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

Round Robin Study of Total Heat Flux Gauge Calibration at Fire Laboratories

October 1, 2004
Author(s)
William M. Pitts, A V. Murthy, J L. de Ris, J R. Filtz, K Nyard, D Smith, I Wetterlund
Total heat flux gauges are widely employed in fire research and fire testing laboratories. Several fire laboratories have developed systems for calibrating these gauges. There are major differences between these calibration facilities, and prior to this

Securely Connecting the World with Cyber Security Standards

October 1, 2004
Author(s)
Alicia Clay Jones, Michael Hogan
This paper focuses on some of the key roles that cyber security standards play in securely connecting our cyber world. Cyber security standards can be categorized as technical, management, or testing standards. All three types of standards are necessary to

Securing Voice Over Internet Protocol (IP) Networks

October 1, 2004
Author(s)
Thomas J. Walsh, David R. Kuhn
Voice over IP - the transmission of voice over traditional packet-switched IP networks - is one of the hottest trends in telecommunications. As with any new technology, VOIP introduces both opportunities and problems. Lower cost and greater flexibility are

Shape Analysis of a Reference Cement

October 1, 2004
Author(s)
Edward J. Garboczi, Jeffrey W. Bullard
Recently, techniques for acquiring, analyzing, and using 3-D shape information for aggregates (sand, gravel) have been developed and demonstrated. These mathematical techniques, based on spherical harmonic coefficient analysis, have been applied to x-ray
