学生成绩统计查询系统，有学生、课程、统计、查询、系统说明五个菜单，单击不同的菜单会有子菜单出现。很好的实现管理学生成绩问题。(Student performance statistics query system, students, curriculum, statistics, query, the system shows five menu, click a different menu sub-menu will appear. Achieve good management of student achievement issues.)

This is the program for 2D ADI FDTD method introduced by Namiki. This works fine with non-uniform cell, but for uniform cells, the program is not correct.

This book is a good for the beginner in embedded system

在电网电压频率波动或者三相不平衡的情况下,硬件锁相很难准确检测到基波正序的相位。在结合PWM整流器空间矢量解耦控制算法的基础上,将软件锁相环技术应用在PWM整流器控制系统中,并用仿真和实验验证了该方案的可行性。实验结果表明,该方案解决了电网电压频率波动及三相不平衡时的相位同步等问题,并在工程上具有一定参考价值。(Frequency or voltage fluctuations in three-phase unbalanced case, the hardware lock is difficult to accurately detect the fundamental positive sequence phase. In the space vector PWM rectifier with decoupling control algorithm based on the software used in the PWM rectifier PLL control system, and use simulation and experimental verification of the feasibility. Experimental results show that the solutions to address the voltage and frequency fluctuations of the phase unbalanced three-phase synchronization issues, and the project has a certain reference value.)
