The engineering and applied science has long been recognized as the foundation for moving the world forward and shaping the world of tomorrow. As unexpected technology advances in recent decades, many researchers, scientists, engineers and academics in the engineering and applied science area notice a need to discuss practical and critical challenges in the field. They would also want to share the latest research results and present the effective solutions. Accordingly, the International Conference on Engineering and Applied Science (ICEAS) 2012 achieves to serve the needs and is going to take place during 24-27 July 2012 in Beijing, China. The symposium offers a professional platform across Civil Engineering, Material Science, Electrical and Electronic Engineering, Chemical Engineering, Mechanical Engineering, Computer and Information Sciences, Environmental Science, Biomedical Engineering, Nanotechnology, and many other topics about engineering and applied science.
