Thin AZ31 magnesium alloy sheets, i.e., 2 mm thick, are welded by Friction Stir Welding (FSW) in butt joint configuration using gap width up to 1.15 mm.All welds present good surface finishing and no internal defects, except for the weld produced using the maximum gap Body Lotions width.A reduction of the weld thickness within the Stir Zone is seen
The Leadership the World Needs
As Dispenser To Pump Hose society evolves in consciousness, the character of its leadership evolves as well.The physical stage of human development is characterized by the rule of physical strength and directed by military leaders with the capacity to mobilize and exercise physical force through violence.In the vital-social stage, leadership shifts
Unidirectional transport of both wettable and nonwettable liquids on an asymmetrically concave structured surface
Unidirectional liquid transport (UDLT) has been widely used in various fields as an important process for transferring both mass and energy.However, UDLT Ginger driven by a structural gradient has been witnessed for a long time only in wettable liquids.For nonwettable liquids, UDLT can hardly proceed merely by a structural gradient.Herein, we propo
Multiscale Maize Tassel Identification Based on Improved RetinaNet Model and UAV Images
The acquisition of maize tassel phenotype information plays a vital role in studying maize growth and improving yield.Unfortunately, detecting maize tassels has proven challenging because of the complex field environment, including image resolution, varying sunlight conditions, plant varieties, and planting density.To address this situation, the pr
Direct Current Deadbeat Predictive Controller for BLDC Motor Using Single DC-Link Current Sensor
BLDC motors are characterized by electronic commutation, which is performed by using an electric three-phase inverter.The direct control system of the BLDC motor consists of double loops; including the inner-loop for current regulating and outer-loop for speed control.The operation of the current controller requires feedback of motor currents; the
