Correction of Optical Aberrations in Elliptic Neutron Guides

November 21, 2012
Author(s)
Phllip M. Bentley, Shane J. Kennedy, Ken H. Andersen, Damian Martin Rodriguez, David F. Mildner
Modern, nonlinear ballistic neutron guides are an attractive concept in neutron beam delivery and instrumentation, because they offer increased performance over straight or linearly tapered guides. However, like other ballistic geometries they have the

Magnetic Order and Fluctuations in the Presence of Quenched Disorder in the Kagome Staircase System (Co 1-x Mg x ) 3 V 2 O 8

November 21, 2012
Author(s)
K. Fritsch, Zahra Yamani, S. Chang, Yiming Qiu, John R. Copley, M. Ramazanoglu, H. A. Dabkowska, B. D. Gaulin
Co 3V 2O 8 is an orthorhombic magnet in which S=3/2} magnetic moments reside on two crystallographically inequivalent Co 2+ sites, which decorate a stacked, buckled version of the two dimensional kagome lattice, the stacked kagome staircase. The magnetic

A frequency-bandgap waveguide controlled with metafilms composed of cubic particles

November 20, 2012
Author(s)
Sung Kim, Christopher L. Holloway, Michael D. Janezic, Kendra L. Kumley, James R. Baker-Jarvis, Edward Kuester
We present a rectangular S-band waveguide having electromagnetic bandgap properties (stopbands) controlled with sheets of metafilms composed of ceramic particles, in which we present both analytic and experimental results. Metafilms composed of TiO("d)2

A Grassmann Manifold-based Domain Adaptation Approach

November 20, 2012
Author(s)
P J. Phillips, Jingjing Zheng, Ming-Yu Liu, Rama Chellappa
Domain adaptation algorithms that handle shifts in the distribution between training and testing data are receiving much attention in computer vision. Recently, a Grassmann manifold-based domain adaptation algorithm that models the domain shift using

Smart Networked Systems and Societies: Research Challenges

November 20, 2012
Author(s)
Ram D. Sriram
We are witnessing a new revolution in computing and communication. The Internet, which has spanned several networks in a wide variety of domains, is having a significant impact on every aspect of our lives. The next generation of networks will utilize a

The Good, the Bad, and the Ugly Face Challenge Problem

November 20, 2012
Author(s)
P J. Phillips, J. R. Beveridge, Bruce A. Draper, Geof H. Givens, Alice J. O'Toole, David Bolme, Joseph Dunlop, Yui M. Lui, Hassan A. Sahibzada, Samuel Weimer
The Good, the Bad, & the Ugly Face Challenge Problem was created to encourage the development of algorithms that are robust to recognition across changes that occur in still frontal faces. The Good, the Bad, & the Ugly consists of three partitions. The

Absolute line intensities for ethylene from 1800 to 2350 cm-1.

November 17, 2012
Author(s)
Walter J. Lafferty, Jean-Marie Flaud, A. Ben Hassen, F. K. Kwabia Tchana, X Landsheere, H Aroui
Fourteen Fourier transform spectra of ethylene (C2H4) have been recorded in the 1800-2350 spectral domain with different path-lengths and pressures and used to derive individual line intensities for lines belonging to the ν7 + ν8, ν4 + ν8 , ν6 + ν10, ν6 +

Capillary Wave Dynamics of Thin Polymer films over Submerged Nanostructures

November 16, 2012
Author(s)
Christopher L. Soles, Hyun W. Ro, K. J. Alvine, Oleg Shpyrko, Yenling Dai, Alec Sandy, Suresh Narayanan
The surface dynamics of thin molten polystyrene films supported by nanoscale periodic silicon line-space gratings were investigated with X-ray photon correlation spectroscopy. Surface dynamics over these nanostructures exhibit high directional anisotropy

A Reference Modulated Scatterer for ISO18000-6 UHF Tag Testing

November 15, 2012
Author(s)
David R. Novotny, Daniel G. Kuester, Jeffrey R. Guerrieri
We present a method for measuring Ultra-High Frequency Radio-Frequency Identification (UHF RFID) tag differential RCS that has the potential for being easier and more accurate than current and proposed methods [1-2]. This method is based on accurately

A Sensor Model for Enhancement of Manufacturing Equipment Data Interoperability

November 15, 2012
Author(s)
Kang B. Lee, Yuyin Song, Peter S. Gu
Sensors can provide real-time production information to optimize manufacturing activities in a factory. Recently, more attention has been paid to the application of sensors in smart manufacturing systems. Sensor data exchange, sharing, and interoperability

Baseband Voltage and Power in Load-Modulated Digital Backscatter

November 15, 2012
Author(s)
Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri, Zoya Popovic
Passive digital backscatter signals in systems like radio frequency identification (RFID) are usually received along with strong interference from a leaked carrier. The simplest way to quantify the “useful” communication signal is to separate an amplitude

High-resolution infrared studies of the V10, V11, V14, and V18 levels of [1.1.1] propellane

November 15, 2012
Author(s)
Robynne Kirkpatrick, Tony Masiello, Mathew A. Martin, Joseph W. Nibler, Arthur Maki, Alfons Weber, Thomas A. Blake
This paper is a continuation of earlier work for which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transitions
