Wetting Behavior on Microscale Wrinkled Surfaces

January 1, 2007
Author(s)
Jun Y. Chung, Christopher M. Stafford
We present a systematic study of the wetting behavior on the anisotropic microstructure having a simple sinusoidal profile. The micro-patterned surface was generated by using the buckling-based technique, and its wetting properties were examined by contact

Widefield Light Microscopy Method for High Resolution and Quantum Dot Spectral Studies

January 1, 2007
Author(s)
Cynthia J. Zeissler, Keana C. Scott, Richard D. Holbrook, Peter E. Barker, Yan Xiao
We are exploring methods to achieve 3D 200 nm resolution multispectral imaging with an ordinary inexpensive widefield microscope using incoherent white light sources and an electronically tunable filter. In this work, the capabilities were applied to

Will Future Measurement Needs for the Semiconductor Industry Be Met?

January 1, 2007
Author(s)
Herbert S. Bennett, Alain C. Diebold, C. M. Garner
We present an assessment of the state of the nation''s measurement system in its ability to meet the metrology needs of the semiconductor industry. Lacking an acceptable metric for the assessing the health of metrology for the semiconductor industry, we

Electromagnetics Division: Programs, Activities, and Accomplishments

December 31, 2006
Author(s)
Ronald B. Goldfarb
The Electromagnetics Division is a critical national resource for a wide range of customers. U.S. industry is the primary customer both for the division's measurement services and for technical support on the test and measurement methodology necessary for

Role-Based Access Control, Second Edition

December 31, 2006
Author(s)
David F. Ferraiolo, David R. Kuhn, Ramaswamy Chandramouli
[ISBN-13: 978-1-59693-113-8] This newly revised edition of "Role-Based Access Control" offers the latest details on a security model aimed at reducing the cost and complexity of security administration for large networked applications. The second edition

A practical guide to the CIF:usability measurements

December 29, 2006
Author(s)
Mary F. Theofanos, Brian C. Stanton, Nigel Bevan
Using the Common Industry Format ( CIF) to specify usability measures can positively influence the development process. The CIF remains inherently flexible and adaptable?empowering the practitioner to identify success criteria specific to the application

Common Vulnerability Scoring System

December 29, 2006
Author(s)
Peter M. Mell, Karen Kent Scarfone, Sasha Romanosky
Organizations struggle to assess the relative importance of software vulnerabilities across disparate hardware and software platforms. They must prioritize vulnerabilities and remediate those that pose the greatest risk. However, most software vendors and

Electrical breakdown in the microscale: testing the standard theory

December 29, 2006
Author(s)
Emmanouel S. Hourdakis, Garnett W. Bryant, Neil M. Zimmerman
We present breakdown voltage measurement data in air taken with a technique we recently developed. The data suggests that below 10 ?m of electrode separation the dominant effect is field emission of electrons from the electrodes. Analyzing the data in that

Intelligent Unmanned Ground Vehicle Navigation via Information Evaluation

December 29, 2006
Author(s)
Rajmohan Madhavan, Elena R. Messina
Sensor-centric navigation of Unmanned Ground Vehicles (UGVs) operating in rugged and expansive terrains requires the competency to evaluate the utility of sensor information such that it results in intelligent behavior of the vehicles. Highly imperfect

Learning in a Hierarchical Control System: 4D/RCS in the DARPA LAGR Program

December 29, 2006
Author(s)
James S. Albus, Roger V. Bostelman, Tommy Chang, Tsai H. Hong, William P. Shackleford, Michael O. Shneier
The Defense Applied Research Projects Agency (DARPA) Learning Applied to Ground Vehicles (LAGR) program aims to develop algorithms for autonomous vehicle navigation that learn how to operate in com-plex terrain. Over many years, the National Institute of

Observation of the Radiative Decay Mode of the Free Neutron

December 29, 2006
Author(s)
Jeffrey S. Nico, Maynard S. Dewey, Thomas R. Gentile, Hans P. Mumm, Alan K. Thompson, B Fisher, I Kremsky, Fred E. Wietfeldt, T E. Chupp, R Cooper, E Beise, K G. Kiriluk, J Byrne, Kevin J. Coakley
The theory of quantum electrodynamics predicts that beta decay of the neutron into a proton, electron, and antineutrino should be accompanied by a continuous spectrum of soft photons. While this inner bremsstrahlung branch has been previously measured in

PIV Card to Reader Interoperability Guidelines

December 29, 2006
Author(s)
James F. Dray Jr., April Giles, Michael Kelley, Ramaswamy Chandramouli
The purpose of this document is to present recommendations for Personal Identity Verification (PIV) card readers in the area of performance and communications characteristics to foster interoperability. This document is not intended to re-state or

Toward a Computational Theory of Mind

December 29, 2006
Author(s)
James S. Albus
Scientific knowledge of the brain and technology of intelligent systems have developed to a point where a computational theory of mind is feasible. This paper briefly describes the RCS (Real-time Control System) reference model architecture that has been
