Technical Support for the Study of Droplet Interactions with Hot Surfaces

June 21, 2000
Author(s)
Jiann C. Yang
The main objective is to provide technical support (literature review on water additives, fluid property and possibly droplet impact data) for the study of the dynamics of droplet/surface and droplet/flame interaction and its effect on burning cessation to

Exclusion Limits on the WIMP-Nucleon Cross Section from the Cryogenic Dark Matter Search

Schnee, D. N. Seitz, P. Shestople, T. Shutt, Amy Smith, G. W. Smith, A. H. Sonnenschein, A. L. Spadafora, W. Stockwell, J. D. Taylor, Stephen White, S. Yellin, B. A. Young
The cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search for weakly interacting massive particles (WIMPs) via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS

Computation of Causal Characteristic Impedances

June 12, 2000
Author(s)
Dylan F. Williams, Ronald C. Wittmann
We develop a numerical method of determining the magnitude of characteristic impedance required by causal power-normalized circuit theories from its phase using a Hilbert-transform relationship. We also estimate the uncertainty in the method.

Two-Dimensional Hard Dumbbells. I. Fluctuating Cell Model

June 8, 2000
Author(s)
S Gay, James C. Rainwater, P D. Beale
We apply the fluctuating cell model to the calculation of free energies and pressures of high density phases of two-dimensional hard dumbells using the Metropolis algorithm to generate configurations in the NVT ensemble. The natural logarithm of the

Accurate Dimensional Metrology With Atomic Force Microscopy

June 1, 2000
Author(s)
Ronald G. Dixson, R Koning, Joseph Fu, Theodore V. Vorburger, Thomas B. Renegar
Atomic force microscopes (AFMs) generate three dimensional images with nanometer level resolution and, consequently, are used in the semiconductor industry as tools for sub-micrometer dimensional metrology. Measurements commonly performed with AFMs are

An Architecture and Tool for Large-scale System Control with a manufacturing system application

June 1, 2000
Author(s)
Hui-Min Huang, James S. Albus, William P. Shackleford, Harry A. Scott, Thomas R. Kramer, Elena R. Messina, Frederick M. Proctor
This paper describes a reference architecture that is applicable to multiple classes of large-scale, complex real-time control systems. An associated tool, Generic Shell, is also described. Generic Shell employs a set of code templates that facilitate

An XML Repository Architecture for STEP Modules

June 1, 2000
Author(s)
Joshua Lubell
NIST is developing a web-based repository to serve as the core of a modular environment for developers of STEP, a family of product data exchange standards. Modules are represented in the repository as XML, enabling them to be treated both as documentation

Analysis of Interconnection Networks and Mismatch in the Nose-to-Nose Calibration

June 1, 2000
Author(s)
Donald C. DeGroot, Paul D. Hale, M. Vanden Bossche, F. Verbeyst, Jan Verspecht
We analyze the input networks of the samplers used in the nose-to-nose calibration method. Our model demonstrates that the required input network conditions are satisfied in this method and shows the interconnection errors are limited to measurement

Analysis of Module Interaction in an OMAC Controller

June 1, 2000
Author(s)
John L. Michaloski
Machine controllers built from standardized software parts, commonly referred to as components or modules, have the greatest potential to reap open architecture benefits - including plug-and-play, reusability and extensibility. Modularity is the key to
