Abstract: In seismic inversion, the subsurface model can be parameterized by a truncated Fourier series, and then, the inversion problem is the inversion of the Fourier coefficients. To improve the ...

Abstract: We propose the Wasserstein-Fourier (WF) distance to measure the (dis)similarity between time series by quantifying the displacement of their energy across frequencies. The WF distance ...

Problem 1: Implementing the FFT radix 2 algorithm using built in matlab fft() function. myfft32.m is the implementation of the problem. It is meant to be called out with a 32-sample input function x, ...

The elastic wave attenuation in artificial composites, known as phononic crystals (PnCs), is an important topic in the context of wave manipulation. However, there is a lack of knowledge in the ...
