CHE/ME 109  Heat Transfer in Electronics

Fall 2004

The good student strives not for easy answers, but for genuine understanding, persevering in the face of obstacles.  The good student wishes not just to "get it done," but to "get it right"; not simply to "get ahead," but to "get the most out of it."

                                                                   The Portsmouth Declaration,  Link Institute  

Prerequisites:  Math 133A, Phys 52, and EE 98

All students are required to turn in a signed prerequisite verification form distributed the first day of class.  All three prerequisite courses must be completed before enrolling in this class.  There are no exceptions to this.

Instructor:             Dr. Claire F. Komives                   Class Hours  Section 01: MW 1600 - 1715

Office Hours:         MWF:  9:30 a.m.-11:30 a.m.       Classroom:   BBC 004

Text:             Heat Transfer:  A Practical Approach, Second edition 2003 or Primis Book, Y. A. Cengel, WCB McGraw-Hill

Students are required to acquire the text.  Sharing texts on exams and quizzes will not be permitted. 

Examinations:  There will be two examinations during the semester and a final exam.  All exams will be open textbook with one note sheet.  No make-up or re-scheduled exams will be given.  Short unannounced quizzes may also be given during the semester.

Homework:  Homework will be collected at the start of class each Wednesday.  The entire assignment may not be graded, but a randomly chosen portion of the homework will be graded.  The homework assignments can be downloaded from the instructors website (homework), but homework and exam solutions will not be posted on the website.

Homework hints may be provided in class.  If these are provided for a given assignment, the minimum credit for homework turned in on time will be 50% credit if all the problems are solved to the desired value stated in the problem, even if the final answers are incorrect.  If no homework hints are provided, the minimum credit for homework turned in on time will be 70% credit if all the problems are solved to the desired value stated in the problem, even if the final answers are incorrect.  Solving the homework problems is essential to your successfully mastering the material in this course.  Students who turn in all their homework are more likely to do well on the examinations than those who do not attempt the homework.

Course Grade:  The final grade for the course will be determined as the cumulative weighted average of all assigned work.  The weighting for each of the categories of work is as follows:

            Homework:                           10%

            Quizzes:                                 5%

            In-class problems:               5%

            Reading Assignments:         5%

            Midterm Exams:                  50%          

            Final Exam:                           30%

Time Commitment:  It is expected that each student will devote a minimum of 4 - 6 hours per week studying the assigned reading and doing the homework.

Exam Content and Grading:  You can expect the problems on the exams to cover concepts from the lectures and homework, however, they will be different from the problems assigned in homework or class group problems.  Engineering is the application of technical knowledge, and you need to demonstrate your ability to apply the science of heat transfer to practical problems.  Grading of the examinations will be based on the assumption that the student completed all the assigned homework and clearly understood all the required basic assumptions and equations used in the homework and that the student attended all the lecture classes.  As stated above, exams will be open textbook and closed notebook with the use of one sheet of notes prepared by the student.

Cheating and Plagiarism will not be tolerated in this course.  Cases of academic dishonesty will result in an F on the exam or assignment and administrative disciplinary sanctions, and may result in an F in the course.  Please review the College of Engineering Academic Honesty Code found in the Spring Course Schedule.   Definitions of cheating are also presented and hold for this course.

Course Structure:  The principles of heat transfer applied to electronics will be developed by lecture and reading outside the class. Applications will also be discussed in lectures and developed with homework and in-class projects.

On the first day of class, students will be asked to fill out a questionnaire about learning preferences. 

Prior to the second class meeting, the students should fill out The Index of Learning Styles Questionnaire that can be found at http://www.engr.ncsu.edu/learningstyles/ilsweb.html. 

After taking the questionnaire, please submit for the results.  Read the four numberlines and record your numbers:

   

PLEASE e-mail the results (as described in the box to the right) to Dr. Claire Komives

Based on these results and the questionnaire from the first day of class, the instructor will make student teams of 3 people each.  Students will be asked to sit with the teams for the duration of the semester in order to work together on class group projects.

STUDENTS WHO HAVE NOT COMPLETED THIS SURVEY AND THE PREREQUISITE CHECK LIST PRIOR TO THE SECOND WEEK OF CLASS WILL BE INSTRUCTOR DROPPED.

Students will prepare for each lecture by reading through the appropriate text material as described in the syllabus below listed in the text reference column, including the example problems contained in the text. Students should complete the reading assignment that can be downloaded from the course website.  The goal of the reading assignments is to assist students in extracting the important concepts from the assigned reading.  Quiz problems will be closed book/closed notebook and will be based on material covered in the lecture and in the text, especially on the example problems from the assigned reading.  There will be some problems to be solved in class in groups, to develop concepts and also applications.
