Quantifying Usability: The Industry Usability Reporting Project

July 1, 2002
Author(s)
Jean C. Scholtz, Emile L. Morse, Sharon J. Laskowski, A Wishansky, K Butler
The paper describes the Common Industry format (CIF) developed in the Industry Usability Reporting Project (IUSR), which is now an ANSI standard. Four pilot studies conducted to verify the usefulness of the CIF are also described.

Quantitating Fluorescence Intensity From Fluorophores: Practical Use of MESF Values

July 1, 2002
Author(s)
Lili Wang, Adolfas K. Gaigalas, F Abassi, G E. Marti, R F. Vogt, A Schwarz
The present work uses fluorescein as the model fluorophore and points out critical steps in the use of MESF (Molecules of Equivalent Soluble Fluorophores) values for quantitative flow cytomeric measurements. It has been found that the emission spectrum

Quantitation of Polymer End Groups Using MALDI TOF MS

July 1, 2002
Author(s)
A P. Weaver, Charles M. Guttman, Kathleen M. Flynn
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) has been employed to analyze polystryrene mixtures of molecular mass ca. 4000u. The component polymers of thes mixtures are identical except for their end groups

Rapid, Remote, Automated Card Sorting using WebCAT

July 1, 2002
Author(s)
Emile L. Morse
WebCAT is a rapid, remote, and automated method for performing card sorting. WebCAT, a tool from the NIST Web Metrics Testbed, provides a web-based interface for performing card sorting. Its three major parts are: interface for experimental design, drag

Reliability Improvements in Repair Welding of High Strength Steels

July 1, 2002
Author(s)
Ivan Samardzic, Thomas A. Siewert
Engineers often have to deal with repair of weldments after they have been put into service. Here, the concern is that the service environment may have changed the structure, indepent of whether the problems originated during the initial construction (cold

Responding to National Needs, 1994 - 2001: Supplement to Appendices

July 1, 2002
Author(s)
Diane Cunningham, P J. Deutsch, J M. Ives, S L. Kelley, Keith R. Martin, J V. Norris
Information contained in this document updates and expands the data presented in the Appendices of the report Responding to National Needs: The National Bureau of Standards Becomes the National Institute of Standards and Technology 1969-1994, by James F

Scanning Electron Microscope Analog of Scatterometry

July 1, 2002
Author(s)
John S. Villarrubia, Andras Vladar, J R. Lowney, Michael T. Postek
Optical scatterometry has attracted a great deal of interest for linewidth measurement due to its high repeatability and capability of measuring sidewall shape. We have developed an analogous and complementary technique for the scanning electron microscope

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

July 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

Some Issues in Particle Size and Size Distribution Characterization of Powders

July 1, 2002
Author(s)
Ajitkumar Jillavenkatesa, James F. Kelly, S J. Dapkunas
Size and size distribution measurement of powders are conducted using different techniques of size analysis.Underlying all these techniques are certain fundamental issues that influence the accuracy and reproducibility ofthe results. A thorough

The Challenge of Nanometrology

July 1, 2002
Author(s)
Michael T. Postek
The promise and challenge of nanotechnology is immense. The National Nanotechnology Initiative provides an opportunity to develop a new technological base for U.S. Industry. Nanometrology is the basis of the new measurement methods that must be developed

The Common Industry Format (CIF) is Now an ANSI/INCITS Standard

July 1, 2002
Author(s)
Sharon J. Laskowski, Emile L. Morse
The IUSR (Industry USability Reporting) project, led by NIST (National Institute of Standards and Technology), is developing approaches for increasing the visibility of software usability. Participants are from prominent software supplier and customer
