Reusing Metamodels and Notation with Diagram Definition

June 28, 2016
Author(s)
Conrad E. Bock, Maged Elaasar
It is increasingly common for language specifications to separate visual forms (concrete syntax) from underlying concepts (abstract syntax), enabling languages to define multiple visual forms for the same underlying concepts, and for the same visual form

A Snapshot of 118 Solid State Lighting Testing Laboratories' Capabilities

June 23, 2016
Author(s)
C Cameron Miller, Hannah Hasting, Maria Nadal
The National Institute of Standards and Technology (NIST) began to offer proficiency testing for Solid-State Lighting (SSL) products through a Measurement Assurance Program (MAP) in 2010. The MAP program provided proficiency testing complimenting

Strategies for Achieving Measurement Assurance for Cell Therapy Products

June 1, 2016
Author(s)
Carl G. Simon Jr., Anne L. Plant, Sumona Sarkar, John T. Elliott, Sheng Lin-Gibson
Cell therapy products (CTPs) need quantitative, validated, and robust assays to support informed decision making during their development, manufacturing, and regulation. These products, the materials involved in their production and the methods for

Recommendations for Autonomous Industrial Vehicle Performance Standards

May 31, 2016
Author(s)
Roger V. Bostelman
A workshop was held at the IEEE International Conference on Robotics and Automation, called: "Autonomous Industrial Vehicles: From the Laboratory to the Factory Floor." Nine research papers were presented followed by a discussion session summarized in this

Understanding sustainability data through unit manufacturing process representations: a case study on stone production

May 24, 2016
Author(s)
Bjoern J. Johansson, Mahesh Mani, William Z. Bernstein, Kevin W. Lyons, KC Morris, Laurie Rebouillat, Ilaria Barletta
Efficiency of natural stone production processes in quarries directly affects the economic output and environmental performances, such as production lead times and energy consumptions. Knowledge on stone production processes is crucial in making

Aaron N. Johnson, Rodney A. Bryant, Tamae M. Wong, James R. Whetstone, Eric Harman, Woong Kang, Keith A. Gillis, Hsin-Hung Lee, Iosif I. Shinder, Liang Zhang
On April 20-21, 2015, NIST hosted a workshop that, through measurement science, enabled the owners of stationary sources (primarily the electric power industry) and their regulatory agencies (federal and state) to better characterize greenhouse gas (GHG)

ASTM Workshop on Standards & Measurements for Tissue Engineering Scaffolds

January 1, 2016
Author(s)
Carl G. Simon Jr., John Test, Michael Yaszemski, Reto Luginbuehl, Anthony Ratcliffe, Paul Tomlins
A “Workshop on Standards & Measurements for Tissue Engineering Scaffolds” was held on May 21, 2013 and was sponsored by the American Society of Testing and Materials International (ASTM International) in Indianapolis, IN. The purpose of the workshop was to

A defect-driven diagnostic method for machine tool spindles

December 31, 2015
Author(s)
Gregory W. Vogl, M A. Donmez
Simple vibration-based metrics are, in many cases, insufficient to diagnose machine tool spindle condition. These metrics couple defect-based motion with spindle dynamics; diagnostics should be defect-driven. A new method and spindle condition estimation
