This article gives a survey of the issue of the thermal dynamics identification of the sensor network based systems, such as buildings. Given problems: weaknesses of the modern sensor network based intelligence systems, that mostly limits their potential and increasing calculation costs are overviewed. Article describes a novel approach for intelligence control systems design based on sensor networks, using methods of fuzzy modeling. The key future of the given approach is in saving of high efficiency characteristics of modeling in case of sensor network nodes amount decreasing. As an example of the approach usage there are presented results of experimental test space thermal dynamics simulation model analyzing. The advantages of the developed solution to other existing commercial solutions are shown. The methodology was tested and its efficiency is shown.

Carbothermal synthesis method on substrates of a-Al2O3 thin film with sublayers ZnO: Ga, using copper as a catalyst for the arrays obtained by varying the zinc oxide rod morphology. It was established that growth of the rods occurs direction perpendicular to the substrate using a thin (~ 1 nm) layers of the catalyst. With increasing thickness of the catalyst layer to 3 nm rods growth occurs at an angle to the surface of the rod with a mutual orientation in the plane of the substrate surface at angles that are multiples of 60 °. Also, the selectivity demonstrated growth ZnO rods arrays on portions of the substrate coated with the catalyst.
Keywords: zinc oxide, micro - and nanorods carbothermic synthesis method, film sublayer growth catalyst.

Offers intelligent method of assessing the reliability of data (verification), in databases, based on the theory of artificial neural networks. The method consists of three steps: data clustering using the Kohonen network, training radial basic network and its computation using the validation database table rows. To create a radial basis networks and their training Backpropagation developed software tool. The proposed verification method of data can be used in various applications of information systems.
Keywords: database, relational algebra, verification, radial basis neural network training neural networks, Kohonen networks, clustering.

This article discusses a method for calculating the combined diagnostic feature called spectral signature, based on the use of mathematical apparatus Walsh transformations for logic functions and differential logical calculus. We consider a class of devices which can be implemented in the proposed method. A method for determining the spectral signatures for discrete devices differs from the known methods of diagnosis less computational complexity and allows the implementation of a self-test in the operation of devices.
Keywords: spectral testing, signature analysis, technical diagnostics, information and control systems.

Researches based on results of the questioning, conducted in late 2010 - early 2011 among the students of Rostov-on-Don (RSCU), Vladikavkaz (GTU) and Grozny (GGNI). Results were interviewed about 500 people (58.4% - 40.6% of men and - women). 33.3% of respondents represented Rostov-on-Don, 40.4% - the city of Grozny and 26.4% - the city of Vladikavkaz. 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. It is revealed, during the studied period there is a low level of participation of the young people to political processes with the average level of an involvement at Rostov-on-Don. In Grozny there are average and high levels of participation of the young people to political processes in the Republic, and also high level of an emotional involvement. Analysis the block of relative deprivation showed the youth of Rostov-on-Don and Vladikavkaz is more subject to a political tension, the least possible tension in the city of Grozny. It is revealed, at Rostov-on-Don there is a process of political alienation. The students of Vladikavkaz associate an assessment of the level of a political tension with local political order, instead of with Russia as a whole. Shown, in general, the level of relative deprivation at the end of 2011 is average.
Keywords: a political tension, deprivation, group installation in relation to a political order, cognitive component, questionnaire, the descriptive statistics.
The analysis of operating conditions of transport systems shows that constantly increasing needs for freight transportation at existing level of auto mobilization are accompanied by a number of problems. Lack of a route network and information support about traffic conditions for movement of Lorries involves negative influence on social and economic development of the cities and the country as a whole. Owing to growing load of the highways, increasing intensity of freight automobile transportation in the conditions of the modern large cities megalopolises need of planning and regulation of transport streams sharply is felt. For ensuring comfort to participants of traffic and their informing on a condition of a transport network, for decrease in material and financial expenses the control systems of the traffic which have received the name Intellectual Transport Systems were created.

In this paper, a comparative analysis of the shift parameter distribution initial set of calculated analytical method and simulated, obtained by computer simulation using sample data. Error δi shifts between the parameters listed in the table and plotted errors on the scope and volume of the aggregate.
Thus, increasing the volume of the aggregate error is reduced from 30% to 1% at a constant volume sample m = 50.

The paper presents the results of the pilot study of perception of the political order of Rostov-on-Don on the end of 2011. The questioning method was used. In total 499 respondents were interviewed, and captured the age group from 18 years to 65 years. The purpose of questioning - the definition of the emotional component of the group political installation on the classical method of semantic differential Charles Osgood. A comparative analysis was carried out of the averaged semantic level of emotional portraits and making real political order. It is revealed the existing political order in Russia in general and the city of Rostov-on-Don, respondents were almost equally perceived negatively. It is shown the generalized probability perception of an order in Rostov-on-Don and in Russia will change at change of external conditions: at improvement of a situation will slowly increase, at situation deterioration the probability acceptance of an order will quicker decrease, up to zero and negative value.
Keywords: A political tension, semantic differential, factor analysis, the affective component, questioning.
It’s presented the analysis of the cognitive components of the perception of the political order based on the pilot questioning. The questionnaire included a subjective assessment of the following levels the participation in political processes; the emotional involvement into them; discussion of 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 parent’s 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. Evaluation revealed a low level of economic welfare for the average values of - 1.73, the low level of social protection - 1.22. It’s received; the level of relative deprivation on a group in December 2011 is higher than an average, reflecting the political tensions in the latent form.
