The study of wear debris using advanced technologies. A large portion of the operating cost of machinery is associated with wear due to the interaction between moving surfaces, which generates wear particles as by-products. The wear particles thus carry information regarding the wearing process, and can be used to assess the machine's condition and further facilitate failure prediction and minimise maintenance. This project will explore the mechanisms and possible influence of corrosion on the w ....The study of wear debris using advanced technologies.

Vibration and wear debris analyses are the two main condition monitoring techniques for machinery maintenance and fault diagnosis. However, they can diagnose less than 50% of faults. A series of experimental and theoretical studies on the correlation of the two techniques will be conducted. This project will integrate advanced technologies including 3D microscopy, neural networks and expert systems to develop an artificial intelligent system based on the dependent and independent roles of the two condition monitoring techniques. Successful outcomes will result in an improved maintenance program and reduction in human involvement, and will provide significant economic benefit to engineering industries.Read moreRead less
Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and ....Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and an increase of interference. The aim of this project is to demonstrate an alternative method of maintaining good quality communication link. The proposed method employs a smart antenna system to mitigate adverse effects of multi-path and interference.Read moreRead less

Gears are widely used in industry and transport. This project aims to integrate the two main methods of gear condition monitoring, vibration and oil analysis, and perform model-based wear prediction with the tribology and dynamic models continually updated on the basis of measured wear debris and vibration. New signal processing tools should allow estimation of relatively weak friction forces, previously neglected, as an important prognostic tool. This would allow detailed root cause analysis and prediction of remaining useful life. Improvements in gear prognosis would have safety and economic benefits by eliminating unforeseen catastrophic failures and optimising maintenance schedules.Read moreRead less
