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

The state of surface water in such industrial cities of the Rostov region, as Belaya Kalitva, Donetsk, Kamensk-Shakhtinskiy. Identified the main sources of their pollution and priority pollutants. Analysis of the concentrations of pollutants in R. Sowing. Donets river and its tributaries. It is established that the water management situation in the industrial cities remains unfavourable, and the level of water pollution is assessed as «dirty»

Considered original interpolation method of the working tool path using confluent two-unit manipulator. This method is based on the separation of the links on the master and slave and the use of polar coordinates to determine the incremental rotation of angle units. It is adapted for use calculating hardware with floating point.
Keywords: two-tier mechanism, circular interpolation, the kinematic model, floating point operations, the static accuracy of interpolation

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

"The concept of the nested metagraph as the model of a complex object with different levels of generalization is introduced. It is shown that the nested metagraphs reflect the general system concept for description of complex objects with synergistic effect. This approach enables moving from the set-theoretic description of complex objects to their algebraic-theoretic description, thus increasing the model adequacy to real-life objects. The application of the nested metagraphs, in particular to business-intelligence and semantic search is considered. "
