The 2009 International Conference on High-Performance Networking, Computing and Communication Systems and the 2009 International Conference on Theoretical and Mathematical Foundations of Computer Science (ICHCC -ICTMF 2009) were held during December 13-14, 2009, in Sanya, Hainan Island, China. ICHCC -ICTMF 2009 was a comprehensive conference focused on the various aspects of advances in high-performance networking, computing, communication systems and mathematical foundations. The conferences provided a chance for academic and industry profe- ionals to discuss recent progress in the area of high-performance networking, com- ting, communication systems and mathematical foundations. The conferences were co-sponsored by the Intelligent Information Technology Application Research Association, Hong Kong and Wuhan Institute of Technology, China. The goal was to bring together researchers from academia and industry as well as practitioners to share ideas, problems and solutions relating to the multifaceted aspects of this area. We received 60 submissions. Every paper was reviewed by three Program C- mittee members, and 15 were selected as regular papers for ICHCC -ICTMF 2009, representing a 25% acceptance rate for regular papers. The participants of the conference had the chance to hear from renowned keynote speakers Jun Wang from The Chinese University of Hong Kong, Hong Kong and Chin-Chen Chang from Feng Chia University, Taiwan. We thank Springer, who enthusiastically supported our conference. Thanks also go to Leonie Kunz for her wonderful editorial assistance. We would also like to thank the Program Chairs, - ganization staff, and the members of the Program Committees for their hard work. | High Performance Networking Computing Communication Systems and Mathematical Foundations by Yanwen Wu, Paperback | Indigo Chapters
