Research ArticleOpen accessIn the abstractSocial Interactions for Academic Purposes in Literature Classes for Non English SpeakersAi Chun YenProblem statement: This study reports how Learning Communities (LCs) and Online Learning Communities (OLCs) can improve Taiwanese EFL students’ lack of Social Interactions (SIs) and acdemic skills in literature classes (Y1, N = 40) by involving freshmen in a social process that encourages student-student and student-instructor discussion, interpretation, production and negotiation. Approach: The data collected from the database of the … …Journal of Social Sciences, Vol. 8, Issue 3 · 16 Jul 2012 · 7,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractPalmprint Recognition using Feature Level FusionR. Gayathri, P. RamamoorthyProblem statement: Palmprint based biometric method has gained high impact over the other biometric methods due to its ease of acquisition, reliability and high client acceptance. Multiple feature extraction from image gives higher accuracy of the authentication system. Approach: This study presents the palmprint based identification methodology which uses the Gabor wavelet entropy to extract multiple features existing on the … …Journal of Computer Science, Vol. 8, Issue 7 · 19 May 2012 · 6,982 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Palmprint Identification based on High Order Zernike MomentR. Gayathri, P. RamamoorthyProblem statement: Hand geometry contains relatively invariant features of an individual. Palmprint recognition is an efficient biometric solution for authentication system. The existence of several hand-based authentication commercial systems indicates the effectiveness of this type of biometric. Approach: We proposed a palmprint verification system using high order Zernike moment that was robust to rotation, translation and occlusion. Zernike moment was … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Robust Hybrid Approach to Enhance Speech in Mobile Communication SystemsManimegalai Govindan Sumithra, Keppana Gounder Thanuskodi, Bharathi DeepaProblem statement: The received voice signal in mobile communication is often disturbed by background noise and hence there is a need for good noise reduction methods for enhancing Speech. It is well known that denoising is a compromise between the removal of the largest possible amount of noise and the preservation of signal integrity. To address this issue, a new … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Interregional Commodity FlowsWirach Hirun, Sompong SirisoponsilpProblem statement: Commodity Flow Survey (CFS) was launched to collect comprehensive freight flow data throughout the kingdom of Thailand. The survey’s database is the most complete collection of commodity flow data in Thailand. The need to reveal interregional freight characteristics using available data from the CFS led to the objectives of this research. Approach: An origin destination matrix based on … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Earthquake-Induced Crest Settlements of EmbankmentsRaghvendra Singh, Debasis RoyProblem statement: Freeboard requirement, a major consideration in the design of embankment dams, is controlled to a great extent by the crest settlements during earthquakes. Approach: The parameters that influence earthquake induced crest settlement had been studied using 152 published case histories on performance of embankment dams during earthquakes. Results: Based on the results a correlation had been proposed for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 8,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multi-form Multiple Choice Editor Exam Tool Based on HTML Website and Artificial Intelligence TechniquesA. Rjoub, Y. Eyadat, A. Ghazawi et al.Problem statement: The educators argue that in the post modern world changes in the nature of work, globalization, the information revaluation and today's social challenges will all impact on educational priorities and thus will require a new mode of assessment. Approach: The objectives of this study were to: (1) Present a novel software package tool to create multiple choice and … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractFace Recognition Based on Nonlinear Feature ApproachEimad E.A. Abusham, Andrew T.B. Jin, Wong E. Kiong, G. DebashisFeature extraction techniques are widely used to reduce the complexity high dimensional data. Nonlinear feature extraction via Locally Linear Embedding (LLE) has attracted much attention due to their high performance. In this paper, we proposed a novel approach for face recognition to address the challenging task of recognition using integration of nonlinear dimensional reduction Locally Linear Embedding integrated with Local … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Spatial ARM (Spatial Association Rule Mining) for Geo-Decision Support SystemRanjana Vyas, Lokesh Kumar Sharma, U. S. TiwaryGeographical Decision Support System (Geo-DSS) is a demanding field, since enormous amount of spatial data have been collected in various applications, ranging form Remote Sensing to GIS, Computer Cartography, Environmental Assessment and Planning. Although some efforts were made to combine spatial mining with Spatial Decision Support System but mostly researchers for spatial database are using a popular data mining approach-Apriori … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractMFTPM: Maximum Frequent Traversal Pattern Mining with Bidirectional ConstraintsJiadong Ren, Xiaojian Zhang, Huili PengAn important application of sequential mining technique is maximal frequent traversal pattern mining, since users' traversal pattern and motivation are latent in session sequence at some time segment. In this paper, a Frequent Traversal Pattern Tree structure with dwell time (FTP-Tree) is designed to store, compress the session database, and simplify the configuration of dwell time thresholds during mining. A … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,530 accessesView PDFCite
