System BV is NP-complete
System BV is an extension of multiplicative linear logic (MLL) with the rules mix, nullary mix, and a self-dual, non-commutative logical operator, called seq. While the rules mix ...

On Exponential-Time Completeness of the Circularity Problem for Attribute Grammars
Attribute grammars (AGs) are a formal technique for defining semantics of programming languages. Existing complexity proofs on the circularity problem of AGs are based on automata...

A Dynamic JKR Model with Application to Vibrational Release in Micromanipulation
— In this paper a dynamic contact model is presented based on the Johnson-Kendall-Roberts (JKR) theory. The classical JKR model captures the contact properties for the quasi-stat...
