Abstract: Spherical measurement is a relatively important application in optical measurement. The interferogram obtained in spherical inspection usually consists of closed fringe patterns. Obtaining ...

One year ago, Sam Altman, the C.E.O. of OpenAI, made a bold prediction: “We believe that, in 2025, we may see the first AI agents ‘join the workforce’ and materially change the output of companies.” A ...

The prediction of the properties of crystal materials has always been a core issue in materials science and solid-state physics. With the rapid development of computer simulation techniques and ...

Abstract: Many real-world networks are characterized by directionality; however, the absence of an appropriate Fourier basis hinders the effective implementation of graph signal processing techniques.

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

Morrison Heights Baptist Church has a refreshingly current take underlying its traditional services. Its otherwise conventional worship style, complete with an instrumental mixture of traditional ...

As you can see, the frequencies are cut and this leads to out_ft. Then, this should be the input argument of the irfft2, however, X (which is the Fourier transform of the original data) is given. This ...

In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...
