Methods for transferring the SI unit of force from millinewtons to piconewtons

June 1, 2009
Author(s)
Gordon A. Shaw, Koo-Hyun Chung, Douglas T. Smith, Jon R. Pratt
The establishment of standards for small force measurement requires a link to an absolute measurement of force traceable to the international system of units (SI). To this end, a host of different means are being employed by the NIST small force

Standardization Activities for Solid State Lighting in the USA

May 29, 2009
Author(s)
Yoshihiro Ohno
In support of the U.S. Department Energy s Energy Star program for solid state lighting, a series of standards for solid state lighting products have been developed in the USA. The standards published related to measurement and color include ANSI-NEMA

PARAMETER VALIDATION USING CONSTRAINT OPTIMIZATION FOR MODELING AND SIMULATION

May 11, 2009
Author(s)
Guodong Shao, Charles R. McLean, Alexander Brodsky, Paul Ammann
Modeling and simulation (M&S) techniques are increasingly being used to solve problems and aid decision making in many different fields. Results of simulations are expected to provide reliable information for decision makers. But potential errors may be

OntoSTEP: OWL-DL Ontology for STEP

May 4, 2009
Author(s)
Sylvere Krima, Raphael Barbau, Xenia Fiorentini, Sudarsan Rachuri, Ram D. Sriram
The Standard for the Exchange of Product model data (STEP) [1] contains product information mainly related to geometry. The modeling language used to develop this standard, EXPRESS, does not have logical formalism that will enable rigorous semantics. In

Advancing Manufacturing Research Through Competitions

April 17, 2009
Author(s)
Stephen B. Balakirsky, Rajmohan Madhavan
Competitions provide a technique for building interest and collaboration in targeted research areas. This paper will present a new competition that aims to increase collaboration amongst Universities, automation end-users, and automation manufacturers

Use of Semantic Mediation in Manufacturing Supply Chains

April 6, 2009
Author(s)
Peter O. Denno, Edward J. Barkmeyer Jr., Fabian M. Neuhaus
This case discusses lessons learned about enabling interoperability using semantic methods in three automotive industry projects spanning 8 years. In each project, the essential form of the solution is to reconcile differences in viewpoint of entities

Understanding Imaging and Metrology with the Helium Ion Microscope

March 1, 2009
Author(s)
Michael T. Postek, Andras Vladar, Bin Ming
The development of accurate metrology for the characterization of nanomaterials is one barrier to innovation confronting all phases of nanotechnology. Ultra-high resolution microscopy is a key technology needed to achieve this goal. But, current microscope
