Community Resilience Estimates
Data provided by United States Census Bureau
The Community Resilience Estimates track how socially vulnerable every neighborhood in the United States is to the impacts of a disaster. The Community Resilience Estimates use American Community Survey microdata and Population Estimates Program data to measure the ability of individuals and households to absorb the external stresses of the impacts of a disaster.

Python tools for OpenFOAM simulations of fused filaments in embedded 3D printing, Version 1.2.0
Data provided by National Institute of Standards and Technology
In embedded 3D printing, a nozzle is embedded into a support bath and extrudes filaments or droplets into the bath. Using OpenFOAM, we simulated the extrusion of filaments and droplets into a moving bath, for single filaments, single filaments being disturbed by a nozzle, and printing pairs of filaments. OpenFOAM is an open source computational fluid dynamics solver.

OpenFOAM simulations of filament fusion in embedded 3D printing
Data provided by National Institute of Standards and Technology
In embedded 3D printing, a nozzle is embedded into a support bath and extrudes filaments or droplets into the bath. However, moving the nozzle near an existing structure and writing new filaments can cause deformation and lack-of-fusion defects. Using OpenFOAM, we simulated what happens when a nozzle moves near an existing filament, and when a nozzle writes a second filament next to an existing filament. OpenFOAM is an open source computational fluid dynamics solver. This work used OpenFOAM 8 on a computing cluster. OpenFOAM input files were generated using Python 3.7.

Dataset for: A technique for in-situ displacement and strain measurement with laboratory-scale X-ray Computed Tomography
Data provided by National Institute of Standards and Technology
This record provides raw and post-processed data used in the associated paper "A technique for in-situ displacement and strain measurement with laboratory-scale X-ray Computed Tomography." The codes used are provided in a separate software publication "SerialTrackXR", also referenced. The data consist of 3D X-ray computed tomography (X-ray CT) scans, projection images, and load/displacement data of two additively manufactured tensile test coupons made from IN718 with different processing conditions.

Characterization of a Frequency Converter Based on a Superconducting Coplanar Waveguide, IMS 2024
Data provided by National Institute of Standards and Technology
We plan to present a technique for implementing a frequency doubler in NbTiN on silicon for operation in a cryogenic environment at IMS 2024. The kinetic inductance of a superconducting coplanar waveguide is exploited for efficient frequency conversion, while the fabrication allows for co-location with other cryogenic circuits. A conversion efficiency greater than 10% is demonstrated at a frequency of 9.87 GHz, offering lower input power requirements and competitive conversion efficiencies relative to other state-of-the-art solutions.

Cutting Force Monitoring Experiment 02
Data provided by National Institute of Standards and Technology
An experiment was set up at the Oak Ridge National Laboratory (ORNL) to test methods for estimating the cutting forces in real time within machine tools for any spindle speed, force profile, tool type, and cutting conditions. Before cutting, a metrology suite and instrumented tool holder were used to induce magnetic forces during spindle rotation, while on-machine vibrations, magnetic forces, and error motions were measured for various combinations of speeds and forces.

Code for SerialTrack-XR particle tracking
Data provided by National Institute of Standards and Technology
This repository contains scripts for running a custom implementation of "SerialTrack" designed for 2D X-ray projection images taken during in situ micro-X-ray computed tomography (XCT) experiments. The particle tracking-based technique allows for surface displacement and strain fields to be measured during, for example, mini-tensile test motions.
