New multiplexed optical read-out technologies for micromachined cantilever sensor arrays. Passive sensing of chemical and biological agents is an essential capability in fields as diverse as national security, agriculture, mining and medicine. In many cases, generic sensing (e.g. are there pesticides present) as well as specific sensing (which pesticide) are both important. While sensors based on micro-electromechanical systems (MEMS) have shown extremely high performance at low cost, they have ....New multiplexed optical read-out technologies for micromachined cantilever sensor arrays. Passive sensing of chemical and biological agents is an essential capability in fields as diverse as national security, agriculture, mining and medicine. In many cases, generic sensing (e.g. are there pesticides present) as well as specific sensing (which pesticide) are both important. While sensors based on micro-electromechanical systems (MEMS) have shown extremely high performance at low cost, they have been limited to detection of a specific substance. Success in this project will make low cost generic MEMS-based sensors a reality, allowing, for the first time, wide-spread use of sensitive sensing systems in applications such as farming, container transport security, general medical practice and national security.Read moreRead less

Direct application of the techniques developed in this study to a pilot case study, could be used as a benchmark to show the potential benefits that can be gained through smart information use and data management.Read moreRead less
Rapid structural condition assessment using adaptive model updating. The proposed project has potential to significantly enhance the accuracy with which the condition (and hence load bearing capacity) of existing infrastructure can be determined.

The proposed project has potential to significantly enhance the accuracy with which the condition (and hence load bearing capacity) of existing infrastructure can be determined. By providing a technique of model updating that can be applied effectively in real time, location of damage will be able to be determined accurately. Economic benefits will be reaped, both through saving infrastructure from demolition where the condition is found to be adequate, and by replacing or repairing inadequate structures before costly failure occurs. This is particularly important as much of Australia's infrastructure is aging, and unnecessary periodic replacement of infrastructure is not sustainable.Read moreRead less
Blast Damage and Fragmentation Prediction for Occupants and Structure Protection. Protecting infrastructures against blast loads from terrorist bombing or accidental explosion is a challenge. Researchers have been working on developing a numerical model, but the progress is slow owing to difficulties in modelling nonlinear and high strain rate damage process.

These have been demonstrated not necessarily yielding accur ....Blast Damage and Fragmentation Prediction for Occupants and Structure Protection. Protecting infrastructures against blast loads from terrorist bombing or accidental explosion is a challenge. Researchers have been working on developing a numerical model, but the progress is slow owing to difficulties in modelling nonlinear and high strain rate damage process. Most blast effect assessment is based on empirical relations from blast tests. These have been demonstrated not necessarily yielding accurate prediction owing to variations of structural properties from the test model. A reliable numerical model is therefore important. It will result in big savings from blast tests, and better prediction of blast effects for structure and occupant protection. It will have applications in civil, mining and defence engineering.

Understanding structural response to explosive loads is essential to protect critical infrastructure against terrorist bombing or industrial explosions. Current practice in analysis and design of structures to withstand explosive loads uses either empirical methods or a simplified structure model. In many cases, engineers need to know the structure response in more detail in order to protect the structure and plan evacuation procedures. This project will study the response and damage mechanism of structures to explosive loads, and develop a numerical model to predict structural response and damage. It will have immediate and wide-ranging applications in defence, construction and mining engineering.Read moreRead less

Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods. Vibration-based methods are very sensitive to noise in vibration measurement and error in finite element modelling. This project will study the effects of measurement noises and finite element model errors on bridge condition assessment, and develop improved techniques for predicting load carrying capacities of bridges. The technique developed will be applied to Main Roads WA bridges, will also be applicable to the assessment of other types of structures.Read moreRead less
