Description
In the article we have estimated sorption capacity of sorbents and analyzed the factors influencing it; we have also selected the optimal conditions for the sorption process, depending on the circumstances and nature of the treatment facilities. The possibility of purification of oil-contaminated water from heavy metal ions synthesized inorganic sorbent has been shown

FUZZY SETS THEORY AS THE PART OF PROBABILITY THEORY
01.00.00 Physical-mathematical sciences
DescriptionOne of the key provisions of the system fuzzy interval mathematics - the claim that the theory of fuzzy sets is the part of the theory of random sets, thus, part of the probability theory. The article is devoted to the justification of this statement. Proved number of theorems that show that the fuzzy sets and the results of operations on them can be viewed as the projections of random sets and the results of the corresponding operations on them

PREONS CURRENTS AND WIRELESS POWER TRANSFER
01.00.00 Physical-mathematical sciences
DescriptionIn this article, a model of preons electric currents caused by the motion of preons in the electron shells and nuclear shells is proposed. It is assumed that preons currents may contribute to the conductivity of the material. A closed model of electrodynamics, which describes the diffusion of the vector potential due to the contribution to the conductivity of preons currents, is formulated. An analogy of hydrodynamics and electrodynamics of continuous media with preons currents is considered. A model of the wireless transmission of electricity is proposed

DescriptionThe article considers measuring scales as a tool for creating formal models of real objects and a tool for increasing the degree of formalization of these models to a level sufficient to implement them on computers. It also describes the different types of measuring scales, allowing to create models of varying degrees of formalization; lists the types of transformation valid during the processing of empirical data obtained with scales of different types; develops the task of metriza-tion of the scales, i.e. conversion to the most formalized mind; it proposes 7 ways of metrization of all the types of scales, providing a joint comparable quantitative processing of heterogeneous factors measured in different units of measure due to the conversion of all scales to one universal unit of measurement in which the measurement number of information is selected. All of these methods of metrization have been implemented in the system-cognitive analysis and in the Eidos intellectual system

DescriptionIn this report we have compared an approximation accuracy of distribution function of continuous random variable in a bounded region calculated with Rozenblatt-Parzen method and imaginary sources method. The comparison has been performed with theoretical distribution rule. We have explained the reasonability of using imaginary sources method in case of continuous random variable with single-mode distribution rule
