The following questions are often encountered in system and control theory. Given an algebraic model of a physical process, which variables can be, in theory, deduced from the inp...
We explore the power of relational semantics and equational reasoning in the style of Kleene algebra for analyzing programs with mutable, statically scoped local variables. We prov...
Firewalls are a cornerstone of todays security infrastructure for networks. Their configuration, implementing a firewall policy, is inherently complex, hard to understand, and diff...
This paper presents a new test response compaction technique with any number of unknown logic values (X’s) in the test response bits. The technique leverages an X-tolerant respo...
