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

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

Modeling and Simulation Analysis Types for Sustainable Manufacturing

October 6, 2010
Author(s)
Deogratias Kibira, Guodong Shao, Yung-Tsun T. Lee
Sustainable manufacturing could be further be promoted by the effective use of Modeling and Simulation (M&S) applications. These applications can evaluate manufacturing operations in light of increasing legislation and awareness for environmental

Future SC4 Architecture PWI - Report and Technical Discussion

October 1, 2010
Author(s)
Allison Barnard Feeney
This document is the report of the Future SC4 architecture PWI. It provides information about the draft “Industrial Data Integrated Ontologies and Models (IDIOM) architecture specification” created by the PWI. The work of the Preliminary Work Item (PWI)

CMSD: A Model Supporting Manufacturing and Simulation Application Integration

September 20, 2010
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee
Standard representations for key manufacturing entities could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications. This change would make the use of simulation technology
