Existing theoretical positions impact of government (regional and municipal) governments on the development of the service sector is expected to maintain an appropriate ratio between the market and state intervention in the economy and the economic life of enterprises and organizations of this sector of the economy of the region. It can be achieved by observing a general principle, the essence of which lies in the presence of competition wherever possible adjustment where necessary.

Cold asfaltobetonny mixes which unlike standard mixes prepare without drying and heating of a mineral component are developed. Advantages of these mixes are that they is better, than standard mixes cooperate with a damp repaired covering and in the course of warehousing don't demand performance of actions for prevention of caking of a mix. Mixes are intended for timely localization of the centers of the destruction appearing on pavings in the early spring and autumn.

Keywords: emergency repair of pavings, hollows and sags, surface-active substances, razzhizhenny bitumen, cold asfaltobetonny mix.

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.

Keywords: intellectual control systems, sensor network, data analyzing, fuzzy modeling, fuzzy classification, membership function.

The problem of restoring gaps in socio-economic data. Used konnektivistskie principles describe multilevel relationships between socio-economic targets for restoring missing data. Proposed fuzzy method of filling gaps in the data socio-economic parameters based on the analysis and formalization in terms of fuzzy logic relationships between the parameters of the same type in other network objects. To justify the effectiveness of an example implementation of the method on data from rural areas of the Volgograd region.

In the present work we have carried out studies of the processes of growth of zinc oxide nanorods by hydrothermal method on silicon substrates. As sublayer catalyst used growth caused by laser deposition of zinc oxide, various thicknesses. Studied selective growth of nanorods on the microstructure of thin-film sub-layers of zinc oxide obtained by laser deposition. The optimal conditions for the synthesis of: the concentration of Zn (NO3) 2 - 0.4 mol / l, hexamethylenetetramine - 0.4 mol / l, the concentration of NH3 · H2O - 0,01 mol / L -0.01, process time 4:00, the process temperature is 80 ° C. Sublayer thickness of zinc oxide, as shown by experiment, the growth of the rods has no noticeable effect. Oriented arrays of nanorods were obtained up to 500 nm and a diameter of 60-150 nm.
Keywords: zinc oxide nanorods and micro-oriented arrays of nanorods, hydrothermal synthesis method, selective growth, thin film underlayer.
