This paper proposes a hierarchical clustering algorithm based on Saturated Neighbor Graph - hi-CLUBS and a new concept, natural nearest neighbor, which adopts a parameter-less algorithm of searching the natural neighbors for each point in a dataset. In the work, the Saturated Neighbor Graph is constructed by the natural nearest neighbor firstly. Then modularity is introduced into graph partitioning algorithm, with which the generated graph is partitioned into small sub-clusters without any parameters. Finally, these initial sub-clusters are repeatedly merged with another cluster according to similarity measurement based on connectivity and closeness, until the desired cluster number is reached. The results show that hi-CLUBS produces a set of final clusters achieves better quality than the traditional clustering algorithms.

This paper presents a novel scheme for accelerating ray traversal computation in ray tracing. By the scheme, a pre-computed stage is applied to constructing what is called a traversal field for each rigid object that records the destinations for all possible incoming rays. The field data, which could be efficiently compressed offline, is stored in a small number of big rectangles called ray-relays that enclose each approximate convex segment of an object. In the ray-tracing stage, the records on relays are retrieved in a constant time, so that a ray traversal is implemented as a simple texture lookup on GPU. Thus, the performance of our approach is only related to the number of relays rather than scene size, while the number of relays is quite small. In addition, because the traversal fields only depend on the internal construction of each convex segment, they can be used to ray trace objects undergoing rigid motions at a negligible extra cost. Experimental results show that interactive rates could be achieved for dynamic scenes with the effects of specular reflections and refractions on an ordinary desk PC with GPU. Copyright 2006 ACM.

As concept maps are useful for knowledge organization, representation and sharing, people used to draw concept maps by pen in their daily life. And some concept maps are closely related to physical world. In this paper, we propose a kind of context-aware hand-drawn concept map with RFID tags, which is especially useful for pen-based mobile devices. First, the structure of the hand-drawn concept map is extracted. And then users can assign RFID tags to concept nodes. With the RFID lab.led concept nodes, concept maps are linked to the physical world, which can facilitate users’ understanding and retrieval of hand-drawn concept maps.
