Devices of interconnected parallel acting sequential automata are investigated from a language theoretic point of view. Starting with the well-known result that each unary language...
This paper compares Propositional Dynamic Logic of Non-Regular Programs and Fixpoint Logic with Chop. It identifies a fragment of the latter which is equiexpressive to the former....
We consider the problem of incrementally rendering a polyhedral scene while the viewpoint is moving. In practical situations the number of geometric primitives to be rendered can ...
