Wafer-Level Fabrication of Alkali Vapor Cells Using In-Situ Atomic Deposition

December 14, 2020
Author(s)
Douglas Bopp, Vincent N. Maurice, John Kitching
We demonstrate a new technique for filling microfabricated silicon and glass cavities with alkali vapors at the wafer-scale. A single etched silicon wafer contains an array of cavities containing alkali precursor materials offset laterally from the cell

Approximating the two-mode two-photon Rabi model

December 13, 2020
Author(s)
Victor Albert, David H. Wu
The Rabi model describes the simplest nontrivial interaction between a few-level system and a bosonic mode, featuring in multiple seemingly unrelated systems of importance to quantum science and technology. While exact expressions for the energies of this

Control Baselines for Information Systems and Organizations

December 11, 2020
Author(s)
Ronald S. Ross, Victoria Y. Pillitteri
This publication provides security and privacy control baselines for the Federal Government. There are three security control baselines (one for each system impact level: low-impact, moderate- impact, and high-impact), as well as a privacy baseline that is

Designing 3D printable cementitious materials with gel-forming polymers

December 11, 2020
Author(s)
Edward Garboczi, Hajar Taheri Afarani, William carroll, Joseph J. Biernacki
Cement based pastes for 3D printing applications were prepared using hydrogel-forming polymers. Preliminary results suggest that such gel-forming polymers can reduce the need for more complex admixture packages as printing aids. The influence of polymer

Full-Scale Experiments to Demonstrate Flammability Risk of Residential Upholstered Furniture and Mitigation Using Barrier Fabric

December 11, 2020
Author(s)
Mauro Zammarano, Matthew S. Hoehler, John R. Shields, Andre L. Thompson, Ickchan Kim, Isaac T. Leventon, Matthew F. Bundy
In this work, we investigated fire growth in a furnished compartment intended to mimic a living room where a couch was the main fuel load. Three TB-117-2013 compliant and commercially available couches were procured. The couches were identical except for

Object Measurements from 2D Microscopy Images

December 11, 2020
Author(s)
Peter Bajcsy, Joe Chalfoun, Mylene Simon, Mary C. Brady, Marcin Kociolek
This chapter addresses object measurements from 2D microscopy images. Object measurements (called image features) vary in terms of theoretical formulas for the same image feature, the physical units used to represent pixel-based measurements, the

Technical Language Processing: Unlocking Maintenance Knowledge

December 11, 2020
Author(s)
Michael P. Brundage, Thurston B. Sexton, Melinda Hodkiewicz, Alden A. Dima, Sarah Lukens
Out-of-the-box natural-language processing (NLP) pipelines need re-imagining to understand and meet the requirements of the engineering sector. Text-based documents account for a significant portion of data collected during the life cycle of asset

Towards Computing Resource Reservation Scheduling in Industrial Internet of Things

December 11, 2020
Author(s)
Fan Liang, Wei Yu, Xing Liu, David W. Griffith, Nada T. Golmie
The Industrial Internet of Things (IIoT) is a critically important implementation of the Internet of Things (IoT), connecting IoT devices ubiquitously in an industrial environment. Based on the interconnection of IoT devices, IIoT applications can collect

Unraveling the compositional heterogeneity and carrier dynamics of alkali cation doped 3D/2D perovskites with improved stability

December 11, 2020
Author(s)
Ming Chun Tang, Siyuan Zhang, Nhan V. Nguyen, Edwin J. Heilweil, Christina A. Hacker, Timothy J. Magnanelli, Thomas D. Anthopoulos
Preventing the degradation of hybrid perovskite by humid air remains a challenge for their future commercial utilization. 3D/2D perovskites with hierarchical architecture have attracted significant attention due to their promising power conversion

Comparison of primary laser spectroscopy and mass spectrometry methods for measuring mass concentration of gaseous elemental mercury

December 10, 2020
Author(s)
Abneesh Srivastava, Stephen E. Long, James E. Norris, Colleen E. Bryan Sallee, Jennifer Carney, Joseph Hodges
We present a direct comparison between two independent methods for the measurement of gaseous elemental mercury (GEM) mass concentration: isotope dilution cold-vapor inductively coupled plasma mass spectrometry (ID-CV-ICP-MS) and laser absorption

Security and Privacy Controls for Information Systems and Organizations

December 10, 2020
Author(s)
Ronald S. Ross, Victoria Y. Pillitteri
This publication provides a catalog of security and privacy controls for information systems and organizations to protect organizational operations and assets, individuals, other organizations, and the Nation from a diverse set of threats and risks

A Case Study for Modeling Machine Tool Systems Using Standard Representations

December 9, 2020
Author(s)
Maja V. Baerring, Guodong Shao, Moneer Helu, Bjorn Johansson
It is challenging to represent a complete machining tool system including geometric and kinematics information to support different decisions including purchasing, scheduling, and routing. A model of a fully assembled machining system in a neutral format

Hierarchical, grid-aware, and economically optimal coordination of distributed energy resources in realistic distribution systems

December 9, 2020
Author(s)
DJ Anand, Mads Almassalkhi, Sarnaduti Brahma, Nawaf Nazir, Hamid Ossareh, Pavan Racherla, Soumya Kundu, Sai Pushpak Nandanoori, Thiagarajan Ramachandran, Ankit Singhal, Dennice Gayme, Chengda Ji, Enrique Mallada, Yue Shen, Pengcheng You
Forward-looking renewable portfolio standards will lead to extreme levels of variable solar PV in electric distribution systems, which makes reliability more challenging to maintain for distribution system operators (DSOs). To facilitate reliability under

Lifetime-Limited Interrogation of Two Independent 27Al+ Clocks using Correlation Spectroscopy

December 9, 2020
Author(s)
Ethan Clements, May E. Kim, Kaifeng Cui, Aaron M. Hankin, Samuel M. Brewer, Jose Valencia, Jwo-Sy Chen, Chin-wen Chou, David Leibrandt, David Hume
Laser decoherence limits the stability of optical clocks by broadening the observable resonance linewidths and adding noise during the dead time between clock probes. Correlation spectroscopy avoids these limitations by measuring correlated atomic
