Data exfiltration is a serious threat as highlighted in recent leakage of sensitive data that resulted in huge economic losses as well as unprecedented breaches of national security. The aim of this project is to develop a comprehensive and robust solution for detection and prevention of sensitive data exfiltration attempts by malware and unauthorised human users. Expected outcomes include scalable monitoring methods and efficient algorithms that will be able to prevent real-time exfiltration and identify previously undetected exfiltration of sensitive data. This should provide significant benefits to governments, defence networks as well as businesses and health sectors, as it will protect them from sophisticated cyber attacks.

Theoretical and experimental study of elastic properties of porous media permeated by aligned fractures. The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretic ....Theoretical and experimental study of elastic properties of porous media permeated by aligned fractures. The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretical model will be verified using numerical simulations and ultrasonic measurements made on synthetic porous and fractured samples. The results are expected to benefit seismic exploration and the production of oil and gas in fractured reservoirs.Read moreRead less
Blind separation of mutually correlated sources. This project is aimed at developing novel techniques for blind separation of mutually correlated sources. The expected outcomes will significantly advance the theory of blind source separation and improve the performance of important practical systems, such as densely deployed sensor networks and wireless video surveillance systems.
WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier ....WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier and to provide maximum sound absorption at the frequencies of concern, and thus to minimize the contribution due to the reflection. The aim is to develop a theoretical and experimental model for the physical understanding and optimal design of the WTB. Outcomes include a new generation of noise barriers that are potentially light-weighted, fiberless and with higher insertion loss.Read moreRead less
Seismic response of partially saturated petroleum reservoir zones: towards quantitative recovery monitoring. In most Australian reservoirs less than 50% of the original oil in place is recovered. A major factor that contributes to low recovery rates is bypassed oil/gas. Even a small, 1% improvement in recovery is of substantial economic significance. The proposed project aims to develop quantitative models for reservoir monitoring of zones with bypassed hydrocarbons using time-lapse (4D) seismic ....Seismic response of partially saturated petroleum reservoir zones: towards quantitative recovery monitoring. In most Australian reservoirs less than 50% of the original oil in place is recovered. A major factor that contributes to low recovery rates is bypassed oil/gas. Even a small, 1% improvement in recovery is of substantial economic significance. The proposed project aims to develop quantitative models for reservoir monitoring of zones with bypassed hydrocarbons using time-lapse (4D) seismic measurements, and thus to improve the hydrocarbon recovery factors. Developing these models will be a cutting edge research achievement, which will make a significant contribution to the knowledge base of the discipline and advance the international reputation of Australian science.Read moreRead less

We propose to develop theoretical models of seismic attenuation and dispersion in hydrocarbon reservoirs, and a new method for experimental testing of these models. These models will provide new information to substantially improve characterisation of hydrocarbon reservoirs from geophysical data. The results will help optimise exploration and improve oil and gas recovery through development of new technologies for quantitative reservoir characterisation in Australian basins. This research will enhance Australian competitiveness in basic and applied geophysical research, and will benefit the Australian geophysical industry as a provider of advanced geophysical technologies for oil exploration and production.Read moreRead less
Measurement of the spatial distribution of temperature and velocity in lakes using Acoustic Tomography. This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity.

This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity. The challenges with lake acoustic tomography are the accuracy required in the travel time measurements over shorter distances, acoustic losses due to reflections and ensuring enough rays travel through the thermocline, the region of greatest interest in lakes. A pilot experiment in a deep lake will investigate the quality of travel time measurements computed from rays travelling through the thermocline of a strongly stratified lake. This has wide applications for the water quality management of lakes and reservoirs.Read moreRead less

Acoustic observation of Antarctic ice rifting and calving events using remote hydroacoustic listening stations. The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent.

The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level around the world, with devastating effects on the continental coasts and low-lying islands. The method of remote acoustic observations investigated in this project is a new approach to the problem of creating an efficient and cost effective system to monitor rifting and calving of the Antarctic ice shelves.
