Prof. David Luneau

Prof. Luneau continued his research work in the area of “Remote Camera Sensing” with primary focus on the design and development of small wireless cameras to monitor nest activities for some of the endangered bird species. In this respect he collaborates with other researchers from Arkansas and around the country, who benefit from the advancement in camera and communication technology in their research. He and his collaborators have published their findings in suitable periodicals. These include the following: Luneau, M.D. Jr., Noel, Brandon L. “A wireless video camera for viewing tree cavities,” Journal of Field Ornithology, 81(2):176–185, 2010.

Dr. Mo Bakr

Dr. Bakr’s research activities centered around senior projects and included:

1. “Mold Sealing Application.” The project was jointly undertaken and funded by LM Wind Power, which manufactures wind turbine blades. The purpose of the project was to improve and simplify the mold sealing process in preparation for resin casting.

2.”Fixture Design to Improve the Productivity of Mid-Cabin Curtain Production”

The project was jointly undertaken with a local business aircraft finishing company. The project was considered to be a labor and cost saving measure and was aimed at producing mid cabin curtains for a line of aircrafts produced by the company.

3 “Mini Baja Race Car Project” The project involved evaluation of the previous race performance, identifying systems and components on the vehicle that did not perform well enough in the past, perform the necessary technical and stress analysis, redesign and reconstruct these systems and components, and test the vehicle on a simulated race track to evaluate the design improvements.

4. “Design, Construction and Testing of a Four-Point Vehicle Low-Lift System.” A team of three seniors in mechanical engineering technology conceived the need, analyzed the market demand and conceptually designed a system consisting of four electric-powered scissor-type jacks that are remotely controlled from a portable central platform. The project involved the design, development, construction and testing of a prototype.
