MATPOWER is designed to give the best performance possible while keeping the code simple to understand and modify.)

AWGN信道的设计与仿真加性高斯白噪声在通信领域中指的是一种各频谱分量服从均匀分布（即白噪声），且幅度服从高斯分布的噪声信号。因其可加性、幅度服从高斯分布且为白噪声的一种而得名。(Design and Simulation of additive white Gaussian noise AWGN channel in the middle of the field of communication is a uniform distribution of each spectral component (ie, white noise), and the amplitude of the noise signal to obey a Gaussian distribution. Because it can increase resistance, the magnitude of Gaussian distribution and is named after a white noise.)

利用多尺度小波分解函数dwt2对图像进行二尺度小波分解（仍然采用db1小波）((Still using db1 wavelet multi-scale wavelet decomposition of the two-scale wavelet decomposition function dwt2 image))

网络服务正在更新换代并且可扩展设备被设计成可提供在元计算环境中动态资源行为预测。这篇文章里，我们描述了预测产生的的设计和预测行为的细节。当预测方式为普通方式时，我们关注与他对TCP/IP端到端吞吐量能力的预测和在不同地点使用不同系统会带来的延迟量。因为在元计算软件的基础上网络预测需要计划的支持和质量服务保证的提高。(The Network Weather Service is a generalizable and extensible facility designed to provide dynamic resource performance forecasts in metacomputing environments.In this paper,we outline its design and detail the predictive performance of the forecasts it generates. While the forecasting methods are general,we focus on their ability to predict the TCP/IP end-to-end throughput and latency that is attainable by an application using systems located at differentsites.Such network forecasts are needed both to support scheduling (Bermanetal.,1996)and,by the metacomputing software infrastructure,to develop quality-of-service guarantees(DeFantietal.,to appear Grimshawetal.,1994). )

DFP法，变尺度法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(DFP method, variable metric method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)

说明：  五点三次平滑法可用作时域和频域信号平滑处理。对时域作用是减少混入振动信号中的高频随机噪声。对频域是能使谱曲线光滑。(Three five-point smoothing method can be used as time domain and frequency domain signal smoothing. Effect on the time domain vibration signals to reduce high-frequency mixed with random noise. On the frequency domain is the spectral curve can smooth.)
