Because cyberspace and Internet predominate in the life of users, in addition to business opportunities and time reductions, threats like information theft, penetration into systems, etc. are included in the field of hardware and software. Security is the top priority to prevent a cyber-attack that users should initially be detecting the type of attacks because virtual environments are not moni...
template matching is a widely used technique in many of image processing and machine vision applications. in this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to rotation, scale, translation and brightness (rstb) changes. for this purpose, we adopt the idea of ring projection transform (rpt) of image. in the proposed algorithm, two novel s...
introduction spect projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. backscatter constitutes a major part of the scatter contamination in lower energy windows. the current study is an evaluation of the effect of backscatter material on fwhm and image quality investigated by monte carlo simulation. materials and methods simind program...

The Scatter Search (SS) is a deterministic strategy that has been applied successfully to some combinatorial and continuous optimization problems. Cuckoo Search (CS) is heuristic search algorithm which is inspired by the reproduction strategy of cuckoos. This paper presents enhanced scatter search algorithm using CS algorithm. The improvement provides Scatter Search with random exploration for ...
background: there is a worldwide interest in searching for potential and effective medicinal plant candidates against various diseases or disorders. till now, there are number of anti-inflammatory drugs like nsaids are available which showed various adverse effects in our body. to reduce these adverse effects, some of medicinal plants have been experimentally validated. aim: the aim of our immu...
From the process of scatter-gather algorithm explained above, we can easily find the essence of the parallel version of this algorithm is the parallel clustering algorithm used in the scatter phase. Frieder, et al. implements a parallel version of the buckshot clustering algorithm [1]. Their work meets the need of the parallel scatter-gather clustering algorithm pretty well, although we can des...
