Abstract. This article investigated the hypothesis of efficient market (Effective Market Hypothesis, EMH), fractal market hypothesis (Fractal Market Hypothesis, FMH), based on the work of Turner and Turner Weigela, Weigel).
Keywords: stock market, market efficiency, profit.
Summary. The paper deals with a problem with initial conditions for a beam equation with embedded ends. The problem was solved in two ways: as a sum of the Fourier series in the system of eigenfunctions of a one-dimensional spectral problem, and using finite-difference approximations, a numerical solution was obtained. The quantitative coincidence of the results of numerical and analytical calculations of beam deformation is obtained.
Key words: oscillations of a beam, the Euler equation, the initial-boundary conditions.
Abstract: This article discusses the impact of electromagnetic radiation on the human body.
Key words: Cell phone, electromagnetic radiation.
Summary. Investigation of the influence of the properties of infrared rays on a person, the use of infrared radiation for treatment.
Key words: Infrared rays, wide spectrum, photophobia.
Summary: The acid-catalyzed interaction of olefins with aldehydes has been studied as one of the main methods for the preparation of substituted 1,3-dioxanes. The main methods of obtaining both thermal heating and microwave irradiation are considered. It is found that during the Prince reaction under microwave heating conditions, the reaction time is significantly shortened, but the composition of the products does not change.
Key words: 1,3-dioxanes, olefins, aldehydes, acid catalysis, microwave radiation.
Abstract: Substituted cyclopropanes, is one of the Central places in modern organic chemistry, since these compounds and their derivatives have valuable properties and are widely used in various fields of science and technology. The paper describes methods of obtaining substituted cyclopropanes, as well as different ways of their transformation.
Key words: gem.-dihalogentcyclopropanes, cyclopropanation, dihalogencarbenes.
Abstract: Consideration of the concept of a marriage contract, the shape of his detention and order of registration of the marriage contract.
Keywords: prenuptial agreement, marriage, conclusion.
Abstract: This article discusses methods that can be used to identify and determine the content of iron (III) ions in liquids.
Key words: The iron ions (III), determining the method of photometric method, gravimetric method.
Abstract: This article discusses the place and role of project Baby Box in modern society. And positive and negative aspects of this project.
Key words: Newborn baby, Baby Box, a box of life.
Summary. In work the analysis of a risk degree of bankruptcy of Gazprombank Open joint stock company is provided by the method based on use of the device of the theory of fuzzy logic. This method allows to consider quantitative and qualitative indexes which can be both normalized, and not normalized; to consider the level of acceptable risk for the organization and its feature; to beforehand distinguish a possibility of approach of risk of bankruptcy. Using annual accounting records of bank input parameters for carrying out this analysis were chosen. On the basis of the carried-out analysis conclusions are drawn on a financial condition of bank and on its risk degree of bankruptcy.
Keywords. Fuzzy logic, indicator, bankruptcy, risk degree.
Summary: In this paper it is shown that under specified conditions on the initial data a certain infinite coupled system of ordinary differential equations has a solution satisfying an auxiliary convergence condition. The infinite system discussed is essentially the Galerkin expansion of the solution to a given quasi-linear e equation. The results obtained suffice to prove the existence of a solution to this equation of oscillations of a beam.
Keywords: quasi-linear wave equation, method of energy inequalities, equation of oscillations of a beam.
Summary. In this paper we consider the Tricomi problem in a mixed domain for the Chaplygin equation. Frankl was first which showed that the problem of the expiry of a supersonic jet from a vessel with plane walls (inside subsonic speed of the vessel) in the hodograph plane is reduced to the Tricomi problem for Chaplygin equation. In the method of auxiliary functions we received a new theorem of uniqueness of the solution of this problem with the Frankl condition in a new domain, without any restrictions, except the smoothness on the elliptical part of the border domain.
Keywords: method of auxiliary functions, Chaplygin equation of the Tricomi problem, an equation of mixed type.
Summary: In work results of the analysis of risk of bankruptcy of JSC Atomenergoprom are presented. Calculations of degree of risk are given by classical methods: R. Taffler and G. Tishou, G. V. Davydova and A. Yu. Belikov, and also the method based on the theory of fuzzy logic, offered by A. O. Nedosekin. On the basis of these methods the program complex which results and opportunities are presented in this work has been developed.
Keywords: analysis, bankruptcy, risk, model, program complex.
