網頁2024年2月4日 · This paper proposes a reliable fault diagnosis model for a spherical storage tank. The proposed method first used a blind source separation (BSS) technique to de-noise the input signals so that the signals acquired from a spherical tank under two types of conditions (i.e., normal and crack conditions) were easily distinguishable. BSS split the … 網頁Hi team, I am trying to upgrade PyTorch to 2.0.0+cu118 to support Hopper and come across the following error: RuntimeError: stft requires the return_complex parameter be given for real inputs, and will further require that return_complex...

The Fourier transform (a one-dimensional function) of the resulting signal is taken, then the window is slid along the time axis until the end resulting in a two-dimensional representation of the signal. Mathematically, this is written as: where is the window function, commonly a Hann window or Gaussian window centered around zer…
