Tri Minh Tran, graduate student in computer science in the UVM College of Engineering and Mathematical Sciences (CEMS), received one of seven "Best Paper" awards during the Second International Conference on Digital Telecommunications (ICDT) 2007 held July 1-6 in Silicon Valley.

Tran's paper, "Why Not Semijoins for Streams, When Distributed?," co-authored with Byung Suk Lee and Matthew W. Bovee, investigates methods for processing joins using sliding windows over distributed data streams. The paper focuses on query optimization techniques by adopting the notion of the semijoin — a powerful tool used in distributed database query optimization — into a distributed data stream environment.
