中国有句老话，“三天打鱼两天晒网”。假设渔民老张从1990年1月1日开始“三天打鱼两天晒网”，那么请你帮助推算出在以后某一天中，老张是在“打鱼”，还是在“晒网”。(Chinese saying goes, " in fits and starts network." The assumption that the fishermen Zhang from January 1, 1990 " in fits and starts network, then you figure out at a later day, Zhang is in the" fishing " , or" drying nets " .)

ghost之后自动修改计算机名和工作组，并且可以根据mac地址来制定计算机名(ghost after automatic modification of computer and the work group, and under the mac address to develop computer name)

XueTr算是目前最强的反rootkit工具了，本程序完成了对Xuetr的注册表项的隐藏，采取的方式是驱动绕过，而不是简单的GUI HACKER。(XueTr considered to be the most powerful anti-rootkit tool, the program completed Xuetr hidden registry keys, takes the form of driving around, rather than a simple GUI HACKER.)

说明：  北京大学ACM竞赛试题集锦，希望对你的编程能力因为它而更上一层楼，它的算法设计方面很有帮助对你(Beijing University ACM Collection questions, and I hope to your programming capability because it is being, it's helpful in the design of algorithms to you)

使用VC生成COM组件的方法，里面对VC生成不同形式的COM接口参数的方法，对COM组件不熟悉的朋友会是一个很好的学习资料！(COM components using VC generation method which generates on the VC parameters of different types of COM interfaces methods, and COM components are not familiar with the friend would be a good learning materials!)

说明：  一个排队叫号器支持多功能....有源代码,资料齐全(call and queue)

在菜单中加入图标 Add an icon to the menu(Add icon to Add an icon in the menu to the menu)

PLC动态库 vb编程 支持s7-1200(PLC Dynamic Library Support s7-1200)

应老师要求做的VB课后练习内容，这是第二个实验内容。(This is the second test.)

在实际应用中，原始的BP算法很难胜任，因此出现了很多的改进算法。BP算法的改进主要有两种途径，一种是采用启发式学习方法，另一种则是采用更有效的优化算法。本例采用动量BP算法，来实现对网络的训练过程，动量法降低了网络对于误差曲面局部细节的敏感性，有效地抑制网络陷于局部极小。 (In practical applications, the original BP algorithm very difficult to do, so there were a lot of the improved algorithm. BP Algorithm There are two main channels, a heuristic learning method is adopted, another is the introduction of more efficient optimization algorithm. In this case the use of momentum BP algorithm to realize the network training process, momentum method to reduce the network error surface for the local details of the sensitivity of the network effectively inhibited in a local minimum.)
