Story Ideas from the School of
Engineering
Picture This
A propensity for seasickness hasn't kept Joseph Katz from
exploring the ocean's depths. A professor of mechanical
engineering, who has spent much of his career analyzing the
hydrodynamics of submarines and the flow structure within pumps,
Dr. Katz is now bringing his unique holographic devices to the
field of oceanography. He has developed a Submersible Holographic
System, which uses sophisticated underwater cameras to study
never-before-photographed microorganisms and ocean particles. The
system, which has been tested in Baltimore's Inner Harbor, should
be operational and ready to be submerged in the Atlantic Ocean in
the next few months.
Out of This World
Some research scientists toil for a lifetime without seeing the
fruits of their labors in the "real world." For 30-year-old
Oliver Collins, an assistant professor of electrical and computer
engineering, his rewards have been almost immediate. Twice, his
coding innovations have been used to solve mission-threatening
information transmission problems on NASA's deep-space probe,
Galileo. In recent months, Collins has received the Browder J.
Thompson Memorial Prize for his paper on decoder design, and the
Marconi Young Scientist Award. Currently, he is continuing his
coding research in the areas of terrestrial satellite and
cellular telephone communications.
Gently Finding Faults
Bob Green is a problem solver. For 10 years, he and the
researchers who work with him at his Center for Nondestructive
Evaluation have found non-invasive methods for determining the
reliability of products without damaging them. Lasers, X-rays,
ultrasound and holograms are among the tools that help CNDE
scientists test just about anything--heart valves, jet engines,
refinery walls, even the silk in First Ladies' inaugural
gowns--for invisible flaws, leaks and weaknesses. Industrial and
corporate sponsors fund the work in return for timely access to
research findings and the graduate students who are trained at
the center.
