这个程序可以实现牛顿环(Newton s rings)的演示, 其中可调参数包括波长, 透镜曲率半径及最低点空气缝隙的厚度.参数的调节是通过欢快实现的,其中颜色 随波长近似的变化. 本程序可以增进读者对牛顿环的理解.(this procedure can be achieved Newton Central (Newton's rings) demonstration. with adjustable parameters including wavelength, lens curvature radius and minimum thickness of the air gap. Parameter adjustment is achieved through the jubilant, With these color changes in the wavelength approximation. The procedure can improve readers to understand the Newton ring.)

Script for computing the per symbol peak to average PAPR for an OFDM transmit waveform (loosely based on IEEE 802.11A specifications) Further, Cumulative Distribution Function (CDF) plots of the PAPR is captured

BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of Birch is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is recognized[1] as the, "first clustering algorithm proposed in the database area to handle noise (data points that are not part of the underlying pattern) effectively".
