Password policy languages: usable translation from the informal to the formal

July 21, 2015
Author(s)
Michelle P. Steves, Mary F. Theofanos, Celia Paulsen, Athos Ribeiro
Password policies – documents which regulate how users must create, manage, and change their passwords – can have complex and unforeseen consequences on organizational security. Since these policies regulate user behavior, users must be clear as to what is

Personalized Voting: The Intersection of Cloud and Mobility

July 21, 2015
Author(s)
Shanee T. Dawkins, Sharon J. Laskowski
Current research and development being conducted by the international Global Public Inclusive Infrastructure Consortium (GPII) is to create technology for cloud-based accessibility. Using this new technology, users of computer systems can create personal

PFLASH - Secure Asymmetric Signatures on Smart Cards

July 21, 2015
Author(s)
Ming-Shing Chen, Bo-Yin Yang, Daniel Smith-Tone
We present PFLASH, an asymmetric digital signature scheme appropriate for smart card use. We present parameters for several security levels in this low resource environment and bootstrap many technical properties (including side-channel resistance) exposed

Privacy and Security in the Brave New World: The Use of Multiple Mental Models

July 21, 2015
Author(s)
Susanne M. Furman, Mary F. Theofanos, Brian C. Stanton, Sandra S. Prettyman
We live in a world where the flow of electronic information and communication has become a ubiquitous part of our everyday life. While our lives are enhanced in many ways, we also experience a myriad of challenges especially to our priva-cy and security

Robotic Spherical Near-Field Measurements at 183 GHz

July 21, 2015
Author(s)
Michael H. Francis, Ronald C. Wittmann, David R. Novotny, Joshua A. Gordon
We describe millimeter-wave near-field measurements made with the new National Institute of Standards and Technology (NIST) robotic scanning system. This system is designed for high-frequency performance, is capable of scanning in multiple configurations

Perspective: What do we still need to understand to commercialize nanocellulose?

July 20, 2015
Author(s)
Chelsea S. Davis, Danielle L. Grolman, Alamgir Karim, Jeffrey W. Gilman
Cellulosic nanomaterials have the potential to become predominant nanoparticles utilized in materials engineering fields ranging from flexible electronic supports1–3 and tissue scaffolds4,5 to nanocomposite reinforcement materials6–9 and aerogels for oil

High Performance IAQ Specification for Net Zero Energy Homes

July 19, 2015
Author(s)
Anthony Bernheim, Alred Hodgson, Andrew K. Persily
The National Institute of Standards and Technology (NIST) constructed a Net Zero Energy Residential Test Facility (NZERTF) to support the development and adoption of cost-effective NZE designs and technologies. Key design objectives include providing

INDOOR ENVIRONMENTAL RESILIENCE: A REVIEW AND DISCUSSION

July 19, 2015
Author(s)
Andrew K. Persily, Steven J. Emmerich
NIST is developing a planning guide to define strategies to increase community-based resilience in the face of a broad range of natural disasters and other extreme events. Many of these events will affect indoor environmental quality (IEQ) either through

OVERVIEW OF NIST ACTIVITIES ON SUB-SIZE AND MINIATURIZED CHARPY SPECIMENS: CORRELATIONS WITH FULL-SIZE SPECIMENS AND VERIFICATION SPECIMENS FOR SMALL-SCALE PENDULUM MACHINES

July 19, 2015
Author(s)
Enrico Lucon, Christopher N. McCowan, Raymond L. Santoyo
NIST in Boulder Colorado investigated the correlations between impact test results obtained from standard, full-size Charpy specimens (CVN) and specimens with reduced thickness (sub-size Charpy specimens, SCVN) or reduced or scaled cross-section dimensions

Diff use interface methods for modeling drug eluting stent coatings

July 17, 2015
Author(s)
James A. Warren, David Saylor, Christopher Forrey, Changsoo Kim
An overview of diff use interface models specific to drug eluting stent coatings is presented. Microscale heterogeneities, both in the coating and use environment, dictate the performance of these coatings. Using diffuse interface methods, these

Uncertainty in the number of contributors in the proposed new CODIS set

July 17, 2015
Author(s)
Michael D. Coble, Jo-Anne Bright, John S. Buckleton, James Curran
The probability that multiple contributors are detected within a forensic DNA profile improves as more highly polymorphic loci are analysed. The assignment of the correct number of contributors to a profile is important when interpreting the DNA profiles

ADAPTING OECD AQUATIC TOXICITY TESTS FOR USE WITH MANUFACTURED NANOMATERIALS: KEY ISSUES, CONSENSUS RECOMMENDATIONS, AND DATA GAPS

July 16, 2015
Author(s)
Elijah J. Petersen, Alan Kennedy, Greg Goss, Ho Kay, Jamie Lead, Shannon Hanna, Kerstin Hund-Rinke, Brian Mader, Nicholas Manier, Pascal Pandard, Edward Salinas, Kathrin Schwirn, Doris Voelker
The unique or enhanced properties of manufactured nanomaterials (MNs) suggest that their use in nano-enabled products will continue to increase in the future. This will result in increasing potential for human and environmental exposure to MNs, during

Direct Observation of Carrier Cooling in Organic Semiconductors

July 16, 2015
Author(s)
Edwin J. Heilweil, Paul A. Lane, Paul D. Cunningham, Joseph S. Melinger
Photocurrent in an organic solar cell is generated by a charge transfer reaction between the electron donor and acceptor. The effect of excess excitation energy and the relative contributions of electron and hole transfer are the subject of intense

Indoor Environmental Resilience: White Paper

July 16, 2015
Author(s)
Andrew K. Persily, Steven J. Emmerich
NIST is developing a framework to define programs and strategies to increase community-based resilience in the face of a broad range of natural disasters and other extreme events. Many of these events will affect indoor environmental quality either through

Quantifying and Improving Clinical-grade Coverage and Accuracy using Augmented Exome Sequencing

July 16, 2015
Author(s)
Justin M. Zook, Anil Patwardhan, Marc L. Salit, Carlos Bustamante, Euan Ashley, Michael Snyder, John West, Richard Chen
Exome sequencing is increasingly used for the clinical evaluation of genetic disease, yet accuracy and coverage in medically interpretable parts of the genome remains under-characterized. We evaluate recently developed exome sequencing platforms in the

Challenges to the use of the GUM

July 15, 2015
Author(s)
Steven D. Phillips
Presentation at the BIPM on (1) Issues with the uncertainty evaluation associated with the calibration of indicating instruments; and (2) the growing problem with “outlier rejection” in measurements with measurands defined by “extreme values”

Defensive Resource Allocations with Security Chokepoints in IPv6 Networks

July 15, 2015
Author(s)
Assane Gueye, Peter M. Mell, Richard Harang, Richard J. La
