A note on a practical relationship between filter coefficients and scaling and wavelet functions of Discrete Wavelet Transforms
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
In this paper, the relationship between the filter coefficients and the scaling and wavelet functions of the Discrete Wavelet Transform is presented and exemplified from a practical point-of-view. The explanations complement ...
Wavelet-galerkin method for computations of electromagnetic fields-computation of connection coefficients
(Institute of Electrical and Electronics Engineers (IEEE), 2000-12-01)
One of the key issues which makes the waveletGalerkin method unsuitable for solving general electromagnetic problems is a lack of exact representations of the connection coefficients. This paper presents the mathematical ...
Multiscale Analysis of GPS Time Series from Non-decimated Wavelet to Investigate the Effects of Ionospheric Scintillation
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2015-08-01)
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 ...
Dual-tree complex wavelet transform applied to fault monitoring and identification in aeronautical structures
(2014-01-01)
This paper proposes the application of the dual-tree complex wavelet transform on fault monitoring and identification in aeronautical structures. For this purpose, a multiscale analysis from phase of the complex wavelet ...
Non-decimated Wavelet Transform for a Shift-invariant Analysis
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2018)
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 ...
Partial discharge location in power transformer windings using the wavelet Laplace function
(Elsevier Science Sa, 2014-06)
Insulation system conditions in power transformers can be evaluated by means of partial discharge (PD) analyses. In fact, PD analysis is used to detect premature damage in transformer insulation system to avoid catastrophic ...
