ANALYSIS OF METHODS OF GENERATION OF TIME SERIES WITH LONG-TERM CORRELATION STRUCTURE
01.00.00 Physical-mathematical sciences
DescriptionThis article gives a comparative analysis of six modeling techniques of fractal differential noise, including: direct definition method, the method of Hosking, the method of Davis and Hart's, the circulant embedding method, Paxson method and method of spectral simulation. Furthermore, the algorithms are given for the analysis and the method of estimation of Hurst`s parameter is selected, this method is the main criterion of quality when comparing the above mentioned methods of fractal differential noise

DescriptionArticle is devoted to the numerical analysis of regional problems for system of the equations of Nernst-Plank-Puasson (NPP), to application of these regional problems to modeling and studying of mass transfer in the channel desalting of electro dialysis device. Various mathematical models of the transfer of ions in potential static mode in the form of system of the quasilinear equations with private derivatives are offered. The basic rules of occurrence and development of a spatial charge in the channel desalting of electro dialysis device are revealed

DEVELOPMENT OF MATHEMATICAL MODEL OF PROCESS OF HEATING OF AIR FOR DRYING GRAIN
01.00.00 Physical-mathematical sciences
DescriptionIn the article, the analytical way of working out of mathematical model of process of heating of air for grain drying is shown. It is considered, that the temperature of a wall influences on dynamics of process of heating. Dynamic characteristics of the top internal device are considered. With use of package Mathcad schedules of transitive functions on operating and revolting influence are received. Results of modeling are presented
