The completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows over rough surface
Numerical solutions of equations system of turbulent transport of admixtures in a surface layer of the atmosphere and for a large scale have been studied
The model of continuous transition from the laminar flow to the turbulent flow is proposed and the theory of the spectral density of turbulent pulsation is given
It has been experimentally proven that thermal radiation of optically transparent solid objects forms from the entire heated volume within the spectral frequency that is allowed to pass through
The analysis of the lyric cycle «The Theme with Variations» by B. L. Pasternak has been reviewed in this paper. Results have been given of the study of the semantic fields of the poetic texts. The data obtained provide an exhaustive interpretation of the structure of the ensemble
In the article process of interaction of real sector of economy and the share market on an example of Russia is considered. Sensitivity of the share market to the information factor in a stable and crisis phase of development is investigated; comparison of reaction to the information of the Russian and American market to use of dynamics of indexes of RTS and Dow Jones is carried out. The received results are based on methods of the correlation and graphic analysis
The basic items of modeling of intellectual techniques improvement are presented in the article. These are done in a form of processes described by mnemonic schemes based on consideration both of “market players” preferences and of programming methods of their fillings-up in accordance with the level of a user’s engineering-managing competence which is required
Extraction of the DNA from leaves of genus Vitis is a very difficult task, as a grape has a lot of elements, which make difficult to use it in the genetic manipulation. In that article used the methods of extraction of the DNA with silica (SiO2) particles as the absorbent material for getting better quality DNA
The article is devoted to the use of methods of cluster analysis, such as multivariate statistical, indistinct and neuronet, for an estimation of financial and economic condition of middle and small enterprises of building branch of Krasnodar region, and also to revealing of the reasons and laws of occurrence and development of crisis at these enterprises
The article provides an overview of the basic rating methodologies, describes an algorithm of the own methodology for estimation the creditworthiness and investment attractiveness of the agricultural enterprises of Krasnodar region, using modern mathematical models. The rating of 30 agricultural enterprises of various patterns of ownership and scale is presented. The rating of 30 agricultural enterprises of various patterns of ownership and scale is presented
