Local phase coherence

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 https://kathrynreeves.com

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.

Plot the phase of the cross spectrum and indicate the frequencies with significant coherence between the two times. Mark the known phase lags between the sinusoidal components. At 100 Hz and 200 Hz, the phase lags estimated from the cross spectrum are close to the true values.

WitrynaPseudo-coherent radars are a class of radars. They are also sometimes called “coherent-on-receive radars”. In meteorology, they are referred to as Doppler radars. A requirement for any Doppler radar is coherence; that is, some definite phase relationship must exist between the transmitted frequency and the reference frequency, which is …
