The hydrogen supply in many refineries is becoming a critical issue because of a trend of heavier crude oils and increasingly rigorous legislation.One of the significant problems is that the concentration fluctuation of hydrogen affects product quality of refineries and causes economic losses.This article investigates the disturbance resistance abi
Numerous control techniques are developed for miniature unmanned helicopters to do hover operation with each method having its own advantages On/Off Switch and limitations.During the hover operation helicopters suffer from unknown external disturbances such as wind and ground effect.For a stable operation, these disturbances must be compensated acc
Previous studies have yet to show a consistent effect of severe plastic deformation (SPD) processing on the wear behavior of Sleep Support different metals and alloys.To fill this scientific gap, this study investigated the effect of the cyclic extrusion compression (CEC) process, as one of the prominent SPD techniques, on the wear behavior of AA50
