. The inclusion of rape forage in diets of farm animals and poultry improves hematological parameters. Products of rapeseed processing of the varieties with low glucosinolatesa1re recommended for the rations of farm animals and poultry depending on the species, age and physiological state

Description
The article presents an algorithm for constructing an expert system for quantitative bankruptcy risk estimation of small agricultural enterprises. Fuzzy logic analysis methodology in the form of fuzzy inference system was put as a basis for this development, classically including five steps: fuzzy rules base forming, fuzzification, aggregation, intensification, defuzzification. All the calculations were performed using MATLAB 2012 software package including Fuzzy module. Demand and costs of production were proposed as main factors influencing bankruptcy risk. Quantitative estimations of input parameters were determined by 100-point scale on the basis of expert estimations, and after that variables were fuzzificated in the form of trapezoid numbers as most common in fuzzy logic analysis (after triangular). Besides quantitative estimation of bankruptcy risk a surface of fuzzy inference was constructed, allowing to determine dependence between output variable’s values and input variables’ values of original bankruptcy risk model, as well as necessary values of input variables values to reach acceptable level by experts

DescriptionThe article has considered the influence of modern climate changes on the intensity of erosion processes within the boundaries of the basic landscapes of the region. It has given the results of the spatial distribution of the rainfalls. The most noticeable climate changes of the Bryansk region are reflected in the decrease in the activity of erosion during snowmelt due to the lower amounts of snow and soil frost depth. In the area, the dynamics of rainfall does not detect a single trend. The processes of erosion and deflation are studied in the relationship, the manifestation of these processes on the territory of the Bryansk region. It has published the results of the risk analysis of erosion and deflation on forest soils of the region and justified the application of G. V. Bastrakov’s method for modeling erosion-resistant agricultural landscapes. This approach has a number of advantages over the other known methods. In our case, regardless of soil and climatic and geomorphological conditions, the challenge is to ensure such events in which erosion resistance of the land will not be below a critical value. The research results are the initial data in designing soil conservation activities on the territory of the Bryansk region. The obtained data of the erosive properties of soils from climatic changes enable the study and forecasting of the development of agricultural landscapes of the region in the medium term
