Research ArticleOpen accessIn the abstractEVALUATION OF THE ADEQUACY OF THE WIND SPEED EXTRAPOLATION LAWS FOR TWO DIFFERENT ROUGHNESS METEOROLOGICAL SITESDalila Khalfa, Abdelouaheb Benretem, Lazher Herous, Issam MeghlaouiIncreasing knowledge on wind shear models to strengthen their reliability appears as a crucial issue, markedly for energy investors to accurately predict the average wind speed at different turbine hub heights and thus the expected wind energy output. This is particularly helpful during the feasibility study to abate the costs of a wind power project. The extrapolation laws were found … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Modeling for Traffic Noise in Urban AreaFrancis Cirianni, Giovanni LeonardiTraffic noise can be classified among the worst factors in terms of damage to people’s health and well-being. The trend of noise pollution modeling variable from the smart result of classic regressive models in the performance of many assessment models based on mathematical expressions, genetic algorithms and neural networks (of GRNN type, General Regression Neural Network). A methodological approach for … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tools Model for Runoff EstimationM. Hosseini, M.S.M. Amin, A.M. Ghafouri, M.R. TabatabaeiProblem statement: The most of the distributed or physically-based hydrologic and water quality models from developed countries are not directly applicable in developing countries due to both lack of data and different climatic conditions. Hence, there is a need for a study to be conducted a catchment of developed countries. Approach: From a review of various models to estimate runoff … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Applicability of Landslide Databases for Hazard Management Using Objective and Subjective Models: Australian Geoinformatic CaseM. OwneghProblem statement: In order to assess the applicability of Australian landslide databases as a hazard management support system, current hard and soft literature and data sources were screened. This assessment resulted in the selection of four main data bases including national landslide database (A), Peril Aus ІІ (B), the Cities project (C) and analytical study of Fell (D). Approach: In … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 10,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractVulnerability Assessment of Power System Using Radial Basis Function Neural Network and a New Feature Extraction MethodAhmed M.A. Haidar, Azah Mohamed, Aini HussainVulnerability assessment in power systems is important so as to determine how vulnerable a power system in case of any unforeseen catastrophic events. This paper presents the application of Radial Basis Function Neural Network (RBFNN) for vulnerability assessment of power system incorporating a new proposed feature extraction method named as the Neural Network Weight Extraction (NNWE) for dimensionality reduction of … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adjustable Sample Size Estimation Model for Usability AssessmentHaidar S. Jabbar, T.V. Gopal, Sattar J. AboudUsability assessment plays a fundamental role in discovering usability problems and the determination of the level of usability for a given software product. One crucial aspect in every usability assessment is the estimation of the sample size desired for a software product. Once we start estimating the sample size needed for a usability assessment, a baffling question comes in mind: … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Plasticity- Induced Fatigue Crack Closure with Singular ElementR. Rahgozar, H. Saffari, R. TabatabaeiDeveloping a new method is presented to compute crack opening values in planar geometries using the crack surface nodal force distribution under minimum loading as determined from finite element analyses (FEM). In this technique, two-dimensional elastic-perfectly plastic finite element analyses of middle-crack tension (MT) geometry is conducted to study fatigue crack closure and to calculate the crack opening values under … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,850 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Quantitative Assessment Model For Usability EngineeringHaidar S. Jabbar, T. V. Gopal, Sattar J. AboudMany different quantitative assessment models have been proposed to measure and report the usability of a general software product for various business and design purposes. However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experienced … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractDFT Based Electrophilicity Index and QSAR study of Phenols as Anti Leukaemia AgentFarhan A. Pasha, Hemant K. Srivastava, Yakoob Beg, Pashupati P. singhDensity Functional reactivity indices based QSAR study of 49 phenol derivatives is presented in this paper. Two different models to describe the anti leukaemia activity of phenols have been made. First QSAR model includes molecular properties like molecular weight (Mw), hardness (η), chemical potential (μ), total energy, and electrophilicity index (ω). Various regression models have been made and regression quality … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 7,587 accessesView PDFCite
