Modeling the effects of acid amplifiers on photoresist stochastics

March 23, 2012
Author(s)
Gregg M. Gallatin, Patrick Naulleau, Robert Brainard
The tradeoff between Resolution, Line Edge Roughness (LER) and Sensitivity, the so called RLS tradeoff, continues to be a difficult challenge, especially for EUV lithography. Acid amplifiers have recently been proposed as a method to improve upon the

Author(s)
Jeremy Marvel, Tsai H. Hong, Elena R. Messina
The 2011 Solutions in Perception Challenge (SPC) presented an international collection of teams with the opportunity to develop algorithms that could positively identify and accurately locate in space an arbitrary collection of artifacts. Researchers at

A Keyed Sponge Construction with Pseudorandomness in the Standard Model

March 22, 2012
Author(s)
Donghoon Chang, Morris Dworkin, Seokhie Hong, John M. Kelsey, Mridul Nandi
The sponge construction, designed by Bertoni, Daemen, Peeters, and Asscheis, is the framework for hash functions such as Keccak, PHOTON, Quark, and spongent. The designers give a keyed sponge construction by prepending the message with key and prove a

Julien M. Amelot, YaShian Li-Baboud, Clement Vasseur, Jeffrey Fletcher, Dhananjay Anand, James Moyne
The numerous time synchronization performance requirements in the Smart Grid entails the need for a set of common metrics and test methods to verify the ability of the network system and its components to meet the power industry�s accuracy, reliability and

Development of Ballistics Identification - From Image Comparison to Topography Measurement in Surface Metrology-

March 22, 2012
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Robert M. Thompson, Thomas Brian Renegar, Xiaoyu Alan Zheng, James H. Yen, Richard M. Silver, Wei Chu
Fired bullets and ejected cartridge cases have unique ballistics signatures left by the firearm. By analyzing the ballistics signatures, forensic examiners can trace these bullets and cartridge cases to the firearm used in a crime scene. Current automated

Emergency Response Robot Evaluation Exercise

March 22, 2012
Author(s)
Adam S. Jacoff, Hui-Min Huang, Ann Virts, Anthony Downs, Raymond Sheh
More than 60 robot test methods are being developed by a team lead by the National Institute of Standards and Technology (NIST) with the sponsorship of U.S. Department of Homeland Security (DHS). These test methods are being specified and standardized

Functional Requirements of a Model for Kitting Plans

March 22, 2012
Author(s)
Stephen B. Balakirsky, Zeid Kootbally, Thomas R. Kramer, Rajmohan Madhavan, Craig I. Schlenoff, Michael O. Shneier
Industrial assembly of manufactured products is often performed by first bringing parts together in a kit and then moving the kit to the assembly area where the parts are used to assemble products. Kitting, the process of building kits, has not yet been

Improved Indifferentiability Security Bound for the JH Mode

March 22, 2012
Author(s)
Dustin Moody, Souradyuti Paul, Daniel C. Smith-Tone
The JH hash function is one of the five fi nalists of the ongoing NIST SHA3 hash function competition. Despite several earlier attempts, and years of analysis, the indi fferentiability security bound of the JH mode has so far remained remarkably low, only

Infrared detector calibrations

March 22, 2012
Author(s)
George P. Eppeldauer, Vyacheslav B. Podobedov
An InSb working standard radiometer, first calibrated at NIST in 1999 against a cryogenic bolometer, was recently calibrated against a newly developed low-NEP pyroelectric transfer standard detector. The pyroelectric transfer standard, which can operate at

Performance Evaluation of Robotic Knowledge Representation (PERK)

March 22, 2012
Author(s)
Craig I. Schlenoff, Sebti Foufou, Stephen B. Balakirsky
In this paper, we explore some ways in which symbolic knowledge representations have been evaluated in the past and provide some thoughts on what should be considered when applying and evaluating these types of knowledge representations for real-time

Determining the Location and Cause of Unintentional Quantum Dots in a Nanowire

March 21, 2012
Author(s)
Ted C. Thorbeck, Neil M. Zimmerman
Unintentional quantum dots are a common problem for single electron devices in both silicon and carbon. To determine the cause of these dots it is helpful to know their size and location. Because each dot is capacitively coupled to multiple gates, we can

Effective multibody interactions of harmonically confined ultracold neutral bosons

March 21, 2012
Author(s)
Philip Johnson, W F. Flynn, D Blume, X Y. Yin, Eite Tiesinga
We use renormalized perturbation theory to calculate effective two-, three-, and four-body interactions for N neutral ultracold bosons in the ground state of an isotropic harmonic trap, assuming only two-body interactions modeled with a zero-range

Frequency-stabilized cavity ring-down spectroscopy

March 21, 2012
Author(s)
David A. Long, A. Cygan, Roger D. van Zee, Mitchio Okumura, C. E. Miller, D Lisak, Joseph T. Hodges
This Frontiers article describes frequency-stabilized cavity ring-down spectroscopy (FS-CRDS), an ultraprecise refinement of conventional cw-CRDS. We review the technique and highlight some recent studies which have utilized FS-CRDS to perform precision

Measuring domain sizes and compositional heterogeneities in P3HT-PCBM bulk heterojunction thin films with 1H spin diffusion NMR spectroscopy

Author(s)
Ryan C. Nieuwendaal, Hyun Wook Ro, David Germack, Regis J. Kline, Calvin Chan, Amit K. Agrawal, David J. Gundlach, David L. VanderHart, Dean M. DeLongchamp
In this manuscript we show that 1H spin diffusion NMR is a valuable method for estimating the domain sizes in thin films of a polymer-fullerene blend for bulk heterojunction (BHJ) photovoltaics. Variations in common BHJ film processing parameters have

Modeling Line Edge Roughness in Lamellar Block Copolymer Systems

March 21, 2012
