Copper chrome arsenic (CCA) timber is a major waste that is currently being stockpiled around Australia. The strict environmental restrictions on their disposal means that this stockpile will increase annually. This project looks at optimising the choice of acids for leaching of CCA from the timber, an understanding of the rate processes and chemical equilibrium that determine the extraction efficiency of those elements, and the recovery of the copper, chromium and arsenic from the waste stream.

Gasdynamic lasers create optical gain from the rapid expansion of gas through a nozzle. This can produce very high peak laser powers, and makes such lasers potentially useful in a range of applications. The efficiency of the laser is determined by the ability to create and maintain a nonequilibrium distribution of vibrational energy within such a nozzle. One effective way of driving the expanding flow is by providing elevated energy with combustion, however, some product species such as water vapour can impair the effectiveness of the rapid flow expansion in creating a population inversi
Improving forecasts of space weather has been identified as a major goal for the space community. Space weather has substantial effects on space and ground operations, yet accurate forecast lead times are typically only a few hours to days at most. The goal of this PhD is to improve our understanding and forecasting capability of space weather through physics-based models and/or machine learning.
Modularity as a system property has many benefits for different lifecycle stages of a system. This project is an investigation of a complete set of these benefits as well as a search for optimum formation of the modules for maximum benefit to all or some the identified benefits, at early design stages.
This PhD work is a part of the project to develop high bandwidth control methods and advanced dynamic modelling for Rotorcraft Unmanned Aerial Vehicles (RUAVs). This will enable new roles such as the precision landing of RUAVs to the moving deck of a ship in rough seas. This and numerous other potential RUAV tasks are presently limited by the simple controllers used for such a responsive dynamic system.
In contemporary enterprises, single project settings are rare today. Hence, issues involving the simultaneous management of multiple projects (or portfolio of projects) have become more prevalent. Up to 90 % of all projects worldwide are executed in a multi-project context (i.e., portfolio of projects). This portfolio of projects (POP) is considered as the simultaneous scheduling of two or more projects which demand the same scarce resources.
Learning and teaching fully online is a challenging task as it requires maximum engagement with fellow students and the course convenor to create a sense of online community among distance learners.
Gas turbines bend when the are turned off, due to differential cooling. This thermal bow can damage the engines if they are restarted too early, which will reduce their fatigue life and can ultimately destroy them in flight. It is therefore crucial to the safe operation of current and future engines that we improve our abilities to predict this bow and design it out.
