Ground and First Excited Torsional States of Acetamide

October 1, 2004
Author(s)
Vadim V. Ilyushin, E A. Alekseev, S K. Dyubko, I Kleiner, Jon T. Hougen
Recent progress in measuring, assigning and fitting the millimeter wave spectrum of the ground, first and second excited torsional states of the acetamide molecule CH3CONH2 is reported. New measurements of the acetamide spectrum have been carried out

Guide to Public Safety Applications of Wireless Technology

October 1, 2004
Author(s)
Leonard E. Miller
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

High-contrast dark resonances in s+ -s- optical field

October 1, 2004
Author(s)
S. Kargapoltsev, John Kitching, Leo W. Hollberg, A. V. Taichenachev, V L. Velichanski, V. I. Yudin
For application to atomics clocks, it is important to have large amplitude and small width of the CPT resonance. In this paper, we show that the contrast and amplitude of the dark resonance can be significantly increased in a miniature buffer gas cell by

Horizontal Growth and In Situ Assembly of Oriented Zinc Oxide Nanowires

October 1, 2004
Author(s)
Babak Nikoobakht, Chris A. Michaels, Stephan J. Stranick, Mark D. Vaudin
The positioning and directed assembly of semiconductor nanowires (NWs) is of considerable current interest for bottom-up approaches to the engineering of intricate structures from nanoscale building blocks. We report a horizontal growth mode for ZnO NWs on

Integer representation of decimal numbers for exact computations

October 1, 2004
Author(s)
Javier Bernal, Christoph J. Witzgall
A scheme is presented and software is documented for representing as integers input decimal numbers that have been stored in a computer as double precision floating point numbers and for carrying out multiplications, additions and subtractions based on

Lattice Dynamics in PbMg1/3Nb2/3O3

October 1, 2004
Author(s)
S A. Prosandeev, Eric J. Cockayne, Benjamin P. Burton, S Kamba, J Petzelt, Yu Yuzyuk, R S. Katiyar, S B. Vakhrushev

Modelling Polycrystalline Solidification Using Phase Field Theory

October 1, 2004
Author(s)
L Granasy, T Pusztai, James A. Warren
We review recent advances made in phase field modelling of polycrystalline solidification. Areas covered include the development of theory from early approaches that allow for only a few crystal orientations, to the latest models relying on a continuous

Nature and Measure of Entanglement in Quantum Phase Transactions

October 1, 2004
Author(s)
Rolando Somma, Gerardo Ortiz, Howard Barnum, Emanuel Knill, Lorenza Viola
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

NIST/XDS Text Kit, Version 1.0, 1.1 & 1.2

October 1, 2004
Author(s)
William J. Majurski, A Mccaffrey, Mary T. Laamanen
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

Operator Interventions in Autonomous Off-Road Driving: Effects of Terrain

October 1, 2004
Author(s)
Jean C. Scholtz, Brian Antonishek, J D. Young
We participated in a field study in two terrains, arid and wooded, and compared the number and type of interventions the operators made. We also analyzed the amount of time needed to gain situation awareness in the different terrains.

Performance Evaluation of Road Detection and Following Systems

October 1, 2004
Author(s)
Tsai Hong Hong, A Takeucki, Mike Foedisch, Michael O. Shneier
We describe a methodology for evaluating algorithms to provide quantitative information about how well road detection and road following algorithms perform. The approach relies on generating a set of standard data sets annotated with ground truth. We

Probing the Origins and Control of Shrinkage Stress in Dental Resin-Composites. II. Novel Methods of Simultaneous Measurement of Polymerization Shrinkage Stress and Conversion

October 1, 2004
Author(s)
H Lu, J W. Stansbury, Sabine H. Dickens, F Eichmiller, Christopher N. Bowman
In this study, we have probed the interrelationships between polymerization shrinkage stress development and the polymerization progress with a novel experimental technique. This technique is capable of measuring the shrinkage stress, using a cantilever

Resource Planning and Bandwidth Allocation in Hybrid Fiber-Coax Residential Networks

October 1, 2004
Author(s)
David W. Griffith, Kotikalapudi Sriram, L Krivulina, 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
