Research ArticleOpen accessIn the abstractTwigX-Guide: Twig Query Pattern Matching for XML TreesSu-Cheng Haw, Chien-Sing LeeThe growing importance of XML and the lack of efficient solutions for managing and querying XML data have led to the development of hybrid systems. We present a hybrid system, TwigX-Guide; an extension of the well-known DataGuide index and region encoding labeling to support twig query processing. With TwigX-Guide, a complex query can be decomposed into a set of path … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,082 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Novel Reconfigurable Execution Core for Merged DSP MicrocontrollerA. K. Rath, P. K. MeherThe study presents an execution core which can be reconfigured either for calculation of digital convolution or for computation of discrete orthogonal transform by appropriate local buffer initialization of processing cells. It is shown that the data flow pattern can be changed by a single bit control signal. The proposed core can be connected to port 1 of Intel 8051 … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,487 accessesView PDFCite
Research ArticleOpen accessIn the abstractOpen ended-coaxial Cable Measurements of Saturated Sandy SoilsAlberto GodioThe application of electromagnetic methods in the radar and micro-wave frequency band allows the fluid content of soils to be estimated; the heuristic or physically-based models permit to relate the observed electrical permittivity of the soils with the porosity and fluid saturation. The role of the effect of the free water and bound water in the overall electromagnetic behaviour of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractChi Square Feature Extraction Based Svms Arabic Language Text Categorization SystemAbdelwadood Moh’d A MESLEHThis paper aims to implement a Support Vector Machines (SVMs) based text classification system for Arabic language articles. This classifier uses CHI square method as a feature selection method in the pre-processing step of the Text Classification system design procedure. Comparing to other classification methods, our system shows a high classification effectiveness for Arabic data set in term of F-measure … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 11,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomedicine and Informatics Model of Alzheimer's DiseaseKang Cheng, Chang-Hua ZouIn a perspective of biomedicine and informatics, the mechanism of Alzheimer's, senile amnesia, or other aging-associated and cognitive impairment related diseases involve four important informative processing procedures: propagation, consolidation, retrieval and cognition, In this study, we systematically model the four procedures based on published experimental data. When modeling the propagation, we develop an equivalent circuit of biological membrane to describe … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 28 May 2007 · 6,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Merged DSP Microcontroller for Embedded Systems using Discrete Orthogonal TransformA. K. Rath, P. K. MeherIn this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be possible to … …Journal of Computer Science, Vol. 2, Issue 5 · 31 Aug 2006 · 6,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Method for Tagging Arabic TextYamina Tlili-GuiassaMany natural language expressions are ambiguous and need to draw on other sources of information to be interpreted. Interpretation of the word ﺗﻌﺎون to be considered as a noun or a verb depends on the presence of contextual cues. This study proposes a hybrid method of based- rules and a machine learning method for tagging Arabic words. So this method … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,705 accessesView PDFCite
