Research ArticleOpen accessAll words, across the recordA Computational Trust Model for Collaborative VenturesMohd Mokhtar, Weigang WangProblem statement: The conceptual notion of trust and its underlying computational methods has been an important issue for researchers in electronic communities. While the independent trust evaluation is suitable in certain circumstances, such unilateral process falls short in supporting mutual evaluation between partners. Perceived reputation, the depth and breadth of trust, Trust Perception (TP), Repeat Collaborators at a Threshold (RCT) … …Journal of Computer Science, Vol. 8, Issue 9 · 15 Aug 2012 · 7,206 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFinding What You Expect to See: Theoretical Modeling in PsycholinguisticsKathleen AhrensProblem statement: Theories of language processing rely upon experimental evidence to support or reject their hypotheses. Yet it is often the case that conflicting theories flourish alongside each other for decades, with voluminous experimental evidence to support their respective hypotheses. Approach: In this study, I suggest it is imperative for researchers to move beyond their own experiments and results to … …Journal of Social Sciences, Vol. 8, Issue 3 · 18 May 2012 · 8,227 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Comparative Study in Classification Techniques for Unsupervised Record Linkage ModelMohammadreza Ektefa, Fatimah Sidi, Hamidah Ibrahim et al.Problem statement: Record linkage is a technique which is used to detect and match duplicate records which are generated in data integration process. A variety of record linkage algorithms with different steps have been developed in order to detect such duplicate records. To find out whether two records are duplicate or not, supervised and unsupervised classification techniques are utilized in … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 8,199 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThree-Dimension Coronary Artery Tree Curvature ConfirmationHassan H. Khalil, Rahmita O.K. Rahmat, D. M. Zamrin et al.Problem statement: Three-Dimension (3D) reconstruction is one of the vital and robust tools that provide aid in many fields, especially medicine. This article is about 3D shape similarity and it presents a comparison approach between principal curvature methods of 3D output. Our approach follows the concept of using the gray scale value as the z dimension and the other approach … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,767 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTone Question of Tree Based Context Clustering for Hidden Markov Model Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: In HMM-based Thai speech synthesis, tone is an important issue that brings about the intelligibility of the synthesized speech. Tone distortion resulted from imbalance of the training data should be appropriately treated. Approach: This study described an HMM-based speech synthesis system for Thai language. In the system, spectrum, pitch and state duration are modeled simultaneously in a unified … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,820 accessesView PDFCite

Approach: AIDS, ROTTERDAM, CBS and NBR models was compare together and Sur method was applied for estimating of systems, too. Results: Results of study showed cream and fresh fruits have smallest and largest income elasticity, respectively. Also, cream, bread, dairy, egg, fresh vegetables, … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,991 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApproximation of Iteration Number for Gauss-Seidel Using Redlich-Kister PolynomialM. K. Hasan, J. Sulaiman, S. Ahmad et al.Problem statement: Development of mathematical models based on set of observed data plays a crucial role to describe and predict any phenomena in science, engineering and economics. Therefore, the main purpose of this study was to compare the efficiency of Arithmetic Mean (AM), Geometric Mean (GM) and Explicit Group (EG) iterative methods to solve system of linear equations via estimation … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 8,138 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,007 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBackscattered Acoustic Energy by Monobubbles Experimental Approach and Statistical Study of the AttenuationAli Khelil, Claude ManteProblem statement: As the number of air bubbles in the sea is very high, they are so many acoustic diffusers who make illegible the recordings the purpose of which is to quantify the alive bodies. The signals backscattered by air bubbles constitute a parasite in offshore recordings and must be eliminated. It is planned to finalize techniques allowing the localization … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,579 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Covers and Rainfall on Soil and Water Conservation Using a Tilting Flume ModelS. Compliew, L. Suwanchai, N. KrongwiengThe effect of stone and vegetative covers was evaluated for soil and water conservation in a waterway on salty soils in the Northeast of Thailand. Experiments were conducted on a hydraulic tilting flume under simulated unit flow (120 and 45 cm2s-1), rainfall (120 mm/hr) and slope (0, 1.2,1.4,1.6,1.8,2.0, 2.2, 2.4, 2.6, 2.8 and 3.0%) conditions.
