Synchrotron 4-dimensional imaging of two-phase flow through porous media

July 13, 2016
Author(s)
Felix H. Kim, D. Penumadu, P. Patel, X. Xiao, E. J. Garboczi, Shawn P. Moylan, M A. Donmez
Near real-time visualization of complex two-phase flow in a porous medium was demonstrated with dynamic 4D (3D + time) imaging at the 2-BM beam line of the Advanced Photon Source (APS) at Argonne National Laboratory. Advancing fluid fronts through tortuous

Mobile Manipulator Performance Measurement Towards Manufacturing Assembly Tasks

July 12, 2016
Author(s)
Roger V. Bostelman, Sebti Foufou, Steven A. Legowik, Tsai H. Hong
Mobile manipulator performance measurement research is relatively minimal as compared to that of robot arms. Measurement methods, such as optical tracking systems, are useful for measuring the performances of mobile manipulators, although at a much higher

Model-based engineering for the integration of manufacturing systems with advanced analytics

July 10, 2016
Author(s)
David Lechevalier, Anantha Narayanan Narayanan, Sudarsan Rachuri, Sebti Foufou, Yung-Tsun Lee
To employ data analytics effectively and efficiently on manufacturing systems, engineers and data scientists need to collaborate closely to bring their domain knowledge together. In this paper, we introduce a domain-specific modeling approach to integrate

Implementing the ISO 15746 Standard for Chemical Process Optimization

July 3, 2016
Author(s)
Guodong Shao, Peter O. Denno, Albert T. Jones, Yan Lu
Integrating advanced process control solutions with optimization (APC-O) solutions, within any factory, enables more efficient production processes. Currently, vendors who provide the software applications that implement control solutions are isolated and

Technical Data Packages (TDPs) from the Smart Manufacturing Systems (SMS) Test Bed

July 1, 2016
Author(s)
Thomas D. Hedberg, Moneer M. Helu, Allison Barnard Feeney
Data is collected from the Manufacturing Lab using the MTConnect standard. That data is aggregated and published internally and externally of NIST via web services. Three channels of data dissemination are available or becoming available from the SMS Test

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016
Author(s)
Felipe F. Lopez, Paul Witherell, Brandon Lane
A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced

Survey of Research for Performance Measurement of Mobile Manipulators

June 30, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong, Jeremy A. Marvel
This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles, as com-pared to other mobile manipulator research areas. The survey begins with a

Reusing Metamodels and Notation with Diagram Definition

June 28, 2016
Author(s)
Conrad E. Bock, Maged Elaasar
It is increasingly common for language specifications to separate visual forms (concrete syntax) from underlying concepts (abstract syntax), enabling languages to define multiple visual forms for the same underlying concepts, and for the same visual form

Framework for Standardization of Simulation Integrated Production Planning

June 15, 2016
Author(s)
Deogratias Kibira, Guodong Shao, Bjoern J. Johansson
Production planning is a complex problem that is typically decomposed into decisions carried out at different control levels. Production planning methods employed often assume a static environment; therefore, the plans developed may not be feasible if shop

Propagation of Error from Registration Parameters to Transformed Data

June 6, 2016
Author(s)
Mili Shah, Marek Franaszek, Geraldine Cheok
Methods to register two sets of data have existed for quite some time. However, these sets of data are rarely error-free. Consequently, any parameters obtained from a registration method will be affected by the error in the sets of data. Moreover, if these

Methods and Tools for Performance Assurance of Smart Manufacturing Systems

June 2, 2016
Author(s)
Deogratias Kibira, Katherine C. Morris, Senthilkumaran Kumaraguru
The emerging concept of smart manufacturing systems is defined in part by the introduction of new technologies that are promoting rapid and widespread information flow within the manufacturing system and surrounding its control. These systems can deliver

Test Methods for Robot Agility in Manufacturing

June 2, 2016
Author(s)
Anthony J. Downs, William S. Harrison, Craig I. Schlenoff
In today's world of fast-paced change and ever evolving technologies, there is constant pressure on manufactures for agile production. The need for customization and robustness require today's manufacturers to shift production goals quickly, and address

Recommendations for Autonomous Industrial Vehicle Performance Standards

May 31, 2016
Author(s)
Roger V. Bostelman
A workshop was held at the IEEE International Conference on Robotics and Automation, called: "Autonomous Industrial Vehicles: From the Laboratory to the Factory Floor." Nine research papers were presented followed by a discussion session summarized in this
