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.
