The Pentagon Building Performance Report

January 1, 2003
Author(s)
P E. Mlakar, D O. Dusenberry, J R. Harris, G A. Haynes, Long Phan, M A. Sozen
Following the September 11 crash at the Pentagon of an airliner commandeered by terorists, the American Society of Civil Engineering established a building performance study team to examine the damaged structure and make recommendations for the future. The

The Sandwich Bending Specimen for Characterizing Adhesive Properties

January 1, 2003
Author(s)
Donald L. Hunston, Z Z. Miyagi, Carl R. Schultesiz, S Zaghi, H Binson
Techniques to characterize the mechanical properties of adhesives in a bond geometry are important because the behavior can differ from that of bulk adhesive samples. Although there are a number of such tests, the simplicity of the sandwich beam specimen

The Structural Evolution of Pore Formation in Low-K Dielectric Thin Films

January 1, 2003
Author(s)
M S. Silverstein, Barry J. Bauer, V. J. Lee, R C. Hedden, B G. Landes, J L. Lyons, B Kern, J Niu, T Kalantar
Specular x-ray reflectivity and small angle neutron scattering were used to characterize changes in the porosity, pore size and pore size distribution on processing a SiLK oligomer filled with 21.6 %v/v of a deuterated porogen with an average radius of 56

The Time Dependence of Liquid Helium Fluorescence

D N. McKinsey, C R. Brome, S N. Dzhosyuk, R G. Golub, K Habicht, P R. Huffman, E Korobkina, Steve K. Lamoreaux, C E. Mattoni, Alan Keith Thompson, L Yang, John M. Doyle

The Validation of CMM Task Specific Measurement Uncertainty Software

January 1, 2003
Author(s)
Steven D. Phillips, Bruce R. Borchardt, A Abackerli, Craig M. Shakarji, Daniel S. Sawyer, P Murray, B Rasnick, K Summerhays, J M. Baldwin, M P. Henke
Task specific CMM measurement uncertainty statements can be generated using computer (Monte Carlo) simulation. Recently, commercial products using this powerful technique have become available; however they typically involve megabytes of code inaccessible

The Virtual Cement and Concrete Testing Laboratory Version 3.0

January 1, 2003
Author(s)
Jeffrey W. Bullard
This NISTIR serves as the user's manual for Version 3.0 of the Virtual Cement and Concrete Testing Laboratory (VCCTL). Using the VCCTL, a user may create starting microstructures of cement (gypsum, fly ash, etc.) particles in water, hydrate the
