Microstuctural Characterization of Hardened Steel by Nondestructive Methods

July 1, 1997
Author(s)
P T. Purtscher, B Igarashi, Donna C. Hurley, K W. Hollman
This paper describes the application of a variety of methods to the nondesctructive characterization (NDC) of microstructure in hardened steels. The measurements include ultrasonic velocity, nonlinear ultrasonics, resonant ultrasonic spectroscopy (RUS)

Practical Aspects of Touch Trigger Probe Error Compensation

July 1, 1997
Author(s)
William T. Estler, Steven D. Phillips, Bruce R. Borchardt, Ted Hopp, M Levenson, K Eberhardt, Marjorie A. McClain
We present extensions of our prior work in modeling and correcting for pretravel variation errors in kinematic seat touch-trigger coordinate measuring machine (CMM) probes with straight styli. A simple correction term is shown to account for a range of

Statistical Measure for the Sharpness of the SEM Image

July 1, 1997
Author(s)
Nien F. Zhang, Michael T. Postek, Robert D. Larrabee
Fully automated or semi-automated scanning electron microscopes (SEM) are now commonly used in semiconductor production and other forms of manufacturing. Testing and proving that the instrument is performing at a satisfactory level of sharpness is an

Tcl/Tk-based Agents for Mail and News Notification or A Tale of Two Biffs

July 1, 1997
Author(s)
Don E. Libes
Two agent implementations are described - one for mail notification and one for news notification. Both agents are implemented using Tcl. This paper provides a brief history and perspective of similar agents. Included are experiences using Tcl as an agent

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
