DYNAMICS OF QUARKS IN THE BARYON METRIC AND THE STRUCTURE OF NUCLEI

abstract 0851301049 issue 85 pp. 624 – 637 28.01.2013 ru 1933
In this paper we consider a system of Dirac equations describing the dynamics of quarks in hadrons metric. The magnetic moment and the energy of the nucleons in the case of deuterium nuclei calculated.

RENEWAL DEPENDENCE METHOD OF LEAST SQUARES BASED NONPARAMETRIC MODEL WITH PERIODIC COMPONENT

abstract 0911307013 issue 91 pp. 192 – 221 30.09.2013 ru 1944
We consider the nonparametric problem of reneval dependence, which is described by the sum of a linear trend and periodic function with a known period. We obtain the asymptotic distribution of the parameter estimates and the trend component. The methods of estimating the periodic component and designing in-terval forecast. In the model of the points of observa-tion, natural for applications, justified by the condi-tions of use. In particular, we prove an asymptotically unbiased estimate of the coefficient of the linear term

EMERGENCE PARAMETER OF CLASSICAL AND QUANTUM STATISTICAL SYSTEMS

abstract 0901306014 issue 90 pp. 215 – 236 30.06.2013 ru 1951
In this article we give a generalization of Hartley's model for the measure of information. We propose a rate of emergence, which is applicable to systems obeying classical or quantum statistics. Quantum sys-tems that obey Fermi-Dirac statistics and Bose-Einstein condensate, as well as classical systems obey-ing the Maxwell-Boltzmann statistics have been con-sidered. We found that the emergence parameter of quantum and classical systems differ as well as the emergence parameter of quantum systems of fermions and bosons. Consequently, the emergence parameter might be used to distinguish the classical system and quantum system, as well as quantum system of fermions and the quantum system of bosons

METHOD OF COGNITIVE CLUSTERIZATION OR CLUSTERIZATION ON THE BASIS OF KNOWLEDGE (Clusterization in system-cognitive analysis and intellectual system "Eidos")

abstract 0711107040 issue 71 pp. 532 – 579 30.09.2011 ru 1994
In this article, on a small and evident numerical example, methodological aspects of a process engineering of detection of knowledge from the trial-and-error data explicitly are considered, representation of knowledge and its usage for problem solving of forecasting, decision making and data domain examination in system-cognitive analysis (SC-analysis) and its programmatic toolkit - intellectual "Eidos" system are shown

MODERN VIEW ON THE SPACE-TIME CONTINUUM

abstract 0891305074 issue 89 pp. 1083 – 1108 29.05.2013 ru 2000
In the article, the goal is a new way to consider some of the processes and phenomena occurring in the Universe and the world around us, to try and answer the question – what is actually a time? To give a contemporary, according to the author, the conceptual apparatus of the categories of space and time. Another goal of the work is to give hypotheses for further developments in the study of the laws of dialectics through existing-relational relations of space objects

REPRESENTATION OF THE SOLUTIONS OF THE NAVIER-STOKES IN GENERAL RELATIVITY

abstract 0981404111 issue 98 pp. 1582 – 1603 30.04.2014 ru 2019
In this paper, we investigated solutions of the Navier-Stokes equations associated with the solutions of Einstein's equations for empty space. There exists a metric in which the Navier-Stokes equations are integrated exactly. We demonstrate that the solution of the Navier-Stokes equations of general form consistent metrics describing in general relativity space with nonzero curvature

CONSTRUCTING THE APPROXIMATE SOLU-TION OF THE TWO-DIMENSIONAL PROBLEM FOR THE EQUATION OF DIFFUSION WITH DEPENDING ON CONCENTRATION COEFFI-CIENTS AND SOURCE FUNCTION

abstract 0601006008 issue 60 pp. 123 – 132 29.06.2010 ru 2020
In the article with the help of a technique, based on discretization initial problem of time variable and the method of basic potentials, is constructed the approximate solution of the second two-dimensional problem for the equation of diffusion with depending on concentration coefficients and source function. The general view of the approximate solution of this problem is reduced. On concrete example convergence of the approximate solution of the problem to the exact is shown

PARAMETRIC TRINOMIALS WITH ALTERNATING GALOIS GROUPS

abstract 0761202071 issue 76 pp. 888 – 897 29.02.2012 ru 2020
In this article, we construct polynomials of third, fourth and fifth degrees with Galois groups as and respectively. In addition, we give examples of polynomials different degrees with Galois groups isomorphic transitive subgroup of group , but calculations with help Maple show that Galois groups of this polynomials is . Also Polynomials with as Galois groups are shown
