    In an earlier paper3 which appeared in this Transactions, the author showed in the appendixes two methods of estimating the shape and scale parameters of a Weibull distribution from a set of life testing data. They are: (I) the method of least squares for the transformed data, and (II) the method of maximum likelihood for ungrouped data. It was pointed out that since the method of least...

    Choice of an electronic component or electron device for a particular application is more likely than not to be based on a personal estimate of one or two obvious attributes, such as first cost, assumed reliability or simply availability. The author proposes a set of five basic criteria, with quantitative evaluation, to comprehend all attributes of any candidate device or component. These criteria... View full abstract»

    The traditional method of checking acceptability of a lot of tubes for a particular electrical characteristic has been to test a large sample and count the number of tubes beyond the minimum or maximum limits - inspection by attributes. This reduces the chances of accepting a lot with a high percentage of defectives, but gives no assurance that the lot is centered close enough to bogey or that the... View full abstract»

    Reliability, so important to the future of commercial and military electronics, is at last becoming quantitative. Because the scope and problems are so great, it has taken much time to arrive at definite courses of action. Now reliability is emerging from generalities and desires to a concrete stage of evaluation, implementation and measurement. Reliability (a great concern to the electronics indu...

    Prior to the mid Forties most electron tubes were production-and quality-tested on an attributes (go-no-go) basis only. Quality-sample sizes were moderate and statistical paper work was at a minimum. Since that time quality-control testing has increased by leaps and bounds under the pressure for high reliability, performance, and uniformity. These factors have increased the quality-control work lo... View full abstract»

    Cathode interface impedance has usually been treated as if it could be represented at any given time by a parallel R-C combination. In actuality, however, the impedance can be represented accurately only by an R-C network containing four elements. Moreover, the interface undergoes a reversible change of state with a relaxation time near one second as the cathode current is changed. These character... View full abstract»

    This paper describes the use of a sampling method of inspection testing for the purpose of controlling reliability in a system. The acceptable quality level (AQL) and mean failure free time can be estimated by the maximum likelihood method, assuming that errors are distributed by the Poisson Law. Hence, a choice of quality levels or reliability levels can be made. Single or multiple sampling plans... View full abstract»

    In recent papers,1,2 optimal diagnostic procedures are presented for some special cases. In this paper, we present an optimal diagnostic procedure under a different restriction, i.e., we consider equipment in which elements can only be tested one at a time, or all at once. Optimality is in the sense of minimum expected cost. View full abstract»
