Tool for Evaluation of Vaporized Hydrogen Peroxide Disinfection of N95 Masks in Rooms
Data provided by National Institute of Standards and Technology
The SARS-CoV-2 virus has put a strain on the supply and distribution of N95 masks, with some hospitals electing to reuse masks after disinfection. Currently, vaporized hydrogen peroxide (VHP) mask disinfection systems are being deployed at multiple locations throughout the United States, for example in shipping containers and in small rooms. Such enclosures will be of a different size, have different surface materials and have varying air change rates; all these parameters will impact the VHP dose that the masks receive.

Data for "Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability"
Data provided by National Institute of Standards and Technology
This data was used for main results for the paper entitled "Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability".
We could calculate relative phase fluctuation and Allan deviation for both Yb optical clocks and 10 GHz microwaves. Uncertainty of our down-conversion system was also calculated from this.

SysML Model Libraries Supporting Discrete Event Logistics Systems (DELS) Models
Data provided by National Institute of Standards and Technology
System models and model-based engineering methods have the promise of transforming the way that industrial engineers interact with production and logistics systems. Model-based methods play a role in improving communication between stakeholders, interoperability between systems, automated access to consistent analysis models, and multi-disciplinary design methods for complex systems.

Optimal Bayesian Experimental Design Version 1.0.1
Data provided by National Institute of Standards and Technology
Python module 'optbayesexpt' uses optimal Bayesian experimental design methods to control measurement settings in order to efficiently determine model parameters. Given an parametric model - analogous to a fitting function - Bayesian inference uses each measurement 'data point' to refine model parameters. Using this information, the software suggests measurement settings that are likely to efficiently reduce uncertainties. A TCP socket interface allows the software to be used from experimental control software written in other programming languages.

Synthetic Temperature Data for P-Flash - A Machine Learning-Based Model for Flashover Prediction Using Recovered Temperature Data
Data provided by National Institute of Standards and Technology
This data set provides heat detector temperatures in a single story three-compartment structure. 1000 sets of detector temperatures are generated using CData [1]. The data set are obtained based on simulation runs with various t-squared fires. The peak heat release rate and time to peak range from approximately 50 kW to 2200 kW and from 50 s to 1400 s, respectively. A detailed description of this work can be found in Ref. [2].

NIST Soft MUD: A reference implementation of a Manufacturer's Usage Description (MUD) manager using Software Defined Networking (SDN).
Data provided by National Institute of Standards and Technology
The goal of the MUD (Manufacturer Usage Description) specification is to provide a means for manufacturers of Things to indicate what sort of access and network functionality they require for the Thing to properly function. A manufacturer associates a MUD file with a device which specifies an ACL for the device to within deployment specific parameters. The MUD standard is defined in RFC 8520 This repository publishes a public domain scalable implementation of the IETF MUD standard. MUD is implemented on SDN capable switches using OpenDaylight as the SDN controller.

Trojan Detection Software Challenge - image-classification-jun2020-train
Data provided by National Institute of Standards and Technology
Round 1 Training DatasetThe data being generated and disseminated is the training data used to construct trojan detection software solutions. This data, generated at NIST, consists of human level AIs trained to perform a variety of tasks (image classification, natural language processing, etc.). 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.
