Assessing the Effect of Inconsistent Assessors on Summarization Evaluation

June 8, 2012
Author(s)
Karolina K. Owczarzak, Peter Rankel, Hoa T. Dang, John M. Conroy
We investigate the consistency of human assessors involved in summarization evaluation to understand its effect on system ranking and automatic evaluation techniques. Using Text Analysis Conference data, we measure annotator consistency based on human

Detection of Cutting Phenomena Using Sensor Fusion

June 8, 2012
Author(s)
John A. Slotwinski, Gregory W. Vogl, Robert W. Ivester, Ian Younker
This paper presents an investigation of the application of a suite of sensors for simultaneous in-situ measurements of machining processes. While not every individual sensor responds to all machining phenomena, the suite of sensors together responds to

Enabling Machining Vision Using STEP-NC

June 8, 2012
Author(s)
Martin Hardwick, Frederick M. Proctor, David Loffredo, Sid Venkatesh
STEP-NC is a new data format for manufacturing control. One of its applications is to enable integrated on machine measurement of machining processes using vision systems and other sensors. In this paper we describe the manufacturing process and

Preparation and Measurement Methods for Studying Nanoparticle Aggregate Surface Chemistry

June 8, 2012
Author(s)
Christopher W. Szakal, James McCarthy, Andrew R. Konicek, Kacie Louis, Benjamin Yezer, Andrew A. Herzing, Robert Hamers, Richard D. Holbrook
Despite best efforts at controlling nanoparticle (NP) surface chemistries, the environment surrounding nanomaterials is always changing and can impart a permanent chemical memory. We present a set of preparation and measurement methods to be used as the

Synthesis of Manufacturing and Facility Data for Sustainability Analysis

June 8, 2012
Author(s)
John L. Michaloski, Guodong Shao, Swee K. Leong, Frank H. Riddick, Jonatan Berglund, Jorge Arinez, Stephan Biller
This paper discusses data synthesis of production and facility knowledge for sustainability analysis by applying the ISA 95 "Activity Models of Manufacturing Operations Management" (MOM) model. Presently, production and facility management are "silo"

Certification of SRM 2492: Bingham Paste Mixture for Rheological Measurements

June 7, 2012
Author(s)
Chiara F. Ferraris, Paul E. Stutzman, William F. Guthrie
Rheological measurements are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating [1]. Usually, the angular velocity is imposed and the response of the material

Sub-femtosecond absolute timing jitter with a 10 GHz hybrid photonic-microwave oscillator

June 7, 2012
Author(s)
Tara M. Fortier, Craig W. Nelson, Archita Hati, Franklyn J. Quinlan, Jennifer A. Taylor, Haifeng (. Jiang, Chin-Wen Chou, Till P. Rosenband, Nathan D. Lemke, Andrew D. Ludlow, David A. Howe, Christopher W. Oates, Scott A. Diddams
We present an optical-electronic approach to generating microwave signals with high spectral purity. By overcoming shot noise and operating near fundamental thermal limits, we demonstrate 10 GHz signals that have timing deviation from an ideal periodic

The Benefits of U.S.-European Security Standardization

June 6, 2012
Author(s)
Erik Puskar
This paper briefly characterizes the benefits of collaboration, focusing on the innovations and efficiencies that standardization entails. EU-U.S. standization institutions and collaborative standardization initiative are identified; the logic of expanding

The non-Abelian Duality Problem

June 6, 2012
Author(s)
Emanuel H. Knill, E. Cobanera, Gerardo Ortiz
We exploit a new theory of duality transformations to construct dual representations of models incompatible with traditional duality transformations. Hence we obtain a solution to the long-standing problem of non-Abelian dualities that hinges on two key

Two-dimensional transport and screening in topological insulator surface states

June 6, 2012
Author(s)
Shaffique Adam, Euyheon Hwang, Sankar Das Sarma
We study the surface states of Bi2Se3 close to the topologically protected crossing point. Close to charge neutrality, local fluctuations in carrier density result in electron and hole puddles that dominate the electronic properties of these materials. By

Dimensional Metrology for Micro/Meso-Scale Manufacturing

June 5, 2012
Author(s)
Shawn P. Moylan
The small sizes, range of shapes and sizes, and low absolute tolerances present unique challenges to geometric dimensional metrology at the micro/meso-scale. This chapter provides and overview of the most common methods used for geometric dimensional

Synthetic 3D Spin-Orbit Coupling

June 5, 2012
Author(s)
Ian B. Spielman, Brandon Anderson, Gediminas Juzeliunas, Victor Galitski
We describe a method for creating a three-dimensional analogue to Rashba spin-orbit coupling in systems of ultracold atoms. This laser induced coupling uses Raman transitions to link four internal atomic states with a tetrahedral geometry, and gives rise

Three-dimensional real-time tracking of nanoparticles at an oil-water interface

June 5, 2012
Author(s)
Kan K. Du, James A. Liddle, Andrew J. Berglund
We show that real-time feedback control can be used to study three-dimensional nanoparticle transport dynamics. We apply the method to study the behavior of adsorbed nanoparticles at a silicone oil-water interface in a microemulsion system over a range of

Traffic Scheduling Technique for Smart Grid Advanced Metering Applications

June 5, 2012
Author(s)
Hamid Gharavi
In this paper, we present a multi-gate mesh network architecture that has been developed to ensure high performance and reliability under emergency conditions when a system expects to receive power outage notifications and exchanges. In order to handle the

Calibration of an Astrophysical Spectrograph below 1 m/s using a Laser Frequency Comb

June 4, 2012
Author(s)
David F. Phillips, Alexander G. Glenday, Chih-hao Li, Claire E. Cramer, Gabor Furesz, Guoquing Chang, Andrew Benedick, Li-Jin Chen, F X. Kaertner, Sylvain G. Korzennik, Dimitar Sasselov, Andrew Szentgyorgyi, Ronald L. Walsworth
We deployed two wavelength calibrators based on laser frequency combs ("astro-combs") at an astronomical observatory. One astro-comb operated over a 100 nm band in the deep red ( 800 nm) and a second operated over a 20 nm band in the blue ( 400 nm). We

Effect of Losses on the Performance of an SU(1,1) Interferometer

June 4, 2012
Author(s)
Alberto M. Marino, Neil V. Corzo Trejo, Paul D. Lett
We study the effect of losses on the phase sensitivity of the SU(1,1) interferometer for different configurations. We find that this type of interferometer is robust against losses that result from an inefficient detection system. This type of loss only

Evaluation of Fault Detection Effectiveness for Combinatorial and Exhaustive Selection of Discretized Test Inputs
