Metrics for Mixed Pallet Stacking

January 31, 2011
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer, Frederick M. Proctor
Stacking boxes of various sizes and contents on pallets (i.e. making mixed pallets) is a primary method of preparing goods for shipment from a warehouse to a store or other distant site. Many billions of dollars are spent each year in preparing, shipping

Using Simulation To Assess The Effectiveness of Pallet Stacking Methods

November 19, 2010
Author(s)
Stephen B. Balakirsky, Frederick M. Proctor, Thomas R. Kramer, Pushkar Kolhe, Henrik I. Christensen
Stacking objects onto pallets is the most widely used method of bulk shipping, accounting for over 60% of the volume of goods shipped worldwide. Due in part to the wide variation in size, shape and weight of objects to be palletized, successful stacking is

An Advanced Patient Lift and Transfer Device for the Home

October 29, 2010
Author(s)
Roger V. Bostelman, Ji-Chul Ryu, Tommy Chang, Joshua Johnson, S K. Agrawal
The Home Lift, Position and Rehabilitation (HLPR) Chair has a unique design and novel capabilities when compared to conventional powered wheelchairs. In addition to mobility, it provides lift and can transfer patients. Even though medical devices are

Performance Assessment of Face Recognition Using Super-Resolution

October 25, 2010
Author(s)
Shuowen Hu, Robert Maschal, S. S. Young, Tsai H. Hong, P. Jonathon Phillips
Recognition rate of face recognition algorithms is dependent on the resolution of the imagery, specifically the number of pixels contained within the face. Using a sequence of frames from low-resolution videos, super-resolution reconstruction can form a

Methodology for evaluating Static six-degree-of-freedom (6DoF) Perception Systems

October 15, 2010
Author(s)
Tommy Chang, Tsai H. Hong, Joseph Falco, Michael O. Shneier, Milli Shah, Roger D. Eastman
In this paper, we apply two fundamental approaches toward evaluating a static, vision based, six-degree-of-freedom (6DoF) pose determination system that measures the position and orientation of a part. The first approach uses ground\-truth carefully

Variability in the Geometric Accuracy of Additively Manufactured Test Parts

August 9, 2010
Author(s)
April L. Cooke, Johannes A. Soons
Results of a study on the variability in the geometric accuracy of a metal test part manufactured by several service providers using either electron beam or laser based powder bed thermal fusion processes are described. The part was a circle-diamond-square

2009 Performance Metrics for Intelligent Systems (PerMIS'09) Workshop

July 9, 2010
Author(s)
Rajmohan Madhavan, Elena R. Messina
The Performance Metrics for Intelligent Systems (PerMIS) workshop is dedicated to defining measures and methodologies of evaluating performance of intelligent systems. The main theme of the ninth iteration of the workshop, PerMIS'09, addressed the question

Ultra-Precision Linear Motion Metrology

June 23, 2010
Author(s)
Ronnie R. Fesperman Jr., M A. Donmez, Shawn P. Moylan
Many new emerging applications of nanotechnologies require the use of compact precision linear translation stages that have positioning resolution on the order of a nanometer and an exceptionally long range of motion on the order of tens of millimeters
