wireless sensor networks are required to share one wireless channel among several sensor nodes. An efficient media access control (MAC) protocol must be developed and implemented on hardware. This MAC must be easily used by future users on the ta

用lingo求解飞行管理问题：在约10000m高空的某边长160km的正方形区域内，经常有若干架飞机作水平飞行。区域内每架飞机的位置和速度向量均由计算机记录其数据，以便进行飞行管理。 当一架欲进入该区域的飞机到达区域边缘时，记录其数据后，要立即计算并判断是否会与区域内的飞机发生碰撞。如果会碰撞，则应计算如何调整各架（包括新进入的）飞机飞行的方向角，以避免碰撞。-Solving problems with the flight management lingo: in the area of a

实现小球碰撞，许多个小球能够自动检测碰撞并避开，通过检测小球碰撞实代码实现(A small ball collision, many balls can automatically detect collision and avoid, by detecting the ball collision real code implementation)
