New quantum and robust control theory with applications to quantum optics. The application of quantum mechanics to the creation of quantum technology promises to be one of the most exciting technological developments of this century. Possible applications of quantum technologies include vastly improved sensors to search for minerals or gravity waves, secure quantum cryptography, and quantum computing.

The application of quantum mechanics to the creation of quantum technology promises to be one of the most exciting technological developments of this century. Possible applications of quantum technologies include vastly improved sensors to search for minerals or gravity waves, secure quantum cryptography, and quantum computing. Quantum feedback control is a key tool in quantum technology. This project will lay the foundations of systematic theories of robust, coherent and nonlinear quantum feedback control and lead to advances in the control of highly resonant systems which underlie experimental quantum and nano technology. This will enable Australia to reap great benefits as this new technological area emerges.Read moreRead less
Matched experimental observation and finite-element simulation of flow-induced oscillations in uniform and tapered-stiffness collapsible tubes. Flexible tubes that can be flattened are widespread in the body and can act to limit flow-rate. Limitation is usually associated with spontaneous oscillation (repetitive opening and closing). There are many candidate explanations, but none has been shown to correspond with a given experiment. Through computer models and matched experiments on this couple ....Matched experimental observation and finite-element simulation of flow-induced oscillations in uniform and tapered-stiffness collapsible tubes. Flexible tubes that can be flattened are widespread in the body and can act to limit flow-rate. Limitation is usually associated with spontaneous oscillation (repetitive opening and closing). There are many candidate explanations, but none has been shown to correspond with a given experiment. Through computer models and matched experiments on this coupled system (the fluid flow interacts with the tube shape), we seek to demonstrate for the first time that a given theory/computer model encompasses the physics controlling a given observed oscillation. The solution will find application in other flexible-structure design problems in engineering, and also potentially in medicine.Read moreRead less

Flow-induced oscillation in flexible tubes: experimental and numerical investigation of mechanism and onset. We seek to understand when instability arises in flow over very deformable structures. This will help us to design highly flexible structures specifically either to avoid the danger of flow-induced oscillations, which may be damaging (cardiac surgery, sails, parachutes), or in other circumstances to take advantage of them as an innovative way involving no sliding-parts mechanisms to crea ....Flow-induced oscillation in flexible tubes: experimental and numerical investigation of mechanism and onset. We seek to understand when instability arises in flow over very deformable structures. This will help us to design highly flexible structures specifically either to avoid the danger of flow-induced oscillations, which may be damaging (cardiac surgery, sails, parachutes), or in other circumstances to take advantage of them as an innovative way involving no sliding-parts mechanisms to create vibration, or flow pulsation, or sound, or motion (as in swimming-pool cleaners). Confidence in designing with highly flexible tubes will allow minimal resource consumption in manufacture of products to transport fluids, and will allow design use of the flow limitation property, whereby such a tube can control flow-rate.Read moreRead less

Summary
Network on Control, Dynamics and Systems (NCDS). Control systems theory provides principles and methods for design of complex engineering systems that automatically maintain desired performance despite changes in their environment (e.g. autopilot in an aircraft). This field is facing many new exciting challenges at the dawn of new millenium, such as design of complex engineering systems in possibly networked, asynchronous and distributed environments.

Control systems theory provides principles and methods for design of complex engineering systems that automatically maintain desired performance despite changes in their environment (e.g. autopilot in an aircraft). This field is facing many new exciting challenges at the dawn of new millenium, such as design of complex engineering systems in possibly networked, asynchronous and distributed environments. The network will play a major role in addressing these challenges by providing a national research focus, facilitating collaboration and the sharing of people and ideas. By delivering a National Graduate School, the network will enhance learning conditions for graduate students. Moreover, it will provide an important catalyst between Australian universities and industry. This initiative will be essential in assessing the present state of control research in Australia and drafting a detailed plan for the network's leading research role in the future.

Nonlinear Dynamics of Pulse Coupled Oscillators. A mathematical model of the heart pacemaker system will be created, based on simple interacting units. These units have been shown to be good models of physiological information e.g. the discrimination of different influences on heart rate. We will firstly look at the interaction of the units in simple combinations and then tune the model to mimic the behaviour of the cardiac pacemaker.

We will firstly look at the interaction of the units in simple combinations and then tune the model to mimic the behaviour of the cardiac pacemaker.
Potential benefits may arise from elucidating the mechanisms underlying arrhythmias which contribute to ?sudden cardiac death? in young men, and suggesting strategies for artificial pacemakers to effectively arrest abnormal rhythms before they convert to potentially fatal fibrillation.Read moreRead less
Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science.

For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less
