This paper presents a fuzzy controller for nonlinear uncertain systems. The fuzzy controller has a data base engine and fuzzy inference part to predict the control law. The data base engine can learn the controlled system from a test signal. The fuzzy inference engine is used to generate the control input from maximum similarity inference rules. Finally, the control performance are demonstrated by simulation studies.

In this paper, we consider fault-tolerant ring embedding problem in the clustered-star graph. We present a ring embedding strategy based on the series of dimension expansion operations and the even distribution of faulty nodes into sub-stars. In our embedding, a fault-free ring of length m(n-1)! -2f can be constructed, provided that the number of faulty nodes, f is no more than n-3 and also any one (n-1)-sub-stars cannot contain all faulty nodes in an (n-1)-dimensional clustered-star graph of order m. This implies that our result is optimal in the worst case from tow points of views. First, the maximum number of allowable faulty nodes is bounded by the two less than the minimum degree of a given graph in the worst case because all faults are incident to one special node. Second, the twofold factor of missing nodes per faulty node is inevitable in the resulting cycle because the clustered-star graph is bipartite property, This result can be applied to the multicating applications that use the underlying cycle properties on the multi-computer system.

A new adaptive control structure is proposed for a nonlinear system using indirect identification neural network. A neural network is used to identify the feedforward nonlinearity of nonlinear system and construct a feedback controller for a unknown nonlinear system through indirect dynamic system identification. A reference model, which is introduced to incoporate a prior knowledge of controlled system, generates the teaching signal to indirect identification neural network and offers the dynamic linear control strategy. The tracking performance and adaptivility are demonstrated by simulation studies.

It is important to support consistency control of integrated production databases where interrelated application modules are concurrently executed. This thesis designs a new active consistency control method integrating a database and rulebase. It automatically executes rules for fixing consistency violations. When a database is updated, a trigger procedure is automatically executed to update its corresponding repository (which describes metadata about the integrated databases). The checking of consistency violations is realized by the monitor method, which is triggered by the updates of the repository. The monitor method then executes the related methods or invokes rules for fixing consistency violations.

Banking Cybermediaries on the Internet:New Roles and Characteristics

Lee, Yeong-hoon 부산외국어대학교 정보과학연구소 2000 情報科學論集 Vol.2 No.-

The advent of the Internet has led to many predictions about the way that business will be conducted in the future, especially in the area of finance. The roles and characteristics of banking entities in the new medium have not yet been determined. The purpose of this paper was to determine which factors were more important to success for those bank entities doing business on the Internet. Online banking cybermediaries such as Security First Network Bank (SFNB) and Citibank were examined to identify important factors. First, however, the theoretical foundation of the paper was described and the new marketing model for todays highly competitive and global financial marketplace was presented. Roles, characteristics, and responsibilities of Citibank and Security First Network Banks cybermediary function were found to mirror those described in the literature. Clearly, a major responsibility is to supply needed access, support, and promotional opportunities. Both websites have indeed moved from being the keeper of money to being the gatekeepers of financial information, activities, and records. Other responsibilities were also identified: extend reach, recognize change, gain customer loyalty, allow customer comparison supply access, and create a strong brand experience for the consumer. With respect to the roles, the following were found to be important: brand promotion, technical involvement, expert assistance, inform users, provide power to consumers, serve as economic agents, capitalize on the dynamics of online communities to gain competitive edge, provide more than just assistance in information retrieval, and provide an aggregation of resources to decrease user search efforts. Other general factors were found to influence success. These included branding; full on-line service; customer service, accessibility, and navigability; enhanced technology, content, and visual expression; and produce availability and service.
