- 某城区有 36 个垃圾集中点，每天都要从垃圾处理厂（第 37 号节点）出发将垃圾运回。现有一种载重 6 吨的运输车。每个垃圾点需要用 10 分钟的时间装车，运输车平均速度为 40 公里／小时（夜里运输，不考虑塞车现象）；每台车每日平均工作 4 小时。运输车重载运费 1.8 元 / 吨公里；运输车和装垃圾用的铲车空载费用 0.4 元 / 公里；并且假定街道方向均平行于坐标轴。请你给出满意的运输调度方案以及计算程序。,City have a focal point 36 of refuse ever

- 争对移动声源采用波束形成进行语音增强，提出一种约束子带波束形成算法。其波束形成器基于一个软约束，其目的是要使波束指向特定的区域即声源方向。而其核心在于首先要进行声源定位，获得尽量准确的方位信息，然后构造软约束条件，用于波束形成。且在此过程中不断跟踪声源的移动情况。在构造的约束条件中，需要知道声源的二维信息，即与麦克风阵列的距离和方向角，“软”体现在对距离和方向角的确定都是在一定范围内的，有待进一步更正。-Between the mobile sound source using beamform

- 采用滤波器组，将盲分离与声源定位结合在一起。滤波器组中分别进行子带处理，并且在每个子带中进行声源定位，最后综合所有子带估计的方向得到多个声源的方位信息，同时将声源信息作为ICA分析的约束条件，可以在色噪声及多得到更好的盲分离效果。其优势在于用滤波器组进行多次的估计声源方向，再加以合适的权值均衡后即可得到更优的估计。-The use of filters will be blind source separation and sound localization together. Filter

- 为虚拟管家系统设计一个麦克风阵列接口，该接口用于接收语音信号作为命令，由麦克风接收识别后用来控制虚拟管家，进而控制各种家用电器工作。当用户移动时，该接口可以跟踪定位用户（此应用中只需知道用户方向角，也是一维定位），即可随时响应用户的控制命令-Housekeeper system for the design of a virtual microphone array interface, the interface for receiving voice signal as a command,

- 结合马尔可夫过程，提出一种概率论的声源定位算法，并给出了基于DSP的机器人实现。其中声源定位部分采用三个麦克风呈三角形放置，为减小由于噪声等引起的TDOA估计误差，采用马尔可夫过程计算时延，这样计算的时延会更可靠。该方案中的声源定位也属于一维定位，即只需知道声源的方向角-Combination of Markov process, a probability theory of sound source location algorithm, and give the robot based o
