Voting Issues Discussion, IEEE 802.21-05-217-01

January 1, 2005
Author(s)
Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Camera Calibration for a Manufacturing Inspectio Workstation

December 31, 2004
Author(s)
T M. Tsai
A CCD camera mounted on a manufacturing part inspection workstation is calibrated for measuring 3D part geometry. It is calibrated by using computer algorithms to analyze data collected from a pre-designed calibration image pattern. The calibration image

Coordinated Motion Control for Industrial Boomlifts

December 31, 2004
Author(s)
Richard J. Norcross, Robert Bunch
This project coordinated the motions of the individual actuators on an industrial boomlift. The work was funded by the U.S. Navy ManTech Program to augment the Navy's development of an environmentally friendly paint stripper. The project successfully

Dynamic Modeling and Robust Controller Design of a Two-Stage Parallel Cable Robot

December 31, 2004
Author(s)
S R. Oh, K K. Mankala, S K. Agrawal, James S. Albus
Able robots have been extensively used for the loading and unloading of cargo in shipping industries. In this paper, we look at a two stage cable robot, i.e., a cable robot with two moving platforms connected in series. The sea condition introduces

Empirical Comparison of Predictive Models for Mobile Agents

December 31, 2004
Author(s)
A E. Henninger, Rajmohan (. Madhavan
The need to predict an agent's intents or future actions has been well documented in multi-agent system's literature and has been motivated by both systematically-practical and psychologically-principled concerns. However, little effort has focused on the

Limits of Storage in Magnetic Materials

December 31, 2004
Author(s)
Thomas J. Silva
I summarize what is currently known about how thermal effects limit the storage capacity of magnetic disk drives. The physics of thermal fluctuations in magnetic materials is treated in some detail, though the essential points are covered in a tutorial

Nanoscale Elastic-Property Mapping with Contact-Resonance-Frequency AFM

December 31, 2004
Author(s)
Donna C. Hurley, Tony B. Kos, Paul Rice
We describe dynamic atomic force microscopy (AFM) techniques to map the nanoscale elastic properties of surfaces, thin films, and nanostructures. Our approach is based on atomic force acoustic microscopy (AFAM) methods that have previously been used for

NIST Handbook 133: Checking the Net Contents of Packaged Goods (2004 Ed.)

December 31, 2004
Author(s)
Linda D. Crown, Kenneth S. Butcher
This handbook has been prepared as a procedural guide for the compliance testing of net content statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance of the results of the packaging, distribution, and

Policy Issues for R&D Investment in a Knowledge-Based Economy

December 31, 2004
Author(s)
Gregory C. Tassey
The ‘‘Internet Revolution’’ induced an unbalanced perspective on future economic growth strategies. Because information technology (IT) largely constitutes an infrastructure upon which other economic activity is based, its economic role is to facilitate

Self-contained automated construction deposition system

December 31, 2004
Author(s)
R L. Williams, James S. Albus, Roger V. Bostelman
This article presents a novel autonomous system concept for automated construction of houses and other buildings via deposition of concrete and similar materials. The overall system consists o f a novel cable-suspended mobility subsystem (a selfcontained

Submillimeter and THz Detection of Chemical-Warfare Agents in Air

December 31, 2004
Author(s)
Vyacheslav B. Podobedov, R J. Lavrich, T M. Korter, Gerald T. Fraser, David F. Plusquellic, A C. Samuels
Experimental measurements and theoretical calculations were performed to assess the potential for using continuous-wave submillimeter and THz (far-infrared) linear-absorption spectroscopies to detect chemical-warfare agents in air at ambient temperatures
