The principle of creating a "smart" electricity meter in electric traction networks with stochastic electromagnetic processes

Voltage and current are sharply variable random (stochastic) processes in traction networks of DC electric transport systems. As a result, electronic and hybrid electricity meters used in electric systems measure electric power with a large relative error that significantly exceeds that of their accuracy class. In this paper the principle of developing smart meters for accounting the electricity transmitted from traction substations to electric rolling stock through a traction network is proposed.

Residual stresses from gravitational stress: fpreliminary estimations of their rates based on geological data

The method of the research relates to the field tectonophysics. The study of tectonic stress has always been the most important task of tectonic research. You can say that Tectonophysics began to flourish after the mass measurement of stress in-situ methods in mining and creation of stress reconstruction algorithm in natural geological data sets of slip faults. Data Mining showed a large predominance of horizontal compression environments in the areas of uplift and shields, and the prevalence of certain environments the horizontal extension in the crust basins and plates.
