It is our great pleasure to welcome you to the 13th National Computer Science and Engineering Conference; in short form, NCSEC 2009, being held in Bangkok on November 5-6, 2009. This Conference is held annually with a selective program covering all aspects of Computer Science and Engineering and its diverse applications.

The Conference is intended to involve multiple fields, including Computer System, Computer Network, Artificial Intelligence, DSP and Image Processing, Computing Technology, Computer Software and Information Technology. In the long history of NCSEC, we have provided a venue for researchers to address the new technology and findings, as well as to exchange recent research results.

We hope that the presentations, tutorials and special sessions will be valuable resources in your professional, research, and educational activities whether you are a student, a researcher, or a practicing professional.

Finally, we look forward to an exciting week of sharing ideas and visions with colleagues from all over the country. We particularly thank you for attending the Conference and being a part of this very important event.
