Autonomy Levels for Unmanned Systems (ALFUS) Framework: An Update

April 4, 2005
Author(s)
Hui-Min Huang, K Pavek, James S. Albus, Elena R. Messina
The initial construct of the framework for the Autonomy Levels of Unmanned Systems (ALFUS) was presented in the 2004 SPIE Defense and Security Symposium. This paper describes the continuing development effort and further accomplishments made by the Ad Hoc

Comparison of SEM and HRTEM CD-Measurements Extracted From Monocrystalline Tes-Structures Having Feature Linewidths From 40 nm to 240 nm

April 4, 2005
Author(s)
W Tan, Robert Allen, Michael W. Cresswell, Christine E. Murabito, B C. Park, Ronald G. Dixson, William F. Guthrie
CD measurements have been extracted from SEM and HRTEM images of the same set of monocrystalline silicon features having linewidths between 40 and 200 nm. The silicon features are incorporated into a new test structure which has been designed to facilitate

Flammability of Polymer Clay Nanocomposites Consortium:Final Report

April 4, 2005
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, A B. Morgan, Rick D. Davis, Richard H. Harris Jr., L D. Brassell
In 1997 NIST reported that polymer layered-silicate (clay) nanocomposites exhibit reduced flammability, in the form of reduced heat release rate (HRR). The unique character of this new approach to flame retard polymeric materials was the dual benefit of

Metrology for High-Voltage, High-Speed Silicon-Carbide Power Devices

April 4, 2005
Author(s)
Allen R. Hefner Jr., David W. Berning, Colleen E. Hood
Performance metrics and test instrumentation needs for emerging high-voltage, high-speed SiC power devices are described. Unique power device and package thermal measurement test systems and parameter extraction methods are introduced, and applied to

Out-of-Plane Polarimetric Imaging of Skin: Surface and Subsurface Effects

April 4, 2005
Author(s)
J C. Ramella-Roman, D Duncan, Thomas A. Germer
True borders of certain skin cancers are hard to detect by the human eye. For this reason, techniques such as polarized light imaging have been used to enhance skin cancer contrast before Mohs surgery procedures. In standard polarized light imaging the

An Overview and Analysis of PDA Forensic Tools

April 2, 2005
Author(s)
Wayne Jansen, Richard Ayers
Mobile handheld devices are becoming evermore affordable and commonplace in society. When they are involved in a security incident or crime, forensic specialists require tools that allow proper extraction and speedy examination of any digital evidence

Standards for Validation of Cancer Biomarkers

April 2, 2005
Author(s)
Catherine D. O'Connell, Donald H. Atha, J P. Jakupciak
Over the past 10 years, DNA testing to identify disease associated mutations and specific organisms, which represent public health and safety concerns, have become major targets for laboratory testing. RNA testing is also emerging for gene expression, both

2-D Imaging of Temperature in CF 4 Plasmas

April 1, 2005
Author(s)
Kristen L. Steffens, Mark A. Sobolewski
Two-dimensional maps of rotational temperature were determined in CF4 plasmas using planar laser-induced fluorescence of CF. Experiments were performed in a capacitively-coupled, parallel plate plasma reactor at pressures from 200mTorr (26.7Pa) to 800mTorr

A Model Driven Standards Process

April 1, 2005
Author(s)
Arthur Griesser
Explains how and why UML models fit into a robust formal standardization process based on the best practices of software development.

A Simple Transfer-Optics System for an Extreme-Ultraviolet Synchrotron Beamline

April 1, 2005
Author(s)
Charles S. Tarrio, Steven E. Grantham, Robert E. Vest, K Liu
Beamlines at synchrotron radiation facilities often have interchangeable endstations to allow several different experiments to use the output of a single monochromator. However, for endstations that are sufficiently large, this is not possible. We have

An Architecture for Semantic Enterprise Application Integration Standards

April 1, 2005
Author(s)
Nenad Anicic, Nenad Ivezic, Albert T. Jones
Large, industry-wide interoperability projects use syntax-based standards approaches to accomplish interoperable data exchange among enterprise applications. We are investigating Semantic Web to advance these approaches. In this paper, we describe an

Beyond English

April 1, 2005
Author(s)
Donna K. Harman
This chapter summarizes TREC work on retrieval for language other than English. TREC has explored a variety of tasks including both single language tasks (for example, retrieving Chinese documents using Chinese queries) and cross-language tasks (such as

Calibrated 200 GHz Waveform Measurement

April 1, 2005
Author(s)
Dylan Williams, Paul D. Hale, Tracy S. Clement
We develop a method for mismatch-correcting temporal waveforms measured with a high-speed electro-optic sampling system. The new calibration characterizes the source in both the time and frequency domains, and accounts for all impedances and multiple
