Directors Message
Research activities in the group range from investigations of power electronics and drives to control and monitoring of arc and spot welding processes. Signal processing of EEG data is a new research area.
In the area of welding, recent achievements include high speed filming of metal droplet formation and the transfer process. A model for simulating of commercial welding processes has been developed to make it more realistic. The group’s novel signal processing technology, signature image monitoring, has been commercialised by the Australian start-up company Welding Technology Innovations (WTi), which is a member of the Australian Technology Showcase. The company won the $100,000 inaugural Peter Doherty Prize for Australasian Innovation in 2003, and has recently accepted venture capital funding.
The Welding Laboratory, which is well equipped for both continuous and transient welding studies, is a member of the OzWeld Welding and Joining Technology Support Centres Network for Australian Industry. In 2002-3, one PhD student completed their thesis. Research funding has come from the Australian Research Council.
Collaboration with Dr Armin Mohamed, Director of the Comprehensive Epilepsy Service at the Royal Prince Alfred Hospital, is under way in the area of processing EEG data.
