Abstract:

Effort is presented to prove the feasibility of providing field instrumentation capable of measuring the rate of degradation of performance in individual electronic devices. The major effort was expended in the following areas to 1 develop a fresh approach to the prediction problem in order to develop a valid statistical class transition matrix V 2 develop the programming procedure for periodically updating the embryonic transition matrix V 3 study the possible ways in which eigenvalue solutions can be utilized in determining the entries in the unit modifier matrix V and 4 make repetitive measurements on all the ANPRC-6 radio sets at 20-hour operating intervals, under reduced voltage stress conditions, in order to determine whether greater accuracy can be obtained from the parametric measurements, and thus a more highly developed class transition matrix V and a more accurate prediction vector P.
