Forum Report: Permissive Metric Only Labeling

October 16, 2008
Author(s)
Kenneth S. Butcher
Report on the Forum on Metric-only Labeling held on November 7, 2002, in Washington, DC. The National Institute of Standards and Technology and the National Conference on Weights and Measures sponsored this forum to initiate a joint effort to eliminate

Fourier Instrumentation for Radiation Thermometry

October 16, 2008
Author(s)
F J. Dunmore
A miniature Fourier transform spectrometer (MFTS) has been tested as a device for remotely measuring the temperature of a high-stability/emissivity blackbody. The commercially manufactured device is based on the novel design of a polarizing Wollaston prism

Fractographic Failure Analysis of a Broken Tooth Following Larnygoscopy

October 16, 2008
Author(s)
Janet Quinn, L W. Schultheis
ckground: A tooth broken subsequent to laryngoscopy was fractographically analyzed. The science of fractography involves examination of fracture surfaces to determine information such as failure causes, crack progressions, and stress configurations.Case

Fracture Modes in Brittle Coatings With Large Interlayer Modulus Mismatch

October 16, 2008
Author(s)
Herzl Chai, Brian R. Lawn, S Wuttiphan
Fracture modes in a model glass/polymer coating/substrate system indented with hard spheres are investigated. The large modulus mismatch between the glass and polymer results in distinctive transverse fracture modes in the brittle coating: exaggerated

Fracture of Silicate Glasses: Ductile or Brittle?

October 16, 2008
Author(s)
J -. Guin, Sheldon M. Wiederhorn
Atomic force microscopy is used to investigate the possibility of crack tip cavitation during crack growth in silicate glasses. Matching areas on both surfaces of a crack were mapped and then compared for soda-lime silicate glass and for silica glass. For

From Stable Lasers to Optical-Frequency Clocks

October 16, 2008
Author(s)
John L. Hall, Jun Ye, L -. Ma, J L. Peng, M Notcutt, J D. Jost, A Marian
This is a report on behalf of the World Tema of Stable Laser and Optical Frequency Measurement Enthusiasts, even if most detailed illustrations draw mainly from our work at JILA. Specifically we trace some of the key ideas that have led from the first

FY 1998 Materials Reliability Division Annual Report

October 16, 2008
Author(s)
H I. McHenry
The technical activities of the Materials Reliability Division during Fiscal year 1998 are summarized. The Division has eighteen research projects in five program areas: Metals Processing (3), Ultrasonic Characterization of Materials (9), Electronic

FY 2001 Programs and Accomplishments - Materials for Microelectronics

October 16, 2008
Author(s)
Frank W. Gayle
Today's U.S. microelectronics and supporting infrastructure industries are in fierce international competition to design and produce new smaller, lighter, faster, more functional, and more reliable electronics products more quickly and economically than

Gas-Gas Equilibria - From Van der Waals to Ulrich Franck

October 16, 2008
Author(s)
Johanna Levelt Sengers
The experimental work of Ulrich Franck and his collaborators on phase separation in binary aqueous mixtures of gases at high pressures and temperatures is summarized and placed against the background of the school of Van der Waals, Van Laar and Kamerlingh

Glass Pocket Evolution in Vitreous Bonded Sapphire

October 16, 2008
Author(s)
Jong S. Lee, M K. Kang, Sheldon M. Wiederhorn, B Hockey, J Blendell
This paper discusses the evolution of glass filled pockets formed by the growth of sapphire through polycrystalline aluminum oxide bonded by anorthite glass. During growth, excess glass is entrapped within the sapphire as channels, which, upon annealing

Globalization of Technical and Safety Standards

October 16, 2008
Author(s)
H V. Oppermann
Standards and conformity assessment practices can have a major impact on competitiveness and ease of access to the international market. Even if companies are not currently exporting products, they are likely to experience the impact of standards on their

Guided Data Capture (GDC) Software

October 16, 2008
Author(s)
Vladimir Diky, Robert D. Chirico, R C. Wilhoit, Qian Dong, Michael D. Frenkel
The program provides software tools to ease capture (compilation) of experimental thermodynamic and transport property data from the literature for pure compounds, binary and ternary mixtures, and chemical reactions (including change-of-state and

He 4 Thermophysical Properties: New ab initio Calculations

October 16, 2008
Author(s)
John J. Hurly, J B. Mehl
Since 2000, atomic physicists have reduced the uncertainty of the helium-helium ab initio potential,for example, from approximately 0.6% to 0.1% at 4 bohr and from 0.8% to 0.1% at 5.6 bohr.These results led us to: (1) construct a new interatomic potential

High Order Shape Functions for Finite Element Analysis

October 16, 2008
Author(s)
Frederick R. Phelan Jr.
A formalism for high-order shape functions used in finite element analysis is developed. The formalism allows the shape functions to be conveniently expressed in terms of their polynomial order p, and their derivative level k. The formalism is verified by
