A Novel Multiaxial Wear Tester for Accelerated Testing of Materials

December 1, 1999
Author(s)
M C. Shen, Stephen M. Hsu, John A. Tesk, A Christou
A versatile wear tester has been designed and built. The initial study showed that that with this tester, tes procedures can be developed to achieve clinically relevant simulations in a short time. With the continuously monitored force traces, this tester

Absolute Intensities for the O 2 1.27 ym Continuum Absorption

December 1, 1999
Author(s)
B Mate, C Lugez, Gerald T. Fraser, Walter J. Lafferty
Collision-induced absorption coefficients for the 1.27 υm band of O 2 have been measured at a resolution of 0.5 cm -1 and an optical pathlength of L = 84 m using a Fourier-transform spectrometer and 2 m long White-type multipass absorption cell. Spectra

Alignment and Orientation Effects in Sr Energy Pooling

December 1, 1999
Author(s)
Harold V. Parks, S R. Leone
Alignment and orientation effects in the energy pooling process, Sr(5s5p 3P 1) + Sr(5s5p 3P 1)-> Sr(5s5p 1P 1) + Sr(5s 2 1S o), are studied in a single atomic beam. The Sr atoms are prepared in an aligned initial state with a polarized laser, and alignment

Application of Microcalorimeter EDS X-Ray Detectors to Particle Analysis

December 1, 1999
Author(s)
Alain C. Diebold, David A. Wollman, Gene C. Hilton, Kent D. Irwin, John M. Martinis, B. H. Liu
New microcalorimeter x-ray detector technology will revolutionize materials characterization. It is expected that the microcalorimeter EDS (energy dispersive spectrometer) will replace traditional lithium-drifted silicon semiconductor EDS due to its

Calibrations of Colorimeters for Display Measurements: Some Commercial Colorimeters Have Uncertainties in Display-Color Measurements That Are Too Large for Many Commercial, Industrial and Military Applications - But New NIST-Developed Calibration Proc...

December 1, 1999
Author(s)
Steven W. Brown, Yuqin Zong, Yoshihiro Ohno
Commercial color measuring instruments (colorimeters and spectroradiometers) are currently used in a number of product development and control environments, as well as for product acceptance testing and a variety of other applications. In many cases, the
