Subject: Integrity Analysis vs. Reliability
I am looking for information on an analysis technique for mechanical components that uses the design calculations as part of the Reliability analysis. I have heard that there is a method called "Integrity Analysis" that meets this criteria, but I have been unable to find any further information. Any information on this techique would be most appreciated.

Hi to All: What is there in the technical literature on failure rate models and/or failure mode/mechanism distributions for MEMS (microelectromechanical systems) devices?

Subject: Reliability Surveillance Testing
Often systems are "stockpiled" awaiting use in an operational environment (e.g., missiles or chemical suits stored until wartime), and there is a need to regularly (e.g., yearly) inspect the stockpile to check for possible reliability degradation. I am interested in methodologies for determining (1) how many articles to test at each prespecified time point, and (2) how to combine testing results to estimate current and future system capabilities. I am particularly interested in methodolgies that account for trends in the data, e.g., recent testing failures might reasonably be expected to signal additional testing requirements. Thanks in advance for your consideration. Arthur Fries

I am working in the area of FMECA on power supplies. I am yet to see a live example of detailed component level FMECA on power supply with compensating provision/corrective action. Can anybody give me a case study on the same. A detailed case study on any electronic circuit also will be of help to me. Thanks sumandra
