EEE 500: ENGINEERING PROJECT II
Each student will be required to undertake a simple practical project involving specification, review, analysis, design, development and research. The student is presented with a real world engineering problem, and the solution to the problem must demonstrate a rigorous scientific approach, i.e. problem definition, analysis, design, construction, measurement, evaluation and communication. Students are expected to work largely on their own initiative. The duration of each project is two semesters in the fifth year of study.
