Author(s)
Charles R. McLean, Yung-Tsun Lee, Sanjay Jain, Charles W. Hutchings
The purpose of this document is to provide: 1) a compendium of information pertaining to incident management modeling and simulation, and 2) a foundation for the establishment of a modeling and simulation technical interest group whose focus is information

A Decision-Guided Energy Management Framework for Sustainable Manufacturing

August 31, 2011
Author(s)
Guodong Shao, Alexander Brodsky, Jorge Arinez , Daniel A. Menasce , Paul Ammann
A growing number of manufacturing industries are initiating efforts to address sustainability issues. According to the National Association of Manufacturers, the manufacturing sector currently accounts for about one third of all energy consumed in the

Integration of Life Cycle Inventories Incorporating Manufacturing Unit Processes

August 31, 2011
Author(s)
Mark B. Campanelli, Jonatan K. Berglund, Sudarsan Rachuri
Sustainable manufacturing (SM) concerns the manufacture of products with regard to environmental, social, and economic impacts over the entire life cycle. With a primary focus on environmental concerns, life cycle assessment (LCA) can support SM practices

TOWARDS INDUSTRIAL IMPLEMENTATION OF EMERGING SEMANTIC TECHNOLOGIES

August 31, 2011
Author(s)
Paul W. Witherell
In this paper, we identify five main obstacles in the development of an industry-ready application of semantic knowledge management systems and discuss how each of these challenges can be addressed. These obstacles include the ease of new knowledge

A Prototype IEEE 1451.4 Smart Transducer Interface for Sensors and Actuators

August 19, 2011
Author(s)
Yuyin Song, David M. Westbrook, Kang B. Lee
Analog transducers (sensors or actuators) are widely used in industry. The Institute of Electrical and Electronics Engineers (IEEE) 1451.4 standard defines a mixed-mode communication protocol and the Transducer Electronic Data Sheet (TEDS) formats for

GaN Nanowires Grown by Molecular Beam Epitaxy

August 1, 2011
Author(s)
Kristine A. Bertness, Norman A. Sanford, Albert Davydov
The unique properties of GaN nanowires grown by molecular beam epitaxy are reviewed. These properties include the absence of residual strain, exclusion of most extended defects, long photoluminescence lifetime, low surface recombination velocity,and high

Large-Area Overhead Manipulator for Access of Fields

July 22, 2011
Author(s)
Jeffrey W. White, Roger V. Bostelman
Multi-axis, cable-driven manipulators have evolved over many years providing large area suspended platform access, programmability, relatively rigid and flexibly- positioned platform control and full six degree of freedom (DOF) manipulation of sensors and
