Multidisciplinary Applications of Spectral Analysis at the University of
At the University of Alabama (UA), Sally McInerny, associate
professor of aerospace engineering and mechanics, and electrical engineering associate
professors Harold Stern and Tim Haskew have developed a junior-level multidisciplinary
laboratory course centered around industrial applications of dynamic data acquisition
and analysis. "By using a team of professors to teach the course," says
Stern, "we could show the students how professors work in teams. And by using
professors from different disciplines, we could help the students see concepts
from different perspectives and how different disciplines share common principles."
The instructors designed the course to integrate topics in digital signal processing,
communications, acoustics, vibrations, electric machines, and power. Multidisciplinary
teams of aerospace, electrical, industrial, and mechanical engineering students
develop a qualitative understanding of time and frequency domains. "Interdisciplinary
interaction in upper-level lecture courses is helpful to students," says
McInerny, "because it allows them to see some of the common principles and
themes that run through all disciplines of engineering." Instructors use
resources available via the Web and movies developed with MATLAB to help students
develop a foundation for later work. With a conceptual foundation in place, students
work to understand the breadth of possible applications, studying four laboratory
modules: speech encoding and enhancement, machinery sound power measurement, machine
condition monitoring, and motor condition monitoring. The course ends with a small
