A new theoretical study led by University of Delaware engineers reveals that magnons, a type of magnetic spin wave, can ...
It is not only moving objects that have varying speed. The speed of the wind and the speed of sound also vary. A typical value for the wind is about 12 m/s and the speed of sound in air is about 330 m ...
Abstract: This paper proposes a motion-reproduction method based on an iterative learning control (ILC) for variable reproduction speed. The motion-copying system consists of a motion-saving phase and ...
