Physical Model for Random Telegraph Noise Amplitudes and Implications

June 12, 2012
Author(s)
Richard G. Southwick, Kin P. Cheung, Jason P. Campbell, Serghei Drozdov, Jason T. Ryan, John S. Suehle, Anthony Oates
Random Telegraph Noise (RTN) has been shown to surpass random dopant fluctuations as a cause for decananometer device variability, through the measurement of a large number of ultra-scaled devices [1]. The most worrisome aspect of RTN is the tail of the

Guide to Bluetooth Security

Author(s)
John Padgette, Lidong Chen, Karen Scarfone
[Superseded by SP 800-121 Rev. 2 (May 2017): http://www.nist.gov/manuscript-publication- search.cfm?pub_id=922974] Bluetooth is an open standard for short-range radio frequency communication. Bluetooth technology is used primarily to establish wireless

High Confidence Level Calibration for AFM Based Fracture Testing of Nanobeams

June 11, 2012
Author(s)
Scott Grutzik, Richard S. Gates, Yvonne B. Gerbig, Robert F. Cook, Melissa Hines, Alan Zehnder
When designing micro- or nanoelectromechanical systems, (MEMS and NEMS), it is important to consider whether structural elements will withstand loads experienced during operation. Fracture behavior at length scales present in MEMS and NEMS is much di erent

Propagation and control of nano-scale, magnetic droplet solitons

June 11, 2012
Author(s)
Thomas J. Silva, Mark Hoefer, Matteo Sommacal
The propagation and controlled manipulation of strongly nonlinear, two-dimensional solitonic states in a thin, anisotropic ferromagnet is theoretically demonstrated. It has been recently proposed that spin polarized currents in a nanocontact device could

Simulation-based Approaches to Studying Effectiveness of Moving-Target Network Defense

June 11, 2012
Author(s)
Rui Zhuang, Su Zhang, Scott DeLoach, Xinming Ou, Anoop Singhal
Moving-target defense has been hypothesized as a potential game changer in cyber defense, including that for computer networks. However there has been little work to study how much proactively changing a network's configuration can increase the difficulty

Tensile behavior of single PPTA fibers measured by the Kolsky bar using the direct fiber clamping method

June 11, 2012
Author(s)
Jae Hyun Kim, Nathanael A. Heckert, Stefan D. Leigh, Haruki Kobayashi, Walter G. McDonough, Richard L. Rhorer, Kirk D. Rice, Gale A. Holmes
The Kolsky bar test has been widely used in measuring material behavior under high strain rate conditions. In particular, this methodology has been used to characterize the high strain rate behavior of polymer and polymer composites during ballistic impact

The Internet of Things: A Reality Check

June 11, 2012
Author(s)
George Hurlburt, Jeff Voas, Keith Miller
The short persepctive explains the concept behind Internet of Things (IoT). The publication is a perspectives piece for an IEEE magazine and not intended to be technical. This is intended to be published in a specific column in the magazine.

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
