Description
The article contains an analytical overview of the causes of local washouts on hydraulic installations of Don highway networks. One of the major outlet structures of the main canal is the terminal resets in Sadkovskaya gully (Veselovsky reservoir 1115+79), with a maximum flow rate of 50 m3/sec, designed for irrigation and desalination of Veselovsky reservoir. To analyze the effect of the liquid on the bottom of the outlet structures we need to know the kinematic parameters of the liquid in the channel. Until now there are no universal correlations, which would allow calculating these parameters. The mathematical dependences allow analyzing the impact of water flow on the bottom of the spillway constructions of melioration canals. Modeling of local scour of channels is based on a thorough analysis of the causes of this phenomenon. The main ones are the kinematic parameters of the liquid, the speed and the propagation direction of fluid flow, structural features of the channel. The mathematical dependences allowed us to identify the following parameters that influence the degree of local scour at end spillway structures on melioration channels: the rate of flow, the degree of compression of the stream size, flow, shape, and movement of sediment, depth and shape of the supports in the plan and cross section, the shape of the hydrograph, the angle of the jet, duration of standing high water levels in Sadkovskaya balka, etc

SIMULATION OF NONLINEAR COLOR OSCILLATIONS IN YANG-MILLS THEORY
01.00.00 Physical-mathematical sciences
DescriptionThe article presents the simulation of non-linear spatial-temporal color oscillations in Yang-Mills theory in the case of SU (2) and SU (3) symmetry. We examined three systems of equations derived from the Yang-Mills theory, which describes the transition to chaotic behaviour. These transitions are caused by nonlinear vibrations of colour, depending on the model parameters - the coupling constants and the initial wave amplitude. Such transitions to chaotic behaviour by increasing the parameters are characteristic of hydrodynamic turbulence. A model of spatial-temporal oscillations of the Yang-Mills theory in the case of three and eight colors. The results of numerical simulation show that the nonlinear interaction does not lead to a spatial mixing of colors as it might be in the case of turbulent diffusion. Depending on the system parameters there is a suppression of the amplitude of the oscillations the first three of five colors or vice versa - the first three five other colors. The kinetic energy fluctuations or shared equally between the color components, or dominated by the kinetic energy of repressed groups of colors. Note that the general property of physical systems described by nonlinear equations in the Yang-Mills theory and hydrodynamics is particularly strong in the formation of quark-gluon plasma and hadrons jets, when the Yang-Mills is involved in the formation of hydrodynamic flow. Note that there is a relationship between the Einstein and Yang-Mills theory, on the one hand, Einstein's equations and hydrodynamics - on the other. All of this points to the existence in the nature of a general mechanism of formation of a special type of turbulence - geometric turbulence

DIAGNOSTIC OF ANOMALIES IN DATA-PROCESSING NETWORKS WITH USE OF VARIETY OF INFORMATION EXCHANGE
DescriptionThe work is devoted to searching efficient detection methods of anomalous state in data networks. There is a structure of modern informational attacks detecting system. There are short review and analysis of information system network security facilities. Two main technologies of attack detection are described: anomaly detection and misuse detection. It is shown that every detection of anomalies is based on assumption that anomalous behavior is deflection from normal profile of behavior. It is hard to implement this technology, although there is some progress when expert system, fuzzy logic and so on are used for this purpose. Action patterns or symbols assets which describe anomaly activity are used as attack signature in misuse detection method. Author offers to use benefits of both methods for solving the problem

Description
The problems of the increase of the economic stability of specialized fruit-growing organizations of the Krasnodar region are considered in the article. The analysis of the condition of the branch showed that for the last years the natural-climatic conditions lead to the frost-killing of stone fruit-tree gardens more stably and allow obtaining only the gross yields of large fruits. The total area under large fruit gardens in the region for the last five years has changed slightly and makes up 17896 ha in 2013. At present time in the Krasnodar region only 58 agricultural organizations have their own gardens and 13 of them are highly specialized enterprises with the share of gain from sales of fruits in 78%. However, the narrow specialization of farms increases the risk of obtaining of losses and the initiation of financial problems under unfavorable weather conditions. To obtain the stable high financial results is necessary to get the optimal combination of different branches and types of produce allowing the minimization the production risks. The emerged tendencies of the branch’s development, currency fluctuations and the prohibition of the import of agricultural produce from the countries of the EU permit to assess the perspectives of horticulture’s development in the region optimistically. In the article there were given the recommendations to obtain the stable development of the branch. There was marked the necessity of the maintenance of optimal correlations of branches and types of produce in specialized organizations, the application of modern agro-technological arrangements for obtaining of stable fruit yields, the necessity of state support as subsidies for the laying and the maintenance of gardens and in the creation of structures providing the guaranteed produce sales as well

