The Metrological Basis for MOBY

December 20, 2018
Author(s)
Bettye C. Johnson
The Marine Optical BuoY (MOBY) is a primary source of data for System Vicarious Calibration (SVC) of ocean color satellite sensors. I will present brief introduction to SVC followed by a short history of MOBY and the main features of its instrumentation

Author(s)
Perry F. Wilson, Catherine A. Remley, William F. Young, Camillo A. Gentile, John M. Ladbury, Dylan F. Williams
The potential to connect people and devices anywhere and anytime is driving the development and deployment of a multitude of wireless systems. Wireless connectivity is central to advanced communication technologies, the internet of things (IoT), the smart

Platform Firmware Resiliency Guidelines

May 4, 2018
Author(s)
Andrew R. Regenscheid
This document provides technical guidelines and recommendations supporting resiliency of platform firmware and data against potentially destructive attacks. The platform is a collection of fundamental hardware and firmware components needed to boot and

Synthetic clock transitions via continuous dynamical decoupling

January 16, 2018
Author(s)
Ian B. Spielman, Nathan Lundblad, Ana Valdes-Curiel, Dimitrius Trypogeorgos
Decoherence of quantum systems due to uncontrolled fluctuations of the environment presents fundamental obstacles in quantum science. `Clock' transitions which are insensitive to such fluctuations are used to improve coherence, however, they are not

Hyperpolarizability and Operational Magic Wavelength in an Optical Lattice Clock

December 19, 2017
Author(s)
Roger C. Brown, Nate B. Phillips, Kyle P. Beloy, William F. McGrew, Marco Schioppo, Robert J. Fasano, Gianmaria Milani, Xiaogang Zhang, Nathan M. Hinkley, Holly F. Leopardi, T H. Yoon, Daniele Nicolodi, Tara M. Fortier, Andrew D. Ludlow
Optical clocks benefit from tight atomic confinement enabling extended interrogation times as well as Doppler- and recoil-free operation. However, these benefits come at the cost of frequency shifts that, if not properly controlled, may degrade clock

Impact of NIST Laboratory Outputs on Innovation

October 31, 2016
Author(s)
Gary W. Anderson Jr.
The National Institute of Standards and Technology’s (NIST) mission is to “promote U.S. innovation and industrial competitiveness.” To meet this mission, NIST scientists produce a great variety of scientific and technical outputs. This paper present

Workshop on Lunar Calibration for Remote Sensing

July 11, 2016
Author(s)
Claire E. Cramer
Tracking climate variables at the levels of precision and accuracy required to detect global change requires satellite sensors to make highly consistent measurements that can be compared to measurements made at different times and with different

Standards Landscape and Directions for Smart Manufacturing Systems

August 24, 2015
Author(s)
Yan Lu, Katherine C. Morris, Simon P. Frechette
The future of manufacturing lies in being able to adapt quickly to changing conditions. From smaller lot sizes, to more customization, to sudden changes in supply chain, the variability that manufacturers face is rapidly increasing. The key to enabling

SOLAR-WIND ION DRIVEN X-RAY EMISSION FROM COMETARY AND PLANETARY ATMOSPHERES: MEASUREMENTS AND THEORETICAL PREDICTIONS OF CHARGE- EXCHANGE CROSS SECTIONS AND EMISSION SPECTRA FOR O6+ + H2O, CO, CO2, CH4, N2, NO, N2O, AND Ar

August 15, 2015
Author(s)
J. R. Machacek, D. P. Mahapatra, David R. Schultz, Yuri Ralchenko, A. Moradmand, O. E. Ghazaly, A. Chutjian
Relevant to modeling and understanding X-ray emission from cometary and planetary atmospheres, total cross sections for 1.17 and 2.33 keV/u O6+ colliding with H2O, CO, CO2, CH4, N2, NO, N2O, and Ar have been measured for the processes of single, double

A Chemical Kinetic Mechanism for 2-Bromo-3,3,3-trifluoropropene (2-BTP) Flame Inhibition

July 22, 2015
Author(s)
Donald R. Burgess Jr., Valeri I. Babushok, Gregory T. Linteris, Jeffrey A. Manion
The present paper is concerned with the development of a detailed chemical kinetic mechanism to describe the flame inhibition chemistry of the fire suppressant 2-bromo-3,3,3-trifluoropropene (2-BTP). Currently 2-BTP is considered as a fire suppressant to

Uncertainty of nuclear counting

May 22, 2015
Author(s)
Stefaan Pomme, John Keightley, Ryan P. Fitzgerald
Nuclear counting is affected by pulse pileup and system dead time which induce rate-related count loss and alter the statistical properties of the counting process. Fundamental equations are presented to predict deviations from Poisson statistics due to

On the Unification of Access Control and Data Services

August 15, 2014
Author(s)
David F. Ferraiolo, Serban I. Gavrila, Wayne Jansen
A primary objective of enterprise computing (via a data center, cloud, etc.) is the controlled delivery of data services (DS). Typical DSs include applications such as email, workflow, and records management, as well as system level features, such as file

Fatigue Crack Growth Modeling of Pipeline Steels in High Pressure Gaseous Hydrogen

October 21, 2013
Author(s)
Robert L. Amaro, Elizabeth S. Drexler, Andrew J. Slifka
Hydrogen will likely play a key role in a future clean energy economy. However, fundamental understanding of the deleterious effects of hydrogen on the fatigue and fracture properties of pipeline steels is lacking. Furthermore, engineering tools for design

Surface science for improved ion traps

September 30, 2013
Author(s)
David P. Pappas, Dustin Hite, Andrew C. Wilson, David T. Allcock, David J. Wineland, Dietrich Leibfried, Yves Colombe
Trapped ions are sensitive to electric-field noise from trap-electrode surfaces. This noise has been an obstacle to progress in trapped-ion quantum information processing (QIP) experiments for more than a decade. It causes motional heating of the ions, and

Effectively Control Negative Thermal Expansion of Single-phase Ferroelecrics of PbTiO 3 -(Bi,La)FeO 3 over a Giant Range

August 16, 2013
Author(s)
Jun Chen, Fangfang Wang, Qingzhen Huang, Lei Hu, Xiping Song, Jinxia Deng, Ranbo Yu, Xianran Xing
Control of negative thermal expansion is a fundamentally interesting topic in the negative thermal expansion materials in order for the future applications. However, it is a challenge to control the negative thermal expansion in individual pure materials

Adhesion Society Meeting Proceedings

Rebecca Ploeger, Aaron Forster, Donald Hunston, Etienne de la Rie, Christopher McGlinchey
Consolidating adhesives have been used throughout the centuries for the conservation of painted cultural objects- such as paintings and polychrome sculpture- and if it were not for these adhesives, many objects may not have survived to the present day

The New Golden Age of Algorithms and Data Structures

October 29, 2012
Author(s)
Paul E. Black
Before 1976 Communications of the ACM printed (and numbered!) new algorithms every issue. Quicksort was invented in 1960, Boyer-Moore string search in 1977, and combsort in 1980. I haven't seen a new, general sorting algorithm in over a decade. The latest
