This paper presents a surface reconstruction algorithm from unorganized point sets based on region-growing and Gabriel. It begins with computing the Gabriel graph of the sampling point sets, and then performs a region growing process to `grow' into a triangulated surface from the Gabriel structure. Compared with the traditional approach based on Delaunay and region-growing, the proposed algorithm requires only a subset of the Delaunary structure and needs no Voronoi information, so it is more efficient. Experimental results show that this method is robust and effective on handling surfaces with complex topology, boundaries, and even non-uniform sample points.

There is an increasing interest in recent years for querying and ranking XML documents. In this paper, we present a new framework for querying and ranking schema-less XML documents based on concise summaries of their structural and textual content. We introduce a novel data synopsis structure to summarize the textual content of an XML document for efficient indexing. More importantly, we extend the traditional vector space model to effectively rank XML documents over the proposed data synopses. We conduct extensive experiments over XML benchmark data to demonstrate the advantages of the indexing scheme and the effectiveness of our ranking scheme. We also compare our framework with Lucene to demonstrate our extended TF*IDF scoring function is effective.

In this paper, the exponential synchronization of a class of Cohen-Grossberg neural networks with delays and diffusion terms is discussed. By using Lyapunov functional method and Sobolev inequality, some sufficient conditions are given to ensure the exponential synchronization of the drive-response cellular neural networks with delays and diffusion terms.
Synchronization is very important for the efficient processing and transmission of information across the nervous system. Synchronization processes are ubiquitous in nature and play a very important role in many areas...
