Environmental impact of manufactured products: A measure inspired by nature

July 10, 2009
Author(s)
Prabir Sarkar, Sudarsan Rachuri, Hyo Won Suh, Kevin W. Lyons, Ram D. Sriram
Environmental impacts of products are generally determined by using criteria or indicators. There are many criteria or indicators available and during design selecting some of them and assigning weight is difficult. As natural systems are considered to be

Manufacturing industry is facing an enormous challenge today in trying to integrate a wide range of systems. The systems span the functional areas of manufacturing, as well as, the multitude of organizations and countries involved in the manufacture of

Economics of Measurement Uncertainty and Tolerances

July 1, 2009
Author(s)
Steven D. Phillips, J.M. Baldwin, William T. Estler
Productivity is considered by considering Cobb-Douglas production function and focusing on total factor productivity (TFP). We argue that developed economies like the United States need to develop TFP by utilizing advances in computation power and insights

Robots to the Rescue

June 30, 2009
Author(s)
Elena R. Messina
Despite current limitations, robots can still play a significant role in helping the response community by being their eyes and ears in dangerous, unknown, or difficult-to-access locations. This article describes how the National Institute of Standards and

OntoSTEP: OWL-DL Ontology for STEP

June 15, 2009
Author(s)
Sylvere Krima, Raphael Barbau, Xenia Fiorentini, Sudarsan Rachuri, sebti foufou, 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

Semantic-Mediation for Standards-based B2B Interoperability

June 15, 2009
Author(s)
Marko Vujasinovic, Nenad Ivezic, Boonserm Kulvatunyou, Edward J. Barkmeyer Jr., Michele Missikoff, Francesco Taglino, Zoran Marjanovic, Igor Miletic
The authors discuss a semantic-mediation architecture to advance traditional approaches for standards-based business-to-business (B2B) interoperability. The architecture is supported by the ATHENA Knowledge Representation and Semantics Mediation tool suite

Service Oriented and Orchestrated Framework for Supply Chain Integration

June 8, 2009
Author(s)
Jack C.P. Cheng, Kincho H. Law, Albert T. Jones, Ram D. Sriram
Supply chain management integrates key business processes and facilities, involving end users and suppliers that provide products, services and information. Supply chain integration can potentially add value to the stakeholders along product development

Test Tool for Industrial Ethernet Network Performance

June 5, 2009
Author(s)
James D. Gilsinn, Freemon Johnson
The number of devices that implement Ethernet interfaces on the factory floor is growing at an exponential rate along with the adoption of industrial-grade Ethernet networks on the plant floor. In addition to the sheer number of devices using industrial

Author(s)
Richard L. Rhorer, Eric P. Whitenton, Timothy J. Burns, Steven P. Mates, Jarred C. Heigel, April L. Cooke, Johannes A. Soons, Robert W. Ivester
NOTE: This is a two-page abstract for publication in the CD-ROM conference proceedings only. Oral presentation of the complete paper will be presented at the conference (SEM, June 1-4, 2009, Albuquerque). This paper discusses recent results of studying Ti

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
