In the United States of America, numerous organizations are writing standards and recommend practices for contamination control and cleanroom applications. The American Society for Testing and Materials (ASTM), the Institute of Environmental Sciences (IES), and various US Government agencies are...

On May 19, 1992, the Secretary of Energy signed the revised DOE Order 1300.2A, Department of Energy Technical Standards Program, which set the policy and assigned responsibility for activities within the program. The purpose of the revision to the order was to place greater emphasis on the use...

In this paper a methodology for analytically estimating the response of replacement components in a system subjected to worst-case hostile shocks is presented. This methodology does not require the use of system testing but uses previously compiled shock data and inverse dynamic analysis to...

Today's typical multi-criteria decision analysis is based on classical expected utility theory that assumes a mythical ''Rational Individual'' immune to psychological influences such as anticipated regret. It is therefore in conflict with rational individuals who trade-off some benefits and...

Lawrence Livermore National Laboratory (LLNL) is working with the Department of Homeland Security's Science and Technology Directorate, the Transportation Security Administration, and several infrastructure partners to characterize and help mitigate principal structural vulnerabilities to...

Structural system identification methods are analytical techniques for reconciling test data with analytical models. The response data frequently used to compare a finite element model and test data are the eigenvalues of the system. However, eigenvalues alone cannot assure an adequate model....

In this paper, an overview of our findings concerning the distribution of activity within low-level radioactive wastes will be presented. This will begin in a general fashion and consider the distribution of the total activity by each of the following: waste class, waste stream, wasteform, and...

The International Institute of Welding is composed of some 600 technical experts from 36 countries. These individuals are divided by talent and personal interest into fifteen separate groups called Commissions, each with its own charter and goals. The title, and by inference the charter, of...
