PROTECTION OF PERSONAL DATA IN THE INFORMATION TRAINING SYSTEMS
DescriptionNowadays, a necessary condition for progress in the field of information technology is wide adoption of standards and technologies of information systems used for hardware and software products. Building software of computing and information systems, based on the ideology of open systems, allows to successfully solve the problems of portability on platforms of various manufacturers, the problem of interchangeability of components and, most importantly, ensures the integration of devices and users in a variety of computing and telecommunication networks. It should be emphasized the fact that to date the successful implementation of any significant projects in the field of information and computer technology, management of information and telecommunications is not possible without coordination of development with existing standards in the field of information systems and, in some cases, the development of new standards. In the transition to integrated computing and telecommunications systems principles of information systems form the basis of technology integration, the establishment of sectoral, regional and national information infrastructures and their interactions on a global scale. Therefore, we can conclude that the technology of information systems today is the working environment in which the priority is the development of information and telecommunication technologies, telecommunication and computer engineering

EXPLORING THE POSSIBILITY OF OBTAINING PECTIN EXTRACTS OF HIGH PURITY
DescriptionThe article describes a possibility of obtaining food pectin extracts of high purity form secondary raw materials such as sunflower anthodiа. The relevance of the use of pectin extracts as independent products or as an ingredient in food products for therapeutic and prophylactic purposes is determined by the high complexing ability of pectin substances in the dissolved form, in comparison with the commercial powder pectin. The use of pectin extracts reduces the cost of the final product by reducing the number of technological procedures. As dried plant material is mainly used for the production of pectin and pectin extracts, the article presents the study of the swelling process of dried and crushed sunflower anthodiа. It is established that the inclusion of the swelling process as a separate technological process for the production of pectin extract from the sunflower anthodiа is impracticable. The study on further processing of vegetable raw materials by electroactivated water system (EAWS) to reduce the content of ballast substances in raw material in relation to pectin and increase the purity of pectin extract is also presented. Some processing options of sunflower anthodia with EAWS of various рН were considered as well. The decrease in the content of dry substances in the processing of plant material that characterizes the decrease in the number of ballast substances is shown. We have also calculated the purity of the obtained pectin extracts

WAYS OF FURTHER MODERNIZATION OF VEHICLES FOR AN AGROINDUSTRIAL COMPLEX
DescriptionThe role of transport in agricultural production is considerable. It is a connecting link in a single technological chain of the agroindustrial complex of the country (RF AIC). In intraeconomic transportation in the RF AIC, along with cars, we widely use tractors. Rational application of wheeled tractors in intraeconomic carriage substantiates the possibility of their movements both on asphalted and dirt roads. A specific share of tractor transport in domestic agriculture amounts 22-27% of the total transport transportations and 50-60% of intraeconomic carriage. There is a high level of the usage of tractor transport in Western European countries and in the United States. In farms of leading Western European countries (Germany, Italy, France and others.) there is about 70-90% of intraeconomic carriage performed by tractor transport. One of the most substantial and difficult tasks is to fight with damage and losses of agricultural production, in which a very responsible role has been assigned to automobile and tractor transport as an important link in the AIC. According to the analysis of materials for the preparation and use of potatoes and apples, more than 15-20% of the products do not reach the consumer. Low quality of the use of vehicles during transportation is a problem. Transport costs in the prime cost of produced products in rural areas reach 30-40% or more. Lowering them will further influence the development of the agroindustrial complex. Thus, the creation of new of scientifically grounded decisions in designs of vehicles for intraeconomic carriage that enhance preservation and performance of potato harvesting and apples in the conditions of Russia's AIC is the actual scientific and technical task. Its solution makes a significant contribution to the development of the country, as well as it contributes to the implementation of breakeven, competitive manufacture

