无控制ASV

PSO算法就是模拟一群鸟寻找食物的过程，每个鸟就是PSO中的粒子，也就是我们需要求解问题的可能解(The PSO algorithm is a process of simulating a group of birds looking for food. Each bird is a particle in the PSO, that is, we need to solve the problem.)

说明：  这里有很详细的元器件封装，可以方便大家绘制自己的PCB,简单快捷，而且十分的好用。(Here is a very detailed package of components, you can easily draw your own PCB, simple and fast, and very useful.)

此代码是本人一年前所编写 对JAVA初学者可能会又帮助 在数据库连接上 效率较高-year ago, I prepared for Java beginners may also help connect the database more efficient

说明：  计算自由曲面透镜的轮廓坐标点，得到坐标点后导入solidworks等建模软件可以得到透镜模型。(Calculate the outline coordinate points of free-form surface lens, get the coordinate points and import SolidWorks and other modeling software to get the lens model.)

说明：  K-means算法是基于划分的思想，因此算法易于理解且实现方法简单易行，但需要人工选择初始的聚类数目即算法是带参数的。类的数目确定往往非常复杂和具有不确定性，因此需要专业的知识和行业经验才能较好的确定。而且因为初始聚类中心的选择是随机的，因此会造成部分初始聚类中心相似或者处于数据边缘，造成算法的迭代次数明显增加，甚至会因为个别数据而造成聚类失败的现象。(K-means algorithm is based on the idea of partitioning, so the algorithm is easy to understand and the implementation method is simple and feasible, but it requires manual selection of the initial number of clusters, that is, the algorithm is with parameters. The number of classes is often very complex and uncertain, so professional knowledge and industry experience are needed to better determine. Moreover, because the selection of initial clustering centers is random, some initial clustering centers will be similar or at the edge of data, resulting in a significant increase in the number of iterations of the algorithm, and even the phenomenon of clustering failure due to individual data.)

防火墙和网络安全方面的测试规范和国家标准，主要是将硬件防火墙。-Firewall and network security test standards and national standards, primarily the hardware firewall.

opnet网络仿真 清华出的，陈敏编辑，学习opnet的必读的书。主要是opnet Modeler Tutorials 翻译，对于看英语头疼的人来说，阅读非常容易~(OPNET_network_simulation)

WLAN仿真－发送机 wlan No Comments 设置完系统参数后，开始产生发送数据。 1. 产生随机的发送bit（tx_bits），这里不考虑信道编码。 2. QAM映射 3. 将数据映射到不同载波，形成OFDM符号 4. 产生pilot，并将pilot插入OFDM符号中 5. 加入dc和guard子载波 6. 进行ifft，将频域信号变到时域，并加入循环前缀 7. 对信号进行overlap window 8. 在时域产生short preamble 9. 在时域产生long preamble 10. 将preamble和数据符号组成packet 11. 升采样 得到信道传输的数据Tx_signal_up 具体程序见附件 wlan_transmitter.m-WLAN Simulation- wlan No Comments transmitter system parameters set finished, the beginning to have to send data. 1. Have sent random bit (tx_bits), here does not consider channel coding. 2. QAM mapping 3. The data is mapped to a different carrier to form OFDM symbols 4. Have a pilot, and pilot inserted OFDM symbols 5. Adding dc and guard subcarriers 6. To carry out ifft, will change the frequency domain signal to time domain, and add cyclic prefix 7. the signals overlap window8. In the time domain have a short preamble9. In the time domain have a long preamble10. the preamble and data symbols packet11. or sampling re
