ThermoData Engine (TDE) Version 7.0 (Pure compounds, Binary Mixtures, Ternary Mixtures, Chemical Reactions) Standard Reference Database 103b

June 11, 2012
Author(s)
Michael D. Frenkel, Robert D. Chirico, Vladimir Diky, Chris D. Muzny, Andrei F. Kazakov, Joe W. Magee, Ilmutdin M. Abdulagatov, Kenneth G. Kroenlein, Carlos A. Diaz-Tovar, Jeong W. Kang, Rafiqul Gani
The first full-scale software implementation of the dynamic data evaluation concept {ThermoData Engine (TDE)} is described for thermophysical and thermochemical property data. This concept requires the development of large electronic databases capable of

Towards a fiber-coupled picowatt cryogenic radiometer

June 11, 2012
Author(s)
Nathan A. Tomlin, John H. Lehman, Sae Woo Nam
A picowatt cryogenic radiometer (PCR) has been fabricated at the microscale level for electrical substitution optical fiber power measurements. The absorber, electrical heater, and thermometer are all on a micromachined membrane less than 1mm on a side

Channel Length-Dependent Series Resistance?

June 10, 2012
Author(s)
Jason P. Campbell, Kin P. Cheung, Serghei Drozdov, Richard G. Southwick, Jason T. Ryan, Tony Oates, John S. Suehle
A recently developed series resistance (RSD) extraction procedure from a single nanoscale device is shown to be highly robust. Despite these virtues, the technique unexpectedly results in a channel length-dependent RSD which is observed across a wide range

Parametric uncertainty in nanoscale optical dimensional measurements

June 10, 2012
Author(s)
James E. Potzick, Egon Marx
Image modeling establishes the relation between an object and its image when an optical microscope is used to measure the dimensions of an object of size comparable to the illumination wavelength. It accounts for the influence of all of the parameters

An Assessment of the Accuracy of Automatic Evaluation in Summarization

June 8, 2012
Author(s)
Karolina K. Owczarzak, John M. Conroy, Hoa T. Dang, Ani Nenkova
Automatic evaluation has greatly facilitated system development in summarization. At the same time, the use of automatic evaluation has been viewed with mistrust by many, as its accuracy and correct application are not well understood. In this paper we

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
