Description
This article is dedicated to the study of the parameters of the artificial immune system for solving the polymorphic viruses’ detection problem. The goal is to define a vector of the immune system parameters that would ensure the minimum number of errors of the first kind, the minimum number of errors of the second kind and the maximum percentage of polymorphic viruses’ detection. That is, the most accurate classification of them as a malicious code, in relation to any theoretically possible vector of parameters of the artificial immune system. A distinctive feature of the studied artificial immune system is the use of a class of genetic algorithms that provide more efficient training of detectors. The configurable parameters of the system are: the algorithm for determining the proximity of the detector and the pathogen, which can be realized by determining the Levenshtein distance or by the method of adjacent bits; as well as the method of implementing the crossing-over operator, the method of implementing the mutation operator, the method of implementing the selection operator, the algorithm for determining the proximity of the detector lines. In addition, the article considers the expediency of using a distributed network of several nodes, each of which will have an immune system that will exchange data with other nodes of the network. As a result of the research, a set of optimal parameters was obtained in which the system achieves the maximum accuracy of recognition of polymorphic viruses

Description
At the nodes of the various machines, we use plain bimetal bearings: a steel base - antifriction cladding layer. Bimetal bearings have increased performance. One of the ways of making such bearings is the way of centrifugal bimetallization with heating of the independent electric arc. An important requirement of this technology is a uniform heating of the workpiece along the entire length until the formation of a continuous layer of the molten cladding material. The process of bimetallization require temperature control, since within the movement of the electric arc, low heat or high heat are possible due to heat dissipation from the ends of the workpiece in the installation and from the outer surface of the workpiece to the environment. A viable option the temperature control of the heat process of bimetallization for industrial conditions is to control the temperature of the outer surface of the steel base. It is necessary to solve the heat problem of the relationship between the temperature on the surface of the workpiece with the temperature on the boundary layers. For this purpose the numerical solution of the mathematical model of the thermal process, which includes the heat transmitting equation of Fourier and heat transfer at the ends of the sleeve according to Newton's law. The equivalent coefficients of heat transfer are obtained based on calculated and experimental thermograms. This is a time-consuming work. To minimize the time of fixing the boundary value problem of the thermal process of bimetallization, in this work we present the preliminary modeling based on the analytical solution of the thermal task of bi-metallization

Description
The article formulates and solves the task of discrete control in the thermophilic stage of the composting process. It is shown that considering the relay control entity to maintain specified process conditions requires the organization of the sliding mode. We have solved the problem of minimizing the temperature deviation of the substrate from the set values and the deviation of the oxygen concentration in the gas phase of the bioreactor from the specified values. The article shows the algorithm to compute the discrete control of the composting process in the thermophilic stage. This work was prepared in the framework of the scientific project 16-48-230441 a(R) "Mathematical modeling of the processes occurring in the automated installation for year-round production of organic fertilizers in the conditions of the Krasnodar region", financed by RFBR and the administration of the Krasnodar region

Description
The mechanical activation allows creating a active state in a solid, opening the prospect for holding and accelerating the chemical reactions between solids and getting materials in a nonequilibrium state. As a result of mechanical activation of the powder compositions of the active phase transformations occur in them, which lead to the formation of solid solutions and various intermediate connections, providing dispersion and dispersion hardening of materials included in the composition. The results of the study of the granulometric composition, the phase transformations and structure evolution in multiphase materials with SME Ni-30%at.Ti-20%at.Hf and Ni-33%at.Ti- 18%at.Zr at different stages of the process of mechanical activation carried out in planetary ball mill the centrifugal type is represented in the article. During mechanical activation, a composite mix is assimilated by the particles of processed material input of mechanical energy in the form of new interfaces, defects of the crystal lattice. At collision of particles and grinding bodies in contact high local temperature and pressure occur, which in some cases can lead to melting of the most fusible components. When a local increase in temperature between the particles of titanium, hafnium, zirconium and carbon solid-phase reactions become possible due to diffusion of atoms of one component into the crystal lattice of the other. Experimental studies have shown that the use of mechanical activation allows creating an effective technology of preparation of the starting material for high-speed flame spraying

Description
The article deals with the study of vehicles impact on the environment, since one of the main causes of air pollution are cars with internal combustion engines. One of the most important measures in the fight for clean air is the creation of an environmentally friendly transport. From this point of view, the most promising is the electric car, as the only solution to the problem of atmospheric pollution. In this article, the history of the development of modern electric vehicles, the advantages and disadvantages of their design, as well as the possibility of introducing electric vehicles into everyday life are considered. After the analysis, it was concluded that, in spite of the obvious advantages and the huge path that electro mobiles went through in their development, humanity is still not ready to refuse from cars with internal combustion engines, opting for electric vehicles

THE IMPLEMENTATION OF THE CONCEPT OF "ELECTRONIC GOVERNMENT" IN HIGHER EDUCATION
DescriptionThe article describes the current state of the transition to paperless exchange of documented information. The general trend of application of information technologies in the field of document management is linked to the concepts of "electronic government" and "information society". The article gives an overview of the legal and regulatory framework the concept of "electronic government" in Russia. We present the dynamics of modern forms of communication and creating unified information space to ensure efficient, effective interaction of society and the state, including the transition to work with documents in electronic form, on education and science. The author has conducted a detailed analysis of the functioning of the module of "Interaction" between the Ministry of education and science and its subordinate organizations; we have also identified technological features of exchange document information. Based on the analysis, we give the evaluation of the implementation of the module of "Interaction"; we emphasize the urgency and high efficiency of information exchange, as well as comfort for users

MODEL OF MANAGEMENT SYSTEM OF LABOR PROTECTION OF A MACHINEBUILDING COMPANY
DescriptionThe article considers a combination of the process-based and systematic approach in the management of OSH at the enterprise for the development of the OSH management system model. The OSH management system is created by the enterprise based on the model provision, the branch requirements and recommendations of the current standards. Features of the system are determined by the state of the external and internal environment of the enterprise (context). The context forms the basic requirements for the inputs of the system and determines its capabilities. An analysis of the context of the enterprise makes it possible to identify the system: describe its inputs and outputs, identify key stakeholders and consumers. Based on this analysis, a model of the OSH management system is suggested, which, in analogy with the modern model of the quality management system, allows us to identify the place of the OSH in the context of the organization, and also to clarify the interaction of the main groups of OSH
