Witrynagraph-based approach for local coherence modeling. We evaluate our system on three tasks: sentence ordering, summary coherence rating and readability assess-ment. The performance is comparable to entity grid based approaches though these rely on a computationally expensive train-ing phase and face data sparsity problems. 1 … Witryna19 kwi 2010 · Local phase coherence (LPC) is a recently discovered property that reveals the phase relationship in the vicinity of distinctive features between …

WitrynaHere we propose a new sharpness measure where sharpness is identified as strong local phase coherence evaluated in the complex wavelet transform domain. Our test using the LIVE blur database shows that the proposed algorithm correlates well with subjective quality evaluations. An additional advantage of our approach is that other … WitrynaRandom fluctuations of the local magnetic field lead to random variations in the instantaneous NMR precession frequency of different spins. As a result, the initial phase coherence of the nuclear spins is lost, until eventually the phases are disordered and there is no net xy magnetization. if she ever call my phone i decline

WitrynaFigure 1: A prism is inserted into a spatially coherent laser beam, generating an interference pattern on the screen. There are two very different aspects of coherence: Spatial coherence means a strong correlation (fixed phase relationship) between the electric fields at different locations across the beam profile. For example, within a … Witryna11 kwi 2024 · Cortical information processing is thought to be facilitated by the resonant properties of individual neurons and neuronal networks, which selectively amplify inputs at specific frequencies. We used optogenetics to test how different input frequencies are encoded by excitatory cells and parvalbumin-expressing (PV) interneurons in mouse … WitrynaA. L. Latifah and E. van Groesen: Localized coherence of freak waves 343 describe the wavelet transform that is used in this paper to ex-tract the local energy spectral distribution and the local phase as the time–frequency information of a given signal. Plots of the energy distribution over the frequencies will show that if sheets vba
