It is now possible to calculate the Fourier transform of an image on your smartphone, thanks to a new app developed by two nanophotonics researchers in The Netherlands. “2D-Fourier” is available for ...

A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...

The residency features a total of 52 performances, offering fans an immersive experience of the band’s music. The process of ...

The notion of Fourier transform is among the most important tools in analysis, which has been generalized in abstract harmonic analysis to the level of abelian locally compact groups. The aim of this ...

Oftentimes in computing, we start doing a thing, and we’re glad we’re doing it. But then we realise, it would be much nicer if we could do it much faster. [Ricardo de Azambuja] was in just such a ...

Reviews ordinary differential equations, including solutions by Fourier series. Physical derivation of the classical linear partial differential equations (heat, wave, and Laplace equations). Solution ...

The Fast Fourier Transform (FFT) is an implementation of the Discrete Fourier Transform (DFT) using a divide-and-conquer approach. A DFT can transform any discrete signal, such as an image, to and ...

This is a preview. Log in through your library . Abstract For any $0 < \alpha < \frac{1}{2}$ we construct a sequence of integers (μ1,..., μn,...) such that the ...
