Simulated X-ray computed tomography (XCT) and ground truth images of cylindrical sample with randomly distributed spherical pores

Data provided by  National Institute of Standards and Technology

X-ray computed tomography (XCT) datasets with known ground truth pores were developed using realistic XCT simulation. Non-overlapping spherical pores of varying sizes are randomly distributed in a cylindrical part near surfaces and within the core. Ground truth data, ground truth binary data, and reconstructed data for three different signal-to-noise ratios (SNRs) are provided. The data set can be used for evaluation and comparison of image segmentation/detection algorithms.

Maxwell-Bloch Equations for Two-Level System

Data provided by  National Institute of Standards and Technology

The Maxwell-Bloch equations for a two-level system are solved in a particular case. The example follows that of P. Siddons, "Light propagation through atomic vapours," Journal of Physics B: Atomic, Molecular, and Optical Physics 47, 093001 (2014). In the reference, the optical intensity, population of the upper state and coherence are given for light with a carrier frequency which is on resonance. Here, the same example is worked, but the result is given at intermediate times as well as at the entrance and exit faces as in the example.

Data to Support the Development of Rapid GC-MS Methods for Seized Drug Analysis

Data provided by  National Institute of Standards and Technology

This dataset contains raw datafiles that support the development of rapid gas chromatography mass spectrometry (GC-MS) methods for seized drug analysis. Files are provided in the native ".D" format collected from an Agilent GC-MS system. Files can be opened using Agilent proprietary software or freely available software such as AMDIS (which can be downloaded at chemdata.nist.gov). Included here is data of seized drug mixtures and adjudicated case samples that were analyzed as part of the method development process for rapid GC-MS.
