Plate Wave Tomography for Reconstruction of Laminar Defects. 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.

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

This new system will incorporate a novel optical sensor, which will be developed in this project, and a new optical corrector being developed at the University of Durham. Currently available astronomical adaptive-optics systems have produced excellent results but are expensive and complicated. A low-cost alternative will dramatically increase the use of adaptive optics in industrial, environmental and medical applications. The compensation of distortions in low-cost optical atmospheric sensors will be demonstrated.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
Microwave System for Early Breast Cancer Detection Employing Ultra Wideband Conformal Array Antenna. Breast cancer is the most common cancer diagnosed in women in various parts of the world. Currently the primary method for breast screening is X-ray mammography and in rare cases Magnetic Resonance Imaging.

The proposed Facility comprises a Global Navigation Satellite System (GNSS) RF Signal Simulator which allows laboratory testing of new signal tracking and navigation solution algorithms, under different scenarios. Simulation of the operation of current and future GPS satellites, and of the new European GNSS "Galileo", is vital for testing new receiver designs. For example, the Facility could be programmed to generate a GPS satellite signal with user-selectable physical variations in the signal path, including the presence of RF jamming sources, high atmospheric disturbances, diffraction effects and multipath. As many of the signal variations are rare and/or unpredictable, the Signal Simulator is the only means to carry out such tests.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
