The spatially localized spherical Fourier transform has been studied for various applications in recent years. One of the main arguments of the transform is the window function, typically selected to provide localization in space and to enable spectr

Wigner-Ville distribution (WVD) is an important time-frequency analysis technology with a high energy distribution in seismic signal processing. However, it is interfered by many cross terms. To suppress the cross terms of the WVD and keep the concen

Full waveform inversion and reverse time migration are active research areas for seismic exploration. Forward modeling in the time domain determines the precision of the results, and numerical solutions of finite difference have been widely adopted a

An Intrusion Detection System (IDS) is counter measure against network attack. There are mainly two types of detections; signature-based and anomaly-based. And there are two kinds of error; false negative and false positive. In development of IDS, es

Normally Time-Frequency analysis is done by sliding a window through the time domain data and computing the Fourier Transform of the data within the window. The choice of the window length determines whether specular or resonant information will be e

The short-time linear canonical transform (STLCT), which maps the time domain signal into the joint time and frequency domain, has recently attracted some attention in the area of signal processing. However, its applications are still limited due to
