COSMOLOGY OF INHOMOGENEOUS ROTATING UNIVERSE AND REALITY SHOW

abstract 0951401028 issue 95 pp. 511 – 540 30.01.2014 ru 1205
On the basis of the solutions of Einstein we have proposed universal metric describing the properties of an inhomogeneous rotating universe. It is shown that in the case of space-time metric of negative curvature, the field equations are hyperbolic, parabolic or elliptic type, depending on the equation of state. An equation for the general state of the species, describing the emergence of matter, as the aggregate state of dark energy proposed

HEEDING OF HETEROGENEITY OF ENVIRONMENT WHEN CALCULATING A MAGNETIC FIELD

abstract 0951401052 issue 95 pp. 925 – 934 30.01.2014 ru 919
The formula for definition of magnitude and direction of secondary sources of a field as surface currents for the registration of heterogeneity of environment is found. We have shown that it is possible to solve non-linear field problems, using the mathematical deduc-tions shown in this article

QUANTUM GRAVITY AND YANG-MILLS THEORY

abstract 0951401070 issue 95 pp. 1203 – 1228 30.01.2014 ru 1080
In this paper, we consider Einstein's theory of gravitation in connection with Yang-Mills theory. The model of the metric satisfying the basic requirements of quantum theory is proposed. The mechanism of generation of baryonic matter of dark energy is discussed

ТНЕ NUMERICAL METHOD OF SOLUTION OF TWO-DIMENSIONAL SINGULAR INTEGRAL EQUATION OF THE FIRST KIND IN THE PROBLEM OF THE FLOW OVER THE THIN PROFILE BY THE STREAM OF COMPRESSIBLE GAS

abstract 0951401073 issue 95 pp. 1268 – 1278 30.01.2014 ru 1447
This work deals with the numerical method of solution of integral equation with the kernel, which has the first order singularities by two variables. The solution is approximated by piecewise linear functions by every variable. The coefficients are determined by the collocation method. The singular integrals of basic functions are calculated exact

INVESTIGATION OF TRANSPORT OF SALT IONS IN THE EXPERIMENTAL ELECTROCHEMICAL CELL WITH ROTATING DISK MEMBRANE

abstract 0941310025 issue 94 pp. 335 – 346 27.12.2013 ru 1260
This work is a continuation of [1], which was devoted to the investigation of the hydrodynamics of the experimental electrochemical cell with rotating disk cation exchange membrane. This article focuses on the transport of salt ions in a closed cell at different initial experimentation with modes of exact current regimes. The main regularities of transport of salt ions and membrane equal accessible surface were set

GENERAL RELATIVITY AND GALACTIC METRICS

abstract 0941310027 issue 94 pp. 359 – 383 27.12.2013 ru 1117
It is shown that the metric of the galaxy should be universal, depending only on the fundamental constants. There are examples of universal metrics obtained in Einstein's theory of gravitation and Yang-Mills theory. The axial-symmetric solutions of Einstein’s equations for a vacuum are applied to explain the rotation of matter in spiral galaxies

THE HIGHER ASYMPTOTIC EXPANSIONS FINDING FOR BOUNDARY VALUE PROBLEM OF THE ZOM MODEL

abstract 0941310035 issue 94 pp. 490 – 506 27.12.2013 ru 1315
In this article authors propose the asymptotic solution of the boundary value problem modeling the transport of salt ions in the cell electrodialysis desalination unit. The domain of the camera desalting broken into two subdomains: electroneutrality and space charge. Subdomains has own asymptotic expansion. The subdomain of the space charge has unique solvability of the current approach used by the solvability condition of the next approximation

BASIC IDEAS OF INTERVAL DATA STATISTICS

abstract 0941310060 issue 94 pp. 868 – 893 27.12.2013 ru 2261
In the article we have considered the basic idea of asymptotic mathematical statistics of interval data, in which the elements of a sample are not the numbers, but the intervals. Algorithms and conclusions of interval data statistics fundamentally different from the classical ones. The results related to the basic concepts of notna and rational sample sizes are listed. Interval data statistics as an integral part of the system of fuzzy interval mathematics is shown

GENERAL RELATIVITY AND METRIC OF LOCAL SUPERCLUSTER

abstract 0941310061 issue 94 pp. 894 – 917 27.12.2013 ru 1124
It is shown that the metric of clusters of galaxies should be universal, depending only on the fundamental constants and compatible with the metric of the universe. There are examples of universal metrics obtained in Einstein's theory of gravitation. On the basis of axisymmetric solutions of Einstein’s equation proposed universal metric describing the properties of galaxies, groups and clusters of galaxies
