Data for Room Fire Model Comparisons

August 1, 1991
Author(s)
Richard D. Peacock, S Davis, Vyto Babrauskas
With the development of models to predict fire growth and spread in buildings, there has been a concomitant evolution in the measurement and analysis of experimental data in real-scale fires. This report presents the types of analyses that can be used to

Numerical Experiments in Scattering by a Dielectric Wedge

January 1, 2003
Author(s)
Egon Marx
A general discussion of the scattering of plane monochromatic waves by dielectric wedges precedes this paper. Numerical solutions of the problem of scattering by a dielectric wedge of finite cross section, with special emphasis on the divergent behavior of

NIST Roadmap Toward Criteria for Threshold Schemes for Cryptographic Primitives

July 7, 2020
Author(s)
Luis Brandao, Michael S. Davidson, Apostol T. Vassilev
This document constitutes a preparation toward devising criteria for the standardization of threshold schemes for cryptographic primitives by the National Institute of Standards and Technology (NIST). The large diversity of possible threshold schemes, as

Comparison of CFAST Predictions to Real Scale Fire Tests

October 15, 1996
Author(s)
Walter W. Jones, J. L. Bailey, P. A. Tatem, Glenn P. Forney
This paper describes a new algorithm of the Consolidated Fire Growth and Smoke Transport (CFAST) fire model and compares to data from real scale fire tests conducted onboard the ex-USS SHADWELL, the Navy's R&D Damage Control Platform. The new phenomenon

Conformance Testing and Specification Management

June 1, 1996
Author(s)
James A. St Pierre, Selden Stewart, Kevin G. Brady
This is the final report for the second year of a joint project between the National Institute of Standards and Technology (NIST) and SEMATECH. It presents the results from investigation in two areas that were proposed in the first year report: conformance

dint u say that: Digital Discourse, Digital Natives and Gameplay

Author(s)
Theresa O'Connell, John D. Grantham, Wyatt Wong, Kevin Workman, Alexander Wang
Traditional, new and modified discourse analysis methods were applied to a corpus of 858 discrete gameplay discourse events disclosing discourse characteristics during collaborative problem solving. Four teams of four digital natives each played

Security Property Verification by Transition Model

January 31, 2025
Author(s)
Chung Tong Hu
Verifying the security properties of access control policies is a complex and critical task. The policies and their implementation often do not explicitly express their underlying semantics, which may be implicitly embedded in the logic flows of policy

Towards a Digital Twin of a Robot Workcell: Standards and Methods

October 28, 2024
Author(s)
Deogratias Kibira, Guodong Shao, Rishabh Venketesh
Digital twins are poised to improve the way products are designed, manufactured, and managed throughout their life cycle. However, implementing digital twins for small and medium manufacturers (SMM) has been a challenge mainly due to lack of resources and

Robust feature design for early detection of ball screw degradation

October 1, 2024
Author(s)
Xu Han, Marcella Miller, Gregory Vogl, Guanyu Chen, Xiaodong Jia
The ball screw is a critical device for precision linear motion control that has widespread applications in industrial robots, computer numerical control (CNC) machines, and high-precision leveling systems, among others. Because high-precision positioning

Estimations of Photopheresis and Thermophoresis Impacts on Soot Particle Velocity

March 12, 2024
Author(s)
Emma Veley, Amy Mensch, Ryan Falkenstein-Smith, Thomas Cleary
The dissemination of soot particles onto surfaces in a compartment fire is affected by local radiation and temperature gradients. Subsequently, any deposition model must account for the influence of photopheresis and thermophoresis on the deposition

Evaluation of Formation Enthalpies of C3 and C4 Brominated Hydrocarbons: Bringing Together Classical Thermodynamics, Modern Mass-Spectroscopy, and High-Level Ab Initio Calculations

February 7, 2024
Author(s)
Eugene Paulechka, Andrei F. Kazakov
The enthalpies of formation of brominated C3–C4 hydrocarbons were critically evaluated using experimental data sources ranging from classical thermodynamics methods to modern high-precision mass spectrometry and reported in a time span of a century. The

A Characterization of OFDMA Uplink Activation for Industrial Applications

February 5, 2024
Author(s)
Karl Montgomery, Rick Candell
This report serves to determine how Orthogonal Frequency Division Multiple Access (OFDMA) is triggered in commercial IEEE 802.11ax (Wi-Fi 6) access points for industrial application scenarios. It presents an overview of OFDMA and how it works in IEEE 802

Photonic Online Learning

January 9, 2024
Author(s)
Sonia Buckley, Adam McCaughan, Bakhrom Oripov
Training in machine learning necessarily involves more operations than inference only, with higher precision, more memory, and added computational complexity. In hardware, many implementations side-step this issue by designing "inference-only" hardware
