Abstract: Fourier Transform (FT) is an important signal processing technique that translates time-domain signals to frequency-domain forms. It is widely used in several applications, including 5G ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...

The implementation of jax.numpy.fft.fftfreq now requires real dtype, starting in jax v0.6.1. Previously it allowed complex dtypes. There is an obvious workaround to call astype() afterward (and the ...

For numpy.fft.fftn and numpy.fft.ifftn, individual FFTs over axes are performed in reverse order. Similarly, for numpy.fft.rfftn, individual FFTs are performed in reverse order. However, for numpy.fft ...

This paper introduces a new encryption method aimed at improving the cryptography process through the use of splitting radix Fourier Transform technique called Split-Radix Fast Fourier Transforms ...

Abstract: Given a template image T, the task in template matching is to search for T in a larger image region S. While simple in concept, much effort in recent years has been channeled on improving ...

ABSTRACT: In this paper, we perform a comprehensive explanation of the geophysical inversion of gravity data, as well as, how it can be used to determine the Moho undulation and the crustal structure.
