The role that mobile and wireless network technologies play in the learning process is a critical success factor in our contemporary educational system. These technologies offer unique solutions to specific problems arising from infrastructural limitations in most developing nations.Since these technologies create new awareness and conditions for learning, the problem of what, where, how and when to learned is solved. It is within these context that mobile learning (M-learning) has proved to enhance both learning and teaching environments. In this book, we designed and implemented a mobile...

This work consist of a family of one step rational integrators of order 2k-1 developed for the solution of singular and stiff initial value problems. The integrators derived cope effectively well with stiff and singular initial value problems in ordinary differential equations. The methods in this class of integrators have been shown to be A and L stable. The implementation of the class of integrators on digital computers especially Pentium series was exhaustively analyzed in this work. A package in Fortran 70 was developed for easy implementation of results.
