Methods to evaluate 3D lidars used for automated driving

January 1, 2025
Author(s)
Prem Rachakonda, Abhilash Mane, Craig I. Schlenoff, Kamel S. Saidi
Evaluating perception sensor systems for on-road autonomous vehicles is still fraught with ambiguity due to the varying and dynamic environmental factors that these vehicles encounter. The critical safety of on-road AV operations is heavily dependent on

VOC Emission Rates from an Indoor Surface Using a Flux Chamber and PTR-MS

December 1, 2024
Author(s)
Han Huynh, Jenna Ditto, Michael Link, Dustin Poppendieck, Delphine Farmer, Marina Vance, Jonathan Abbatt
Arising from the Chemical Assessment of Surfaces and Air (CASA) 2022 study at the NIST Net-Zero Energy Residential Test Facility (NZERTF), this paper presents the first evaluation of indoor surface emissions to a house measured with a surface flux chamber

Deformation of PMMA samples in cone calorimeter and anaerobic gasification experiments

October 20, 2024
Author(s)
Karen De Lannoye, Isaac Leventon, Lucie Hasalova, Alexander Belt, Ernst-Arndt Reinecke, Lukas Arnold
16 Cone calorimetry and anaerobic gasification experiments are often used to assess material 17 flammability of bench-scale (coupon sized) samples in response to well-characterized external radiant 18 heating. In this project, it has been observed that the

A Guide to the Smart Investment Tools

October 10, 2024
Author(s)
Douglas Thomas, Joshua D. Kneifel, Purav Parekh
This report serves as a guide to the Smart Investment Tool and Smart Investment Tool Express (SITExpress). These tools aid a user in conducting an investment analysis with a focus on those in the manufacturing industry; however, the methods can be used for

Path-integral calculation of the third dielectric virial coefficient of helium based on ab initio three-body polarizability and dipole surfaces

October 10, 2024
Author(s)
Giovanni Garberoglio, Allan H. Harvey, Jakub Lang, Michal Przybytek, Michal Lesiuk, Bogumil Jeziorski
We develop a surface for the electric dipole moment of three interacting helium atoms and use it, together with state-of-the-art potential and polarizability surfaces, to compute the third dielectric virial coefficient, Cε, for both 4He and 3He isotopes

Forecasting demand data for critical materials

October 9, 2024
Author(s)
Kyle Foster, Nehika Mathur
Gallium, Indium and Cobalt are critical materials that vital to ramping up the adoption of clean energy technologies such as solar photovoltaics (PVs), electric vehicles (EVs) and wind turbines (WTs). Like other critical materials, they too are prone to

Gated InAs quantum dots embedded in surface acoustic wave cavities for low-noise optomechanics

October 8, 2024
Author(s)
Zixuan Wang, Ryan DeCrescent, Poolad Imany, Joseph Bush, Sae Woo Nam, Richard Mirin, Kevin L. Silverman
Self-assembled InAs quantum dots (QDs) are promising optomechanical elements due to their excellent photonic properties and sensitivity to local strain fields. Microwave-frequency modulation of photons scattered from these efficient quantum emitters has

Speed of Sound for Understanding Metals in Extreme Environments

October 7, 2024
Author(s)
Elizabeth Rasmussen, Boris Wilthan
Knowing material behavior is crucial to successful design, especially given the growing number of next-generation energy, defense, and manufacturing systems operating in extreme environments. Specific applications for materials in extreme environments

Report on Secure Hardware Assurance Reference Dataset (SHARD) Program

October 1, 2024
Author(s)
Paul E. Black, Vadim Okun
Significant vulnerabilities have been found in chips. Computer programs and methods have been developed to prevent, find, and mitigate them. We proposed Secure Hardware Assurance Reference Dataset (SHARD) as a repository of reference examples (test cases)

TREC 2015 Dynamic Domain Track Overview

October 1, 2024
Author(s)
Ian Soboroff, Hui Yang, John Frank
Search tasks for professional searchers, such as law enforcement agencies, police officers, and patent examiners, are often more complex than open domain Web search tasks. When professional searchers look for relevant information, it is often the case that

A Data Protection Approach for Cloud-Native Applications

September 30, 2024
Author(s)
Ramaswamy Chandramouli, Wesley Hales
This document addresses the need for effective data protection strategies in the evolving realm of cloud-native network architectures, including multi-cloud environments, service mesh networks, and hybrid infrastructures. By extending foundational data

State of the Art and Research Needs in Design for Tornadoes: Structural Engineering Institute Workshop Report

September 30, 2024
Author(s)
Donald Scott, Jennifer Goupil, Shane Crawford, Alex Griffin, Cherylyn Henry, Marc Levitan, Franklin Lombardo, John van de Lindt, Peter Vickery
The Structural Engineering Institute (SEI) has a long history of working with NIST and other federal partners to improve ASCE/SEI 7 Minimum Design Loads and Associated Criterial for Buildings and Other Structures, the national loading standard. Following

Summary Report: CHIPS R&D Program Standards Summit
