We introduce another view of group theory in the field of interconnection networks. With this approach it is possible to specify application specific network topologies for permutation data transfers. Routing of data transfers is generated and all possible permutation data transfers are guaranteed. We present the approach by means of a kind of SIMD DSP.

Independent component analysis (ICA) in the frequency domain is used for solving the problem of blind source separation (BSS). However, this method has some problems. For example, a general ICA algorithm cannot determine the permutation of signals which is important in the frequency domain ICA. In this paper, we propose an approach to the solution for a permutation problem. The idea is to effec...

This paper proposes a new approach for image encryption using a combination of different permutation techniques. The main idea behind the present work is that an image can be viewed as an arrangement of bits, pixels and blocks. The intelligible information present in an image is due to the correlations among the bits, pixels and blocks in a given arrangement. This perceivable information can be...

Algorithm 3 details the process for incrementally computing term (13) for all xk. (The process for computing (14) is similar.) Computation of the full gradient is thus also an O(nm) operation. Using this technique, we can apply full-gradient first-order methods efficiently, including gradient projection and Frank-Wolfe. With an appropriate line-search method, gradient projection is guaranteed t...

This chapter describes the mass univariate approach to the analysis of ERP data and the related permutation approach. The mass univariate approach is a powerful way of dealing with the problem of multiple comparisons. It was pioneered in neuroimaging research, where the problem of multiple comparisons is so obvious that it is always explicit rather than implicit. In early neuroimaging studies, ...

A special class of cubic graphs are the cycle permutation graphs. A cycle permutation graph Pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.In this paper we determine a good upper bound for tenacity of cycle permutation graphs.

In this paper, a mixed-integer linear programming model is proposed to integrate batch picking and distribution scheduling problems in order to optimize them simultaneously in an order picking warehouse. A tow-phase heuristic algorithm is presented to solve it in reasonable time. The first phase uses a genetic algorithm to evaluate and select permutations of the given set of customers. The seco...
