Streaming video media using semantic information. Delivering video over the Internet has posted a big problem. Video files are extremely big and need hours or even tens of hours to download. This is too long to wait for the content. Much research has been attempted over low-level structures such as coding, buffer, protocol, agent and server. These techniques are either not scalable or impractical.

Delivering video over the Internet has posted a big problem. Video files are extremely big and need hours or even tens of hours to download. This is too long to wait for the content. Much research has been attempted over low-level structures such as coding, buffer, protocol, agent and server. These techniques are either not scalable or impractical. This project aims to collaborate with CyberView on developing a high-level scheme of streaming video using semantic information. It breaks videos into shots and allows semantic browsing of the content. It also introduces intelligent agents with various behaviours.Read moreRead less
Supporting adaptive diagrammatic communication. The computing environment of the near future will allow users to access and
interact with digital information using an incredible variety of devices.
Regardless of these changes, humans will still be communicating using
diagrams and sketches. But unlike today where diagrams are static,
lifeless objects reflecting their origin in print media, the computer of
the near future will provide more flexible visual computer interfaces which

Regardless of these changes, humans will still be communicating using
diagrams and sketches. But unlike today where diagrams are static,
lifeless objects reflecting their origin in print media, the computer of
the near future will provide more flexible visual computer interfaces which
support adaptive layout, user interaction and semantics based retrieval.
Based on geometric constraint solving, this project will provide a
generic computational basis for this radically new view of diagrams.

Scalable Visual Analytics for Uncertain Dynamic Networks. Technological advances have provided a data deluge over the past few years, and have led to many large uncertain and dynamic network models. This includes terrorist networks, marketing networks, facebook networks, various biological networks, and software engineering structures. Human understanding of such networks is difficult. This project aims to provide new methods for visual analysis of large uncertain dynamic networks such as these. ....Scalable Visual Analytics for Uncertain Dynamic Networks.

This includes terrorist networks, marketing networks, facebook networks, various biological networks, and software engineering structures. Human understanding of such networks is difficult. This project aims to provide new methods for visual analysis of large uncertain dynamic networks such as these. The algorithms developed in the project will help security analysts to monitor illegal behaviour such as money laundering and terrorist activities, help biologists understand key biological systems, and help engineers to understand large software systems.Read moreRead less
Human interaction with context-aware computing systems. Context-aware systems can provide seamless support of IT applications in a variety of technologies and therefore can improve: (i) work performance and adoption of IT in many industries; and (ii) the quality of life through better support for health services, education, and everyday tasks. Currently proposed solutions for context-aware systems fail to deliver systems which are usable for non-IT professionals. The proposed project will show h ....Human interaction with context-aware computing systems. Context-aware systems can provide seamless support of IT applications in a variety of technologies and therefore can improve: (i) work performance and adoption of IT in many industries; and (ii) the quality of life through better support for health services, education, and everyday tasks. Currently proposed solutions for context-aware systems fail to deliver systems which are usable for non-IT professionals. The proposed project will show how to design context-aware systems that are usable and whose autonomic decisions can be trusted. Additional benefits include increased scientific competitiveness of Australia, strengthened collaboration with international research institutions, and high quality graduates (PhDs, Masters, Honours).Read moreRead less
Minimising the inappropriate and unnecessary hospital admissions of frail older people. The health system will continue to experience massive pressures in both fiscal and human resource terms. Older patients present with multiple, complex conditions and tend to be admitted because clinicians often do not have the time to explore other options. This project will develop and evaluate a unique and robust model for minimising inappropriate hospital admissions through rapid assessment of suitability ....Minimising the inappropriate and unnecessary hospital admissions of frail older people. The health system will continue to experience massive pressures in both fiscal and human resource terms. Older patients present with multiple, complex conditions and tend to be admitted because clinicians often do not have the time to explore other options. This project will develop and evaluate a unique and robust model for minimising inappropriate hospital admissions through rapid assessment of suitability for home care and complete referral information for safety and quality.

An Empirically Derived Experimentally Validated Framework for Interactions in Information Environments. This project will investigate and design ways of interacting with the information infrastructure that maintain natural social interactions, take advantage of physical space and utilise our extensive human abilities to recognise and manipulate physical objects.

This project will investigate and design ways of interacting with the information infrastructure that maintain natural social interactions, take advantage of physical space and utilise our extensive human abilities to recognise and manipulate physical objects.
Expected outcomes include:
? a theoretical framework that describes the range of possible interactions that mediate information between the physical and virtual worlds.
? a prototype instrumented information environment that demonstrates and validates naturalistic information transactions identified in the framework.
This research is highly innovative in its field. It will use an iterative cycle of video observation, interaction analysis, user-centred device design, deployment and evaluation.

Protecting Web Services from Distributed Denial of Service Attacks. Distributed denial-of-service (DDoS) attacks bring a tremendous threat to web services on the Internet. Large amount of web services were pulled down worldwide by the DDoS attacks, with huge losses in business. Effective approaches to defeat DDoS attacks are desperately demanded. Most existing DDoS defense systems aim to only protect the victim network and are not fully integrated.

Distributed denial-of-service (DDoS) attacks bring a tremendous threat to web services on the Internet. Large amount of web services were pulled down worldwide by the DDoS attacks, with huge losses in business. Effective approaches to defeat DDoS attacks are desperately demanded. Most existing DDoS defense systems aim to only protect the victim network and are not fully integrated. In this project we propose a novel defense system to protect web services from DDoS attacks. Our system is one of the first systems that have a mixture deployment in both victim end and attack source end, and integrated capabilities of intrusion surveillance, traffic control, and traceback, thus achieve better control results over other mechanisms.Read moreRead less

Multi-resolution spatial query processing. The cost of spatial query processing is directly related to spatial data complexity and accuracy. While spatial data is often stored in a database with the highest level of detail available, not all applications require the same level of detail.

The cost of spatial query processing is directly related to spatial data complexity and accuracy. While spatial data is often stored in a database with the highest level of detail available, not all applications require the same level of detail. Recognising the difficulties of multiple representations of spatial data, in this project we propose to use multi-resolution data structures as a new foundation for efficient, application-dependent, on-demand derivation of data at different resolution levels. The systematic approach adopted in this project has the potential to deliver performance improvement that previous algorithm-level-only research cannot match.Read moreRead less
