Applying Collision Avoidance Expert System to Navigation Training Systems as an Intelligent Tutor
To enhance the skills of captains and improve the existing training technologies, it is very important and urgent to research and develop an intelligent navigation training system. Therefore we propose to incorporate a collision avoidance expert system into real-time ship handling simulator to provide intelligent decision-making support for navigation training. The intelligent tutor aims to assist the trainee to master necessary skills for handling ship in complex navigating environments such as open sea, restricted waterway, and rough sea conditions by sharing multiple captains' experience. In this paper, the developed collision avoidance expert system will be outlined, then the proposed intelligent decision-making support for navigation training will be presented in details.

A Simulation-Based Procedure for Expert System Evaluation
It is well recognized that the evaluation of the knowledge-based system is very important and difficult in the development of expert systems in the domains such as aviation and navigation. To alleviate some of the difficulties, and to reduce the development cost, the authors proposed an evaluating procedure based on simulation. The proposed procedure was designed to validate the functionality and capability of an expert system that was developed to provide decision-making support in ship navigation. In this paper, the developed expert system for collision avoidance is first outlined, and the procedure to evaluate the developed expert system by using a simulation-based approach is presented in details. It is also concluded that the simulation-based procedure is feasible and effective for evaluating expert systems in a number of different domains.

On Implementation of a Scalable Wallet-Size Cluster Computing System for Multimedia Applications
In order to obtain a low-cost, low-power consumption and small sized digital home processing center, especially for multimedia applications, we propose a scalable wallet-size cluster computing system in this paper. Such system uses low-cost, low-power consumption and small sized microprocessors as computing nodes to form a cluster system. 
 
The main reason why we are interested to investigate and build such system is to increase the computing power and to accelerate the H.264 video processing. We analyzed the H.264 decoder scheme and distributed the most heavy-load computations in the decoder scheme to each computing node (or microprocessor) of the cluster system for the processing of signals, in parallel. To run multimedia applications in this cluster system, an efficient real-time video processing is implemented.

Applying Multi Agent Technology to Supply Chain Management
Supply Chain Management (SCM) is extremely important to the manufacturing and retailing industries. Profitability of enterprises in these two industries depends on the efficiency and effectiveness on they manage their supply chains. Information technology has been a key element in supporting supply chain management. As the access to the Internet becomes easier, managers are able to access real-time data and use decision support tools to support their decision making. In this paper, we investigate how multi-agent technology and constraint network can be integrated together to improve the efficiency and transparency of supply chain management. A multi-agent based supply chain management system has been developed to support communication, coordination, collaboration, and operation of different entities in supply chains. Which enabled the warehouses and plants to query and share information. A constraint network model has been applied to model the objectives and constraints of each entity in supply chains. Two experiments have been conducted to evaluate the usefulness and performance of the system with participation of a retailing firm. The results indicated that the proposed system has several benefits. For example, improve efficiency by saving time and efforts for decision makers as well as improve the quality and responsiveness of decision making by value-added services, such as, bullwhip detection agent.

A Parallel Loop Self-Scheduling on Extremely Heterogeneous PC Clusters
Cluster system is viable and less expensive alternative to SMP. However, the approaches to deal with scheduling and load balancing on heterogeneous cluster computer system are not mature. Self-scheduling schemes which are suitable for parallel loops with independent iterations on heterogeneous cluster computer system have been designed in the past. However, these schemes, such as FSS, GSS and TSS, can not achieve load balancing in extremely heterogeneous environment. In this paper, we propose a heuristic approach to solve parallel regular loop scheduling problem on extremely heterogeneous PC cluster environment.

SDMI-based rights management systems
Building digital rights management (DRM) systems for electronic commerce is still a complex task because such systems are usually required to manage a large set of different media contents, rights information, and enabling technologies. The Secure Digital Music Initiative (SDMI) was proposed to provide a secure environment in which rights management is performed for music distribution through the Internet. Rights management in SDMI is implemented by digital watermarking, but it is not the responsibility of SDMI to provide guidelines for the design of digital watermarks and to explore other potential benefits of using digital watermarks for the music distribution business. This paper fills this gap by proposing an SDMI-based rights management system. The proposed rights management system can support basic SDMI functions and non-SDMI features such as video. A prototype of the SDMI-based rights management system has been developed and the interfaces of the major components are presented.

A bandwidth-based polling scheme for QoS support in Bluetooth
A flexible bandwidth management scheme namely Bandwidth-based Polling (BBP) for Bluetooth is proposed. A framing structure of time is defined in BBP, and the master allocates proper number of slots for each active slave in a frame. BBP allows the master to poll a slave more than once to achieve high flexibility for bandwidth allocation. The calculation of the polling time as well as the payload type for a slave is according to the bandwidth requirement of the slave and the limit of the frame size controlled by the master. Extension of BBP for supporting slaves with the SCO link and slaves without bandwidth requirement (best-effort slaves) is also proposed. Simulation results have shown the efficiency and fairness of BBP in bandwidth management. The flexibility of bandwidth allocation depends on the maximum polling time preset by BBP. A larger maximum polling time makes the higher flexibility of bandwidth allocation at the expense of a longer latency before reaching the equilibrium state. Analysis of the impact of the maximum polling time on bandwidth allocation is also presented in the paper.
