Seismic Evaluation of a 2-Story Cold-Formed Steel Framed Building using ASCE 41-17

September 29, 2020
Author(s)
Matthew S. Speicher, Ivana Olivares, Benjamin W. Schafer
The objective of this report is to assess the adequacy of new provisions in ASCE 41 for seismic assessment of cold-formed steel framed buildings. A two-story cold-formed steel (CFS) framed building that has been designed to contemporary seismic standards

A NIST-Hosted Virtual Workshop on Measuring SARS-CoV-2 in Wastewater and Fecal Material: A Call for Standards

Kamran Sayrafian, Masoud Roudneshin, Amir G. Aghdam
Recent advancements in micro-electronics have led to the development of miniature-sized wearable sensors that can be used for a variety of health monitoring applications. These sensors are typically powered by small batteries which could require frequent

Associating Disaster Deaths with Risk Profiles

September 28, 2020

Stanley W. Gilbert, Jennifer F. Helgeson, David H. Webb, Juan F. Fung, Anand M. Kandaswamy
In this paper we set out to identify which “risk profiles” contribute most to deaths in disasters. A risk profile represents an identifiable group of people who would be at risk of death in a disaster through some mechanism. Four risk profiles were

Kinetics of Isopropanol Decomposition and Reaction with H atoms from Shock Tube Experiments and Rate Constant Optimization using the Method of Uncertainty Minimization using Polynomial Chaos Expansions (MUM-PCE)

September 28, 2020
Author(s)
Laura A. Mertens, Jeffrey A. Manion
Recent interest in isopropanol (2-propanol, C3H¬7OH) combustion stems from its potential as a renewable biofuel. Here, we report shock tube investigations of isopropanol decomposition and reaction with H atoms at (918 to 1212) K and (158 to 484) kPa

QARTOD - Prospects for Real-Time Quality Control Manuals, How to Create Them, and a Vision for Advanced Implementation

September 28, 2020
Author(s)
Mark Bushnell, Kathleen Bailey, Julie Bosch, Eugene Burger, Jennifer Dorton, Regina Easley, Bob Heitsenrether, Jeff King, Karen Grissom, Mario Tamburri, Julianna Thomas, Christoph Waldmann
The U.S. Integrated Ocean Observing System (IOOS) Quality Assurance / Quality Control of Real- Time Oceanographic Data (QARTOD) Project marshaled hundreds of volunteer subject matter experts to identify tests to evaluate real-time data quality by

Anteater: Interactive Visualization for Program Understanding

September 24, 2020
Author(s)
Rebecca Faust, Kartherin Isaacs, William Z. Bernstein, Michael Sharp, Carlos Scheidegger
Debugging is famously one the hardest parts in programming. In this paper, we tackle the question: what does a debugging environment look like when we take interactive visualization as a central design principle? We introduce Anteater, an interactive

Firearm examination: Examiner judgments and computer-based comparisons

September 24, 2020
Author(s)
Erwin J. Mattijssen, Cilia Witteman, Charles Berger, Xiaoyu Alan Zheng, Johannes A. Soons, Reinoud Stoel
Forensic firearm examination provides the court of law with information about the source of fired cartridge cases. We assessed the validity of source decisions of a computer-based method and of 73 firearm examiners who compared breechface and firing pin

Electron-Phonon Coupling and Superconductivity in the Doped Topological Crystalline Insulator (Pb 0.5 Sn 0.5 _) 1-x In x Te

September 23, 2020
Author(s)
A. Sapkota, Y. Li, B. L. Winn, A. Podlesnyak, Guangyong Xu, Zhijun Xu, Kejing Ran, Tong Chen, Jian Sun, Jinsheng Wen, Lihua Wu, Jihui Yang, Qiang Li, G. D. Gu, J. M. Tranquada
We present a neutron scattering study of phonons in single crystals of (Pb 0.5Sn 0.5) 1−xIn xTe with x = 0 (metallic, but nonsuperconducting) and x = 0.2 (nonmetallic normal state, but superconducting). We map the phonon dispersions (more completely for x
