It takes too much time to manage the information in the traditional way and it always makes mistakes. Managing the information with database technology, designing program to access the database with Visual c tool, setting a combobox in the application UI and inquiring curriculum information by selecting the room name in the combobox. It is easy to operate the program for the staff members. The result is accurate, this way promotes the efficiency of managing information.展开更多

By comparison, the iteration method is much better because of its high accuracy, fast speed and stabilization, and it does not require calculation of the pseudoinverse of the 2acobian. Thus, this control scheme is well suited for real-time im- plementation, which is essential if the end-effector trajectory is continuously modified based on sensor＇s feedback. Finally, using VC ＋ ＋ and Microsoft foundation classes （MFC） to achieve the main machine interface. Through verification, the precision meets the requirements of general control system in real-time implementation.展开更多

Last Friday afternoon, we had a class party. At the party, we invited our English teacher, Mr. Zhang, to give us a talk on how to learn English well. Because of being good at singing, my deskmate Lin Tao sang the English song WE WISH YOU A MERRY CHRISTMAS.展开更多
