Preliminaries

What should you gain out of your B.Sc. Project?1. Learn the METHODOLOGY of doing a project

Plan a work schedule & achieve it Being original Defy obstacles on your own Document your work Work in a team

2. Apply the information you study from different courses in one common project.

3. What kind of ENGINEER are you really going to turn out to be?


Preliminaries

What types of B.Sc. Projects are out there?

Study & Design Practical &ProductionResearch


Preliminaries



Research: Contribute to the advancement of technology. It is challenging & satisfying to be the first to do

something Aiming for a masters degree?


Preliminaries



Study & Design: Master the understanding of material you study in

different courses Develop, design and implement a simulation model


Preliminaries



Practical & Production: Have an output product/Hardware (not just curves

from a MATLAB model) A type of activity you would do possibly in work when

you graduate
