To study complex sonar systems, the method of decomposition was suggested. The peculiarities of the method applied to the sonar systems were considered. A four-level hierarchy of decomposition subsystems is proposed. A scheme of the first level of semantic decomposition was presented. Controlled modules allowed to build adaptive systems were described.

Keywords: decomposition, hydro speaker systems, hierarchy of subsystems

The most important aspect of the development of the regional economy is shaping prospects for determining the stability of the economy, allowing optimum combination of goals, means and results of its operations for the protection of the natural potential in urban environments. To achieve these goals requires the development of methodological principles of ecological and socio-economic policy, which aims to realize the sustainable development of the region. Selection of methods for the study of natural resource potential of a particular area is important for assessment activities, the establishment of indicators and assessment criteria, selection of a systematic approach for the formation of sound environmental activities like inter-settlement spaces and urban conditions

The state of the atmospheric air in such industrial cities of the Rostov region, as Belaya Kalitva, Donetsk, Kamensk-Shakhtinsky over the last 10 years (2003-2012). Identified main pollution sources and priority pollutants. Analysis of the concentrations of pollutants in areas of concentration of industrial enterprises, on highways and in dwelling zones. It is established that industrial cities are specific «geochemical provinces», in which abnormally elevated concentrations of many chemical elements. On the background of the decrease of the role of industrial enterprises in the air pollution increases the role of motor transport

This paper describes application of different criteria for estimating parameters of traffic simulation. For comparison following methods were used: statistical methods for comparison of a flow and speed in control points of a network - analysis of variance (ANOVA), Theil's U-statistics; relationships between flow, density and speed; relationships between trip time and stop time with using two-fluid models of traffic flow. For this aim we also used concept of meta-model. In order to implement this method we need on the first step to create separately relationship between traffic flow parameters for observation and simulation data and then to estimate combined model. The paper included results of calculation  

Keywords: validation, traffic, simulation, flow, speed
