Impedance Mismatch Effects on Propagation Constant Measurements

October 1, 1996
Author(s)
Donald C. DeGroot, Dave K. Walker, Roger Marks
By measuring propagation constants of coplanar waveguide transmission lines, we show the significant systematic errors of common measurement techniques when the characteristic impedance of the lines does not match the reference impedance of the instrument.

International Intercomparison of Horn Gain at X-Band

October 1, 1996
Author(s)
Carl F. Stubenrauch, Allen C. Newell, Andrew G. Repjar, Katherine MacReynolds, Douglas T. Tamura, F. Holmlarsen, J. Lemancyzyk, R. Behe, G. Portier, J. C. Zehren, H. Hollman, J. D. Hunter, David Gentle, Jan P. deVreede

NIIIP Reference Architecture - Glossary

October 1, 1996
Author(s)
Peter O. Denno
The National Industrial Information Infrastructure Protocols (NIIIP) Consortium is a collection of companies, government and academic institutions developing protocols and a reference architecture to enable virtual enterprises. This paper, a glossary, is

Quantum-state-resolved 2-level femtosecond rotational coherence spectroscopy: Determination of rotational constants at medium and high J in Li 2 , a simple diatomic system

October 1, 1996
Author(s)
R M. Williams, J M. Papanikolas, J , . Rathje, S R. Leone
Rotational wave packet recurrences originating form a single 2-level coherent rotational superposition are observed in the E( 1Σ + g) state of Li 2. The rotational wave packet is created by ultrafast laser excitation from a specific ro-vibrational level in

Stylus-Laser Surface Calibration System

October 1, 1996
Author(s)
Theodore V. Vorburger, Jun-Feng Song, T Giauque, Thomas Brian Renegar, Eric P. Whitenton, M Croarkin
A stylus-laser surface calibration system was developed to calibrate the NIST sinusoidal roughness Standard Reference Materials (SRM) 2071-2075. Step height standards are used to calibrate the stylus instrument in the vertical direction, and a laser

IEEE-P1451.2 Smart Transducer Interface Module

September 11, 1996
Author(s)
Stan Woods, David Rasmussen, Michael Mattes, Kang B. Lee, Norm Lecomte, John Houldsworth, Fernando Gen_kuong, Micahel Geipel, Edwin El-kareh, Steven Cranmer, S Chen, Januz Bryzek
This paper provides a technical overview of the smart transducer interface module (STIM), the key element of the proposed IEEE-P1451.2 Draft Standard for Transducer to Microprocessor Communication Protocols and Transducer Electronic Data Sheets (TEDS)

The Engineering of Mind

September 9, 1996
Author(s)
James S. Albus
While the mind remains a mysterious and inaccessible phenomenon, many of the components of mind, such as perception, behavior generation, knowledge representation, value judgment, reason, intention, emotion, memory, imagination, recognition, learning

A Methodology for the Reduction of Imprecision in the Engineering Process

September 1, 1996
Author(s)
Ronald Giachetti, R Young, A Roggatz, W Eversheim, G Perrone
Engineering design is characterized by a high level of imprecision, vague parameters, and ill-defined relationships. In design, imprecision reduction must occur to arrive at a final product specification. Few design systems exist for adequately
