The report highlights the manufacturing innovation projects developed by the institutes and their partners across the country to combat COVID-19. Manufacturing USA network, comprised of federal agencies and their sponsored manufacturing innovation

ON THE FAMILY OF ELLIPTIC CURVES X + 1/X + Y + 1/Y + t = 0

March 23, 2021
Author(s)
Dustin Moody, Abhishek Juyal
We study various properties of the family of elliptic curves x+ 1/x+y+ 1/y+t = 0, which is isomorphic to the Weierstrass curve E_t: Y^2=X(X^2+(t^2/4-2)X+1). This equation arises from the study of the Mahler measure of polynomials. We show that the rank of

Rethinking maintenance terminology for an Industry 4.0 future

March 22, 2021
Author(s)
Melinda Hodkiewicz, Sarah Lukens, Michael Brundage, Thurston Sexton
Sensors and mathematical models have been used since the 1990's to assess the health of systems and diagnose anomalous behavior. The advent of the Internet of Things (IoT) increases the range of assets on which data can be collected cost effectively. Cloud

Cybersecurity Standards and Guidelines to Assist Small and Medium-Sized Manufacturers

March 21, 2021
Author(s)
Timothy Zimmerman, CheeYee Tang, Michael Pease, Keith A. Stouffer
Cybersecurity standards and guidelines produced by NIST can assist small and medium-sized manufacturers to protect their operational technology from cybersecurity threats. NIST cybersecurity standards, guidelines, and research underway at NIST is described

Isotropic Nature of the Metallic Kagome Ferromagnet Fe 3 Sn 2 at High Temperatures

March 20, 2021
Author(s)
Rebecca Dally, Daniel Phelan, Nicholas Bishop, Nirmal J. Ghimire, Jeffrey Lynn
Anisotropy and competing exchange interactions have emerged as two central ingredients needed for centrosymmetric materials to exhibit topological spin textures. Fe 3Sn 2 is thought to have these ingredients as well, as it has recently been discovered to

Exploring the First High Entropy Thin Film Libraries: Composition spread-controlled Crystalline Structure

March 19, 2021
Author(s)
Thi X. Nguyen, Yen-Hsun Su, Jason Hattrick-Simpers, Takahiro Nagata, Howard Joress, Kao-Shuo Chang, Suchismita Sarker, Apurva Mehta, Jyh-Ming Ting
Thin films of two types of high-entropy oxides (HEOs) have been deposited on 76.2 mm Si wafers using combinatorial sputter deposition. In one type of the oxides, (MgZnMnCoNi)Ox, all the metals have a stable divalent oxidation state and similar cationic

Intelligent Task Caching in Edge Cloud via Bandit Learning

March 19, 2021
Author(s)
Hamid Gharavi
Task caching, based on edge cloud, aims to meet the latency requirements of computation- intensive and data-intensive tasks (such as augmented reality). However, current task caching strategies are generally based on the unrealistic assumption of knowing

Damage tolerant design of additively manufactured metallic components subjected to cyclic loading: State of the art and challenges

Uwe Zerbst, Giovanni Bruno, Jean-Yves Buffiere, Thomas Wegener, Tao Wu, Xiang Zhang, Nikolai Kashaev, Giovanni Meneghetti, Nik Hrabe, Mauro Madia, Tiago Werner, Kai Hildgenburg, Radek Proch?zka, Martina Koukol?kov?, Jan D?ugan, Benjamin M?ller, Stefano Beretta, Alexander Evans
Undoubtedly, a better understanding and the further development of approaches for damage tolerant component design of AM parts are among the most significant challenges currently facing the use of these new technologies. This article presents a thorough

Sensors and Machine Learning Models to Prevent Cooktop Ignition and Ignore Normal Cooking

March 18, 2021
Author(s)
Amy Mensch, Anthony Hamins, Andy Tam, John Lu, Kathryn Markell, Christina You, Matthew Kupferschmid
Cooking equipment is involved in nearly half of home fires in the United States, with cooktop fires the leading cause of deaths and injuries in cooking-related fires. In this study, we evaluate 16 electrochemical, optical, temperature and humidity sensors
