To learn to review and assess technical literature critically. To write and present an overview of the relevant literature for a specific technical / research topic.

The seminar topic may be

Mechanical Engineering Based on Interdisciplinary subjects. Recent trends in Engineering field.

The topic should be based on recent research paper published in International Conference / Reviewed Engineering Journals of International Repute in print media.

Each student should have a different seminar topic and its presentation. In case more than one student is working on the same topic, then their scope of seminar must be distinct.
