IPE 3112: Capstone Project 2.00 Contact Hour 1.00 Credit Hour
In this course students are required to undertake a design of a small electro-mechanical or instrumentation system. Use of locally available prospects materials will be emphasized. The capstone courses require students to draw upon all previous coursework and cultivate new skills in order to solve complex design problems associated with an assigned group project. The system design would involve the stages of concept building, engineering calculations, fabrication, presentation and demonstration of product. Emphasis is to be given in project management for solving Engineering problems to meet the socio-economic development. Lectures will be provided in the technical and project management aspects of the individual project selected.
