New Robobee Flies Dives Swims Explodes Out Water
2017/11/23
We’ve seen RoboBees that can fly, stick to walls, and dive into water. Now, get ready for a hybrid RoboBee that can fly, dive into water, swim, propel itself back out of water, and safely land.New flo...
Mechanical engineer Junhong Chen and a team at the University of Wisconsin, Milwaukee (UWM), have developed what you might think of as a "canary in the coal mine" for lead in water.With support from t...
Traveling wave solutions of WBK shallow water equations by differential transform method
Differential transform method (DTM) Whitham–Broer–Kaup equations Approximate long wave equation
2010/11/25
By using differential transform method (DTM) to coupled Whitham–Broer–Kaup (WBK), we find the explicit traveling wave solutions of WBK equations in the form of a convergent polynomial series. In addit...
