Measurement and Processed Data From A Graph Database Approach to Wireless IIoT Work-cell Performance Evaluation
Data provided by National Institute of Standards and Technology
The work-cell is an essential industrial environment for testing wireless communication techniques in factory automation processes. A graph database approach to storing and analyzing network performance data from a manufacturing factory work-cell is introduced. A robotic testbed performs a pick-and-place task using two collaborative grade robot arms, machine emulators, and wireless communication devices. A graph database is implemented to capture network data and operational event data among the actors within the testbed.

Regional Price Parities by State and Metro Area
Data provided by Bureau of Economic Analysis
Regional Price Parities allow comparisons of buying power across the 50 states and the District of Columbia, or from one metro area to another, for a given year. Price levels are expressed as a percentage of the overall national level.

GAA-GAA Coexistence in the CBRS Band: Performance Evaluation of Approach 3
Data provided by National Institute of Standards and Technology
The General Authorized Access (GAA) users in the Citizens Broadband Radio Service (CBRS) band are the lowest priority users. They must cooperate with each other to minimize mutual interference and increase spectrum utilization. The Wireless Innovation Forum (WInnForum), a standardization body, has recommended three schemes to address this GAA-GAA coexistence issue. This dataset contains the performance data obtained from simulation experiments run to evaluate the performance of the WInnForum scheme called "Approach 3".

Process Monitoring Dataset from the Additive Manufacturing Metrology Testbed (AMMT): Overhang Part X4
Data provided by National Institute of Standards and Technology
This dataset includes files from the experiment titled 'OverhangPartX4' pertaining to a three-dimensional (3D) additive manufacturing (AM) build performed on the Additive Manufacturing Metrology Testbed (AMMT) by Ho Yeung and Brandon Lane on June 28, 2019. The files include the input command files, materials data, in-situ process monitoring data, and metadata. This data is one of a set of 'AMMT Process Monitoring Datasets', as part of the Metrology for Real-Time Monitoring of Additive Manufacturing project at the National Institute of Standards and Technology (NIST).

Optical Modeling of Single Asian Dust and Marine Air Particles: A Comparison with Geometric Particle Shapes for Remote Sensing
Data provided by National Institute of Standards and Technology
The project that produced these data involved the analysis and modeling of atmospheric Asian dust particles and background marine air particles collected in Hawaii, USA at the Mauna Loa Observatory (MLO) of the National Oceanic and Atmospheric Administration. Individual heterogeneous dust particles were analyzed with focused ion-beam scanning electron microscopy and energy-dispersive X-ray spectroscopy.

REFLEAK: NIST Leak/Recharge Simulation Program for Refrigerant Blends - SRD 73
Data provided by National Institute of Standards and Technology
REFLEAK estimates composition changes of zeotropic mixtures in leak and recharge processes. The leak/recharge simulation program consists of three parts: 1) the pre-processing section for inputting required data, 2) the computation section which simulates leak/recharge processes and, 3) the post-processing section to display calculated results and to print or store data and graphs.

Simulated Radar Waveform and RF Dataset Generator for Incumbent Signals in the 3.5 GHz CBRS Band
Data provided by National Institute of Standards and Technology
This software tool generates simulated radar signals and creates RF datasets. The datasets can be used to develop and test detection algorithms by utilizing machine learning/deep learning techniques for the 3.5 GHz Citizens Broadband Radio Service (CBRS) or similar bands. In these bands, the primary users of the band are federal incumbent radar systems. The software tool generates radar waveforms and randomizes the radar waveform parameters.
