Butterworth Filter (digital image processing)

利用大数据处理框架+实时内存计算处理海量数据,再利用协同过滤算法等实现电商系统对于用户购买及推荐类似商品的精准定位(Using large data processing framework + real-time memory computing to process massive data, and then using collaborative filtering algorithm to achieve accurate positioning of e-commerce system for users to purchase and recommend similar goods)

说明：  三相并网逆变器的simulink仿真)动力学特性的数学模型，故采用重复PI 控制的APF(Simlink simulation of three-phase grid-connected inverters)

问道PAK工具免费不限功能版，支持多级目录............(PAK tools free unlimited function version, support multi-level directory......)

说明：  simplis-ir3847 电路设计，非常好，省略了二极管(Circuit design of simplis-ir3847)

说明：  卫星气象中心发布的NOAA卫星数据格式文档。(NOAA 1B satellite data format guide by NSMC.)

数值分析分析中 用jacobi迭代求解线性方程(Analysis of numerical analysis using jacobi iteration for solving linear equations)

分析两自由度系统的动力学特性，包括频率，振型，频率响应函数等动特性计算， 自由振动和强迫振动响应计算。(The dynamic characteristics of the two degree of freedom system are analyzed, including frequency, mode, frequency response function, free vibration and forced vibration response calculation.)

使用Opencv+Zbar组合识别图片中的二维码，特别是标准的二维码，这里标准指的是二维码成像清晰，图片中二维码的空间占比在40%~100%之间，这样标准的图片，Zbar识别起来很容易，不需要Opencv额外的处理。(The Opencv+Zbar combination is used to identify two dimensional codes in the picture, especially the standard two-dimensional code. Here the standard refers to the two-dimensional code imaging clearly, and the space of the two-dimensional code in the picture is between the 40%~100%. So the standard picture, Zbar is very easy to recognize, and does not need additional processing of the Opencv.)

应用背景交通信号是一个常见的事情，我们看到在我们的日常生活但实现它是某种有点困难。此代码是正确的工作关键技术AVR Studio是用于开发代码。希望你会喜欢我的工作。
