Chapter 13. THE LAPLACE TRANSFORM
THE LEARNING GOALS FOR THIS CHAPTER ARE:
Be able to determine the Laplace transform of signals common to electric circuits
Know how to perform an inverse Laplace transform using partial fraction expansion
Be introduced to the concept of convolution
Be able to apply the initial-value and final-value theorems
Know how to use the Laplace transform to analyze transient circuits
Micro-Aerial Robots or Tiny UAVs The size of a toy but far more than a toy, the tiny, powerful UAV—unmanned aerial vehicle or micro-aerial robot—finds its niche in such roles as advancing military missions, fighting wildfires in our national forests, or averting terrorist attacks. The UAV comes in many forms: it may be a miniature helicopter, a robo-hummingbird, or a Wasp Micro Air Vehicle. Some carry a GPS for location, a microprocessor to keep flight stable, and a color video camera. With over 5000 in operation today, Raven drones are the most popular small UAVs in the US military fleet. While they once required heavy, briefcase-sized control units, today's drones can be controlled with an iPhone.
Identified at times as a bird, a bee, or a giant mosquito, the Micro Flying Robot developed in Japan and weighing only 8 grams is driven by four micro-actuators that control two rotors and stabilizing units. Swarms of tiny UAVs can link up to form an airborne network for monitoring work too ...
