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

Concrete Multiplicative Complexity of Symmetric Functions

August 1, 2006
Author(s)
Joan Boyar, Rene Peralta
The multiplicative complexity of a Boolean function f is defined as the minimum number of binary conjunction (AND) gates required to construct a circuit representing f, when only exclusive-or, conjunction and negation gates may be used. This article

Dark Encounter Computations (And Musings on Biological Networks)

August 1, 2006
Author(s)
Rene C. Peralta
We describe two models of distributed computation in which the agents are anonymous finite-state sensors interacting through a communication network whose dynamics (in case the agents are mobile) and/or topology they do not control or even know about

Demonstration of an Active Quantum Key Distribution Network

August 1, 2006
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Hai Xu, Barry J. Hershman, Joshua Bienfang, David H. Su, Ronald Boisvert, Charles W. Clark, Carl J. Williams
We previously demonstrated a high speed, point to point, quantum key distribution (QKD) system with polariztion coding over a fiber link, in which the resulting cryptographic keys were used for one-time pad encryption of real time video signals. In this

Development of a Radioanalytical Emergency Procedures Manual Database (REPMD)

August 1, 2006
Author(s)
J J. La Rosa, P Motabar, Kenneth G. Inn, H Ziegler
A Radioanalytica Emergency Procedures Manual Database (REPMD) will be an important tool assist laboratories preparing for emergency response to a sudden release of radioactitivy into the environment. The collection and systematic organization of existing

Editorial for IEEE Transactions on Microwave Theory and Techniques Mini-Special Issue on Large-Signal Characterization and Modeling of Nonlinear Analog Devices, Circuits, and Systems

August 1, 2006
Author(s)
Kate Remley, Nuno de Carvalho, David Root
As Guest Editors, we are honored and excited to introduce this Mini-Special Issue of the Transactions devoted to Measurements for Large-Signal Characterization and Modeling of Nonlinear Analog Devices, Circuits, and Systems. Large-signal measurements

Evaluating Suitability for Replacement of an Integrated Software Component

August 1, 2006
Author(s)
Boonserm Kulvatunyou, B Jeong, Hyunbo Cho, Nenad Ivezic, Albert W. Jones
An evaluation of the compatibility of a software component is based typically only on a vendor?s presentation. This means that end users select a software component only based on high-level matches of functional requirements. This can result in an

Feature Technology and Ontology for Embedded System Design and Development

August 1, 2006
Author(s)
XuanFang Zha, Ram D. Sriram
In this paper, we present our recent effort on using a feature technology and ontology for embedded systems modeling and design. We present an overview of embedded system design and propose an object-oriented UML modeling approach to representing embedded

Injectable and Macroporous Calcium Phosphate Cement Scaffold

August 1, 2006
Author(s)
Hockin D. Xu, Michael Weir, Elena F. Burguera, A M. Fraser
Calcium phosphate cement (CPC) can be molded and self-harden in vivo to form resorbable hydroxyapatite with excellent osteoconductivity. The objective of this study was to develop an injectable, macroporous and strong CPC scaffold, and to investigate the
