Abstract
Our natural world is an environment that is highly changes may impact lives on a large scale, such as those caused by a Tsunami, global warming, or global dimming phenomena. Monitoring technologies have improved tremendously over the years in the hope of predicting such events. The manmade world today is also highly complex, and has become increasingly sophisticated. In the same spirit as monitoring systems for the natural world that save lives, technology has also made it possible to monitor structural stress and instabilities within buildings. Target tracking systems (Wong, 2004) using acoustics, passive infra-red, and even other modes, such as chemical compound analysis, are capable of warning against possible attacks by terrorists on our civilized world.
