  • 简介:在在武汉区域的GPS气象学网络的学习有三个方面。第一是在相对系数为是99.97的最后的位置推算历和超速的位置推算历之间的GPS可降水蒸汽的比较,根平均数摆平是0.048公里。超速的位置推算历能被用来为即时预言得到GPS可降水蒸汽,这能被结束。第二是GPS车站的可降水蒸汽的比较,在武汉区域的水汽的分发被获得。在一个降雨过程的GPS可降水蒸汽和降雨的变化被比较并且分析。GPS可降水蒸汽的变化能反映并且预言降雨的过程。

  • 简介:这篇论文在指导网络调查控制动态代理人的全球行为。代理人是Lyapunov马厩,在一根线被散布,并且通过一个指导网络交流。网络的通讯拓扑学被一张指导的图描绘,控制协议在简单线性分散的反馈法律被设计。我们学习代理人将分别地在下面完成聚集,和批评、分叉的轨道的不同条件。我们在网络下面的动态代理人系统上的调查被扩大到时间延期网络案例。而且,我们与二学习案例在系统的预先指定的虚拟领导人。数字模拟被给并且证明我们的理论结果是有效的。
