The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts have ignored wave scattering effects, and therefore do not describe the correct physics of the problem. With its combined experimental-numerical approach, the proposed fundamental studies will help to identify the potential of plate wave ultrasonic tomography for in-situ health monitoring of realistic structures and smart materials design.Read moreRead less

Inhomogeneous tissue conductivity influence on the forward and inverse electroencephalogram problems in realistic head models. The brain dysfunction indicators have been extremely difficult to obtain, largely because many disorders of higher brain function reflect abnormalities of brain function rather than apparent brain structure. The neuronal generator localization and identification in this project will provide complementary information about source and timing of neural activities sub-servin ....Inhomogeneous tissue conductivity influence on the forward and inverse electroencephalogram problems in realistic head models. The brain dysfunction indicators have been extremely difficult to obtain, largely because many disorders of higher brain function reflect abnormalities of brain function rather than apparent brain structure. The neuronal generator localization and identification in this project will provide complementary information about source and timing of neural activities sub-serving higher brain function and form sequences of spatial-temporal brain activity image. That will enable the information from MRI, which has a good spatial but poor temporal resolution, and the information from EEG, which has a high temporal resolution on the scalp, to be combined to provide clinical psychologists and brain researchers a more efficient diagnostic tool.Read moreRead less

The 'holy grail' of the mapping community is ubiquitous, cm-level accuracy positioning/orientation in all outdoor environments with a minimum installed infrastructure and operational complexity. There is currently no system able to address such needs. The integration of an Australian-developed technology within the standard GPS/inertial navigation configuration would be a truly ground-breaking achievement. This would represent a significant enhancement of Australia's capacity to develop high-value navigation products and services, and the proposed project outcomes align closely with National Research Priority 3, and address the 'Frontier Technologies and Smart Information Use' priority goals.Read moreRead less

Structural integrity monitoring, to anticipate and prevent failure, is a multi-billion dollar effort worldwide. Detailed assessment of the capability of fibre Bragg gratings to measure strain profiles along the grating length, i.e. intragrating sensing, and thereby detect structural ?hot spots? before failure is essential for effective systems. They will be used to determine strain gradients similar to those found in common problem areas, such as the tips of elliptic notches and disbonding at the ends of composite joints. Additionally, grating refractive index profiles will be characterised using imaging techniques, to assess performance and possible changes to gratings after prolonged use.Read moreRead less
