Grading Policy

Pop Quizzes (10%)Pop quizzes will be based on the assigned reading or material covered in class. A pop quiz might take place at any time during the lecture period and in addition to the above will also cover the material that is currently being presented.

Homework (20%)Assigned weekly and due at the beginning of the class period. Homework will be either analytical and/or computational. I reserve the right to inquire from you to demonstrate your computer work.

Semester Exam (40%)Two exams each worth 20% of your grade. These exams will be comprehensive and may consist of two parts (an analytical and a computational). Note that part or the whole exam may be take-home. In class exams will be closed book-notes. No makeup exams will be given unless I am notified in advance and approve of it. The time of the exams will be announced later.

Final Exam (30%)The final exam will be comprehensive and it may consist of two parts an analytical and a computational. The final exam will be closed book-notes. If you have any conflict with finals for your other courses you must inform me in writing no later than the third class meeting. Otherwise, I will assume that you will be able to take the final exam at the university's scheduled time.

Guaranteed Grading ScaleThe guaranteed grading scale based upon the minimum percentage number of points obtained is shown below. The required percentages will not be increased but they may be decreased based upon overall class averages at the end of the semester.

90% - 100%: A, 80% - 89%: B, 70% - 79%: C, 60% - 69%: D, 0 - 60%: F

SoftwareYou may use any computer software that you like, but make sure that you are proficient in it for solving the assignments for this class. The department provides Matlab, Excel, Mathcad, etc. in the PC lab. For the purposes of this class, support will be provided only for Matlab.

MiscellaneousIf you have any religious holidays that you need to observe you must inform me in writing of the dates no later than the third class meeting.

NotesSoftware will be used throughout the course. We will be introduced to a few software packages but we will primarily use Matlab. The use of software is encouraged in order to allow us to study more examples and better understand the concepts presented during the lecture period. Homework problems will be specifically assigned to be solved with computer tools. However, be careful not to be carried away and learn the software commands without paying attention to the physical nature and understanding of the exercise/

problem being analyzed.

The sciences do not try to explain, they hardly

even try to interpret, they mainly make models.

By a model is meant a mathematical construct which,

with the addition of certain verbal interpretations,

describes observed phenomena. The justification of

such a mathematical construct is solely and precisely

that is expected to work.
