Surface Modification of Spray-Dried Powders By Surface-Active Proteins. Internal wall deposits in spray dryers lead to product degradation and pose fire hazards. This situation has limited the manufacturing of high value bio-food powders by the Australian bio-food and dairy industry, which exports 13% of the milk powder in the world. The specific economic benefits to Australia from this project arise from innovative surface modification of powder particles by proteins, development of scientific ....Surface Modification of Spray-Dried Powders By Surface-Active Proteins. Internal wall deposits in spray dryers lead to product degradation and pose fire hazards. This situation has limited the manufacturing of high value bio-food powders by the Australian bio-food and dairy industry, which exports 13% of the milk powder in the world. The specific economic benefits to Australia from this project arise from innovative surface modification of powder particles by proteins, development of scientific instruments and predictive tools based on Computational Fluid Dynamics (CFD). These outcomes will lead to production of free flowing powders from bio-food materials.Read moreRead less
Mullins-type effects in soft filled viscoelastic solids. Bread dough is made in vast quantities daily, and improvements in processing,especially sheet rolling,are needed,and to enable this we propose to create a novel mathematical description of the material. Also, wheat breeding cycles can be drastically shortened by using knowledge of dough rheology, since baking quality is closely linked to rheology. The mathematical framework can then be applied to other filled viscoelastic systems, and work ....Mullins-type effects in soft filled viscoelastic solids.

Also, wheat breeding cycles can be drastically shortened by using knowledge of dough rheology, since baking quality is closely linked to rheology. The mathematical framework can then be applied to other filled viscoelastic systems, and work on liquid crystals may be used to develop artificial muscle material, once their rheological description and behaviour are known.Read moreRead less
Doped Nanocrystalline TiO2 - Synthesis and application for photoreduction reactions. The proposed project aims to develop a novel photocatalyst, prepared by doping nanocrystalline TiO2 with noble metals, for use in photoreduction reactions. The ability of this photocatalyst to reduce heavy metals and its potential to generate H2 in an inert environment will be explored. The project will benefit the environment by removing toxic compounds from polluted wastewaters as well as potentially generatin ....Doped Nanocrystalline TiO2 - Synthesis and application for photoreduction reactions. The proposed project aims to develop a novel photocatalyst, prepared by doping nanocrystalline TiO2 with noble metals, for use in photoreduction reactions. The ability of this photocatalyst to reduce heavy metals and its potential to generate H2 in an inert environment will be explored. The project will benefit the environment by removing toxic compounds from polluted wastewaters as well as potentially generating substantial levels of H2 (an attractive energy source). Project outcomes include the development of an economical and cleaner process for treating waters contaminated with heavy metals and providing a valuable knowledge base from which photoreductive efficiencies can be drawn.Read moreRead less
A scalable and portable question-answering system. The current availability of large volumes of free text digitally stored demands the development of methodologies that can automatically find specific answers to user questions about this "unstructured" information. The goal of this project is to develop a scalable portable and domain-independent real-time natural-language question-answering system that explores the logical contents of the text.

The current availability of large volumes of free text digitally stored demands the development of methodologies that can automatically find specific answers to user questions about this "unstructured" information. The goal of this project is to develop a scalable portable and domain-independent real-time natural-language question-answering system that explores the logical contents of the text. To achieve this we will fuse current approaches to question answering with approaches that look at the logical contents of the questions and answer candidates. A central part of the project will be the characterisation of the optimal logical forms, the determination of efficient methods to create and store sentence logical forms of potentially large volumes of text, and the treatment of difficult questions by incorporating summarisation and text generation techniques.Read moreRead less
A Layered Controlled Natural Language for Knowledge Representation. In this research project we will develop a controlled natural language for knowledge representation that has the potential to bridge the gap between fragments of natural language and formal languages. This controlled language will be based on a variety of increasing sophisticated layers, each building upon those below it by providing enhancements in expressive power. Sentences of the controlled language will be unambiguously tra ....A Layered Controlled Natural Language for Knowledge Representation. In this research project we will develop a controlled natural language for knowledge representation that has the potential to bridge the gap between fragments of natural language and formal languages. This controlled language will be based on a variety of increasing sophisticated layers, each building upon those below it by providing enhancements in expressive power. Sentences of the controlled language will be unambiguously translatable into a corresponding formal language. Anyone who can read and write English can immediately use the controlled language with the help an intelligent text editor. This technology will make it possible for non-specialists to write problem specifications in terms of the application domain without the need to formally encode the information.Read moreRead less
A Skin Detection Micro-Sensor for Face Identification using Color and Stereo Information. The objective of this research is to develop a micro-sensor for face identification, using color and stereo information. The micro-sensor chip performs a real-time search of the scene to locate human skin for subsequent face detection.

Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description ....Soft solids rheology and filled elastomeric networks.
