Continuous light shift correction in modualted coherent opoulation trapping clocks

October 13, 2006
Author(s)
V Shah, Vladislav Gerginov, P Schwindt, Svenja A. Knappe, Leo W. Hollberg, John E. Kitching
We demonstrate a simple technique to significantly improve the long term frequency stability of atomic clocks based on coherent population trapping (CPT). In this technique, the CPT feilds are created by a modulated diode laser and a slow servo is used to

Automatic Message Classification

October 11, 2006
Author(s)
Arthur Griesser
Rising automation means fewer humans, maintaining more equipment, which is exchanging more information. This information torrent is expected to increase even further, with the implementation of advanced process control and new information transfer

New Global Communication Process in Thermodynamics: Impact on Quality of Published Experimental Data

October 11, 2006
Author(s)
Michael D. Frenkel, Robert D. Chirico, Vladimir Diky, Chris D. Muzny, Qian Dong, K N. Marsh, John H. Dymond, William A. Wakeham, Stephen E. Stein, Erich Koenigsberger, Anthony R. Goodwin, Joe W. Magee, Michiel Thijssen, William M. Haynes, Suphat Watanasiri, Marco Satyro, Martin Schmidt, Andrew I. Johns, Gary R. Hardin
Thermodynamic data often represent a key resource in the search for new relationships between properties of chemical systems that constitutes the basis of the scientific discovery process. In addition, thermodynamic information is critical for development

Cationic Surfactants for the Control of Overfill Bumps in Cu Superfilling

October 10, 2006
Author(s)
Soo K. Kim, Daniel Josell, Thomas P. Moffat
Electroanalytical measurements and feature filling experiments have been conducted to study the effect of dodecyltrimethylammonium chloride (DTAC), a quaternary ammonium cationic surfactant, on Cu deposition in the presence of various combinations of

Determination of Levoglucosan in Particulate Matter Reference Materials

October 10, 2006
Author(s)
R Larsen, III, Michele M. Schantz, Stephen Wise
Source identification is critical for the effective management of air pollution. The ratio of levoglucosan (1,6-anhydro-B-D-glucose) to organic carbon has been used to identify and quantify the contribution of biomass combustion to the organic carbon

RF, Analog, and Mixed Signal Technologies for Communication ICs - An ITRS Perspective

October 10, 2006
Author(s)
Margaret Huang, Herbert S. Bennett, Julio Costa, Peter Cotrell, Anthony A. Immorlica, Jan-Erik Meuller, Charles E. Weitzel, Marco Racaneli, Hisashi Schichijo, Bin Zhao
The International Technology Roadmap for Semiconductor (ITRS) Radio Frequency and Analog/Mixed-Signal (RF and AMS) Wireless Technology Working Group (TWG) addresses device technologies for wireless communications covering both silicon-based and III-V

An Ontology of Identity Credentials Part 1: Background and Formulation

October 6, 2006
Author(s)
William I. MacGregor
The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology (NIST) promotes the U.S. economy and public welfare by providing technical leadership for the Nation s measurement and standards infrastructure. ITL develops

Applications of a 3D Range Camera Towards Healthcare Mobility Aids

October 3, 2006
Author(s)
Roger V. Bostelman, Peter Russo, James S. Albus, Tsai Hong Hong, Rajmohan Madhavan
The National Institute of Standards and Technology (NIST) has recently studied a new 3D range camera for use on mobile robots. These robots have potential applications in manufacturing, healthcare and perhaps several other service related areas beyond the

CONTAM 2.4 User Guide and Program Documentation

October 3, 2006
Author(s)
George Walton, William S. Dols
This manual describes the computer program CONTAM version 2.3 developed by NIST. CONTAM is a multizone indoor air quality and ventilation analysis program designed to help you determine: airflows and pressures infiltration, exfiltration, and room-to-room
