Abstract: Achieving array performance comparable to a uniform array with a reduced number of array elements has the potential to greatly decrease costs and simplify array design. The enhanced matrix ...

Abstract: In global navigation satellite system (GNSS)-denied scenarios, odometer/inertial navigation system (INS) integration for train positioning tends to diverge due to accumulated attitude errors ...

For decades, scientists have tried to better understand this underground system. Until recently, they were unaware what the subsurface actually looked like. In the past, geoscientists relied on ...

Underneath Yellowstone National Park in Wyoming lies a complex plumbing system of hot water, steam and rock that fuels the park’s magnificent geysers and hot springs. For decades, scientists have ...
