C language programming is most one of important basic curriculums for computer curriculum teaching in science and engineering college. The traditional paper test is used in this curriculum examination. In order to meeting reformation needs of C language programming teaching, a paperless examination system based on WEB has been designed, The functions of the examination management and the curriculum...
Aims at some problems that exist in the current C language experimental problems in teaching, research and design of the C/S mode on the C language programming curriculum tests to the secondary system, better implementation of straightening out experimental teaching process, highlighting the main points of the experiment, it is able to effectively resolve problems of the experimental teaching.
The present situation of paperless examination system is introduced, this paper aims at the character of poor commonality for most of paperless examination system, a paperless examination system based on WEB has been designed, the management mode and examination mode of this system will be separated by the network frame of B/S. The design of database system uses the universal management mode of the...
Considering the inefficiency of using traditional RSA algorithm in SSL protocol at e-business area, a new e-commerce security scheme which the ECC is embed into SSL protocol has been put forward, and the test has been carried out based on the OpenSSL source codes. The result of the test indicates that the security and efficiency of e-business can be improved by adopting the new schemes.
The reliable video transmission is very challenging. Efficient coding and transmission control techniques are required to meet the needs of QoS (quality of service). RTP, a real time transmission protocol, can provide the services of video transmission control. H.264, the latest coding and compression standard from ITU-T, is currently dominating the field by offering a flexible architecture and compression...
Transporting hybrid coded video over wireless channel is very challenging. Efficient coding and compression techniques are required to meet the QoS (Quality of Service) requirements of such services. H.264, the latest coding and compression standard from ITU-T, is currently dominating the field by offering a flexible architecture and compression gain of up to 50%. In H.264, intra frame prediction...
