Research ArticleOpen accessIn the author namesImage Reconstruction Algorithm for Electrical Charge Tomography SystemM. F. Rahmat, M. D. Isa, K. Jusoff et al.Problem statement: Many problems in scientific computing can be formulated as inverse problem. A vast majority of these problems are ill-posed problems. In Electrical Charge Tomography (EChT), normally the sensitivity matrix generated from forward modeling is very ill-condition. This condition posts difficulties to the inverse problem solution especially in the accuracy and stability of the image being reconstructed. The objective … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 8,330 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling and Controller Design of an Electro-Hydraulic Actuator SystemM. F. Rahmat, S. Md. Rozali, N. Abdul Wahab et al.Problem statement: Electro-hydraulic actuators are widely used in motion control application. Its valve needs to be controlled to determine direction of the motion. Mathematical modeling is a description of a system in terms of equations. It can be divided into two parts; physical modeling and system identification. The objective of this study was to obtain mathematical model of an electro-hydraulic … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 11,183 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Investigation of Factors Influencing Design Team Attributes in Green BuildingsMohamed S. Elforgani, Ismail RahmatProblem statement: Buildings contribute significantly global environmental problems. Better design can minimize these impacts. Design Green Building (DGB) aims to reduce buildings' impact on the environment. However, the green design performance depends on design team attributes. In addition, the Governance System (GS) and Client Quality (CQ) as external factors have influence on Design Team Attributes (DTA) of green building. Approach: … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,962 accessesView PDFCite
Research ArticleOpen accessIn the author namesExponential-Hyperbolic Model for Actual Operating Conditions of Three Phase Arc FurnacesMahdi Banejad, Rahmat-Allah Hooshmand, Mahdi Torabian EsfahaniProblem statement: The Electric Arc Furnace (EAF) is a non-linear load and creates power quality related problem. Therefore, accurate modeling of the EAF is essential. Approach: In this study, an optimal model for EAF in time domain called exponential-hyperbolic, was proposed to describe the behavior of the EAF for all of the operating conditions and it does not need the … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the author namesWhy Do People Use Their Cars: A Case Study In MalaysiaAbdalla Nurdeen Kamba, Riza Atiq O.K. Rahmat, Amiruddin IsmailIn Malaysia, the rapid increase in the use of own transport prompted by inadequate public transport has resulted in increased traffic congestion, accidents, inadequate parking space and air pollution among other evils. This study sought to identify the factors preventing own transport users from shifting to public transport and to develop model shift from car to public transport in order … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 9,182 accessesView PDFCite
Research ArticleOpen accessIn the author namesInfluences of Conventional Feeding Regimen on the Productivity of Bali Cattle in SamarindaHamdi Mayulu, Siti Maisyaroh, Surya Nur Rahmatullah, Irsan TricahyadinataThe pattern of Bali cattle farming in Indonesia is dominated by traditional livestock systems which are identical to local feeding (without taking into account the needs of cattle. This study aims to determine the effect of conventional feeding on the productivity of Bali cattle in Lempake Village, North Samarinda Sub-district, Samarinda City. The study targeted male Bali cattle and measured … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 27 Oct 2022 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the author namesBAYESIAN MODEL AVERAGING WITH MARKOV CHAIN MONTE CARLO FOR CALIBRATING TEMPERATURE FORECAST FROM COMBINATION OF TIME SERIES MODELSHeri Kuswanto, Mega Rahmatia SariGlobal warming is an important issue related to the climate and weather forecast. It is shown by significantly increasing the atmospheric temperature level. Hence, improving the forecast accuracy of temperature is an important issue. The forecast is commonly done by performing a deterministic forecast meaning that the system will generate a point forecast without taking into account the uncertainty induced … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 29 Nov 2013 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of Antimalaria Activity and Acute Toxicity of Xetospongia spSyamsudin Abdillah, Rahmatul Wahida Ahmad, Yatnita Parama Cita, Noriah Mohd NoorWe investigated the in vivo activity of extract of Xetospongia sp against Plasmodium berghei Strain ANKA and acute toxicity in mice. The ethanolic extracts of the Xetospongia sp (50-400 mg kg-1 day) were screened for blood schizonticidal against P. berghei strain ANKA in mice during early and established infections. Acute toxicity of extracts of Xetospongia sp at the dose 5000 … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 2 · 2 Sep 2013 · 7,796 accessesView PDFCite
Research ArticleOpen accessIn the author namesTwo-Step Robust Diagnostic Method for Identification of Multiple High Leverage PointsArezoo Bagheri, Habshah Midi, A.H.M. Rahmatullah ImonProblem statement: High leverage points are extreme outliers in the X-direction. In regression analysis, the detection of these leverage points becomes important due to their arbitrary large effects on the estimations as well as multicollinearity problems. Mahalanobis Distance (MD) has been used as a diagnostic tool for identification of outliers in multivariate analysis where it finds the distance between normal … …Journal of Mathematics and Statistics, Vol. 5, Issue 2 · 30 Jun 2009 · 8,306 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Robust Rescaled Moment Test for Normality in RegressionMd. Sohel Rana, Habshah Midi, A.H.M. Rahmatullah ImonProblem statement: Most of the statistical procedures heavily depend on normality assumption of observations. In regression, we assumed that the random disturbances were normally distributed. Since the disturbances were unobserved, normality tests were done on regression residuals. But it is now evident that normality tests on residuals suffer from superimposed normality and often possess very poor power. Approach: This study … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 8,260 accessesView PDFCite
