In this study, we present a sub-swarm based particle swarm optimization algorithm for niching (NSPSO). The NSPSO algorithm is capable of locating and maintaining a sufficient number of niches throughout the execution of the algorithm. The niches which are identified are then exploited by using a sub-swarm strategy which tries to refine the niche and converge to an optimum solution. NSPSO is capable of locating multiple solutions and is well suited for multimodal optimization problems. From the experimentation results, we have observed that NSPSO is quite efficient in locating both global and local optima. We present a comparison of the performance of NSPSO with NichePSO and SPSO.

Under the circumstance of collaborative research & development of PLM platform-based networked products, the demands on browse and check of WEB-based CAD model are strong. Based on the study of the distributed agent technology, the framework visualized conversion technology of distributed agent-based CAD model was developed, and verification technical route of neutral visualized conversion was designed for the heterogeneous CAD model. In accordance with the requirements of the development and implementation of an enterprise-level PLM system, the study was made to apply the distributed software agent technology into the neutral-format conversion from various CAD models (***/E, UG and CATIA) with software agent. With the integration of department-level PDM and enterprise-level PLM, the concentrated effective management of neutral visualized files from different CAD models could be well achieved. Besides, the conversion of Pro/E is presented as an example in this paper to provide a detailed description of the configuration and flow-process of the visualized conversion based on software agent. According to the results of verification, the feasibility of such technology framework and technical route was demonstrated to provide a minimized dependence on the network bandwidth and a better collaborative efficiency.

Harnessing and countering inappropriate Internet use to prevent children from viewing inappropriate at home, Internet cafe¿ and to generate awareness of potential dangers from some Web sites and certain computer game pose to children and Internet users. In order to prevent children from exposure to inappropriate internet content and to promote confident and safe use of the Internet, government and private sector should get involved. This research is focus on the survey from Internet and game online users in Thailand in general. It has generated greater awareness of Internet danger as number of Internet users has increased and beneficial to the expanding community of Internet, computer users and society in general.

This article presents a precise synchronization algorithm based on status tracking and locking mechanism. Tracking execution state of triple computer and running state of time base counter through dual state machine not only can implement precise synchronization of TMR computer, making status synchronization precision and time-base synchronization precision below 30ns, but also save valuable interconnection resource, reduce implementation cost and other overhead of system resources.

In this paper, two problems in publishing syllabus information for inter-university credit exchange systems are discussed. The first is overhead cost in preparing and publishing syllabi of the systems every year. The second is that the Website presenting the syllabi lacks a search facility that allows a student to find the courses satisfied by complex search condition. In order to solve the above problems, an XML-based syllabus repository system (XSRS) which integrates syllabus data from affiliated universities is proposed. In order to minimize the impact of implementing this system on faculty staff operations, a technique that can extract syllabus data from the documents edited by some office software is also presented.
