Program tanımları
Graduate programs leading to the Master of Science degrees in Earthquake Engineering, Geodesy, and Geophysics normally involve two years of graduate work and include,
a) A minimum number of 24 credits of course work to be completed in two successive semesters,
b) A thesis to be completed in the following two semesters.
Of the minimum number of 24 credits, at least one-third should be comprised of required courses specified by the program in which the student is registered. The remaining two-third may be chosen from among elective courses of the program or the courses acceptable by regulations of the Institute, subject to the approval of student advisor. The 24 credits of course work is normally made up of 500 and 600 level courses; however, with the approval of the advisor, some of the program may be composed of 400 level courses, a maximum of two of which with credit, not taken in the students undergraduate program.
Upon completion of course work with a grade-point average of at least 3.00, the student is required to carry out supervised research and complete a thesis in at most two successive semesters. At the discretion of the Institute, this period may be extended by one semester. The student is required to pass an oral examination after the thesis is submitted for approval.
Students with backgrounds in Geodesy and in Geophysics, in Geology and particularly in Physics, in Mathematics and in Computer Engineering may apply to M.Sc. program. However, students without a background in Geodesy and in Geophysics may be allowed to extend their course work to three semesters, taking complementary courses in related fields with the approval of advisor.
