Calculating Characteristics of Non-collinear Phase-Matching in Uniaxial and Biaxial Crystals

April 1, 2000
Author(s)
N Boeuf, D A. Branning, I Chaperot, E Dauler, S Guerin, G Jaeger, Andreas Muller, Alan L. Migdall
A method of calculating the characteristics of phase-matching in both uniaxial and biaxial crystals is presented. Although significant work has been done to characterize the collinear case of phase-matching and to present many of its applications, the non

Calibrated Thermal Microscopy of the Tool-Chip Interface in Machining

April 1, 2000
Author(s)
Michael Kennedy, Matthew A. Davies, Howard W. Yoon, Timothy J. Burns
A critical parameter in predicting tool wear during machining and in accurate computer simulations of machining is the spatially-resolved temperature at the tool-chip interface. We describe the development and the calibration of a nearly diffraction

Calibration of Lightpipe Radiation Thermometers in a RTP Tool at 1000 C

April 1, 2000
Author(s)
Kenneth G. Kreider, D P. DeWitt, Christopher W. Meyer, Vincent P. Scheuerman
We are developing an instrumented calibration wafer for radiometric temperature measurements in rapid thermal processing (RTP) that uses Pt/Pd wire and noble metal thin-film thermocouples that are welded to thin-film pads of Pt. The Pt/Pd wire

Ceramic Manufacturing Program World Wide Web Site

April 1, 2000
Author(s)
Vincent A. Hackley
The Ceramic Manufacturing Program (CMP) World Wide Web Site contains general information on CMP research projects, personnel, facilities and industrial consortia. An overview of the program mission and goals is also provided, along with lists of

CODATA Recommended Values of the Fundamental Constants: 1998

April 1, 2000
Author(s)
Peter J. Mohr, Barry N. Taylor
This paper gives the 1998 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. Further, it describes in detail

Coherent Control of Precessional Dynamics in Thin Film Permalloy

April 1, 2000
Author(s)
T. M. Crawford, Pavel Kabos, Thomas J. Silva
We demonstrate a method of eliminating overshoot and ringing in magnetizaiton dynamics when the system bandwidth includes the intrinsic ferromagnetic resonance (FMR). The method employsstaggered step excitation for the cancellation of FMR oscillations

Colloids Reinforce Glass Theory

April 1, 2000
Author(s)
S C. Glotzer
Nobel laureate Phil Anderson wrote in Science in 1995 that the glass transition remains the deepest and most important unsolved problem in solid state physics. Why all the mystery surrounding the seemingly simple solidification of a liquid into a

Common Industry Format for Usability Test Reports

April 1, 2000
Author(s)
Jean C. Scholtz
This paper is a proposal for conducting a Special Interest Group (SIG) at the CHI2000 Conference. The focus of the meeting will be the use of the Common Industry Format (CIF) developed by the Industry Usability Reporting (IUSR) project, a group managed by

Compositional Analysis of NIST Reference Material Clinker 8486

April 1, 2000
Author(s)
Paul E. Stutzman, Germain Lespinasse, Stefan D. Leigh
Certification of the phase compositions of the NIST Reference Clinkers often is based upon more than one independent method. The current certificate values were established using an optical microscope examination, and additional microscope data taken from

Contribution of Evanescent Waves to the Far-Field: the Atomic Point of View

April 1, 2000
Author(s)
A Rahmani, Garnett W. Bryant
Evanescent modes of the electromagnetic field are seldom invoked in conventional far-field optics, as their contribution far from the source (say a few wavelengths) is negligible. Contradicting this fact, in recent theoretical works, based on a particular

Controller Driven VRML Animation of the NIST Robotic Welding Cell

April 1, 2000
Author(s)
Keith A. Stouffer
Virtual objects in a web-based environment can be interfaced to and controlled by external real world controllers. A Virtual Reality Modeling Language (VRML) welding cell was created that models a robotic arc welding cell (the Automated Welding
