NIST Micronutrients Measurement Quality Assurance Program Winter and Summer 2017 Comparability Studies

Data provided by  National Institute of Standards and Technology

The Micronutrients Measurement Quality Assurance Program (MMQAP) was coordinated by the Chemical Sciences Division and supported measurement technology for selected fat- and water-soluble vitamins and carotenoids in human serum. This program was initiated in 1984 by the National Cancer Institute Division of Cancer Prevention and Control to ensure the long-term reliability of the measurements made while studying the possible cancer chemoprevention roles of these compounds.

Copper k-alpha xray emission spectrum

Data provided by  National Institute of Standards and Technology

This data set consist of two representations of the electron-induced copper k-alpha x-ray emission spectrum. One file contains rebinned counting data, and is close to 'raw'. The second file contains a least-squares spline of the data, which should be a highly useful representation for computational purposes.

Temperature profiles of acrylonitrile butadiene styrene (ABS) during bench-scale material extrusion additive manufacturing

Data provided by  National Institute of Standards and Technology

Temperature profiles of acrylonitrile butadiene styrene (ABS) filament during material extrusion additive manufacturing. Printing temperature and velocities cover the full "printable" range of the ABS filament and are corrected for reflected infrared photons. The profile of the active printing layer and two sub-layers are included. See the associated publication for the full experimental details.

SHARP - Shape Analysis Research Project

Data provided by  National Institute of Standards and Technology

We have applied 3D shape-based retrieval to various disciplines such as computer vision, CAD/CAM, computer graphics, molecular biology and 3D anthropometry. We have organized two workshops on 3D shape retrieval and two shape retrieval contests. We also have developed 3D shape benchmarks, performance evaluation software and prototype 3D retrieval systems. We have developed a robotic map quality assessment tool in collaboration with MEL) We also have developed different shape descriptors to represent 3D human bodies and heads efficiently and other work related to 3D anthropometry.

SHREC'15: Range Scans based 3D Shape Retrieval

Data provided by  National Institute of Standards and Technology

The objective of this shape retrieval contest is to retrieve 3D models those are relevant to a query range scan. This task corresponds to a real life scenario where the query is a 3D range scan of an object acquired from an arbitrary view direction. The algorithm should retrieve the relevant 3D objects from a database.

Task description:
In response to a given set of range scan queries, the task is to evaluate similarity scores with the target models and return an ordered ranked list along with the similarity scores for each query.
