The International Standards System and NDE

December 1, 1999
Author(s)
Thomas A. Siewert
The globalization of manufacturing and construction markets is broadening the range of inspection standards that might be specified for a product, and we should prepare by learning more about the various organizations that develop such standards. The paper

The Theory of Bose-Einstein Condensation of Dilute Gases

December 1, 1999
Author(s)
Karen G. Burnett, M Edwards, Charles W. Clark
In this article, we present a current perspective on advances in the theoretical understanding of Bose-Einstein condensation from the standpoint of atomic, molecular and optical (AMO) physics. In AMO physics, BEC has come to be perceived both as an

Ultrasonic Nonlinearity Parameter in Precipitate-Hardened Steels

December 1, 1999
Author(s)
Donna C. Hurley, Davor Balzar, P T. Purtscher
We have experimentally investigated a series of steel specimens containing copper-rich precipitates. The precipitate microstructure depended on the final aging treatment (time and temperature), which in turn affected the specimen hardness. We performed
