A Modular Architecture for STEP

Author(s)
Allison Barnard Feeney, David M. Price
This paper presents the current direction in the architecture of STEP (STandard for the Exchange of Product model data, ISO 10303). STEP is an international...

Scalar Dissipation in Axisymmetric Jets

Author(s)
William M. Pitts
Scalar dissipation, defined as twice the product of the molecular diffusion coefficient and the local gradient of the mixture fraction taken as a dot product...

A Knowledge-Based Inspection Workstation

Author(s)
Elena R. Messina, John A. Horst, Thomas R. Kramer, Hui-Min Huang, Tsung-Ming Tsai, E Amatucci
We are building an inspection workstation development environment to use as a testbed for understanding what types of knowledge, e.g., data, algorithms, and...

Author(s)
Robert E. Vest, L R. Canfield, Mitchell L. Furst, R M. Graves, A D. Hamilton, L R. Hughey, Thomas B. Lucatorto, R P. Madden
The National Institute of Standards and Technology (NIST) serves the growing ultraviolet user community by providing calibration services throughout the...

Experiments in Dilute Atomic Bose-Einstein Condensation

Author(s)
Eric A. Cornell, J R. Ensher, C E. Wieman
Why BEC? - In the month we began writing this paper, fourteen papers on the explicit topic of Bose-Einstein condensation (BEC) in a dilute gas appeared in the...

Thermophysical Properties of Process Gases

Author(s)
John J. Hurly, Michael R. Moldover
We measured the speed of sound in the process gases Cl 2, HBr, BCl 3, and in the surrogate gases SF 6, CF 4, and C 2F 6. The data range up to 475 K (200 C) and...
