In the article, popular technical «Stochastic Oscillator» indicator is considered. Various trading strategies based on the indicator are researched; the parameters with statistical advantage are revealed
The problem of drug addiction in the Russian
Federation poses a threat to the national security. For
effective decision-making in the field of drug
prevention and fight against drugs, it is necessary to
assess the drug situation, the state of law enforcement
practices and socio-economic development of the
observed areas. The article describes the method of
complex statistical evaluation of the level of drug
addiction in the Russian Federation. Based on a
systemic approach author distinguishes stages of
multivariate statistical analysis of a priori indicators
characterizing the state of socio-economic,
demographic, biomedical and law enforcement
situation in certain areas of the federal districts of the
Russian Federation. The classification of signs into
factorial indicators groups is proposed. Estimations of
relationships studied statistics and draw conclusions
about the impact on the drug situation of various
factors, including the average for the group, are
presented. Then this paper describes the application of
the factor analysis to construct regression models to
predict the drug situation in the Russian Federation
according to the status of independent indicators and
trends in the integrated development of regions. A
method for evaluating the level of development of the
drug situation in the Russian Federation because of
automatic classification algorithms is proposed and the
principle of its application is proven. The results of the
classification of the federal districts of the Russian
Federation on the level of the drug situation are given
There were conducted the theoretical explanations of standby wind power plant. There was obtained the distribution law of wind speed and its statistical operation factors, equations of the dependence of voltage regression and capacity of wind power plant upon wind speed, confirmed the convergence of theoretical supposition and experimental data
In the article, we have presented the results of the harmonic analysis of pole-switching motor winding for a fan drive. The stator winding at 10/6 allow you to fully utilize the size of the basic six-pole engines, and the stator winding at 8/4 pole differ with simplified switching
The article considers the questions of definition of economic efficiency of the developed method for reuse drainage waters. The size of the economic result with account of ecological factor and cost of building production is defined. The estimation of efficiency of the developed method on following indicators is made: the discounted net profit; the profitableness index; the internal norm of profitableness; time of recovery of outlay
The article discusses various ways to store chronological data. The mathematical models were constructed for each method. As one of the solutions is the method of data of organization partitioning of a particular DBMS
Improvement trends of methodical approaches in complex cereals harvesting in optimal terms with technical support substantiation are considered. Structure and technical equipment are considered as well
It is shown that the combination of the cold equal channel pressing with low-temperature annealing leads to the formation of a sub-microcrystalline ferritic matrix hardened with nanoscale particles of the carbide phase in steel 09G2S. Resulting structure
leads to the achievement of the high-strength state, as well as a significant reduction of the wear intensity of the material
The article considers the problem of creating of wood adhesive joints of high strength, through the use of adhesives, which were subjected to electrical treat-ment. We study the effect on the cohesive and adhe-sive strength of the joints on glues on the wet ability of wood adhesives and adhesive viscosity, exposed to electric field treatment
The article presents the results of the research of the changes in the technical properties of a pine wood after fire damages
