Projectile velocity data, from tests using the National Institute of Justice (NIJ) body armor standard (NIJ-0101.06) test threats, collected over a numbers of years at the NIST ballistics laboratory, that was used to assess the uncertainty associated with a chronograph/light screen system.

This data repository is meant to provide the supplementary files, tables, and figures included in the peer-reviewed research article entitled: "Sequence-based allelic variations and frequencies for 22 autosomal STR Loci in the Lebanese population".

The data correspond to the paper Practical Correlation-Matrix Approaches for Standardized Testing of Wireless Devices in Reverberation Chambers. Abstract: We extend the autocorrelation-based approaches currently used in standards to full correlation matrix-based approaches in order to identify correlation between both spatially adjacent and non-adjacent samples in reverberation-chamber measurements. We employ a scalar metric that allows users to identify the number of effectively uncorrelated samples in new types of stirring sequences.

Videos and .stl files from Synergistic Fire Resistance of Nanobrick Wall Coated 3D Printed Photopolymer Lattices.The videos are from the fire tests of 3D printed photopolymer parts, from which time series still images were acquired. In these tests, printed parts (with or without a nanocoating) are subjected to direct blowtorch exposure until part failure (defined as when the part shatters). Most videos include time after torch removal while the part continues to burn.The .stl files are the files used to 3D print the parts studied in this work.

The Diverse Community Excerpts are a set of tabular demographic data of households in the United States drawn from real records released in the American Community Survey, a product of the US Census Bureau. The data contain 24 features and are partitioned into three geographic regions: Boston area (7634 records), Dallas-Forth Worth area (9276 records), and US national (27254 records). The feature set is identical for all partitions, but the demographics vary radically between the geographic regions.

Data here contain and describe an open-source structured query language (SQLite) portable database containing high resolution mass spectrometry data (MS1 and MS2) for per- and polyfluorinated alykl substances (PFAS) and associated metadata regarding their measurement techniques, quality assurance metrics, and the samples from which they were produced. These data are stored in a format adhering to the Database Infrastructure for Mass Spectrometry (DIMSpec) project. That project produces and uses databases like this one, providing a complete toolkit for non-targeted analysis.

Python module 'optbayesexpt' uses optimal Bayesian experimental design methods to control measurement settings in order to efficiently determine model parameters. Given an parametric model - analogous to a fitting function - Bayesian inference uses each measurement 'data point' to refine model parameters. Using this information, the software suggests measurement settings that are likely to efficiently reduce uncertainties. A TCP socket interface allows the software to be used from experimental control software written in other programming languages.

The images and values in this dataset are used to ensure conformance with ISO/IEC 29794-4, which may be purchased from https://www.iso.org/standard/62791.html. Values were computed with NIST's NFIQ 2 software, https://github.com/usnistgov/NFIQ2.

Figures and relevant data from the paper "Broadband Electromagnetic Properties of Engineered Flexible Absorber Materials" are found here . The paper was published on Advanced Materials Technologies in 2023. ABSTRACT: Flexible and stretchable materials have attracted significant interest for applications in wearable electronics and bioengineering fields. Recent developments also incorporate mounted and embedded microwave circuits, components, and systems with engineered flexible materials that operate over a broadband frequency range (~1 to 100 GHz).
