Development of NIST Standard Bullets and Casings Status Report

November 1, 2000
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Alim A. Fatah
In April 1998, two prototype standard bullets were developed at the National Institute of Standards and Technology (NIST). In October 1999, prototype standard casings were also developed at NIST. The standard bullets and casings are intended for use in

Challenges in Developing Environmentally Safe Heat Pumping Systems

July 1, 2000
Author(s)
David Didion, J S. Brown
The advent of the global warming crisis has brought about a viewpoint, in many governments, that the halogen family of refrigerants should be replaced, in part or in toto, by the so-called natural refrigerants. For this proposal to be valid it is necessary

Effects of Cement PSD on Porosity Percolation and Self-Desiccation

August 1, 1999
Author(s)
Dale P. Bentz
The degree of self-desiccation in field concrete depends on the availability of external water to replace that consumed due to the chemical shrinkage that occurs during cement hydration. As the cement hydrates, the capillary porosity depercolates

Analytic Solution for a Non-Axisymmetric Isothermal Dendrite

March 1, 1999
Author(s)
Geoffrey B. McFadden, Sam R. Coriell, R F. Sekerka
The Ivantsov solution for an isothermal paraboloidal dendrite growing into a pure, undercooled melt provides a relation between the bulk undercooling and a dimensionless product, the Peclet number, of the growth velocity and tip radius of the dendrite

Cryptography Standards and Infrastructures for the Twenty-First Century

September 17, 1998
Author(s)
Shirley M. Radack
This bulletin reports on the progress being made by NIST and by its government and industry partners to advance the development of electronic commerce systems in which users will have confidence. There are efforts underway to update existing standards for

Personal Identification From Mugshot Ear Images

March 1, 1998
Author(s)
F E. McFadden
This work establishes the high value of ear images for personal identification from mugshot data, using the NIST database of police mugshots. It starts with a method for boundary analysis based on two innovations. First edge analysis is performed only

Field Modeling: Simulating the Effects of HVAC Induced Air Flow From Various Diffusers and Returns on Detector Response. International Fire Detection Research Project. Year 4 Report/Data

January 1, 1998
Author(s)
J H. Klote, William D. Davis, Glenn P. Forney, Richard W. Bukowski
Rapid activation of fire protection systems in response to a growing fire is one of the important factors required to provide for life safety and property protection. Airflow due to the heating, ventilating and air conditioning (HVAC) system can

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

Unified Process Specification Language: Requirements for Modeling Process

January 1, 1996
Author(s)
Craig I. Schlenoff, Amy Knutilla, Steven R. Ray
A wide range of applications deal with the manipulation and expression of collections of activities. Examples include project management, workflow management, business process reengineering, product realization process modeling, manufacturing process

Comparison of a Fractal Smoke Optics Model With Light Extinction Measurements

January 1, 1994
Author(s)
R A. Dobbins, George W. Mulholland, Nelson P. Bryner
Optical cross-sections of carbonaceous aggregates (smoke) formed by combustion sources have been computed based on fractal concepts. Specific extinction depends upon the primary particle size, the structure of the aggregate as represented by the fractal

Coexistence calculation using the Isothermal-Isochoric Integration Method

Author(s)
Seyed M. Razavi, Richard A. Messerly, J. R. Elliott
In this work, an isothermal-isochoric integration (ITIC) method is proposed and tested as a viable method for vapor pressure calculation by molecular simulation. Several tests were carried out to validate the method which resulted in less than 1 %

Analysis of the Happyland Social Club Fire With HAZARD I

December 31, 1992
Author(s)
Richard W. Bukowski, Robert C. Spetzler
The paper presents the reconstruction of the Happyland Social Club fire using the HAZARD I fire hazard assessment method along with an examination of four potential mitigation strategies: automatic sprinklers, a door at the base of the stairway to the

Systems Engineering Foundations of Software Systems Integration

August 1, 2002
Author(s)
Peter O. Denno, Allison Barnard Feeney
This paper concerns how engineering capability should be factored into problem solving agencies for application to software systems integration tasks, and how the results produced by these agencies should be communicated and integrated into a system

Round Robin Determination of Power Spectral Densities of Different Si Wafer Surfaces

March 1, 1998
Author(s)
Egon Marx, I J. Malik, Y Strausser, T Bristow, N Poduje, J C. Stover
Power spectral densities (PSDs) were used to characterize a set of surfaces over a wide range of lateral as well as perpendicular dimensions. Twelve 200-mm-diameter Si wafers were prepared and the surface finishes ranged from as-ground wafers to epitaxial

Characterizing Cell-Free Transcription and Translation Dynamics with Nucleic Acid-Based Assays

August 10, 2025
Author(s)
Fernanda Piorino Macruz de Oliveira, Chad Alan Sundberg, Elizabeth Strychalski, Eugenia Romantseva
Characterization of cell-free expression (CFE) systems must expand beyond single spectrophotometric measurements of a green fluorescent protein to provide meaningful metrics of system performance over the course of a CFE reaction and enable the development

The trace of heat: on the predictive power of modeling transient diffusion

June 26, 2025
Author(s)
Vijaya Holla, Jesse Redford, Philipp Kopp, Stefan Kollmannsberger
The paper at hand evaluates the validity of the transient heat equation with phase change and temperature-dependent coefficients as a model to predict the evolution of melt pools for rapid turnaround scan strategies in a laser powder bed fusion (PBF-LB)
