Homework

Homework will be assigned every week and will be due by 12 pm (noon) on Wednesdays. Homework should be turned in in class or to the TAs by the deadline. No late homework will be accepted. I encourage you to discuss the homework among yourselves, but what you write and hand in should be your own work.

Work single-sided on new clean paper, stapled together. Print name, date, course and homework number on the first page; box final answers, especially for problems with multiple parts. Illegible homework will be returned ungraded.

Here is a suggested standard format (sample solution).

Problem Description. Basic description and given information. Sketch of problem/geometry and system considered (dashed lines for system). Intial state (knowns and unknowns). Final state (knowns and unknowns). Appropriate property diagrams (state points, process lines). What is to be determined.
Engineering Model. List all required simplifying assumptions and idealizations.
Basic Equations. General form of all relevant fundamental laws, equations, definitions.
Analysis. Clear description of procedure to reduce basic equations to solution. Keep equations in variable forms as long as possible before using numbers. Identify all tables and charts needed for additional data and property values. Clearly indicate final answers with box. Check solution: correct sign, reasonable numerical values?
Discussion of Solution. As needed (what you learned, key aspects of solution, etc...)

I do not insist on the entire format's being used: in particular sketching the problem and writing down given information will not lead to points. However you should use an equally clear format.

Grades will be determined by your understanding of the problem, identification of the procedure to obtain the solution, clear and precise description of the solution, and correct numerical answers.

I Due Oct 3. Solutions. Mean: 25.90/32. Standard deviation: 5.04.
II Due Oct 10. Solutions. Mean: 47.35/58. Standard deviation: 9.85.
III Due Oct 17. Solutions. Mean: 35.91/53. Standard deviation: 13.87.
IV Due Oct 31. Solutions. Mean: 44.63/64. Standard deviation: 14.18.
V Due Nov 7. Solutions. Mean: 40.91/58. Standard deviation: 10.80.
VI Due Nov 14. Solutions. Mean: 47.98/76. Standard deviation: 18.99.
VII Due Nov 21. Solutions. Mean: 34.37/45. Standard deviation: 9.84.
VIII Due Nov 28. Solutions. Mean: 31.00/43. Standard deviation: 10.87.
IX Due Dec 5. Solutions. Mean: 47.74/61. Standard deviation: 17.53.

Requests for regrades must be submitted in writing to me within a week of getting the homework back, with a justifcation for the regrade. Include name, date, e-mail address.

Quizzes

There will be five 50-minute quizzes in the fourth hour every other Wednesday starting October 10. There will be no make-up exams. All exams are closed book. Bring pencil and calculator to all exams.

I(a,b,c) Solutions. Mean: 10.38/20. Standard deviation: 3.81.
II Solutions. Mean: 12.75/20. Standard deviation: 4.51.
III Solutions. Mean: 13.06/20. Standard deviation: 4.93.
IV Solutions. Mean: 8.82/20. Standard deviation: 5.02.

Final

The final will be on Wednesday December 12 from 8-11 am. A make-up exam will only be provided for medical reasons with proper documentation from a physician. The final will cover the material lectured during the course and the material assigned as reading. Solutions. Mean: 51.79/120. Standard deviation: 17.53.

Pick up in EBUII 573 with ID after December 17.

Grading

Method A: Curve based on: Homework 10%, 3 best of 4 exams 40%, final 50%.
Method B: Absolute scale based on final: A > 80%, B> 70%, C>55%, D>40%.
Your grade will be computed by methods A and B and you will receive the higher of the two. I may rescale the different components (homework, quizzes, final) separately to arrive at the final grade. I do not recommend planning on Method B from the beginning. Method A is more reliable.

Cheating

I remind you of UCSD's policy on academic dishonesty. Action will be taken in cases of cheating. Don't make it happen to you.
