Listening to the Ocean
Kathleen Wage, associate professor of electrical and computer engineering at the Volgenau School of Engineering, studies sounds in the ocean and loves to spend time on research ships. Wage studied engineering at the University of Tennessee-Knoxville. As a UTK student, she interned at the prestigious Oak Ridge National Laboratory for three summers. At Oak Ridge she worked on a Navy project involving sonar signal processing, and based on this experience, she decided to pursue graduate studies in signal processing. After finishing her bachelor's degree in electrical engineering, she went on to graduate school at MIT. Wage’s advisor recommended that she apply to the joint program MIT has with Woods Hole Oceanographic Institution. Read more about research at sea
Student’s Robotic Mower Reaches Far Beyond the Lawn
Mason graduate student Jason Force disdains the practice of bagging grass and throwing it in a landfill as environmentally unfriendly. So he designed an easier, greener way to mow. Force, who received his BS in electrical engineering from George Mason University in 1996 and is currently working on his master’s in electrical engineering at Mason, has come up with a concept for the E-mow Harvester. This self-navigated, robotic mower operates much like the popular Roomba vacuums that propel themselves through your house and suck up dirt. But imagine if, instead of running on batteries, your Roomba ran on dirt itself. That’s the concept behind the E-mower, which uses grass trimmings for fuel. Read more about the mower.
Mason Professors’ Technology Detects Weapons Before They’re Fired
How would the course of history have been changed if assassins’ weapons had been detected before they were fired? From Abraham Lincoln in 1865 to Archduke of Austria Franz Ferdinand in 1914 to the Kennedys and Martin Luther King Jr. in the 1960s, shootings of high-profile figures in public places have started wars and ended movements. Two George Mason University professors are shaping future history by developing a pre-shot weapons detector that can identify the location of a brandished gun before the shooter fires a first shot, as well as during a subsequent firefight. The detectors could one day make schools and workplaces safer, better protect deployed military members and serve as an extra layer of security for heads of state.
