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

Progress Report National Institute of Standards and Technology (NIST); Technical Investigation of the May 22, 2011, Tornado in Joplin, Missouri (NISTSP 1139)

November 15, 2012
Author(s)
Erica D. Kuligowski, Franklin T. Lombardo, Long Phan, Marc L. Levitan, David P. Jorgensen
On June 29, 2011, the National Institute of Standards and Technology (NIST) announced that it would conduct a technical investigation of the tornado that struck Joplin, MO, on May 22, 2011. In November 2011, NIST released a draft plan for the study and

Tentative Framework for Development of Advanced Seismic Design Criteria for New Buildings

November 15, 2012
Author(s)
Charles Kircher, Finley Charney, Gregory Deierlein, James Harris, William Holmes, John Hooper, Laura Lowes
During the conduct of the ATC-63 Project, which was funded by the Federal Emergency Management Agency (FEMA) and resulted in the publication of the FEMA P-695 report, Quantification of Building Seismic Performance Factors (FEMA, 2009), it became apparent

Third-Round Report of the SHA-3 Cryptographic Hash Algorithm Competition

November 15, 2012
Author(s)
Shu-jen H. Chang, Ray A. Perlner, William E. Burr, Meltem Sonmez Turan, John M. Kelsey, Souradyuti Paul, Lawrence E. Bassham
The National Institute of Standards and Technology (NIST) opened a public competition on November 2, 2007 to develop a new cryptographic hash algorithm - SHA-3, which will augment the hash algorithms specified in the Federal Information Processing Standard

Toward Better Integration of Vehicle Assembly Production Systems

November 15, 2012
Author(s)
Jorge Arinez, John L. Michaloski, Frederick M. Proctor, William G. Rippey, C J. Yen
In today's manufacturing world, system integration often necessitates composing systems of technology that are not designed to interoperate with each other. This inherent incompatibility results in redundant, non-value added work that is required for

Chirality-controlled cloning of carbon nanotubes

November 13, 2012
Author(s)
Ming Zheng, Xiaomin X. Tu, Jia Liu, Chuan Wang, Chongwu Zhou
Carbon nanotubes possess superior electrical and optical properties and hold great promise for electronic and biomedical applications1-10. The electronic properties of carbon nanotubes strongly depend on their chirality, with 1/3 being metallic1, 2/3 being

Vibrational modes of GaN nanowires in the gigahertz range

November 13, 2012
Author(s)
Ward L. Johnson, Sudook A. Kim, Roy H. Geiss, Colm Flannery, Kristine A. Bertness, Paul R. Heyliger
Monocrystalline nanowires offer an attractive basis for resonant nanoelectromechanical systems (NEMS) for a variety of applications, including mass and force sensing, and, in each of these applications, there are advantages to operation at frequencies

Ultra-low noise regenerative frequency divider

November 11, 2012
Author(s)
Archita Hati, Craig W. Nelson, Corey A. Barnes, Danielle G. Lirette, Jason A. DeSalvo, David A. Howe
We designed ultra-low noise regenerative divider-by-2 circuits that operate at input frequencies of 20 MHz and 10 MHz. We achieved residual output-referred single-sideband phase noise below -162 dBc/Hz at 10 Hz offset for a single divider at these

Bridging the gap between random microstructure and 3-D meshing

November 10, 2012
Author(s)
Edward Garboczi, Yang Lu
There are different ways of mathematically representing 3-D heterogeneous material structures. But for each of these methods, usually the desired end result is a 3-D finite element mesh that will be used to investigate the mechanical properties of the

Testing the Nations Health care Information Infrastructure

November 10, 2012
Author(s)
Kevin G. Brady, Ram D. Sriram, Bettijoyce B. Lide, Kathleen M. Roberts
According to a report by the Center for Medicare and Medicaid Services [CMS] (http://www.cms.gov), the United States spent nearly $2.6 trillion dollars on health care in 2010. It is estimated that this will nearly double by the end of this decade. This is

Electronic structure of Ba-Ga-Ge-Si Type I Clathrates: A Ge and Ga K-Edge Study

November 9, 2012
Author(s)
Winnie Wong-Ng, Azzam Mansour, Joshua Martin, George S. Nolas
XANES spectroscopy was successfully used to study changes in the density of unoccupied states for silicon substituted Ba8Ga16Ge30-xSix type I clathrates. Partial density of unoccupied states with p character is modified for both Ga and Ge upon Si

Fast Sequential Importance Sampling to Estimate the Graph Reliability Polynomial

November 8, 2012
Author(s)
David G. Harris, Francis Sullivan, Isabel M. Beichl
The reliability polynomial of a graph measures the number of its connected subgraphs of various sizes. Algortihms based on sequential importance sampling (SIS) have been proposed to estimate a graph's reliahbility polynomial. We develop an improved SIS
