Proposed Development of a National Standard for Microwave Brightness Temperature

August 4, 2006
Author(s)
James P. Randa, Amanda Cox, Dave K. Walker
We review the advantages of a national standard for microwave brightness temperature and outline our proposed approach toward developing such a standard. The proposal is a combined standard that would comprise both a standard radiometer, traceable to

The Glass Transition of Miscible Binary Polymer-Polymer Thin Films

August 4, 2006
Author(s)
Brian M. Bescancon, Christopher Soles, P A. Green
The average glass transition temperatures, Tg, of thin homopolymer films exhibit a thickness dependence, Tg(h), determined by a confinement effect and by the polymer segment/interface interactions. The Tgs of completely miscible thin film blends of

Transport dynamics of single ions in segmented microstructured Paul trap arrays

August 4, 2006
Author(s)
Rainer Reichle, Dietrich G. Leibfried, Brad R. Blakestad, Joseph W. Britton, John D. Jost, Emanuel H. Knill, C. Langer, R Ozeri, Signe Seidelin, David J. Wineland
It was recently proposed to use small groups of trapped ions as qubit carriers in miniaturized electrode arrays that comprise a large number of individual trapping zones, between which ions could be moved. This approach might be scalable for quantum

Load-Displacement Relations for Nanoindentation of Viscoelastic Materials

August 2, 2006
Author(s)
Chien-Kuo Liu, S H. Lee, Li Piin Sung, Tinh Nguyen
A model based on the Burgers viscoelastic concept has been developed to describe the nanoindentation behaviors of polymeric materials. An analytical solution of displacement at the indenter tip has been derived based on the analog of the governing equation

Scanning Temperature Gradient Focusing

August 2, 2006
Author(s)
S J. Hoebel, K M. Balss, Barbara J. Jones, C Malliaris, Matt S. Munson, Wyatt N. Vreeland, David J. Ross
Temperature gradient focusing (TGF) is a recently developed technique for the simultaneous concentration and electrophoretic separation of ionic analytes in microfluidic channels. One drawback to TGF as it has previously been described is the limited peak

A compact phase delay technique for increasing the amplitude of coherent population trapping resonances in open Lambda systems

August 1, 2006
Author(s)
V Shah, Svenja A. Knappe, P Schwindt, Vladislav Gerginov, John E. Kitching, Leo W. Hollberg
We propose and demonstrate a novel technique for increasing the amplitude of coherent population trapping (CPT) resonance in open Lambda systems. The technique requires no complex modifications to the conventional CPT setup and is compatible with standard

A Hybrid Finite Element-Analytical Method For Determining the Intrinsic Elastic Moduli of Particles Having Moderately Extended Shapes and a Wide Rande of Elastic Properties

August 1, 2006
Author(s)
Edward J. Garboczi, Jack F. Douglas, Howard Hung
The presence of a low (dilute) concentration of paniculate inclusions having any shape and any property mismatch with the matrix in which they are placed, influences the elasticity of the resulting composite material. This influence is via the intrinsic

A Validation Architecture for Advanced Interoperability Provisioning

August 1, 2006
Author(s)
Nenad Ivezic, Edward J. Barkmeyer Jr., Boonserm Kulvatunyou, Albert W. Jones, Pat Snack, Zuran Marjanovic, Hyunbo Cho
We describe an architecture to validate new tools in support of interoperability provisioning processes that take place within industrial communities. We start from a best-practices standards development process where an industry community develops

Addressing Security in the Early Stages of the Project Life Cycle

August 1, 2006
Author(s)
Benjamin Matthews, Jonathan Sylvie, Edd Gibson, Stephen R. Thomas, Robert E. Chapman, Sang-Hoon Lee
This article summarizes the first phase of a three-phase research effort to develop and deploy best practices for project security on industrial projects. It shows how to address security early in the project life cycle and its impacts on the capital

An Infrastructure to Support Performance Analysis in Complex Systems

August 1, 2006
Author(s)
Man-Sze Li, A S. Deshmukh, Albert T. Jones
Systems research efforts have increased in a variety of disciplines. Despite these efforts, it is still difficult to predict long-term performance and to understand the relationship between the performance of the parts and the performance of the whole. The

An Overview of the Josephson Voltage Standard Interlaboratory Comparison

August 1, 2006
Author(s)
Yi-hua Tang
A majority of Josephson Voltage Standard (JVS) interlaboratory comparisons have been performed by using Zener voltage transfer standards and a protocol based on the Measurement Assurance Program (MAP) with uncertainties in the range of a few parts in 108

Analysis Catalog for Focus 3D Telemodeling Tool

August 1, 2006
Author(s)
Arthur Griesser
A high level view of the requirements for the Focus 3D Telemodeling tool is presented. The scope of the project is defined, users of the system are described, an analysis class diagram is presented, and use cases are outlined.
