根据Zeller公式计算任意日期是星期几。说明一下，压缩包中有两个是复件，是用来压仓的，以确保满足上传条件（上传文件大于1K）。(weekday for any day)

In this project, Brain tumor in MRI is detected using image segmentation techniques. There are number of image segmentation techniques available but watershed segmentation is considered to be best among all. First of all prep-processing is to be done on MRI image followed by Segmentation. During pre-processing, MRI is first converted into gray scale image then salt and pepper noise is removed using median filter. Image is then enhanced using Histogram Equalization then Image segmentation is performed on image. In image segmentation, image is segmented into its constituent parts. In this way, brain tumor is detected.

基于simulink的逆变器交流侧下垂控制，有功功率和频率成正比，无功功率和电压成正比(Inverter AC droop control based on simulink which active power is proportional to frequency and reactive power is proportional to voltage)

说明：  对图像的傅里叶变换图像进行径向和角向频谱统计(Statistics of radial and angular spectrum of Fourier transform image)

对传统LMS算法的改进，它的步长是变化的，这样更能自适应地调整权值，因而性能比一般的LMS算法更优！(It is the improving Traditional LMS algorithm and its step size is changing every time, so it can better adapt to adjust the weights, thus the performance of this algorithm is better than the previous LMS algorithm !)
