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.

Data from "Flaming Tests on Upholstered Chair Mock-Ups"

Data provided by  National Institute of Standards and Technology

The effectiveness and the failure mechanism of fire barriers in residential upholstered furniture (RUF) were investigated by full-scale flaming tests on single upholstered chair mock-ups. Six fire barriers were tested. The fire barriers were screened for (1) the presence of elements that are typically used in fire retardants and, (2) the presence of targeted fire retardants.

Baseline Deep Learning Detectors for Radar Detection in the 3.5 GHz CBRS Band

Data provided by  National Institute of Standards and Technology

This project aims to create a comprehensive framework for generating radio frequency (RF) datasets, designing deep learning (DL) detectors, and evaluating their detection performance using both simulated and experimental test data. The proposed tools and techniques are developed in the context of dynamic spectrum use for the 3.5 GHz Citizens Broadband Radio Service (CBRS), but they can be utilized and expanded for standardization of machine learned spectrum awareness technologies and methods.

Biospheric CO2 surface flux estimates from the Vegetation Photosynthesis & Respiration Model (VPRM) in the eastern USA and Canada: November 2016 to December 2020

Data provided by  National Institute of Standards and Technology

Monthly zip files from November 2016 to December 2020, with each zip containing hourly .tif files with gridded CO2 fluxes at 0.02 degree resolution in an eastern North American domain from 33 - 47 degrees north and 92 - 67 degrees west. For each hour, there is a file with Ecosystem Respiration fluxes, as well as a file for Gross Ecosystem Exchange during daytime hours only. To derive Net Ecosystem Exchange, respiration and GEE fluxes must be summed. Units are micromoles per m2*s after dividing original data by 1000.

Evaluation of Timers Related to ProSe-based UE-to-Network Relays

Data provided by  National Institute of Standards and Technology

User Equipment (UE)-to-Network Relay functionality was introduced in Release 13 of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) to extend and improve user connectivity. A UE connected to the network (relay UE) provides network access to another UE (remote UE) by establishing a direct one-to-one connection with it using the sidelink (SL) channels over the PC5 interface. The PC5 signaling is used for the establishment and maintenance of this direct connection, and different procedures and timers are linked to these processes.

Trojan Detection Software Challenge - nlp-sentiment-classification-mar2021-test

Data provided by  National Institute of Standards and Technology

Round 5 Test DatasetThis is the test data used to construct and evaluate trojan detection software solutions. This data, generated at NIST, consists of natural language processing (NLP) AIs trained to perform text sentiment classification on English text. A known percentage of these trained AI models have been poisoned with a known trigger which induces incorrect behavior. This data will be used to develop software solutions for detecting which trained AI models have been poisoned via embedded triggers.
