A fixed-parameter tractability result for multicommodity demand flow in trees
We study an NP-hard (and MaxSNP-hard) problem in trees--Multicommodity Demand Flow--dealing with demand flows between pairs of nodes and trying to maximize the value of the routed...

Global complete observability and output-to-state stability imply the existence of a globally convergent observer
In this paper we consider systems which are globally completly observable and output-to-state stable. The former property guarantees the existence of coordinates such that the dyna...
