Synthetic Temperature Data for Predicting Flashover Occurrence Using Surrogate Temperature Data

Data provided by  National Institute of Standards and Technology

This data set provides heat detector temperatures in a single-story ranch structure with a living room, kitchen, dining room, and three bedrooms. 20000 sets of detector temperatures are generated using CData [1]. The data set are obtained based on simulation runs with various fire conditions and door opening conditions. The fire is described based on t-squared law. The peak heat release rate and time to peak range from approximately 1667 kW to 4620 kW and from 210 s to 1540 s, respectively. A detailed description of this work can be found in Ref.

Dataset for Absorbance Microscopy for Quantitative and Traceable Trypan Blue Cell Viability Measurement

Data provided by  National Institute of Standards and Technology

The use of the microscope to assess cell viability is an inherently qualitative and subjective process. This project demonstrates a new absorbance microscopy modality for quantitative single-cell assessment of cell viability via trypan blue staining. This dataset consists of .tif images of live and dead stained and unstained Jurkat cells as well as the numerical data related to the corresponding journal article. The images were collected via brightfield microscopy through a 610nm bandpass filter.

Trojan Detection Software Challenge - image-classification-feb2021-test

Data provided by  National Institute of Standards and Technology

Round 4 Test DatasetThe data being generated and disseminated is the test data used to construct trojan detection software solutions. This data, generated at NIST, consists of human level AIs trained to perform image classification. 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.

Preliminary U.S. Space Economy Data

Data provided by  Bureau of Economic Analysis

BEA has developed a preliminary set of statistics measuring the contributions of space-related industries to the overall U.S. economy.These estimates give business leaders, policymakers, and the public a new tool to analyze the space economy and to inform investment decisions.Preliminary estimates of the U.S. space economy's GDP, gross output, private employment, and private compensation by industry were published in the December 2020 Survey of Current Business.
