ANALYSIS OF THE PROCESSES CAUSED THE MAGNETIC FIELD INFLUENCE ON A STRUCTURE AND PROPERTIES OF WATER
01.00.00 Physical-mathematical sciences
DescriptionThe scientific publications review about a magnetic field influence on cluster sizes and their concentration was carried out. These structural changes are attended by the water system physicochemical properties changes. For example, the surface tension coefficient changes. It is shown, that the conductivity and the dielectric constant of water change in a weak magnetic field. It is provided, that characteristics of water activated by a magnetic field can save in a significant time

MECHANISM OF FORMATION AND PROPAGATION OF WAVES IN THE ELECTROMAGNETIC ENVIRONMENT
01.00.00 Physical-mathematical sciences
DescriptionWe discuss the question of the essence of formation and propagation of waves in the electromagnetic environment. We have questioned the reliability of its description by J. Maxwell in the form of alternating electric and magnetic fields. The article justifies the formation of an electromagnetic wave in the form of a wave compression-decompression surrounding electromagnetic photon field flux of photons of different frequencies emitted by different sources or antenna

ABOUT THE DEVELOPMENT OF THE STATISTICS OF NONNUMERICAL OBJECTS
01.00.00 Physical-mathematical sciences
DescriptionAbout thirty-five years ago, the statistics of non-numerical objects was highlighted as an independent field of mathematical statistics. This article analyzes the basic ideas in this area, and relevant publications on the background of the development of applied statistics, and in connection with the system fuzzy interval mathematics

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

AVERAGE VALUES AND RULES OF LARGE NUMBERS IN THE SPACES OF ARBITRARY ORIGIN
01.00.00 Physical-mathematical sciences
DescriptionThe new results of the sample average values in different spaces and rules of large numbers for them are given in the article. We also introduced the weighted average values of type I corresponding to the sample, and type II, corresponding to the set of order statistics. The evolution of ideas about the Kemeny distance and the Kemeny median is traced. The modified Kemeny median, convenient for computation and avoiding the effect of the "center of the bagel hole" is proposed. As a generalization of the Kemeny median, we introduced and studied the empirical and theoretical values in the spaces of arbitrary origin. For them, we proved the rules of large numbers

01.00.00 Physical-mathematical sciences
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
