Quantum Algorithms for Quantum Field Theories

June 1, 2012
Author(s)
Stephen P. Jordan, Keith S. Lee, John Preskill
Quantum field theory reconciles quantum mechanics and special relativity, and plays a central role in many areas of physics. We develop a quantum algorithm to compute relativistic scattering probabilities in a massive quantum field theory with quartic self

Verification and Validation of CFAST, A Model of Fire Growth and Smoke Spread

February 19, 2017
Author(s)
Walter W. Jones, Richard D. Peacock, Glenn P. Forney, Paul A. Reneke
CFAST is a zone model capable of predicting the environment in a multi-compartment structure subjected to a fire. It calculates the time evolving distribution of smoke and fire gases and the temperature throughout a building during a user-specified fire

Collaboration Technologies for Global Manufacturing

October 1, 1999
Author(s)
Michelle P. Steves, Amy Knutilla
One impact of the globalization of manufacturing is the growing requirement for teams that are not co-located to collaborate using shared information. In this paper, we present our approach to instituting and assessing collaboration technologies for

IMPPY3D: Image Processing in Python for 3D Image Stacks

April 2, 2025
Author(s)
Newell Moser, Alexander Landauer, Orion Kafka
Image Processing in Python for 3D image stacks, or IMPPY3D, is a free and open-source software (FOSS) repository that simplifies post-processing and 3D shape characterization for grayscale image stacks, otherwise known as volumetric images, 3D images, or

EVAP-COND Simulation Tool with Optimization Refrigerant Circuitry

February 1, 2022
Author(s)
Piotr Domanski
EVAP-COND is a software package that contains simulation models for a finned-tube evaporator and condenser. The modeling scheme allows for specifying complex refrigerant circuits, modeling refrigerant distribution between these circuits, and accounting for

Secure Hash Standard (SHS)

National Institute of Standards and Technology (NIST), Elaine Barker
… both the transmitter and intended receiver of a message in computing and verifying a digital signature. [Supersedes FIPS …

Fire Dynamics Simulator (Version 3): Technical Reference Guide (NISTIR 6783)

November 1, 2001
Author(s)
Kevin B. McGrattan, Howard R. Baum, Ronald G. Rehm, Anthony P. Hamins, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The equations described in this document are a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an emphasis on

Translating Express to SQL: A User

January 1, 1990
Author(s)
Katherine C. Morris
This document describes the procedure used by the fedex sql software to translate an Express schema into the SQL statements which generate a relational database schema for storing STEP data. The program which loads a STEP physical file into the database is

The Thermodynamic Modeling of Multicomponent Phase Equilibria

December 1, 1997
Author(s)
Ursula R. Kattner
The present paper gives an overview of the CALPHAD method and recent progress made. First a brief history is given then the scope of phase diagram calculations is described. Thermodynamics descriptions most commonly used in the CALPHAD method are described

Uncertainties in Scaling Factors for ab Initio Vibrational Frequencies

September 1, 2005
Author(s)
Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker
Vibrational frequencies determined from ab initio calculations are often scaled by empirical factors. An empirical scaling factor partially compensates for the errors arising from vibrational anharmonicity and incomplete treatment of electron correlation

Molecular Spectroscopy

October 16, 2008
Author(s)
D R. Lide, A Weber
This is a revised and expanded version of an article that appeared in the 2nd edition of the Encyclopedia of Physics, R.G. Lerner and G.L. Trigg, eds. Topics covered include Infrared, Raman, rotational, vibration-rotational, and electronic spectra, as well

Creating Training Data for Scientific Named Entity Recognition with Minimal Human Effort

June 8, 2019
Author(s)
Roselyne B. Tchoua, Aswathy Ajith, Zhi Hong, Logan T. Ward, Kyle Chard, Debra Audus, Shrayesh N. Patel, Juan J. de Pablo, Ian Foster
Scientific Named Entity Referent Extraction is often more complicated than traditional Named Entity Recognition (NER). For example, in polymer science, chemical structure may be encoded in a variety of nonstandard naming conventions, and authors may refer

Towards a Hybrid Human-Computer Scientific Information Extraction Pipeline

Fire Dynamics Simulator (Version 3): User's Guide (NISTIR 6784)

November 1, 2001
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

The Automated Manufacturing Research Facility of the National Bureau of Standards

August 1, 1983
Author(s)
Cita M. Furlani, Ernest Kent, Howard Bloom, Charles R. McLean
A major facility for manufacturing research is being established at the National Bureau of Standards (NBS). NBS is addressing the measurement and standards needs for the automation of the small batch, discrete parts manufacturing industries. The Automated
