Research ArticleOpen accessIn the abstractTime Series Forecasting by using Seasonal Autoregressive Integrated Moving Average: Subset, Multiplicative or Additive ModelSuhartonoProblem statement: Most of Seasonal Autoregressive Integrated Moving Average (SARIMA) models that used for forecasting seasonal time series are multiplicative SARIMA models. These models assume that there is a significant parameter as a result of multiplication between nonseasonal and seasonal parameters without testing by certain statistical test. Moreover, most popular statistical software such as MINITAB and SPSS only has facility … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 18,295 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Docking Analysis on Natural Compounds Versus a Synthetic Drug as a Therapeutic for Acquired Immuno Deficiency SyndromeSandhya R. Nair, R. Subhashini, B. ThiagarajanProblem statement: Acquired Immune Deficiency Syndrome (AIDS) is one of the worst pandemics affecting and spreading quickly all over the world with a high mortality rate. AIDS has been able to kill so many people due to the unique property of Human Immunodeficiency Virus (HIV) virus. It attacks the immune system of the victim there by not allowing the immune … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 7,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractSkin Color Detection Model Using Neural Networks and its Performance EvaluationK. K. Bhoyar, O. G. KakdeProblem statement: Skin color detection is used as a preliminary step in numerous computer vision applications like face detection, nudity recognition, hand gesture detection and person identification. In this study we present a pixel based skin color classification approach, for detecting skin pixels and non skin pixels in color images, using a novel neural network symmetric classifier. The neural classifiers … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 8,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl of a Step Walking Combined to Arms Swinging for a Three Dimensional Humanoid PrototypeAmira Aloulou, Olfa BoubakerProblem statement: Present researches focus to make humanoid robots more and more autonomous so they can assist human in daily works like taking care of children, aged or disabled persons. In such social activities, the contemporary humanoid robots are expected to have human like morphology and gait. Studies on bipedal locomotion for humanoid robots are then part of the hottest … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractLinear Filtering for Optimized Approach in Satellite Image EnhancementPetcharat Pattanasethanon, Boonwat AttachooProblem statement: For decades, several image enhancement techniques have been proposed. Although most techniques require profuse amount of advance and critical steps, the result for the perceive image are not as satisfied. Approach: In this study, we proposed a new method to enhance the satellite image which compares two procedures using two different kinds of filtering technique with an additional … …Journal of Computer Science, Vol. 6, Issue 10 · 24 Aug 2010 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanism of Microencapsulation with Urea-Formaldehyde PolymerRochmadi, Agus Prasetya, Wahyu HasokowatiProblem statement: Microcapsule is one of important fine chemical products in the current chemical industries. Better understanding of microencapsulation process is useful to properly design of microcapsule with specific characteristics. The aim of this research is to study the mechanism of Urea-Formaldehyde (UF) microcapsules formation. Approach: Microcapsule was prepared in two steps. The first step was the preparation of oil … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of the Daily Mean PM10 Concentrations Using Linear ModelsJ. C.M. Pires, F. G. Martins, S. I.V. Sousa et al.The performance of five linear models to predict the daily mean PM10 concentrations was compared. The linear models proposed were: (i) multiple linear regression; (ii) principal component regression; (iii) independent component regression; (iv) quantile regression; and (v) partial least squares regression. The study was based on data from an urban site in Oporto Metropolitan Area and the analysed period was … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwo Mathematical Modeling Approaches for Integrating Production and Transportation Decisions in the Process IndustryMohamed K. Omar, A. AjithaIn this study we focus on coordination of the production planning of finished products and intermediate products in the process industry. The problem consists of two manufacturing facilities with similar production environment, one producing the intermediates and the other producing end products that are separated by a distance.
