This paper gives a practical systematic approach towards the maintenance procedure optimisation of critical industrial unit in operation, to improve its maintainability. The resolution maintainability challenge (Vibrating screen - VSU) was realised by performing two-phase analysis, encompassing criticality and assessment. assessment comprised failure investigation using fault tree analysis (FTA...

This paper combines relevant research in software reliability engineering and software measurement to develop an integrated approach for the early measurement and improvement of software quality. Recent research in these areas is extended 1) to select appropriate software measures based on a formal model, 2) to construct tree-based reliability models for early problem identi cation and quality ...

The Satellite Navigation and Positioning Group (SNAP) at the University of New South Wales and the DSO National Laboratories, Singapore, have jointly collaborated in the development of an integrated GPS, INS and pseudolite system for aircraft precision approach and landing. Flight tests were carried out in April/May 2003 to study the overall performance, and associated limitations, of such an i...

Neural networks, particularly the multilayer perceptron, have been used extensively in automated signal classification systems with classification accuracy as the figure of merit. Three important issues that can enhance the utility of these systems are (i) incremental learning, (ii) confidence or reliability measures and (iii) performance improvement through continual learning. This paper inves...

BACKGROUND Modic changes (MC) have been linked with low back pain (LBP) and worse outcomes from some treatments. No studies have investigated the impact that MCs may have on patient outcomes from lumbar facet injections. Therefore, the purpose of this study is to investigate whether the presence of Modic changes is related to 'improvement' in patients undergoing imaging-guided lumbar facet inje...

Software reliability is closely influenced by the creation, manifestation and impact of software faults. Consequently, software reliability can be improved by treating software faults properly, using techniques of fault tolerance, fault removal, and fault prediction. Fault tolerance techniques achieve the design for reliability, fault removal techniques achieve the testing for reliability, and ...

Growing concern about patient safety and healthcare quality has led some to borrow principles of reliability from industries with exceptional records of safety and reliability. Enhancing the quality of clinical decisions is fundamental to quality improvement. This paper argues that commitment to reliability enables the effective deployment of informatics tools that are, in turn, essential for e...
