On-Wafer Measurement at Millimeter Wave Frequencies

June 1, 1996
Author(s)
Dylan F. Williams, J. M. Belquin, G. Dambrine, R. Fenton
We investigate millimeter wave on-wafer calibration and measurement in coplanar waveguide and demonstrate the applicability of the multiline thru-reflect-line calibration and good measurement repeatability between laboratories. We also investigate

Progress Toward an AC Josephson Voltage Standard

June 1, 1996
Author(s)
Clark A. Hamilton, Charles J. Burroughs, Samuel P. Benz
Progress toward a Josephson voltage standrd for fast dc measurements and ac waveform synthesis is described, including a version with SNS junctions operated at 11 GHz. A bias control circuit that achieves millampere drive capability, transient suppression

Sources of Strain-Measurement Error in Flag-Based Extensometry

June 1, 1996
Author(s)
William E. Luecke, J French
This paper examines the sources of error in strain measurement using flag-based extensometry that uses either scanning laser or electrooptical extensometers, These errors fall into two groups: errors in measuring the true gauge length of the specimen

Validation of Standards Interfaces for Machine Control

May 27, 1996
Author(s)
Frederick M. Proctor, John L. Michaloski, William P. Shackleford, Sandor S. Szabo
Open architecture controllers offer a multitude of benefits to users of machine tools, robots, and coordinate measuring machines, ultimately reducing the life-cycle costs of installing, operating, and maintaining manufacturing equipment. Aside from those

Polymer Combustion and New Flame Retardants

May 20, 1996
Author(s)
Takashi Kashiwagi, Anthony P. Hamins, Kenneth D. Steckler, Jeffrey W. Gilman
The combustion of polymers is a complex coupled process characterized by energy feedback from a flame to the polymer surface and subsequent gasification of the polymer to generate combustible degradation products. Energy feedback characteristics for two

New Silyl Derivatives for the Determination of Alcohols by GC/MS

May 12, 1996
Author(s)
Vladimir G. Zaikin, Michael Y. Shmatko, Anzor I. Mikaia
1-Methyl-1-silacyclobutyl, 1-Methyl-1-silacyclopentyl, pentamethyldisilaethyl and pentamethyl-1,3- disilapropyl derivatives for alcohols are obtained, and characteristic peaks in their mass spectra are revealed. The use of specific silyl derivatives for

Ab Initio Calculations and Kinetic Modeling of Halon and Halon Replacements

May 7, 1996
Author(s)
H. L. Paige, R J. Berry, M Schwartz, P Marshall, D R. Burgess, Marc R. Nyden
The mode of action of the chemical-acting flame suppression agents such as the halons is generally, though not universally, accepted. The details of the several reactions involved in chemical suppression have been studied by many groups using experimental

SCATMECH: Polarized Light Scattering C++ Class Library (Version 3.00)

May 6, 1996
Author(s)
Thomas A. Germer
A C++ object class library has been developed to distribute bidirectional reflectance distribution function (BRDF) models for light scattering from surfaces. Emphasis has been given to those models which are physically-based and which predict the
