E-Government Security Issues and Measures

December 30, 2005
Author(s)
William C. Barker
The Handbook will be a three-volume, 2,400-page reference source providing state-of-the-art information concerning the information, computer and network security with coverage of the core topics. The audience is four-year colleges and universities with

Multiscale Modeling of Germanium Quantum Dots in Silicon

December 30, 2005
Author(s)
Vinod Tewary, David T. Read
A method is described for multiscale modeling of a quantum dot in a semiconductor containing a free surface. The method is based upon the use of the lattice-statics and continuum Green's functions integrated with classical molecular dynamics. It fully

Tailored Nanoscale Contrast Agents for Magnetic Resonance Imaging

December 30, 2005
Author(s)
Alexander J. Barker, Brant Cage, Stephen E. Russek, Ruchira Garg, R Shandas, Conrad Stoldt
Two potential molecular imaging vectors are investigated for material properties and magnetic resonance imaging (MRI) contrast improvement. Monodisperse magnetite (Fe 3O 4) nanocrystals ranging in size from 7 to 22 nm are solvothermally synthesized by

Reliability and Performance Limitations in SiC Power Devices

December 27, 2005
Author(s)
Ranbir Singh, Allen R. Hefner Jr.
Despite Silicon Carbide's (SiC's) high breakdown electric field, high thermal conductivity and wide bandgap, it faces certain reliability challenges when used to make conventional power device structures like power MOS-based devices, bipolar-mode diodes

Response Dynamics of the Frequency Comb Output from a Femtosecond Fiber Laser

December 26, 2005
Author(s)
Brian Washburn, William C. Swann, Nathan R. Newbury
The frequency comb from a mode-locked fiber laser can be stabilized through feedback to the pump power. An understanding of the mechanisms and bandwidth governing this feedback is of practical importance for frequency comb design and of basic interest

Single photon source characterization with a superconducting single photon detector

December 26, 2005
Author(s)
Robert Hadfield, Martin Stevens, Stephen Gruber, Aaron J. Miller, Robert E. Schwall, Richard Mirin, Sae Woo Nam
Superconducting single photon detectors (SSPD) based on nanopatterned niobium nitride wires offer single photon counting at fast rates, low jitter, and low dark counts, from visible wavelengths well into the infrared. We demonstrate the first use of an

Dependence of magnetization dynamics on magnetostriction in NiFe alloys

December 23, 2005
Author(s)
Roberto Bonin, Michael Schneider, Thomas J. Silva, John P. Nibarger
We present a quantitative, systematic study of the effect of magnetostriction on the dynamical properties in NiFe alloys. Both the ferromagnetic resonance frequency and the damping times are correlated to the magnetostriction. In addition, we find that the

Electromagnetic Signatures of WLAN Cards and Network Security

December 21, 2005
Author(s)
Catherine A. Remley, Chriss A. Grosvenor, Robert T. Johnk, David R. Novotny, Paul D. Hale, Michael McKinley, Emmanouil Antonakakis, A Karygiannis
The proliferation of wireless devices and the availability of new wireless applications and services raise new privacy and security concerns. Although network-layer anonymity protects the identities of the communication endpoints, the physical layer of

Intrinsic Electronic Conduction Mechanisms in Self-Assembled Monolayers

December 21, 2005
Author(s)
Wenyong Wang, Takhee Lee
A review on the mechanisms and characterization methods of molecu- lar electronic transport is presented. Using self-assembled monolayers (SAMs) of alkanethiols in a nanometer scale device structure, tunneling is unambiguously demonstrated as the main

The History of IDF and its Influences on IR and Other Fields

December 21, 2005
Author(s)
Donna K. Harman
The surprisingly simple IDF measure developed in 1972 by Karen Sparck Jones has continued to dominate the term weighting metrics used in information retrieval, despite several efforts to develop more complex measures of term distribution. It has been
