This paper presents a fuzzy knowledge-based system for turbomachinery diagnosis. Given symptoms associated with a vibration problem, the system can identify and rank possible causes by performing incremental forward chaining. The diagnostic system incorporates an attribute weighting component to reflect the relative significance of conditional attributes, thereby allowing the system to produce ...

This paper presents an integrated knowledge-based system, which combines fuzzy rule-based reasoning with case-based reasoning, for turbomachinery diagnosis. By incorporating a casebased reasoning sub-system in a fuzzy rule-based system, the integrated system allows past experience to be applied in a more direct way. This helps improve the diagnostic accuracy of the rulebased system. This approa...

P roblems requiring inferencing with Boolean logic have been implemented in percept rons or feedforward networks, and some attempts have been made to implement fuzzy logic based inferencing in similar networks. In this pap er, we present producti ve networks , which are art ificial neur al networks, meant for fuzzy logic based inferencing. The nod es in t hese networks collect an offset product...

japan, known as a pro-choice country in terms of abortion, is currently facing the increase of “selective abortions” thanks to new prenatal screening. efforts to restrict proliferation of new technology has not been successful and it is likely that japan will turn pro-life by strictly enforcing the maternity protection act (mpa), which prohibits abortions due to “fetal cause”.
