Coarse-graining and the Haar wavelet transform for multiscale analysis [PDF]
Bioelectronic Medicine, 2022 Background Multiscale entropy (MSE) has become increasingly common as a quantitative tool for analysis of physiological signals. The MSE computation involves first decomposing a signal into multiple sub-signal ‘scales’ using a coarse-graining algorithm ...

The Haar wavelet characterization of weighted Herz spaces and greediness of the Haar wavelet basis
Journal of Mathematical Analysis and Applications, 2010 The authors study the class of dyadic \(A_p\)-weights in connection with dyadic maximal operators (where in both cases on considers dyadic cubes only) and show that one obtains results corresponding to the ones one gets for the usual \(A_p\)-weights and maximal operators.
