On the Energy Efficiency of LT Codes in Proactive Wireless Sensor Networks
This paper presents the first analysis on the energy efficiency of LT codes with Non-Coherent M-ary Frequency Shift Keying (NCMFSK), known as green modulation [1], in a proactive W...

Grey Scale Image Skeletonisation from Noise-Damped Vector Potential
This paper describes a method for curvature dependant Skeletonisation in grey-scale images. We commence from a magnetostatic analogy, where the tangential edge flow (the cross pro...

Database-friendly random projections
A classic result of Johnson and Lindenstrauss asserts that any set of n points in d-dimensional Euclidean space can be embedded into k-dimensional Euclidean space -- where k is lo...
