Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

This paper describes the development programme for a portable non-contact inspection system, suitable for in-service inspection of aeronautical structures. The instrument is powered from a re-chargeable battery pack which provides over six hours of continuous usage. The transducer front end is a lightweight, hand-held assembly in which a pair of piezocomposite transducers are housed. Angular adjustment of the transducers enables the instrument to operate into a variety of materials, with metallic and composite materials of primary interest. Importantly, a single channel oscilloscope has, been incorporated to provide visual interpretation of the processed received signal. Defect detection is demonstrated in a number of aerospace samples, with the resultant C-scans presented where appropriate.
