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 · 11,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Power Hardware Implementation of High Speed FFT CoreM. Kannan, S. K. SrivatsaApplications based on Fast Fourier Transform (FFT) such as signal and image processing require high computational power. This paper proposes the implementation of radix-4 based parallel-pipelined Fast Fourier Transform processor which incorporates a low power commutator, butter-fly with multiplier-less architecture. The proposed parallel pipelined architectures have the advantages of high throughput and low power consumption. The multiplier-less architecture uses shift … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,227 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeamless Handoff Using Mailbox ApproachManpreet Singh, Rajneesh GujralMobile IP is used to keep track of location information and make the data available to the mobile devices anytime, anywhere. Mobile IP has been widely accepted but lacks in providing seamless handoff. We have proposed a framework for wireless network that uses a flexible and adaptive mailbox-based scheme. In this scheme a mailbox associated with each mobile node while … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Determinants of Deprivation in Jordan: Empirical StudyMohammed Issa ShahateetThe objective of this study was to determine and explain the factors that affect deprivation in Jordan. To do so, this study constructs and tests a model that determines the factors, which affect deprivation. It employs an econometric analysis to examine the relationship between some main socioeconomic variables and the status of deprivation in Jordan. It looks at how changes … …Journal of Social Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Ant Algorithm for Swarm-Based Image ClusteringSalima Ouadfel, Mohamed BatoucheA collective approach to resolve the segmentation problem was proposed. AntClust is a new ant-based algorithm that uses the self-organizing and autonomous brood sorting behavior observed in real ants. Ants and pixels are scatted on a discrete array of cells represented the ants’ environment. Using simple local rules and without any central control, ants form homogeneous clusters by moving pixels … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Value of Serologic Tests for Diagnosis and Follow up of Patients having BrucellosisNidia E. Lucero, Sandra M. Ayala, Gabriela I. Escobar, N R. JacobThough diagnosis of human brucellosis is accurate when the causal agent is isolated, this procedure is not always successful and the most of patients are diagnosed on the basis of rising titres of antibodies in serum. The classical tests used for detection of antibodies to S-Brucella sp., include Rose Bengal (RBT), buffered plate antigen (BPAT), serum agglutination (SAT), 2-mercapto-ethanol (2MET) … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 7,446 accessesView PDFCite

Research ArticleOpen accessIn the abstractPacked Forest Chart ParserQi Haoliang, Li Sheng, Yang Muyun, Zhao TiejunPacked forest chart parser, like the traditional chart parsing algorithm, uses charts to store all the information produced while parsing to avoid redundant works. Its advantage over the traditional chart parser was the packed forest representation. The algorithm not only shares the non-terminal categories as what was done in the shared parse forest, but also shares the leftmost common elements. … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarth-To-Space Improved Model for Rain Attenuation Prediction at Ku-BandMandeep Singh Jit Singh, S. S.I. Hassan, M. F. Ain et al.A model for predicting rain attenuation on earth-to-space was developed by using the measurement data obtained from tropical and equatorial region. The proposed rain attenuation model uses the complete rainfall rate cumulative distribution as input data. It was shown that significant improvements in terms of prediction error over existing attenuation model obtained. …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,725 accessesView PDFCite
