The application on AES S-box shows the SAC and PC characteristics of the eight AES Boolean functions.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.

This is because new services such as video on demand and remote meeting systems require better QoS. However, the problem of QoS routing is difficult and to find a feasible route with two independent path constraints is NP-complete. Therefore, QoS routing algorithms for high speed networks must be adaptive, flexible, and intelligent for efficient network management. In a previous work, we proposed a genetic algorithm (GA) based routing method. This method used only the delay time as a routing parameter. In this paper we improve the previous work in three aspects. The new QoS routing method uses two QoS parameters for routing. We implemented a new tree generating algorithm which generates and reduces the tree automatically. Furthermore, we carried out the simulations for different kinds of networks. The simulation results show that the proposed method has a better performance than a conventional GA based routing algorithm.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.

The program was motivated by the need to browse the content of a web-accessible ontology server: WEB KB-2. The ontology server contains descriptions of over 74,500 object types derived from the WordNet 1.7 lexical database and can be accessed using RDF syntax. Such a structure creates complications for hyperbolic-style displays. In WEB KB-2 there are 140 stable ontology link types and a hyperbolic display needs to filter and iconify the view so different link relations can be distinguished in multi-link views. Our browsing tool, OntoRama, is therefore motivated by two possibly interfering aims: the first to display up to 10 times the number of nodes in a hyperbolic-style view than using a conventional graphics display; secondly, to render the ontology with multiple links comprehensible in that view.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.

Because the system requires and rules on data statistic often need to be changed, we must modify the data model and algorithms on statistics by changing the source codes. It will lead to frequent system update. Additionally, we must manage the data in the system and store them into the database because of the importance of data. So, how to implement the functions of data acquisition and storage based on this kind of data model is the research topic for software designers.

The differences between the two approaches arise partly from differences in strategies to suppress productivity degradation by trial and error with unknown issues in development projects. Strategies of a typical modeling intensive approach, the UP (Unified Process), and those of a typical implementation intensive approach, XP (extreme programming), are discussed. To investigate the effectiveness of these strategies, implementation productivity and interface change rate are measured on a development project under the UP. A high interface change rate and low implementation productivity are observed in classes related to the solution domain. These measurement results support the effectiveness of the \"suppression of rework\" strategy and \"suppression of change propagation\" strategy, of the UP.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.

Many presentation systems provide synchronized, sequential or concurrent, and possible interactive, transfer of multimedia data streams such as audio, video, text and annotations used with network facilities. However, our investigation of existing standards and applications for multimedia document models such as HTML, MHEG, SMIL, HyTime, RealPlay and MS Windows Media shows that these standards and application models do not provide adequate support for reuse and adaptation. Consequently, we propose a new approach for the modeling of reusable and adaptable multimedia content. We developed a comprehensive system for advanced multimedia content production: support for recording the presentation, retrieving the content, summarizing the presentation, weaving the presentation and customizing the representation. This approach significantly impacts and supports multimedia presentation authoring processes in terms of methodology and commercial aspects.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.

Component patterns are stored in the database system. Their properties and specifications are also attached to the data field of each component pattern except that of engineering components. In our approach, the recognition system adopts parallel computing, and will raise the recognition rate. Our recognition system is a client-server network structure using the Internet. The system uses a recurrent neural network (RNN) with associative memory to perform training and recognition.
