Data for the figures in the manuscript entitled "Compact dual comb time-transfer and ranging for future space-based distributed sensing" published in Applied Optics. Abstract: We describe a general design for a compact frequency comb-based optical time transfer and ranging node with volume of 14 L, mass of 10 kg, and power consumption of 46 W. We assess the residual noise from the comb-based system by making both ranging and time transfer measurements using these compact nodes over a 4.4 km free-space testbed.

This software is a cellular vehicle-to-everything (C-V2X) interoperability analyzer tool developed at the National Institute of Standards and Technology (NIST) Internet of Thing (IoT) Devices Interoperability Testbed. It can be used to automatically analyze and assess C-V2X protocol compatibility and interoperability among commercial on-board units (OBUs) and road-side units (RSUs) based on the IEEE 1609.2, IEEE 1609.3, and SAE J2735 standards to achieve and assure their interoperability.

This repository contains example data and analysis scripts for tension tests of soft elastomer strips with stereo digital image correlation (DIC) for full-field strain on the specimen surface, which is associated with a manuscript describing the technique. Specifically, the material of interest is a liquid crystal elastomer - a polymer consisting of nematic ordering of the polymer chains that leads to unique behaviors associated with time- and history-dependent strain redistribution in the crystalline domains of the material.

This includes source and compiled code for translating SysML models extended by the SysML Extension for Logistics Modeling and Analysis (SysLMA) to logistics analysis platforms, along with library, profile, and example files.

Measurements for experiments presented in the paper "Evaluating Time Occupancy and Time-Scales in Interference Testing with Pulse-Modulated Noise", IEEE Transactions on Electromagnetic. Compatibility, vol. 67, no. 4, pp. 1116-1128, Aug 2025. Data is provided for interference susceptibility experiments with a commercial off-the-shelf (COTS) IEEE 802.11n wireless local area network (WLAN) Wi-Fi link as the victim system. See the README file for further details.

This is a set of scripts to deploy and control 5G network.
It is primarily useful for running an emulated 5G network in Docker Compose environment.

March 2025 Update. Here we provide hourly observations of atmospheric carbon dioxide (CO2), methane (CH4), and (for a few sites) carbon monoxide (CO) from tower-based sites in the NIST Northeast Corridor network. Each *.tgz (tar/gzip) archive contains data files for a given site location, named by its 3-letter code. To extract on a unix platform, use "tar -xvzf <filename>".

This collection of AI models consists of the trained yet unreleased models constructed for the TrojAI program. These models were not required for the published round they come from for some reason. Some were simply extras, others did not meet the release criteria for accuracy or trojan attack success rate, or other reasons. These models should not be considered high quality. They might be poorly trained and unfit for their stated purpose. Examine the metadata released with each model to determine whether you can leverage it.

This repository provides the raw data and analysis code used to demonstrate the implementation of a mathematical framework that uses internal standards to correct for compositionally in MGS datasets. Some of the data contained herein was previously published and is reanalyzed in the context of this new framework, while other datasets represent newly analyzed samples. Please refer to the associated publication for further discussion and a full exploration of the results.
