120 Mbps Mobile WiMAX Scalable OFDMA Signal Transmission over RoF with SMF, DCF and Chirped FBG for Fibre Length of 792 km
Found in: Wireless and Mobile Communications, International Conference on
By Mazin Al-Noor, Kok-Keong Jonathan Loo, Richard Comley
Issue Date:September 2010
pp. 373-377
Fibre attenuation and chromatic dispersion are the most important problems that create slops, changes of the frequency spectrum. Therefore the signal can only be clearly transmitted over a limited distance. In order to increase the signal transmission dist...
 
Toward a Robust System to Monitor Head Motions during PET Based on Facial Landmark Detection: A New Approach
Found in: Computer-Based Medical Systems, IEEE Symposium on
By Sergey Anishchenko, Vladislav Osinov, Dmitry Shaposhnikov, Lubov Podlachikova, Richard Comley, Xiaohong W. Gao
Issue Date:June 2008
pp. 50-52
A new approach for the detection of head motions during PET scanning is presented. The proposed system includes 4 modules, which are: input module, face segmentation, facial landmark detection, and head movement estimation. The developed system is tested o...
 
A Hybrid Wavelet-Based Compression System
Found in: Information Technology and Applications, International Conference on
By Vooi Voon Yap, Richard Comley
Issue Date:July 2005
pp. 780-783
The recent trend in picture messaging via mobile devices is producing a new demand for highly effective colour image compression. Current techniques favour wavelet filters that process the image as a whole. While this offers many advantages, it can lead to...
