In this paper, we propose a new approach to fuzzy clustering in order to handle the uncertainties in pattern recognition problems on the basis of conventional fuzzy C-means algorithm (FCM). In our approach, we define the concept of linguistic cluster center by employing the semantic structure of hedge algebra. This kind of cluster center is constructed to give the appropriate weights for each pattern of the dataset in our clustering algorithm. The parameters of hedge algbra are then optimized in the training process to obtain the suitable parameters for the dataset. We also incorporate the k-means algorithm to get better results in comparing to conventional FCM.

-Người dân hoảng loạn -Người sống không nơi ở -Người chết không nơi chông -Tình cảnh thảm sầu, kể sao cho xiết Trong tác phẩm "Sống chết mặc bay", Phạm Duy Tấn có những lời văn cụ thể, sự khéo léo trong việc vận dụng kết hợp hai phép tương phải và tăng cấp đã cho thấy bức tranh, thống khổ của nhân dân. Tác phẩm vừa là sự lên án gay gắt tên quan phụ mẫu "lòng lang dạ sói", vừa là sự bày tỏ niềm thương cảm trước cảnh khốn khổ của nhân dân.

Recently, virtual heritage has emerged as a promising technology for conservation, preservation, and interpretation of our culture and natural history. We implemented a virtual heritage system with real data acquisition and a MPEG-21 based graphics adaptation architecture for transmitting adapted 3D contents to multiple target devices. Our system consists of 3D modeling tools, 3D content authoring tools, 3D database system and 3D graphics adaptation system. In this paper, we provide a overview of our system, including our approach in 3D modeling, a web-based interactive presentation over network and proposed a graphics adaptation system within MPEG-21 framework for transmitting adapted 3D contents to multiple target devices with different user preferences.

In this paper, we propose a graphics adaptation framework with a mechanism of video streaming to overcome the shortcoming of real-time representation and interaction experiences of 3D graphics application running on mobile devices. We therefore develop an interactive 3D visualization system based on the proposed framework for rapidly representing a complex 3D scene on mobile devices without having to download it from the server. Our system scenario is composed of a client viewer and an adaptive media streaming server. The client viewer offers the user to navigate the 3D scene and interact with objects of interests for studying about them through the responded text descriptions. The server adaptively provides media contents to the client according to the user preferences, interactions, and the condition of wireless network.
