Research ArticleOpen accessIn the keywordsDamping of Generator Oscillations Using an Adaptive UPFC-based ControllerD. Nazarpour, S. H. Hosseini, G. B. GharehpetianIn this study a UPFC-based non-linear adaptive controller is proposed and designed to damp generator oscillations. The adaptive controller design is based on determination of control signal using a new linear quadratic pole placement control law and identification of power system parameters with recursive least squares method with adaptive directional forgetting factor. A new model of UPFC has been introduced … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,764 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Roles of Some Antecedents of Broadband User Behavioural Intention among Students in the Rural Areas through PLS-SEMIshola D. Muraina, Wan Rozaini Bt Sheik Osman, Azizah AhmadThe insufficient broadband enabled-services in the rural areas have been identified among the reasons that prolong the behaviour of rural dwellers on the use of low-band internet while government agencies have started initiations to increase the use of broadband in the rural area. However, previous studies have failed to identify the roles played by antecedents of broadband user behavioural intention … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 11 Nov 2015 · 6,721 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDeterminants of Technical Efficiency on Pineapple FarmingNor Diana Mohd Idris, Chamhuri Siwar, Basri TalibThis study analyzes the pineapple production efficiency of the Integrated Agricultural Development Project (IADP) in Samarahan, Sarawak, Malaysia and also studies its determinants. In the study area, IADP plays an important role in rural development as a poverty alleviation program through agricultural development. Despite the many privileges received by the farmers, especially from the government, they are still less efficient. … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 30 Apr 2013 · 7,980 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Analysis of Operationalization and Acceptability of Business to Business Transaction: A mixed Method ApproachYusuf Muhammad-Bashir Owolabi, Ahamed Kameel Mydin Meera, Gairuzazmi Mat Ghani et al.Business to business barter exchange is a form of transaction that is gaining popularity during the economic downtown despite the fact that money exchange supersede the traditional barter exchange due to a number of inherent problems it has. This study explores the operation and user’s acceptance of business to business barter exchange in Malaysia that has made barter exchange feasible … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 30 Jul 2012 · 7,727 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTruncated Estimate in Log-Binomial Model: Algorithm and SimulationLuyan Dai, Yang Li, Ye ShenProblem statement: Relative risk has concrete meanings of comparing two groups and measuring the association between exposures and outcomes in medical and public health studies. Log-binomial model, using a log link function on binary outcomes, is straightforward to estimate risk ratios, whereas generates boundary problems. When the estimates are located near the boundary of constrained parameter space, common approaches or … …Current Research in Biostatistics, Vol. 2, Issue 1 · 7 May 2012 · 8,291 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn Three-Way Unbalance Nested Analysis of VarianceSmaila S. Sanni, Eugene C. UkaegbuProblem statement: In this study, we give a simple analytically tractable procedure for solving three-way unbalanced nested Analysis of Variance (ANOVA). In many realistic situations, unbalanced design was unavoidable due to natural constraints and missing data. Approach: Here, we present a comprehensive approach for addressing solutions of problems arising from unbalanced nested ANOVA. We consider the F-statistics under the different … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 10 Dec 2011 · 7,717 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Approach for 3D Range Image Segmentation using Gradient MethodDina A. Hafiz, Walaa M. Sheta, Sahar Bayoumi, Bayumy A.B. YoussefProblem statement: Segmentation of 3D range images is widely used in computer vision as an essential pre-processing step before the methods of high-level vision can be applied. Segmentation aims to study and recognize the features of range image such as 3D edges, connected surfaces and smooth regions. Approach: This study presents new improvements in segmentation of terrestrial 3D range images … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 19,592 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAcoustic Echo Cancellation: Dual Architecture ImplementationB. Stark, B. D. BarkanaProblem statement: With the rise in mobile communication, it is becoming more frequent to use a communication device in an enclosed noisy environment, such as a subway or in a lobby. In this setting however, the received microphone is severely degraded by the echo from the speaker and background noise. The audio processing necessary to clarify the desired speech can … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the keywordsShort-Term and Medium-Term Load Forecasting for Jordan's Power SystemI. Badran, H. El-Zayyat, G. HalasaSeveral electric power companies are now forecasting electric loads based on conventional methods. However, since the relationship between loads and factors influencing these loads is nonlinear, it is difficult to identify its nonlinearity by using conventional methods. Most of papers deal with 24-h-ahead load forecasting or next day peak load forecasting. These methods forecast the demand power by using forecasted … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,081 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTax Exportability in Tourism MarketMohammad Mohebi, Khalid Abdul Rahim, Lee Chin, Khairil Wahidin AwangProblem statement: Tax incidence is a basic topic in public economics as the tourism industry is an increasingly major contributor to government revenue.
