The system described by Barker et al 2011 has been used in a number of applications, a few of which have been published (see below). Shaun Barker and Andreas Beinlich have been working with LGR on a second generation system with a number of improvements, including smaller sample sizes (although in our applications larger sample sizes are generally preferred). I expect that they will be able to make more on that system available in the new year.
