I have written a program that reads single-component seismograms from a file and uses an implementation of the Fast Fourier Transform (FFT) algorithm by Cooley and Tukey (1965) alongside numerical ...
Abstract: As a key component of fast Fourier transform (FFT), the complex multiplier (CM) includes twiddle factor generation and corresponding multiplication. This brief proposes an tailored approach ...
CaNS (Canonical Navier-Stokes) is a code for massively-parallel numerical simulations of fluid flows. It aims at solving any fluid flow of an incompressible, Newtonian fluid that can benefit from a ...
Abstract: A novel combination of the conjugate gradient (CG) method with the fast Fourier transform technique (FFT) is presented. With this combination, the computational time required to solve large ...
This article presents two important DSP techniques, the overlap-add method, and FFT convolution. The overlap-add method is used to break long signals into smaller segments for easier processing. FFT ...
Computational homogenization has emerged as an indispensable tool for bridging the gap between the microscale heterogeneity of composite materials and their macroscopic behaviour. By employing ...
Nyström's method with the trapezoidal rule, and the Fourier method, produce the same approximation to the solution of an integral equation at the collocation points ...
