From the AEM Website: Dr. Ketema’s research broadly in the area of dynamics. He has studied the dynamics of active materials such as shape memory alloys especially regarding their use for the purpose of vibration damping and control. Dr Ketema has also done research in optimal trajectory generation for unmanned aerial vehicles, dynamics and stability of formations, orbital mechanics, and the mechanics of human walking. In particular, current research topics include optimal transfers between relative orbits of space vehicles, and the use of kinetic models of human gait for step-size determination for use in pedestrian navigation systems and related applications.
From the AEM Website: Professor Shield's research program focuses on understanding the effects that microstructures in modern materials have on the overall behavior of these materials and on their fracture properties. The materials under study include single crystals of shape-memory and other copper-based alloys, as well as novel materials with both magneto-elastic and shape-memory behaviors. Experimental work concentrates on observing the microstructures that form under various types of loading and at the tips of cracks. Single crystals are studied to isolate the microstructural behaviors from the grain-to-grain interactions that occur in polycrystalline materials. Models are then developed that allow the observed microstructures to be predicted and their effects on overall behavior of these materials to be understood. The basic understanding developed by this work will allow the actuators, sensors and other applications that employ these and other similar materials to be improved and designed more reliably. This work is done in collaboration with Professors Leo and James.
From the AEM Website: Professor Linares’s research interests are state and parameter estimation, and uncertainty quantification theory with a focus on the development of methods relevant to space situational awareness, vehicle attitude estimation, vehicle formation flight, small satellite systems, and autonomous navigation. He has applied these approaches to many practical aerospace problems; most notably orbital debris tracking and characterization, and precise satellite formation flight. He is interested in addressing theoretical and technical challenges in the fields of multiple object tracking, uncertainty quantification of high dimensional systems, and non-Gaussian nonlinear systems. He is also interested in the design and development of technologies for precise and robust attitude estimation and formation flight of small satellite systems.
From the AEM Website: Professor Weyrauch serves as Industrial Professor of Design, which involves teaching and consulting to the AEM design classes: AEM 4331 and 4333. He uses his 40 years of industry experience in aerospace research and product development to help students determine the best ways to execute design projects and how to develop good team working relationships. Professor Weyrauch also participates in outreach activities at local schools on his experience in developing the space shuttle in the 70s and early 80s. His formal academic background is in aeronautical and astronautical engineering with an emphasis in control systems. He has worked for 4 major aerospace companies in his industrial career: McDonnell Douglas, Honeywell, Rockwell Collins, and Alliant Techsystems.
