Dynamics of Smart Structures

Dr Ranjan Vepa is lecturer in avionics in the Department of Engineering at QMUL. Since joining in 1984 he has taught undergraduate avionics related courses, and conducted research into the aspects of the design, analysis, simulation, and implementation of avionics and avionics-related systems including non-linear aerospace vehicle kinematics, dynamics, vibration, control and filtering. Dr Ranjan Vepa is a Chartered Engineer and a Member of the Royal Aeronautical Society. In addition to journal and conference papers, he has contributed to the textbook Application of Artificial Intelligence in Process Control and is currently completing a research monograph on Biomimetic Robotics: Mechanisms and Control, due to be published in June 2008 by Cambridge University Press.

"Examples of structures assembled from smart materials demonstrate basic principles and illustrate properties of commonly used smart structure prototypes. Extending beyond the needs of a two-semester or one-year course, the text can be used for a senior undergraduate or graduate course." (Book News, September 2010)
