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

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

Semantic B2B-integration Using an Ontological Message Metamodel

September 1, 2010
Author(s)
Marko Vujasinovic, Nenad Ivezic, Edward J. Barkmeyer Jr., Zoran Marjanovic
E-Business applications are often required to use different, incompatible, message sets to implement message interfaces for a business-to-business (B2B) communication. This makes communication with every new partner a new interoperability problem. In this

Framework and Indicators for a Sustainable Manufacturing Mapping Methodology

August 31, 2010
Author(s)
Marja Paju, Juhani Heilala, Markku Hentula, Antti Heikkila, Bjorn Johansson, Swee K. Leong, Kevin W. Lyons
Increasing numbers of companies in the manufacturing industry have identified market potential for implementing sustainable and green manufacturing. Yet, current sustainability assessment tools for companies are complicated, requiring vast amounts of data

OntoSTEP: Enriching Product Model Data Using Ontologies

August 31, 2010
Author(s)
Raphael Barbau, Sylvere I. Krima, Xenia Fiorentini, Sudarsan Rachuri, Anantha Narayanan Narayanan, Sebti Foufou, Ram D. Sriram
The representation and management of product lifecycle information is critical to the success of any manufacturing organization. Different modeling languages are adopted to represent different product information, for example EXPRESS for geometry as seen

System Testing Using Use Cases for Simulation Model of an Emergency Room

August 31, 2010
Author(s)
Guodong Shao
Modeling and simulation (M&S) techniques are increasingly being used to solve problems and aid decision making in many different fields. It is particularly useful for Department of Homeland Security (DHS) applications because of its feature of non

AFM characterization of nanopositioner in-plane stiffnesses

August 19, 2010
Author(s)
Seung Ho Yang, Yong Sik Kim, Premsagar P. Kavuri, Jae M. Yoo, Young M. Choi, Nicholas G. Dagalakis
A versatile method for measurement of in-plane stiffness of micro-elements was developed and its usefulness has been demonstrated. The in-plane stiffness of a NIST nanopositioner has been measured directly using a colloidal probe in an AFM without any

Author(s)
Byeong Eon Lee, John L. Michaloski, Frederick M. Proctor, Sid Venkatesh, Nils Bengtsson
Kaizen is a part of Lean Manufacturing that focuses on the concept of continuous improvement to reduce waste. For implementing Kaizen on the factory floor, comprehensive and efficient tools for data acquisition, process measurement and analysis are

Embedded Capacitive Displacement Sensor for Nanopositioning Applications

August 17, 2010
Author(s)
Svetlana Avramov-Zamurovic1, Nicholas Dagalakis, Rae Duk Lee, Yong Sik Kim, Jae M. Yoo, Seung H. Yang
The scale of nano objects requires very precise position determination. The state-of-the-art manipulators involve accurate nanometer positioning. This paper presents the design of a capacitive displacement sensor for a nanopositioning application. The
