ECE3183 Section 02 Fall 2007

From Ece

IMPORTANT NOTE: The outline for the final exam is below.
The final exam is Friday, Dec. 7th 3-6 PM

There is an opportunity for anyone who wants bonus points to give a short presentation (8-10 minutes) on an electrical subject of their choosing. Since this is a survey class for other engineering disciplines, a good topic idea would be how EE is used in your field. ChemE's could talk about electrophoresis, ME's could talk about robotics, IE's could talk about electronic component production processes, ASE's could talk about avionics, etc.

The specs:

A maximum of 20 points will be added to test # 3 (That's a max of 5 points added to your final grade!!)
8-10 minutes long, well-presented (Educate us on the topic). The time can include **meaningful** discussion, so prep your friends on your topic and get them to ask real questions.
Sufficient technical content - don't just paraphrase a HowStuffWorks article. Give us at least a few basic formulas or other quantifiable info.
Format is open - you can use Powerpoint, but you don't have to. A plain old lecture on the board is fine.

Homework

Homework problems will be assigned, but not collected or graded. They are assigned simply to provide preparation for the tests.

Attendance

Students are expected to be present for all tests and for the final exam. In extreme cases, I may arrange a make-up test. I will not be taking regular attendance, but I strongly suggest coming to class as the tests are based off of material discussed in class.

Academic Dishonesty

Students are expected to adhere to the MSU honor code

As a Mississippi State University student I will conduct myself with honor
and integrity at all times. I will not lie, cheat, or steal, nor will I
accept the actions of those who do.
