Wavelet analysis of temporal data [PDF]

open access: yes, 2008
This thesis considers the application of wavelets to problems involving multiple series of temporal data. Wavelets have proven to be highly effective at extracting frequency information from data.

Wavelet-Based High-Order Adaptive Modeling of Lossy Interconnects [PDF]

open access: yes, 2001
—This paper presents a numerical-modeling strategy for simulation of fast transients in lossy electrical interconnects. The proposed algorithm makes use of wavelet representations of voltages and currents along the structure, with the aim of reducing the

Multiscale texture classification using dual-tree complex wavelet transform [PDF]

open access: yes, 2009
This paper presents a multiscale texture classifier that exploits the Gabor-like properties of the dual-tree complex wavelet transform, shift invariance and six directional subbands at each scale, and uses a feature vector comprising of a variance and an

Penalized wavelet monotone regression [PDF]

open access: yes, 2007
In this paper we focus on nonparametric estimation of a constrained regression function using penalized wavelet regression techniques. This results into a convex op- timization problem under linear constraints.

Wavelet-Based Adaptive Solution for the Nonuniform Multiconductor Transmission Lines [PDF]

open access: yes, 1998
—A time-domain technique for the solution of arbi-trary nonuniform multiconductor transmission lines (NMTL’s) is presented. The technique is based on a weak formulation of the NMTL equations obtained through spatial expansion of the voltage and current ...

An Application to Transient Current Signal based Induction Motor Fault Diagnosis of Fourier-Bessel Expansion and Simplified Fuzzy ARTMAP [PDF]

open access: yes, 2013
The start-up transient signals have been widely used for fault diagnosis of induction motor because they can reveal early defects in the development process, which are not easily detected with the signals in the steady state operation. However, transient

Multiresolution-based image fusion with additive wavelet decomposition [PDF]

open access: yes, 1999
The standard data fusion methods may not be satisfactory to merge a high-resolution panchromatic image and a low-resolution multispectral image because they can distort the spectral characteristics of the multispectral data.

Wavelet Estimators in Nonparametric Regression: A Comparative Simulation Study [PDF]

open access: yes, 2001
Wavelet analysis has been found to be a powerful tool for the nonparametric estimation of spatially-variable objects. We discuss in detail wavelet methods in nonparametric regression, where the data are modelled as observations of a signal contaminated ...
