Combinatorial Coverage Analysis of Subsets of the TLS Cipher Suite Registry

May 11, 2016
Author(s)
Dimitris Simos, Kristoffer Kleine, D. Richard Kuhn, Raghu N. Kacker
We present a combinatorial coverage measurement for (subsets) of the TLS cipher suite registries by analyzing the specified ciphers of IANA, ENISA, BSI, Mozilla and NSA Suite B. Our findings contribute towards the design of quality measures of recommended

Uncertainty of Error: The Error Dilemma

May 11, 2016
Author(s)
Charles D. Ehrlich
Measurement error has historically been defined in the metrology community as a difference of 'values,' usually as a difference between a 'measured value' and a 'reference value.' The reference value is sometimes considered to be a 'true value,' which is

Enhancing Single-Wall Carbon Nanotube Properties Through Controlled Endohedral Filling

May 10, 2016
Author(s)
Jochen I. Campo, Yanmei Piao, Stephanie Lam, Christopher Stafford, Jason K. Streit, Jeffrey R. Simpson, Angela R. Hight Walker, Jeffrey Fagan
Chemical control of the endohedral volume of single-wall carbon nanotubes (SWCNTs) via liquid-phase filling is demonstrated to be a facile strategy to controllably modify properties of the nanotubes in manners significant for processing and proposed

National Voluntary Laboratory Accreditation Program (NVLAP) Calibration Laboratories

May 10, 2016
Author(s)
Barbara J. Belzer, Kari K. Harper, Thomas R. Hettenhouser, Warren R. Merkel
NIST Handbook 150-2, 2016 edition, presents the technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Calibration Laboratories Program. The 2016 edition of NIST

Real-Time, Single Molecule Electronic DNA Sequencing by Synthesis Using Polymer Tagged Nucleotides on a Nanopore Array

May 10, 2016
Author(s)
Carl Fuller, Shiv Kumar, Mintu Porel, Michen Chien, Arek Bibillo, P. B. Stranges, Michael Dorwart, Chuanjua Tao, Zengmin Li, Wenjing Guo, Shundi Shi, Daniel Korenblum, Andrew Trans, Anne Aguirre, Edward Liu, Takeshi Harada, James Pollard, Ashwini Bhat, Cynthia Cech, Alexander Yang, Cleoma Spilman, Mirko Palla, Jennifer Hovis, Roger Chen, Irina Morozova, Sergey Kalachikov, James Russo, John J. Kasianowicz, Stefan Roever, George Church, Jingyue Ju
DNA sequencing by synthesis (SBS) offers a robust platform to decipher nucleic acid sequences. Recently, we developed a single molecule nanopore-based SBS strategy (NanoSBS) that accurately distinguishes four bases by electronically detecting and

Stress Analysis of Conical Contact Joints in the NIST 4.45 MN Deadweight Machine

May 10, 2016
Author(s)
Nicholas A. Vlajic, Akobuije D. Chijioke, Ricky L. Seifarth
Structural analysis of conical contact joints in the NIST 4.45 MN Dead Weight Machine using finite element analysis is presented in this paper. This analysis was undertaken due to the observation of surface damage in these joints. Parametric studies are

Synthesis, Fabrication, and Heterostructure of Charged, Substituted Polystyrene Multilayer Dielectrics and Their Effects in Pentacene Transistors

May 10, 2016
Author(s)
Olivia J. Alley, Evan Plunkett, Tejaswini S. Kale, Xin Guo, Grace McClintock, Manasa Bhupathiraju, Brian Kirby, Daniel H. Reich, Howard E. Katz
Charge trapping and storage in polymer dielectric can be harnessed for the control of semiconductor device behavior, including organic transistors. For example, gate insulators chosen for organic transistors have an important effect on both bias stress

Automating Robot Planning using Product and Manufacturing Information

May 9, 2016
Author(s)
Frederick M. Proctor, Gijs van der Hoorn, Robert R. Lipman
Advances in sensing, modeling, and control have made it possible to increase the accuracy of robots, and enable them to perform in dynamic environments. Often, performance deficiencies are not evident until late in the development of the manufacturing

Comparison of T1 measurement using ISMRM/NIST system phantom

May 9, 2016
Author(s)
Kathryn E. Keenan, Karl F. Stupic, Michael A. Boss, Stephen E. Russek, Thomas L. Chenevert, Pottumarthi V. Prasad, Wilburn E. Reddick, Jie Zheng, Peng Hu, Edward F. Jackson
We used the ISMRM/NIST system phantom to assess variations of T1 measurements across MRI systems at 1.5 T and 3 T, to determine the repeatability and reproducibility of the T1 measurements. This study demonstrates that T1 variations from NMR-measured value

DELAY MEASUREMENT OF 1PPS SIGNALS IN TIMING SYSTEMS

May 9, 2016
Author(s)
Stefania Romisch, Daniele Rovera, Marco Siccardi
Abstract The uncertainty of time measurements in timing systems is not only a function of the quality of the instruments and system components (time interval counters, pulse distribution amplifiers, GNSS receivers) but lays also in the quality of the

Dynamic Onset of Feynman Relation in the Phonon Regime

May 9, 2016
Author(s)
Lu Deng, Edward W. Hagley, Yan Li, Chengjie Zhu
The Feynman relation 1, a much celebrated condensed matter physics gemstone for more than 70 years, predicts that the density excitation spectrum and structure factor of a condensed Bosonic system in the phonon regime drops linear and continuously to zero

End-to-End Quality Information Framework (QIF) Technology Survey

May 9, 2016
Author(s)
John L. Michaloski, Thomas D. Hedberg, Hui-Min Huang, Thomas R. Kramer
The goal of this paper is to understand how quality information characterizing the manufactured parts can be reported in a XML standardized format. The Quality Information Framework (QIF) is an ANSI standard sponsored by the Dimensional Metrology Standards

High Thermopower with Metallic Conductivity in p-Type Li-Substituted PbPdO 2

May 9, 2016
Author(s)
Leo K. Lamontagne, Geneva Laurita, Michael W. Gaultois, Michael Knight, Leila Ghadbeigi, Taylor D. Sparks, Markus E. Gruner, Rossitza Pentcheva, Craig Brown, Ram Seshadri
PbPdO 2 is a band semiconductor with a band gap arising from the filled d 8 nature of square-planar Pd 2+. We establish that hole doping through Li substitution for Pd in PbPdO 2 results in a p-type metallic oxide with a positive temperature coefficient of

Early age hydration kinetics of Portland cement with pozzolanic volcanic ash was examined using quasi-elastic neutron scattering. Volcanic ash consisting of two different particle sizes was used to prepare cement pastes by combinations of Portland cement

Measurement of AM-to-PM Conversion in a Quartz-MEMS Resonator

May 9, 2016
Author(s)
Craig W. Nelson, Archita Hati, David A. Howe
This work investigates the new aspects of the non-linear response in a quartz-MEMS resonator at 635 MHz. We characterize its major cause of AM-to-PM conversion as a function of power and drive frequency; this is important in developing noise compensation
