NVLAP Federal Warfare System(s)

July 21, 2021
Bradley Moore, John Matyjas, Raymond Tierney, Jesse Angle, Jeannine Abiva, Jeff Hanes, David Dobosh, John Avera
NIST Handbook 150-872 presents the technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Federal Warfare System(s) (FWS) program. It is intended for information and

National Institute of Standards and Technology Environmental Scan 2020

February 9, 2021
Heather Evans, Kristen K. Greene, William M. Healy, Elizabeth Hoffman, Kate Rimmer, Anna V. Sberegaeva, Neil M. Zimmerman
The 2020 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through four separate lenses

Fatigue Testing of Pipeline Welds and Heat-Affected Zones in Pressurized Hydrogen Gas

April 26, 2019
Elizabeth S. Drexler, Andrew J. Slifka, Robert L. Amaro, Jeffrey W. Sowards, Matthew J. Connolly, May L. Martin, Damian S. Lauria
Several welds and associated heat-affected zones (HAZs) on two API X70 and two API X52 pipes were tested to determine the fatigue crack growth rate (FCGR) in pressurized hydrogen gas and assess the area of the pipe that was most susceptible to fatigue when

Fundamentals and characterizations of scratch resistance on automotive clearcoats

September 11, 2018
Li Piin Sung, Linqian Feng, Nadia Benhamida, Pierre Morel, Andrew T. Detwiler, Jon M. Skelly, Leslie T. Baker, Deepanjan Bhattacharya
As original equipment manufacturers (OEMs) strive to deliver improved coating performance with a sustainable footprint, opportunities for innovation are emerging, particularly on improving mechanical properties, appearance, and solids content. Resistance

Cooperative Vehicular Networking: A Survey

March 8, 2018
Hamid Gharavi
With the remarkable progress of cooperative communication technology in recent years, its transformation to vehicular networking is gaining momentum. Such a transformation has brought a new research challenge in facing the realization of cooperative


July 31, 2017
Andrew Slifka, Robert L. Amaro, Devin T. O'Connor, Benjamin E. Long, Elizabeth S. Drexler
In this work, we applied a finite element model to predict the cyclic lifetime of 4130 steel cylinders under the influence of hydrogen. This example is used to demonstrate the efficacy of a fatigue crack growth (FCG) model we have developed. The model was


July 31, 2017
Andrew Slifka, Robert L. Amaro, Elizabeth S. Drexler, Devin T. O'Connor, Benjamin E. Long
In this work we further develop a model to predict hydrogen-assisted fatigue crack growth in steel pipelines and pressure vessels. This implementation of the model is informed by finite element code, which uses an elastic-plastic constitutive model in

Application of the Advanced Distillation Curve Method to the Comparison of Diesel Fuel Oxygenates: 2,5,7,10-Tetraoxaundecane (TOU), 2,4,7,9-Tetraoxadecane (TOD), and Ethanol/Fatty Acid Methyl Ester (FAME) Mixtures

June 22, 2017
Jessica L. Burger, Tara M. Lovestead, Mark LaFollette, Thomas J. Bruno
Although they are amongst the most efficient engine types, compression-ignition engines have difficulties achieving acceptable particulate emission and NOx formation. Indeed, catalytic after-treatment of diesel exhaust has become common and current efforts

Review of Research for Docking Automatic Guided Vehicles and Mobile Robots

October 13, 2016
Roger V. Bostelman, Tsai H. Hong
This survey provides a literature review of docking research, an area that has relatively few research articles as compared to generic automatic guided vehicle (AGV) or mobile robot research. Docking refers to the arrival and act of a vehicle stopping at a

Comparison of Registration Methods for Mobile Manipulators

September 15, 2016
Roger V. Bostelman, Roger Eastman, Tsai H. Hong, Omar Aboul-Enein, Steven A. Legowik, Sebti Foufou
Mobile manipulators can be effective, efficient and flexible for automation on the factory floor but will need safety and performance standards for wide adoption. This paper looks at a specific area of performance standards [1] for docking and workpiece

Anti-corrosive influence of Acetobacter biofilms on carbon steel

July 19, 2016
Danielle C. France
Microbiologically influenced corrosion (MIC) of carbon steel infrastructure is an emerging cost issue for the ethanol fuel industry. One bacterial species found in ethanol fuel environments, Acetobacter aceti, can convert ethanol to the corrosive species

Mobile Manipulator Performance Measurement Towards Manufacturing Assembly Tasks

July 12, 2016
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

Survey of Research for Performance Measurement of Mobile Manipulators

June 30, 2016
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

Recommendations for Autonomous Industrial Vehicle Performance Standards

May 31, 2016
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
