STEP File Analyzer and Viewer Software

Data provided by  National Institute of Standards and Technology

The STEP File Analyzer and Viewer is a software tool that generates a spreadsheet or a set of CSV (comma-separated value) files from a STEP (ISO 10303 Standard for Exchange of Product model data) Part 21 file. STEP files are used to represent product and manufacturing information (PMI) and for data exchange and interoperability between Computer-Aided Design (CAD), Manufacturing (CAM), Analysis (CAE), and Inspection (CMM) software related to the smart manufacturing digital thread. STEP is also used for the long-term archiving and retrieval of product data.

BGP Secure Routing Extension (BGP-SRx): Reference Implementation and Test Tools for Emerging BGP Security Standards

Data provided by  National Institute of Standards and Technology

The NIST BGP Secure Routing Extension (BGP-SRx) prototype is an open source reference implementation and research platform for investigating emerging BGP security extensions and supporting protocols such as RPKI Origin Validation and BGPSec Path Validation. BGP-SRx is designed in such to minimize the dependencies on and the impact on specific router implementations. As a result, much functionality is provided by the stand-alone SRx server module. The prototype is also designed to support experimentation with various deployment architectures.

Deterministic Move Lists for Federal Incumbent Protection in the CBRS Band

Data provided by  National Institute of Standards and Technology

The 3.5 GHz citizens broadband radio service (CBRS) band in the U.S. is a key portion of mid-band spectrum shared between commercial operators and existing federal and non-federal incumbents. To protect the federal incumbents from harmful interference, a spectrum access system (SAS) is required to use a common, standardized algorithm, called the move list algorithm, to suspend transmissions of some CBRS devices (CBSDs) on channels in which the incumbent becomes active.

NIST-LANL Lanthanide/Actinide Opacity Database

Data provided by  National Institute of Standards and Technology

The database contains radiative line-binned opacities for lanthanides (atomic number 57<=Z<=70) and actinides (atomic number 89<=Z<=102) which are of paramount importance for simulation of light curves and spectra produced by kilonovae. The opacities were calculated by the LANL group under the assumption of local thermodynamic equilibrium. The temperature grid cover the range from 0.01 eV to 5.0 eV while the mass density grid covers 16 orders of magnitude. The database provide search and selection tools along with graphical and tabular outputs.

2021 MML Accolades Program

Data provided by  National Institute of Standards and Technology

The MML Accolades Program has been created to recognize exemplary work by staff, associates, and external collaborators in areas of strategic interest and benefit to MML (The Material Measurement Laboratory, an organization within NIST). With peer nominations from MML employees and associates, Accolades focus on the impact of accomplishments and outcomes of the work of individuals or teams working in or with MML. The MML Accolades program started in 2015. This dataset includes a website with all the past winners since the program's inception.

Simulating Photon Echoes for Quantum Memory

Data provided by  National Institute of Standards and Technology

A Wolfram Demonstration Template has been specialized to a model of a semiclassical model of photon echoes. An incident Gaussian pulse propagates through a material with a dielectric function in the form of a model Atomic Frequency Comb. The output pulse is calculated for seven values of the finesse of the comb.
