DC Micro Grid Simulation

《PB实用技巧集锦》适合新手,看了此书，pb成长应该会很块(" PB practical skills Collection" for novice, read the book, pb growth should be very block)

说明：  sql学习必备材料，讲解通俗易懂，很有层次，内容丰富(This book is SQL learning materials and understanding very easy and very hierarchical and riching in content)

在MATLAB中求图像纹理特征，多机电力系统仿真及其潮流计算，matlab开发工具箱中的支持向量机。( In the MATLAB image texture feature, Multi-machine power system simulation and flow calculation, matlab development toolbox support vector machine.)

说明：  贝塞尔离散点拟合，最高拟合21阶，阶数太高计算会溢出(Bessel discrete point fitting, the highest fitting order is 21. If the order is too high, the calculation will overflow)

ARRAYS的数十种代码(ARRAYS dozens of kind of codes )

说明：  These exercises and projects were originally the even-numbered exercises in the first edition. (The first edition did not distinguish between exercises and programming projects.) For the benefit of readers who have the first edition, the original exercise number is given in square brackets. For example, the notation [was #4] indicates that the number of the exercise (or programming project) was 4 in the first edition. If an answer is different because of second-edition changes, the word "modified" will appear inside the brackets: [was #4; modified].These exercises and projects were originally the even-numbered exercises in the first edition.

说明：  《信号与系统》课本，郑君里，应启珩，杨为理。 第三版清晰版本, 第二版较清晰版本("Signal and system" textbook, Zheng Junli, should be Qi Heng, Yang Weili Clear version of the third edition, clear version of the second edition)

有了合适的处理对象，剩下的就是技术问题了。在数字运动检测中运用的关键技术有图像数据读取、图像的中值滤波、图像灰度化、图像梯度的获取、图像特征区域的确定、两幅图像的匹配、图像二值化、图像细化、图像去离散点的操作、物体的区域定位、物体中心点的取得，最后再从图片中得到物体运动轨迹。本运动检测系统是为了实现对一系列图片中运动物体的跟踪而设计的，它通过对一系列图片的处理，提取出图片背景，识别出运动物体，进而对运动物体进行跟踪，得到物体运动的轨迹。本文主要阐述了什么是数字图像处理、数字图像处理的基本要求、数字图像处理的实践及开发工具的特点、功能、()

基于互功率谱的时延估计，计算互信息非常有用的一组程序,music高阶谱分析算法。( Based on the time delay estimation of power spectrum, Mutual information is useful to calculate a set of procedures, music higher order spectral analysis algorithm.)

主要是基于mtlab的程序，包含特征值与特征向量的提取、训练样本以及最后的识别，小波包分析提取振动信号中的特征频率。( Mainly based on the mtlab procedures, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Wavelet packet analysis to extract vibration signal characteristic frequency.)
