一次计算加权加速度程序

自己修改的基于closed-form的程序，对外国程序在时间上有两倍的改善，能对在复杂背景下的图片，通过画一些简单的前景线，背景线，抠图出前景(it is about matting foreground when the interested ared is located under complixed background,and then choosing some other beautiful background,you can create new image,which brings you some special feelings.thanks.)

观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图。 (Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw the spectrum map and voice waveform.)

contains MATLAB scripts and data that were used in the webinar "Using MATLAB to Develop Asset-Pricing Models." The slides from the webinar are also included. The scripts examine the Fama & French model for a number of companies with recent IPOs to examine short-term pricing anomalies in the presence of missing data. A readme.txt file in the .zip folder contains instructions

PEGASIS （电源-高效收集传感器信息系统） 是近最优基于链协议，浸出是一种进步。在节点，每个节点只与近邻通信并轮流传输到基站，从而减少了能量的数量每一轮花了。仿真结果表明 PEGASIS 优于传统 LEACH 执行约 100 到 300%，1%、 20%、 50%和 100%的节点为不同大小的网络和拓扑而死。

模糊PID用以控制电机的转速，实践证明控制效果比一般的pid效果要好(fuzzy pid is to control the morto ,the result of fuzzy pid is good)

计算机网络数据链路选择性重传实验。 　　设计一个滑动窗口协议，在仿真环境下编程实现有噪音信道环境下两站点之间无差错双工通信。信道模型为8000bps 全双工卫星信道，信道传播时延270毫秒，信道误码率为，信道提供字节流传输服务，网络层分组长度固定为256字节。(Computer network data link selective retransmission experiment. Design of a sliding window protocol in simulation programming environment there is no error duplex communication channel between the noisy environment the two sites. Channel model is 8000bps full-duplex satellite channel, the channel propagation delay 270 ms, channel bit error rate, channel provides a byte stream transmission services, network layer packet length is fixed at 256 bytes.)
