K均值实验报告，里面有代码程序和实验结果，提供给大家参考(K mean experimental report, there are code procedures and experimental results, for your reference)

利用matlab实现COOFDM信号的调制和解调(the modulation and demodulation of COOFDM signal using matlab)

说明：  仿真算法 1）PV光伏电池模型采用工程实用C1C2数学模型； 2）采用基于占空比扰动的PO扰动观察法实现MPPT最大功率跟踪； 3）采用信号发生器和开关自由组合，实现4种工作模式：模式1，温度固定，光照固定；模式2，温度固定，光照突变；模式3，温度突变，光照固定；模式4，温度突变，光照突变； 4）跟踪效果良好，能够适应环境变化； 5）各个模块功能明确，方便学习和理解。(Simulation algorithm 1) The practical engineering C1C2 mathematical model is adopted in the PV photovoltaic cell model. 2) The maximum power tracking of MPPT is realized by using the PO perturbation observation method based on duty cycle perturbation. 3) The signal generator and switch are combined freely to realize four working modes: mode 1, temperature fixing and light fixing; mode 2, temperature fixing and light mutation; mode 3, temperature mutation and light fixing; mode 4, temperature mutation and light mutation; 4) The tracking effect is good and can adapt to environmental changes. 5) The functions of each module are clear and easy to learn and understand.)

说明：  A very concise CSS3 multi-color vertical stretch drop-down menu effect, each sub-menu item can define different colors

蓝色的星空背景，透明的旋转立方体，科幻的音效；用来做片头动画也不错-starry blue background, transparent rotating cube, the science of sound; Used in film animation is not bad

9820CAN的PCI开发板光盘内的开发例子，已经调试过，可以直接调用，花钱才可以看到的东西，免费得到了(9820CAN CD-ROM of the PCI development board with the development of examples have been debug, and can direct calls to spend money before we can see things that have been free)

说明：  JQuery image rotation plug-in is very suitable for mobile touch devices. It is highly customizable

说明：  微分进化算法的其中两个子程序，第二部分内容(Differential evolution algorithm)

管道流体中受约束力，六自由度运动，可以用于管道的涡激震动以及管道冲刷耦合模拟等(The six degree of freedom movement can be used to simulate the vortex shock of the pipeline and the simulation of pipeline scour coupling.)

This is answer for the SSD1 certification exam.
