  1. Motivated by this observation, this paper studies the problem of efficiently processing k nn k - ge 1 search on r - tree - like structures storing historical information about moving object trajectories. two algorithms are developed based on best - first traversal paradigm, called bfp k nn and bft k nn, which handle the k nn retrieval with respect to the static query point and the moving query trajectory, respectively. both algorithms minimize the number of node access, that is, they perform a single access only to those qualifying nodes that may contain the final result

    例如,若已知動物的軌跡,則動物學家可能提出如下兩種查詢: i在時間區間ti , tj內找到離一個給定的靜態點譬如食物源實驗室等最近的k條動物軌跡ii在時間區間ti , tj內找到離一條預先指定的動物軌跡最近的k條動物軌跡。
  2. Design the optimal climb trajectory of the attack uav in the vertical plane using nonlinear programming. the calculation result states that the final altitude predetermined can be climbed fast and there are beter the profit in performance according to the climbing trajectory optimized

    應用非線性規劃方法對無人機在垂直平面內的最優上升軌跡進行優化設計,經優化后的爬升軌跡可以快速爬升到預定的終點高度,具有較好的性能效益。
  3. Then, we use a simulation method to create a large number of radar measurement values, produce a quantity of random numbers using computer software and add them to the radar measurement values, we use kallman filtering method to calculate the location, velocity and trajectory coefficient of the target at the moment of the final tracking point, and use the numerical solving method of differential equation to calculate the trajectory, the location of the hostile artillery or the impact point of its own projectiles, finally, we calculate statistically the random error of the tracking system and analyze the location accuracy

    然後採用模擬模擬方法獲得大量的雷達測量值,由計算機軟體產生大量的隨機數,加入雷達測量值中,用卡爾曼濾波法計算出最後跟蹤點時刻的目標位置、速度和彈道系數,再用微分方程數值解法計算出整個彈道軌跡、計算出敵方炮位的位置或己方炮彈的落點,最後統計出跟蹤系統的隨機誤差,分析定位精度。
