January 30, 1997 Prof. Chryssostomos Chryssostomidis MIT Department of Ocean Engineering Rm. 5-226 77 Massachusetts Ave. Cambridge, MA 02139 (617) 253-4330 Dear Prof. Chryssostomidis, I am writing to ask for an extension to my time as a Graduate Student in the Department of Ocean Engineering. My studies were prolonged as a result of a combination of factors, most notably a change in advisors and a change in the thrust of my thesis. These changes are now behind me and I am pleased to report that as of my last thesis committee meeting on January 6th the committee was pleased with the progress of my research and has asked me to establish the metrics by which my efforts can be judged and compared. To this end I am now working on the definition of these metrics and plan to complete the task by the 31st of January. If the committee finds these results satisfactory, I plan to complete my thesis and defend it on or before the 23rd of May, 1997. I am therefore asking for an extension of my time here at MIT through the end of the Spring 1997 semester. A detailed timetable follows: Jan 30th Complete new research (metric definition) Jan 31st Present to Committee March 28th 1st Draft of thesis complete April 10th Mock defense May 9 Thesis defense May 23 Hand in completed thesis Sincerely, Andrew Bennett
