Journal Article
Muneer, T. & Munawwar, S. (2006)
Improved accuracy models for hourly diffuse solar radiation. Journal of Solar Energy Engineering. 128, 104-117. doi:10.1115/1.2148972. ISSN 0199-6231
Solar energy applications require readily available, site-oriented, and long-term solar data. However, the frequent unavailability of diffuse irradiation, in contrast to its n...

Investigating the Use of Audio Feedback in Engineering Mathematics Modules. ISBN 978-1-873769-14-0
Assessment and feedback are an important part of student learning, and there is evidence that good feedback leads to improvements in both learning and student engagement. This...

Wavelet transform reassignment and the use of low-oscillation complex wavelets.

Journal Article
Addison, P., Morvidone, M., Watson, J. N. & Clifton, D. (2006)
Wavelet transform reassignment and the use of low-oscillation complex wavelets. Mechanical Systems and Signal Processing. 20, 1429-1443. doi:10.1016/j.ymssp.2005.03.002. ISSN 0888-3270
In this paper, we explore the use of new time-frequency reassignment tools for the enhancement of prominent features in the time-frequency plane of the wavelet transform. The ...
