    这是一个关于商人visit许多城市,怎样走法才能使距离最短的例子,采样的了退火算法的经典案例(Traveling Salesman Problem (TSP) has been an interesting problem for a l me in classical optimization techniques which are based on linear and nonlin ogramming. TSP can be described as follows: Given a numberof cities to v d their distances from all other cities know, an optimal travel route has to und so that each city is visited one and only once with the least possible dista aveled. This is a simple problem with handful of cities but becomes complica the number increases.)

    in this work we have tried to control a tanker ship using fuzzy logic and fuzzy controllers. it s well known that we can use fuzzy logic for control purposes in two ways,first we can use fuzzy logic to make a model of the plant and use conventional controllers to control the whole system controllers like PID,or nonlinear methods like Sliding mode control or ... on the other hand we can use fuzzy logic algorithms and methods for direct control of the plants. in this work we have used the second one and have propsed a fuzzy algorithm to control the tanker vehicle directly.

  • Rapid-Acquisition-of-Doppler-Shift-
    本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性,缩短多普勒频移的 捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式,然后根据数值分析结果得到了准最佳捕获判决策略,最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高. (This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)
