dms数据采集系统
好你 好
1、将用户的登录信息保存到系统日志文件中
2、读取系统备份文件,得到用户登陆信息,并匹配成对的记录
3、使用Socket发起TCP链接请求分配其客户线程,接收匹配好的日志文件,并将其压入到日志队列中
4、通过分配的存储线程,建立数据访问对象,将队列里弹出的匹配记录,放到oracle中,根据需求可以整合成日表、月表、年表以便计费

用于实现单片机16F648A和微控制器的通信。通过回车来确定通信是否成功,成功了可以从对应的LED开关看出,同时电脑终端会出现正确或错误的回复(This program is designed to convert 16F648A into a working micro-controller system which waits for one of a number of Carriage Return terminated messages and turn on or turn off one of four LEDs corresponding to the message. If the message is decoded successfully, an OK will be sent to the PC, otherwise an Error message will be returned )

visualmatlabImageryprocessing
调试所用Matlab版本是6.5,gatbx-toolbox是调试过程中使用的工具箱,有些热心的研友已经提供了该工具箱,之所以再贴一遍,是因为6.5版本下调试该工具箱会出现一些错误提示,在该版本中已经进行了改正,使用该工具箱只需要将压缩包下的gatbx和gatbxTest_fns加入到Matlab搜索路径即可,另外gatbx-origin是Sheffield大学提供的原始版本的工具箱,未做任何改动,两者可做比较之用
3.gatbx-example是算例调试源码和各算例的调试说明,大家可以对照原书进行比较
4.窃以为gatbx工具箱较之Matlab7新版下的gads工具箱更能让人熟悉和了解遗传算法的原理和计算过程,虽然在可视化方面不及gads
5.学习遗传算法如果首先用熟相关工具箱的话,能够先培养信心,然后更有兴趣去专研和了解具体的算法,如果就用现有的工具箱就能解决问题的话,不了解其详细的算法也未尝不可,毕竟不是每个研友都能向see_moonlight那样开发自己的工具箱吧, ( The debugging uses the Matlab edition is 6.5, gatbx-toolbox debugs the toolbox which in the process uses, somewhat warm-hearted ground the friend already to provide this toolbox, the reason that pasted again, was because under 6.5 editions debugged this toolbox to be able to present some wrong prompts, had already carried on the correction in this edition, will use this toolbox only to need to compress package of under gatbx and gatbx Test_fns joins to the Matlab search path then, moreover gatbx-origin was the primitive edition toolbox which the Sheffield university provided, has not made any modification, both might make the comparison are the example debugging sound code and various examples debugging explained with
3.gatbx-example, everybody might compare the original bookCarries on comparison
4. in my opinion under the gatbx toolbox s to be able to let the human compared with Matlab7 update gads toolbox be familiar with the understanding genetic algorithm principle and)
