Wavelet-induced renormalization group for the Landau-Ginzburg model [PDF]

open access: yes, 1999
The scale hierarchy of wavelets provides a natural frame for renormalization. Expanding the order parameter of the Landau-Ginzburg/$\Phi^4$ model in a basis of compact orthonormal wavelets explicitly exhibits the coupling between scales that leads to non-

Fourier–Boas-Like Wavelets and Their Vanishing Moments

open access: yesJournal of Mathematics, 2021
In this paper, we propose Fourier–Boas-Like wavelets and obtain sufficient conditions for their higher vanishing moments. A sufficient condition is given to obtain moment formula for such wavelets. Some properties of Fourier–Boas-Like wavelets associated

Design and Implementation of New Biorthogonal Wavelets and its Application to Image Processing

open access: yesInternational Journal of Emerging Research in Engineering, Science, and Management, 2022
Wavelet transformation has been an interesting field since its exposure with wavelet-based compression standard embedded zerotree wavelet. Though, the origin of wavelets back to many decades, the presence of research at the very beginning of wavelet ...

Wavelets and their use [PDF]

open access: yes, 2001
This review paper is intended to give a useful guide for those who want to apply discrete wavelets in their practice. The notion of wavelets and their use in practical computing and various applications are briefly described, but rigorous proofs of ...

On The Continuous Steering of the Scale of Tight Wavelet Frames

open access: yes, 2015
In analogy with steerable wavelets, we present a general construction of adaptable tight wavelet frames, with an emphasis on scaling operations. In particular, the derived wavelets can be "dilated" by a procedure comparable to the operation of steering ...

Some results on generalization $\alpha-$Chebyshev wavelets [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, we introduce  generalized formulae for well-known functions such as $\alpha$-Chebyshev functions. We define $\alpha-$Chebyshev wavelets approximation and  generalization $\alpha-$wavelet coapproximation.

A Note on Some New Generalized Wavelets

open access: yesJournal of Mathematics, 2022
In this paper, we define new real wavelets based on the Hartley kernel and Boas transforms. These wavelets have possible application in analyzing both the symmetries of an asymmetric real signal.

Generalized Morse Wavelets as a Superfamily of Analytic Wavelets

open access: yes, 2012
The generalized Morse wavelets are shown to constitute a superfamily that essentially encompasses all other commonly used analytic wavelets, subsuming eight apparently distinct types of analysis filters into a single common form.

Epileptic seizures detection based on some new Laguerre polynomial wavelets, artificial neural networks and support vector machines

open access: yesInformatics in Medicine Unlocked, 2019
Electroencephalography (EEG) is noninvasive and it is an effective tool to understand the complex nature of the brain. Its analysis by visual inspection is tedious and costly, and that is why many researchers in recent years resort to the use of computer-

Chebyshev Wavelet Analysis

open access: yesJournal of Function Spaces, 2022
This paper deals with Chebyshev wavelets. We analyze their properties computing their Fourier transform. Moreover, we discuss the differential properties of Chebyshev wavelets due to the connection coefficients.
