design methods for paraunitary matrices from complete orthogonal sets of idempotents and related matrix structures are presented. these include techniques for designing non-separable multidimensional paraunitary matrices. properties of the structures are obtained and proofs given. paraunitary matrices play a central role in signal processing, in particular in the areas of filterbanks and wavelets.
Intra-query parallelism is a well-established mechanism for achieving high performance in (object-) relational database systems. However, the methods have yet not been applied to the upcoming field of multidimensional array databases. Specific properties of multidimensional array data require new parallel algorithms. This paper presents a number of new techniques for parallelizing queries in mu...
This paper investigates the k-mixing property of a multidimensional cellular automaton. Suppose F is a cellular automaton with the local rule f defined on a d-dimensional convex hull C which is generated by an apex set C. Then F is k-mixing with respect to the uniform Bernoulli measure for all positive integer k if f is a permutation at some apex in C. An algorithm called the Mixing Algorithm i...
Purpose: The purpose of this research was to investigate the psychometric properties of Persian version of the multidimensional body-self relations questionnaire (MBSRQ) among Iranian elderly people. Methods & Materials: The research method was non-experimental research that its necessary information was collected with cross-sectional method. The statistical population was composed of all el...
The present research was aimed to investigate the reliability and validity for Brief Multidimensional Students Life Satisfaction Scale (BMSLSS) in Iranian students. All the high school girls and boys in 8th and 15th Tehran regions were selected as statistical population from which 736 students were selected as a sample to study, by using cluster sampling method. Brief Multidimensional Student...
Abstract In this paper, it is shown that for a minimal system ( X , G ), if H normal subgroup of with finite index n then can be decomposed into components closed sets such each component under -action. Meanwhile, we prove residual set points in finitely many commuting homeomorphisms, the return times to any non-empty open contains arbitrarily long geometric progressions multidimension, extendi...
