Course out-comings (complying with ABET A-K): After this course, you (the student) should have
    A. An ability to apply knowledge of mathematics, science, and engineering.
    B. An ability to design and conduct experiments, as well as to analyze and interpret data.
    G. An ability to communicate effectively.
    K. An ability to use the techniques, skills, and modern engineering tools necessary for engineering practice.

Grade Policy: The final course grade will be determined approximately as follows:

  • Homework: 20%
  • Quizzes and tests: 40%
  • Project or final: 40%

The instructor reserves the right to give extra credit to active participation and demonstrated interest and capability. Grading scale observes: A=(92,100], A-=[90, 92], B+=(87, 90), B=[83, 87], B-=[80, 83), C+=(77, 80), C=[73, 77], C-=[70, 73), D+=(67, 70), D=[63, 67], D-=[60, 63), F=[0, 60). [ or ] means inclusive, ( or ) means exclusive.

Homework: Homework will be assigned on Wednesday and due the following Wednesday. Some assignment will involve development of computer programs.
