Joint time-frequency scattering takes wavelet time scattering one step further and creates a feature extractor that mimics the full cortical model. The second-order scattering coefficients depend onμ, the center frequencies of the second-order time wavelets,ψ(2)μ(t).To account for the time-fr...

This example shows how to classify musical instruments using joint time-frequency scattering features paired with a 3-D convolutional network. JTFS features demonstrate a significant advantage over the raw time series data, the power spectra, and the short-time Fourier transform in correctly ...
The scattering phenomenology in dielectric-coated wire structure is investigated using the joint time-frequency processing of simulated and measurement data. The method of moments is applied to carry out the simulation. The computed results are compared to measured data in both the frequency and time...
In this paper, a novel signal processing for the new mode of FSR system based on the signal's joint time-frequency is proposed and discussed. Additionally, the concept of the FSR system with the rotational transmitter is analyzed experimentally for the detection and localization of a stationary ...
Detection of fracture properties can be implemented using azimuth-dependent seismic inversion for optimal model parameters in time or frequency domain. Considering the respective potentials for sensitivities of inversion resolution and anti-noise perform
but the forward production speed of the work is of course reduced as the frequency and amplitude of the wave form is increased. Moreover, the higher the frequency the greater will be the heat input into the work as can be seen by the different heat bands inFig. 6.8. To produce suchweld...
Our research begins with the rock physics numerical modeling to verify the reliability of ignoring the influence of frequency on velocities. The reflection coefficient approximate formulas of PPwave and PSVwave are derived using scattering function, and these formulas can be applied in the inversion ...
