Wavelets have been placed at the forefront of scientific researches involving signal processing, applied mathematics, pattern recognition and related fields. Nevertheless, as we have observed, students and young researchers ...

This article introduces the third generation of an interesting tool created for time-frequency-shape (TFS) joint analysis. Called Discrete Shapelet Transform (DST-III), it improves both its predecessors, i.e., DST-I and ...

Due to the numerous application possibilities, the theory of wavelets has been applied in several areas of research. The Discrete Wavelet Transform is the most known version. However, the downsampling required for its ...

Due to the ability of time-frequency location, the wavelet transform has been applied in several areas of research involving signal analysis and processing, often replacing the conventional Fourier transform. The discrete ...

This thesis proposes the application of the stationary discrete wavelet packet transform (SDWPT) to properly estimate primary power quantities (active, total apparent, nonactive power, and power factor), and distortion ...

The following article presents the results obtained in experiences that use the Impulse Frequency Response Analysis (IFRA) method with a transformer in service. The IFRA method has been implemented in order to transform ...

In the last decade, the problem of forecasting time series in very different fields has received increasing attention due to its many real-world applications. In particular, in the very challenging case of financial time ...

La inclusión de las redes inalámbricas de sensores y tecnologías IoT (Internet of Things) en ambientes industriales busca el monitoreo y registro autónomo de una mayor cantidad de variables del proceso industrial con una ...