Description
The author’s concept of improving the efficiency of the use of information ressources in the international brands management in the global consumer market is considered. The idea of the concept is to create a new intelligent automated marketing information system of the organization and management of information resources and their adequate (semantic-linguistic, logical and statistical analysis) use in the management of international brands in the global consumer markets. The core of this system is a domain ontology that potentially makes possible to control and transfer an experience in the marketing environment. It is concluded that with further development of the concept, in particular on progress in the structuring of information and knowledge of the subject area, with success in the selection and formation of rules of logical inference, and from the success of the presentation in their native form will largely depend on building an effective intelligent automated training of marketing information systems

ORGANIZATION AND MANAGEMENT OF A WORKFLOW, ITS MAIN STAGES
DescriptionThe topic of document circulation is viewed in this article and is considered significant as the success of any organization depends on the correct choice of technology. In modern conditions the work with documents should be improved to reach high management efficiency since every management decision is always based on service documents. The organization of work with documents affects the performance of the administrative staff and work culture of managers. The success of management activities in whole is largely dependent on the way of maintaining documentation. Properly organized document circulation strengthens control functions of accounting, accelerates the drawing up of accounting reports and increases the efficiency of accounting. Therefore, the accepted system of documenting should reflect the sufficiency of all the economic activities of an organization and facilitate the identification of hidden reserves. The reflection of economic activities should be based not only on their legal form, but also on their economic content and business conditions. To organize document circulation means to develop forms of primary documents, accounting registers and reporting forms other than standardized, to create a schedule of document circulation, to determine the mechanism of taking documents to accounting and to choose the system of document processing and the order of storage. The documenting of business transactions is one of the distinguishing features of accounting as it allows monitoring economic processes. Thus, the importance of the proper document circulation is obvious because it plays an important role in every company. Its improvement and proper control allow getting the necessary information to make different kinds of management decisions, but its misuse leads to financial and criminal liability

Description
In this article some features of standard regulation of a legal status of public servants of civil department in the XIX century are considered. The author notes that legal status of the public servant is the main component of system of legal support of public service. In this regard, theoretical approaches to understanding of such category of law as "legal status" are investigated. The scientific and legal category "legal support" can be considered as in wide, and in a narrow sense. We suggest understanding such system of the social and legal elements able as legal support to influence formation of precepts of law and their practical realization. Modern scientific approaches to definition of the legal category "status" are characterized by sufficient different aspects; there is no unity of opinions that allows drawing a conclusion on difficult multicomponent system of elements of the status of public servants. Legal status of the public servant - the sphere of realization of the rights and duties, legitimate interests, legal responsibility, guarantees. The office legislation in the Russian Empire in details regulated features of legal status of public servants. We have prepared a massive layer of legal acts which was improved further and, in fact, in the changed form found the reflection and during the Soviet period of development of institute of public service in spite of the fact that as a result of revolution of 1917 all regulations were cancelled. Elements of legal status of public servants were accurately defined and designated: the rights, duties, guarantees, a ban and restrictions, legal responsibility that was absent at the legislative level earlier

ECONOMIC-MATHEMATICAL METHODS IN CONTROL OF INDUSTRIAL AND ECOLOGICAL SAFETY
01.00.00 Physical-mathematical sciences
DescriptionWhen considering the ecological safety of industrial productions, territory, etc., we usually allocate the constant (permanent) risk and the accident (emergency) risk. Permanent risk is given by the used technology, and cannot be changed substantially. Emergency risks are associated with uncertainty, in contrast to the constant risks. Let in adopted mathematical model the uncertainty is probabilistic in nature, and the loss describes as one-dimensional random variable. The distribution function of the loss, as a rule, is not normal. We have discussed in detail the seven characteristics of accidental loss: expectation; median and, more generally, quantile; dispersion; standard deviation; coefficient of variation; a linear combination of the expectation and standard deviation; the expectation of the loss function. Risk management may be to minimize these characteristics and their combinations (in different variants of multicriteria optimization). For example, in the two-criteria formulation it is required to minimize the expectation of loss and the standard deviation. Two-criteria formulation one way or another is reduced to a one-criteria formulation. In addition to probabilistic methods of risk modeling, sometimes we consider methods for describing risk using by means of objects of non-numeric nature, in particular qualitative characteristics, concepts of the theory of fuzzy sets, interval mathematical and econometric models and other mathematical tools. The main problems of the theory and practice of ecological insurance have been discussed

MODEL OF INFORMATION SECURITY FOR CONTROL PROCESSES OF COMPUTER NETWORKS
DescriptionIn order to improve the security of information transfer we have offered one of the possible approaches to modeling process control computer networks with elements of intelligent decision support. We proceed from the graph model of network nodes which are network devices with software control agents, and arcs are logical channels of information exchange between the equipment computer systems. We built an addressless sensing technology which ensures the completeness of monitoring of all network equipment. To classify the computer networks state we provided a method for calculating the values of reliability. Development of signal mismatch triggers the control cycle as a result of which the adjustment of the state of network equipment. For existing tools we proposed adding network control expert system consists of a knowledge base, inference mechanism and means of description and fill in the knowledge base
