We introduce a new notion of bisimulation for showing contextual equivalence of expressions in an untyped lambda-calculus with an explicit store, and in which all expressed values...
Transient faults are single-shot hardware errors caused by high energy particles from space, manufacturing defects, overheating, and other sources. Such faults can be devastating f...
