Siamak Sattar, Therese P. McAllister, Katherine J. Johnson, Christopher T. Clavin, Christopher L. Segura, Steven L. McCabe, Juan F. Fung, Leslie Abrahams, Emily Sylak-Glassman , Marc L. Levitan, Kenneth W. Harrison, John L. Harris
The performance of buildings in our communities depends on multiple factors including the availability of supporting infrastructure, the original design, the current condition and capacity to resist hazard impacts, and the ability to recover functionality

The Effects of Laser Powder Bed Fusion Process Parameters on Material Hardness and Density for Nickel Alloy 625

August 21, 2018
Author(s)
Christopher U. Brown, Gregor Jacob, Antonio M. Possolo, Carlos R. Beauchamp, Max A. Peltz, Mark R. Stoudt, M A. Donmez
The goal of this study was to investigate the relationship between mechanical and material properties (including density) of manufactured nickel super alloy (IN625) using a laser powder bed fusion process and three process parameters: laser power, hatch

White Rabbit-Based Time Distribution at NIST

August 21, 2018
Author(s)
Joshua J. Savory, Jeffrey A. Sherman, Stefania Romisch
The National Institute of Standards and Technology (NIST) is responsible for ensuring the quality of its international and domestic time and frequency distribution systems. Since the physical inputs to these systems are not collocated within the campus, an

Bubble-Point Measurements and Modeling of Binary Mixtures of Linear Siloxanes

August 20, 2018
Author(s)
Luuc Keulen, Elisabeth Mansfield, Ian Bell, Andrea Spinelli, A. Guardone
The bubble-point pressures of three binary mixtures of linear siloxanes have been mea4 sured. The binary mixtures consist of hexamethyldisiloxane (MM) which is mixed with ei5 ther octamethyltrisiloxane (MDM), decamethyltetrasiloxane (MD2M), and

Fe 2 MnGe: A Hexagonal Heusler Analogue

August 20, 2018
Author(s)
S. Keshavarz, N. Naghibolashrafi, Michelle E. Jamer, K. Vinson, D. Mazumdar, Cindi L. Dennis, William D. Ratcliff, Julie Borchers, A. Gupta, P. LeClair
Fe 2MnGe is a potential half-metallic full-Heusler L2 1 ferromagnetic compound with large spin polarization (approximately equal}97%) useful for various spintronic applications according to our first principles calculations using density functional theory

Securing Wireless Infusion Pumps in Healthcare Delivery Organizations

August 20, 2018
Author(s)
Gavin W. O'Brien, Sallie Edwards, Kevin Littlefield, Neil McNab, Sue Wang, Kangmin Zheng
Medical devices, such as infusion pumps, were once standalone instruments that interacted only with the patient or medical provider. However, today’s medical devices connect to a variety of healthcare systems, networks, and other tools within a healthcare

Towards a Platform for Smart Manufacturing Improvement Planning

August 20, 2018
Author(s)
Boonserm Kulvatunyou, Sangsu Choi, Thorsten Wuest
The manufacturing industry is transitioning towards smart manufacturing systems (SMS). Small and medium size manufacturers (SMMs) are particularly be-hind in this transition, plagued by lack of knowledge and resources. Several smart manufacturing

Bottom-up Filling of Damascene Trenches with Gold in a Sulfite Electrolyte

August 19, 2018
Author(s)
Daniel Josell, Thomas P. Moffat
Superconformal Au deposition is demonstrated in a Na3Au(SO3)2 + Na2SO3 electrolyte including Bi3+. Micromolar additions of the Bi3+ to the electrolyte catalyze the reduction of Au(SO3)23- based on hysteretic voltammetry and rising chronoamperometric

Condition-based Real-time Production Control for Smart Manufacturing Systems

August 19, 2018
Author(s)
Yan Lu, Feifan Wang, Feng Ju
In this paper, we present condition-based real-time production control for smart manufacturing which is aimed at improving system performance by automatically assessing a production system's condition and dynamically configuring the processing routes for

Pseudorandom Quantum States

August 19, 2018
Author(s)
Yi-Kai Liu, Zhengfeng Ji, Fang Song
We propose the concept of pseudorandom quantum states, which appear random to any quantum polynomial-time adversary. It offers a computational approximation to perfectly random quantum states (analogous to cryptographic pseudorandom generators), as opposed

Methane Storage in Paddlewheel-Based Porous Coordination Cages

August 18, 2018
Author(s)
Casey A. Rowland, Gregory R. Lorzing, Eric J. Gosselin, Benjamin Trump, Glenn P. A. Yap, Craig Brown, Eric D. Bloch
Although gas adsorption properties of extended three-dimensional metal-organic materials have been widely studied, they remain relatively unexplored in porous molecular systems. This is particularly the case for porous coordination cages which typically

Cryogenic Primary Standard for Optical Fibre Power Measurement

August 17, 2018
Author(s)
Malcolm G. White, Zeus Ruiz, Christopher S. Yung, Igor Vayshenker, Nathan A. Tomlin, Michelle S. Stephens, John H. Lehman
NIST has completed commissioning a new, state-of-the-art cryogenic primary standard for optical fibre power measurement and calibration. It establishes for the first time, a direct traceability route between the device under test and primary standard. Two

Influence of wind tunnel test duration on wind load factors

August 17, 2018
Author(s)
Dat Duthinh, Adam L. Pintar, Emil Simiu
A methodology is presented for calculating the uncertainty associated with the estimation of peak pressure coefficients from wind tunnel test records of various lengths, and how this uncertainty affects design wind effects. Investigation of time series

Optical Properties of Meloxicam in the Far-Infrared Spectral Region

August 17, 2018
Author(s)
Yusuf S. Aytekin, Mustafa Koturk, Adam Zaczek, Timothy M. Korter, Edwin J. Heilweil, Okan Esenturk
One of the most commonly used nonsteroidal anti-inflammatory active pharmaceutical ingredient called Meloxicam has been characterized spectroscopically both by Terahertz (THz) time domain spectroscopy (THz-TDS) and by Fourier Transform Infrared (FTIR)
