Students must satisfy each evaluation component in the course to receive a final grade. • It is the responsibility of each student to contact the instructor in a timely manner if he or she is uncertain about his or her standing in the course and about his or her potential for receiving a failing grade. Students should also familiarize themselves with Sections 4 and 6 of the Regulations dealing with incomplete term work, deferred examinations, attendance and withdrawal. • No programmable devices or systems, such as calculators, PDAs, iPods, iPads, cell phones, wireless communication or data storage devices, are allowed in term test/examinations unless approved by the course instructor. Academic Integrity Students are expected to conduct themselves in accordance with the highest ethical standards of the Profession of Engineering and demonstrate academic integrity in all their pursuits and activities at the university. As such, in accordance with the General Academic Regulations and Requirements of the University of Manitoba, Section 7.1, students are reminded that plagiarism or any other form of cheating in examinations, assignments, laboratory reports or term tests is subject to serious academic penalty (e.g. suspension or expulsion from the faculty or university). A student found guilty of contributing to cheating in examinations or term assignments is also subject to serious academic penalty.

What is expected of me? 1. It is better to be prompt and have good attendance since the lecture in class is important. Class note only provides general information covered in the class, not all the details. 2. Homework is due one week after it is assigned. 3. Pass two term and final exams. Please note that
All exams will be closed book. Only a double-sided (8.5x11in) hand-written formula sheet will be allowed in exams. No make-up exams will be given unless documented excuses are submitted and approved by the instructor. Late submission for homework will not be accepted unless documented excuses are submitted. All submissions must be in hard copy.
Assignments: Reading: You are suggested to read the assigned topics before the class in which they will be discussed. This will make the lecture more understandable and will enable you to be prepared to ask questions. Written: Homework problems from the textbook will be assigned.
