Author(s)
N Dao, I Dumitru, L Spinu, S L. Whittenburg, Michael J. Donahue, J C. Lodder
We have calculated dynamic susceptibility of patterned cobalt and Permalloy pillars with a diameter of 50 nm and different pillar heights using micromagnetic simulations. The resonance modes obtained from these simulations are compared to the results

Embedding MPEG-7 Metadata Within a Media File Format

October 1, 2005
Author(s)
Wo L. Chang
Embedding metadata within a media file format becomes evermore popular for digital media. Traditional digital media files such as MP3 songs and JPEG photos do not carry any metadata structures to describe the media content until these file formats got

Enhanced Quantum State Detection Efficiency Through Quantum Information Processing

October 1, 2005
Author(s)
T Schaetz, M D. Barrett, D. Leibfried, J. Britton, J. Chiaverini, W M. Itano, J. D. Jost, Emanuel Knill, C. Langer, David J. Wineland
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

Face Recognition Based on Frontal Views Generated from Non-Frontal Images

October 1, 2005
Author(s)
V Blanz, Patrick Grother, P. Jonathon Phillips, T Vetter
This paper presents a method for face recognition across large changes in viewpoint. Our method is based on a Morphable Model of 3D faces that represents face-specific information extracted from a dataset of 3D scans. For non-frontal face recognition in 2D

Factors Affecting Development of a Motion Imagery Quality Metric

October 1, 2005
Author(s)
Charles D. Fenimore, J Irvine, D Cannon, John W. Roberts, S Israel, L Simon, C Watts, J Miller, A Aviles, P F. Tighe, R J. Behrens
The motion imagery community would benefit from the availability of standard measures for assessing image interpretability. The National Imagery Interpretability Rating Scale (NIIRS) has served as a community standard for still imagery, but no comparable

Fracture Strength of Silicon Carbide Microspecimens

October 1, 2005
Author(s)
W N. Sharpe, O Jadaan, G M. Beheim, George D. Quinn, N N. Nemeth
Micro silicon carbide tension specimen were prepared with straight, curved, and notched gage lengths. These were tested to failure and the strengths analyzed by Weibull statistics. Fractographic analysis confirmed that strength limiting flaws were etch

Group-Based Ad-hoc Network for Multimedia Communications

October 1, 2005
Author(s)
K Ban, Hamid Gharavi
This paper is concerned with evaluating ad-hoc networks for group-oriented tactical operations. For such operations, a cellular-based ad-hoc network architecture has been constructed for real-time multimedia communications. To assess the suitability of

Guaranteed Quality of Recovery in WDM Mesh Networks
