清华大学EMC讲义，讲述了EMC现象，对EMC系统的处理方法，初学者可以下载了解一下(EMC)

求解第一类贝塞尔函数的解，主要根据初始精度设置，来调整找根的效率，仅供参考。(Solving the first kind of Bessel function of solution, mainly based on the initial accuracy Settings, to adjust to find a efficiency, is only for reference.)

MATLAB 第三代多目标性能指标计算源程序，适合于较新的多目标智能算法比较(MATLAB source the third generation of multi-objective performance index calculation, suitable for a new multi-objective intelligent algorithm)

代码是matlab编写，有例图，可直接运行（注意修改路径）。主要用来检测桥面、路面裂纹，有详细函数功能说明和算法思想，实现了路面规则条纹背景的频率估计，采用频域滤波可有效去除路面图像接近估计频率的噪声，保留目标裂纹，实现了初步的检测功能，但是功能还不完善，可作Demo供大家参考。有兴趣的朋友可以逐步完善、移植，有兴趣的朋友请与我联系。(Matlab code is written, there is case diagram, can be run directly (Note to modify the path). Mainly used to detect bridge, road cracks, a detailed description and algorithms Function thinking to achieve a frequency of road rules striped background estimation, using frequency domain filtering can effectively remove the image close to estimate the frequency of road noise, keep cracking goal to achieve a preliminary detection function, but the function is not perfect, can be used for Demo for your reference. Interested friends can gradually improve, transplant, friends who are interested, please contact me.)
