With the development of Internet technology, the Web-based teleoperation of mobile manipulators becomes possible. Fuzzy control is to control an object according to the experts' experiences, and its design does not depend on the mathematical model of the control object. It is suitable for the control of the mobile manipulator, which is a complex system. This paper designed a fuzzy control system of...
With the development of the information technology, database security draws more and more attention than before. It is desirable to store data in encrypted form to protect the sensitive data from various attacks. But the efficiency of DBMS will fall as the SQL clauses can not execute over the encrypted data directly. In this paper we propose a secure cipher index with great efficiency over the encrypted...
The long time and cumbersome process of spacecraft test have hampered the development of China's space industry. In order to improve the launch success rate, shorten the test time, optimize the test process, a new type of implementing project of the test and launch flow was proposed based on the theory of system engineering. In addition, this paper introduced the idea of workflow into the area of...
