  • Developing of the algorithm of maximum flow of minimum cost finding in a fuzzy dynamic network

    The article considers the problem of maximum flow of minimum cost finding in fuzzy dynamic transportation network. The relevance of the problem is in its wide practical application on the rail, air, sea and other roads in finding of routes of minimum cost. The feature of the problem statement is that fuzzy nature of the network parameters, such as arc capacities and costs is taken into account. It allows us to make decisions more sensitive to environmental changes. The dependence of network parameters from flow departure is also considered, that allows to introduce the notion "dynamic" network as opposed to "stationary-dynamic", examined in the literature. The algorithm for solving the described problem in fuzzy conditions is proposed. To illustrate the algorithm a numerical example is presented.

    Keywords: dynamic network, maximum flow of minimum cost, fuzzy numbers, arc capacity, transit time

    "Examines the relationship of the concepts on the example of post-war reconstruction of post-war reconstruction of the city of Rostov-on-Don.
    In 1945, the Chairman of the Committee on Architecture AG Mordvinov announced seven conditions under which you can create the city.
    In 1945, the development of the urban plan of rebuilding the city of Rostov-on-Don was appointed academician of architecture VN Semenov.
    In 1949. master plan was finalized at the construction site.
    In general, the basic idea of the architect was executed. Among the fifteen cities prone to restore the city of Rostov was restored in all seven conditions put forward by the Chairman and the Committee for Architecture AG Mordvinov, projected architecture academician VN Semenov and given a reality by means of the chief architect of YA Rehbein."

  • Analysis of time series with cig fractal processing

    Briefly discussed the theoretical model of the spectrum of RR intervals and its changes depending on the processes taking place. Made a device for measuring cardiointervalogramms (CIG). Obtained from the renting of data, of varying duration and frequency shall be recorded for further processing. The analysis revealed that the resulting spectrum satisfies the conditions considered in the theoretical model, and can be further analyzed with fractal characteristics. Such an analysis is of great importance in the diagnosis of the patient directly to the duration of the therapeutic procedure for the optimization of both time and intensity exerted influence.

    Keywords: CIG; fractal series; the spectrum of RR intervals

  • Electrochemical titanium oxidation in electrolytes on the basis of glycerin with high water content

    The titanium dioxide synthesized by an electrochemical method is a perspective material for use in solar elements and catalysts of cleaning of water and air environments. Regularities of electrochemical synthesis of titanium dioxide in glycerin dilute solutions (1:1) in the presence of ammonium fluoride at 2-14 V are investigated. Mathematical scheduling of synthesis process according to plans of first order with use of the complete three-factorial experiment is carried out, the adequate regression equations for formation processes of a titanium dioxide in the field of potentials 8-14 V are received. The electron microscopy method proved porosity of synthesizable layers of titanium dioxide. Water content influence in electrolyte on the speed of electrochemical process and potential size influence on titanium dioxide materials yield is established. It is shown that under the chosen electrolysis conditions electrochemical process is accompanied by the considerable chemical disolution of a titanium. Electrochemical processes in water containing glycerin are investigated by a cyclic voltammetry method. It is established that at electrochemical oxidation of Ti in water containing glycerin (1:1) porous TiO2 with a materials yield no more than 25% is formed.

    Keywords: titanium, titanium dioxide, electrochemical oxidation, glycerin, ammonium fluoride, experiment scheduling

  • Adjusting characteristics of the planetary generator of the moment

    In article dependences of resistance are investigated on drove the planetary mechanism from the operating moment on the central wheel. The hypothesis about active and jet components of mechanical resistance is offered in compliance with a method of electromechanical analogies. Results of pilot studies of the adjusting characteristic of the generator of the moment confirming theoretical provisions are presented.

  • Perception of a political order among students of Vladikavkaz in 2012

    Research presented the analysis of the cognitive components of the perception of the political order based on the pilot questioning in Vladikavkaz in 2012. 47 respondents took part in questioning. The questionnaire included a subjective assessment of the following levels the participation in political processes; the emotional involvement into them; discussion of the these processes; economic welfare; social protection; life prospects. In addition, the questionnaire included questions about the degree of religiosity, and also the general questions characterizing the respondent (a sex, age, a nationality, level of parents education). To assess the level of deprivation used the subjective opinion of respondents on the levels of economic welfare and social protection, assessment of prospects in life, and also the degree of involvement in various political processes. Received, the level of involvement of young people in Vladikavkaz in the political processes in society - 1.28, the level of emotional involvement - 1.91. Average consistent level comments political processes in the family - 2.15.  The level of economic well-being and average level of social protection of students: 2.27 and 2.34. Assessment of prospects in life is average - 2.96. It was revealed in 2012, there is a low level of participation in political life with a low level of involvement in the political process. Some parameters of relative deprivation is average, and it is expected that this component will not lead to the formation of political tension.

  • Dynamics of a cognitive component group setting among students of Grozny in relation to a political order (according to 2011 - 2012)

    Researches based on results of the questioning among the students of Grozny (GGNI), conducted in 2011 - 2012. Over the entire study period, 525 people were interviewed. The questionnaire consisted of questions focused at identifying the subjective opinions on own relation of respondents to a political order, and also questions opening level of a group relative deprivation. The received results of a cognitive component were processed by a method of the statistical analysis in software package SPSS. It is revealed, increase the level of relative deprivation among a group of students, which may indicate an increase in the level of political tension. Detected, reducing the level of emotional involvement in the political life of the Republic, which is exacerbated by increased levels of alienation from the political process. In the identification of situations among student of Grozny need to direct efforts local government at ending the fall of the level of emotional involvement, as well as to control the level of relative deprivation with fixing it to reach the middle level.
