JPEG 2000 CODEC Certification Guidance for 1000 ppi Fingerprint Friction Ridge Imagery

April 13, 2016
Author(s)
John M. Libert, Shahram Orandi, Michael D. Garris, Frederick R. Byers, John D. Grantham
The document describes the procedure by which applications of JPEG 2000 CODECs will be evaluated with respect to conformance to the NIST guidance for compression of 1000 ppi friction ridge images as detailed in NIST Special Publication 500-289 [NIST5]

Generalized Probe-Position Compensation Methods for Near-Field Antenna Measurements

October 10, 2015
Author(s)
Michael H. Francis, Ronald C. Wittmann, Josh Gordon, David R. Novotny
The National Institute of Standards and Technology (NIST) has developed computationally efficient algorithms for probe location and polarization compensation in near- to far-field transformations for use when measurements are not made on the standard

Energy Transfer Between Eigenmodes in Multimodal Atomic Force Microscopy

November 5, 2014
Author(s)
Sang M. An, Santiago D. Solares Rivera, Sergio Santos, Daniel Ebeling
We present experimental and computational investigations of tetramodal and pentamodal atomic force microscopy (AFM), respectively, whereby the first four or five flexural modes of the cantilever are simultaneously excited externally. This leads to six to

Robustness Assessment of RC Frame Buildings under Column Loss Scenarios

April 3, 2014
Author(s)
Yihai Bao, Joseph A. Main, Hai S. Lew, Fahim Sadek
A computational assessment of the robustness of reinforced concrete (RC) building structures under column loss scenarios is presented. A reduced-order modeling approach is presented for three-dimensional RC framing systems, including the floor slab, and

Dissipative production of a maximally entangled steady state of two quantum bits

December 19, 2013
Author(s)
John P. Gaebler, Yiheng Lin, Florentin Reiter, Ting Rei Tan, Ryan S. Bowler, Anders Sorensen, Dietrich G. Leibfried, David J. Wineland
Entangled states are a key resource in fundamental quantum physics, quantum cryptography, and quantum computation [1]. To date, controlled unitary interactions applied to a quantum system, so-called "quantum gates'', have been the most widely used method

Exploratory Study of Airflow from SCBA Exposed to Elevated Temperatures

September 18, 2013
Author(s)
Michelle K. Donnelly, Daniel M. Madrzykowski, Anthony D. Putorti Jr.
This exploratory set of experiments investigated the impact of external exposure temperatures on Self Contained Breathing Apparatus (SCBA) supply air, and the potential for the supply air to be heated when it is subjected to an elevated temperature

Flux Lattices Reformulated

December 12, 2012
Author(s)
Ian B. Spielman, Gediminas Juzeliunas
We theoretically explore the optical flux lattices produced for ultra-cold atoms subject to laser fields where both the atom-light coupling and the effective detuning are spatially periodic. We analyze the geometric vector potential and the magnetic flux

SysML extension for dynamical system simulation tools

October 26, 2012
Author(s)
Ion Matei, Conrad E. Bock
Computer-interpretable representations of system structure and behavior are at the center of designing today’s complex systems. Engineers create and review such representations using graphical modeling languages that support specification, analysis, design

A Literature Review of the Effects of Fire Smoke on Electrical Equipment

July 31, 2012
Author(s)
Richard D. Peacock, Thomas G. Cleary, Paul A. Reneke, Daniel Murphy
A review is presented of the state of the art of smoke production measurement, prediction of smoke impact as part of computer-based fire modeling, and measurement and prediction of the impact of smoke through deposition of soot on and corrosion of

Mobile Application Device Power Usage Measurements

July 31, 2012
Author(s)
Rahul Murmuria, Jeffrey Medsger, Angelos Stavrou, Jeff Voas
… a crucial design tenet for both mobile and other small computing devices that are not constantly connected to a …

An Integrated Data Model for Quality Information Exchange in Manufacturing Systems

July 27, 2012
Author(s)
William G. Rippey, Yaoyao F. Zhao, Thomas R. Kramer, John A. Horst, Frederick M. Proctor
Quality measurement is an integrated part of modern manufacturing systems. As the manufacturing industry has entered a digital and virtual era, information technology has become increasingly important for both machining and measurement systems. Effective

MEMS

January 12, 2012
Author(s)
Michael Gaitan
Micro-Electro-Mechanical Systems (MEMS) are devices that are fabricated using techniques similar to those used for integrated circuits (ICs) to create micrometer-sized mechanical structures (suspended bridges, cantilevers, membranes, fluid channels, etc.)
