Research ArticleOpen accessIn the abstractQuery Translation using Concepts Similarity Based on Quran Ontology for Cross-Language Information RetrievalZulaini Yahya, Muhamad Taufik Abdullah, Azreen Azman, Rabiah Abdul KadirIn Cross-Language Information Retrieval (CLIR) process, the translation effects have a direct impact on the accuracy of follow-up retrieval results. In dictionary-based approach, we are dealing with the words that have more than one meaning which can decrease the retrieval performance if the query translation return an incorrect translations. These issues need to be overcome using efficient technique. In this … …Journal of Computer Science, Vol. 9, Issue 7 · 21 Jun 2013 · 7,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputational Analysis of Particulate Flow in Expansion ChannelNor Azwadi Che Sidik, Leila JahanshalooComputational prediction of fluid-solid particle interaction in an expansion horizontal channel with wide range of Reynolds numbers. Lagrangian-Lagrangian numerical technique to predict the movement of solid particle. The method is based on mesocale scheme of lattice Boltzmann method for prediction of fluid dynamics and second Newton’s law for the dynamics of solid particles. The flow behaviour at the downstream of … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 20 Apr 2013 · 6,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Markov Switching Regime Model of Malaysia Property CycleAbdul Mutalib Beksin, Bawa Chafe AbdullahiProblem statement: Non-linear models such as the Markov Switching regime (MS) method of modeling business cycles, in principle can be used to model property cycle. Approach: The MS model can distinguish property cycle in recession and expansion phases and is sufficiently flexible to allow different relationships to apply over these phases. The Malaysian property cycle was modeled using a MS … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractA GA Based Transmission Network Expansion Planning Considering Voltage Level, Network Losses and Number of Bundle LinesS. Jalilzadeh, H. Shayeghi, M. Mahdavi, H. HadadianTransmission Network Expansion Planning (TNEP) was studied considering voltage level, network losses and number of bundle lines using decimal codification based genetic algorithm (DCGA). TNEP determines the characteristic and performance of the future electric power network and directly influences the operation of power system. Up till now, various methods have been presented for the solution of the Static Transmission Network … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractClosed Form Solution to an Optimal Control Problem by Orthogonal Polynomial ExpansionMohammad Ali Tavallaei, Behrouz TousiIn this study the use of orthogonal polynomials for obtaining a close form solution to optimal control problems with a weighed quadratic cost function, is proposed. The method consists of using the Orthogonal Polynomials for the expansion of the state variables and the control signal. This expansion results in a set of linear equations, from which the closed form solution … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Probability Density Function of the Test Statistic for One Nonlinear GLR Detector Arising from fMRIFangyuan NanRecently an important and interesting nonlinear generalized likelihood ratio (GLR) detector emerged in functional magnetic resonance imaging (fMRI) data processing. However, the study of that detector is incomplete: the probability density function (pdf) of the test statistic was draw from numerical simulations without much theoretical support and is therefore, not firmly grounded. This correspondence presents more accurate (asymptotic) closed form … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 7,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Electricity Product by Increasing Water Volume During FreezingA. Arab, B. Alinaghi, M. R. RezaieElectricity production process by the use of water expansion during freezing. By use of a closed volume such as piston and cylinder. The volume increase of ice could be transformed linearly and cause piston displacement, by the use of cold resource and heat resources. This process is possible where boarding temperature difference is high and water temperatures reach below 0°C … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Heavy Metals in the Surface Sediments of the Main Wadis in the Region of Meknes-MoroccoA. Lammini, A. Dehbi, H. Omari, A. AbdallaouiBecause of their growing demographic and industrial expansion, the urban areas of the city of Meknes are likely to disturb the ecological balance of watercourse. In the present work, we had evaluate the degree of sediment’s contamination by heavy metals (Al, Cd, Cu, Fe, Mn, Pb and Zn) in the main wadis of the Meknes region (Boufekrane, Wislane and Toulal) … …Current Research in Geoscience, Vol. 4, Issue 2 · 29 Apr 2015 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractDETECTION OF LAND USE AND LAND COVER CHANGES IN DIRAB REGION OF SAUDI ARABIA USING REMOTELY SENSED IMAGERIESR. Madugundu, K. A. Al-Gaadi, V. C. Patil, E. TolaKnowledge of Land Use and Land Cover (LULC) changes is important for many planning and management activities. It is thought to be an essential element for modeling and understanding the major land forms, especially in arid regions like Saudi Arabia. This study investigates the LULC changes in Dirab region of Saudi Arabia between 1980 and 2010, using Landsat TM/ETM+images. After … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 30 Jan 2014 · 8,013 accessesView PDFCite
