    • System of Laser Monitoring of Water Pollution with Application of Relative Description of Signal Shape 

      Alekseev, V. A.; Yuran, S. I.; Usoltsev, V. P.; Shulmin, D. N. (БНТУ, 2020)
      As a rule, the wastewater treatment system is not designed to filter substances formed, as a result of beyond design basis accident. The nature of the beyond design basis accident is associated with the shortterm appearance of a clot of these substances in wastewater, determined by the volume of the substance storage tank. Therefore, a rational approach is to divert this portion ...
