Web-Based System for Design Artifact Modeling

July 1, 2000
Author(s)
Simon Szykman, J Racz, Christophe Snowden, Ram D. Sriram
Modern engineering industry is relying more and more on the use of knowledge in product development. The NIST-Design Repository Project, at NIST, is working to develop infra-structural technologies to support the use of design repositories in industry.

Zoltan: Data-Management Services For Parallel Applications Developer's Guide

June 30, 2000
Author(s)
K Devine, B Hendrickson, E Boman, M St. John, C Vaughan, William F. Mitchell
The Zoltan Dynamic Load-Balancing Library provides critical capability to a number of parallel applications. Zoltan includes a suite of algorithms for dynamically computing partitions of problems over sets of processors; geometric, tree-based and graph

Mitigating Emerging Hacker Threats

June 28, 2000
Author(s)
Peter M. Mell, John P. Wack
[For the latest information on vulnerabilities, see the National Vulnerability Database, nvd.nist.gov] It seems that every week, computer security organizations are issuing press releases concerning the latest hacker attack. Some sound dangerous, like the

Mosquito Noise in MPEG-compressed Video: Test Patterns and Metrics

June 24, 2000
Author(s)
Charles D. Fenimore, John M. Libert, Peter Roitman
Mosquito noise is a time dependent video compression impairment in which the high frequency spatial detail in video images having crisp edges is aliased intermittently. A new synthetic test pattern of moving spirals or circles is described which generates

Public Key Infrastructures for the Financial Services Industry

June 21, 2000
Author(s)
William E. Burr, K L. Lyons-Burke
This paper addresses how financial institutions can use a Public Key Infrastructure (PKI) and some of the problems they may face in the process. PKI is an emerging cryptographic technology that is badly needed to realize the potential of information

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

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
