the problem of series two-block disjoint decomposition of completely specifiedboolean functions is considered. analysis and investigation of such systems are veryimportant in logical design context. recently, a good method for solving thisproblem was suggested which has been based on the ternary matrix cover approach.using this method a computer program was developed. this paper is focused onde...

Experience and recent lawsuits have led large internet users to search for ways to filter email and web traffic by content. This paper reviews the prospects for this research for specific domain: pornography. We present results on a particularly challenging image-only database and describe how these image-only methods might be fused with test-based analysis to produce a multimedia system.

In this paper efficient VLSI architectures of highly concurrent algorithms for the solution of block linear systems with Toeplitz or near-to-Toeplitz entries are presented. The main features of the proposed scheme are the use of scalar only operations, multiplications/divisions and additions, and the local communication which enables the development of wavefront array architecture. Both the mea...

We present variants of the block-GMRES(m) algorithms due to Vital and the block-LGMRES(m,k) by Baker, Dennis and Jessup, obtained with replacing the standard QR factorization by a rank-revealing QR factorization in the Arnoldi process. The resulting algorithm allows for dynamic block deflation whenever there is a linear dependency between the Krylov vectors or the convergence of a right-handsid...

In the literature, there exist several studies on symbol-based multigrid methods for solution of linear systems having structured coefficient matrices. particular, convergence analysis such has been obtained in an elegant form case Toeplitz matrices generated by a scalar-valued function. block-Toeplitz setting, that is, where matrix entries are small generic instead scalars, some algorithms hav...
