We present the data supporting "Experimental test of the intrinsic dimensionality of Hounsfield unit measurements" (In preparation). In this study, we passed 34 different substances in separate vials through a computed tomography (CT) scanner at 4 different voltages. At each voltage, we obtained 1824 images (in DICOM format) depicting a sequence of slices through the vials. All 7296 images are provided here.

These measurements were performed as part of the 2018 Additive Manufacturing Benchmark Test Series (AM-Bench), specifically supporting the melt pool geometry challenge (CHAL-AMB2018-02-MP) and cooling rate challenge (CHAL-AMB2018-02-CR).

The PerfLoc Prize Competition (https://perfloc.nist.gov) was developed by NIST during 2015-2017 and was run during 2017-2018. The Competition was concluded with a single winner on May 16, 2018. However, NIST believes the data collected for the PerfLoc Competition is still of value to the R&D community, because there is still room to develop better signal processing and data fusion algorithms that would fuse various types of smartphone data collected in this project to develop indoor localization apps with higher localization accuracy.

Polymer Reference Interaction Site Model (PRISM) theory describes the equilibrium spatial-correlations of liquid-like polymer systems including melts, blends, solutions, block copolymers, ionomers, liquid crystal forming polymers and nanocomposites. Using PRISM theory, one can calculate thermodynamic (e.g., second virial coefficients, Flory-Huggins interaction parameters, potentials of mean force) and structural (eg., pair correlation functions, structure factors) information for these macromolecular materials.

A method was developed to reduce the point-based registration error by restoring the rigid body condition (RRBC method). Registration is the process of transforming one coordinate frame to another coordinate frame. The coordinate frame from which points are transformed is called the working frame and the coordinate frame to which points are transformed is called the destination frame. The RRBC method can be used to reduce the uncertainty of a hole location and thus, improve the success rate for insertion tasks.

The translator implements the SysML Extension for Physical Interaction and Signal Flow Simulation (SysPhS). It can generate Modelica or Simulink/Simscape files from SysML models extended according to the SysPhS specification. This dataset binary and source code for the translator, as well as a set of SysML models that can be translated into simulation models. Disclaimer: Certain commercial equipment, instruments, or materials are identified in this dataset to specify the experimental procedure adequately.

An in-house developed finite-difference time-domain (FDTD) code has been used to simulate certain patterned defects as found in the semiconductor industry. Intrinsic to FDTD is the establishment of a simulation domain, a 3-D matrix of some arbitrary size (X, Y, Z) comprised of smaller cells (in our case, cubic with side length x), with each cell indexed to a material (including the vacuum) to form the geometry.

County Business Patterns (CBP) is an annual series that provides sub-national economic data by industry. This series includes the number of establishments, employment during the week of March 12, first quarter payroll, and annual payroll. This data is useful for studying the economic activity of small areas, analyzing economic changes over time, and as a benchmark for other statistical series, surveys, and databases between economic censuses.
