Encryption is Futile: Reconstructing 3D-Printed Models using the Power Side-Channel

October 6, 2021
Jacob Gatlin, Sofia Belikovetsky, Yuval Elovici, Anthony Skjellum, Joshua Lubell, Paul Witherell, Mark Yampolskiy
Outsourced Additive Manufacturing (AM) exposes sensitive design data to external malicious actors. Even with end-to-end encryption between the design owner and 3D-printer, side-channel attacks can be used to bypass cyber-security measures and obtain the

Requirement elicitation for adaptive standards development

September 27, 2021
Marion Toussaint, Sylvere Krima, Allison Barnard Feeney, HERVE PANETTO
The recent digitization of manufacturing, also referred to as the fourth industrial revolution (or Industry 4.0), heavily relies on information standards for the exchange and integration of digital data across manufacturers and their partners. Standards

Reference Correlation for the Thermal Conductivity of Ethane-1,2-diol (Ethylene Glycol) from the Triple Point to 475 K and Pressures up to 100 MPa

September 14, 2021
Marko Mebelli, Danai Velliadou, Marc Assael, Konstantinos D. Antoniadis, Marcia L. Huber
We present a new wide-ranging correlation for the thermal of ethane-1,2-diol (ethylene glycol) based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point

Visualizing Model-based Product Definitions in Augmented Reality

August 23, 2021
Teodor Vernica, Robert R. Lipman, William Z. Bernstein
Augmented reality (AR) technologies present immense potential for the design and manufacturing communities. However, coordinating traditional engineering data representations into AR systems without loss of context and information remains a challenge. A

Dianne L. Poster, C Cameron Miller, Richard Martinello, Norman Horn, Michael T. Postek, Troy Cowan, Yaw S. Obeng, John J. Kasianowicz
The National Institute of Standards and Technology (NIST) hosted an international workshop on ultraviolet-C (UV-C) disinfection technologies on January 14 – 15, 2020 in Gaithersburg, Maryland in collaboration with the International Ultraviolet Association

A System for Validating Resistive Neural Network Prototypes

July 27, 2021
Brian Hoskins, Mitchell Fream, Matthew Daniels, Jonathan Goodwill, Advait Madhavan, Jabez J. McClelland, Osama Yousuf, Gina C. Adam, Wen Ma, Muqing Liu, Rasmus Madsen, Martin Lueker-Boden
Building prototypes of heterogeneous hardware systems based on emerging electronic, magnetic, and photonic devices is an increasingly important area of research. On the face of it, the novel implementation of these systems, especially for online learning

Comparison Demonstrates Factor of Three Improvement in Gas Flow Measurements

July 21, 2021
John D. Wright, Gina Kline, Kevin John, Brian Novitsky, Jason Bellavance, Kevin SHufelt, Bradley Nease, Miles Owen, Joseph Allen, Casey Rombouts, William Gause, John Cuccio
A comparison of seven gas flow calibration laboratories piloted by NIST used four laminar flow meters as the transfer standards for nine nitrogen gas flows ranging from 1 sccm to 10 slm. The comparison reference value was calculated from the uncertainty

June 30, 2021
Eite Tiesinga, Peter Mohr, David B. Newell, Barry Taylor
We report the 2018 self-consistent values of constants and conversion factors of physics and chemistry recommended by the Committee on Data of the Interna- tional Science Council (CODATA). The recommended values can also be found at


June 15, 2021
Jodie Gail Pope, Aaron Johnson, James Filla, Vern E. Bean, Michael R. Moldover, Joey Boyd, Christopher J. Crowley, Iosif Isaakovich Shinder, Keith A. Gillis, John D. Wright
We describe the 15 kg/s water flow calibration standard operated by the Fluid Metrology Group of the National Institute of Standards and Technology (NIST) to calibrate liquid flow meters for customers. The 15 kg/s standard is a dynamic, gravimetric, liquid

May 20, 2021
Kathryn Miller
The National Institute of Standards and Technology is a nonregulatory agency of the U.S. Department of Commerce. One of the agency's responsibilities is to develop industry standards and guidelines, which are published as NIST Technical Series publications

Study of 5G New Radio (NR) Support for Direct Mode Communications

May 7, 2021
Fernando Cintron, David Griffith, Chunmei Liu, Richard A. Rouil, Yishen Sun, Jian Wang, Peng Liu, Chen Shen, Aziza Ben Mosbah, Samantha Gamboa Quintiliani
In public safety communications, direct mode communication is essential to keep first responders connected, especially when there is no network coverage. Direct mode communication is supported in Third Generation Partnership Project (3GPP) Long Term

Use Case Scenarios for Digital Twin Implementation Based on ISO 23247

May 4, 2021
Guodong Shao
As a key part of digital transformation, digital twin is an important concept for achieving smart manufacturing. However, there remains a lot of confusion about the digital twin concept and how it can be implemented in real manufacturing systems

The importance of international standards for the graphene community
