The article is devoted to development of effective and adequate mathematical models of an estimation of a financial and economic condition of region and meeting program toolkit with use of multivariate statistical models and fuzzy logic systems
In paper the class of prefractal the trees generated by set of seeds-stars with alternation is defined. The algo-rithm of this class prefractal graphs recognition is proved. It is proved also polynomial character of the offered recognition algorithm
The scientific publications review about the physicochemical properties of pure water and water solutions activated by a microwave radiation was made. The convincing evidences of the water structure changes in the microwave were submitted
The article analyzes the various approaches to the mathematical modeling of financial pyramids. It considered “economically rational subject”, game approach and the approach of Dubovsky. In this article, the mathematical models of the unproblematic approaches examined; we also analyzed their characteristics, including the dependence of the lifetime of the pyramid of accrued interest and the number of clients, the maximum possible profit of the founders of the pyramid, etc. This work analyzes the various options of the campaign, including whether the implicit advertising company, which arises from the spread of the financial company clients and rumors about their income
The dynamics of the state of spin of the radical oxygen-carbon pair are observed. By way of mathematical modeling, optimal conditions for conducting experiments to obtain the maximum meaningful coefficient of division of carbon isotopes was established
Perturbed motion of a pole of the Earth caused by gravitational
action of celestial bodies is explored in the
article
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 for a large scale have
been studied

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. The estimated mean velocity, temperature and impurity concentration profiles as well as the spectral characteristics of the streamwise velocity component are to be shown in a good agreement with the experimental data
Dependence of the Earth polar motion on celestial bodies’ positions is examined on the basis of semantic information models
