Research ArticleOpen accessCTSS: A Tool for Efficient Information Extraction with Soft Matching Rules for Text MiningA. Christy, P. ThambiduraiThe abundance of information available digitally in modern world had made a demand for structured information. The problem of text mining which dealt with discovering useful information from unstructured text had attracted the attention of researchers. The role of Information Extraction (IE) software was to identify relevant information from texts, extracting information from a variety of sources and aggregating it … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,896 accessesView PDFCite
Research ArticleOpen accessSimplified Block Matching Algorithm for Fast Motion Estimation in Video CompressionM. Ezhilarasan, P. ThambiduraiBlock matching motion estimation was one of the most important modules in the design of any video encoder. It consumed more than 85% of video encoding time due to searching of a candidate block in the search window of the reference frame. To minimize the search time on block matching, a simplified and efficient Block Matching Algorithm for Fast Motion … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,052 accessesView PDFCite
Research ArticleOpen accessEfficient Physical Organization of R-Trees Using Node ClusteringF. Sagayaraj Francis, P. ThambiduraiR-Tree is a multidimensional indexing structure that forms basis for all the multidimensional indexing structures based on data partitioning. A number of attempts have been made in the past to improve the performance of R-Tree by manipulating the tree parameters and the data parameters. But hardly any attempt had been made to use external parameters such as disk parameters to … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,628 accessesView PDFCite
Research ArticleOpen accessLow Complexity Performance Effective Task Scheduling Algorithm for Heterogeneous Computing EnvironmentsE. Ilavarasan, P. ThambiduraiA heterogeneous computing environment is a suite of heterogeneous processors interconnected by high-speed networks, thereby promising high speed processing of computationally intensive applications with diverse computing needs. Scheduling of an application modeled by Directed Acyclic Graph (DAG) is a key issue when aiming at high performance in this kind of environment. The problem is generally addressed in terms of task … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 9,668 accessesView PDFCite
