Reluctance actuators are thought to be a good solution for the nano-precision stage to provide high acceleration as a kind of feedforward actuator in the next generation lithography. However, hysteresis has a significant impact on the accuracy of reluctance actuators. There are many methods to model the hysteresis, among which Prandtl-Ishlinskii (PI) model is the most popular one. To effectively control...
Comprehensive two-dimensional liquid chromatography (2DLC) offers a number of practical advantages over optimized one-dimensional LC in peak capacity and thus in resolving power. The traditional “product rule” for overall peak capacity for a 2DLC system significantly overestimates peak capacity because it neglects under-sampling of the first dimension separation. Here we expand on previous work by...
In the IPv4 wireless network, the quality of the communications between the wearable computers or the mobile nodes is slow and the wearable computers cannot achieve in the sub-seamless switching between LANs. According to the three function entities of mobile IPv6 the protocol stack software is divided into three major modules, and proposed design program and the division of sub-module based on the...

In this paper, operators are encapsulated by services in algorithms for large-scale optimization problems and the services are deployed in distributed systems. Response time is an important factor for the performance of cooperative services. The message parse time is analyzed. Initial service accessing time is the main overhead for service calling. To decrease both the initial time and the response...
