Light-induced fractional quantum hall phases in graphene

December 15, 2017
Author(s)
Michael Gullans, Areg Ghazaryan, Pouyan Ghaemi, Mohammad Hafezi
We show how to realize two-component fractional quantum Hall phases in monolayer graphene by optically driving the system. A laser is tuned into resonance between two Landau levels of graphene and acts as a e ective tunneling term between these states. We

Performance evolution of TLD-700H/600H dosimetry system at extended issue periods

December 15, 2017
Author(s)
Alexander A. Romanyukha, Matthew Grypp, F. Trompier, Alan Keith Thompson, Ronaldo Minniti, Jacque Debroas, Anthony S. Williams
Results of a comprehensive study of the TLD-700H/600H dosimetry system performance for an extended issue period are presented and discussed. It was concluded that the obtained results provide a technical justification to use the current dosimetry system at

The Influence of the Aromaticity in the Gas Chromatography Retention: The Case of Polycyclic Aromatic Sulfur Heterocycles

December 15, 2017
Author(s)
Jorge O. Ona-Ruales, Yosadara Ruiz-Morales, Fernando Alvarez-Ramirez, Walter Brent Wilson, Stephen A. Wise
The aromaticity has been used as a criterion to explain the GC retention of cata-condensed polycyclic aromatic sulfur heterocycles (PASHs) C12H8S, C16H10S, C20H12S; and peri-condensed PASHs C18H10S, in a GC column with 50% phenyl / 50% methyl silphenylene

The Text Recognition Algorithm Independent Evaluation (TRAIT)

December 15, 2017
Author(s)
Afzal A. Godil, Patrick J. Grother, Mei L. Ngan
The report describes and presents the results for text detection and recognition (TRAIT) evaluation in support of forensic investigations of digital media. These im- ages are of interest to NIST’s partner law enforcement agencies that seek to employ text

Normal-phase liquid chromatography retention behavior of polycyclic aromatic sulfur heterocycles (PASHs) and alkyl-substituted PASH isomers on an aminopropyl stationary phase

December 14, 2017
Author(s)
Walter B. Wilson, Hugh Hayes, Lane C. Sander, Andres Campiglia, Stephen A. Wise
Retention indices for 67 polycyclic aromatic sulfur heterocycles (PASHs) and 80 alkyl- substituted PASHs were determined using normal-phase liquid chromatography (NPLC) on a aminopropyl (NH2) stationary phase. The retention behavior of PASH on the NH2

Polar Codes for Quantum Key Distribution

December 14, 2017
Author(s)
Anastase Nakassis
This paper addresses the performance of polar codes in the context of the quantum key distribution (QKD) protocol. It introduces the notion of an interactive polar decoder and studies its performance. The results demonstrate that the interactive decoder is

Prospects for Magnetic Field Communications and Location Using Quantum Sensors

December 14, 2017
Author(s)
Vladislav P. Gerginov, Fabio C. Da Silva, David A. Howe
Signal attenuation limits the operating range in wireless communications and location. To solve the reduced range problem, one can use low-frequency signals in combination with magnetic sensing. We propose the use of an optically-pumped magnetometer as a

SHREC'17 Track: Point-Cloud Shape Retrieval of Non-Rigid Toys

December 14, 2017
Author(s)
Afzal A. Godil
In this paper, we present the results of the SHREC'17 Track: Point-Cloud Shape Retrieval of Non-Rigid Toys. The aim of this track is to create a fair benchmark to evaluate the performance of methods on the non-rigid point- cloud shape retrieval problem

A Method for Key Performance Indicator Assessment in Manufacturing Organizations

December 12, 2017
Author(s)
Patrick Hester, Barry Ezell, Andrew Collins, John A. Horst, Kaleen Lawsure
Key Performance Indicators (KPIs) are an essential element of an organization's ability to monitor its strategic health, helping to ensure the strategic goals of the organization are achieved. However, KPI assessment and improvement is often an ad hoc and

Relativistic theory of the falling retroreflector gravimeter

December 12, 2017
Author(s)
Neil Ashby
We develop a relativistic treatment of interference between light reflected from a falling cube retroreflector in the vertical arm of an interferometer, and light in a reference beam in the horizontal arm. Coordinates that are nearly Minkowskian, attached

Automatic Localization of Casting Defects with Convolutional Neural Networks

December 11, 2017
Author(s)
Ronay Ak, Max Ferguson, Yung-Tsun T. Lee, Kincho H. Law
Automatic localization of defects in metal castings is a challenging task, owing to the rare occurrence and variation in appearance of defects. Convolutional neural networks (CNN) have recently shown outstanding performance in both image classification and

Issues in Synthetic Data Generation for Advanced Manufacturing

December 11, 2017
Author(s)
Donald E. Libes, David Lechevalier, Sanjay Jain
Research into advanced manufacturing requires data for analysis. There is limited access to real-world data and a need for more data of varied types and larger quantity. This paper explores the issues, and identifies challenges, and suggests requirements
