    For pt.VIII see ibid., vol.7, no.5, p.9 et seq. (1991). The physical aspects of partial discharge (PD) in SF/sub 6/ gas-insulated substations (GIS) are reviewed. The orientation is toward present and developing techniques for evaluating defects in solid and gaseous insulation systems on the basis of PD measurement. Standard evaluation methods provide an indication of PD in GIS, but cannot quantita... View full abstract»

    Guidelines are presented for assessing the reliability of commercial-grade motors over a period of time when used in mild environments, where, among other effects, total radiation dose would be of the level of 10/sup 4/ rads or less. These guidelines are based on using available data on life tests, failure programs and modes, and selected analytical techniques. The goal is to determine that motors... View full abstract»

    The nature of the polymer-metal interface and its significance in microcircuitry are examined. The question of ohmic contact is considered. The example of polymer metallization demonstrates that peripheral issues can often be of critical importance to the functioning of a device.<> View full abstract»
