Research ArticleOpen accessIn the abstractA Comparative Analysis of the Entropy and Transition Point Approach in Representing Index Terms of Literary TextHayati Abd Rahman, Shahrul Azman NoahProblem statement: Concept hierarchy is a hierarchically organized collection of domain concepts. It is particularly useful in many applications such as information retrieval, document browsing and document classification. Approach: One of the important tasks in construction of concept hierarchy is identification of suitable terms with appropriate size of domain vocabulary. Results: One way of achieving such a size is by … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,678 accessesView PDFCite
Research ArticleOpen accessIn the abstractContrasting Three Popular Explanations for the Muller-Lyer IllusionMichael R. WoloszynProblem statement: Using the method of adjustment, participants compared the line lengths of ‘dumbbell’ and ‘spectacle’ versions of Muller-Lyer (circles and ovals at the endpoints in place of arrowheads). Approach: Three popular competing explanations for the illusion (conflicting cues, misapplied size constancy scaling and confusion hypothesis) make differing predictions concerning the pattern of change in illusion strength when the bounding … …Current Research in Psychology, Vol. 1, Issue 2 · 31 Dec 2010 · 22,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlling Label Size Increment of Efficient XML Encoding and Labeling Scheme in Dynamic XML UpdateMeghdad Mirabi, Hamidah Ibrahim, Ali Mamat et al.Problem statement: In order to facilitate XML query processing, labeling schemes are used to determine the structural relationships between XML nodes. However, labeling schemes have to reliable the existing nodes or recalculate the label values when a new node is inserted into the XML document during XML update process. EXEL as a labeling scheme is able to remove relabeling for … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,421 accessesView PDFCite
Research ArticleOpen accessIn the abstractGermination Ecology of Rhanterium epapposum Oliv.Sameeha Zaman, Shyamala Padmesh, Harby TawfiqProblem statement: Rhanterium epapposum, locally called Arfaj is the national flower of Kuwait. The current situation of Rhanterium epapposum is quite critical in most areas of Kuwait. In fact it has completely disappeared from most parts of the country due to a combination of overgrazing, collecting for firewood and off road driving. Approach: Rhanterium epapposum is an excellent species for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,623 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of the Cuttings Cleaning During the Drilling OperationHussain H. Al-Kayiem, Nadia Mohd Zaki, Muhamad Z. Asyraf, Mahir Elya ElfeelProblem statement: Oil well cleaning is the ability of a drilling fluid to suspend and transport drilled cuttings from the down hole (bit face) to the surface. The cleaning performance was affected by many factors such as fluid viscosity, annular flow velocity, angle of inclination and drill cuttings size and shape and. Approach: Navier-Stoke equations, the continuity equation and the … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part I: Fluidization Behavior and Characteristic VelocitiesV. S. Chok, A. Gorin, H. B. ChuaProblem statement: Palm shell on its original state cannot be fluidized solely. However, mixing palm shell with a second fluidizable material can facilitate proper fluidization. Approach: The minimum and complete fluidization velocity (Umf and Ucf) for sand/palm shell binary mixtures had been studied in a partitioned reactor known as Compartmented Fluidized Bed Gasifier (CFBG). The pilot scale reactor ID is … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,221 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Aerosol Particle Size at High Polluted Region in the World Using Direct Solar Radiation Measurements: Helwan as a Case RegionU. Ali RahomaProblem statement: Particle counting and sizing of atmospheric aerosols by electro-optical methods are complex and absolute interpretation of measurements is difficult, so, the scattered light varies in a complicated manner with the system of optics as well as with the size and physical characteristics of particles. Approach: The estimation of the air aerosol number concentration variation was carried out in … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 8 May 2010 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractArabic Speaker Recognition: Babylon Levantine Subset Case StudyMansour Alsulaiman, Youssef Alotaibi, Muhammad Ghulam et al.Problem statement: Researchers on Arabic speaker recognition have used local data bases unavailable to the public. In this study we would like to investigate Arabic speaker recognition using a publically available database, namely Babylon Levantine available from the Linguistic Data Consortium (LDC). Approach: Among the different methods for speaker recognition we focus on Hidden Markov Models (HMM). We studied the … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 7,246 accessesView PDFCite
