Predicting Material In-Service Performance using the NIST SPHERE

June 17, 2009
Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan
Selecting a polymeric material for an application exposed to outdoor weathering is a challenging task. The proper selection requires knowledge of the behavior of the material, which is a complex mixture involving the integration of rheology, reliability

Laboratory Effects Models for Interlaboratory Comparisons

June 16, 2009
Author(s)
Blaza Toman, Antonio M. Possolo
Statistical analysis of inter-laboratory comparisons (e.g. Key Comparisons, Supplemental Comparisons) is required to produce an estimate of the measurand called a reference value and further, measures of equivalence of the participating laboratories

Vacuum-Gap Capacitors for Low-Loss Superconducting Resonant Circuits

June 16, 2009
Author(s)
Katarina Cicak, Michael S. Allman, Joshua Strong, Kevin Osborn, Raymond W. Simmonds
Low-loss microwave components are used in many superconducting resonant circuits from multiplexed readouts of low-temperature detector arrays to quantum bits. Two-level system (TLS) defects in amorphous dielectric materials cause excess energy loss. In an

A Measure of Product Sustainability Based on Triple Bottom Line

June 15, 2009
Author(s)
Prabir Sarkar, Sudarsan Rachuri, Hyo Won Suh, Kevin W. Lyons, Ram D. Sriram
Sustainable societies require the use of sustainable products. Sustainability is generally expressed in terms of Triple Bottom Line (TBL) - people, planet, and profit. Products that are sustainable have positive effects and value for all the stakeholders

Cyber Security Standards

June 15, 2009
Author(s)
Karen A. Scarfone, Daniel R. Benigni, Timothy Grance
The goal of cyber security standards is to improve the security of information technology (IT) systems, networks, and critical infrastructures. A cyber security standard defines both functional and assurance requirements within a product, system, process

Fracture toughness measurement of thin nanoporous films on stiff substrates

June 15, 2009
Author(s)
Dylan Morris, Robert F. Cook
Nanoporous low-dielectric-constant films constitute a class of materials that are plagued by fracture concerns and are not amenable to traditional fracture toughness measurement techniques. An indentation fracture toughness measurement technique has been

Hashing Techniques for Mobile Device Forensics

June 15, 2009
Author(s)
Richard Ayers, Shira Danker, Rick Mislan
Technological advances found in mobile devices today, equal or exceed that of the computing power present in desktop computers of less than a decade ago. As mobile devices proliferate, techno-logical advances provide users with increased power, range

Minutia Interoperability

June 15, 2009
Author(s)
Elham Tabassi
Many large scale identity management applications require storage and exchange of standardized minutiae templates. Minutia templates offer a more space efficient, less resource intensive, and more cost effective alternative to raw images. Recent minutiae

Niobium-silicide Junction technology for superconducting digital electronics

June 15, 2009
Author(s)
David I. Olaya, Paul D. Dresselhaus, Samuel P. Benz
Digital superconducting electronics (SCE), which allows for very low power consumption and fast switching speeds, are a promising technology to deliver ultra-high performance computation. Currently, the preferred technology for junctions in SCE consists of

OntoSTEP: OWL-DL Ontology for STEP

June 15, 2009
Author(s)
Sylvere Krima, Raphael Barbau, Xenia Fiorentini, Sudarsan Rachuri, sebti foufou, Ram D. Sriram
The Standard for the Exchange of Product model data (STEP) [1] contains product information mainly related to geometry. The modeling language used to develop this standard, EXPRESS, does not have logical formalism that will enable rigorous semantics. In

Semantic-Mediation for Standards-based B2B Interoperability

June 15, 2009
Author(s)
Marko Vujasinovic, Nenad Ivezic, Boonserm Kulvatunyou, Edward J. Barkmeyer Jr., Michele Missikoff, Francesco Taglino, Zoran Marjanovic, Igor Miletic
The authors discuss a semantic-mediation architecture to advance traditional approaches for standards-based business-to-business (B2B) interoperability. The architecture is supported by the ATHENA Knowledge Representation and Semantics Mediation tool suite

The contribution of lipid layer movement to tear film thinning and breakup

June 15, 2009
Author(s)
Geoffrey B. McFadden, Christopher Smith, Barbara A. Fink, Jason J. Nichols, Richard J. Braun
The purpose of this study is to investigate the origin of the tear film thinning between blinks, which can lead to tear film breakup and ocular surface damage. Two mechanisms of thinning are considered: "tangential flow" of the tear film along the surface

A microfabricated photonic magnetometer

June 14, 2009
Author(s)
Jan Preusser, Svenja A. Knappe, Vladislav Gerginov, John E. Kitching
A system for sensing magnetic fields is proposed, composed of an array of passive microfabricated alkali atom sensor heads coupled to a control unit using only optical interconnects. The optical coupling can be achieved by either free-space transmission of

Measuring Indoor Mobile Wireless Link Quality

June 14, 2009
Author(s)
Michael R. Souryal
This paper investigates methods for link quality measurement of an indoor, time-varying wireless link. Link quality estimates are used for a number of higher-layer functions, including rate adaptation, routing, and topology control. The objective is to

Thermoelectric and Structural Characterization of Ba2Ho(Cu3-xCox)O6+y

June 13, 2009
Author(s)
Winnie K. Wong-Ng, Z Yang, Y F. Hu, Qingzhen Huang, Nathan Lowhorn, Makoto Otani, James A. Kaduk, Martin L. Green, Q Li
The search for thermoelectric materials for power generation and for solid-state cooling have led to the increased interest of layered cobalt-containing oxides because of their thermal stability at high temperature and their desirable thermoelectric
