✦ Synopsis

Wavelet reconstruction almost always reduces to the study of certain algebraic identities for polynomials. Typically, one polynomial is chosen and another is found which satisfies an identity appropriate for the desired wavelet construction. In this paper we explore one such equation and give applications of it to wavelet construction. The specific equation we study here comes to us from our recent work on iterative interpolation by exponentials. Through this equation we strive to unify several related questions concerning wavelet construction and provide in each case considered estimates for the decay of the Fourier transform of both the refinable functions and corresponding wavelets.

In this paper a construction of C 1 -wavelets on the two-dimensional sphere is presented. First, we focus on the construction of a multiresolution analysis leading to C 1 -functions on S 2 . We show refinability of the constructed tensor product generators. Second, for the wavelet construction we em

This paper presents two rapidly convergent methods for the design of two-channel odd degree linear phase FIR banks as well as IIR "lter banks. In both cases, zeros of arbitrary multiplicity are assumed at z"!1, to ensure regularity of the generated wavelet basis. It is shown that in the FIR case, th

The well-known problem of elasticity that may be written as a variational equation [4] has been recently extended to non-linear elastoplastic behaviours [13] giving rise to a class of variational inequalities of second kind [9].

## Abstract A family of finite end filters is constructed using a minimum revisions criterion and based on a local dynamic model operating within the span of a given finite central filter. These end filters are equivalent to evaluating the central filter with unavailable future observations replace
