3D tomographic reconstruction of rainfall using satellite signals. This project aims to use the microwave communication links of low earth and/or medium earth orbit satellites to achieve three dimensional tomographic reconstruction of rainfall. The path loss of microwave signals due to rainfall, known as rain attenuation can be used to measure rain. Similar to using X-ray to carry out human-body CT scans.

Utilising the microwave signals, this project aims to investigate a high-resolution cost-effective solution to position and track un-cooperative flying objects, and expects to generate new knowledge in the area of remote sensing and to make Australia the leader in passive flying objects positioning and tracking. This should provide significant benefits, such as enabling new applications for future drone delivery systems or aerial taxi services, and benefiting the air transport industry, the defence industry, and bird conservation.Read moreRead less

Summary
Peer victimisation is a significant problem for young people in Australia and can lead to devastating long-term consequences including poor self esteem, depression and suicide. The current project aims to identify the most cost effective methods to reduce peer victimisation in schools. This will combine programs applied across the whole school with a more targeted program building resilience in vulnerable children. The results will have important implications for anti-bullying policies in school ....Peer victimisation is a significant problem for young people in Australia and can lead to devastating long-term consequences including poor self esteem, depression and suicide.

This project aims to realise real-time kinematic precise orbit and attitude determination of nano satellites. Formation flying, based on distributed miniaturised satellites such as Cubesats, is envisioned to revolutionise the way the space-science community conducts autonomous missions. The project will develop a purely kinematic concept exploiting the full capabilities of Global Navigation Satellite Systems (GNSS) carrier-phase measurements for instantaneous precise orbit and attitude determination of the Cubesats. The project will also pioneer the use of the satellite based augmentation systems (SBAS), supporting the future Australian SBAS program, and the development of integrated algorithms for space-based, Precise Point Positioning with fixed ambiguities supported by SBAS.Read moreRead less
Using Total Population Data To Describe The Characteristics Of Respiratory Infections In Order To Predict Future Epidemics And Recommend Vaccination Strategies For Western Australian Children

Summary
Respiratory infections are a major reason for children to go to hospital. I am an epidemiologist and I will be using previously collected and linked laboratory and hospital data from Western Australian children to better understand how these infections flow through the population over different seasons. I will then be able to predict future epidemics of respiratory infections and how different vaccine programs might have an impact in reducing how many children are affected by these infections.
Vaccination Timeliness In Aboriginal And Non-Aboriginal Infants: Risk Factors For Delayed Vaccination And Impact On Disease Burden—a Record Linkage Study
Funder

Funding Amount
$538,183.00
Summary
Vaccination has had a significant impact, but preventable infections continue to occur, perhaps due to delayed uptake of scheduled doses. For the first time, we will link vaccination and other health records to: provide accurate estimates of the impact of vaccination; identify reasons for delayed vaccination; and quantify the expected reduction in disease burden if vaccination timeliness was improved. The study will help determine who would benefit most from efforts to improve timeliness.
