This volume presents a selection of expository papers on various topics in engineering mathematics. The papers concern model problems relating to, amongst others, the automobile and shipping industries, transportation networks and wave propagation. Among the methods treated are numerical methods, such as the finite element method and Newton's method, Karmarkar's interior point method and generalizations, and recurrence and induction in computer science. This volume will be of great interest to applied mathematicians, physicists and engineers interested in recent developments in engineering mathematics. The papers are written with an emphasis on exposition and should be accessible to all members of scientific community interested in modeling and solving real-life problems.
