该项目的开发是在学生课程日益增多的压力下设计且用来解决选课的烦恼，从而达到简化管理人员工作的目的。
选课系统数据库管理人员和在校学生各作为单独的一类用户,管理人员主要通过该系统对学生的选课情况进行查询以及对学校课程进行管理。
软件开发的意图为便于学校的管理,方便学生的选课.如学生可以查询，修改，删除自己所选课程，管理人员可对课程进行查询，修改，删除等工作。
The project was developed courses in the students under the pressure of an increasing number of design courses and to address anxieties, thereby simplifying the management staff to achieve the purpose. Elective system, database management staff and students at school each as a separate category of users, managers, mainly through the system of selection of students to conduct inquiries and to manage the school curriculum. The intention of software development in order to facilitate the management of schools to enable the students to the course. If students can learn about, modify, delete their selected courses, course managers can query, modify, delete and so on. (2008-05-20, Java, 226KB, 下载14次)

固定资产管理系统
采用多层开发模式，WorkFlow开发的固定资产管理系统
系统管理
1.角色管理
角色包括采购员( 即管理员)、经理、校长、董事长这4种(分别用1,2,3,4表示)
1-管理员拥有除了审批以外的所有权限
2-经理负责员工的申请资产。
3-校长负责经理的申请
4-董事长负责校长的申请
2.用户管理
2-基础数据
1-类别管理
例如电脑整机下面有子类别笔记本,笔记下还有子类
2-存放地点
比如分为一校区、二校区、河西培训中心等，而一校区又分为一楼仓库、二楼仓库等。
3-使用地点
使用地点也像上面一样
3.资产管理
1-资产入库
资产入库就是将现有的资产添加进来。包括资产编号，名称，类别，购买日期，型号规格，单位，数量，单价等。
2-购买资产
资产购买就是后勤申请采购->校长审批->董事长审批-> 入库登记
3-领用资产
领用资产先是查看是否存在，如果存在,再通过审批，再添加一条领用记录，同时减少这个资产的数量。

[数据结构] elevator-simulation
电梯模拟，模拟某校九层教学楼的电梯系统。该楼有一个自动电梯，能在每层停留。九个楼层由下至上依次称为地下层、第一层、第二层、……第八层，其中第一层是大楼的进出层，即是电梯的“本垒层”，电梯“空闲”时，将来到该层候命。
乘客可随机地进出于任何层。对每个人来说，他有一个能容忍的最长等待时间，一旦等候电梯时间过长，他将放弃。
模拟时钟从0开始，时间单位为0.1秒。人和电梯的各种动作均要消耗一定的时间单位（简记为t），比如：有人进出时，电梯每隔40t测试一次，若无人进出，则关门；关门和开门各需要20t；每个人进出电梯均需要25t；如果电梯在某层静止时间超过300t，则驶回1层侯命。

Passengers can randomly access any layer. For everyone, he can tolerate a maximum waiting time, waiting for the elevator when the time is too long, he will give up.
Analog clock starts from 0, the time unit is 0.1 seconds. And lift a variety of actions have to consume a certain unit of time (abbreviated as t), for example: it was out of the elevator 40t test every time, without the movement of people, then closed close and open the door of the need to 20t each personal and out of elevators require 25t if the elevator stationary at a level more than 300t, then drove back a layer ready to go.

NetTalk是一个适用于局域网和因特网的可视软件
一． 开发环境
Windows2000 Server & Visual C++6.0 & SDK
+自开发的CWndX类库(相当于简化的MFC涉及窗口的部分)
二． 支持环境
Windows98/ME/2000/XP
三． 所涉及协议和标准
网络传输采用UDP协议（被封装成支持超时重传等机制的UDP类），音频压缩采用G.729标准，视频压缩采用H.263标准
四． 性能参数
以音频帧为基准，每帧音频数据有２４０个采样点，时间为２４０＊１０００／８０００＝３０ms，８０００为音频的采样率。
数据接收端队列缓冲延迟：３０＊3＝90ms
数据发送端录音延迟：30ms
数据压缩解压耗时：<40ms
网络延迟：<100ms（我想校网情况应该不错 ）
总延迟：<260ms
根据VOIP标准，总延迟<300ms是人可以接受的，以上计算是保守的，实际情况可能会好得多。
