This product, Core Manufacturing Simulation Data (CMSD), addresses interoperability between simulation systems and other manufacturing applications. The CMSD information model is a standard representation for core manufacturing simulation data. It provides

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

PUSH-BUTTON DISCRETE EVENT SIMULATION FOR ANALYSIS OF FACTORY FLOOR OPERATIONS

November 18, 2010
Author(s)
John L. Michaloski, Byeong Eon Lee, Frederick M. Proctor, Sid Venkatesh, Nils Bengtsson, Anders Skoogh, Benjamin Raverdy
In manufacturing, Discrete Event Simulation (DES) can be effectively used to model production and provide sustainability analysis of equipment and system operation by measuring throughput, capacity, and bottlenecks. DES allows analysis under different

Modeling, Simulation and Analysis for Sustainable Product Development

Maintainers Manual for Version 2.2.1 of the NIST DMIS Test Suite

October 25, 2010
Author(s)
Thomas R. Kramer, John A. Horst
This manual is a maintainers manual for the NIST DMIS Test Suite, version 2.2.1. DMIS (Dimensional Measuring Interface Standard) is a language for writing programs for coordinate measuring machines and other dimensional measurement equipment. The manual is

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

Vision Guided Multi-Probe Assembly of 3D Microstructures

October 20, 2010
Author(s)
John D. Wason, John T. Wen, Young M. Choi, Jason J. Gorman, Nicholas Dagalakis
This paper describes the operator assisted automated assembly of a 3-legged spatial platform by using a vision guided multi-probe assembly process. This is the first step towards the ultimate goal of building a microscale active spatial platform. Two

Accurate Measurements of Process Gas Flow with Laminar Flow Meters

October 15, 2010
Author(s)
Thiago Cobu, Robert F. Berg, John D. Wright, Michael R. Moldover
We calibrated three models of commercially-manufactured, laminar flow meters (LFMs) with nitrogen at four pressures (100 kPa, 200 kPa, 300 kPa, and 400 kPa) over a 10:1 flow range using NIST’s primary flow standards and a physical model. Without additional

Lessons Learned in Evaluating DARPA Advanced Military Technologies

October 15, 2010
Author(s)
Craig I. Schlenoff, Brian A. Weiss, Michelle P. Steves
For the past six years, personnel from the National Institute of Standards and Technology (NIST) have served as the Independent Evaluation Team (IET) for two major DARPA programs. DARPA ASSIST (Advanced Soldier Sensor Information System and Technology) is

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

Properties for Accurate Gas Flow Measurements

October 15, 2010
Author(s)
John D. Wright
Accurate gas properties are needed to take full advantage of the low uncertainties provided by NIST’s Gas Flow Calibration Services. If a flowmeter user and NIST use different values for these properties (molecular mass, compressibility, density, viscosity
