Real Engineering Projects

As someone who is nearing the completion of his final year project, I wanted to know what final year projects people are doing that involve real Engineering and Research, along with any results that you have gotten. Let's fester a culture for actual engineering here.

I'll go first- I'm working on a theoretical CS research project on "Incremental Topological Ordering on Directed Acyclic Graphs(DAGs) under Predictions". We have so far been able to record a 1000x improvement in certain scenarios over the state of the art algorithm.
