NIST CFTT: Testing Disk Imaging Tools

August 1, 2002
Author(s)
James R. Lyle
There is a critical need in the law enforcement community to ensure the reliability of computer forensic tools. A capability is required to ensure that forensic software tools consistently produce accurate and objective test results. The goal of the

Numerical Modeling of an Integrating Sphere Radiation Source

August 1, 2002
Author(s)
A Prokhorov, Leonard Hanssen
Integrating spheres are often used as calibration sources providing uniform radiance within solid angle and/or uniform irradiance at a distance. The best performance in such a system can be achieved if one is able to evaluate as well as predict important

Optimizing the Covalent Cationization Method for the Mass Spectrometry of Polyolefins

August 1, 2002
Author(s)
Sheng Lin-Gibson, L Brunner, David L. VanderHart, Barry J. Bauer, B M. Fanconi, Charles M. Guttman, William E. Wallace
Previously a new method was introduced for the mass spectrometry of polyolefins whereby an organic cation is covalently bonded to the polymer to produce the necessary ionization for the creation of intact gas?phase macromolecules by matrix-assisted laser

Phase Behavior in Polyolefin Blend

August 1, 2002
Author(s)
G Matsuba, K Shimizu, Haonan Wang, Z G. Wang, Charles C. Han
The phase behavior in copolymer blend of PEH(60)PEB(40) blend has been studied by phase contrast optical microscopy within the two phase region. In single quench, the interconnected biocontinuous structure was observed in molten state. The interconnected

Photoassociation in a Bose-Einstein Condensate

August 1, 2002
Author(s)
Paul D. Lett
Two colliding atoms can absorb a photon and be photoassociated into an excited, diatomic molecule, NIST researchers investigated the fundamental rate at which this process can take place in a Bose-Einstein condensate (BEC) and demonstrated that simple

Polymer Science at the NIST Combinatorial Methods Center

August 1, 2002
Author(s)
Cher H. Davis, Kathryn L. Beers, Aaron M. Forster, Christopher M. Stafford, A P. Smith, C Harrison, Weiping Zhang, Alamgir Karim, Eric J. Amis
The measurements, standards, and test methods developed by NIST, in partnership with other organizations, often help unlock the potential of new discoveries and budding technologies. Combinatorial methods are a textbook example. These emerging tools can

Quadruple Suspension Design for Advanced LIGO

August 1, 2002
Author(s)
N A. Robertson, G Cagnoli, D R M Crooks, E Elliffe, J E. Faller, P Fritschel, S Gossler, A Grant, A Heptonstall, Jon T. Hougen, H Luck, R Mittleman, R-Loyd` Perreur-Loyd, M V. Plissi, S Rowan, D H. Shoemaker, P Sneddon, K A. Strain, C I. Torrie, H Ward, P Willems
In this paper, we describe the conceptual design for the suspension system for the test masses for Advanced LIGO, the planned upgrade to LIGO, the US Laser Interferometric Gravitational-wave Observatory. The design is based on the triple pendulum design

Rate Effects in Critical Loads for Radial Cracking in Ceramic Coatings

August 1, 2002
Author(s)
C S. Lee, D H. Kim, J Sanchez, P Miranda, Antonia Pajares, Brian R. Lawn
Rate effects in the Hertzian contact loading of model glass/polycarbonate and silicon/polycarbonate bilayers bonded by epoxy adhesive are examined. Glass is used because of its high susceptibility to slow crack growth, making this conventional contribution

Reaction Front Induced Roughness in Chemically Amplified Photoresists

August 1, 2002
Author(s)
Vivek Prabhu, Ronald L. Jones, Eric K. Lin, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Christopher Soles, Wen-Li Wu, D L. Goldfarb, M Angelopoulos
We have examined, with tapping mode atomic force microscopy(AFM), the effect of post-exposure bake times and developer on surface roughness using model bilayer interfaces of deuterium-labeled poly(tert-butyloxycarbonyloxy styrene) and poly(hydroxystyrene)

Rheology of Poly(ethylene oxide) Clay Solutions

August 1, 2002
Author(s)
Sheng Lin-Gibson, G Schmidt, Jai A. Pathak, Charles C. Han
Poly(ethylene oxide) and Laponite, a synthetic hectorite clay, form highly viscoelastic solutions in water. Above a certain clay concentration, these solutions can be described as physical crosslinked networks where clay platelets undergo equilibrium

Setup and Test Procedures dd (GNU Fileutils) 4.0.36 Forensic Tests

August 1, 2002
Author(s)
James R. Lyle
This document describes the testing of dd (GNU fileutils) 4.0.36 as a disk imaging tool on a Linux platform. The Linux version used was Linux version 2.4.2-2 (Red Hat Linux 7.1 2.96-79). The test cases that were applied are described in Disk Imaging Tool

Simulation System Modeling for Mass Customization Manufacturing

August 1, 2002
Author(s)
Guixiu Qiao, Charles R. McLean, Frank H. Riddick
Emerging rapidly as a new paradigm of the 21st century, Mass Customization Manufacturing (MCM) systems possess some special characteristics that make the modeling of such systems extremely difficult. These characteristics include concurrency
