chromate conversion coating is applied on aluminum 6061. the optimum conditions for chromate bath composition and immersion time are also obtained for standard requirements provision such as corrosion resistance in salt spray test, electrical resistance and coating quality. the applied coatings are electrochemically tested in sea and distilled water. according to tafel and cyclic polarization c...

Fault prediction is the precondition of Condition Based Maintenance (CBM), accurate prediction for equipment can not only make warning before failure occurs, but also reduce the cost of maintenance of complicated equipment and system. Therefore, it is of profound importance to make research on fault prediction of electronic equipment. This paper analyses some typical fault prediction method of ...

We hypothesized that our institutional standard practice for preanesthesia equipment checkout, based in part on US Food and Drug Administration recommendations, failed to detect a significant number of faults (absent or nonfunctional equipment). We designed a new, computer-based, highly interactive electronic checklist that emulated the checklist methods used in aviation and military settings a...

The authors have been involved in the implementation of a total quality control project in a communications equipment company, whose products are mounted and tested in a manufacturing plant controlled by an IBM Token Ring LAN. The first implementation of total quality control project was an ATE (Automatic Test Equipment) LAN node that runs a program of verification for single-channel and multic...
