Special Session 12

Instrumentation and measurement for improving quality, reliability and safety: new perspectives for research and industry

 

Description

Nowadays in many contexts it is mandatory to fulfill performance of Testing and Diagnostics, Reliability, Maintainability, Safety and Risk assessment. Such tasks play a fundamental role in different fields of application (energy, transportation, information and communication technology, logistics, etc.) and are considered as fundamental in high-tech industry and plants. This Special Session represents an interesting opportunity for engineers and researchers who work in this area to meet and discuss about live issues. In particular, useful and beneficial discussion can be promoted with the aim to provide an increasing of knowledge and an easier diffusion of the most recent developments. Prospective authors can provide original contributions in this topic which can cover, but not only, the following aspects:

  • Instrumentation and measurement methods for Testing and Diagnostics (Destructive and Non-destructive Testing, Vibration monitoring, Built-in Test Equipment and Automatic Test Equipment, etc.)
  • Condition monitoring and maintenance of industrial process, plants and complex systems
  • Measurements and techniques for Fault detection and diagnosis
  • Design and implementation of laboratory tests (Reliability test, Environmental test, Burn-in test, Vibration test, etc.) and Qualification tests for components, assemblies and process
  • Measurements, methods and instrumentation for evaluation of Reliability, Availability, Maintainability and Safety (RAMS), Risk assessment and management
  • Impact of RAMS requirements in the emerging technologies for Life and Society, environment and new energy sources
  • Effects of measurement uncertainty on the estimation of the RAMS parameters
  • Standards definition, certification and accreditation.

Application of Moment-based Measurement Uncertainty Evaluation to Reliability Analysis of Structural Systems

 

Abstract

System and measurement uncertainties play a key role in finding the reliability of complex and safety-critical structural systems such as buildings and bridges. Current mainstream techniques in structural reliability analysis use an iterative first-order reliability method which performs an indirect uncertainty evaluation by finding the most probable failure point. However, such an approach could lead to high computational time due to slower convergence and in some cases, poor convergence that leads to unreliable results. In order to address these shortcomings, this paper applies a new high-order moment propagation technique, that was initially developed for measurement uncertainty analysis, to structural reliability analysis problems in an effort to obtain results that are simultaneously accurate and computational efficient. The proposed approach was implemented on a three-story elastic frame structure and the presented results prove that the application of a technique from the field of measurement uncertainly can indeed be applied to complex problems in structural reliability analysis in order to reduce the trade-off between accuracy and computational efficiency.

Bio

Melanie Ooi is an emerging researcher and engineering specialist in Electrical and Electronic Engineering as well as Computer Engineering and Computational Intelligence. She is currently an Associate Professor and Head of Engineering at Unitec Institute of Technology, New Zealand. While working in close collaboration with several leading multinational electronics companies, she has developed new testing techniques and test data processing methodologies that have been adopted by the industry partners. In the recent years she has also successfully researched on new measurement uncertainty evaluation approaches and frameworks with application to a multitude of science and technology areas (medical research, structural design, mechanical systems modelling, etc.). Her research competence and capability are evident from the extensive and fast growing list of publications, research grants and projects, as well as successfully supervised postgraduate students.

In addition, Associate Professor Ooi was particularly successful in the area of undergraduate and postgraduate education. She introduced several innovations and a well-structured education program enhancing key professional skills and thus increasing work-readiness and employability of engineering graduates that were successfully adopted and implemented by Monash University and RMIT University in their Southeast Asian campuses. They have been strongly supported by multinational electronics companies such as Intel, Freescale Semiconductor and National Instruments.

Her high professional achievements have been acknowledged by several prestigious awards including the Outstanding Young Engineer Award of the Year 2014 from the IEEE Instrumentation and Measurement Society, 2014 Excellence Award from the International Education Association of Australia, 2011 Citation for Outstanding Contributions to Student Learning from the Australian Learning and Teaching Council to mention a few. 

She is Senior Member of the IEEE, Member of the IEEE Instrumentation & Measurement Society (I&MS), Distinguished Lecturer and Secretary of the Technical Committee on Fault Tolerant Measurement Systems (TC-32) of the IEEE I&MS. She is also Member of the Institution of Engineering and Technology, and UK Chartered Engineer.
