In this project, we will discuss what sound is, how to represent it mathematically & in a computer, and how to examine its frequency content using Fourier analysis. We will use SageMath along the way ...
A practical step-by-step guide to wavelet analysis is given, with examples taken from time series of the El Niño-Southern Oscillation (ENSO). The guide includes a comparison to the windowed Fourier ...
Abstract: The Ricker and Gabor wavelets and their Hilbert transforms (HTs) are widely used in many physical/engineering fields. In seismology, they are commonly utilized to describe source functions ...
Abstract: This work presents the construction of a novel spherical wavelet basis designed for incomplete spherical datasets, i.e. datasets which are missing in a particular region of the sphere. The ...
