It is a well known problem that the attack recovery of a self-healing system rolls back not only malicious transactions, but also legitimate transactions that are dependent on the...
The parallel branching program machine (PBM128) consists of 128 branching program machines (BMs) and a programmable interconnection. To represent logic functions on BMs, we use qua...
In the clock semantics for epistemic logic, two situations are indistinguishable for an agent when it makes the same observation and the time in the situations is the same. The pa...
Abstract. I develop a compositional theory of refinement for the branching time framework based on stuttering simulation and prove that if one system refines another, then a refine...
