Undergraduate: Explore Electrical Engineering

Andrew Hajj '14

“This summer I was given the great opportunity to work with Dr. Yan Luo as an intern. I was not sure what to expect, but after a week of learning Linux and playing with Android phone systems, I was assigned multiple responsibilities in various projects. A project that we are working on in the lab will later go towards creating a bracelet that will serve to monitor heart rate; when a phone is swiped over it, heart rate data will be transferred to the phone and make a chart that can be easily emailed to a doctor. One of my jobs in the project is to design an Android application that will make the phone communicate to a tag in the bracelet. The big personal motivating factor in the project is that my mom has had some heart issues and had to wear an EKG machine around for a few weeks. It was very loud and bothered her, making her find it very inconvenient and annoying. My hope is that when the project is complete, people can wear the bracelet rather than those machines.”

“For my REU, I worked at the CACT (Center for Advanced Communications and Telecommunications) where the specialization is in acoustics and waves. My research deals with applying an acoustic wave onto a spherical object and observing the scattering that results from passing through the object. This is done through experimentation and simulation from coding. Scattering has medical applications that can be used to detect for diseases such as cancer and osteoporosis. My REU has been a wonderful learning experience; being a freshman I was taught from the ground up by research advisors. In the CACT, there were plenty of grad students who could offer advice and assistance. My research advisor, Prof. Kavitha Chandra, has even signed me up to do a presentation at an ASA (Acoustical Society of America) conference.” Crisna Nguon
"My internship this summer has been educational so far. The first thing I learned was how to use a Linux-based operating system, which I had never used before. After learning how to use Linux, I learned how to write programs using FORTRAN. After that I ran two experiments with another undergraduate named Chrisna. In the first experiment, we used a resonating tube to measure the distances to the maximum and minimum amplitudes of the sound wave being generated inside of the tube. In the second experiment, we put a piece of foam inside the tube and calculated the specific acoustic impedance of the foam by measuring how much of the sound wave was absorbed or reflected by the foam. I then presented the results of the second experiment to some of the other students and the professors to get feedback on my presentation and the experiment. I also wrote a technical paper on the results of the second experiment using a program call Latex. The next thing I did was to write a code in FORTRAN that simulated the scattering field generated when a sound wave hits a sphere. I just started my final project for the summer. I have to figure out how an acoustic wave will scatter when it hits a wedge shaped object. Over all, I think that the co-op experience has been good so far. I have learned new things as well as how research is done, so it will help me in the long run.” Tim Pflanz
