    Abstract: This article describes a method for predicting the values of track’s geometric characteristics during the period between two consecutive measurements. As is known, track condition analysis is based on periodic measurements of geometric parameters. Changes in track condition manifest as an increase in the size of “large” defects and a decrease in “s... Show More

    Abstract: This article is dedicated to the detection and calculation of unavoidable gas losses due to the measuring devices and technological processes of auto-gasification pressure stations (CNGs), which are conditioned by the productivity of CNGs. The productivity of CNG stations operating in the territory of RA differs according to their daily charging ca... Show More
