Abstract: In the arena of education, Cloud computing is more apparent technology to ensure availability and sharing of resources through virtualization. To acquire benefit from this technology boon, it is important for an educational institution to identify the important factors that contribute on cloud computing adoption. So, this study has been conducted to identify the factors that will affect cloud computing adoption in educational sector. University of Dhaka is chosen as a case for this paper. Both primary and secondary sources are used for data collection. Seventeen potential factors are taken into consideration, on which survey has been conducted focusing primary sources. After performing multiple regression, variance inflation factor and factor analysis on data of primary source, six factors are identified as core factors to cloud computing adoption, these are- service availability, cloud control ability, resource need, usefulness in education, lack of proper infrastructure, lack of training of staff. These findings can be used as a theoretical base and future development of technological adoption in higher education.

Abstract: In recent years, it brings lots of challenges for European governments with the influx of refugees. Hence, we build relative models to solve this situation. In this paper, we get relative data from UNHCR statistical yearbook and make a short-term prediction of refugee number via grey GM (1, 1) model at first. Then we select five limited indexes for the multi-objective analysis, in order to build the optimal quota model and get optimal quota plan. Finally, we put forward some feasible suggestions to EU about refugee quota plan on the basis of former analyses.

Abstract: In this paper, mathematical models of immobilized enzyme system that follow the Michaelis-Menten mechanism for both reversible and irreversible reactions are discussed. This model is based on the diffusion equations containing the non-linear term related to Michaelis-Menten kinetics. An approximate analytical technique employing the modified Adomian decomposition method is used to solve the non-linear reaction diffusion equation in immobilized enzyme system. The concentration profile of the substrate is derived in terms of all parameters. A simple expression of the substrate concentration is obtained as a function of the Thiele modulus and the Michaelis constant. The numerical solutions are compared with our analytical solutions for slab, cylinder and spherical pellet shapes. Satisfactory agreement for all values of the Thiele modulus and the Michaelis constant is noted. Graphical results and tabulated data are presented and discussed quantitatively to illustrate the solution.

Abstract: In this paper, new homotopy perturbation method (iteration scheme) will be employed to solve the nonlinear dynamical problems that arise in thin membrane kinetics. More precisely, the method will be used to mathematically model and solve the kinetics of the thin membrane. A main property that makes the proposed method superior to other iterative methods is the way it handles boundary value problems, where both mixed Dirichlet and Neumann boundary conditions are taken into consideration, while other iterative methods only make account of the initial point and as a result, the approximate solution may deteriorate for values that are far away from the initial point and closer to the other endpoint. Our analytical results are compared with numerical solution. The method is found to be easily implemented, fast, and computationally economical and attractive.
