This paper uses a Markov process to model a real-time expert system architecture characterized by message passing and event-driven scheduling. The model is applied to the performance evaluation of rule grouping for real-time expert systems running on this architecture. An optimizing algorithm based on Kernighan-Lin (KL) heuristic graph partitioning for the(More)
Heparin cofactor, a thrombin inhibitor, is purified from human plasma by affinity chromatography on heparin-agarose. The nature of the binding between thrombin and the inhibitor is studied by treatment of the complex with 6 M guanidinium chloride, hydroxylamine, and dilute alkali. The complex is not dissociated during gel chromatography in 6 M guanidinium(More)
