Sentence examples for circular approximation from inspiring English sources
Error due to circular approximation of crossbars is quantified and is found to be insignificant.
The meniscus of the bridge is described using a circular approximation, which is reasonable under some conditions.
A simplified solution of dynamic bridge strength based on the superposition of lubrication theory and circular approximation is presented.
Then, a boundary segmentation methodology estimates a circular approximation of the optic disc boundary by applying mathematical morphology, edge detection techniques, and the circular Hough transform.
A simplified model of dynamic bridge strength based on the superposition of lubrication and circular approximation is incorporated in the simulation model.
A simplified model of dynamic bridge strength based on the superposition of lubrication and circular approximation is used in the simulation model.
Based on the analysis above, the circular convolution approximation problem seriously degrades the separation performance in high reverberation.
Besides permutation and scaling ambiguities, another problem also affects the performance of frequency-domain BSS: the STFT circular convolution approximation.
Frequency-domain BSS and its circular convolution approximation problem are introduced in Section 2. The proposed method combining BSS and beamforming is presented in Section 3. Section 4 gives experimental results in various reverberant environments.
The reason is that, BSS can work well alone when the circular convolution approximation problem is not evident in low reverberation, and thus the contribution of preprocessing is small.
On the other hand, when the circular convolution approximation problem become severe in high reverberation, the contribution of preprocessing becomes crucial and hence the separation performance is improved significantly. Figure 12 Average relative performance improvement of the combined method over the BSS-only method in different reverberant environments.
