Sapphire Statistical Characterization and Risk Reduction Program

September 1, 2001
Author(s)
D R. McClure, R W. Cayse, David R. Black, S M. Goodrich, K Peter, D Lagerloef, D C. Harris, D McCullum, D H. Platus, C E. Patty, Robert S. Polvani
The Sapphire Statistical Characterization and Risk Reduction Program tested 1400 4-point flexure bars with different crystal orientations at different temperatures to establish a mechanical strength database for engineering design. Sapphire coupons were

Simulation-Based Shop Floor Control: Formal Model, Model Generation,

September 1, 2001
Author(s)
Albert T. Jones, Y J. Son, R A. Wysk
The high cost of control software development and maintenance has been recognized as a significant problem inhibiting CIM solutions. In this paper, a structure and architecture for the rapid realization of a simulation-based real-time shop floor control

Sorptivity-Based Service Life Predictions for Concrete Pavements

September 1, 2001
Author(s)
Dale P. Bentz, M A. Ehlen, Chiara F. Ferraris, Edward J. Garboczi
The degradation of concrete pavements is often controlled by the transport of a deleterious species (chloride or sulfate ions, or water in the case of freeze/thaw) into the concrete. With this in mind, a three-year research project, funded by the Federal

Speaker Recognition in a Multi-Speaker Environment

September 1, 2001
Author(s)
Alvin F. Martin, Mark A. Przybocki
We discuss the multi-speaker tasks of detection, tracking, and segmentation of speakers as included in recent NIST Speaker Recognition Evaluations. We consider how performance for the two-speaker detection task is related to that for the corresponding one

Standards for Collaborative Product Development

September 1, 2001
Author(s)
Ram D. Sriram
We are currently witnessing the emergence of an Internet-based engineering marketplace, where engineers, designers, and manufacturers from small and large companies are collaborating through the Internet to participate in RFQs (requests for quotes), create

Tensile Properties of Free-Standing Aluminum Thin Films

September 1, 2001
Author(s)
David T. Read, Yi-Wen Cheng, R R. Keller, Joseph D. McColskey
Tensile properties of electron-beam-deposited free-standing aluminum thin films were measured. High ς y and UTS were observed, mainly due to fine grain sizes, consistent with values reported in the literature. The observed Young's modulus, as measured by

The Next Step- IEEE 1451 Smart Sensor Networks

September 1, 2001
Author(s)
M R. Moore, Kang B. Lee, SM F. Smith
IEEE 1451 is a family of standards that links sensors to users, similar to the way that IEEE 802 (Ethernet) provides connectivity for information systems. Currently, all working groups under the IEEE 1451 umbrella provide standard interfaces for sensors on

The Next Step- IEEE 1451 Smart Sensor Networks Go Wireless

The Performance of a Nanocrystalline Tungsten Composite in Ballistic Impacts

September 1, 2001
Author(s)
L S. Magness, L Kesckes, Frank S. Biancaniello, Stephen D. Ridder, M Chung, D Kapoor
A novel tungsten heavy alloy with a nanocrystalline microstructure was produced. Tungsten powders were ball milled in a controlled atmosphere environment, with rapidly solidified powders of a binder alloy known to exhibit a stress-induced martensitic

The Stability of Nb/Nb 5 Si 3 Microlaminates at High Temperatures

September 1, 2001
Author(s)
D van Heerden, A J. Gavens, P R. Subramanian, Timothy J. Foecke, Timothy P. Weihs
The chemical, phase and microstructural stability of Nb/Nb 5Si 3 microlaminates was investigated at temperatures ranging from 1200 C to 1600 C. The microlamintes were vapor deposited at room temperature and subsequently annealed at 1200 C to crystallize
