Nokia Distinguished Lecture: Bill Spencer on Smart Sensing Technology Smart Sensing Technology: A New Paradigm for Structural Health Monitoring Bill Spencer Department of Civil & Environmental Engineering University of Illinois at Urbana-Champaign Abstract: The ability to continuously monitor the integrity of civil infrastructure in real-time offers the opportunity to reduce maintenance and inspection costs, while providing for increased safety to the public. Furthermore, after natural disasters, it is imperative that emergency facilities and evacuation routes, including bridges and highways, be assessed for safety. Addressing all of these issues is the objective of structural health monitoring (SHM). Smart sensors densely distributed over structures can provide rich information for structural health monitoring using their sensing, computational, and wireless communication capabilities. Though smart sensor technology has seen substantial advances during recent years, implementation of smart sensors on full-scale structures has been limited; interdisciplinary efforts to address issues in sensors, networks, and application specific algorithms have only now begun to germinate. Following an overview of these issues, a new paradigm for structural health monitoring employing a network of smart sensors will be presented. Because of its ability to meet the demands of data intensive applications such as SHM, Intels Imote2 is adopted for this research. The performance of the ...

Distinguished Teaching Award champ 2007, Wei-Chau Xie, Faculty of Engineering

Waterloo civil engineering professor Wei-Chau Xie admits that his subject - applied mechanics - can be tough. Luckily for his students, he has a talent for breaking down complex problems into simpler components, and for demonstrating abstract concepts in a visual way. Often his explications are carried out in chalk on the blackboard — "an old-fashioned skill, but very important." To motivate his students, Xie tries to put himself in their shoes. "Why do I need to learn about differential equations?" he asks himself. To bring abstract ideas to life, he finds concrete applications. For example, he shows how to use differential equations to model the effect of a strong wind on the CN Tower. Xie is known as a teacher who respects his students, cares for their well-being, and encourages them to ask questions. "For me," he says, "there is no question that is too small or too big."
