In-Flight Suppressant Deployment Temperatures

February 28, 2006
Author(s)
Donald Bein
This report describes review of DoD military fixed-wing and rotary aircraft fire mishap/incident data applicable to assess temperatures at which aircraft fire suppressants have been deployed in engine nacelle and APU compartment fires. Another model is

Using NTP: Introduction and Recommended Practices

February 28, 2006
Author(s)
YaShian Li-Baboud
With future e-Manufacturing applications requiring precisely synchronized time for merging data from heterogeneous sources, it is necessary to understand the factors causing synchronization degradation in semiconductor factory distributed systems, and how

Improved Thermal Detector Coatings for Laser Radiometry at NIST

February 27, 2006
Author(s)
John H. Lehman
Nearly all of the radiometric standards for laser power and energy measurements at NIST and elsewhere in the world are based on thermal detectors. These detectors usually rely on a thermal absorber coating to enhance the detector responsivity. Ideally the

The Next Generation of Laser Radiometry at NIST

February 27, 2006
Author(s)
John H. Lehman, Christopher L. Cromer, Marla L. Dowell
High accuracy laser radiometry is on the verge of significant improvements just as new laser technologies are evolving. Our present tasks are directed toward anticipating and meeting the measurement needs in two areas; higher power and shorter wavelengths

Characterizing reliability of multilayer PZT actuators

February 26, 2006
Author(s)
Stephanie A. Hooker
Many new applications are emerging for piezoelectric ceramics including adaptive structures, active-flow-control devices, and vibration and noise suppression systems. Additionally, there are opportunities to use these devices in the biomedical field for

Method and Apparatus for Precision In-Line Sampling of Distillate

February 26, 2006
Author(s)
Thomas J. Bruno
In this short note we present a method and a simple apparatus for use with simple, fractional and steam distillation operations in which the operator requires a precise measurement of instantaneous distillate composition as the distillation proceeds. There

Guide for Developing Security Plans for Information Technology Systems

February 24, 2006
Author(s)
Marianne M. Swanson, Joan Hash, Pauline Bowen
The objective of system security planning is to improve protection of information system resources. All federal systems have some level of sensitivity and require protection as part of good management practice. The protection of a system must be documented

Cross-Display-Technology Video Motion Measurement Tools

February 23, 2006
Author(s)
John W. Roberts, Edward A. Fanning, Hassan A. Sahibzada
High performance video places severe demands on playback system and display device resources. Motion playback errors such as irregular motion playback and image breakup are common, making accurate measurement of motion critically important for device

Estimation of the Interfacial Adhesion Strength in Compositional Libraries of Epoxy Films

February 22, 2006
Author(s)
Jae Hyun Kim, Martin Y. Chiang, D Kawaguchi, Gareth Royston, Christopher M. Stafford
At the NIST Combinatorial Methods Center (NCMC), we have designed, developed, and demonstrated a combinatorial approach to the edge delamination test to char-acterize the adhesion of thin polymer films. This test is based on fracture of a film/substrate

Universal Gradient Substrates for Click Biofunctionalization

February 22, 2006
Author(s)
Nathan D. Gallant, Kristopher Lavery, Eric J. Amis, Matthew Becker
In order to facilitate research on biomimetic and tissue engineered medical products we have developed a novel and versatile method for fabricating continuously variable concentration gradients of surface conjugated biomolecules. This technology utilizes

Comment on the paper Metrologia 42 49-57 (2005) by K. Szymaniec et al,

February 21, 2006
Author(s)
Steven R. Jefferts, F Levi
A recent evaluation of the accuracy of National Physical Laboratory (NPL) primary frequency standard NPL CsF1 gives an overall frequency uncertainty of δŅ/Ņ 0 = 1 × 10 -15. This stated uncertainty includes a correction of a frequency bias of δŅ/Ņ 0 = 8 ×

Spin Transfer Torque for Continuously Variable Magnetization

February 21, 2006
Author(s)
J Xiao, A Zangwill, Mark D. Stiles
We report quantum and semi-classical calculations of spin current and spin-transfer torque in a free-electron Stoner model for systems where the magnetization varies continuously in one dimension. Analytic results are obtained for an infinite spin spiral

An Empirical Analysis of IPv6 Transition Mechanism

February 20, 2006
Author(s)
M K. Shin, Darrin J. Santay, Douglas Montgomery
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

Nonlinearity of high-power optical fiber power meters at 1480 nm

February 20, 2006
Author(s)
Igor Vayshenker, Shao Yang, Ralph Swafford
We describe a calibration system that measures the nonlinearity of optical fiber power meters (OFPMs) at a maximum power of 0.6 W and a minimum power of 0.2 mW at 1480 nm. The system is based on the triplet superposition method. This system measures the

Simple Spectral Stray Light Correction Method for Array Spectroradiometers

February 20, 2006
Author(s)
Yuqin Zong, Steven W. Brown, Bettye C. Johnson, Keith R. Lykke, Yoshihiro Ohno
In many applications, the measurement accuracy of spectroradiometers, particularly instruments with a single dispersive element, is limited by the presence of stray radiation within the instrument. A simple, practical method has been developed to correct a
