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.

Architecture of Focus 3D Telemodeling Tool

August 1, 2006
Author(s)
Arthur Griesser
A high level design of Focus 3D Telemodeling tool is presented. Infrastructure components are selected in the light of the functional and non functional requirements of the Focus project. A description of how these components will fit together is provided

Automated Generation of AnIML Documents by Analytical Instruments

August 1, 2006
Author(s)
Alexander Roth, Ronny Jopp, R Schaefer, Gary W. Kramer
The scope of this project covers the storing of result data produced by generic laboratory devices during processing of analytical experiments, together with the data describing the examination methods and the audit trail using the AnIML (Analytical

Calcium Phosphate Cement With Non-Rigidity and Strength Durability for Periodontal Bone Repair

August 1, 2006
Author(s)
Hockin D. Xu, Shozo Takagi, Limin Sun, L A. Hussain, Laurence C. Chow, William F. Guthrie, James H. Yen
Background. The need for biomaterials to treat periodontal osseous defects has increased as the world population ages. The objective of the present study was to develop a self-hardening, resorbable, and mech/anically strong calcium phosphate cement (CPC)

Calibration of Sampling Oscilloscopes With High-Speed Photodiodes

August 1, 2006
Author(s)
Tracy S. Clement, Paul D. Hale, Dylan Williams, C. M. Wang, Andrew Dienstfrey, Darryl A. Keenan
We calibrate the magnitude and phase response of equivalent-time sampling oscilloscopes to 110 GHz. We use a photodiode that has been calibrated with our electrooptic sampling system as a reference input pulse source to the sampling oscilloscope. We
