EngMath Update

The EngMath Update (EMU) is an annual publication of the Department of Engineering Mathematics of the University of Peradeniya. The first issue of the EngMath Update was published by the department in April 1998. The primary goals of EMU are sharing information on the current research activities of the Department with the academic community, providing students and others information concerning the educational programmes of the Department, and serving as an introduction to the personnel and the goals of the Department. Copies of EMU 1999 are available at the libraries of the University of Peradeniya. Most of the information contained in EMU is also obtainable through the web pages of the Department of Engineering Mathematics.
