The article describes the experience of using wind power stations in Russia, presents the choice and rationale for the use of alternative sources of electricity for the Omsk region. The design allows to increase the speed of the air flow in the field of energy extraction by 1.45 times, which allows to obtain three times more energy than a wind power plant with a similar area of wind wheel sweeping. The technical and economic calculation and calculation of return on capital investments for the proposed solution are presented. [ABSTRACT FROM AUTHOR]

The technique of segmenting data samples in order to improve the quality indicators of classifying algorithms is considered. It takes into account the factors that affect the change in the ranges of values of the target variables. Identifying impacts on current and anticipated situations makes it possible to segment data samples. As a result, the ranges of the studied variables and outliers are reduced, and noisy data are removed. The conducted experiment with the use of a divided sample is described. The evaluation results for each classifier on the total sample and on the segments are obtained. [ABSTRACT FROM AUTHOR]
