One of the most significant unsolved problems for network managers and system administrators is how to repair a network infrastructure after discovering evidence of an extensive compromise. The technical issues are compounded by a breathtaking variety of human factors. We present a study of three significant compromises of a medium-scale network infrastructure. We do so as a way to expose the d...

Small asteroids are often considered to be rubble-pile objects, and such may the most likely type of Near Earth Objects (NEOs) pose a threat Earth. However, impact cratering on bodies is complex not yet understood. We perform three low-velocity (? 400 m/s) experiments in granular targets with without projectile-size boulders. conducted SPH simulations that closely reproduced experiments. Our re...

The sport of rock climbing has undergone a significant change in recent times with technically harder climbs being attempted more often. This has meant that climbers have taken to more training including weight training, using artificial climbing walls and the more traditional 'bouldering' i.e. training on natural outcrops and boulders. This increase in standards has led to injuries associated ...
