[Nicholas Rehm] works during the day at the Applied Physics Laboratory at Johns Hopkins, Maryland, so has considerable experience with a variety of UAV applications. The question arose about how the ...

Have you ever tried to balance a broomstick or dowel on the tip of your finger? It’s not so easy. Just how fast should you move your hand to keep the stick balanced? How should you respond if somebody ...

Researchers have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation. The technique is comparable to methods used for controlling an inverted pendulum ...

This is a preview. Log in through your library . Abstract An explanation and a proof of stability of the inverted pendulum whose suspension point undergoes vertical periodic oscillations is given. The ...

It has been argued that brachiation is an energetically cheap way to move since, like a swinging pendulum, it involves an alternate storage and recovery of kinetic energy in gravitational potential ...
