INFORMATION SYSTEMS EFFICIENCY IMPROVEMENT WITH INTELLECTUAL TECHNIQUES
DescriptionThe 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

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
