Control theory: Mother nature is an engineer

In the last 150 years, engineers have developed and mastered ways to stabilize dynamic systems, without lag or overshoot, using what's known as control theory. Now, a team of University of Arizona researchers has shown that ...

Unmanned aerial vehicles

Unmanned aerial vehicles, or UAVs, are increasingly used for tasks that are too difficult or dangerous for people to complete. But better control and communication among groups of similarly tasked UAVs is still needed, experts ...

Making systems robust

The human body keeps the calcium concentration in the blood constant, similarly to an aircraft's autopilot keeping the plane at a constant altitude. What they have in common is that both the body and the autopilot employ ...

Army project develops agile scouting robots

In a research project for the U.S. Army, researchers at the University of California, Berkeley developed an agile robot, called Salto that looks like a Star Wars Imperial walker in miniature and may be able to aid in scouting ...

New discovery about terahertz radiation benefits biomedicine

Scientists from ITMO University for the first time in the world managed to directly measure the nonlinear refractive index of matter in the terahertz range. The results of the experiments were compared with previous theoretical ...
