A Tool to Improve Efficiency in Large Scale Manufacturing

September 25, 2002
Author(s)
Roger V. Bostelman, William P. Shackleford, Frederick M. Proctor, James S. Albus, Alan M. Lytle
NIST is working directly with industry to improve repair and conversion operations of ships in dry dock. Similarly, this work allows transfer of technology to construction and other industries requiring worker-access to large, external surfaces with

Advancements in Tele-Robotic Pipelaying

September 23, 2002
Author(s)
L E. Bernold, B Li
The labor intensive construction industry has a very high accident rate. One of the key reasons for this is the exposure of workers to a hazardous environment such as heights, confined narrow spaces, and exposure to health threatening fumes, dust, and

Bimodal Size Distribution of Self-Assembled InGaAs Quantum Dots

September 23, 2002
Author(s)
Solveig Anders, C. S. Kim, Benjamin D. Klein, Mark W. Keller, Richard Mirin
We investigate energy level quantization in self-assembled InGaAs quantum dots that are embedded In a GaAs matrix. We use capacitance and photoluminescence spectroscopy to analyze the evolution of the energy levels with varying amounts of deposited InGaAs

Knowledge Engineering for Real Time Intelligent Control

September 18, 2002
Author(s)
John Evans, Elena R. Messina, James S. Albus
The key to real-time intelligent control lies in the knowledge models that the system contains. Three main classes of knowledge are identified: parametric, geometric/iconic, and symbolic. Each of these classes provides unique perspectives and advantages
