Materials: electronic material for every lecture will be provided. In some cases, Xerox of Dr. Lvov¡¯s transparencies and of journal papers corresponding to every lecture will also be provided. Reading of papers given at the end of each topic is not necessary but desirable (these papers will be provided). Four lectures are published on web: //www.latech.edu/~ylvov
Grading System: We will have two exams and four homework assignments. Four working groups and independent research projects on one of the given below topics will be organized. You are free to choose ¨C to join a group or to have an individual project. Every group has to elaborate a project, to perform an experimental work on the project, and to present 20-min oral report in class (10 transparencies prepared in electronic form are obligatory for every group). An input of every student to the teamwork has to be shown clearly. Individual projects on any of the below topics are welcomed. Grades will be given based on results of exams and a project, which will be reported in class and discussed (two exams 60%, home work 20% and report 20 % of the final grade, A 90-100%, B 80-89%, C 70-79%, D 60-69%, F <60%). An activity in class will be taken into account as well.
Attendance is strongly encouraged and will be checked at each class.
Students needing testing or classroom accommodations based on a disability are encouraged to discuss those needs with me as soon as possible.
In accordance with the American Honor Code, students pledge the following: being a student of higher standards, I pledge to embody the principles of academic integrity.
