学生管理系统
本系统仅仅是对在校学生进行简单管理的系统。对于用户,本系统共分为三种不同的登录用户,分别是管理员、教师和学生,三种不同用户对应不同的权限,其中管机员权限最高,其次是教师,最后是学生;针对三种不同的用户所实现的功能不同,并且在系统中接触到的信息也不同。对于功能,本系统共分为学生信息管理、学生成绩管理和学生课程管理三大模块,其中每个大模块中有下分了众多不同功能。总之,通过本系统可以对学生进行比较全面的、系统的管理。

在大多2440开发板BSP中的SMDK2440DRIVERSacklite目录下一般都有背光驱动。在注册表中添加如下函数的时候,开机时确实可以打印"!!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!,如果没有操作大概1分钟后也可以打印!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!。但打印("!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!后,就算有触发事件(在触摸屏上点击,或者移动鼠标)也不会打印"!!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!。
其实这个驱动大体是正确的,只是当键盘鼠标或触摸屏输入时候gwes 发送“PowerManager/ActivityTimer/UserActivity” event,而不是原驱动中的“("UserInputEvent") ”修改后的源程序如下(SMDK2440DRIVERSacklite目录下bak_hw.cpp文件)。-2440 development board in the majority of BSP in SMDK2440 DRIVERS backlite directory generally backlight driver. Add the following in the registry function, the boot print when really " !!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!, If there is no operation after about 1 minute can also print it !!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!。 Print (" !!!!!!!!!!!! BACKLIGHT OFF!! !!!!!!!!!! after, even if there are triggering events (click on the touch screen, or move the mouse) will not print " !!!!!!!!!!!!

基于随机波束形成的多
针对基于随机波束成形的多用户MIMO下行系统提出了三种调度算法:后端比例公平门限调度算法,后端最大值调度算法和后端比例公平最大值调度算法。通过仿真表明,这三种算法相比其他调度算法,在基本保持系统性能的前提下,能够降低反馈率,且有各自的特点和适用性:后端比例公平门限调度算法随着小区内用户数目的增多,反馈率越小,适合用户数较多的情况;后端最大值调度算法和后端比例公平最大值算法在用户数目较多的情况下,系统性能基本保持不变,且随着子信道数目增加,反馈率越小,适合天线数和用户数都较多的情况。-Based on random beamforming for multi-user MIMO downlink system proposed three kinds of scheduling algorithms: back-end proportional fairness scheduling algorithm threshold, the maximum back-end and back-end proportional fairness scheduling algorithm for the maximum scheduling algorithms. The simulation showed that the three kinds of algorithms compared with other scheduling algorithms, the basic premise of maintaining system performance, can reduce the feedback rate, and have their own characteristics and applicability: the back-end proportional fairness scheduling algorithm with the threshold number of users within a cell increases, the smaller the response rate for the number of users are more situation back-end and back-end ratio of the maxi

十字链表是这样构成的:用链表模拟矩阵的行(或者列,这可以根据个人喜好来定),然后,再构造代表列的链表,将每一行中的元素节点插入到对应的列中去。书中为了少存几个表头节点,将行和列的表头节点合并到了一起――实际只是省了几个指针域,如果行和列数不等,多余的数据域就把这点省出的空间又给用了。这点小动作让我着实废了半天劲,个人感觉,优点不大,缺点不少,不如老老实实写得象个十字链表,让人也好看一些,这是教科书,目的是教学。实在看得晕的人,参阅C版的这部分内容,很清晰。我也不会画图,打个比方吧:这个十字链表的逻辑结构就像是一个围棋盘(没见过,你就想一下苍蝇拍,这个总见过吧),而非零元就好像是在棋盘上放的棋子,总共占的空间就是,确定那些线的表头节点和那些棋子代表的非零元节点。最后,我们用一个指针指向这个棋盘,这个指针就代表了这个稀疏矩阵-Crusaders is the form : Chain Simulation matrix rows (or out, This can be based on individual preferences to be), and then constructed on behalf of the chain out, Each line of the elements inserted into the node corresponding to the series. To book a few small depositors table first node, out of line and the first node table to merge together-- the reality is that a number of indicators provincial jurisdictions, if the number of rows and columns ranging, redundant data domain put this province has granted the use of the space. This little trick I did waste a half-day efforts, personal feeling, not merit, a lot of shortcomings,
