A user’s guide is presented for Standard Reference Material (SRM) 2569 Lead in Paint Films for Children’s Products. This SRM consists of paint films on coupons of polyester with the paint characterized for mass fraction of Pb, mass of Pb per unit area

Cross-sectional stability of structural steel at elevated temperatures

April 19, 2012
Author(s)
Therese P. McAllister, Mina S. Seif
There is a lack of understanding of how structural systems perform under realistic, uncontrolled fires. Current specifications for the design of steel structures in the US do not include fire effects as part of structural design. Instead, fire protection

Evaluation of Fusion Methods for Latent Fingerprint Matchers

March 29, 2012
Author(s)
Vladimir N. Dvornychenko
Matcher fusion is a recognized approach for improving biometric system performance. Our interest in fusion was largely to determine how much performance "headroom" exists with current matcher technology. We employed five latent fingerprint matchers, having
