The art of test is being able to anticipate and replicate the stresses of a product's intended end use. This paper is an overview of a range of test options for wireless transmitter-receiver pairs; in particular those that will ultimately experience separation distance, or relative motion, thereby introducing a wide range of additional Radio Frequency (RF) effects, not typically found in indoor wireless...
For Aircraft Launch and Recovery Equipment (ALRE), the goal is to get planes in the air and ensure they land safely. Consequently, a high operational availability (Ao) is crucial to ALRE operations. In order to ensure high Ao, it is crucial that the amount of maintenance, both corrective and preventative, is kept to a minimum. Historically, improvements have been reactive in nature to satisfy the...
Testability modeling has been performed for many years. Unfortunately, the modeling of a design for testability is often performed after the design is complete. This limits the functional use of the testability model to determining what level of test coverage is available in the design. This information may be useful to help assess whether a product meets a requirement to achieve a desired level of...
Prognosis is a fundamental enabling technique for condition-based maintenance (CBM) systems and prognostics and health management (PHM) systems and therefore, plays a critical role in the successful deployment of these systems. The purpose of prognosis is to predict the remaining useful life of a system/subsystem or a component when a fault is detected. Although different prognostic algorithms have...
