The Challenge of Face Recognition From Digital Point-and-Shoot Cameras

June 25, 2013
Author(s)
P J. Phillips, J. R. Beveridge, David Bolme, Bruce A. Draper, Geof H. Givens, Yui M. Lui, Hao Zhang, W T. Scruggs, Kevin W. Bowyer, Patrick J. Flynn, Su L. Cheng
Face recognition is appearing in personal and commercial products at an astonishing rate, yet reliable face recognition remains challenging. Users expect a lot; they want to snap pictures and have their friends, family and acquaintances recognized. This

Evaluation of dome-input geometry for pyroelectric detectors

June 24, 2013
Author(s)
Jinan Zeng, Leonard M. Hanssen, George P. Eppeldauer
Dome-input pyroelectric radiometers with different black coatings were developed to extend the spectral responsivity scale from near infrared (NIR) to 20 μm. The reflective dome with shiny gold-coating has been known to be an efficient light trap to

Harnessing 3D Scattered Optical Fields for sub-20 nm Defect Detection

June 24, 2013
Author(s)
Bryan M. Barnes, Martin Y. Sohn, Francois R. Goasmat, Hui Zhou, Richard M. Silver, Abraham Arceo
Experimental imaging at =193 nm of sub-resolved defects performed at several focus positions yields a volume of spatial and intensity data. Defects are located in a differential volume, given a reference, with up to 5x increase in sensitivity.

OBSERVATIONS ON THE GENERATION OF TOXIC PRODUCTS IN THE ISO/TS 19700 CONTROLLED EQUIVALENCE RATIO TUBE FURNACE AND THE CONTROLLED ATMOSPHERE CONE CALORIMETER

June 24, 2013
Author(s)
Nathan D. Marsh, Richard G. Gann, John R. Shields, Marc R. Nyden
Efforts are underway in several research groups to adapt existing flammability test methods for the determination of yields of toxic compounds such as CO, HCN, and HCl. These include the NFPA 269 / ASTM E 1678 radiant furnace apparatus, the ISO/TS 19700

Quantifying Network Topology Robustness Under Budget Constraints

June 24, 2013
Author(s)
Assane Gueye, Aron Lazska
To design robust network topologies that resist strategic attacks, one must first be able to quantify robustness. In a recent line of research, the theory of network blocking games has been used to derive robustness metrics for topologies. A network

A New Metric for Latent Fingerprint Image Preprocessing

June 23, 2013
Author(s)
Mary Frances Theofanos, Andrew Dienstfrey, Brian Stanton, Haiying Guan
Although fingerprint recognition is a well-studied area, forensic fingerprint preprocessing based on computational theory is still a relatively new domain in need of further scientific study and development of standards of best practice. Latent fingerprint

Four Measures of Nonlinearity

June 23, 2013
Author(s)
Joan Boyar, Magnus Find, Rene Peralta
Cryptographic applications, such as hashing, block ciphers and stream ciphers, make use of functions which are simple by some criteria (such as circuit implementations), yet hard to invert almost everywhere. A necessary condition for the latter property is

Dexterous Manipulation for Manufacturing Applications Workshop

June 21, 2013
Author(s)
Joseph A. Falco, Jeremy A. Marvel, Elena R. Messina
The National Institute of Standards and Technology organized a free workshop in conjunction with the 2013 Automate and ProMat trade shows in Chicago, IL. The workshop addressed the application of dexterous robot technologies to meet the application needs

Enabling an Enterprise-wide, Data-centric Operating Environment

June 21, 2013
Author(s)
David F. Ferraiolo, Serban I. Gavrila, Wayne Jansen
Although access control (AC) currently plays an important role in securing DSs, if properly envisaged and designed, access control can serve a more vital role in computing than one might expect. The Policy Machine (PM), a framework for AC developed at NIST

Exposing Software Security and Availability Risks For Commercial Mobile Devices

June 21, 2013
Author(s)
Ryan Johnson, Zhaohui Wang, Angelos Stavrou, Jeff Voas
In this manuscript, we present our efforts towards a framework for exposing the functionality of a mobile application through a combination of static and dynamic program analysis that attempts to explore all available execution paths including libraries

Guidelines for Managing the Security of Mobile Devices in the Enterprise

June 21, 2013
Author(s)
Murugiah P. Souppaya, Karen Scarfone
Mobile devices, such as smart phones and tablets, typically need to support multiple security objectives: confidentiality, integrity, and availability. To achieve these objectives, mobile devices should be secured against a variety of threats. The purpose

Lessons Learned in Establishing the NIST Metal Additive Manufacturing Laboratory

June 21, 2013
Author(s)
Shawn P. Moylan, John A. Slotwinski, April Cooke, Kevin K. Jurrens, M A. Donmez
This publication presents a summary of lessons learned by NIST staff during establishment of the NIST Metal Additive Manufacturing Laboratory and implementation of the metal additive manufacturing capability at NIST. These lessons learned resulted from the

Detection of Topological Matter with Quantum Gases

June 20, 2013
Author(s)
Ian B. Spielman
Creating and measuring topological matter – with order deeply imbedded it’s quantum mechanical eigenstates structure – presents unique experimental challenges. This sort of intrinsically non-local order might seem experimentally inaccessible in any
