3rd NGS Student Symposium February 28, 2011 Venue supported by: Shaw Foundation Alumni House Organizing Commitee Lin Aigu Priscilla Ang Abdul Qader Al-Aidaroos Chung Kai Sheng, Bevan Daniel Dahlmeier Hao Hanfang Christine Koo Lim Jing Yan Lin Guan Hui Alvin Loo Sampath Jeewantha Wijesinghe Wu Yongzhi Daniel Yim Zhang Xuan Description of cover logo As a computational linguist, I am interested in the application of artificial intelligence to human language. For my logo submission for this year's NGS student symposium, I used a webservice called \wordle" (www.wordle.net) to automatically create a word cloud from the content of the NGS website. Notice how the algorithm automatically indentifies the important words that decribe NGS, like Research, Sciences, Engineering, and of course the goal of every student: Graduate ;) Daniel Dahlmeier Venue: Auditorium (2nd Storey) Shaw Foundation Alumni House 1 Kent Ridge Drive Singapore 119244 Welcome NGS Scholars' Alliance warmly welcomes you to the 3rd NGS Student Sym- posium held in the Shaw Foundation Alumni House. NGS Scholars' Alliance is the official student body for NGS students. It was established in December 2005 to serve as a platform for intellectual exchange and interaction among all NGS scholars. NGS Student Symposium is an annual conference organised by the NGS Scholars' Alliance. The aims of the symposium are to foster effective communication between NGS students and their supervisors, give NGS students an opportunity to showcase their research findings and promote interaction be- tween NGS students and renowned scientists of different fields. Since its inception in 2008, the NGS Student Symposium has grown from strength to strength. This year, we received a total number of 78 abstracts submitted for oral and poster presentations. This would not have been possible without the participation of all NGS students who have submitted abstracts for either oral or poster presentations and the organizing committee would like to thank all participants for their efforts. To enhance technical information exchange among researchers of similar fields, we have segmented the symposium into two sessions; First, the Phys- ical Sciences and Engineering and second, the Chemistry, Biology and Medical Sciences. This year, it is our great privilege to have with us, Professor Anthony Zee and Professor Ding Jeak Ling, as our honorary invited speakers. We would like to take this opportunity to extend our heartfelt gratitude to the NUS Office of Alumni Relations for kind sponsorship of this venue. In addition, we would like to thank Ms. Ivy Wee, Ms. Irene Chuan and Ms. Angela Poon for their constant support and invaluable advice. All in all, this symposium is dedicated to encourage networking and scientific exchange among research students and professors. It would have been impossible without your contribution, feedback and constructive suggestions. If you have any suggestion or a keen interest in helping NGS organize quality meetings such as this, please do not hesitate to contact us or Ms. Ivy Wee ([email protected]). With this, we thank all of you for your participation and have a fruitful conference!
