Research ArticleOpen accessIn the abstractHyperspectral Imagery for Mapping Disease Infection in Oil Palm Plantation Using Vegetation Indices and Red Edge TechniquesHelmi Zulhaidi Mohd Shafri, Nasrulhapiza HamdanProblem statement: Large scale plantation of oil palm trees requires on-time detection of diseases as the ganoderma basal stem rot disease was present in more than 50% of the oil palm plantations in Peninsular Malaysia. Approach: To deal with this problem, airborne hyperspectral imagery offers a better solution in order to detect and map the oil palm trees that were … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 10,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,167 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal-Mechanical Analysis of a Different Leadframe Thickness of Semiconductor Package under the Reflow ProcessS. Abdullah, M. F. Abdullah, A. K. Ariffin, A. JalarThe copper-based leadframe is practically proven effective in the thermal and reliability of a Quad Flat No Lead (QFN) three dimension (3D) stacked-die semiconductor package. Reducing the copper thickness is understood to present various thermal and reliability failure mode and mechanisms, such as die cracking and delamination. However, no in-depth study has been pursued in order to determine the capability … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralization Aspect of Neural Networks on Upgrading Assimilation Structure into Accommodating SchemeWaleed, A. J. Rasheed, Hamza A. AliProblem statement: Generalization feature enhancement of neural networks, especially feed forward structural model has limited progress. The major reason behind such limitation is attributed to the principal definition and the inability to interpret it into convenient structure. Traditional schemes, unfortunately have regarded generalization as an innate outcome of the simple association, referred to by Pavlov and had been modeled by … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeanness Achievement through People Development System in Implementing Lean Process ManagementA. P. Puvanasvaran, C. H. Tay, M. H.M.A. Megat et al.Problem Statement: Many organizations fail to unlock the infinite potential of their workforce. In that case there will be more overhead, with more layers of management, which in turn could cause slower reaction times in fast changing business. Employees should only start, run and optimize the process, even developing themselves with the aid of People Development Systems (PDS), when they … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeoradar Measurements for the Snow Cover DensityA. GodioGround Probing Radar (GPR) devices is adopted for the analysis of thickness and the mechanical properties (density) of the snow cover in some test site in Alps, in Northern Italy. The performances of standard radar systems for the snow cover characterisation are analysed, the main aim is to assess the reliability of the method to estimate the snow density, the … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Methyl Tert-Butyl Ether (MTBE) Contaminated Water by Using In situ Catalytic and Biological Combined TechniquesA. Nikpay, H. Kazemian, M. SadeghiThe hydrolysis reaction of Methyl Tert-Butyl Ether (MTBE) into biodegradable products was studied on as-synthesized and commercial H-MFI zeolites. The effect of synthesis procedure and SiO2/Al2O3 ratio was investigated. The results obtained were indicated that H-MFI zeolites were effective in MTBE hydrolysis and increasing of the Si/Al ratio promotes the hydrolysis reaction. The amount of produced TBA was always lower … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling, Simulation and Group Control of Distributed Static Series CompensatorsPoria Fajri, Saeed Afsharnia, Daryoush Nazarpour, Mohammad Ali TavallaeiThis study investigates the new concept of Distributed Static Series Compensator (DSSC); a small, light weight cylinder that clamps directly onto the transmission line conductor and has the ability to alter the impedance of the power lines in order to increase power transfer capability and maximize economic value of the transmission system. A graphic-based simulation model of the DSSC is … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 19 Dec 2008 · 7,658 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Sulfur Dioxide (SO2) Concentration Levels from the Mina Al-Fahal Refinery in Oman Using Artificial Neural NetworksSabah A. Abdul-Wahab, Saleh M. Al-AlawiIn this investigation, two Artificial Neural Network (ANN) models were applied for predicting ground-level sulfur dioxide (SO2) in the Sultanate of Oman in order to provide an early warning advisory for the protection of public health. The objective of the first model (Model I) was to use ANN to predict sulfur dioxide (SO2) levels at certain receptors from the Mina … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,385 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Photooxidation Pathways of Dicarboxylic Acids in Atmospheric DropletsL.M. Yang, L.E. Yu, M.B. RayLow molecular weight (LMW) dicarboxylic acids (DCAs) have received increasing attention because of their hygroscopic properties and capability of acting as cloud condensation nuclei (CCN). Based on the concentration profiles of intermediates identified during laboratory photooxidation of C7-C9 DCAs in a liquid-phase reaction system, chemometric analyses were conducted to examine the degradation pathways of DCAs for the formation of secondary … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,497 accessesView PDFCite
