Description: 用Eclipse＋JDK开发的课表生成系统
作到教师与教室不会冲突
教室要得到充分的利用
一位教师不能在同一时间上两门及以上课程，或同时出现在多个教室
课程尽可能按时间均匀分布，不出现课程集中在某一时间段现象

Description: In the future, power distribution systems now controlled by large power generators will be
enhanced with more distributed energy resource (DER) architectures in which the demarcations
between providers and users of power are less restrictive. Industry is concerned about how
existing electric power systems (EPSs) can accommodate these changes because they will affect the economics and performance of power delivery. One key area of concern is the technical details of interconnecting distributed generation (DG) with the EPS. Platform: |

Description: matlab实验 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。
如果作2或4次多项式拟合，结果如何？

Description: 优秀论文配套源码。分布式电源的接入使得配电系统从放射状无源网络变为分布有中小型电源的有源网络。带来了使单向流动的电流方向具有了不确定性等等问题，使得配电系统的控制和管理变得更加复杂。但同时，分布式电源又具有提高电网可靠性，绿色节能，等等优点，所以为更好的利用分布式电源为人类造福，我们必须对其进行研究与分析。
本文采取通过利用仿真软件Matlab编写计算潮流程序模拟分布式电源接入配电网的模型进行潮流计算的方法对分布式电源的稳态影响进行探索与分析。
选取了34节点的配电网网络模型，通过对单个以及多个分布式电源的接入位置以及容量的不同情况对34节点配电网的网损以及节点电压状况进行了分析。
-The distributed generation access to distribution system makes passive radial distribution network to active medium-sized power distribution network. It brings uncertainty to one-way direction power flow, etc., and it makes the control and management of the distribution system more complicated. Otherwise, it can bring a lot of benefits, such as more reliable, and it is green power. The distributed generation should be better known , so we can benefits more.
So the program called Matlab was used to compile a program to solve the power flow problem. By this program, we can text which factor can influence the distributed generation’s access to the distribution system.
The IEEE 34 Node model was chosen to be discussed how different factors can influence the power quality. This article analyzes distributed generation’s influence to the distribution system of energy lost and voltage level.
