Negative feedback can create a control system where the output of a process is used to counteract any deviations from a desired set point, effectively “correcting” the system, bringing it back to ...
The selection of imaging conditions is one of the most critical factors determining the quality of reverse time migration (RTM) images. Among the widely used imaging conditions, the cross-correlation ...

Purpose: To enable 2D Nyquist ghost correction for multi-band interleaved echo-planar imaging (EPI) without reference scan. Methods: 2D phase errors between positive and negative echo were directly ...
Abstract: In the literature, Bode plots and Nyquist diagrams are used extensively in stability analysis for admittance-based models. In this letter, we demonstrate that eigenvalues obtained from the ...
An editor of a technical magazine once told me that subject matter recirculates every eight months as a method of informing an ever-changing audience. It’s been a while since I addressed Bode plots as ...
Abstract: Multivariable Nyquist eigenloci provide a much richer family of curves as compared to the SISO case. The eigeloci may be computed symbolically in many simple cases. Inspection of the ...
