Research ArticleOpen accessIn the abstractDye Removal from Aqueous Solution by using Adsorption on Treated Sugarcane BagasseS. Saiful Azhar, A. Ghaniey Liew, D. Suhardy et al.The use of cheap and ecofriendly adsorbents has been studied as an alternative substitution of activated carbon for the removal dyes from wastewater. Adsorbents prepared from sugarcane baggase-an agro industries waste was successfully used to remove the methyl red from an aqueous solution in a batch reactor. This study investigates the potential use of sugarcane baggase, pretreated with formaldehyde (PCSB) … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 9,345 accessesView PDFCite
Research ArticleOpen accessIn the abstractHemisphere Sizing from Linear Intercept MeasurementWilfried GilleThe stereological problem of unfolding the hemisphere radius distribution from the chord length distribution is analyzed. Let a stationary isotropic process of hemispheres be given. The hemispheres have random diameters and are isotropically uniformly randomly orientated in space. A straight line probe yields a process of intercepts. The inverse problem of re-obtaining the size distribution of the hemispheres in terms … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractFLANN Detector Based Filtering of Images Corrupted by Impulse NoiseBanshidhar Majhi, Mowafak FathiWe present a novel non-linear scheme for image restoration based on neuro-detector using Functional Link Artificial Neural Network (FLANN) followed by an improved spatial filter. The method is applied to images corrupted by impulse noise with varying strengths and different noise probability. The neural detector is based on the concept of training or learning by examples. When trained properly, the … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Input Queuing Packet SwitchAzeddine Bilami, Mustapha Lalam, Mohamed BenmohammedMany Architectures of Internet routers, ATM and Ethernet switches have been proposed and analysed in literature. Theoretically reliable and valid solutions have been developed to achieve high performances, but a lot of them are not feasible in practice for commercial and technological reasons.

Research ArticleOpen accessIn the abstractEstimation of Vibrations in Switched Reluctance Motor DrivesS. Balamurugan, R. ArumugamThis study discusses a simple algorithm for estimation and reduction of Vibrations in a Switched Reluctance Motor (SRM) using magnetic circuit simulation in MATLAB/SIMULINK Environment. A Non-linear model is developed using magnetic circuit equations, wherein non-linearity is added using a inductance profile with back EMF. Dynamic characteristic of the SRM is simulated and the same is being verified experimentally. In … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Solar Radiation SystemM.S. Alam, Sushanta Kumar Saha, M.A.K. Chowdhury et al.In this research work, a mathematical model for simulation of the solar radiation system has been developed by using a system dynamics methodology. Bangladesh is used here for model validation. The simulated results obtained from this model have compared with the experimental results and found reasonably a good agreement. Therefore the performance of the model is to be expected as … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,695 accessesView PDFCite
