Building an Information Technology Security Awareness and Training Program

October 1, 2003
Author(s)
Mark Wilson, Joan Hash
NIST Special Publication 800-50, Building An Information Technology Security Awareness and Training Program, provides guidance for building an effective information technology (IT) security program and supports requirements specified in the Federal

Calibration of Radiation Thermometers in Rapid Thermal Processing Tools Using Si Wafers with Thin Film Thermocouples

October 1, 2003
Author(s)
Kenneth G. Kreider, William A. Kimes, Christopher W. Meyer, Dean C. Ripple, Benjamin K. Tsai, D H. Chen, D P. DeWitt
Rapid thermal processing (RTP) tools are currently monitored and controlled with lightpipe radiation thermometers (LPRTs) which have been calibrated with thermocouple instrumented wafers. We have developed a thin-film thermocouple wafer that enables more

Cluster-Assembled Materials Based on Na 6 Pb

October 1, 2003
Author(s)
J Zhao, Rui-Hua Xie
In experimental mass spectra of lead-sodium mixed clusters, an exceptionally abundant and stable Na 6Pb cluster has been discovered. [C. H. Yeretzian et al., Chem Phys. Lett 237, 334 (1995)]. By using first-principles calculations, several cluster

Collaborative Evolution of Process Plans in Distributed Manufacturing

October 1, 2003
Author(s)
Boonserm Kulvatunyou, Jungyub Woo, Hyunbo Cho
Global production has become a new trend in the today?s competitive business environment in pursuit of lower cost, shorter time-to-market, and better quality. This forces manufacturing enterprises to separate design houses and manufacturing facilities. The

Comment On 'General Principles for the Definition of the Base Units in the SI'

October 1, 2003
Author(s)
Michael R. Moldover, Dean C. Ripple
Recently, Kose et al. proposed general principles that should guide any future discussions regarding the redefinition of the SI base units and they illustrated their principles with an example of a revised SI. Part of their example (redefinition of the

Computer Forensics Tool Testing (CFTT)

October 1, 2003
Author(s)
James R. Lyle
The National Software Reference Library (NSRL) of the U.S. National Institute of Standards and Technology (NIST) collects software from various sources and publishes file profiles computed from this software (such as MD5 and SHA-1 hashes) as a Reference

Databases for Computational Thermodynamics and Diffusion Modeling

October 1, 2003
Author(s)
Ursula R. Kattner, J E. Morral, William J. Boettinger
tabases for computational thermodynamics and diffusion modeling can be applied to the prediction of phase diagrams and microstructural evolution. These can be used for alloy and process design as well as to improve modeling capabilities that would decrease

Deconvolving LADAR Images Of Bar Codes for Construction Site Object Recognition

October 1, 2003
Author(s)
David E. Gilsinn, Geraldine S. Cheok, Dianne M. O'Leary
This report discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADAR optics. The first part of this report describes the experimental data collection of several bar code images along with

Design and Performance of Capping Layers for Extreme-Ulatraviolet Multilayer Mirrors

October 1, 2003
Author(s)
Sasa Bajt, H N. Chapman, Nhan Nguyen, J Alameda, J C. Robinson, M Malinowski, E Gullikson, Andrew Aquila, Charles Tarrio, Steven Grantham
Multilayer lifetime has emerged as one of the major issues for the commercialization of extreme-ultraviolet lithography (EUVL). We describe the performance of an oxidation-resistant capping layer of Ru atop multilayers that results in a reflectivity above

Design and Workspace Analysis of a 6-6 Cable-Suspended Parallel Robot

October 1, 2003
Author(s)
H C. Pusey, A Fattah, S K. Agrawal, Elena R. Messina, Adam S. Jacoff
In this paper, we study the design and workspace of a 6-6 cable-suspended parallel robot. The workspace volume is characterized as the set of points where the centroid of the MP (MP) can reach with tensions in all suspension cables at a constant

Development of an Optical Fiber-Based Moisture Sensor for Building Envelopes

October 1, 2003
Author(s)
William M. Healy, S Luo, M Evans, A Sucheta, Y Liu
Optical fiber-based moisture sensors have been developed to help detect moisture problems in building envelopes. The sensors are created with a coating on a long period grating that is written onto optical fiber. As the coating absorbs moisture from its

Droplet-String Deformation and Stability During Micro-Confined Shear Flow

October 1, 2003
Author(s)
Jai A. Pathak, Kalman D. Migler
We have performed experiments on model emulsions of polyisobutylene (PIB) and poly(dimethylsiloxane) (PDMS) to quantify the effect of confinement on deformation and stability of droplets and strings (threads) under flow. It is known from some of our

Electrostatic Influence on Ion Transport through the alpha HL Channel

October 1, 2003
Author(s)
M Misakian, John J. Kasianowicz
The current-voltage relationship of a single Staphylococcus aureus α-hemolysin(αHL) channel is nonlinear, rectifying, and depends on the bulk pH and the ionic strength. The data are described qualitatively by a simple one-dimensional Nernst-Planck analysis
