Researchers at the University of Nevada, Reno explored the feasibility of a self-sensing adaptive bridge bearing system. In this system, rubber bearings and sensors made of a magnetorheological elastomer (MRE) (or controllable rubber) respond to loads and vibrations through automated changes in stiffness. The system has a wireless, self-sensing cap

Public transit systems can improve the community – even for those who never use the bus! Young people, older people, people with disabilities, and those without car access can maintain their independence. Transit can reduce air pollution by taking cars off the road. In addition, transit can boost property values, attract new businesses, and generat
