Derived PIV Application and Data Model Test Guidelines

June 6, 2016
Author(s)
David Cooper, Hildegard Ferraiolo, Ramaswamy Chandramouli, Nabil Ghadiali, Jason Mohler, Steven Brady
NIST Special Publication (SP) 800-157 contains technical guidelines for the implementation of standards-based, secure, reliable, interoperable Public Key Infrastructure (PKI)-based identity credentials that are issued for mobile devices by federal

FEA parameter verification for strain localization experiments

June 6, 2016
Author(s)
Mark A. Iadicola, Dilip K. Banerjee, Adam A. Creuziger
Multi-axial specimen geometry optimization through finite element analysis requires robust models that incorporate the critical physics of the experiment as well as a sufficiently robust constitutive law. This can be difficult even at low nominal strain

Opportunities for Inverse Analysis in Dynamic Tensile Testing

June 6, 2016
Author(s)
Steven P. Mates, Fadi Abu-Farha
Dynamic tensile testing using Kolsky Bar methods are used to assess crashworthiness of new structural materials needed for lightweight automotive design. High speed Digital Image Correlation (DIC) measurements routinely show that the strain experienced by

Phase-coherent microwave-to-optical link with a self-referenced microcomb

June 6, 2016
Author(s)
Pascal P. Del'Haye, Aurelien C. Coillet, Tara M. Fortier, Katja M. Beha, Daniel C. Cole, Hansuek Lee, Kerry J. Vahala, Scott B. Papp, Scott A. Diddams
The counting and control of optical cycles of light has become common with modelocked laser frequency combs. But even with advances in laser technology, modelocked laser combs remain bulk-component devices that are hand-assembled. In contrast, a frequency

Propagation of Error from Registration Parameters to Transformed Data

June 6, 2016
Author(s)
Mili Shah, Marek Franaszek, Geraldine Cheok
Methods to register two sets of data have existed for quite some time. However, these sets of data are rarely error-free. Consequently, any parameters obtained from a registration method will be affected by the error in the sets of data. Moreover, if these

Thermometry with Optomechanical Cavities

June 6, 2016
Author(s)
Thomas P. Purdy, Karen E. Grutter, Kartik Srinivasan, Nikolai Klimov, Zeeshan Ahmed, Jacob Taylor
Thermally-driven motion of a nanomechanical resonator may be employed as an absolute thermometer. We experimentally measure radiation pressure shot noise induced quantum correlations to absolutely calibrate the motional signal transduced onto an optical

Measurement of DNA repair protein apurinic/apyrimidinic endonuclease 1 (APE1) in human tissues by liquid chromatography/tandem mass spectrometry with isotope dilution

June 5, 2016
Author(s)
Pawel Jaruga, Guldal Kirkali, Prasad T. Reddy, Alessandro Tona, Bryant C. Nelson, Li Mengxia, David M. Wilson III, Erdem Coskun, M Miral Dizdar
Introduction DNA repair proteins may be used as biomarkers in disease etiology and therapy. Thus, the accurate determination of DNA repair protein expression and genotype in human tissues is of fundamental importance. Apurinic/apyrimidinic endonuclease 1

A Programmable Solar Simulator for Realistic Seasonal, Diurnal, and Air-Mass Testing of Multi-Junction Concentrator Photovoltaics

June 4, 2016
Author(s)
Tasshi Dennis, chanud yasanayake, Tim Gerke, Alex Payne, Lars Eng, brent fisher, Matt Meitl
We built a spectrally programmable super-continuum solar simulator and applied it to the realistic laboratory testing of a multi-junction concentrator solar cell. The novel simulator generated a broad range of illumination conditions representing changes
