Blind restoration of blurred photographs via AR modelling and MCMC
We propose a new image and blur prior model, based on nonstationary autoregressive (AR) models, and use these to blindly deconvolve blurred photographic images, using the Gibbs sa...

Performance Modelling of Peer-to-Peer Routing
We propose several models based on discrete-time Markov chains for the analysis of Distributed Hash Tables (DHTs). Specifically, we examine the Pastry routing protocol, as well a...
