MODELS OF NEURONET INFLATION IN RUSSIA
01.00.00 Physical-mathematical sciences
DescriptionThe article’s conclusion is that for adequate and effective inflation modeling in Russia by means of modern neuronet technologies it is necessary to consider tendencies of economic development. For training and forecast, it is necessary to use only those periods of time within the limits of which identical economic tendencies work. The article uses modern tool means, such as neuronet, which is offered to technology, for approximation and forecasting of rates of inflation

ISOTOPIC REDISTRIBUTION IN PRODUCTS OF PLASMA PROCESSES FOR HIGH FREQUENCY DISCHARGES
01.00.00 Physical-mathematical sciences
DescriptionResearches in plasma methods for isotopes separation and analyze of the results were done. Results show high values of separation coefficient for intermediate products during the last years. It is shown by us, that these factors will be considerably reduced in the subsequent plasma processes and a way of freezing of high value of factor of division of isotopes

DescriptionIn the article with the help of a technique, based on discretization initial problem of time variable and the method of basic potentials, is constructed the approximate solution of the second two-dimensional problem for the equation of diffusion with depending on concentration coefficients and source function. The general view of the approximate solution of this problem is reduced. On concrete example convergence of the approximate solution of the problem to the exact is shown

THEORY OF TURBULENCE AND SIMULATION OF TURBULENT TRANSPORT IN THE ATMOSPHERE PART 4
01.00.00 Physical-mathematical sciences
DescriptionThe 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
