Course Plan
Seminar: Each student shall identify a topic of current relevance in his/her
branch of engineering, get approval of faculty concerned, collect sufficient
literature on the topic, study it thoroughly, prepare own report and present in
the class.
Project preliminary: Identify suitable project relevant to the branch of study.
Form project team ( not exceeding four students). The students can do the
project individually also. Identify a project supervisor. Present the project
proposal before the assessment board (excluding the external expert) and get it
approved by the board. The preliminary work to be completed: (1) Literature
survey (2) Formulation of objectives (3) Formulation of
hypothesis/design/methodology (4) Formulation of work plan (5) Seeking funds
(6) Preparation of preliminary report Note: The same project should be
continued in the eighth semester by the same project team.
