MEHRBANPhysics Department, Semnan University, Semnan, I. R. of IranM. SAYAHIPhysics Department, Semnan University, Semnan, I. R. of IranJournal Article20141127Using QCD factorization for the hadronic matrix elements, we show that existing data, in<br />particular the branching ratios BR ( B →J/ψK) and BR ( B →J/ψπ), can be accounted for in this approach.<br />We analyze the decay B J /K( ) within the framework of QCD factorization. The calculation of the<br />relevant hard-scattering kernels for twist-2 and twist-3 is completed. We calculate this decay in a special scale<br />( mb ) and in two schemes for Wilson coefficients in NLO. We consider three functions for J / . The<br />twist-3 contribution involves the logarithmically divergent integral, we consider H 0 the canceling<br />divergent. The obtained results are in agreement with available experimental data.http://ijsts.shirazu.ac.ir/article_2179_382ae7c78eb8fff892e5ab88b10b2907.pdfSpringerIranian Journal of Science and Technology (Sciences)1028-627634420101201SUBORBITAL GRAPHS FOR A SPECIAL SUBGROUP OF THE NORMALIZER OF m305312218010.22099/ijsts.2010.2180ENS.

R. of IranJournal Article20100420The most current pursuit algorithms for moving targets which are presented so far in the literature<br />are Pure Pursuit and Pure Rendezvous navigations. Recently, one of the present authors has introduced a<br />geometric model for the Pure Pursuit navigation algorithm. Here, in this paper, we study a new algorithm for<br />the pursuit navigation problem which is a combination of both of the above algorithms. We study its<br />geometric properties, as well as the trajectories as time optimal paths. Finally, we compare this algorithm with<br />well-known algorithms in some real examples.http://ijsts.shirazu.ac.ir/article_2181_4bef8db34f486819627026bcbe6f6e61.pdfSpringerIranian Journal of Science and Technology (Sciences)1028-627634420101201TWO-DIRECTION POLY-SCALE REFINEMENT EQUATIONS WITH NONNEGATIVE COEFFICIENTS321334218210.22099/ijsts.2010.2182ENS.
