A New Technique for Evaluating Diffusion Mobility Parameters

July 7, 2005
Author(s)
Carelyn E. Campbell
The development and evaluation of a multicomponent diffusion mobility database for Ni-rich alloys are reviewed. In an effort to more directly evaluate the mobility parameters in the database, a method for optimizing the mobility parameters as a function of

CCQM-K27-Subsequent: Key Comparison (subsequent) for the Determination of Ethanol in Aqueous Matrix

July 7, 2005
Author(s)
Michele M. Schantz, David L. Duewer, Reenie M. Parris, Willie E. May, M Archer, C Mussell, D Carter, L A. Konopelko, Y A. Kustikov, A I. Krylov, O V. Fatina
Ethanol is important both forensically ('drunk driving' or driving while under the influence, 'DWI', regulations) and commercially (alcoholic beverages). Blood- and breath-alcohol testing can be imposed on individuals operating private vehicles such as

In-Situ Hardening Hydroxyapatite-Based Scaffold for Bone Repair

July 7, 2005
Author(s)
Yu Zhang, Hockin D. Xu, Shozo Takagi, Laurence C. Chow
Musculoskeletal conditions are becoming a major health concern because of an aging population and sports- and traffic-related injuries. While sintered hydroxyapatite implants require machining, calcium phosphate cement (CPC) bone repair material is

A comprehensive evaluation of an outdoor vehicular test range

July 4, 2005
Author(s)
Robert T. Johnk, David R. Novotny, Chriss A. Grosvenor, Seturnino Canales, Janalee A. Graham, Louis L. Nagy, Doug Martin, Scott Yencer, Donald Hibbard, Tyrone L. Roach
This paper summarizes a joint industry/govenment effort to eveluate a large outdoor automotive antenna test range owned by a large automotive manufacturer.

A Review of Building Evacuation Models

July 1, 2005
Author(s)
Erica D. Kuligowski, Richard D. Peacock
Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-of-the-envelope (hand) calculation to assess life safety, and in others

A Review of Current Research Work on BGP Security

July 1, 2005
Author(s)
Kotikalapudi Sriram
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal

A Simulation Study of Repeatability and Bias in the CD-SEM

July 1, 2005
Author(s)
John S. Villarrubia, Andras Vladar, Michael T. Postek
Abstract: The ability of a critical dimension scanning electron microscope (CD-SEM) to resolve differences in the widths of two lines depends on the instrument?s measurement repeatability and any sample dependent biases. The dependence of repeatability and

Analysis of Deformation-Induced Surface Morphologies in Steel Sheet

July 1, 2005
Author(s)
Mark R. Stoudt, Joseph B. Hubbard
The surfaces of strained mild steel sheet specimens were examined with scanning laser confocal microscopy. Rigorous assessments were employed to establish the form of the roughness data. The small deviations from the ideal conditions observed in these

Application of Beamforming in Wireless Location Estimation

July 1, 2005
Author(s)
Kamran Sayrafian
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

Chaotic Scattering and Escape Times of Marginally Trapped Ultracold Neutrons

July 1, 2005
Author(s)
Kevin Coakley, J M. Doyle, S N. Dzhosyuk, L Yang, Paul R. Huffman
We compute classical trajectories of ultracold neutrons (UCNs) in a superconducting Ioffe-type magnetic trap using a symplectic integration method. We find that the computed escape time for a particular set of initial conditions (momentum and position)

Comments on IEEE 802.21, IEEE 802.21-05-0289, San Francisco, CA

July 1, 2005
Author(s)
Nicolas Montavont, Richard A. Rouil, Nada T. Golmie
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal

Data Exchange for Machine Shop Simulation

July 1, 2005
Author(s)
Yung-Tsun Lee, Yan Luo
Manufacturing simulation systems normally provide inter-faces for data import and export using proprietary formats. Dependent data interfaces limit simulation applications in the manufacturing industry. This paper describes a mecha-nism for transferring
