    Historically, whenever a unique digital interface was needed, a unique piece of hardware was created. In the field of loaders/verifiers this has often led to large, heavy, and expensive equipment to support aircraft platforms. Field programmable gate arrays (FPGAs) can be used to create many different interfaces without the need for unique hardware. This paper explores the techniques used to devel... View full abstract»

    Accounting for the effects of test uncertainty is a significant problem in test and diagnosis. Specifically, assessment of the level of uncertainty and subsequent utilization of that assessment to improve diagnostics must be addressed. One approach, based on measurement science, is to treat the probability of a false indication (false alarm or missed detection) as the measure of uncertainty. Given... View full abstract»
