Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
Ultrasonic flaw sizing is critical in nondestructive evaluation. However, the data available for sizing are often quite limited. For example, it is common to have a single pulse-echo (back scattered) wavetrain of limited bandwidth: i.e. it contains wavelengths that are comparable to and larger than the dimensions of the flaw. On the other hand a fair amount is often known about the nature of the expected range of flaws. It may be known that the flaw is a void, or a crack or an inclusion of a certain material type. In addition the expected shape for a flaw may be known (e.g. the flaw may be known to be a spherical flaw of unknown radius). The problem is then to determine the relevant unknown features of the flaw from the available data.
