In this paper we construct IR n-valued biorthogonal, compactly supported multiwavelet families such that one of the biorthogo-nal pairs consists of divergence-free vector wavelets. The construction is based largely on Lemari e's idea of multiresolution analyses intertwined by diierentiation. We show that this technique extends nontrivially to multiwavelets via Strela's two-scale transform. An e...

This paper gives an overview of recent achievements of the multiwavelet theory. The construction of multiwavelets is based on a multiresolution analysis with higher multiplicity generated by a scaling vector. The basic properties of scaling vectors such as L-stability, approximation order and regularity are studied. Most of the proofs are sketched.

Orthogonal wavelet bases have been developed using multiple mother wavelet functions. Applying the discrete multiwavelet transform requires the input data to be preprocessed to obtain a more economical decomposition. Four characteristics of a preprocessing method are presented: length, degree, orthogonality and frequency response. A minimal preelter is deened to have length one and highest atta...

due to the different nature of the production structure in economic sectors, growth in these sectors has a different effect on employment. on the other hand, according to market analysis by gender, the impact on job creation in economic sectors is also different for men and women. in this paper, we use social accounting matrix (sam) model for iran to assess how growth in various sectors of the ...

In modern high performance computers there is a trend towards a hybrid architecture. This hybrid architecture features distributed nodes, each of which contains multiple cores, over which memory is shared. A current challenge in HPC (High Performance Computing) is to find solutions which make the best possible use of hybrid architectures. One possible solution is the use of PGAS (Partitioned Gl...

Multiplication is a basic operation in any signal processing application. Multiplication is the most important one among the four arithmetic operations like addition, subtraction, and division. Multipliers are usually hardware intensive, and the main parameters of concern are high speed, low cost, and less VLSI area. The propagation time and power consumption in the multiplier are always high. ...
