The workshop "Bridging communities in the field of nanomedicine" was hosted by the European Commission Joint Research Centre on 27-28 September 2017. It gathered experts from regulatory bodies, research institutions and industry to discuss the main

Sources of Errors in Structured Light 3D Scanners

April 15, 2019
Author(s)
Prem K. Rachakonda, Bala Muralikrishnan, Daniel S. Sawyer
Structured light (SL) scanners have been commercially available for over a decade and some commercial scanners are evaluated using one of two German guidelines – VDI/VDE 2634 parts 2 and/or 3. Several other research groups and NMIs have developed physical

Methods to Characterize 3D Scanners for Forensic Applications

February 22, 2019
Author(s)
Prem K. Rachakonda, Balasubramanian Muralikrishnan
Forensic photography has been one of the most valuable tool for investigators over many decades. They preserve the history of the scene and provide a way for investigators to analyze the scene of interest. However, it is difficult to obtain any objective

Author(s)
R M. Verkouteren, Nathanael A. Heckert, Stefan D. Leigh, Edward R. Sisco, James E. Norris, Jeffrey A. Lawrence, Amber Burns
The performance characteristics of explosive and narcotic trace detectors are mission-critical to agencies worldwide that are charged with protection of the public, defense for mass transit and infrastructure, and the safety of first responders. Commercial

NIST Handbook 150-8, NVLAP Acoustical Testing Services

November 19, 2018
Author(s)
Kari K. Harper
NIST Handbook 150-8 presents technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Acoustical Testing Services program. It is intended for information and use by

Operating Hydrogen Gas Transmission Pipelines at Pressures above 21 MPa

November 12, 2018
Author(s)
Andrew Slifka, Elizabeth S. Drexler, Robert L. Amaro, Peter Bradley, Damian Lauria
The economical and efficient transportation of hydrogen gas is necessary for it to become a widespread source of energy. One way to improve the economics is to lower the cost of building hydrogen gas pipelines. The recent modification to the ASME B31.12

Innovative Approaches to Combat Healthcare-Associated Infections Using Efficacy Standards Developed Through Industry and Federal Collaboration

October 5, 2018

Dianne L. Poster, Carl C. Miller, Yaw S. Obeng, Michael T. Postek, Troy E. Cowan, Richard A. Martinello
Nation-wide, healthcare-associated infections (HAIs) infect one in every 25 hospital patients, account for more than 100,000 deaths and increase medical costs by around $96-147B, each year. Ultraviolet-C (UV-C) antimicrobial devices are shown to reduce the

Roles and Responsibilities of NIST in the Development of Documentary Standards

July 27, 2018
Author(s)
Prem K. Rachakonda, Balasubramanian Muralikrishnan, Daniel S. Sawyer
The National Institute of Standards and Technology (NIST) is a non-regulatory federal agency of the Department of Commerce and is the national metrology institute of the US. The background of NIST's role in the development of voluntary consensus standards

ASTM E3125 Laser Scanner Standard: Challenges and Role of NIST

July 24, 2018
Author(s)
Prem K. Rachakonda
The Dimensional Metrology Group (DMG) at National Institute of Standards & Technology (NIST), along with various other organizations were involved in the development of the ASTM E3125-17 documentary standard for 3D imaging systems. The ASTM E57 committee

Characterization of Five-Hole Probes used for Flow Measurement in Stack Emission Testing

May 16, 2018
Author(s)
Iosif Isaakovich Shinder, Aaron Johnson, Michael R. Moldover, James Filla, Vladimir Khromchenko
We report progress towards the goal of reducing the errors in industrial smokestack flow measurements to 1 % by replacing S-probes with calibrated 3-D probes (i.e., probes that measure 3 components of velocity). NIST calibrated a commercially-manufactured
