[email protected]. Prerequisite: MTH140 (Calculus-I) and MTH141 (Linear Algebra) COURSE ORGANIZATION: The course has 3-hrs lecture per week. There are five labs on schedules noted in this course management sheet. The labs are either in ENG 301 or ENG 302. Tutorial sessions may be posted on YouTube. Additional tutorial sessions would be announced prior to midterm and final exams if a place is available. These sessions are not mandatory and will be announced in-class. EVALUATION: 0% Homework3 25 % Laboratory 4, 5 Mid-Term Test6, 7, 8, 9, 30 % Final Exam9, 10 45 % -------------------------------Total 100 % Note #3: Homework questions are posted on Blackboard. Solutions for the book of Sadiku are already posted. Although homework has no value, at least two questions from homework will be included in the midterm and final exams with values changed. Note #4: Students must achieve passing marks in both theory and lab components separately in order to receive a passing grade in this course.
2 Each lab has a pre-lab and a post-lab, they are meant for practice. There are five labs. A group of two students are supposed to work together to learn how to do the lab components. Lab 1 does not have pre-lab. Labs 2 to 5 have some pre-lab calculations as well. The pre-labs include watching the YouTube components of the labs In order to successfully finish the labs, students are strongly urged to see the YouTube for labs before the labs actually begin. The YouTube covers all the important aspects of the labs giving a strong support. The labs mark breakdowns are as follows. Each lab attendance and readiness is marked as 2% (i.e., a total of 10%). A student who is absent from the lab for 10 minutes (at the beginning, in the middle, or at the end) will lose the attendance share. A student coming late to the lab is allowed to participate but will not receive mark for the lab missed. There is no makeup for the labs. The TA may ask to see the measurements, so please show the measurements to the TA before disconnecting the lab circuit. Students complete pre-lab report, implementation, and post-lab report in the session and will leave the lab. Students may consult the TAs for the pre- and post-lab questions if they have any. There are lab tests that are conducted individually. There are two lab tests worth a total of 15%. The first lab test is conducted after labs 1 to 3 are completed. It is worth 8%. The second lab test is conducted after labs 4 and 5 are completed. It is worth 7%. Lab tests are scheduled for one hour per person and have small pre-lab, implementation, and post-lab reports handed in. These test reports are written per person, will be marked and posted online. There is “no question asked” policy for lab tests. Students must use actual lab sessions as their practice run, as there is no practice lab prior to tests. Note #5: A student missing two labs, or missing two lab tests, for any reason, will have to report to their program director or consular for proper planning. Note #6: The midterm is scheduled on Wednesday Oct. 22th, at 3pm in the regular classroom. Anything covered up to Oct. 15th will be in this midterm exam. This exam is a two hours and 30 minutes exam. It has 8 questions. Two questions will be selected from the homework assigned randomly with values changed. Note #7: Students missing the midterm for medical reasons can make up the test on Nov. 28th, at 6pm. Note #8: A remark of midterm papers, if requested, would be done in the last week of classes, i.e., Nov. 24th to 28th. There is no makeup session for missed lab sessions. Anybody who misses a lab session should make every effort to make it up in any given extra sessions provided a seat is available. Note #9: The Midterm, makeup test, and the Final Exam are “closed book” and “closed course note” exams. No formula sheet is allowed. Only university-approved calculators are allowed. Also, both midterm and final exams are “no-question-asked” exams. Only the non-programmable approved calculator (Sharp EL546 or Casio fx-991MS and their later models) will be allowed. Please see blackboard and Youtube on how to use them. Note #10: The last teaching session is on Wednesday, Nov. 26th. The Official final exam will be announced by the timetabling dept. Final exam includes materials discussed from beginning to the end. Note #11: Important Dates: Friday, Oct. 3rd: Final date to drop a Fall undergraduate class for full- time Undergraduate program students to be eligible for a 50% refund (if a class drop results in a lower fee range).
3 Monday Oct. 13th: Thanksgiving day. No classes. Monday Oct. 13th to Friday Oct. 17th: Study Week. Teaching sessions in Engineering will continue. Sunday, Nov. 2nd: Daylight Saving Time ends. Friday, Nov. 14: Final date for full undergraduate students to drop Fall 2014 courses in good academic standing (no refund of Fall 2014 fees).

LAB: A fresh hardcopy of the lab manuals per lab session will be provided when group attends the session. Students must pass both the lab and theory parts separately to pass the course.
4 Lab Regulations 1) Students attend the lab in a group of two, unless otherwise noted by the TA. 2) Students must prepare for each lab. Read the Introduction in the Laboratory Manual. To optimize the time in the lab, students are strongly urged to watch the YouTube Videos related to the labs before they come in for the lab. Anyone coming to lab late by 10 minutes will be marked as absent. There is no make-up lab. A Lab exemption will be made only on valid medical report. 3) A grade zero is assigned to a student who is absent for 10 minutes during the lab, or do not complete the lab components. Being absent from two lab tests is equivalent to failing the course, with the exception of extreme medical case. 4) Each student in the group needs to bring with her/him the pre-lab. Students need not to hand in pre-lab materials. 5) Each student in the group will be asked to show at least one implementation (measurement) to the TA. A grade zero for implementation will be assigned to a student who is not able to show the measurement in the lab in the presence of the TA. 6) The TA has the right to ask questions in regards to pre-labs, implementation, or post-lab questions, or to modify the lab assigned to evaluate students on the implementation part. 7) Remember that your TA should sign your lab implementation page, before you leave the lab. 8) There is one post-lab per group. Students do NOT have to hand in pre- and post-lab reports. Each student would be tested by lab tests and students are strongly encouraged to take the labs seriously while it is running in normal sessions. Failing the lab tests is equivalent to failing the course. LAB TESTS: One hour lab test (implementation + written test) will be held per schedule noted below. Students will be informed of the order in which the students will enter the lab room for the test. Out of the three labs (labs 1 to 3), in the first lab test, and out of the last two labs (labs 4 and 5), a lab test is designed which includes pre-lab (approximately 15 minutes) and requires implementation and measurements (approximately 45 minutes). The TA should see and sign the measurements sheet. The mark distributions of a lab test are shown on the lab test sheet.

The accommodation of those who are not registered in a specific lab session depends on the availability of the lab desks.
