Preliminary Studies on the Good, the Bad, and the Ugly Face Recognition Challenge Problem

November 26, 2012
Author(s)
P J. Phillips, J. R. Beveridge, David Bolme, Bruce A. Draper, Yui M. Lui
Face recognition has made significant advances over the last twenty years. State-of-the-art algorithms push the performanceenvelope to near perfect recognition rates on many face databases. Recently, the Good, the Bad, and the Ugly (GBU) face challenge

Division Polynomials for Jacobi Quartic Curves

June 13, 2011
Author(s)
Dustin Moody
In this paper we fi nd division polynomials for Jacobi quartics. These curves are an alternate model for elliptic curves to the more common Weierstrass equation. Division polynomials for Weierstrass curves are well known, and the division polynomials we fi

Quantum Key Distribution System Operating at Sifted-Key Rate Over 4 Mbit/s 1

June 1, 2009
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Hai Xu, Barry J. Hershman, Joshua C. Bienfang, David H. Su, Ronald F. Boisvert, Charles W. Clark, Carl J. Williams
A complete fiber-based polarization encoding quantum key distribution (QKD) system based on the BB84 protocol has been developed at National Institute of Standard and Technology (NIST). The system can be operated at a sifted key rate of more than 4 Mbit/s

Does Habituation Affect Fingerprint Quality?

February 20, 2007
Author(s)
Mary F. Theofanos, R J. Michaels, Jean C. Scholtz, Emile L. Morse, Peter May
Interest in the environmental factors that affect biometric image quality is increasing as biometric technologies are currently being implemented in various business applications. This study aims to determine, through repeated trials, the effects of

The Policy Machine for Security Policy Management

July 17, 2001
Author(s)
Chung Tong Hu, Deborah A. Frincke, David F. Ferraiolo
Many different access controls policies and models have been developed to suit a variety of goals: these include Role-Based Access Control, One-directional Information Flow, Chinese Wall, Clark-Wilson, N-person Control, and DAC, in addition to more

The Role of Choice in Discovery

January 1, 2000
Author(s)
J E. Devaney
The discovery of functional forms can be divided into three tasks:1 - choosing a search technique to find the set of best equationswithin the limitations of finite precision arithmetic and noise;2 - choosing from among the best equations based on some

Resilience-Runtime Tradeoff Relations for Quantum Algorithms

… errors. This paradigm is particularly prevalent in quantum computing, where gates are hard to implement and noise …

Formalizing ISA-95 Level 3 Control with Smart Manufacturing System Models

December 23, 2019
Author(s)
Leon F. McGinnis
Achieving the vision of "smart manufacturing and "Industrie 4.0" requires building on successes in computational control of processes to create generic approaches for management of manufacturing operations, or smart manufacturing operations management

Local-Field Correction for an Interstitial Impurity in Crystal

March 1, 2002
Author(s)
A Rahmani, P C. Chaumet, G C. Bryant
The local-field correction experienced by an interstitial impurity in a crystal with cubic symmetry is derived by use of a rigorous, self-sonsistent, semi-microscopic description of spontaneous emission in a microcavity. We compute the local-field factor

Quantitative Infrared Imaging of Impinging Turbulent Buoyant Diffusion Flames

July 2, 2014
Author(s)
Randall J. McDermott, Ashish Newale, Brent Rankin, Harshad Lalit, Jay P. Gore
Radiation from buoyant diffusion flames with and without impingement on a flat plate is studied using a unique quantitative comparison of measured and simulated images. The coupling between the stagnation boundary layer and upstream buoyant shear layer

Robustness of Steel Gravity Frame Systems with Single-Plate Shear Connections

February 27, 2013
Author(s)
Joseph A. Main, Fahim Sadek
This report presents a computational assessment of the performance of steel gravity framing systems with single-plate shear (“shear tab”) connections and composite floor slabs under column loss scenarios. The computational assessment uses a reduced

Report on Acceleration Comparison SIM.AUV.V-K1 - Draft B

March 20, 2009
Author(s)
David J. Evans, Adriana Hornikova, Stefan D. Leigh, Andrew L. Rukhin, William E. Strawderman
The first regional key comparison in vibration conducted under the auspices of the Inter-American System of Metrology (SIM) was begun in 1996. The comparison was registered with the International Bureau of Weights and Measures (BIPM) through the

A Straightforward Frequency-Estimation Technique for GPS Carrier-Phase Time Transfer

September 15, 2006
Author(s)
C Hackman, Judah Levine, Thomas E. Parker, Dirk Piester, Juergen Becker
GPS carrier-phase time transfer (GPSCPTT) offers high frequency stability at short averaging times, approaching a fractional frequency stability of 10 -15 at an averaging time of 1 d. However, a discontinuity occurs in the time-transfer estimates between
