This project aims to develop a comprehensive understanding of granular mixing mechanics in bladed mixers. The study will be carried out by means of newly developed advanced numerical and experimental techniques to generate particle scale information. The flow and mixing behaviour of particles under different conditions will be analysed at both micro- and macro-scopic levels. The research outcomes such as predictive equations will be tested by simulating and analysing complicated industrial mixing processes; modelling to improve granulation and breakage will be targets. It will significantly improve the design, optimisation and control of mixing processes that are widely used in many industries.Read moreRead less
Particle scale studies of powder mixing in bladed mixers. Powder handling and processing are widely used in both conventional and modern industries but rarely reach more than 60% of design capacity because of poor fundamental understanding. Such operations are important to Australia in view of the heavy dependence on raw materials processing (about 40% of the GNP). This project will tackle the core problems in powder mixing which is a key operation in many industries. Application of the research ....Particle scale studies of powder mixing in bladed mixers. Powder handling and processing are widely used in both conventional and modern industries but rarely reach more than 60% of design capacity because of poor fundamental understanding. Such operations are important to Australia in view of the heavy dependence on raw materials processing (about 40% of the GNP). This project will tackle the core problems in powder mixing which is a key operation in many industries. Application of the research outcomes can lead to better process or product control, a decrease in energy consumption and an improvement in productivity, which is very helpful to maintaining Australia's leading position in resource, energy, process and allied industries.Read moreRead less
Multi-scale Process Modelling for Intelligent Control. Processing and manufacturing systems are inherently multi-scale in their behaviour. From the molecular scale to the enterprise-wide scale. This and other attributes of the individual models create difficulties in the design and control of such systems. This project will develop suitable multi-scale measures (metrics) for process models based on an object oriented assumption based modelling language. It will lead to enhanced intelligent contr ....Multi-scale Process Modelling for Intelligent Control. Processing and manufacturing systems are inherently multi-scale in their behaviour.

Web service composition technology promises to revolutionise the way in which organisations interact over the Web. However existing environments for the composition of Web services are too complex to use and are usually intended for experienced application developers as they rely either on scripting languages, or on a process-modelling notations intended to be used by IT experts. However, the need for customised composition of Web services is likely to emanate from non IT-experts.
The project aims at designing, implementing, and evaluating an environment for the specification and execution of composite Web services by non-expert.Read moreRead less

organizations to form alliances by connecting their applications and systems, in order to offer ``one-stops shops'' for their customers. However, several important issues (e.g., security and privacy) need to be properly addressed before Web services technology meets the requirements of critical applications such as e-goverment. This project aims at providing privacy preserving Web services composition techniques. The anticipated outcome of this project is a service composition framework that provides seamless interoperability between different Web services without violiating citizens and organisations privacy.Read moreRead less
A new erasure resilient technique for encoding internet packets. Efficient internet communication tolerates losing some packets sent across the web by sending a bit more information than is required. Any holes in the transmission can be repaired using the redundant data. We propose a new transmission protocol that is much simpler to encode and repairs broken messages faster. This new approach, based on sending data plus summed versions of itself, has generic applicability across all packet switc ....A new erasure resilient technique for encoding internet packets.

Thanks to the proliferation of the Internet and web technologies, it is now possible to exploit the power of these technologies to facilitate the cooperation of teams of workers across distances. Such virtual teams and virtual enterprises are expected to overcome many problems associated in the modern service industry spanning continents. Countries (such as Australia) that are located far from the main markets (e,g, Europe and North America) stand to gain substantially from successful deployment of such virtual organisations. Researchers from UNSW and LORIA France have been working together on the development of cooperative management models for virtual enterprises. This application seeks funding for the travel of researchers across these countries to facilitate this research.Read moreRead less

Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with robust fluid flow simulations. The method can potentially be utilized to predict trends such as filtration behaviour of materials under different states of compression. This offers significant benefits in formulating the design of flocculated systems pertinent to a number of industrial sectors wishing to design optimum solid-liquid separation processes.Read moreRead less

This project proposes to study two extensions to the Page rank equation which is one of the theoretical underpinning of Google's web page scoring engine. In particular, we wish to explore ways to combine page connectivity and page characteristics in the scoring of web pages. This will be the first time a rational way is proposed for combining these two factors. The expected outcome will be a deeper understanding on how these two factors affect the scores of a web page in a search engine, and hence how they affect the visibility of the page in response to a query.
