Abstract: To increase the utilization efficiency of LNG cold energy, this paper analyzes LNG regasification process basing on energy-grade analysis. The result shows that comprehensive utilization both of doing work and heat transfer is the most efficient. Moreover, this paper proposes a chart to select a suitable cold energy utilizaiton way.

Abstract: A self-adaptive forecast & optimal control method for grinding wheel in-feed is presented, it can control grinding wheel plunge by using the new program of grinding process, and can compensate availably the size errors produced by the elasticity deflection of the grinding system and the deference of work-pieces rough and the wear of the grinding wheel, et al. The result of computer simulation and real testing indicate that this method can improve grinding quality.

Abstract: A web based remote monitor & control system for grinding process is presented. In this system, OPC/Socket drive technology, CAN bus technology, B/S structure, Java Applet and ActiveX etc. are used to realize the remote monitor & control, and grinding processes in different place can be monitored and controlled by remote grinding expert only through browser, so it overcomes the shortage that the grinding quality depends on skilled workers and variants with grinding operators. The data processing and feature releasing method of AE signals in grinding process also be discussed. The grinding state feature information can be updated automatically, and be browsed by remote experts through running the ActiveX in the browser. Therefore, it is of important significance for improving workers’ working environment and work-piece quality.
