Nanofabrication via Atom Optics with Chromium

February 10, 1997
Author(s)
Jabez J. McClelland, W Anderson, Robert Celotta
Through the use of light forces exerted by near-resonant laser light, chromium atoms are focused as they deposit onto a substrate, forming nanometer-scale structures on the surface. The laser light is in the form of a standing wave, in which each node acts

Analysis of High Bay Hangar Facilities for Fire Detector Sensitivity and Placement.

February 1, 1997
Author(s)
Daniel L. Lowe, Kathy A. Notarianni, William D. Davis, J E. Gott
Current guidelines for designing fire protection systems for aircraft hangars were developed with the primary objective of saving the building, and with less consideration given to minimizing damage to the hangar's contents. The high cost of modern

Automation and Testing of Character-Graphic Programs

February 1, 1997
Author(s)
Don E. Libes
This paper describes a technique that allows automation and testing of character graphic programs using existing public-domain tools. Specifically, Tcl, Tk, and Expect are augmented with a terminal emulator in order to build a screen representation in

Generalized Message Passing in a Virtual Reality Application

February 1, 1997
Author(s)
David W. Flater
The message passing semantics of an object-oriented programming language is one of the factors that determines how powerful the language is. Whether it is referred to as a method invocation, a dispatching call, an event, a signal, or something else, each

Laser Collimation of a Chromium Beam

February 1, 1997
Author(s)
R E. Scholten, R Gupta, Jabez J. McClelland, Robert Celotta, M Levenson, M Vangel
We have studied laser collimation of a chromium atomic beam using a transverse polarization gradient cooling scheme. We present detailed measurements of the angular distribution of atoms on the beam axis, over a broad range of laser intensities and

Models for Integrating Scheduling and Shop Floor Data Collection

February 1, 1997
Author(s)
Frank H. Riddick, V. Lourenco
Increasing shop floor efficiency through scheduling has become one of the major concerns of manufacturing companies. Two of the problems that manufacturers have to overcome are 1) it is difficult to input the information needed for scheduling into the
