5. Major Project The final project is where a student applies the knowledge gained over the course of their studies to deliver a well researched, technically strong body of work. Important stages in this activity will include: • Project selection • Interim presentation • Submit unbound copy for proof reading • Submission of final bound thesis Dates as per handout N.B. It is essential that all projects contain a strong analytical / technical element.

6. Project selection • Projects may come from one of the following: • List of projects presented by staff. • Ideas drawn from your own experience/interests. • Industrially based project. • Selection process. • Project list posted on web page • Meet with staff to discuss project ideas • Submit Project preference (Monday 19th Sept) • Project / supervisor allocation (Wed 21th Sept) • Project guidelines and project proposal form to be forwarded later this week. • In the meantime give some thought to project ideas of your own.
