说明：  VB人力资源管理系统（Access版源码）,有需要的下吧。(VB (Access version of the source), human resource management system in need of it.)

真实的世界建模，基于ejb实现的一个建模实例(real world modeling, based on the achievement of a ejb Modeling)

说明：  是3GPP中GSM最重要的标准,业内简称GSM0505 这个标准详细规定了GSM发射与接收技术,其中GMSK,8-PSK,B(GSM0505 is the most important standard of GSM in 3GPP, which specifies the GSM transmitting and receiving technology in detail, including GMSK,8-PSK,B)

VC++实现的多线程系统清理程序，可清理系统垃圾文件，使用的是多线程技术，有必要一看，内核仿360的(VC++ implementation of the multi-threaded system cleaning program can clean up the system junk files, using multi-threading technology, it is necessary to look, kernel imitation 360)

p-持续CSMA协议下，一个用户在发送之前，先侦听信道，若是空闲，就以概率p发送出去，而以q =1-p的概率推迟到下一帧时。如果下一帧时仍是空闲，便再次以概率p发送而以q推迟到再下一帧时。直到发送成功或另外一用户开始发送时为止。若一开始就侦听到信道忙，它就等到下一帧时，然后再开始上述过程。若发生冲突，这等待一随机时间后重新开始。本实验中取q值为0.5。求的是0.5-持续CSMA。 -p-persistent CSMA agreement, a user before sending the first interception channel, if idle, with probability p sent, and to q = 1-p probability postponed to the next frames. If the next frame was still idle, they again sent with probability p and q to further postponed to the next frames. Until this a success or other users at the beginning of this date. If an interception at the start of the busy channel, it will wait till the next frames, and then begin the process. If conflict breaks out, waiting for a random period of time after the re-start. The experiments take q value of 0.5. For the 0.5-sustained CSMA.

起飞文章管理系统采用一级分类，界面简洁大方，功能简单易用，可远程自动上传图片，删除文章后，文章相关图片也一并删除减少垃圾文件的存在。后台管理入口http://域名/admin 用户名和密码都是admin(Takeoff article management system using a classification, simple and elegant interface, easy to use functions, remote automatically upload pictures, delete the article, the article s picture also be deleted to reduce the presence of junk files. Manage entry http: // domain/admin user name and password are admin )
