Title: Meshless, numerical modelling for polymer processing
Investigator(s): N. Mai-Duy
Sponsor(s): Australian Research Council
Period: 2006 - 2008
Abstract: This project will develop a powerful new neural-network-based procedure for the numerical modelling of polymer processing. Radial basis function networks are designed for the solution of complex partial differential equations that govern polymeric fluid flows. In the simulation process, no mesh is involved and the data points are optimally located. This will significantly improve the way that polymer products are designed, bringing major cost-efficiencies and improvements in product quality.
Title: Development of constitutive models for concentrated suspensions via particle-level simulations
Investigator(s): H. See (CI), N. Mai-Duy (CI) and P. Bacchin (PI)
Sponsor(s): Australian Research Council
Period: 2006 – 2008
Abstract: This project will develop a modelling framework to predict the microstructure of particle suspensions in flow, and will incorporate this information into continuum-level constitutive relations applicable in large-scale industrial problems. The complex macroscopic properties of suspensions are known to be due to mechanisms which are fundamentally microscopic in nature. Particulate aggregation and non-Newtonian viscosity are examples of complex macroscopic suspension properties arising from microstructure, which cannot be explained through continuum-level modelling. We will investigate the relationship between the microstructure and the macroscopic flow properties, using the theoretical framework and computational tools we will develop.

Title: Internet Pooling: Enabling Fast and Reliable Internet Access for Regional and Rural Communities
Investor(s): A.A. Kist
Sponsor: University of Southern Queensland,
Period: 2006/2007 Early Career Researcher Program.
Abstract: There is an increasing need for higher speed and more reliable internet access. This project proposes the investigation and development of a neighbourhood router system which will increase the usable capacity of shared high-speed and wireless broadband connections. It allows sharing of Internet resources between users and improves throughput and resilience to dropouts. Internet pooling can be used for both, telephone and network connections. The project aims are: to develop a software module that enables telecommunication resource sharing between several sites; to investigate mathematical models that analyse the performance of such a system; and to setup a testbed to prove the concept, and lastly evaluate the real life performance of an Internet pooling system.
Title: Cross Layer Performance Investigation of Wireless Broadband Channels in Indoor and Outdoor Areas
Investors: A.A. Kist, K.I. Ziri-Castro,
Sponsor: University of Southern Queensland, FOES Seed Funding.
Abstract: Wireless networks have become popular in recent years, however many open issues still remain. This project addresses performance evaluation of current wireless networking technology from two angles. It will investigate signal parameters of the transmission channel and relate them to performance experienced by an Internet or Internet-Telephony user. The second part will simultaneously examine indoor and outdoor connections, investigating the impact of weather conditions on in- and outdoor performance.

Investigator(s): T. Tran-Cong, W. Yan, G. Baker and A.J. Russell
Sponsor(s): ARC (Linkage Project)
Abstract: The aim of this project is to quantify the influence of the key factors involved in a fast hydraulic rock breaking technology through thorough theoretical modelling of the physical processes and the corresponding numerical solution.
Title: Numerical Modelling of Strain Localization in Reinforced Concrete and Its Application to Prediction of Crack Spacing and Crack Width
Investigator(s): G. Baker, T. Tran-Cong
Sponsor(s): ARC (Discovery Project)
Abstract: Cracking of concrete has a major influence on structural performance. Prediction of crack spacing and crack widths is essential for serviceability considerations of reinforced concrete. The available formulas to evaluate crack widths are approximate and give a wide scatter of predicted values. This project aims to provide a new numerical methodology that will (finally) predict crack spacing correctly. The expected outcomes include a numerical analysis model and a set of algorithms to predict crack widths. This will markedly improve the understanding of the mechanism of crack spacing and provide a better prediction of crack spacing and crack widths
Title: Controlled Vacuum Infusion: computational modelling and simulation for the manufacturing of fibre reinforced polymer (FRP) structures
Investigator(s): T. Tran-Cong, A. Khennane
Sponsor(s): QCIF and Buchanan Advanced Composites Pty Ltd
Abstract: The objective of the first stage of our collaborative strategy is to demonstrate the value of computational tools, particularly the Controlled Vacuum Infusion (CVI) simulation software called RTM-Worx, in product development at BAC.

Title: Towards a methodology of developing real time interactive multimedia applications on the Internet of the future
Investigator(s): Dr Zhongwei Zhang, Dr Shanmugathasan Suthaharan
Period: 2003 -- 2008
Abstract: Emerging multimedia networking applications are sensitive to the Quality of Service rendered by the underlying network architecture. There is, however, no methodology to develop real-time interactive multimedia applications on the DiffServ network. Our objective is to develop a methodology of constructing multimedia applications on the DiffServ network. The hypothesis is that the DiffServ model is able to cater for differentiated services. The rationale is that the packets generated by multimedia networking applications can be categorised into forwarding classes, and the underlying network will then treat the forwarding classes differently using active queue management and weighted priority queuing techniques.
Title: Efficient Algorithms on Active Networks Assure Quality of Service of Multimedia Networking Applications
Investigator(s): Dr Zhongwei Zhang
Period: 2004 – 2008
Abstract: Multimedia networking applications requiring quality of service (QoS) have stretched the current computer networks to its limits. This project investigates a new approach to designing computer networks that overcome the current networks' problem of inability to provide a QoS guarantee to multimedia networking applications. The project will develop an architecture, including protocols and functions for the network nodes, which is particularly suitable for the processing of application specific data generated by multimedia networking applications. The project will also explore efficient algorithms for network nodes to carry out some operations in order to satisfy the end-to-end QoS requirements of multimedia networking.
