Predicting channel incision of low relief landforms

Water movement processes through the landscape to the stream requires an understanding of run-off, lateral flows and groundwater processes. The conceptualisation of how these processes interact in the landscape plays a vital role in the development of water and solute movement models. The development of such models are used to inform management decisions. These decision are becoming more focuse...

Dead letter or living document? Ten years of the Code of Conduct for disaster relief.

This paper examines the present value of the Code of Conduct for the International Red Cross and Red Crescent Movement and Non-Governmental Organizations (NGOs) in Disaster Relief, in view of discussions on neutrality and the Western bias of the humanitarian aid system, and assesses how it can retain its relevance in future. The Code of Conduct was launched just after the Rwanda genocide of Apr...

Low complexity guaranteed fit compound document compression

We propose a new, very low complexity, single-pass, algorithm for compression of continuous tone compound documents, known as GRAFIT (GuaRAnteed FIT) that can guarantee a minimum compression ratio of as much as 12:1 and even more, for all images in a single pass, while maintaining visually lossless quality when reproduced at resolution 300 dpi or more. The compression ratio is guaranteed in a s...

Motion of specularities on low-relief surfaces: frequency domain analysis

Typical studies of the visual motion of specularities have been concerned with how to discriminate the motion of specularities from the motion of surface markings, and how to estimate the underlying surface shape. Here we take a different approach and ask whether a field of specularities gives rise to motion parallax that is similar to that of the underlying surface. The idea is that the causti...
