Writing a Tcl Extension in Only Seven Years

July 1, 1997
Author(s)
Don E. Libes
Tcl is a command language library for embedding into other applications. It is often touted as the best language for this purpose and it is only natural that this claim should be investigated. This paper assists in that investigation by describing

4-D/RCS Version 1.0: A Reference Model Architecture for Demo III

June 27, 1997
Author(s)
James S. Albus
4-D/RCS is a reference model architecture that provides a theoretical foundation for designing, engineering, integrating, and testing intelligent controllers for unmanned ground vehicle systems. 4-D/RCS integrates the NIST (National Institute of Standards

What Does it Take to Make Good Things Happen?

June 27, 1997
Author(s)
J E. Snell
The theme of this symposium is fire risk and hazard assessment research application. We tend to focus on the tools which in themselves are means to some end, what are the ends we are trying to address? A central question regarding this topic must be who

Embedded multiconductor transmission line characterization

June 8, 1997
Author(s)
Dylan F. Williams
This paper presents a measurement method that characterizes lossy printed multiconductor transmission lies embedded in transitions, connectors, or packages with significant electrical parasitics. We test the method on a pair of lossy coupled asymmetric

Surveying Through Solid Walls

June 8, 1997
Author(s)
William C. Stone
A good metrology system in the automated environment must (1) measure the three dimensional position and attitude of any component to a reasonable degree of accuracy; (2) acquire these data fairly rapidly; and (3) be capable of making reliable measurements

980 nm-pumped Er- and Er/Yb-doped waveguide lasers in LiNbO 3

June 1, 1997
Author(s)
J. Amin, J. A. Aust, D. L. Veasey, Norman Sanford
We demonstrate a 980 nm-pumped Er- and the first Er/Yb-doped waveguide laser in Ti:LiNbO 3. The devices were fabricated on x-cut LiNbO 3, with the guides parallel to the z-axis. This choice of waveguide orientation results in a reduced susceptibility to

Advanced Fire Safe Materials for Aircraft Interiors

June 1, 1997
Author(s)
R E. Lyon
Phenomenological equations for solid material burning in combination with pyrolysis kinetics and uncoupled transient heat conduction provide relationships between material properties and the fire response of polymeric solids. The predicted scaling of

Carbon Monoxide Formation Algorithm (NISTIR 6030)

June 1, 1997
Author(s)
William M. Pitts
This paper discusses an engineering approach for estimating the generation rate of carbon monoxide (CO) within a room containing a fire. The algorithm incorporates four CO formation mechanisms which have been identified in past investigations.
