With the rapid increase in expressway mileage, accidents and casualties are increasing frequently. Expressway construction in China starts later than developed countries and lack of mature and comprehensive emergency rescue systems. There are some limitations in accident rescue process and information processing such as low coordination level between multi departments and low level of information communication and sharing. An expressway emergency rescue information management system (EERIMS) using Browser/Server framework is developed, the organizational system and rescue process of the provincial expressway system are analyzed, system design, main functional modules and technical points are described. A Case study indicates that it can improve processing and analysis capabilities of the emergency rescue information, enhance communication and sharing between departments and reduce the burden of managers.Index Terms-Expressway emergency rescue, Rescue procedure, Information management system, Framework.

Heat exchangers are commonly used in various industries. A spiral-plate heat exchanger with two fluids is a compact plant that only requires a small space and is excellent in high heat transfer efficiency. However, the spiral-plate heat exchanger is a nonlinear plant with uncertainties, considering the difference between the heat fluid, the heated fluid, and other complex factors. The fractional order derivation model is more accurate than the traditional integer order model. In this paper, a parallel fractional order derivation model is proposed by considering the merit of the graphics processing unit (GPU). Then, the parallel fractional order derivation model for the spiral-plate heat exchanger is constructed. Simulations show the relationships between the output temperature of heated fluid and the orders of fractional order derivatives with two directional fluids impacted by complex factors, namely, the volume flow rate in hot fluid, and the volume flow rate in cold fluid, respectively.
