This dataset includes the files pertaining to a 3D additive manufacturing experiment performed on the Additive Manufacturing Metrology Testbed (AMMT) by Ho Yeung on July 11, 2019. The experiment included 55 separate laser scanned 'pads' created on a bare-metal plate. Each pad corresponds to a different laser processing setting, described in the paper Yeung et al. 2020 (https://doi.org/10.1016/j.mfglet.2020.07.005).

NIST Fingerprint Image Quality (NFIQ) 2 is open source software that links image quality of optical and ink 500 PPI fingerprints to operational recognition performance. This allows quality values to be tightly defined and then numerically calibrated, which in turn allows for the standardization needed to support a worldwide deployment of fingerprint sensors with universally interpretable image qualities.

NIST has created a Test System to measure conformance of Computer-Aided Design (CAD) software to American Society of Mechanical Engineers (ASME) standards for Product and Manufacturing Information (PMI), specifically geometric dimensioning and tolerancing (GD&T) information. The test system includes: test case definitions (2D CAD drawings with PMI), CAD models generated from the test cases, STEP files generated from the CAD models, and verification and validation reports.

These v3.0 stratification BED files from the Global Alliance for Genomic Health (GA4GH) Benchmarking Team, the Genome in a Bottle Consortium and the Telomere-to-Telomere Consortium are intended as a standard resource of BED files for use in stratifying true positive, false positive, and false negative variant calls in challenging and targeted regions of the the genome. v3.0 stratifications contain new and revised stratification files and replace v2.0 stratifications.

This dataset is a supplement to the paper titled "Fiber Orientation Angle Effects in Machining of Unidirectional CFRP Laminated Composites" (https://doi.org/10.1016/j.jmapro.2014.06.001). High speed videography of eight cutting tests were performed to study how cutting angle effects cutting force and workpiece surface finish. A description of the experimental setup, as well as a discussion of results, are given in the paper.

Supporting scripts and datasets for Gourdji et al, JGR-B, 2021: "A modified Vegetation Photosynthesis and Respiration Model (VPRM) for the eastern USA and Canada, evaluated with comparison to atmospheric observations and other biospheric models"

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.

We have become aware of errors in the inlet heights at multiple sites and have corrected these in the newest version.

The Nuclear Magnetic Resonance Spectral Measurement Database (NMR-SMDB) was developed for the purpose of organizing and searching NMR spectral data of protein therapeutics, linking spectra to corresponding sample information and enabling quick access to full datasets and entire studies. In addition to supporting internal NIST research, the system could facilitate data access to stakeholders outside of NIST, and future versions of the database software itself could be installed by others for their own data storage and retrieval.
