This article analyzes the interoperability problem of Agent deeply. It first discusses the main research work about agent interoperability,namely OMG's MAF specification and the set of specifications of FIPA,and points out their drawbacks. Then a research model covering the main aspects of interoperability in Agent environment is brought up,and a reference model for agent system is also provided,which fully corresponds with the research model for agent interoperability.The two models have nice universality and adaptability,and provide a practical reference for building an Agent system with good interoperability.展开更多

Based on the field monitoring data of lateral soil pressure on the side wall of the open caisson for the southern anchorage of the Maanshan Yangtze River Highway Bridge, the statistical result of the side friction under different buried depths of the cutting edge of the open caisson was back-analyzed; and the side friction distribution of the large open caisson was underlined. The analysis results indicate that when the buried depth of the cutting edge is smaller than a certain depth H0, the side friction linearly increases with the increase in the buffed depth. However, as the buffed depth of the cutting edge is larger than H0, the side friction shows a distribution with small at both ends and large in the middle. The top of the distribution can be regarded as a linear curve, while the bottom as a hyperbolic curve. As the buffed depth of cutting edge increases continuously, the peak value of the side friction linearly increases and the location of the peak value gradually moves down. Based on the aforementioned conclusions, a revised calculation mode of the large open caisson is presented. Then, the calculated results are compared with the field monitoring data, which verifies the feasibility of the proposed revised calculation mode.展开更多

Thus, JXTA, a new P2P technology, emerged as the times require. This paper ex-plores P2P and JXTA in particular, and then gives an applied example about it. At last, similarities and differencesbetween JXTA and other typical distributed computing technologies and their application ranges have been deeply in-vestigated.展开更多
