E-learning is not a widespread and accepted concept at Cameroon Universities. In the 1980s, Cameroon has realised distance learning through the School of Agronomy now at the University of Dschang. It consisted of the traditional approach based upon postal services. But since the postal branch has collapsed in Cameroon and the Internet has not yet replaced it, this type of teaching has become le...

The purpose of this project is to create and evaluate a low cost multimedia curriculum tool (hybrid CD-ROM with Internet capabilities) that will assist students, particularly distance education students, to (a) apply and reflect upon what they have learned with instructor support and feedback, and (b) participate in a community of learners who engage in constructive problem-solving. The project...

The Drazin inverse solutions of the matrix equations AX = B, XA = B and AXB = D are considered in this paper. We use both the determinantal representations of the Drazin inverse obtained earlier by the author and in the paper. We get analogs of the Cramer rule for the Drazin inverse solutions of these matrix equations and using their for determinantal representations of solutions of some differ...

Some new estimates for the eigenvalue decay rate of the Lyapunov equation AX + XA = B with a low rank right-hand side B are derived. The new bounds show that the right-hand side B can greatly influence the eigenvalue decay rate of the solution. This suggests a new choice of the ADI-parameters for the iterative solution. The advantage of these new parameters is illustrated on second order damped...
