Almanac API - Ranking by Geography Type within the Nation

Data provided by  National Telecommunications and Information Administration

This API is designed to find the rankings by any geography type within the nation with a specific census metric (population or household) and ranking metric (any of the metrics from provider, demographic, technology or speed). Support for full list of rankings by nation is not allowed for geography types (e.g., county, census place, usf) so only the top ten and bottom ten rankings would be returned through the API.

Broadband Summary API - By Geography Type and Geography ID

Data provided by  National Telecommunications and Information Administration

This API returns broadband summary data by geography IDs for a specific geography type. It is designed to retrieve broadband summary data by geography and census metrics (population or households) combined as search criteria. The data includes wireline and wireless providers, different technologies and broadband speeds reported in the particular area being searched for on a scale of 0 to 1.

Broadband Summary API - Nation

Data provided by  National Telecommunications and Information Administration

This API returns broadband summary data for the entire United States. It is designed to retrieve broadband summary data and census metrics (population or households) combined as search criteria. The data includes wireline and wireless providers, different technologies and broadband speeds reported in the particular area being searched for on a scale of 0 to 1.

Ballistic test results for several different soft body armor systems

Data provided by  National Institute of Standards and Technology

The performance standard for ballistic-resistant body armor published by the National Institute of Justice (NIJ), NIJ Standard 0101.06, recommends estimating the perforation performance of body armor by performing a statistical analysis on V50 ballistic limit testing data. The first objective of this study is to evaluate and compare the estimations of the performance provided by different statistical methods applied to ballistic data generated in the laboratory.

SHREC'11 Track: Shape Retrieval on Non-rigid 3D Watertight Meshes

Data provided by  National Institute of Standards and Technology

Non-rigid 3D objects are commonly seen in our surroundings. However, previous efforts have been mainly devoted to the retrieval of rigid 3D models, and thus comparing non-rigid 3D shapes is still a challenging problem in content-based 3D object retrieval. Therefore, we organize this track to promote the development of non-rigid 3D shape retrieval.
The objective of this track is to evaluate the performance of 3D shape retrieval approaches on a large-scale database of non-rigid 3D watertight meshes generated by our group.

NIST Electron Effective-Attenuation-Length Database - SRD 82

Data provided by  National Institute of Standards and Technology

The NIST Electron Effective Attenuation Length Database provides values of electron effective attenuation lengths (EALs) in materials at user-selected electron energies between 50 eV and 2,000 eV. The database was designed mainly to provide EALs (to account for effects of elastic-electron scattering) for measurements of the thicknesses of overlayer films and, to a much lesser extent, for measurements of the depths of thin marker layers. EALs are calculated using an algorithm based on electron transport theory for measurement conditions specified by the user.

Guide to Available Mathematical Software

Data provided by  National Institute of Standards and Technology

The Guide to Available Mathematical Software (GAMS) is a virtual repository of software for solving frequently occurring mathematical problems such as the linear systems of equations, differential equations and evaluation of special functions. Access to the database is provided through a web interface in which software can be identified through a problem classification scheme or by name.

NIST Electron Inelastic-Mean-Free-Path Database - SRD 71

Data provided by  National Institute of Standards and Technology

The NIST Electron Inelastic-Mean-Free-Path Database provides values of electron inelastic mean free paths (IMFPs) principally for use in surface analysis by Auger-electron spectroscopy and X-ray photoelectron spectroscopy. The database includes IMFPs calculated from experimental optical data and IMFPs measured by elastic-peak electron spectroscopy. If no calculated or measured IMFPs are available for a material of interest, values can be estimated from the predictive IMFP formulae of Tanuma et al. and of Gries.
