This paper addresses intricate diagnosis situations in modern cars. It employs a rather new and little known diagnosis paradigm, which is a mixture of model-based and heuristic diagnosis and which is called model compilation [5, 25, 26]. The basic idea is to simulate a model of the system under study in various fault modes and over its typical input range(More)
Chinese hamster ovary (CHO) cells strain D422, which has one copy of the adenine phosphoribosyl transferase (APRT) gene, were permeabilized by electroporation and treated with 5-methyl deoxycytidine triphosphate. Cells with a silenced APRT gene were selected on 2, 6-diaminopurine. Colonies were isolated and shown to be reactivated to APRT+ by 5-aza-cytidine(More)
Though various sophisticated concepts for the diagnosis of technical systems have been developed, diagnosis technology in practical applications often boils down to the use of simple heuristics, associative case memories, or manually designed decision trees. These approaches are robust, but restricted with respect to the complexity of the diagnosed system(More)
