卫星拒止环境下无人机安全问题是众多学者研究的热点.增加传感器数量虽然可以获得更多的信息,但是给无人机平台带来了更多的负担和干扰.因此,利用尽可能少的传感信息实现无人机群安全飞行值得研究.鉴于此,研究仅利用距离信息实现多个体之间的碰撞预测.预测方案中提出利用矩阵填充的方法弥补通信测距丢包的难题,使用均值检验进...
German-American architect, futurist and inventor Wolf Hilbertz pioneered BioRock in the 1970s as a means of growing artificial reefs to benefit coral and other forms of marine life. When a small electric current is passed between underwater metal electrodes in seawater, dissolved minerals accrete ...
