Collapse Button Quick Abstract
Variation reduction of Turn Around Time (TAT) in a manufacturing line is one of the important issues for line optimization. In a manufacturing line with many sequential process steps such as semiconductor fabrication, it is not easy to find the root causes of the TAT variation because (1) there might be a big time gap (more than 30 days) between cause and effect, and (2) there are so many machines (or tools) related with a process. The purpose of this paper is to propose a data mining based method to identify the root cause of TAT variation. We also aim to validate the performance of the proposed method through a simulation study.

Collapse Button Quick Abstract
For the purpose of combination of the basic and academic frontier knowledge by the application of the theory of constructivist learning in order to trace the rapid development of microelectronics, Academic frontier-based approach (AFA) is presented. The learner-centered instructional approach is valuable for promoting active learning by involving learners in learning academic frontier topics in an open-ended and collaborative environment. The design and implementation enrich the teaching modes and the content of the key curriculums in depth. It is effective in achieving positive and higher cognitive goals.

Collapse Button Quick Abstract
Academic Frontier-based Approach (AFA) is a student-centred instructional approach used to promote active and deep learning by involving students in investigating academic frontier issues in a collaborative environment. In this paper, we discuss the student surveys conducted at the end of the study period to solicit feedback from students on their learning experience. It is suggested that AFA takes the students as the center, consolidates the academic knowledge of the students. Through the teamwork and autonomous learning, students know more about the frontiers of science and technology and open their horizon. In addition, the ability of language organization, speech, compressive resistance, communication and cooperation are all increased. Furthermore, students’ interest in studying is increased because of the autonomous learning. It is expected the popularization of the consecutive courses will certainly improve these important abilities further more. And it is hopeful that students will take advantage from the sustainable ability of autonomous learning in their future career life.

Collapse Button Quick Abstract
Traditional component description methods lack sufficient semantic information. It is difficult for users to find suitable components to match their requirements. And it is also difficult in doing automatic composition and verification of components. Furthermore, the component trustworthiness is an important factor that must be considered during component composition process. Feature-Oriented Domain Analysis (FODA) that uses features and relations between features to describe the problem domain can provide necessary supports to component composition. This paper focuses on component functional semantics and component trustworthiness. A feature meta-model is proposed to provide sufficient semantic information, and trustworthiness is taken into account in the feature meta-model. Based on feature meta-model, it presents the component composition algorithm. Finally, an application of the approach in the credit evaluation domain is presented.

Collapse Button Quick Abstract
Computer aided color design is one of the hotspots in industrial design area. Based on current color configuration research, this paper focuses on knowledge representation and reasoning of color design for air-nailer color configuration system. Firstly, color representation including color type and color value is discussed. Secondly, color reasoning based on HSV space among main color, first assistant color and second assistant color is investigated. At last, the application is represented, which has been tested efficiency and accurate in air-nailer color design.

SIMULATION OF FOREST EVOLUTION - Effects of Environmental Factors to Trees Growth

Collapse Button Quick Abstract
Out of the complexity and variety of plant communities, it is a challenging task to simulate the structure and dynamics of plant communities. In this paper we simulate and visualize the evolution of forests by the tree growth model influenced by the environmental factors. The environmental factors we considered include illumination, terrains and resource competition among trees. We develop our tree growth model based on the forest gap model by effectively incorporating the above environmental factors. The system is implemented with Visual C++ 6.0 and OpenGL. We compare the growth of trees (their heights and DBHs) which are of different ages or located in different regions. We also show changes of trees distribution within certain landscape for a long period of time (more than two hundred years). The illuminating and interesting experimental results show that our simulation technique is effective.

Collapse Button Quick Abstract
Mapping between ontologies is the major bottleneck in semantic integration. In this paper, we present MCMA, a mediator-centric mapping architecture that facilitates the integration between ontologies of interrelated companies. In MCMA, different ontologies are mapped through some middle concepts and the Mapping Service acts as a bridge to connect them. As a mediator, the provider of Mapping Service is interested in a specific area and offers some common ontologies for participators to reuse. On the assumption that each individual ontology may reuse or make reference to common definitions, some mapping relations can be defined conveniently. Based on these basic mapping relations, the Mapping Service infers more middle-concept oriented mapping relations and organizes them in a layered manner. We present the idea of combining heuristics or machine-learning techniques with common ontology approach in the mapping discovery.
