This work is aimed at crea Irkutsk ting a domestic switching IT platform that organizes commercial and technological data exchange with intelligent metering devices within the Kumir-Resource complex. To facilitate efficient control and management of the modern pipe line and electric grid infrastructure an IoT (Internet of Things) platform can be built to organize communication with a multi-million audience of end consumers using smart metering devices. Implementation of such a platform will allow centralized collection, monitoring, management, analysis and visualization of all pipeline system data.

This article is devoted to the development of a monitoring system of Lake Baikal. The developed system should provide ongoing monitoring of hydrophysical parameters of water in different areas of the lake, which will allow identifying signs of environmental pollution of Lake Baikal timely. A distinctive feature of the created system is high productivity at low economic costs per accounting point. The appropriate selection of the component base and software optimization of algorithms will allow achieving the maximum range of data transmission at a distance of up to 100 km in an open area. The interim results of the monitoring system development are presented, the tasks for the current year are defined.

The authors examine the influence of high-speed milling on the distribution of residual stresses in parts made of structural high-strength aluminum alloys Al-Cu-Mg, which are the main structural materials in the aerospace industry. Milling was carried out at high cutting speeds. Different tool settings were used to balance the instrument. Plastic deformation occurred in the part’s surface layers. Residual stresses were measured by the X-ray method. It was found that high-speed milling creates residual compressive stresses that are favorable for the operation of the part. The depth of the residual stresses depends on the cutting mode. The article shows the relationship between residual stresses and the type of metalworking tool, processing conditions in structural parts made of high-strength aluminum alloys.
