Proceedings of the twenty-fifth Australasian conference on Computer science - Volume 4

These proceedings contain the papers accepted for presentation at the Twenty-Fifth Australasian Computer Science Conference (ACSC 2002), hosted by Monash University.Seventy-seven papers were submitted to the conference after a global Call For Papers was issued in April 2001. Each complete paper was fully reviewed by at least three referees from an international program committee. A total of 37 papers were accepted for presentation. Authors came from 12 countries: Argentina, Australia, Brazil, Canada, China, Finland, Germany, Japan, Korea, New Zealand, United Kingdom, United States of America.Each year the Australian Computer Science Association awards the Distinguished Australian Ph.D. Dissertation in Computer Science for the best Ph.D. thesis completed in the previous year. The award for the best Ph.D. thesis completed in 2000 went to Dr. Johanna Wenny Rahayu for his thesis entitled Object-Relational Transformation Methodology completed at the La Trobe University under the guidance of Dr. Elizabeth Chang, and Prof. Tharam Dillon.In 1996, the Association began presenting awards for the best student paper at ACSC. In 2002 this was extended to cover the best student paper submitted across all of the conferences comprising the Australasian Computer Science Week. The student had to be the major author of the paper to be eligible. The prize for best student paper in 2002 is awarded to Trent W. Lewis from the Flinders University of South Australia for the paper Audio-Visual Speech Recognition Using Red Exclusion and Neural Networks, co-authored with his supervisor Assoc. Prof. David M.W. Powers. This award, and the award for the best Australian Ph.D. dissertation in 2001, will be presented at the conference.
