"From The Ground Up" Rethinking Engineering Education In The 21st Century, Richard Miller
Richard K. Miller
The engineering challenges of the 21st century will require leaders capable of addressing the Grand Challenges of our time: global security, health, sustainability, and the joy of living. In addition to solid preparation in traditional STEM1 subjects, these leaders will need a deep understanding of non-technical issues surrounding technological invention to achieve the desired systems outcomes and avoid unintended consequences. The educational implications require preparing students early in their program for integrative systems thinking across academic disciplines, political boundaries, and time zones. Instead of continuing with the current natural science-centered foundation for a modern engineering education and attempting incremental change, …

This paper reports some of the results of an ongoing analytical and ex perimental study into the control of building-like structures subjected to nonstationary ran dom excitations such as earthquakes. The structural model used resembles a 5-story build ing about 2.5 meters high. The building model was subjected to a variety of direct-force excitations. The control algorithm used employs an adaptive structural member at a prede termined location in the model in order to attenuate the structural response relative to the moving building foundation. An electromagnetic actuator is used to generate the required control faces in the "smart" member. Among …
