measurement automation

The paper presents a comprehensive analysis of the application of trapezoidal weirs coupled with automated measurement systems for the precise determination of seepage flow rates through earth dams at hydroelectric power plants. A key focus is placed on the hydraulic operating modes of these weirs, particularly the distinction between non-submerged and submerged conditions. The paper details the results of extensive laboratory studies conducted to quantify the impact of submergence on the discharge capacity of trapezoidal weirs.

Purpose. Solids microsurface digital images obtained with scanning electron microscopes (SEM) are characterized by significant geometric distortions, which must be defined and taken into account when determining the quantitative parameters of microsurface solids with high accuracy. Therefore, this problem is so important and urgent, especially during the high-tech quality control of production processes using nanotechnology, particularly in mechanical engineering, aircraft construction, and for creating space and military equipment.
