R & D INITIATIVES AT NEELKANTH GROUP OF INSTITUTIONS

At NIET, we understand the need of taking initiatives to promote small projects based creational work , which may keep the polytechnic students with the paces of developments in Science & Technology. Therefore all the students are provided adequate field exposure and technical visits. Purpose of the small project based R & D is:

(i) To develop abilities of diagnosing problems.
(ii) To develop the abilities to make literature survey, to design/develop/fabricate/test simple circuits, to prepare documents and to work as a team.

Depending upon the complexity of the work, the teacher assigns project work to a group. The group size is decided by the teacher, normally between 2 to 4 students per group. It is compulsory for all of the students to work on live projects which cover the following key areas (including writing of Technical Report):

We set out to involve students, parents and staff as active partners in the learning process, in a relevant, engaging and challenging educational programme, through commitment, self reflection and continuous improvement. We therefore firmly believe-

COMPUTER SCIENCE & INFORMATION TECHNOLOGY

COMPUTER SCIENCE PROJECTS (SW/HW):
The student is expected to work on a project in consultation and acceptance with the instructor on either system software or hardware aspects related to industrial environment. The student is also expected to fabricate different cards used in PC, their testing and assembly of PC. The end targets for the project should be well defined and evaluation should place major importance on meeting these targets.

DATA PROCESSING PROJECTS:
The student is expected to work and learn from implementing an application software and study its functional and performance aspects and submit a report. The evaluation must be based on the project report and the seminars.
