Modeling Spatial Reasoning Systems With Shape Algebras and Formal Logic

June 1, 1996
Author(s)
Scott Chase
The combination of the paradigms of shape algebras and predicate logic representations,used in a new method for describing designs, is presented. First order predicate logicprovides a natural, intuitive way of representing shapes and spatial relations

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
