Variational Approach in Wavelet Framework to Polynomial Approximations of Nonlinear Accelerator Problems [PDF]
, 1998 In this paper we present applications of methods from wavelet analysis to polynomial approximations for a number of accelerator physics problems. According to variational approach in the general case we have the solution as a multiresolution (multiscales)

A wavelet analysis of the Rosenblatt process: chaos expansion and estimation of the self-similarity parameter [PDF]
, 2010 By using chaos expansion into multiple stochastic integrals, we make a wavelet analysis of two self-similar stochastic processes: the fractional Brownian motion and the Rosenblatt process.

Nonhomogeneous Wavelet Systems in High Dimensions [PDF]
, 2010 It is of interest to study a wavelet system with a minimum number of generators. It has been showed by X. Dai, D. R. Larson, and D. M. Speegle in [11] that for any $d\times d$ real-valued expansive matrix M, a homogeneous orthonormal M-wavelet basis can ...

Wavelet design by means of multi-objective GAs for motor imagery EEG analysis [PDF]
, 2011 Wavelet-based analysis has been broadly used in the study of brain-computer interfaces (BCI), but in most cases these wavelet functions have not been designed taking into account the requirements of this field.
