Abstract: The classification of human activity using radar has gained considerable attention in recent years because of the radar sensor’s resistance to harsh settings. However, when using machine ...

The Evolutionary Power Spectral Density (EPSD) [1] is compared to the well-known spectrogram implemented in Matlab. The EPSD produces a smoother signal, especially if the amount of data point is low.

Human inventions, namely engineered systems, have relied on fundamental discoveries in physics and mathematics, e.g., Maxwell’s equations, Quantum mechanics, Information theory, etc., thereby applying ...

Abstract: It has been shown that speech spectrograms can be read by trained experts. In this work, we regard the speech spectrogram image as a written text in some unknown language and perform ...

In order to achieve the highly efficient and accurate identification of fracture modes including tension or shear fractures during rock failure, an intelligent identification method based on ...

MISARA (Matlab Interface for Seismo-Acoustic aRray Analysis) is a open-source Matlab-based GUI designed to perform analyses of seismic and acoustic waveform data. A suite of well-established ...

Passive acoustic monitoring (PAM) is increasingly being adopted as a non-invasive method for the assessment of ocean ecological dynamics. PAM is an important sampling approach for acquiring critical ...

This article explains spectrogram of the speech signal (analysis and processing) with MATLAB to get its frequency-domain representation. In real life, we come across many signals that are variations ...
