INVESTIGATION OF NOISE AND VIBRATION OF CUTTING CIRCULAR SAWS
DescriptionThe article presents the results of theoretical studies of noise cutting circular sawing machines. Practical calculation of the noise spectra is based on the determination of the dependency of the sound pressure of the noise sources of the object of study. In the sound system, circular sawing machines sound energy is emitted by the following sources: disc cutter and the mandrel. Therefore, the dominant noise sources should be allocated to the technological subsystem "tool – mandrel” with a bit less rigidity than the carrier system of the machine and directly receives the cutting forces when milling. Thus, it is possible to reduce sound pressure levels in almost two ways: by increasing absorption production facilities and (or) decrease in sound pressure of the noise source. In this work, we have justified the second way – reduction of the intensity of acoustic radiation of the source

Description
The work is scientific and practical in nature, same as the discussed process of optimization of power losses in power networks based on the use of the transportation problem, namely the rules of the minimum element of the transport matrix, which is a valid solution. The mechanism of the improvement of the obtained feasible solutions to the tasks focuses on using the potential method, assigning each row and column of the matrix their corresponding potential. Using a basic variable and manipulating the elements of the transport matrix according to a specific algorithm, we implement the construction of a new support plan. Based on the plan and its acyclic, we build two cycles and determine the values of the estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes it easy to program all computational operations and quickly obtain the result of the optimization of power losses in the design of the electricity network, thereby reducing the economic and technological costs. As a result of joint use of transportation problems and potential method, we could find the optimal solution based on improved solutions more efficiently, and a scheme of optimal electric network. As consumers, in practice, there may be urban and agricultural, industrial enterprises, regional and district subordination, including industrial, agricultural and individual customers

Description
This article proposes an approach to teaching mathematics in high school, based on the application of application software packages, which is especially relevant in connection with attempts to transition in the upper grades to profile education, when the student chooses the direction of more in-depth study of subjects, based on his own inclinations. The substantiation of necessity of development of methodical positions and recommendations on use of packets of applied programs on lessons of mathematics in the senior classes of high school is given. The analysis of existing packages of applied programs for teaching mathematics in high school is carried out. During the research, packages used for solving mathematical problems are considered: MS ESCEL, STATISTICA, MATCAD. Known packages of applied programs are classified according to groups of applications in mathematics lessons. Approaches to the use of application packages in math lessons during the pedagogical experiment have been tested. The pedagogical experiment was conducted on the basis of the State Budget Professional Educational Institution of the Krasnodar Territory "Beloglinsky Agrarian Technical Technical School". The analysis of the results of approbation is carried out and recommendations are made on the application of application software packages in mathematics lessons in high school

Description
The article analyzes the features of ethno-political conflicts in the 21st century, originating on the territory of the post-Soviet and post-socialist space; considers the format, structure, purpose and reasons for intensification; reveals the nature and mechanisms of inter-ethnic confrontations, the reasons for their escalation in certain historical periods, the similarity of the "scenarios" of their development, the role of external and internal factors in the outbreak of ethnic conflicts and their stimulating. The work considers the role of young people as a tool in the political struggle, the reasons for their sensitivity to the ideas of nationalism due to the lack of social experience or the impact of purposeful influence. It summarizes the examples the youth resource use in the process of unleashing, the so-called "color revolutions" and ethnic conflicts related to them, in countries such as Yugoslavia, Georgia, Kyrgyzstan, Ukraine, Moldova. The article does a comparative analysis of successful and unsuccessful revolutionary projects in Armenia, Belarus and Russia. Most "activity" in the part of the preparation of this kind of movement is taking place in the post-Soviet space in the states that make up the core of a new interstate union EurAsEC, and preparation of opposition movements include stimulating Russophobia, rewriting of history and etc. The arising threats require an adequate response. Tae paper brings forward the ways of neutralizing the emerging threats; such as reassessment of the role of the youth; participation in the processes of socialization of young generations in state, public, political and social institutions; systematic and long-term work with young people, not limited to the formal framework of educational institutions, which will help to bring up the generation, resistant to viruses of ethno-nationalism

TO THE QUESTION OF RELIABILITY IMPROVEMENT FOR COLLECTING AND STORING HISTORICAL DATA
DescriptionThe article deals with improving the reliability of data collection and storage of historical data. Investigated the reliability of collecting historical information, the technique, allowing on the basis of general logical and probabilistic methods to identify the most important elements to increase the reliability of which will sig-nificantly increase the reliability of the whole system

CONSTRUCTING A MATHEMATICAL MODEL OF PRICING FOR REAL ESTATE IN KRASNODAR
DescriptionThis study proposes a method of determining the cost of 1 sq. m. apartment on the example of Krasnodar, which is especially important in connection with the necessity of reliable and valid assessment of the property value in a modern market economy. We have performed an analysis of data on apartments in Krasnodar from the site of the Regional Energy Commission - prices and tariffs department of the Krasnodar region. We have also had an exploratory analysis of available data on the subject of emissions and insignificant data (by constructing line graphs and scatter plots); we have also checked for possible dependencies between observations and between variables (built correlation matrix). We have selected variables is linear, the regression model for the variable "cost of 1 sq. m the total area, ths. rub. "(multiple regression). Using regression analysis as a method of mathematical statistics we have revealed a form of analytical dependence of the result of the predictor variables and the degree of this dependence
