boilingAbstract
老公用英语怎么说Since Autonomous Decentralized Systems have been propod in 1977 and published [1], their technologies and applications in control and information fields have progresd and some of their technologies are approved as the de-facto standards of ODVA (Open DeviceNet Vendor association), OMG (Object Management Group), etc. Recently the ADS have been accelerated more under the unpredictable recent markets for the worldwide huge but rvice-oriented autonomous community for specific local-majority urs, and for the complex and changing system management [2]. In the systems, the ADS new paradigm is required to satisfy the heterogeneous requirements for the various autonomous systems under the evolving and to assure the systems operation.

The ADS have the goal to achieve the on-line property of fault tolerance, on-line expansion and on-line maintenance to continue the system operation even under the partial system failures, expansion/modification and test/repair. Bad on the molecular biology, ADS concept is propod and autonomy of subsystem is characterized by two of autonomous controllability to achieve its own responsibility and autonomous coordinability for mutual coordination even under any subsystem’s in-operation. The ADS take a bottom-up approach, which means that at first each subsystem exists and then the system is clarified as the results of the integration of the subsystems.
The ADS have been motivated from two aspects of the technologies advancements such as the LSI and optical fiber, and of the evolving market requirements of the on-line property. Therefore until now, the ADS technologies have been advanced in the local-area network-oriented manufacturing, railway transportation, utility management, car/satellite on-board computing, systems and so on. While, the Internet is itlf the integration of the autonomous communication subsystems (nodes) and it has been gradually expanded from the local to the global.
世上无难事只怕有心人英语2. Community
syntheticThe social and economy systems have been evolving more and the systems have been related dyna
mically through the Internet and the wide area networks. It is almost impossible to predetermine the relation between urs and rvice providers and to predict the change of the rvice contents and their integration. The urs and providers try to arch for and change to the most appropriate rvices, and, if necessary, they make the appropriate group for cooperation. Their systems are independently constructed and managed, but they are cooperating for achieving their own objectives more in this group. This group is called as Community, which consists of the autonomous members and they can cooperate through sharing the necessary information and functions. Sometime they are urs but the other time they autonomously have the roles of the providers. One provider may judge to have the other providers’ information and functions. The community technologies have been propod in the distributed transaction processing technology for the supply-chain management system [3] and in the distributed information allocation/utilization technology for the web rvice [4]. In the near future, the computing resources as well as the communication will be organized as the infrastructure community and they have to be managed as the autonomous community components. Then the urs are relead from the computing system managements, which cost nowadays reaches 80% of the IT expenditure.

The ADS have been expected for the system assurance, the efficient investment of the IT systems and the customer-oriented rvices, and the autonomous community technology is one of the new paradigms. References
