In this paper, the mathematical model of HIV infection for CD8+ T-cells is illustrated. The homotopy analysis method and the Laplace transformations are combined for solving this model. Also, the convergence theorem is proved to demonstrate the abilities of presented method for solving non-linear mathematical models. The numerical results for $N=5, 10$ are presented. Several $hbar$-c...

Split-hom together structure is a new heavy load rack structure, and its reliability needs to be verified. Through analyzing multimodal hom-connection principle from the perspective of bionics and contact mechanics, the article puts forward three kinds of hom-connection methods and establishes the finite element model and mathematical model of the rack. Afterwards, the finite element model and ...

The purpose of this study was to find out student errors in solving problems about mathematical literacy. This uses a qualitative research approach with sampling method is purposive sampling. subjects were three students who taken based on KAM (Student Initial Ability), namely high, medium, and low ability categories. Each subject one person per category from the Department Accounting, Bandung ...
