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

Interface Characterization of Molecular-Monolayer/SiO2 Based Molecular Junctions

August 1, 2006
Author(s)
Curt A. Richter, Christina Hacker, Lee J. Richter, Oleg A. Kirillov, Eric M. Vogel
The properties of monolayers of molecules on thin SiO2 are of great interest for future hybrid Si-molecular device technologies. We present here a correlation of the results of dc-current-voltage (IV) and capacitance-voltage (CV) measurements with

Measurement of 100 nm and 60 nm Particle Standards by Differential Mobility Analysis

August 1, 2006
Author(s)
George W. Mulholland, Michelle K. Donnelly, Robert C. Hagwood, S R. Kukuck, Vincent A. Hackley, D Y. Pui
The peak particle size and expanded uncertainties (95 % confidence interval) for two new particle calibration standards are measured as 101.60 nm ? 1.02 nm and 60.68 nm ? 0.59 nm. The particle samples are polystyrene spheres suspended in filtered

Media Longevity Sidebar for INSIC

August 1, 2006
Author(s)
Oliver T. Slattery
The long-term preservation of digital data is a fundamental objective for many government agencies, businesses and individuals alike. With positive claims from manufacturers with regard to longevity, optical media has generated interest among the archival

MEMS Sensors for HVAC&R: Small, Fast, Cheap (in Polish)

August 1, 2006
Author(s)
David A. Yashar, Piotr A. Domanski
Microelectronic mechanical systems (MEMS) have revolutionized the market for sensors by providing small, fast-responding measurement devices at low cost. They have been widely accepted in several common products. As an example, today's automobile uses

Minimum-phase calibration of sampling oscilloscopes

August 1, 2006
Author(s)
Andrew Dienstfrey, Paul D. Hale, Darryl A. Keenan, Tracy S. Clement, Dylan Williams
We describe an algorithm for determining the minimum phase of a linear, time-invariant response function from its magnitude. The procedure is based on Kramers-Kronig relations in combination with auxiliary direct measurements of the desired phase response

Multiple Description Video Coding over Multiple Path Routing Networks

August 1, 2006
Author(s)
Shaoshuai Gao, Hamid Gharavi
This paper presents a multiple description (MD) video-coding scheme, which uses interlaced high signal to noise ratio (H-SNR) and low signal to noise ratio (L-SNR) coded frames to produce two bit-streams. At the decoder, when both bit-streams are received

August 1, 2006
Author(s)
Iosif I. Shinder, Iryna V. Marfenko
This document describes the Water Flow Calibration Facility (WFCF) at the National Institute of Standards and Technology (NIST). This facility has three parallel pipelines with diameters of 100, 200 and 400 mm and three weighing systems with capacities of

On-Chip Electrostatic Discharge Protection for CMOS Gas Sensor Systems-on-a-Chip (SoC)

August 1, 2006
Author(s)
Javier Salcedo, Juin J. Liou, Muhammad Y. Afridi, Allen R. Hefner Jr.
An on-chip Electrostatic Discharge (ESD) protection scheme is demonstrated for MicroElectroMechanical Systems (MEMS)-based Embedded Sensor (ES) System-on-a-Chip (SoC). The ESD protection scheme is implemented with ground-referenced multifinger thyristor

Papers From 1991-2006 Halon Options Technical Working Conferences (HOTWC)

August 1, 2006
Author(s)
Richard G. Gann, Star R. Burgess, Kathleen C. Whisner, Paul A. Reneke
As a result of the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer and the 1990 U.S. Clean Air Act, there began a movement toward phaseout of the use of the halon fire suppressants. The HOTWC was initiated as a forum for such contributory

Performance Standards for Urban Search and Rescue Robots

August 1, 2006
Author(s)
Elena R. Messina
This article describes the motivation and approach for developing standard test methods for robots applied to urban search and rescue missions. The work is being carried out by Task Group E54.08.01, which is within the Operational Equipment subcommittee
