Time-series Imputation Algorithm

November 5, 2021
Author(s)
David A. Howe, Chloe Champagne
Statistical imputation is a field of study that attempts to fill missing data. It is commonly applied to population statistics whose data have no correlation with running time. For a time series, data is typically analyzed using the autocorrelation, the

User Perceptions & Preferences for Smart Home Device Updates

November 5, 2021
Author(s)
Susanne M. Furman, Julie Haney
IoT smart home updates are a critical mechanism by which manufacturers can remediate security vulnerabilities and one of the few tools users have to secure their devices. Yet, security professionals view difficulties in patching IoT devices as a major

AGILE TASKING OF ROBOTIC KITTING

November 4, 2021
Author(s)
John L. Michaloski, Craig I. Schlenoff, Murat Aksu, Rafael Cardoso, Michael Fisher
Manufacturers are looking for intelligent solutions to increase quality and productivity. Smart manufacturing envisions production empowered by autonomous robots that can complete tasks intelligently, with the focus on adaptability, flexibility, and

Quantifying and Suppressing Proton Intercalation to Enable High-Voltage Zn-Ion Batteries

November 4, 2021
Author(s)
Fei Wang, Lauren E. Blanc, Qin Li, Antonio Faraone, Xiao Ji, Huaiyu H. Chen-Mayer, Rick L. Paul, Joseph Dura, Enyuan Hu, Kang Xu, Linda F. Nazar, Chunsheng Wang
We explore the Zn-ion intercalation mechanisms/interfacial dynamics of VPO 4F and quantify the water dynamics in water-in-salt (WISE) and hybrid aqueous-non aqueous electrolytes (HANEs). We demonstrate that H + intercalation dominates electrochemical

Semiclassical Theory of Photon Echoes with Application to Pr:YSO

November 4, 2021
Author(s)
Zachary H. Levine
Coherent states are used to prepare a crystal using the Atomic Frequency Comb protocol for quantum memory. Here, semiclassical theory is developed and compared to experimental photon echoes of a coherent pulse.

A Resilient Architecture for the Realization and Distribution of Coordinated Universal Time to Critical Infrastructure Systems in the United States: Methodologies and Recommendations from the National Institute of Standards and Technology (NIST)

November 3, 2021
Author(s)
Jeffrey Sherman, Ladan Arissian, Roger Brown, Matthew J. Deutch, Elizabeth Donley, Vladislav Gerginov, Judah Levine, Glenn Nelson, Andrew Novick, Bijunath Patla, Tom Parker, Benjamin Stuhl, Jian Yao, William Yates, Michael A. Lombardi, Victor Zhang, Douglas Sutton
The Time and Frequency Division of the National Institute of Standards and Technology (NIST), an agency of the United States Department of Commerce (DOC), was tasked with fulfilling Section 4, Part (i) of the Position, Navigation and Timing (PNT) Executive

Laser spot size and scaling laws for laser beam additive manufacturing

November 3, 2021
Author(s)
Jordan Weaver, Jarred C. Heigel, Brandon Lane
Laser powder bed fusion (L-PBF) additive manufacturing (AM) requires the careful selection of laser process parameters for each feedstock material and machine, which is a laborious process. Scaling laws based on the laser power, speed, and spot size; melt

Privacy-enhancing cryptography to complement differential privacy

November 3, 2021
Author(s)
Luis Brandao, Rene Peralta
In this post, we illustrate how various techniques from privacy-enhancing cryptography, coupled with differential privacy protection, can be used to protect data privacy while enabling data utility. Of notable interest is the setting where there are
