Using Competitions to Advance the Development of Standard Test Methods for Response Robots

May 17, 2012
Author(s)
Adam S. Jacoff, Raymond Sheh, Ann Virts, Tetsuya Kimura, Johannes Pellenz, Soren Schwertfeger, Jackrit Suthakorn
Competitions are an effective aid to the development and dissemination of standard test methods, especially in rapidly developing, highly varied fields such as Urban Search and Rescue robotics. By exposing the development process to highly developmental

Web-enabled, Real-time, Quality Assurance for Machining Production Systems

April 19, 2012
Author(s)
John L. Michaloski
In order to maintain the close control of production quality, frequent measurement and process parameter adjustments are desirable. In the discrete parts industry, part inspection is intended to be a metric for the process quality but quality control is

Performance Evaluation of Robotic Knowledge Representation (PERK)

March 22, 2012
Author(s)
Craig I. Schlenoff, Sebti Foufou, Stephen B. Balakirsky
In this paper, we explore some ways in which symbolic knowledge representations have been evaluated in the past and provide some thoughts on what should be considered when applying and evaluating these types of knowledge representations for real-time

An Analysis of Solver-Based Simulation Tools

March 7, 2012
Author(s)
Ion Matei, Conrad E. Bock
Computer-interpretable representations of systems’ structure and behavior are at the center of designing today’s complex systems. Engineers create and review such representations using (graphical) modeling languages that support specification, analysis

New Capabilities for Interaction Modeling in BPMN 2.0

January 15, 2012
Author(s)
Conrad E. Bock, Stephen White
Interaction models capture how businesses interact with customers and each other to provide products and services. The trend toward combinations of products and services increases the complexity of interactions beyond the capacity of conventional business

A Semantic Product Modeling Framework and Its Application for Behavior Evaluation

January 9, 2012
Author(s)
Jae H. Lee, Steven J. Fenves, Conrad E. Bock, Sudarsan Rachuri, Hyo-Won Suh, Xenia Fiorentini, Ram D. Sriram
Supporting different stakeholder viewpoints across the product’s entire lifecycle requires semantic richness to represent product related information and thus enable multi-view engineering simulations. This paper proposes a multi-level product modeling

XML Validation Website: A User's Guide

November 16, 2011
Author(s)
Julien C. Cuvillier, Katherine C. Morris
This report describes the XML Validation website which hosts a number of XML parsing tools that can be used to remotely validate XML schema files against the W3C XML Schema standard, and XML data files against their corresponding XML schemas. The first

Architectural Recommendations for Global Interoperability Test Bed

October 28, 2011
Author(s)
Nenad Ivezic
This paper offers a collection of recommendations to architect a comprehensive and coherent architectural solution for a global interoperability testing framework for eBusiness systems. Requirements from an initial set of three industrial use cases drove

Trust Based Multi-Agent Filtering for Increased Smart Grid Security

October 24, 2011
Author(s)
Ion Matei, Vijay Srinivasan
We address the problem of state estimation of the power system for the Smart Grid.We assume that the monitoring of the electrical grid is done by a network of agents with both computing and communication capabilities. We propose a security mechanism aimed

Metamodels towards Improved Domain Modeling for Semantic Inferencing

October 3, 2011
Author(s)
Paul W. Witherell, Anantha Narayanan Narayanan, Jae H. Lee, Sudarsan Rachuri
As information requirements have increased, domain models have become increasing complex and difficult to manage. Though domain-specific languages have been developed for domain experts, increasing their expressivity and decreasing their complexity, their

DEXML: A FIRST STEP TOWARD A UML BASED IMPLEMENTATION FRAMEWORK FOR PLCS

August 31, 2011
Author(s)
Sylvere I. Krima, Joshua Lubell, Sudarsan Rachuri, Roch Bertucat, Sebti Foufou
Data exchange specifications not only must be broad and general to achieve acceptance, but also must be customizable in a controlled and interoperable manner to be useful. The Product Life Cycle Support (PLCS) suite of data exchange specifications (known

We address the problem of state estimation of the power system for the Smart Grid.We assume that the monitoring of the electrical grid is done by a network of agents with both computing and communication capabilities. We propose a security mechanism aimed

MBE Standardization and Validation

July 6, 2011
Author(s)
Joshua Lubell, Nathan W. Hartman, Doug Cheney
3D Model-Based Engineering (MBE) is an approach to product design, manufacturing, and support where a digital three-dimensional representation of the product serves as the normative source for information communicated throughout the product’s lifecycle and

NIST Special Publication (SP) 800-82, Guide to Industrial Control Systems (ICS) Security, provides guidance on how to secure Industrial Control Systems (ICS), including Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems

Agile Test Framework for Business-to-Business Interoperability

April 12, 2011
Author(s)
Jungyub Woo, Nenad Ivezic, H Cho
Business-to-business (B2B) applications are tested routinely for conformance and interoperability against a set of data exchange standards before deployment. However, the existence of many data exchange standards, planned utilizations, deployment

William G. Rippey
The Dimensional Metrology Standards Consortium (DMSC) marketing roadshow converged on the International Manufacturing Technology Show (IMTS) 2010 in Chicago this past September. Buoyed by many supporters, the organization showed the importance of

A Component-based Approach for Manufacturing Simulation

March 2, 2011
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee, Deogratias Kibira, Stephen B. Balakirsky
Manufacturing systems can be very complex and are often costly to develop and operate. Simulation technology has been shown to be an effective tool for optimizing manufacturing system design, operations, and maintenance procedures. However, each
