Associating Disaster Deaths with Risk Profiles

September 28, 2020
Author(s)
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

Machine Learning Methods for Predicting Seismic Retrofit Costs

September 23, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David Butry, Steven L. McCabe
Aging building clusters all around the world, especially in high seismic regions, will require a retrofit approach to improve the resilience of the built environment. One of the main challenges of retrofitting existing buildings is the associated cost

Open Standards for Flexible Discrete Manufacturing in the Model-Based Enterprise

September 23, 2020
Author(s)
Mark White, Eric Holterman, Tim Bakker, Larry Maggiano
The Commonwealth Center for Advanced Manufacturing is currently constructing an open, standards-based flexible manufacturing cell. The manufacturing cell must take in a product definition, machine the defined part, inspect it, rework as necessary, and
