Summary of ISO/TC 201 Technical Report: ISO/TR 19319: 2003 Surface Chemical Analysis Auger Electron Spectroscopy and X-Ray Photoelectron Spectroscopy Determination of Lateral Resolution, Analysis Area, and Sample Area Viewed by the Analyser

July 1, 2004
Author(s)
Cedric J. Powell
ISO Technical Report 19319 contains information on the determination of lateral resolution, analysis area, and sample area viewed by the analyser in surface analyses by Auger-electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). This

Synthesis and Characterization of PEG Dimethacrylates and their Hydrogels

July 1, 2004
Author(s)
Sheng Lin-Gibson, S Bencherif, James A. Cooper, S Wetzel, Joseph M. Antonucci, Brandon M. Vogel, F Horkay, N. R. Washburn
Facile synthesis and detailed characterization of photo-polymerizable and biocompatible poly(ethylene glycol) dimethacrylates (PEGDM) and poly(ethylene glycol) urethane-dimethacrylates (PEGUDM) are described. Poly(ethylene glycol)s of various molecular

Test of CD-SEM Shape-Sensitive Linewidth Measurement

July 1, 2004
Author(s)
John S. Villarrubia, Andras Vladar, Michael T. Postek
In a model-based library (MBL) approach to scanning electron microscope (SEM) linewidth measurement, a library of simulation results for a range of lineshapes is searched for a match to the measured image of the unknown line. Compared to standard

The Effects of Human Variation in DUC Summarization Evaluation

July 1, 2004
Author(s)
Donna K. Harman, Paul D. Over
There is a long history of research in automatic text summarization systems by both the text retrieval and the natural language processing communities, but evaluation of such systems' output has always presented problems. One critical problem remains how

Thermally-Treated Clay as a Stationary Phase in Liquid Chromatography

July 1, 2004
Author(s)
K E. Miller, Thomas J. Bruno
Spray-dried, spherical synthetic hectorite particles are thermally-treated andised as adsorbent materials in reversed-phase high pressure liquid chromatography. The retention of a series of mono- and di-substituted aromatimompounds is evaluated to study

Triangular Meshing and Volume Determination

July 1, 2004
Author(s)
Christoph J. Witzgall, Geraldine Cheok
Parametric studies are reported for investigating the feasibility and accuracy of calculating volumes from LADAR scans of artifacts. The TIN (=Triangulated Irregular Network) technique was employed to construct surfaces on which the volume calculation was

Writing Quality Specifications

July 1, 2004
Author(s)
Mark Skall
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

Fingerprint Vendor Technology Evaluation 2003: Summary of Results and Analysis Report

June 30, 2004
Author(s)
Charles L. Wilson, Patrick J. Grother, Ross J. Micheals, S C. Otto, Craig I. Watson, R. A. Hicklin, H Korves, Brad Ulery, M Zoepfl
The Fingerprint Vendor Technology Evaluation (FpVTE) 2003 was conducted to evaluate the accuracy of fingerprint matching, identification, and verification systems. The FpVTE is one of the tests that NIST has conducted in order to fulfill part of its

1 A and 120 mA Thin Film Multijunction Thermal Converters

June 28, 2004
Author(s)
H. Laiz, Thomas F. Wunsch, Joseph R. Kinard Jr., Thomas E. Lipe Jr.
We report on the development of thin-film multijunction thermal converters for the measurement of ac current without relying on parallel current shunts. The materials and designs chosen for these devices have been optimized to provide high accuracy over a

Silicon-Based Tunable-Barrier Single Charge Sources

June 27, 2004
Author(s)
Neil M. Zimmerman
We have demonstrated the operation of, and are assessing theoretically and experimentally the error rates of, silicon-based single-electron turnstiles, pumps, and CCDs. These devices are conceptually very similar to the metal-based single-electron pumps
