This project aims to advance fundamental research in active noise control over spatial regions. It has a broad range of industry applications, such as eliminating road and engine noise for multiple passengers inside car/airplane cabins, and creating individual quiet zones in a public environment. It will focus on developing new theories and techniques to generate multiple quiet zones in indoor/outdoor noisy environments with performance prediction, robust control, and effective implementation. In many practical applications, especially in consumer electronics and medical instruments, the creation of quiet zones is desirable so that in a shared environment people can have their own audio space without physical isolation or using headphones, creating a healthy living and working environment.Read moreRead less

Nanocavities and Nanoparticles in Silicon-based Materials Tailored by Ion Implantation. Nanometre sized crystals embedded in different host materials can exhibit novel optical behaviour, including light emission. However, the optical properties depend critically on the ability to tailor the size and size distribution of such nanocrystal inclusions, parameters that are extremely difficult to control. This project is based on our previous discovery that small holes of controlled size and distri ....Nanocavities and Nanoparticles in Silicon-based Materials Tailored by Ion Implantation. Nanometre sized crystals embedded in different host materials can exhibit novel optical behaviour, including light emission. However, the optical properties depend critically on the ability to tailor the size and size distribution of such nanocrystal inclusions, parameters that are extremely difficult to control. This project is based on our previous discovery that small holes of controlled size and distribution can be formed in silicon by ion irradiation and that such cavities can be filled with fast diffusing elemental species. We intend to explore this novel concept to tailor the size of desired nanocrystals in silicon-based materials for optoelectronics applications.Read moreRead less

In partnership with a local computer company this project will develop cost effective cluster computing solutions assembled from off-the-shelf parts for $50,000-$200,000. This price range is currently relatively poorly serviced by the multinational computer vendors, who tend to focus on the high density compute systems necessary for very large cluster systems. As a consequence the development of high performance computing in Australia has been somewhat stifled compared to the US or UK, where there exist small niche companies servicing this market sector. This project aims to change this, developing affordable high performance cluster computing systems for the Australian market place and beyond.Read moreRead less
