MAIN PRINCIPLES OF FORMATION YOUTH MEDIUM UNDER THE INFLUENCE OF THE INSTITUTIONAL SPHERE

abstract 1171603065 issue 117 pp. 1015 – 1031 31.03.2016 ru 1100
The article focuses on how to define the notion of youth as it is considered today, and is aimed to reveal the main social functions in this category, such as educational, professional, cultural, and others, depending on particular historical conditions. A high-demand model of focusing young people's attention on numerous tasks and contemporary challenges the modern society faces is described within the context of the youth leadership concept. This results in working out some strategic programmes and training courses. The peculiarities of the youth labor market give the opportunity to integrate into the market economy and form young people's attitude to labor. The crucial point is to figure it out how the modern system of youth involvement can be correlated with some structural components that determine common competitive features and preferences of the young generation. A resource-balanced approach to organizing quality labor and social activity of the young generation is presented in the article

HOW TO ESTIMATE THE ACCURACY OF DETERMINING THE COORDINATES IN THE APPROACH OF HANSEN

abstract 1171603010 issue 117 pp. 192 – 203 31.03.2016 ru 1107
Recently, there have been satellite-based methods widely used to determine the coordinates of points, which allow, without mutual visibility between points, to pursue their coordinates. However, in some cases, for example in forests, in urban buildings the application of these methods becomes a problem and it is easier to apply traditional methods. The article describes the case of using the method of calculation of coordinates for "the approach of Hansen" and held to evaluate the accuracy of determining the coordinates of the points. Some studies provide only recommendation guidelines that the most accurate results are obtained when the shape of the building is shaped similar to a square. In our case, on the basis of obtained formulae we had an analysis of the influence of the length of the corresponding base, and its distance from the source side on the accuracy of determination of coordinates of the original points. The conclusion is that the accuracy of determination of coordinates of required points depends on the ratio of the length of the original basis and the baseline. The optimal can be considered the distance equal to 0.3-0.6 of the length of the baseline. The holding data in the study can successfully be used for the drafting of geodetic reference polygonometries moves and thickening of networks

TO THE QUESTION OF SOLVING THE PROBLEM OF TWO GEODETIC REFERENCE POINTS USING TWO SOURCES

abstract 1171603043 issue 117 pp. 676 – 683 31.03.2016 ru 698
The article examines an important matter of topical problems of the thickening of planned justification from the starting points, for which we have known or predetermined locations using satellite-surveying instruments. The authors present a method of solving the problem of two geodetic reference points using two sources (the approach of the Hansen) by determining the true adjoining corners and converting the problem to the solution of direct angular notches. We have also given a numerical example of the solution and the estimated accuracy of the obtained coordinates of the points P and Q using found valid adjoining corners and edge lengths of the resulting triangles

HOW TO SOLVE THE TASK OF CLASSIFICATION OF TYPES OF RIFLE AMMUNITION USING THE METHOD OF ASCANALYSIS

abstract 1181604001 issue 118 pp. 1 – 40 29.04.2016 ru 748
In criminology, there are actual problems of determining the type (machine gun, rifle, large caliber, pistol) and a particular model of small rifle for its ammunition, in particular, discovered in the use of weapons. The article proposes a solution to this problem with the use of a new innovative method of artificial intelligence: automated system-cognitive analysis (ASCanalysis) and its programmatic toolkit – a universal cognitive analytical system called "Eidos". In the system of "Eidos", we have implemented a software interface that provides input to the system images, and the identification of their external contours on the basis of luminance and color contrast. Typing by multiparameter contour images of specific ammunition, we create and verify the system-cognitive model, with the use of which (if the model is sufficiently reliable), we can solve problems of system identification, classification, study of the simulated object by studying its model and others. For these tasks we perform the following steps: 1) enter the images of ammunitions into the system of "Eidos" and create mathematical models of their contours; 2) synthesis and verification of models of the generalized images of ammunition for types of weapons based on the contour images of specific munitions (multivariate typology); 3) quantification of the similarities-differences of the specific ammunition with generalized images of ammunition of various types and models of small rifle (system identification); 4) quantification of the similarities-differences of the types of munitions, i.e. cluster-constructive analysis

PROFESSIONAL STANDARDS, INFORMATION AND COMMUNICATION TECHNOLOGIES AND MANAGEMENT IN AEROSPACE INDUSTRY

abstract 1181604016 issue 118 pp. 305 – 332 29.04.2016 ru 761
We should have trained staff to implement innovative strategies. Therefore, it is natural, that a lot of attention is paid to the staffing of the management processes of innovative activity at the enterprises of the rocket and space industry (RCP). Training and human resources management in accordance with current legislation should be based on professional standards. The content of professional standards should reflect the results of forecasting scientific and technical progress in the field, for example, in the RCP. It is necessary to forecast trends in the use of information and communication technologies in solving management problems in the socio-economic sphere in order to reflect these developments in professional standards. The approach to solving this problem is the subject of this article. What should the professional standard be like in the RCP? The main problem lies in the fact that although the standard is to be enacted in the near future, its actual impact on the industry will start in 5 - 10 years and will continue for at least another 10 years, ie, until the 2030s. Professional standards should come from "Education through Science" concept, ie, knowledge, skills, competences, provided by a professional standard, should be based on modern scientific achievements. For example, mathematical methods of research should be based on a new paradigm in the area of knowledge and statistical data analysis methods must meet high statistical techniques. For the development of professional standards in the field of the RCP it is necessary to predict the characteristics of the qualification (level of knowledge, skills and experience) required the employee to carry out professional activities in the RCP in 2020 - 2030. Modern information and communication technologies are creating a fundamentally new situation in the organization of the economy. We have an ability to manage the work of organizational units, scattered throughout the world, from a single center. The requirement of presence in the workplace is mainly a relic of the past. We have a lot of advantages in a remote work

