Comparison of Real-Time Water Proton Spectroscopy and Echo-Planar Imaging Sensitivity to the BOLD Effect at 3 T and at 7 T

Frank Scharnowski, Yury Koush

Gradient-echo echo-planar imaging (GE EPI) is the most commonly used approach to assess localized blood oxygen level dependent (BOLD) signal changes in real-time. Alternatively, real-time spin-echo single-voxel spectroscopy (SE SVS) has recently been intro ...

Quality Assessment of Asymmetric Stereo Pair Formed From Decoded and Synthesized Views

Touradj Ebrahimi, Francesca De Simone, Philippe Hanhart

When a stereo pair is formed from a decoded view and a synthesized view, it is unclear how the overall quality of the stereo pair should be assessed through objective quality metrics. In this paper, this problem is addressed considering a 3D video represen ...

Zeta: Scheduling Interactive Services with Partial Execution

James Richard Larus, Sameh Mohamed Elnikety, Chenyu Yan

This paper presents a scheduling model for a class of interactive services in which requests are time bounded and lower result quality can be traded for shorter execution time. These applications include web search engines, finance servers, and other inter ...
