That's a lot of zeros and red ink to worry about. The gross federal debt of the United States has just topped the $38T level, only two months after surpassing $37T. For those keeping tabs, that's the ...

Long before modern navigation, sailors looked to the stars and followed constellations to cross open seas. Centuries later, diesel engines, radar, and GPS reshaped that journey—turning intuition into ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

Vancouver has the World's Longest Uninterrupted Waterfront Path, also known as the Vancouver Seawall. The Seawall starts at Canada Place, walks around Stanley Park, past English Bay, into False Creek ...

Traditional path planning algorithms often face problems such as local optimum traps and low monitoring efficiency in agricultural UAV operations, making it difficult to meet the operational ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

Unmanned surface vehicles (USVs) nowadays have been widely used in ocean observation missions, helping researchers to monitor climate change, collect environmental data, and observe marine ecosystem ...

Abstract: This paper investigates the shortest path planning of unmanned surface vehicles (USV) in complicated marine environments. A novel path planning method called “sunlight algorithm” is first ...