Description
In agriculture the issue of enhancing the efficiency of operation of internal combustion engines (ICE), reducing the costs of maintenance (TO) and repairing (TP) fuel supply apparatus (TA) using the improvement of methods and means of diagnosis is a topical in connection with the aging rolling stock farming and lack of investment. Analysis of the known TA diesel engine vehicles systems showed that the most widespread system is the divided type with multiplunger high pressure fuel pump (fuel pump), while the methods of its diagnosing are laborious, they require partial disassembly and have insufficient accuracy. The mathematical models that characterize the work of a high-pressure fuel pump (fuel pump) use a large number of parameters that significantly affect the quality of dynamics of the change of pressure values of diesel fuel. However, in the materials of previously published articles there were no issues considered assessing the extent of the quantitative impact, performance and features change in the sensitivity settings of the mathematical models on the simulation results, there are no recommendations on the degree of sensitivity and importance of each of the parameters. For a more accurate diagnosis of the fuel supply apparatus of a diesel engine it is advisable to use several methods of diagnosing. The article substantiates development of a mathematical model of a high-pressure fuel pump based on the analysis of modern methods of diagnosing of fuel equipment for autotractor diesel engines

Description
Our research aims at providing new effective control methods for scientific and technical expertise to organizations and foundations that fund research projects on a competitive basis. These methods should provide analytical decision support for group decision making in a distributed environment. In this work, we consider an integral model for knowledge representation – a socio-semantic knowledge network that combines social links and a semantic description of knowledge into a mathematically formalized graph theoretic structure. In terms of actor-network theory, we consider a multimodal network with actors on one of the levels and artefacts (i.e. contexts that express network links) on the other level. In order to represent knowledge domain based on a graph and hypergraph paradigm and fuzzy sets theory, we provide a sufficiently complete set of elements and relations (either trustworthy or partially trustworthy) both between multitype elements and their heterogeneous groups. The formal representation allows applying the model to solve numerous practical tasks such as expert finding, formation of expert groups, expertise refinement, reduction of subjectivity, analysis of an expertise process, analysis of processes within expert groups. Research methodology: social network analysis (SNA), theory of graphs and hypergraphs, fuzzy calculus and fuzzy logic

TECHNIQUE OF CHOOSING COMPETITIVE STABLE BEHAVIOUR STRATEGY FOR AN ECONOMIC ENTITIES
DescriptionThe article gives the analysis of the questions that provide economic entities stable functioning in extreme competitive interactions. The task of choosing competitive stable behaviour strategy of the economic entity on the basis of efficient use of a resource is defined in maximine terms. To solve the problem it is suggested to use the means of a multistage nonzero attrition game and a negative-sum “gain”. The ways to overcome major difficulties of a numerical solution of the formulated extreme problem in connection with its dimension and the kind of an optimizable function that might be discontinuous, nondifferentiable and multiextremal are found out. Due to its discrete behaviour a criterial function is given in terms of Taylor approximation. Derivatives in the direction are calculated to find the pair of mixed strategies that is the solution of the considered game. On the basis of the suggested optimal solving algorithm by means of successive approximation maximine value of the efficiency criterion of the economic entity functioning and optimal distributions of the strategies application probabilities that provide its stable (balanced) “survival” are evaluated. The application of competitive stable behaviour strategies based on maximum efficient use of resources allows economic entities to remain viable and provides balanced competitive environment in regional sectors of economy

ABOUT THE MOTION OF THE VIBROLIQUEFIED SEPARATED LAYER OF GRAIN ON THE FLAT SIEVE OF FINITE WIDTH
DescriptionThe aim of the research is analytical determination of the middle speed of the corn seeds on the flat vibrating sieve of finite width. The object of the study is the process of sorting of seeds of corn on the flat vibrating sieve. The mathematical modeling of the motion of the separated layer of the cereal mixture on the sieve is conditioned by the necessity of intensification of division of grain-growing materials on a flat sieve. Despite the significant progress in the development of mathematical models of the motion of a mixture on vibrated sieve, their further refinement remains an actual task. In particular, in calculation practice, theory in which the width of the flat sieve is considered infinite is used, i.e. the impact on the process of the moving frame of the sieve bed is not taken into account. In connection with absence of estimations of the error brought in by this assumption, the necessity to develop a theory of the movement of the mixture on a sieve of the finite width appeared. For the analysis, the following assumptions were accepted: first, the corn seeds were considered as balls of different diameter, second – the layer of grain on a sieve was considered as heterogeneous viscid liquid. Based on undertaken study it is set that most rational for the achievement of the put aim is application of method of Bubnov-Galerkin. As a result of undertaken research analytical dependences are received for the calculation of flowrate of grain mixture on the vibrational sieve of the final width taking into account separation of the mixture into factions
