We extend the classic results of paper [P. C. W. Davies, S. A. Fulling, and G. Unruh, Phys. Rev. D 13, 2720 (1976).] ``Energy-momentum tensor near an evaporating black hole'' by considering a massive scalar field in two dimensions presence thin shell collapse. show that outside WKB approximation is valid for any value $r$ if $m{r}_{g}\ensuremath{\gg}1$, where $m$ mass field, ${r}_{g}$ Schwarzsc...

In this paper we restrict every set splitting problem to the special case in which every set has just three elements. This restricted version is also NP-complete. Then, we introduce a general conversion from any set splitting problem to 3-set splitting. Then we introduce a randomize algorithm, and we use Markov chain model for run time complexity analysis of this algorithm. In the last section ...

Abstract Case cutting has been demonstrated as a means of warhead self-destruction, but few studies have analyzed it in detail. Based on the self-destruction ammunition, effect shell split including fragmentation and scattering characteristics driven by charge detonation were studied. The results show that splitting warhead, can be hardly broken, scatter form large-size splits. velocity fragmen...

the aim of this study is investigation on effect of stem end splitting and geranium essential oil on vase life on quality of cut chrysanthemum (dendranthema grandiflorum l.). this experiment arranged as factorial based on rcd with 2 factors of stem end splitting at 2 levels (with splitting and without splitting) and geranium essential oil at 6 levels (0, 1, 2, 4, 8 and 10 %), with 12 treatments...
