June 1, 1997
Author(s)
S G. Lias, Anzor I. Mikaia, O D. Sparkman, Stephen Stein, Vladimir G. Zaikin
Achievements in the development of the NIST/EPA/NIH mass spectral library is reported. Statistical data on the content of the library is presented,the quality control procedures are described, the roles of computer methods and manual procedures in data

Evaluating Performance Of Approximate Radiation Models Against Photon Monte Carlo Line-By-Line Benchmark For Fire Simulation

June 15, 2025
Author(s)
Chandan Paul, Somesh Roy, Johannes Sailer, Fabian Br"annstr"om, Mohamed Mohsen Ahmed, Arnaud Trouv'e, Hadi Bordbar, Simo Hostikka, Randall McDermott
The Measurement and Computation of Fire Phenomena (MaCFP) radiation working group previously provided benchmark radiation data for two fire configurations using the Photon Monte Carlo Line-by-Line (PMC-LBL) radiation model. This study evaluates the

Uncertainties in Swift hardening law parameters and their influence on the flow stress and the hole expansion behavior of dual phase (DP600) steel specimens

January 4, 2023
Author(s)
Dilip K. Banerjee, Kali Prasad, Deepak Kumar, Krishnaswamy Hariharan
Swift hardening law is one of the most widely used phenomenological models to describe flow stress-strain behavior in sheet metal forming simulations. In the present study, a statistical approach was used to investigate the effect of material property

Trapped Ion Quantum Information Processing with Squeezed Phonons

January 24, 2019
Author(s)
Wenchao Ge, Brian Sawyer, Joseph W. Britton, Kurt Jacobs, John Bollinger, Michael Foss-Feig
Trapped ions offer a pristine platform for quantum computation and simulation, but improving their coherence remains a crucial challenge. Here, we propose and analyze a new strategy to enhance the coherent interactions in trapped-ion systems via parametric

Quadrature Histograms in Maximum Likelihood Quantum State Tomography

August 22, 2018
Author(s)
Leonardo E. Silva, Scott Glancy, Hilma H. Macedo De Vasconcelos
Quantum state tomography aims to determine the quantum state of a system from measured data and is an essential tool for quantum information science. When dealing with continuous variable quantum states of light, tomography is often done by measuring the

Application of the Complex Kohn Variational Method to Attosecond Spectroscopy

August 6, 2018
Author(s)
Barry I. Schneider, Nicholas Douguet, Luca Argenti
The complex Kohn (CK) variational method is extended to compute light-driven electronic transitions between continuum wavefunctions in atomic and molecular systems. This development enables the study of multiphoton processes in the perturbative regime for

Navigating Unmountable Media with the Digital Forensics XML File System

May 31, 2018
Author(s)
Alexander J. Nelson, Alexandra Chassanoff, Alexandra Holloway
Some computer storage is non-navigable by current general-purpose computers. This could be because of obsolete interface software, or a more specialized storage system lacking widespread support. These storage systems may contain artifacts of great

Experimental scattering matrix for lunar regolith simulant JSC-1A at visible wavelengths

March 8, 2018
Author(s)
Edward J. Garboczi, Ann C. Chiaramonti Debay, Thomas V. Lafarge, O Munoz, J Escobar-Cerezo, D Guirado, JC Gomez-Martin, Jay Goguen, F Moreno
We present the experimental scattering matrix as a function of the scattering angle of the lunar soil simulant JSC-1A. The measurements were performed at 488 nm, 520 nm and 647 nm, covering the range of scattering angles from 3o to 177o. The size

Structural Analysis of a High-Rise Composite Frame Exposed to Fire

February 19, 2017
Author(s)
Dat Duthinh, Kuldeep Prasad
This paper presents a simplified, planar analysis of World Trade Center Tower 1 (WTC1), starting from a computer simulation of the fire using computational fluid dynamics, and progressing through a thermal and a structural analysis of the damaged structure

Modeling of Suspension Flow in a Pipe Geometry and Rheometers

May 18, 2016
Author(s)
Nicos Martys, Chiara F. Ferraris, William L. George
Abstract Measurement and prediction of the flow of suspensions like cement based materials represents a significant challenge for both the experimentalist and modeler. In this paper, results of a computational study of suspension flow in a pipe and a

Stochastic Modeling and Simulation of Marginally Trapped Neutrons

May 20, 2014
Author(s)
Kevin J. Coakley
For a magnetic trapping experiment, I present an efficient method for simulating experimental beta −decay rates which accounts for loss of marginally trapped neutrons due to wall collisions and other possible loss mechanisms. Monte Carlo estimates of time

Guidelines for Protecting Basic Input/Output System (BIOS) Firmware

June 28, 2011
Author(s)
Shirley M. Radack
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-147, BIOS Protection Guidelines: Recommendations of the National Institute of Standards and Technology. The publication was written by David Cooper, William Polk

Approximating Periodic Solutions of Autonomous Delay Differential Equations

November 30, 2006
Author(s)
David E. Gilsinn
Machine tool chatter has been characterized as isolated periodic solutions or limit cycles of delay differential equations. Determining the amplitude and frequency of the limit cycle is sometimes crucial to understanding and controlling the stability of

A Fundamental Equation for Trifluoromethane (R-23)

December 1, 2003
Author(s)
S G. Penoncello, Eric Lemmon, R. T. Jacobsen, Z Shan
A formulation for the thermodynamic properties of trifluoromethane R-23) is presented. The equation is valid for single-phase and saturation states from the triple point (1 18.02 K) to 475 K at pressures up to 120 MPa. The formulation includes an equation
