Spurred by the rapid integration of unmanned aerial vehicles (UAVs) in modern military missions, significant research has been performed in the field of autonomous aerial refueling with a focus on the detection, control, and guidance of the tanker and receiver.The concept of aerial refueling has been highly valued in the military since it was first
The maglev linear motor has three degrees of motion freedom, which are respectively realized by the thrust force in the x-axis, the levitation force in the z-axis and the torque around the y-axis.Both the thrust force and levitation force can be seen as the sum of the forces on the three windings.The resultant thrust force and resultant levitation
Playing Cards Heat transfer analysis can be studied efficiently with the help of so-called modern dimensional analysis (MDA), which offers a uniform and easy approach, without requiring in-depth knowledge of the phenomenon by only taking into account variables that may have some influence.After a brief presentation of the advantages of this method
Liquid-assisted grinding (LAG) with dimethyl sulfoxide (DMSO) can prepare a variety 123 of palladium-bipyridine complexes much more rapidly than by ball milling the neat powders.The added liquid is non-innocent, and reacts to form Pd-DMSO species prior to formation of the final complex.Formation of a metal-DMSO intermediate leads this process to be
