Author(s)
Lisa J. Fronczek, Bessmarie A. Young
The National Institute of Standards and Technology?s Manufacturing Engineering Laboratory (MEL)strengthens the U.S. economy and improves the quality of life by working with the U.S. manufacturing industry to develop and apply infrastructural technology

A Core Product Model for PLM with an Illustrative XML Implementation

March 1, 2005
Author(s)
Sebti Foufou, Steven J. Fenves, Conrad Bock, Sudarsan Rachuri, Ram D. Sriram
We propose a Core Product Model (CPM) for modeling product information suitable for supporting the information needs of Product Lifecycle Management (PLM) systems over the lifecycle of the product from the earliest ideation to manufacturing, operation and

Application Aspects of IPv6 Transition

March 1, 2005
Author(s)
M K. Shin
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

Assembled Designs for Estimation of Location, Dispersion, and Random Effects

March 1, 2005
Author(s)
A Aviles, B E. Ankenman, J C. Pinheiro
In many experimental settings, different types of factors affect the measured response. The factors that can be set independently of each other are called crossed factors. Nested factors cannot be set independently because the level of one factor takes on

Atomic Ordering Induced Energy Gap Reductions in GaAsSb Epilayers

March 1, 2005
Author(s)
B P. Gorman, A G. Norman, R Lukic-Zrnic, T D. Golding, Anthony G. Birdwell, Christopher Littler
A series of GaAs1-xSbx epilayers (0.51≪x≪0.71) grown by molecular-beam epitaxy on GaAs substrates with surface orientations of (001), (001) -8° toward (111)A, (001) -8° toward (111)B, (115)A, (115)B, (113)A, and (113)B were investigated using temperature

Band 3 Modifications in Plasmodium Falciparum-Infected AA and CC Erythrocytes Assayed by Autocorrelation Analysis Using Quantum Dots

March 1, 2005
Author(s)
F Tokumasu, R M. Fairhurst, G R. Ostera, N J. Brittain, Jeeseong C. Hwang, T E. Wellems, J A. Dvorak
The molecular stability of hemoglobin is critical for normal erythrocyte functions, including oxygen transport. Hemoglobin C (HbC) is a mutant hemoglobin that has increased oxidative susceptibility due to an amino acid substitution ( 6: Glu to Lys). The

Building Orientation and Wind Effects Estimation

March 1, 2005
Author(s)
P Hanzlik, S M. Diniz, A Grazini, Mircea Grigoriu, Emil Simiu
The methodology for estimating wind effects presented in this paper is based on the database-assisted design approach. It accounts for the effects of wind directionality, for the effects of the uncertainties in the parameters that determine wind effects

Characterization of Ordered Mesoporous Silica Films Using Small-Angle Neutron Scattering and X Ray Porosimetry

March 1, 2005
Author(s)
B D. Vogt, R A. Pai, V. J. Lee, R C. Hedden, Christopher L. Soles, Wen-Li Wu, Eric K. Lin, Barry J. Bauer, J J. Watkins
Ordered mesoporous silica films were synthesized using pre-organized block copolymer templates in supercritical carbon dioxide. Poly(ethylene oxide-block-propylene oxide-block-ethylene oxide), PEO-bPPO-b-PEO,films doped with p-toluenesulfonic acid (p-TSA)

Characterizing the Risks and Costs of BGP Insecurity/Security

March 1, 2005
Author(s)
Douglas Montgomery, Kotikalapudi Sriram, Oliver Borchert, Okhee Kim, D. Richard Kuhn
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

Coexistence Methodologies, IEEE 802.19-05-0012-00

March 1, 2005
Author(s)
Nada T. Golmie, S Shellhammer
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

Combinatorial Approach to Study Enzyme/Surface Interactions

March 1, 2005
Author(s)
K Loos, S L. Kennedy, Naomi Eidelman, Y Tai, M Zharnikov, Eric J. Amis, A Ulman, R A. Gross
A fast combinatorial approach to access information on the immobilization behavior and kinetics of enzymes on a variation of surfaces is presented. As a test system, Candida Antarctica Lipase B (CAL-B) was immobilized on a self-assembled monolayer (SAM)

Content-Level Conformance Testing: An Information Mapping Case Study

March 1, 2005
Author(s)
Boonserm Kulvatunyou, Nenad Ivezic, Albert T. Jones
Content-level conformance testing is a key to achieving interoper-able data exchange among applications deployed across collaborating, yet in-dependent enterprises. In this paper, we identify four types of content-level conformance tests to support

Crack-Tip Structure in Soda-Lime-Silicate Glass

March 1, 2005
