Seeded faults
WebA “seeded fault test,” in support of a rotorcraft condition based maintenance program (CBM), is an experiment in which a component is tested with a known fault while health monitoring data is collected. These tests are performed at operating conditions comparable to operating conditions the component WebQ3. (10 points) (show your work) a) A program is seeded with 30 faults. During testing, 21 faults are detected, 15 of which are seeded faults and 6 of which are indigenous faults. What is the Mill's estimate of the number of indigenous faults remaining undetected in the program? b) You claim that your program is fault- free at a 95% confidence ...

Web413 Midexam. Term. 1 / 60. This approach assumes that the seeded faults are the same kind and complexity as actual faults in the program. But we do not know what the typical faults are before we have found them, so it is difficult to make the seeded faults representative of the actual ones. Click the card to flip 👆. Webhand-seeded faults, and a widely-used program with real faults. We generated mutants from the subject programs using a set of standard mutation operators from the literature on mutation testing. Our results suggest that the generated mutants were similar to the real faults but different from the hand-seeded faults, and that the hand-
