The wavelet transforms in Gelfand-Shilov spaces [PDF]

open access: yes, 2015
We describe local and global properties of wavelet transforms of ultradifferentiable functions. The results are given in the form of continuity properties of the wavelet transform on Gelfand-Shilov type spaces and their duals. In particular, we introduce

Simulation of Field Theories in Wavelet Representation [PDF]

open access: yes, 1994
The field is expanded in a wavelet series and the wavelet coefficients are varied in a simulation of the 2D $\phi^4$ field theory. The drastically reduced autocorrelations result in a substantial decrease of computing requirements, compared to those in ...

Wavelets and Multigrid

open access: yesSIAM Journal on Scientific Computing, 1993
Some similarities between multiresolution (wavelet) analysis [see \textit{B. Glowinski}, \textit{W. Lawton}, \textit{M. Ravachol} and \textit{E. Tedenbaum}. Wavelet solution of linear and nonlinear elliptic, parabolic and hyperbolic problems in one space dimension, in computing methods in applied sciences and enginneering, Society for Industrial and ...

Wavelets on Fractals

open access: yesRevista Matemática Iberoamericana, 2006
We show that there are Hilbert spaces constructed from the Hausdorff measures \mathcal{H}^{s} on the real line \mathbb{R} with 0 < s < 1 which admit multiresolution wavelets.

Maximum-entropy image reconstruction using wavelets [PDF]

open access: yes, 2003
Wavelet functions allow the sparse and efficient representation of a signal at different scales. Recently the application of wavelets to the denoising of maps of cosmic microwave background (CMB) fluctuations has been proposed. The maximum-entropy method

An overview on preseismic anomalies in LF radio signals revealed in Italy by wavelet analysis

open access: yesAnnals of Geophysics, 2008
Since 1996, the electric field strength of the two broadcasting stations MCO (f=216 kHz, southeast France) and CZE (f=270 kHz, Czech Republic) has been sampled every ten minutes by a receiver (AS) located in central Italy.

Structure and realization of pole-shared switched-current complex wavelet filter [PDF]

open access: yes, 2015
A pole-shared switched-current complex wavelet filter structure with follow-the-leader feedback configuration is proposed for synthesizing the real and imaginary approximation functions with the same poles.

A Terracotta Mold Discovered in Chartres (France, Eure-et-Loir) with Original Iconography for Apollo

open access: yesLes Carnets de l’ACoSt
In this note, we introduce a mold for a terracotta figurine that represents the god Apollo, whose iconography is unprecedented in the products of central Gaul.

Responses of groundwater to precipitation variability and ENSO in the Vietnamese Mekong Delta

open access: yesHydrology Research, 2021
Groundwater is a critical component of water resources and has become the primary water supply for agricultural and domestic uses in the Vietnamese Mekong Delta (VMD).
