A Non-blocking Recovery Algorithm for Causal Message Logging (2009)
J. Roger, Mitchell Vijay, K. Garg
In the recovery of failed processes in a distributed program, causal logging schemes offer several benefits. These benefits include no rollback of unfailed processes and simple approaches to output...

Previous work in efficient detection of global predi-cates was restricted to predicates that could be specified as a boolean formula of local predicates. Many prop-erties in distributed systems,...
In 1856, one (or two) destructive earthquake(s) occurred off Djijelli (Algeria) and probably triggered a tsunami in the western Mediterranean Sea. Following recently published results of marine...

Linear Zonal Atmospheric Prediction for Adaptive Optics (2007)
Patrick Mcguire Troy, Patrick C. Mcguire, Troy A. Rhoadarmer, Hanna Coy, J. Roger, P. Angel
We compare linear zonal predictors of atmospheric turbulence for adaptive optics. Zonal prediction has the possible advantage of being able to interpret and utilize wind-velocity information from the...
