An Evolving Regulatory Landscape for Commercial Electric Vehicle Fueling

August 22, 2023
Author(s)
Tina G. Butcher, Michael Nelson
Plug-in electric vehicles (PEV), which include "all-electric" battery EV (BEV) and plug-in hybrid EV (PHEV), comprise a rapidly growing proportion of the U.S. automobile market – nearly 8% of all light-duty vehicles sold in Oct. 2022, a 41.4% rise over

Recommendations for Setting a Criterion for Assessing Commutability of Secondary Calibrator Certified Reference Materials

August 11, 2023

W. Greg Miller, Thomas Keller, Jeffrey Budd, Jesper Johansen, Mauro Panteghini, Neil Greenberg, Vincent Delatour, Ferruccio Ceriotti, Robert Rej, Johanna Camara, Liesbet Deprez, Finlay MacKenzie, Alicia Lyle, Eline van der Hagen, Chris Burns, Pernille Fauskanger, Sverre Sandberg
A secondary higher-order calibrator is required to be commutable with clinical samples to be suitable for use in the calibration hierarchy of an end-user clinical laboratory in vitro diagnostic medical device (IVD-MD). Commutability is a property of a

Synthetic Aperture RF Reception using Rydberg Atoms

Nik Prajapati, Aly Artusio-Glimpse, Matt Simons, Samuel Berweger, Drew Rotunno, Maitreyi Jayaseelan, Kaleb Campbell, Christopher L. Holloway
Rydberg atoms show great promise for use as self-calibrated electric field sensors for a broad range of frequencies. Their response is traceable to the international system of units making them a valuable tool for a variety of applications including

Redundant Ballistic Chronograph Configuration for Body Armor Testing

July 28, 2023
Author(s)
Michael A. Riley, Nicholas G. Paulter Jr., Dwight D. Barry
A new configuration of the light screen pairs used in a redundant ballistic chronograph is described. This configuration complies with current ASTM International and National Institute of Justice requirements for measuring the ballistic performance of body

Enabling FAIR Data in Additive Manufacturing to Accelerate Industrialization

July 24, 2023
Author(s)
Shengyen Li, Yan Lu, Kareem Aggour, Peter Coutts, Brennan Harris, Alex Kitt, Afina Lupulescu, Luke Mohr, Mike Vasquez
Additive manufacturing (AM) is an important enabler of Industry 4.0 but there are several hurdles that need to be overcome to fully realize the potential of AM. These challenges include the need for a data infrastructure to enable the scaling of the

Standards as Enablers for a Circular Economy

June 30, 2023
Author(s)
KC Morris, Vincenzo Ferrero, Buddhika Hapuwatte, Noah Last, Nehika Mathur
A successful transition to a circular economy (CE) will require global participation, but the path to that transition will follow many unique routes depending on local situations. The transition must have rigorous technical underpinnings and well-conceived

In Vivo Quantitative MRI T1 and T2 Measurements of the Human Brain at 0.064 T

May 20, 2023
Author(s)
Kalina Jordanova, Michele Martin, Stephen Ogier, Megan Poorman, Katy Keenan
Object : Tissue relaxation of the brain is measured in vivo at 0.064 T. This work contributes to research efforts targeted at measuring quantitative magnetic resonance imaging properties of the human body at lower field strengths, thereby increasing the

Advanced Encryption Standard (AES)
