TEACHING STRATEGIES
Class Lectures:
Each class will start with a 5-10 minute review of the previous class. Then we cover new
material and close with an overview. I typically ask a lot of questions during class to make sure
you understand the material and wait until somebody answers. I encourage you to try to
answer the questions.

UNIVERSITY POLICIES
The University is an equal opportunity educational institution. Please read The University’s Policy
Statement on Nondiscrimination on the Basis of Disability Americans with Disability Act Compliance.)
Academic Accommodations
The University of Toledo is committed to providing equal access to education for all students. If you have
a documented disability or you believe you have a disability and would like information regarding
academic accommodations/adjustments in this course please contact the Student Disability Services
Office.)
ACADEMIC POLICIES
There will 2 midterm and a final exams. There will about eleven homework assignments. You must
submit homework assignments in class on the due date. No late homework will be accepted.
Your grade will be based on the following: Homework (20%), Midterm exams (25% each), Final (30%)
Missed homework or exams: If you are unable to submit a homework or take the final exam because of a
genuine emergency (such as illness, jury duty and funeral) then you should contact me by E-mail or in
person and provide written documentation as soon as possible. Submit your assignment as soon as
possible. In case you have to miss the final exam I will decide if I will give you a make-up exam or adjust
the weight of the final exam or other homework assignments. If you fail to provide proper written
documentation of the emergency you will get a zero for the assignments, or exams you missed. Note
that going on vacation is not considered an emergency.
COURSE EXPECTATIONS
Students are expected to attend classes, watch lectures and submit assignments on time. No late
assignments are accepted.
GRADING
Your grade will be based on the following: Homework (20%), Midterm exams (25% each), Final (30%)
Missed homework or exams: If you are unable to submit a homework or take the final exam because of a

that going on vacation is not considered an emergency.
The grade will be determined based on the following scale:
Overall score Letter grade
90-100 A or A80-89.99
B or B+ or B70-79.99
C or C+ or C3

Introduction: goals, terminology

Gears
The professor will post the solutions of a homework or design project on the course web page
after the submission deadline. Assignments submitted after the solutions have been posted will
receive a zero grade.
In order to pass the class, students must submit all assignments and quizzes before the deadline
posted.
Computer usage: Some homework problems can be solved efficiently using computer. You can
use any software program you like including Excel, MathCad or Matlab.
Academic dishonesty: Students may discuss and exchange ideas about homework assignments
and projects but they are expected to submit their own work. No collaboration is permitted in
exams. Trying to get credit for someone else’s work or deprive another student from getting
credit for his/her own work will be considered academic dishonesty. If a student observes such
an incident, the student must report it to the professor. The incident will be investigated.
Penalties include, but are not limited to, getting an F for an assignment or an exam, getting an F
for the class or dismissal from the College of Engineering or the university.
Cellular phone policy in class: Use of cellular phones during class distracts students. Therefore,
cell phones must be switched-off during class.
Class attendance: You are expected to attend all class sessions. If you have a genuine
emergency that prevents you from attending a class, you should contact me by Email preferably
before the class. You will still be responsible for getting the information you missed.
