Linear Axis Testbed - Rail Degradation Experiment 01

Gregory Vogl, Brian Weiss, M Donmez & Michael Sharp
In this study, a rail of a linear axis testbed was intentionally degraded to various levels, affecting the carriage motion, which can be deduced with either an inertial measurement unit (IMU) or a laser- based reference system. The rail was degraded over a 10-cm-long region. Thus, the two trucks that move on the rail interact with this region of the rail, changing the translational and angular error motions of the carriage. To mechanically simulate spalling,...

LTE Device-to-Device Out-of-Coverage Communication with Frequency Hopping Resource Scheduling Performance Metrics Evaluation Data

Fernando Cintron
This dataset represents the results from conducted simulations to evaluate the performance of Device-to-Device (D2D) communications in LTE when the User Equipment (UEs) are operating in UE-scheduled mode (Mode 2) with frequency hopping enabled. Different scenarios were simulated and communication performance was evaluated for each frequency hopping scheme defined in the LTE standard. The communication performance metrics include the successful transmission- reception ratio of transport blocks (TBs) at the physical layer, and the probability mass...

NIST Machine-Print Database of Gray Scale and Binary Images (MPDB)

Michael D. Garris
This database has been discontinued and is no longer available. The NIST machine-printed database which was formerly part of the Special Databases collection contained gray scale and binary images of machine printed pages. The database was previously known as Special Database 8.

SRM 1632e Trace Elements in Coal (Bituminous)

Thomas W. Vetter
SRM 1632e Trace Elements in Coal (Bituminous) - This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques used in the analysis of coals and materials of a similar matrix.

A suite of atomic structure codes originally developed by R. D. Cowan adapted for Windows-based personal computers.

Alexander Kramida
The package consists of a set of computer programs for calculation of energy levels, radiative transition wavelengths and probabilities, electron impact excitation and photoionization cross sections, etc. The programs were originally written by Robert D. Cowan in 1962-1991 (see R.D. Cowan, The theory of atomic structure and spectra, University of California Press, Berkeley - Los Angeles - London, 1981).

Simple Knowledge Organization System (SKOS) version of Materials Data Vocabulary

Andrea Medina-Smith, Chandler Becker & Kimberly Tryka
A version of the Materials Data Vocabulary structured as Simple Knowledge Organization System (SKOS). The XML was originally created by the TemaTres software. This vocabulary describes the applicability to material science of records in the NIST Materials Resource Registry (NMRR - https://materials.registry.nist.gov/). The NMRR allows for the registration of materials resources, bridging the gap between existing resources and the end users. The NMRR functions as a node in a federated system, making the registered information...

mumpcepy: A Python implementation of the Method of Uncertainty Minimization using Polynomial Chaos Expansions

David Sheen
The Method of Uncertainty Minimization using Polynomial Chaos Expansions (MUM-PCE) was developed as a software tool to constrain physical models against experimental measurements. These models contain parameters that cannot be easily determined from first principles and so must be measured, and some which cannot even be easily measured. In such cases, the models are validated and tuned against a set of global experiments which may depend on the underlying physical parameters in a complex way....

Recommended Gas Phase Enthalpies of Formation for Hydrogen-Oxygen (HxOy) Species

Donald Burgess & Donald R Burgess
Datasets in digital electronic formats are provided for data contained in the publication "Recommended Values for the Gas Phase Enthalpies of Formation of Hydrogen-Oxygen Species;" J. Res. Natl. Inst. Stand. Technol. 121, 108-138 (2016); DOI: 10.6028/jres.121.005.In this work, we compiled gas phase enthalpies of formation for nine hydrogen-oxygen species (HxOy) and selected values for use. The compilation consists of values derived from experimental measurements, quantum chemical calculations, and evaluations. This work updates the recommended values...

Sensor Placement and Detection Coverage for Spectrum Sharing in the 3.5 GHz Band Data

Mudumbai Ranganathan, Anirudha Sahoo, Timothy Hall & Thao Nguyen
This dataset contains the results of simulated deployments of Environmental Sensing Capability (ESC) sensors along the coasts of the contiguous United States in the 3.5 GHz band. The Federal Communications Commission rules for spectrum sharing operation in this band require the ESC sensors to detect the presence of a federal incumbent shipborne radar for interference protection. The results include sensor locations, detection coverage, probability of outage, and probability of false alarm for each Dynamic Protection...

Taxonomy for NIST Website

Katherine Sharpless
This is the taxonomy that is used for classifying information on the NIST website. It comprises a set of top-level designations that include the research areas within NIST, with two levels of subcategories beneath.

Information for the Benchmark1 problems


Richard Ricker
Corrosion is defined as the deterioration of a material due to chemical reactions with its environment. Understanding corrosion, and corrosion rates, is necessary to ensure that the design of objects we interact with every day, from the bridges we drive over to the containers used to transport chemicals, from the pipes that carry our water to the utensils we cook with, are safe and perform to specifications.The Corr-Data dataset was created by the staff of...

Election Results Reporting XML Schema Version 1.0

John Wack, Richard Rivello, Sarah Whitt, Sam Dana, Kim Brace, John Dziurlaj, Don Rehill, Herb Deutsch & Ian Piper
This dataset consists of the XML schema for the NIST 1500-100 Election Results Reporting Common Data Format Specification Version 1.0.

Supplementary data for "Distributions of fitness effects for amino acid changes from high-throughout mutagenesis experiments" (McCandlish and Stoltzfus, 2018)

Arlin B. Stoltzfus
McCandlish and Stoltzfus gathered data from deep mutational scanning experiments on 12 proteins, comprising 56641 distinct amino acid replacement mutations. By converting fitnesses to within-study quantiles, they combined results from all studies to draw general conclusions about distributions of fitness effects for the 380 different types of possible amino acid changes in proteins. They found that most replacements are neither conservative nor radical, but barely different from the background distribution. The shapes of these distributions...

Quantum dot data for machine learning

Justyna Zwolak, Xingyao Wu, Shephen Ragole, Sandesh Kalantre & Jacob Taylor
Using a modified Thomas-Fermi approximation, we model a reference semiconductor system comprising a quasi-1D nanowire with a series of five depletion gates whose voltages determine the number of dots and the charges on each of those dots, as well as the conductance through the wire. The data set consists of 1001 generated gate configurations averaging over different realizations of the same type of device. Each sample data is then stored as a 100x100 pixel map...
