چکیده

Model based diagnostic systems have generally avoided the issue of multiple failure diagnosis due to the computational complexity of covering all possible multiple faults and still providing an efficient diagnostic strategy. Optimization of decision trees is already known to be NP-complete, and the number of combinations of multiple faults just serves to exacerbate the problem. Nevertheless, model based diagnosis is becoming popular, and the need for multiple failure diagnosis is real. In this paper, we will provide a formal analysis of the multiple failure problem in the context of one model based approach. Specifically, we will discuss algorithms and their complexity for diagnosing multiple failures using the information flow model.

A Rare Presentation of Multiple Myeloma: A Case Report of Hepatic Amyloidosis

The clinically reported case of liver involvement with multiple myeloma (MM) is rare. Amyloidosis, defined as a tissue deposition of clonal light-chain fibrils, has been reported in 10-15% of the MM patients. We described a rare MM patient with the primal presentation of fulminant hepatic failure and biliary system involvement due to amyloidosis. Our patient had the primal symptoms of hyperbili...
