Lectures: Tuesdays, Thursdays: 11:00-12:30 AM,
West Mall Swing Space (SWNG), Room 121.
Class Notes: The students should print their class notes and bring them to each class.
Office Hours: Fridays - 2:00-4:00 PM
For other times, send email to arrange a meeting (always include “EECE373” in the subject line)
5 Lab Experiments (will be determined during the course)
Laboratory experiments are an integral part of this course. In order to pass this course, all students are required to attend (attendance will be recorded), comply with the Laboratory Rules, perform adequately, and write reports for all experiments.
Lab Reports are due one week after the completion of experiment. Late submission will result in reduced marks (10%/day up to 3 days, and zero mark thereafter).
We have three Lab Sections: “^” (Alternate week, starts Sep. 17)
L1A – Tue. 8:00 – 11:00 AM
L1B – Tue. 13:00 – 16:00 PM
L1D – Thu. 16:00 – 19:00 PM
Lab-0: Lab Safety Rules Sep. 18, 20
Lab-1: AC/DC Circuits and Measurements Oct. 2, 4
Lab-2: AC Transformers Oct. 16, 18
Lab-3: Brushed DC Machines Oct. 30, Nov. 1
Lab-4: Induction Motors & VFDs Nov. 13, 15
Lab-5: Synchronous Machines Nov. 27, 29
The reports for the last Lab-5 are due on Dec. 4 and Dec. 6, respectively. You can also submit your reports earlier directly to one of the TAs. You must submit the reports for all 5 labs in order to be permitted to write the Final Exam.
Exams: There will be one Midterm Exam (in class, on Oct. 25)
Missed exams cannot be made up. In the case of illness (with advanced notice
and doctor’s note), the weight of Midterm Exam may be added to the
Quizzes: There will be several, 5 to 6, short (10-20 min.) quizzes given in the beginning of some lectures. The quizzes will be collected and marked. Missed quizzes cannot be made up and will result in zero mark. In case of illness or other legitimate reason (with advanced notice and doctor’s note), the weight of missed quiz may be added to the Final Exam.
Next Quiz: Thursday Nov. 29.
Assignments: There will be about 6 assignments throughout the course. Assignments will normally be collected at the specified due date. The assignments will be collected and counted, but will not be marked. The solutions will be posted on the web after the due date. The assignments may be looked at in the end of the term only if the student’s grate is on the pass/fail borderline.
Submission Policy: Assignments and Lab Reports will normally be collected at the specified due date at 4:00PM from the Drop-in Box labeled EECE373 Lab Reports on the first floor in MCLD building, close to the room 112B. All late Reports and Assignments must be given directly to the TA who will record time and date of submission. Late submission of Lab Reports will result in reduced marks (10%/day up to 3 days, and zero mark thereafter). Late submission of Assignments will not be accepted after the solutions have been posted on the web.
Grades: The final grade will be based on the following:
Assignments – 5%
Quizzes – 20%
Lab Reports – 15%
Midterm Exam – 20%
Final Exam – 40%
Each student must pass the Final Exam (get 50% or more) in order to pass this course. If the mark for the Final Exam is less then 50%, then this failing mark becomes the mark for the whole course.
Cheating Policy: Students are encouraged to discuss among themselves the problems in each assignment and lab experiment. However, the turned-in assignments and lab reports must show the individual work and reflect the individual understanding of material by each student. Reports suspected of cheating will not be graded (zero mark). Cheating on exams will result in zero mark and may qualify for withdrawal form the course and/or suspension from the University. Please see the UBC Regulation on Cheating and Plagiarism. All instances of cheating will be reported accordingly to this policy.
Teaching Assistants (TAs): We will have three TAs for this course:
Hamid Atighechi, Email: hamida at ece.ubc.ca
Mehrdad Chapariha, Email: mehrdadc at ece.ubc.ca
Milad Fekri, Email: miladf at ece.ubc.ca
Their offices are in the Power Lab in Kaiser 3085.
For questions regarding assignments/quizzes and marks, please contact TAs via their email and set up an appointment (always include “EECE373” in the subject line).
