Two engineering students can add the letters “Ph.D.” to their resumes after last week’s summer hooding ceremony at Tennessee Tech University.
In a small ceremony in the president’s conference room, Zhe Chen and Ling Tang received their doctorates and their hoods, the regalia marking the degree.
“TTU is proud to award these two students with the highest degree we offer,” TTU President Bob Bell said. “The research they have done is a testament to Tech’s commitment to engineering research.”
Chen’s dissertation, “Cognitive radio network: Architecture, algorithms and testbed,” proposes ways to sense, predict and access holes in the radio spectrum with experimental evaluations for cognitive radios and suggests a system and design for a large-scale testbed. Cognitive radios automatically switch frequencies to use holes in the limited spectrum to improve efficiency. His advisor is Robert Qiu, professor in the Center for Manufacturing Research. P. K. Ragan hooded him.
Ling’s paper, “Transfer of uncertainty of space-borne high resolution rainfall products of ungauged regions,” focused on ways to monitor rainfall in areas that rely solely on satellite-based systems, which are not always accurate. Her advisor, Fasial Hossain, TTU civil and environmental engineering professor, was present at the ceremony to put on her hood.
The Ph.D. in engineering is an interdisciplinary degree program composed of chemical, civil and environmental, electrical and computer and mechanical engineering courses, as well as computer science.
The university awards doctorates three times a year: in the winter, spring and summer. The summer ceremony is usually the smallest of the three.
