Model of a photon

abstract 1111507037 issue 111 pp. 657 – 679 30.09.2015 ru 1145
The article examines the historical aspect of the appearance of the concept of the photon, which was introduced through the works of Planck, Einstein, Compton, Lewis. It is noted that the photon has both corpuscular characteristics (momentum, mass, energy) and wave (frequency, wavelength), which are interconnected. Thus, the photon has dual properties – of a particle and a wave. The article deals with the analysis described in the literature of the photon model proposed by S.M. Polyakov and O.S. Polyakova, F.M. Konarevym-Krauzerom, V.G.Kozlovym and S.I. Chervyakov, as well as with their advantages and disadvantages. A version of the model in the form of a photon of two identical but oppositely charged halfmass, which simultaneously perform translational, rotational and vibrational motion was suggested. We have shown derivation of the amplitude of vibration of the two half-mass photon connected with simple relation with wavelength, described with this photon. On this basis, it is concluded that the state of a photon is characterized by a rotational movement of its oppositely charged half-stuff, which radius (r) is the amplitude of the oscillation process of each of the half-mass, and described by oppositely charged half-mass circumference length S in expanded form in a result of the progressive movement is the length wave l. This work displays the wave equation describing the motion of photons in the form of a standing wave which is a complete analog-independent Schrödinger equation for the motion of an electron in a hydrogen atom

METRIZATION OF MEASURING SCALES OF DIFFERENT TYPES AND JOINT COMPARABLE QUANTITATIVE PROCESSING OF HETEROGENEOUS FACTORS IN SYSTEM-COGNITIVE ANALYSIS AND THE EIDOS SYSTEM

abstract 0921308058 issue 92 pp. 860 – 884 31.10.2013 ru 1751
The 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

METRIC OF VIRTUAL WORLDS

abstract 0931309109 issue 93 pp. 1566 – 1586 30.11.2013 ru 1671
We investigate the hypothesis of a plurality of parallel and virtual worlds. It is assumed that sentient beings in each virtual world reach a stage of development that can create a virtual world to simulate the history of their own development. In this case, the virtual worlds are nested within each other, which put a severe restriction on the possible geometry of space-time. Discussed the draft geometry virtual worlds consistently displayed from one world to another. It is shown that in this case, the metric 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

METRIC OF ACCELERATING AND ROTATING REFERENCE SYSTEMS IN GENERAL RELATIVITY

abstract 1071503112 issue 107 pp. 1722 – 1744 31.03.2015 ru 931
Metric describing the accelerated and rotating reference system in general relativity in the case of an arbitrary dependence of acceleration and angular velocity on time has been proposed. It is established that the curvature tensor in such metrics is zero, which corresponds to movement in the flat spaces. It is shown that the motion of test bodies in the metric accelerated and rotating reference system in general relativity is similarly to the classical motion in non-inertial reference frame. Consequently, there exist a metric in general relativity, in which the Coriolis theorem and classic velocity-addition formula are true. This means that classical mechanics is accurate rather than approximate model in general relativity. A theory of potential in non-inertial reference systems in general relativity is considered. The numerical model of wave propagation in non-inertial reference frames in the case when potential depending of one, two and three spatial dimensions has been developed. It is shown in numerical experiment that the acceleration of the reference system leads to retardation effects, as well as to a violation of the symmetry of the wave front, indicating that there is local change of wave speed

METHODS OF REDUCING SPACE DIMENSION OF STATISTICAL DATA

abstract 1191605005 issue 119 pp. 92 – 107 31.05.2016 ru 610
One of the "points of growth" of applied statistics is methods of reducing the dimension of statistical data. They are increasingly used in the analysis of data in specific applied research, such as sociology. We investigate the most promising methods to reduce the dimensionality. The principal components are one of the most commonly used methods to reduce the dimensionality. For visual analysis of data are often used the projections of original vectors on the plane of the first two principal components. Usually the data structure is clearly visible, highlighted compact clusters of objects and separately allocated vectors. The principal components are one method of factor analysis. The new idea of factor analysis in comparison with the method of principal components is that, based on loads, the factors breaks up into groups. In one group of factors, new factor is combined with a similar impact on the elements of the new basis. Then each group is recommended to leave one representative. Sometimes, instead of the choice of representative by calculation, a new factor that is central to the group in question. Reduced dimension occurs during the transition to the system factors, which are representatives of groups. Other factors are discarded. On the use of distance (proximity measures, indicators of differences) between features and extensive class are based methods of multidimensional scaling. The basic idea of this class of methods is to present each object as point of the geometric space (usually of dimension 1, 2, or 3) whose coordinates are the values of the hidden (latent) factors which combine to adequately describe the object. As an example of the application of probabilistic and statistical modeling and the results of statistics of non-numeric data, we justify the consistency of estimators of the dimension of the data in multidimensional scaling, which are proposed previously by Kruskal from heuristic considerations. We have considered a number of consistent estimations of dimension of models (in regression analysis and in theory of classification). We also give some information about the algorithms for reduce the dimensionality in the automated system-cognitive analysis

METHODOLOGY OF CONTROL PROCESSES MODELING IN SOCIO-ECONOMIC SYSTEMS

abstract 1011407011 issue 101 pp. 166 – 196 30.09.2014 ru 1596
The article introduces the basic concepts of control theory. It has also noted the multicriteriality of real control problems. After reviewing the basic concepts of the theory of modeling we have analyzed postwar history and current status of mathematical modeling of control processes. We have also discussed the modeling methodology. As an example of a real model of the management process we have considered a model of allocation of time between the acquisition of knowledge and development of skills

MECHANISM OF FORMATION AND PROPAGATION OF WAVES IN THE ELECTROMAGNETIC ENVIRONMENT

abstract 1001406061 issue 100 pp. 931 – 948 30.06.2014 ru 1782
We 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
