Ringing the Changes: Mapping Networks of Support for Two Doctoral Students

Supporting postgraduate students in their efforts to soar through the rings is a crucial endeavour of contemporary universities. A variation on this approach is ringing the changes for such students – that is, identifying the distinct stages in their learning journeys and seeking ways to maximise opportunities to facilitate their movement through each stage and in the transition from one stage ...

A Novel Smart Bilateral Filter for Ringing Artifacts Removal in JPEG2000 Images

Ringing artifacts arise near edges in highly compressed JPEG2000 images. This paper proposes original image ringing detection and suppression techniques. On the first stage edge detection and ringing estimation algorithms are applied to calculate the ringing map of a compressed input image. On the second stage this ringing map is utilized to adjust the smart bilateral filter for effectively pro...

Spatio-Temporal Fuzzy Filtering For Ringing Artifacts Reduction

A 3D fuzzy-filtering scheme is proposed for reduction of compression artifacts such as blocking and ringing noises. The proposed scheme incorporates information from temporally-neighboring frames as well as from spatiallyneighboring pixels by accounting for the spatio-temporal relationships in the definitions of spatial-rank orders and spread information for the fuzzy-filter. Extra information ...

Bells, Motels and Permutation Groups

This article is about the mathematics of ringing the changes. We describe the mathematics which arises from a real-world activity, that of ringing the changes on bells. We present Rankin’s solution of one of the famous old problems in the subject.
