JSR 32 : The JAIN-SIP 1.1 Specification Maintenance Lead

October 1, 2005
Author(s)
Mudumbai Ranganathan
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Knowledge-Intensive Collaborative Decision Support for Design Process

October 1, 2005
Author(s)
XuanFang Zha, Ram D. Sriram
In this chapter, we describe a hybrid decision model and a multi-agent framework for collaborative decision support in the design process. The proposed knowledge-based collaborative decision support model can quantitatively incorporate qualitative design

Linear Stability of Cylindrical Couette Flow in the Convection Regime

October 1, 2005
Author(s)
M E. Ali, Geoffrey B. McFadden
Instability of steady circular Couette flow with radial heating across a vertically oriented annulus with inner cylinder rotating and outer cylinder stationary is investigated using linear stability analysis. The convection regime base flow is developed

Link Variability Studies

L T. Klein-berndt, Michael R. Souryal, Leonard E. Miller, Nader Moayeri
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Macroscopic Dynamics in Large-Scale Data Networks

October 1, 2005
Author(s)
J Yuan, Kevin L. Mills
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Modeling the Formation and Dynamics of Polycrystals in 3D

October 1, 2005
Author(s)
R Kobayashi, James A. Warren
Phase field models of solidification have been extended to include grain boundaries, using a variety of techniques. A model developed by Kobayashi et. al cite} has been used to model a host of physical phenomena, but has so far been confined to two

MPEG-7: Standard Metadata for Multimedia Content

October 1, 2005
Author(s)
Wo L. Chang
The XML metadata technology of describing media contents has emerged as a dominant mode of making media searchable both for human and machine consumptions. To realize this promise, many online Web applications are pushing this concept to its full potential

Non-Markovian Dynamics in a Dense Potassium Vapor

October 1, 2005
Author(s)
Virginia O. Lorenz, Steven T. Cundiff
Transient four wave mixing experiments on a dense potassium vapor with a dephasing time large compared to the collision duration reveal a clear transition from non-Markovian to Markovian dynamics. Theoretical fits using a Gaussian Markov stochastic

Novelty Detection: The TREC Experience

October 1, 2005
Author(s)
Ian M. Soboroff, Donna K. Harman
A challenge for search systems is to detect not only when an item is relevant to the user's information need, but also when it contains something new which the user has not seen before. In the TREC novelty track, the task was to highlight sentences

Overview of the Face Recognition Grand Challenge

October 1, 2005
Author(s)
P J. Phillips, P J. Flynn, W T. Scruggs, K W. Bowyer, J S. Chang, K Hoffman, J Marques, J Min, W Worek
Over the last couple of years, face recognition researchers have been developing new techniques, such as recognition from three-dimensional and high resolution imagery. These developments are being fueled by advances in computer vision techniques, computer

Performance Analysis of Low Rate Wireless Technologies for Medical Applications

October 1, 2005
Author(s)
Nada T. Golmie, David E. Cypher, O Rebala
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Preparation and Flame Resistance Properties of Revolutionary Self-Extinguishing Epoxy Nanocomposites Based on Layered Double Hydroxides

October 1, 2005
Author(s)
Mauro Zammarano, Massimiliano Franceschi, S Bellayer, Jeffrey W. Gilman, Sergio Meriani
Layered double hydroxides/epoxy nanocomposites (LDHs/EP) were prepared from organo modified LDHs, a diglycidyl ether of bisphenol A monomer (DGEBA) and amine curing agents. The organomodified LDHs were obtained by ionic exchange of a magnesium-aluminum

Propagation and Detection of Radio Signals Before, During, and After the Implosion of a Large Sports Stadium (Veterans Stadium in Philadelphia)

October 1, 2005
Author(s)
Christopher L. Holloway, Galen H. Koepke, Dennis G. Camell, Catherine A. Remley, Dylan F. Williams, Susan A. Schima, Seturnino Canales
In this report, we investigate radio communications problems faced by emergency responders (firefighters and police) in disaster situation such as collapsed buildings. A fundamental challenge to communications into and out of large buildings is the strong

Protection Switching for Optical Bursts Using Segmentation and Deflection Routing

October 1, 2005
Author(s)
David W. Griffith, Kotikalapudi Sriram, Nada T. Golmie
Burst segmentation in OBS networks can significantly reduce the amount of data that is lost due to contention events by dropping or deflecting only the portion of a burst that overlaps another contending burst. In this letter, we demonstrate how

Proximity effects in the calibration of microwave radiometers

October 1, 2005
Author(s)
Ronald C. Wittmann, Amanda Cox, Randy Direen
Microwave, total-power radiometers are calibrated by observing sources of known brightness temperature. Free-space calibrations are usually performed assuming far-field interactions, although the actual calibration source may be well into the near-field
