High Throughput Methods for Materials R&D: A Growing Effort at NIST

April 1, 2002
Author(s)
Leonid A. Bendersky, J D. Hewes
The U.S. private sector has indicated that the National Institute of Standards and Technology has a role to play in facilitating the implementation of high throughput experimentation, for example using combinatorial methods. The Advanced Technology Program

Improved IDDQ Testing With Empirical Linear Prediction

April 1, 2002
Author(s)
David I. Bergman, Hans Engler
A new linear prediction method that improves IDDQ test effectiveness is described. The method uses statistical pre-processing of exhaustive measurements on training devices to extract principal patterns in the device IDDQ behavior and to generate a

Influence of Processing Rate and Formulation on the Interface Strength of Vinyl Ester/E-Glass Composites

April 1, 2002
Author(s)
Walter G. McDonough, Joy Dunkers, Gale A. Holmes, E Feresenbet, Y H. Kim, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The single fiber fragmentation test was used to investigate the effect of gelation time on interfacial shear properties of fast reacting resin systems. We developed a processing system capable of producing single fiber fragmentation samples with gelation

It's Bound to Be Right

April 1, 2002
Author(s)
Isabel M. Beichl, F Sullivan
This is a tutorial article on a Monte Carlo method for eliminating double counting in massive data sets. It has also been used to classify images.

Measurement of the Linewidth of Electrical Test-Structure Reference Features by Automated Phase-Contrast Image Analysis

April 1, 2002
Author(s)
B A. am Ende, Michael W. Cresswell, Richard A. Allen, T J. Headley, William F. Guthrie, Loren W. Linholm, H Bogardus, Christine E. Murabito
NIST, Sandia National Laboratories, and International SEMATECH are developing a new type of linewidth standard for calibrating Critical Dimension (CD) metrology instruments for lithographic process control. The standard reference feature is the bridge of

Momentum Dependence of Fluorine K-Edge Core Exciton in LiF

April 1, 2002
Author(s)
K Hamalainen, S Galambosi, J A. Soininen, Eric L. Shirley, A Shukla, J P. Rueff
Non-resonant inelastic x-ray scattering spectra have been measured with an energy loss close to the fluorine K-edge of lithium fluoride. The extracted dynamic structure factor is well reproduced by an ab initio computational scheme that takes the electron

NIST Metric Pyramid

April 1, 2002
Author(s)
J B. McCracken
Paper cut-out pyramid, 10 cm x 10 cm x 10 cm, listing metric conversion information on each face covering units of length, mass or weight, area or surface, energy, volume and temperature. The bottom face lists metric symbols.

Non-Equilibrium Pattern Formation in the Crystallization of Polymer Blend Films

April 1, 2002
Author(s)
V Ferreiro, Jack F. Douglas, James A. Warren, Alamgir Karim
The crystallization of polymeric and metallic materials normally occurs under conditions far from equilibrium. The morphologies formed reflect a competition between order associated with the symmetries of the equilibrium crystal geometry and disorder

On Repeated Adiabatic Shear Band Formation During High-Speed Machining

April 1, 2002
Author(s)
Timothy J. Burns, Matthew A. Davies
We compare the repeated adiabatic shear band formation that takes place at sufficient large cutting speeds in a number of materials during high speed machining operations with the more well known formation of a single shear band that often takes place at

Orbital-Resolved Soft X-Ray Spectroscopy in NaV 2 O 5

April 1, 2002
Author(s)
G P. Zhang, G T. Woods, Eric L. Shirley, T A. Callcott, L Lin, B. C. Sales, D Mandrus, G S. Chang, J He
We demonstrate that angle-resolved soft x-ray spectroscopy can resolve absorption by inequivalent oxygen sites and by different orbitals belonging to the same site. By rotating the polarization direction, we see a dramatic change in the absorption spectra

Overview of the TREC 2001 Question Answering Track

April 1, 2002
Author(s)
Ellen M. Voorhees
The TREC question answering track is an effort to bring the benefits of large-scale evaluation to bear on the question answering problem. In its third year, the track continued to focus on retrieving small snippets of text that contain an answer to a

Phase Stabilization of Ultrashort Optical Pulses

April 1, 2002
Author(s)
Steven T. Cundiff
New methods have recently been developed to measure the carrier-envelope phase evolution of ultrashort optical pulses. These methods utilize a powerful combination of time-domain and frequency-domain techniques. The resulting ability to stabilize the

Probing Potential Surfaces for Hydrogen Bonding: Near-Infrared Combination Band Spectroscopy of Van Der Waals Stretch (N 4 ) and Geared Bend (N 5 ) Vibrations in (HCl) 2

April 1, 2002
Author(s)
M Farnik, S Davis, M D. Schuder, David Nesbitt
High resolution infrared spectra of the two low frequency intermolecular modes - van der Waals stretch (Ņ 4) and geared bend (Ņ 4) and geared bend (Ņ 5) of (HCI) 2 - have been characterized in HCI-stretch excited states using a slit jet spectrometer. In a

Process Sensitivity of GMAW: Aluminum vs. Steel

April 1, 2002
Author(s)
Timothy P. Quinn
A heat-transfer model of the melting electrode in gas metal are welding (GMAW) was used to compare the relative sensitivity of the process when welding with aluminum electrodes compared to that of steel electrodes. The aluminum model was verified with
