Componentization in the Systems Modeling Language

November 20, 2013
Author(s)
Conrad E. Bock
This paper describes new capabilities in the Systems Modeling Language that reduce the complexity of specifying systems through componentization, and increase the range of systems that can be specified. Modelers can identify portions of components

Model Based Enterprise Summit Report

November 4, 2013
Author(s)
Joshua Lubell, Simon P. Frechette, Robert R. Lipman, Frederick M. Proctor, John A. Horst, Mark G. Carlisle, Paul J. Huang
This report summarizes the presentations, discussions, and recommendations from the Model-Based Enterprise Summit held at the National Institute of Standards and Technology in December of 2012. The purpose of the Summit was to identify challenges, research

A Literature Review of Sensor Ontologies for Manufacturing Applications

October 23, 2013
Author(s)
Craig I. Schlenoff, Tsai Hong Hong, Roger D. Eastman
The purpose of this paper is to review existing sensor and sensor network ontologies to understand whether they can be reused as a basis for a manufacturing perception sensor ontology, or if the existing ontologies hold lessons for the development of a new

Use Case Analysis for Standard Manufacturing Service Capability Model

September 12, 2013
Author(s)
Yunsu Lee, Boonserm Kulvatunyou, Marko Vujasinovic, Nenad Ivezic
To efficiently assemble manufacturing supply chains, manufacturers need to provide precise and easily accessible their manufacturing service capability (MSC) information described in the form of MSC descriptions. However, a number of challenges exist in

Time-resolved surface infrared spectroscopy during atomic layer deposition

September 10, 2013
Author(s)
Brent A. Sperling, John J. Hoang, William A. Kimes, James E. Maslar
This work presents a novel method for obtaining surface infrared spectra with sub-second time resolution during atomic layer deposition (ALD). Using a rapid-scan Fourier transform infrared (FT-IR) spectrometer, we obtain a series of interferograms (120 ms)

Model Based Enterprise Technical Data Package Requirements

August 20, 2013
Author(s)
Simon P. Frechette, Paul J. Huang
The Department of Defense and the National Institute of Standards and Technology held a Model Based Enterprise Summit and Technical Data Package (TDP) Workshop December 15-17, 2009 in Gaithersburg, MD. The TDP workshop gathered subject matter experts to

Multicomponent Chemical Imaging of Pharmaceutical Solid Dosage Forms with Broadband CARS Microscopy

July 15, 2013
Author(s)
Christopher M. Hartshorn, Marcus T. Cicerone, Young J. Lee, Charles H. Camp, John M. Heddleston, Patrick Marsac, Tim Rhodes, Zhen Liu, Nicole Canfield
We compare broadband coherent anti-Stokes Raman scattering (BCARS) microscopy with spontaneous Raman microscopy for quantitative and qualitative assessment of multicomponent pharmaceuticals. Indomethacin was used as a model active pharmaceutical ingredient

Toward a reference architecture for archival systems

July 10, 2013
Author(s)
Raphael Barbau, Joshua Lubell, Sudarsan Rachuri, Sebti Foufou
Long-term preservation of product data is imperative for many organizations. A product data archive should be designed to ensure information accessibility and understanding over time. Approaches such as the Open Archival Information System (OAIS) Reference

Inferring Intention Through State Representations in Cooperative Human-Robot Environments

June 7, 2013
Author(s)
Craig I. Schlenoff, Anthony Pietromartire, Zeid Kootbally, Stephen B. Balakirsky, Thomas R. Kramer, Sebti Foufou
In this paper, we describe a novel approach for inferring intention during cooperative human-robot activities through the representation and ordering of state information. State relationships are represented by a combination of spatial relationships in a

Metrics and Test Methods for Industrial Kit Building

June 5, 2013
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer, Zeid Kootbally, Anthony Pietromartire
The IEEE RAS Ontologies for Robotics and Automation Working Group is dedicated to developing a methodology for knowledge representation and reasoning in robotics and automation. As part of this working group, the Industrial Robots sub-group is tasked with

An Optimization Approach for Semantic-based XML Schema Matching

May 16, 2013
Author(s)
Jaewook Kim, Yun Peng, Nenad Ivezic, Jun H. Shin
We propose a novel solution for semantic-based XML schema matching, taking a mathematical programming approach. This method identifies the globally optimal solution for the problem of matching leaf nodes between two XML schema trees by reducing the tree-to

On Enhancing Communication of Manufacturing Service Capability Information

May 16, 2013
Author(s)
Boonserm Kulvatunyou, Nenad Ivezic, Yunsu Lee
A manufacturing service model contains both schema and schema-compliant descriptions of suppliers’ service information, such as locations, areas of specialization, capacities, certifications, software capabilities, and material processing capabilities

Size tolerancing revisited: A basic notion and its evolution in standards

May 13, 2013
Author(s)
Vijay Srinivasan, Edward P. Morse
Size is a fundamental descriptor of objects – it allows us to quantify 'how big' objects are, and to compare and classify objects based on this notion. In the world of ISO GPS (Geometrical Product Specification and Verification), size is defined much more

Engineering Change Management Concepts for Systems Modeling

April 22, 2013
Author(s)
Conrad E. Bock, Allison Barnard Feeney
A significant cost of manufactured systems arises in changing system specifications after they have been built and delivered to customers. This might be due to errors in the original specifications, feedback from customers, competition from other producers

Concept Analysis to Enrich Manufacturing Service Capability Models

March 22, 2013
Author(s)
Jun H. Shin, Boonserm Kulvatunyou, Yunsu Lee, Nenad Ivezic
When an Original Equipment Manufacturer (OEM), which makes a final product for the consumer marketplace by purchasing components from its suppliers, faces unexpected supply network failures and market events, models of suppliers’ manufacturing service

Requirements Analysis for Safer Ambulance Patient Compartments

March 22, 2013
Author(s)
Mehdi Dadfarnia, Yung-Tsun T. Lee, Allison Barnard Feeney, Deogratias Kibira
Providing emergency care services in the confined space of the patient compartment of a moving ambulance is a hazardous activity. A National Institute of Standards & Technology (NIST)/Department of Homeland Security (DHS) project is applying systems

A Semantic Framework for Systems Engineering Standards

March 19, 2013
Author(s)
Allison Barnard Feeney, David M. Price, Albert W. Jones
Systems engineers and asset managers create and maintain models of components and systems associated with long-lived, engineering assets. Component models come from many domains, disciplines and applications. System models typically require integration of
