Performance Analysis of 10 kV, 100 A SiC Half-Bridge Power Modules

March 3, 2008
Author(s)
Allen R. Hefner Jr.
Abstract: The DARPA Wide Bandgap Semiconductor Technology (WBGS) High Power Electronics (HPE) Phase II program is developing high-voltage, high-frequency SiC device and package technology needed to meet the specific program objectives for a 13.8 kV, 2.75

Two-Body Transients in Coupled Atomic-Molecular BECs

March 3, 2008
Author(s)
Pascal Naidon, Eite Tiesinga, Paul S. Julienne
We discuss the dynamics of an atomic Bose-Einstein condensate when pairs of atoms are converted into molecules by single-color photoassociation. Three main regimes are found and it is shown that they can be understood on the basis oftime-dependent two-body

Development of Infrared Scene Projectors for Fire Fighter Cameras

March 2, 2008
Author(s)
Joseph P. Rice, Jorge E. Neira, Francine K. Amon
We have developed two types of infrared scene projectors for hardware-in-the-loop testing of thermal imaging cameras such as those used by fire-fighters. In one, direct projection, images are projected directly into the camera. In the other, indirect

Commutability of NIST SRM 1955 Homocysteine and Folate in Frozen Human Serum With Selected Total Homocysteine Immunometric or Enzymatic Assays

March 1, 2008
Author(s)
B C. Nelson, Christine M. Pfeiffer, Ming Zhang, David L. Duewer, Katherine E. Sharpless, Katrice Lippa
Background: The National Institute of Standards and Technology (NIST) and the Centers for Disease Control and Prevention (CDC) have recently developed Standard Reference Material (SRM) 1955 Homocysteine and Folate in Frozen Human Serum with certified

Engineering Informatics: Introduction to the Special Issue

March 1, 2008
Author(s)
Sudarsan Rachuri, Eswaran Subrahmanian
Computer-aided design, intelligent CAD, engineering analysis, collaborative design support, computer-aided engineering, and product lifecycle management are some of the terms that have emerged over the last 50 years of computing in engineering

Minimizing Information Leakage in the DNS

March 1, 2008
Author(s)
Scott W. Rose, Anastase Nakassis
The Domain Name System (DNS) is the global lookup service for network resources. To protect DNS information, the DNS Security Extensions (DNSSEC) has been developed and deployed on branches of the DNS to provide authentication and integrity protection

Sub-Wavelength Resonators: On the use of Metafilms to Overcome the l/2 size limit

March 1, 2008
Author(s)
Christopher L. Holloway, Derik Love, Edward E. Kuester, Alesandro Salandrino, Nader Engheta
Metamaterials, in particular, double negative materials, have been used in the design of electromagnetic resonators as a means to overcome the classical $\lambda/2$ requirement. The surface equivalent of a metamaterial is a so-called metafilm, and is

The Beginnings of This TRANSACTIONS

March 1, 2008
Author(s)
Dylan F. Williams, Admir Mortazawi
In July, 1951, Ben Warriner (chairman, 1952-1953) circulated a petition to begin the Microwave Theory and Techniques Society under the auspices of the Institute of Radio Engineers. Despite an initial lack of support from the IRE, the roots of the

MINEX II Performance of Fingerprint Match-on-Card Algorithms - Phase II Report

February 29, 2008
Author(s)
Patrick J. Grother, Wayne J. Salamon, Michael D. Indovina, Craig I. Watson
The MINEX II trial was conducted to evaluate the accuracy and speed of Match-on-Card verification algorithms. These run on ISO/IEC 7816 smart cards. They compare conformant reference and verification instances of the ISO/IEC 19794-2 COMPACT CARD

The piston dispersive shock wave problem

February 28, 2008
Author(s)
Mark Hoefer, Mark J. Ablowitz, Peter Engels
The one-dimensional piston shock problem is a classical result of shock wave theory. In this work, the analogous dispersive shock wave (DSW) problem for a dispersive fluid described by the nonlinear Schr?odinger equation is analyzed. Asymptotic solutions

Broadband Permittivity Measurements of Thin-Film Ferroelectrics to 40 GHz

February 25, 2008
Author(s)
Nathan D. Orloff, James C. Booth, Makoto Murakami, Ichiro Takeuchi
We demonstrate a novel experimental technique to measure the complex permittivity function of dielectric thin films over the frequency range from 100 Hz to 40 GHz. We apply this technique to determine the broadband permittivity function for ferroelectric

Modeling the Effect of Finite Size Gratings on Scatterometry Measurements

February 25, 2008
Author(s)
Elizabeth Kenyon, Michael W. Cresswell, Heather Patrick, Thomas Germer
The interpretation of scatterometry measurements generally assumes that the grating extends over an area large enough to intercept all the illumination provided by an incident beam. However, in practice, the grat-ings used in scatterometry are relatively

Overview of the TREC 2006 Enterprise Track

February 25, 2008
Author(s)
Ian M. Soboroff, Arjen de Vries, Nick Craswell
The goal of the enterprise track is to conduct experiments with enterprise data --- intranet pages, email archives, document repositories --- that reflect the experiences of users in real organizations, such that for example, an email ranking technique