abstract 1181604047 issue 118 pp. 805 – 816 29.04.2016 ru 907
In this article, we discuss various issues related to the formulas approximating the distribution function of prime numbers pi(x). This question has occupied many scholars, but the exact function is well approximated function pi(x) over the number of positive integers not. Based on certain hypotheses, we present a new function s(x) is very well approximated pi(x). The above article hypotheses are so important that their numerical validation and refinement for the lengths of the segments more in 1014 - one of the main areas related to the problem of approximation of the function pi(x) throughout the series of natural numbers. After analyzing the behaviors and constructs many functions, we are building the basis of the function s(x), which is well approximates the function pi(x) throughout the series of natural numbers. We also present a table of values for x, less or equal 1022 for the difference of s(x) - pi(x)

THEORY OF PHYSICAL CONSTANTS AND SUPERGRAVITY IN 112D

abstract 1181604078 issue 118 pp. 1223 – 1245 29.04.2016 ru 408
In this article we discuss a version of the metric theory of the fundamental interactions in which it is assumed that the physical constants due to the presence of extra dimensions of space-time. The estimation of the number of physical constants based on the theory of supergravity in 112D is that the minimum number of constants is equal to 222, and the maximum number - 1404928. At present, the number of parameters that characterize the elementary particles, isotopes and chemical elements is about 150920. This number is 9.3 less than the maximum possible number of parameters that indicate still great potential of modern science. Functions describing the area and volume of a unit hypersphere, embedded in a Riemannian space of arbitrary dimension, were used to find the fundamental physical constants. A satisfactory agreement with a relative error of 0.03% calculated and experimental values of the fine structure constant found out. For the ratio of the average mass of a nucleon to the electron mass is obtained coincidence with the experimental value with an accuracy of 0.002%. The proposed theory of physical constants different from that Bartini theory that established the optimal dimension of the space is a hypersphere 5 and 7, rather than 6 as in Bartini theory. The problems of the compactification of extra dimensions in describing the motion in fourdimensional space-time are discussed

A NUMERICAL ALGORITHM IN THE PROBLEM OF SELF-ORGANIZATION OF LABOR RESOURCES

abstract 1181604086 issue 118 pp. 1333 – 1349 29.04.2016 ru 651
In this article, there is a numerical method of solving the problem of self-organization of the labor resources. The problem deals with finding probabilities of hiring and the layoffs of specialists from the sectors of the labor market. A mathematical model of labor resources dynamics is used to solve this problem. The initial problem is incorrect, because number of equations of the descriptive system is less than number of unknown variables. A special algorithm is designed for guaranteed finding the normal solution in finite number of iterations. The algorithm is separated into two key stages. Initially, unconditional normal solution of the problem is found by applying the modified method of Gauss for underdetermined systems. Later, this solution is projected in the subspace of permissible values. After that, the normal solution of the problem with consideration of non-negativity of the desired values is being found by using the gradient projection method. The proposed algorithm has been successfully used to develop application in programming environment C++. This application is focused on solving of the problem of selforganization of the labor resources. Comparative analysis of speed of the application and add-ins MS Excel "Solver" showed that the same problem is solved much faster in the application designed by the author than in a table processor MS Excel when using the add-in "Solver". This demonstrates the high efficiency of the proposed method

PHYSICAL MECHANISMS OF TURBULENT VISCOSITY AND SIMULATION OF TURBULENCE ON THE NAVIER-STOKES EQUATIONS

abstract 1181604096 issue 118 pp. 1469 – 1487 29.04.2016 ru 357
The article deals with the solution of the NavierStokes equations describing turbulent flows over rough surfaces. It is known, that there is a mechanism of turbulent mixing in natural systems, leading to an increase in the viscosity of the continuous medium. In this regard, we suggest methods of regularization of the Navier-Stokes equations, similar to the natural mechanisms of mixing. It is shown, that in threedimensional flows over a rough surface turbulent viscosity increases proportionally to the square of the distance from the wall. The models of the flow, taking into account the properties of the turbulent environment are considered. A modification of the continuity equation taking into account the limiting magnitude of pressure fluctuations is proposed. It is shown, that due to the pressure pulsation, the incompressibility condition may be violated even for flows with low Mach numbers. Modification of the continuity equation taking into account turbulent fluctuations leads to a system of nonlinear equations of parabolic type. Modification of continuity equation in the system of Navier-Stokes by the introduction of turbulent viscosity allows the regularization of the Navier-Stokes equations to solve the problems with rapidly changing dynamic parameters. The main result of which is obtained by numerical simulation of the modified system of equations is the stability of the numerical algorithm at a large Reynolds number, which can be explained, first, a system of parabolic type, and a large quantity of turbulent viscosity. A numerical model of flow around plates with the rapid change in angle of attack has been verified. We have discovered the type of instability of the turbulent boundary layer associated with the rapid changes in dynamic parameters. It is shown, that the fluctuations of the boundary layer to cause generation of sound at a frequency of 100 Hz to 1 kHz
