Acoustics of the Didjeridu. We shall undertake a comprehensive experimental and theoretical study of the acoustics of the didjeridu-lips-vocal tract system. There is very little published technical literature on the dynamic acoustics of this important and uniquely Australian instrument, whose operation is surprisingly complex. A combination of stroboscopic measurements of lip motion, acoustic and vocal tract impedance measurements, MRI imaging of the vocal tract and computer modeling will be use ....Acoustics of the Didjeridu. We shall undertake a comprehensive experimental and theoretical study of the acoustics of the didjeridu-lips-vocal tract system. There is very little published technical literature on the dynamic acoustics of this important and uniquely Australian instrument, whose operation is surprisingly complex. A combination of stroboscopic measurements of lip motion, acoustic and vocal tract impedance measurements, MRI imaging of the vocal tract and computer modeling will be used to synthesize all components of the acoustic system into one quantitative model. The expected outcome will be an understanding of this instrument of unparalleled detail.Read moreRead less
Higher Order Effects in Miniaturized Piezoelectric Devices. The national benefits of this project are: (a) We will provide opportunities to two postdoctoral researchers to pursue cutting edge research on electromagnetic radiation/scattering and self-heating phenomena in microelectronic devices involving ultrathin lossy electrodes. (b) We will provide industry-oriented research on coating and shielding problems in microelectronic devices to two postgraduate students. (c) We will team up with worl ....Higher Order Effects in Miniaturized Piezoelectric Devices. The national benefits of this project are: (a) We will provide opportunities to two postdoctoral researchers to pursue cutting edge research on electromagnetic radiation/scattering and self-heating phenomena in microelectronic devices involving ultrathin lossy electrodes. (b) We will provide industry-oriented research on coating and shielding problems in microelectronic devices to two postgraduate students. (c) We will team up with world leading industrial partners and transfer high-tech know-how to Australia. (d) The outcomes of our research will position Australia as the prime focal point for the design, modelling and simulation of microacoustic devices.Read moreRead less
