Designing a Cyber-Physical Cloud Computing Architecture

June 2, 2015
Author(s)
Eric D. Simmon, Sulayman Sowe, Koji Zettsu
In this era of inter-connectivity where almost everybody, everything, and anything are networked, Cyber-Physical Systems (CPS) also known as the Internet of Things (IoT) have emerged as vital systems that use information systems to observe and modify the

Impact of Decision and Allocation Rules on Selection Decisions

June 2, 2015
Author(s)
Dennis D. Leber, Jeffery W. Herrmann
The quality of a selection decision is a function of the decision rule used and the data collected to support the decision. When physical measurements are the basis of the decision data, the measurement sampling scheme controls measurement uncertainty and

Internal Magnetic Structure of Nanoparticles Dominates Time-Dependent Relaxation Processes in a Magnetic Field

June 2, 2015
Author(s)
Cindi L. Dennis, Kathryn L. Krycka, Julie Borchers, Ryan D. Desautels, Johan van Lierop, Natalie F. Huls, Andrew J. Jackson, Cordula Gruettner, Robert Ivkov
Time-dependent relaxation of nanomagnets, such as magnetic nanoparticles, have applications in many disciplines of science and technology because these magnets can exhibit hysteresis and loss power when exposed to AC magnetic fields. In particular, the

Nanometer level sampling and control of a scanning electron microscope

June 2, 2015
Author(s)
Bradley N. Damazo, Andras Vladar, Olivier M. Marie-Rose, John A. Kramar
The National Institute of Standards and Technology (NIST) is developing a specialized, metrology scanning electron microscope (SEM), having a metrology sample stage measured by a 38 picometer resolution, high-bandwidth laser interferometer system. The

Superconducting Transition Edge Sensors for Quantum Optics

June 2, 2015
Author(s)
Thomas Gerrits, Adriana E. Lita, Brice R. Calkins
High efficiency single-photon detectors allow novel measurements in quantum information processing and quantum photonic systems. The photon-number resolving transition edge sensor (TES) is known for its near-unity detection efficiency and has been used in

COMMON SPURIOUS SIGNALS OBSERVED IN MASS SPECTROMETERS

June 1, 2015
Author(s)
Thomas J. Bruno, Paris D. Svoronos-Cambanas
The following table provides guidance in the recognition and interpretation of spurious signals (m/z peaks) that will sometimes be observed in mass spectra, especially mass spectra obtained from gas chromatography mass spectrometry systems (GC-MS) [1,2]

Dimensionless units in the SI

June 1, 2015
Author(s)
Peter J. Mohr, William D. Phillips
The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider dimensionless units as defined in the SI, e.g. angular

Dynamic 3D Visualizations of Complex Function Surfaces Using X3DOM and WebGL

June 1, 2015
Author(s)
Bonita V. Saunders, Brian Antonishek, Qiming Wang, Bruce R. Miller
In 1997 the National Institute of Standards and Technology (NIST) embarked on a huge project to replace one of the most cited resources for mathematical, physical and engineering scientists, the Handbook of Mathematical Functions with Formulas, Graphs, and

Evaluation of Uncertainty in Temporal Waveforms of Microwave Transistors

June 1, 2015
Author(s)
Gustavo Avolio, Antonio Raffo, Jeffrey Jargon, Dominique Schreurs, Dylan Williams
This work focuses on the accuracy of nonlinear de-embedding applied to microwave transistor time-domain waveforms. The waveforms are acquired with a mixer-based Large-Signal Network Analyzer (LSNA) and are corrected at the transistor's reference planes by

Fiber Bragg Gratings Embedded in 3D-Printed Scaffolds

June 1, 2015
Author(s)
Peter Liacouras, Khazar Choudhry, Grant Grant, Gregory F. Strouse, Zeeshan Ahmed
In recent years there has been considerable interest in utilizing fiber optic based sensors as embedded sensor for fabricating smart materials. One of the primary motivations is to provide real-time information on the structural health of the material so
