Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics. Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repa ....Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics. Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repairs. Towards this end, this project will develop an innovative structural health monitoring system to monitor and maintain the structural health of our bridges. The project outcomes will have immediate applications in Australia and overseas with economic and social benefits to the community.Read moreRead less
Advanced Future Automotive Electrical Machines based on Amorphous Iron. Electric machines consume about 70% of all electrical energy generated. Electric machines constructed from a promising magnetic material called amorphous iron can be much more efficient than conventional designs, hence saving energy. Amorphous iron is normally difficult to cut accurately into the shapes required in electric machines. We propose to design and construct high-efficiency permanent magnet machines based on amorp ....Advanced Future Automotive Electrical Machines based on Amorphous Iron. Electric machines consume about 70% of all electrical energy generated. Electric machines constructed from a promising magnetic material called amorphous iron can be much more efficient than conventional designs, hence saving energy. Amorphous iron is normally difficult to cut accurately into the shapes required in electric machines. We propose to design and construct high-efficiency permanent magnet machines based on amorphous iron for automotive applications, which will be cut using an innovative Australian waterjet cutting technique. The key challenges are to optimise the machine design for commercial production given the capabilities and limitations of the material and the new cutting process.Read moreRead less

Observer design for singularly perturbed systems. This project aims to provide a framework for observer design for singularly perturbed systems, analyse performance/robustness of such designs and apply it to engineering problems. Estimating unmeasured physical variables from available measurements is essential in engineering and science, but is hard when the system exhibits multiple time scales. This is common as dynamics occurring on much faster time scales age engineered systems’ physical prop ....Observer design for singularly perturbed systems. This project aims to provide a framework for observer design for singularly perturbed systems, analyse performance/robustness of such designs and apply it to engineering problems. Estimating unmeasured physical variables from available measurements is essential in engineering and science, but is hard when the system exhibits multiple time scales. This is common as dynamics occurring on much faster time scales age engineered systems’ physical properties, but tools to deal with these systems do not exist. This project aims to provide the fundamental science to estimate systems exhibiting multiple time scales. These results are expected to improve condition monitoring in mechanical, electrical and power systems.Read moreRead less

Australia is a sparsely populated country with a number of unique airspace features. This project will investigate novel vision-based collision warning systems that can improve safety for piloted aircraft and also help achieve integration of UASs (Uninhabited Aerial Systems) into national airspace. The benefits of UAS technologies are particularly relevant to Australia, as governments and industry struggle to cope with providing equivalent levels of service to remote communities over vast distances (or border protection of vast regions). The population base of Australia requires that cost-effective solutions are sought to meet this end. Read moreRead less
