There was a time when only the richest ham radio operators could have a radio with a panadapter. Back in the day, this was ...

Abstract: To reduce copper loss and noise caused by high-frequency pulse injection (HFPI), this article proposes a random pulse injection method based on a proportional-integral control duty cycle (PI ...

Abstract: Interior control signals derived from motor controllers have gained increasing attention in closed-loop motor drive systems for interturn short-circuit fault diagnosis. Mainstream diagnosis ...

Motion at small scales is getting harder to engineer just as medicine, electronics, and robotics demand devices that can bend without breaking. Researchers have now shown that rotation can come from a ...
