Description
The work is done in a scientific and practical ways to minimize power losses in the transmission of electricity in the interregional distribution networks from the sources to the consumer by the use of tasks, ensuring the gradual improvement in the support program, not only from the standpoint of the efficiency of reduction of transported power loss, but also due to a significant decrease the complexity of the calculations. The resulting shortage of electricity power associated with its transfer to the electricity networks, has demanded the need to find possible ways of reducing the value of electricity losses during transportation, both by improving and by optimizing distribution net-works schemes. Consolidation into a single set of electrical equipment, called the power cluster is connected to the sources of power and energy consumption, make better use of new principles of control technology and the transmission of electricity, on the basis of an automated monitoring system, ensuring the redistribution of energy flows and optimize them. The process of electric power transmission and reduction in electric power loss can be considered on the basis of linear programming problems, and their modification in the form of a transportation problem, and as a result, the transport matrix. On this basis, manipulating the data table, we can find acceptable solutions, well and then determine the best of them. As examples, this work has carried out the study on the basis of the three methods - "northwest corner", the method of minimum unit cost of electricity transport, as well as the method of the potential. The use of these three methods yielded acceptable solutions, to identify the most appropriate for the number of steps carried out at the decision, to reveal that the winner is the potential cost method

METHOD OF POLYMORPHIC VIRUSES DETECTION BASED ON ARTIFICIAL IMMUNE SYSTEM AND GENETIC ALGORITHMS
DescriptionThis article is dedicated to the study of the fundamental properties and components of the immune system such as B lymphocytes, the Tlymphocytes, immune system storage, primary and secondary immune response, immunological training detectors, which will be the basis of the obtained as a result of detection methods of polymorphic viruses using artificial immune systems. Polymorphism of computer viruses is the formation of a malicious program code directly during execution. Thus, it is impossible to create a unique signature corresponding to these polymorphic viruses. A similar classification problem is solved by the immune system of vertebrates, stared again met with the virus, it "remembers" him, and the next time provides effective secondary immune response. These properties of the immune system served as a prerequisite for the use of immune approaches and algorithms for solving the problems of detection of malicious code. The article identified and described their main features, proposed the idea of their implementation and software, system interactions in the immune system revealed such important features, the implementation of which will be effective in solving the problem of detection of malicious code and software. Also, for a more productive system of education is considered a class of genetic, evolutionary algorithms, described by their immediate implementation of site-specific decentralized artificial immune system, built a system of interaction of genetic and immunological algorithms.

PARTICLE SIZE DISTRIBUTION OF ASH OF NOVOCHERKASSK SDPP
DescriptionThe flowsheet purification of exhaust gases in the Novocherkassk SDPP after the electrostatic precipitator on I-th stage of purification set group cyclone, on the II-nd stage of purification - baghouse. To determine the particle size distribution of fly ash, we selected ash from the transport network to the group cyclone, and the in a group cyclone, and in a baghouse. With the help of the microscope "Biomed- 3" we produced pictures of ash particles with different magnification. Granulometric composition of three selected ash samples were determined according to the mass content of particles of different grain size, expressed in percent relative to the weight of dry ash sample taken for analysis. For size fractions from 10 mm to 0.5 mm sieve method is applied without rinsing with water, for size fractions less than 0.5 mm sieve method is applied with water washing. The particle size of the ash mixture, taken up before the cyclone,

Description
We have presented a table of analogues of mechanical and electrical quantities of a thermal power plant, which shows the relation between the useful power of the engine and mechanical efficiency, as well as the relationship between engine parameters and regime of its operation; we have also developed an electro-mechanical analogy, which helped to get the expressions linking the useful engine power with shaft speed, engine performance, coefficient of mechanical resistance and mechanical efficiency with speed, coefficient of drag and engine performance. Similar expressions were obtained for the relations of these variables with other sets of parameters. The article also shows corresponding graphs. The expressions for the maximum net power and corresponding speed of rotation was found. Thus, the efficiency isЅ. It is shown that in larger (compared with the extreme) speed, the mode is less efficient than with the smaller, for the same useful power. A method is presented to measure the important characteristics of the finished engine – motor operation and its rotational drag coefficient used in the resulting expressions

ABOUT SOME CONTROVERSIAL ASPECTS OF CIVIL WAR AND INTERVENTION IN RUSSIA
DescriptionThe authors have devoted some of its controversial aspects, which have been going on for decades in the scientific community, namely, the time-frame of the Civil War, its causes and about the time of its beginning. In addition to these issues, the article is considered the relationship between the socialist parties and their participation in the civil war, the role of foreign intervention in the case of incitement to war and, finally, the reasons of the defeat of the White movement. The authors did not set out to elaborate on all four stages of the civil war, and focused on the examination of its first phase, covering the period from the end of May to November 1918. The main object of consideration the question arose about the beginning of the Civil War. The authors dwell on the various points of view expressed in this historical science, argues with those of them who, in their opinion, do not withstand scientific scrutiny. They speculate about details of alternative embodiments of the historical process, try to consider the option that could have been avoided civil war, if there was a coalition of socialist parties and come to the conclusion that such a coalition was impossible and it looks ephemeral. The authors dwell on the consideration of the role that is played in the raging civil fratricidal war, foreign intervention. They rightly point out that it is military intervention exacerbated and intensified civil war, has extended its time frame, the number of dead and wounded, even more glowing civil and class hatred
