Ursula C. Schwerin at Commencement Ceremony

Ursula C. Schwerin (right) is pictured in graduation regalia at a commencement ceremony for the New York City Technical College. The date of the ceremony is unknown. Ursula C. Schwerin, a former City Tech student, was president of the College from 1978-1988. She was the first woman to be president of a community college in the CUNY system along with the first woman to be president of a technical college in the U.S. Under Schwerin's tenure, the College made the transition from a two-year to a four-year senior college. and the school was thus renamed New York City Technical College.

Otto Klitgord at 1952 Commencement

Otto Klitgord (second from left) is pictured with other guests at the Hotel St. George, site of the February 1952 commencement ceremony of the college. Otto Klitgord was the first president of the New York City College of Technology. He was named director of the New York State Institute of Applied Arts and Sciences when it was formed in the 1946 and became president in the 1950s when the administration was reorganized. Klitgord served until 1960, making his tenure as president the longest in City Tech's history.

Laser interferometric characterization of a vibrating speaker system

An experiment that combines opto-mechanical and electrical measurements for the characterization of a loudspeaker is presented. We describe a very simple laser vibrometer for evaluating the amplitude of the vibration (displacement) of the speaker cone. The setup is essentially a Michelson-type interferometer operated by an inexpensive semiconductor laser (diode laser). It is shown that the simultaneous measurements of three amplitudes (displacement, electrical current, and applied voltage), as functions of the frequency of vibration, allow us to characterize the speaker system. The experiment is easy to perform, and it demonstrates several useful concepts of optics, mechanics, and electricity, allowing, students to gain an intuitive physical insight into the relations between mathematical models and, an actual speaker system.

May Commencement

Few Nebraskans are as devoted to the University of Nebraska as Mark Gustafson. Driven by his belief that a strong university is key to a strong Nebraska economy, Mark is an advocate for the university in the local, state, and national arenas. He is a Nebraska delegate to the Council for Agricultural, Research, Extension, and Teaching, a national advocacy organization for higher education. Since 1991, he's been a member of Agriculture Builders of Nebraska, Inc., which supports UNL's Institute of Agriculture and Natural Resources, as well as the entire University, and has served three terms as president. He has served on the advisory councils for the UNL chancellor and the NU president and served on UNL's Future Nebraska Taskforce. He holds baccalaureate and master's degrees from UNL and a Ph.D. from the University of California-Berkeley.
