Real-Time GPS and Non-Line-of-Sight Metrology

May 1, 1996
Author(s)
William C. Stone
I would like to pick up where Eric left off and describe the results of research which is currently underway at NIST in the field of construction metrology. Earlier I indicated that there were many technological steps along the way to implementing the real

SEM Performance Evaluation Using the Sharpness Criterion

May 1, 1996
Author(s)
Michael T. Postek, Andras Vladar
Fully automated or semi-automated scanning electron microscopes (SEM) are now commonly used in semiconductor production and other forms of manufacturing. The industry requires that an automated instrument must be routinely capable of 5 nm resolution (or

Nanostructure Fabrication via Laser-Focused Atomic Deposition

April 15, 1996
Author(s)
Robert Celotta, R Gupta, R E. Scholten, Jabez McClelland
Nanostructured materials and devices will play an important role in a variety of future technologies, including magnetics. We describe a method for nanostructure fabrication based on the use of laser light to focus neutral atoms. The method uses neither a

An Architecture and a Methodology for Intelligent Control

April 1, 1996
Author(s)
Hui-Min Huang
We outline a multiple dimensional reference model architecture and a methodology for representing and developing intelligent systems. The reference model architecture features multiple dimensions enabling modeling the multiple aspects of complex systems

GPS Aided Retrotraverse For Unmanned Ground Vehicles

April 1, 1996
Author(s)
Karl Murphy, Steven Legowik
A computer controlled HMMWV automatically retraces a previously recorded path using navigation data, a process we have termed retrotraverse. A Kalman filter combines the output of two navigation systems, an inertial dead reckoning system and a differential

Inhibition of Premixed Methane-Air Flames by Fluoromethanes

April 1, 1996
Author(s)
Gregory T. Linteris, L Truett
This paper presents the first calculations and measurements of the burning velocity of premixed hydrocarbon flames inhibited by the three one-carbon fluorinated species CH2F2, CF3H, and CF4. The chemistry of these agents is expected to be similar to that

Magneto-Optical Indicator Film (MOIF) Microscopy of Granular and Layer Structures (Abstract)

April 1, 1996
Author(s)
Valerian I. Nikitenko, V S. Gornakov, L M. Dedukh, A F. Khapikov, Lawrence H. Bennett, Robert D. McMichael, L Swartzendruber, Alexander J. Shapiro, Michael J. Donahue, V N. Matveev, V I. Levashov
We report on the possibilities of application of magneto-optical indicator film (MOIF) technique for visualization and direct experimental study in real time of the magnetization processes and nondestructive characterization of the quality of magnetic thin
