电力系统静态稳定计算一般采用小干扰法,即首先计算近似的线性微分方程组系数矩阵的特征根。然后根据特征根在复平面上的特性,判别电力系统运行的稳定性 操作说明: 请输入初始功率S0,形如a+bi 请输入无限大系统母线电压V0 请输入系统直轴等值电抗的大小Xd 请输入同步电角速度 请输入惯性时间常数Tj 请输入综合阻尼系数D

Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution % % compute the forward/backward Campbell/specgtrogram % % INPUT: % y (n x 2) each column is measured from a different sensor % /////// % __ % |s1| y(:,1) % |__| % __ % / \ ________|/ % | | | s2 |/ y(:,2) % \____/ --------|/ % % Fs Sampling frequnecy % % OUTPUT: % B spectrogram/Campbel diagram % x x-axis coordinate vector (time or Speed) % y y-axis coordinate vector (frequency [Hz])

分享好书(good):台湾人的著作《Spring 技术手册》等 在网上找到了台湾java专家林信良的著作 《Spring 技术手册》的电子书和大家分享下~~~只是缺了AOP的介绍,不过已经很全面了,台湾技术书籍的特点:通俗易懂,深入浅出,结合实例~~~顺便也带上其它的几本Struts,Hibernate~~ 不过,全是繁体字的哦。。。。 另外,《Spring 技术手册》左边的index tree 是乱码!

Wavelets have widely been used in many signal and image processing applications. In this paper, a new serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is done using a tree of carry save adders to ensure the high speed processing required for many applications. The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis reveals that the proposed architecture, implemented using current VLSI technologies, can process a video stream in real time.
