Configurational Temperature: Verification of Monte Carlo Simulations

October 1, 1998
Author(s)
B D. Butler, G Ayton, O G. Jepps, D J. Evans
A diagnostic that is useful for checking the algorithmic correctness of Monte Carlo computer programs is presented. The check is made by comparing the Boltzmann temperature input to the program and used to accept or reject moves, with the configurational

Conformance Testing Object-Oriented Frameworks Using JAVA

October 1, 1998
Author(s)
Kevin G. Brady, James A. St Pierre
This paper details the assumptions, decision processes, and conclusions reached during the development and implementation of a Conformance Testing Tool using the JAVA [JAVA] programming language, and the Object Management Group's (OMG's) Common Object

Critical Viscosity of Xenon: Surprises and Scientific Results

October 1, 1998
Author(s)
Robert F. Berg, Michael R. Moldover, G A. Zimmerli
The Critical Viscosity of Xenon (CVX) experiment, which flew on board Space Shuttle flight STS-85 in August 1997, measured the viscosity of xenon near the liquid-vapor critical point. Very close to the critical temperature (T c = 290 K), the viscosity Η of

Dictionary of Algorithms and Data Structures

October 1, 1998
Author(s)
Paul E. Black
This web site is hosted by the Software and Systems Division, Information Technology Laboratory, NIST. Development of this dictionary started in 1998 under the editorship of Paul E. Black. This is a dictionary of algorithms, algorithmic techniques, data

Dispersed Liquid Agent Fire Suppression Screening Method (NISTIR 6242)

October 1, 1998
Author(s)
Jiann C. Yang, Michelle K. Donnelly, N C. Prive, William L. Grosshandler
The recent ban on halon 1301 production (as a result of its ozone depleting potential) has resulted in an extensive search for replacements and alternatives. The applications of fire suppression efficiency screening methods constitute an important aspect

Effect of Hydrogen on Pb(Zr,Ti)O 3 -Based Ferroelectric Capacitors

October 1, 1998
Author(s)
S R. Perusse, C W. Tipton, H D. Drew, T Venkatesan, R Ramesh, D B. Romero, V B. Podobedov, A Weber
The properties of ferroelectric films are known to degrade when subjected to hydrogen in forming gas anneals. Earlier studies have attributed this degradation to the loss of oxygen from these films during these anneals. In this study, we show that though

Enhancement of R123 Pool Boiling by the Addition of Hydrocarbons

October 1, 1998
Author(s)
Mark A. Kedzierski
This paper present pool boiling heat transfer data for ten different R123/hydrocarbon mixtures. The data consisted of pool boiling performance of a GEWA-T TM surface for pure R123 and for ten dilute solutions of five different hydrocarbons: (1) pentane, (2

Evaluation of Uncertainties in Fundamental Radiometric Measurements

October 1, 1998
Author(s)
Benjamin K. Tsai, Bettye C. Johnson
The uncertainty of measurements is critical in furthering the development of radiometric science and acquiring an increased understanding of its principles. Proper analysis of measurement uncertainties provides an indication of how well the measurements

Federal Register Document Image Database 25, Volume 1

October 1, 1998
Author(s)
Michael D. Garris, Stanley Janet, W Klein
A new, fully-automated process has been developed at NIST to derive ground truth for document images. The method involves matching optical character recognition (OCR) results from a page with typesetting files for an entire book. Public domain software

Ferromagnetic Resonance Studies of NiO-Coupled Thin Films of Ni 80 Fe 20

October 1, 1998
Author(s)
Robert D. McMichael, Mark D. Stiles, P J. Chen, William F. Egelhoff Jr.
This paper describes ferromagnetic resonance (FMR) and magnetoresistive measurements of thin magnetic films coupled to antiferromagnetic films. First, FMR results for films of Ni 80Fe 20 show that coupling to NiO produces the angular variation in the

Flammability Studies of Polymer Layered Silicate (Clay) Nanocomposites (NISTIR 6242)

October 1, 1998
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, Marc R. Nyden, James E. Brown, C L. Jackson, S M. Lomakin, E P. Giannelis, E Manias
In the pursuit of improved approaches to fire retarding polymers a wide variety of concerns must be addressed, in addition to the flammability issues. First, the low cost of commodity polymers requires that the fire retardant (FR) approach also be of low

Gapped Arresters Revisited: A Solution to Cascade Coordination

October 1, 1998
Author(s)
A. Mansoor, Francois D. Martzloff, K. O. Phipps
This paper provides a brief perspective on how the coordination of cascaded surge-protective devices (SPDs) has become an issue. We propose an approach where the 'ancient' technology of gapped arresters may well be the answer to the dilemma of the

GenCAM Syntax Checker

October 1, 1998
Author(s)
Michael McLay
A conformance test module (CTM) for the GenCAM file format is being developed by National Institute of Standards and Technology to support an industry effort to develop the GenCAM standard. GenCAM is a product data exchange standard for information used in

High Frequency Limitations of the JEDEC 123 Guideline

October 1, 1998
Author(s)
Dylan F. Williams
Abstract: This paper assesses certain systematic high frequency measurement errors inherent in the procedures described in the JEDEC 123 Guideline for Measurement of Electronic Package Inductance and Capacitance Model Parameters.
