The seminar power point presentation shall be fundamentals oriented and

advanced topics in the appropriate branch of engineering with references of

minimum seven latest international journal papers having high impact factor.

Each presentation is to be planned for duration of 25 minutes including a

question answer session of five to ten minutes.

The student’s internal marks for seminar will be out of 50. The marks will be

awarded based on the presentation of the seminar by the students before an

evaluation committee consists of aminimum of 4 faculty members.

Apportioning of the marks towards various aspects of seminar (extentof

literature survey, presentation skill, communication skill, etc.) may be

decided by the seminar evaluation committee.

A bona fide report on seminar shall be submitted at the end of the semester.

This report shall include, in addition to the presentation materials, all

relevant supplementary materials along with detailed answers to all the

questions asked/clarifications sought during presentation. All references

must be given toward the end of the report. The seminar report should
