Dear Colleagues, Please accept our apologies if you receive multiple copies of this announcement. Due to numerous deadline extension requests from potential IRADSN 2009 authors, the IRADSN organizing committee has decided to extend the paper submission deadline to 11/15/2008. Please note that this is a hard deadline, so that the technical committees can perform their paper reviewing duties in a timely manner. Call for paper can be found in attachments. If you received this email in error, please forward it to the appropriate department at your institution. Please do not reply to this message. If you need to contact us please email us at iradsn09@zju.edu.cn
