Purpose.The solution of actual problem of active suppression of resilient electromechanical vibrations in an electric drive with the astatic system of automatic control is presented.Methodology.For research of damping properties of electrical drive according to a flow diagram from transmission functions on regulation and indignation a characteristi
Flexible pipelines connect offshore platforms to subsea production systems due to their high flexibility, applicability, and recycling.Flexible armor layers in flexible pipelines are constructed using the parallel helical wrapping of several rectangular wires.The complex stress Ottoman modes to which pipelines are subjected provide complex failure
For monitoring Shenhua locomotive status in real time, such as location, speed, etc., to dispose on-board failure Body Parts of locomotive, and improving operation efficiency and safety, remote real-time status monitoring system for Shenhua locomotive based on WebGIS was designed with functions such as locomotive location, track trailing, status mo
The water cooling system plays an important role in the high-voltage direct current (HVDC) converter station.To reduce the leakage current among metal components, a certain number of platinum electrodes are installed at the distributary pipes.However, due to electric field distortion around the platinum electrode, over 66% faults of the cooling sys
The study was conducted in Tehulederie, Kalu, and Dessie Zuria districts of South Wollo Zone, Amhara, Ethiopia, to assess the current beekeeping production system with available opportunities and challenges facing the beekeeping subsector.The districts were purposively selected based on potential and accessibility and then stratified into lowland,
