The Abstract provides the reader with a summary of the contents of the dissertation. It should therefore be brief but contain sufficient detail, telling the reader the motivation for the work; project objectives; techniques employed; main results and conclusions. Abstracts should not normally exceed a page and should be self-contained.

The Abstract is the "gateway" to the contents of the dissertation, and therefore it is important that the Abstract gives the reader a good initial impression. Try to write Asbstract with a "punchy" style.
