Research ArticleOpen accessIn the abstractFabrication of Single Layer SiO2 and Si3N4 as Antireflection Coating on Silicon Solar Cell Using Silvaco SoftwareA. Lennie, H. Abdullah, S. Shaari, K. SopianThe main objectives was to investigate and enhance the short circuit current density, Jsc and also to improve the efficiency of silicon solar cell by fabricating a layer of silicon dioxide (SiO2) and silicon nitride (Si3N4) coatings on silicon solar cell. This fabrication carried out on high temperature during annealing process from 800-1050°C and variable thickness of antireflection coating (ARC) … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,679 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnbalance Quantitative Structure Activity Relationship Problem Reduction in Drug DesignD. Pugazhenthi, S. P. RajagopalanProblem statement: Activities of drug molecules can be predicted by Quantitative Structure Activity Relationship (QSAR) models, which overcome the disadvantage of high cost and long cycle by employing traditional experimental methods. With the fact that number of drug molecules with positive activity is rather fewer than that with negatives, it is important to predict molecular activities considering such an unbalanced … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,707 accessesView PDFCite
Research ArticleOpen accessIn the abstractDurability Assessment of Cylinder Block for Two Stroke Free Piston Linear Engine using Random LoadingM. M. Rahman, A. K. Ariffin, S. Abdullah et al.This research presents the durability assessment of cylinder block for a two-stroke free piston engine using narrow band approach. The life prediction results are worthy for improving the component design at the very early developing stage. This approach is adequate for periodic loading, however, requires very large time records to accurately describe random loading processes. Fatigue damage in conventionally determined … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Electrical Properties by Texturing Surface on GaAs Solar Cell EfficiencyH. Abdullah, A. Lennie, M. J. Saifuddin, I. AhmadProblem statement: This project discusses on the method to resolve the optical losses problem that have been hindering the totality efficiency of the photovoltaic. Solar cell simulation could be useful for time saving and cost consumption. The Silvaco software is not widely used in designing the 2D solar cell devices because there is lots of 1D, 2D and 3D-simulation beside … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractVerifying Complex Interaction between Hardware ProcessesKiran Ramineni, Shireesh Verma, Ian G. HarrisProblem statement: Verification of correct functionality of semiconductor devices has been a challenging problem. Given the device fabrication cost, it is critical to verify the expected functionality using simulations of executable device models before a device manufactured. However, typical industrial scale devices today involve large number of interactions between their components. Complexity of verifying all interactions becomes almost intractable even … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Architecture for Improving Location Management in PCS NetworksHaidar Safa, Samuel PierreThis study proposes a new architecture for improving the location management in PCS networks. The proposed architecture employs several HLRs as opposed to one HLR in the IS-41 and GSM models. Indeed, the new architecture associates with each MU two types of HLRs ; a resident HLR that serves the location areas in which the MU often resides and a … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAdvanced Grasshopper Optimization Scheduling Algorithm (AGOSA) for Multi-Cloud EnvironmentsS. Gowri, A. SumathiThe multi-cloud scheduling problem refers to the challenging task of efficiently allocating and managing resources across multiple cloud environments, involving the optimization of task scheduling, resource allocation to minimize makespan, reduce resource costs, and handle the complexity of multi-cloud environments while making optimal scheduling decisions. To overcome this issue. The paper proposes a novel scheduling algorithm, the Advanced Grasshopper Optimization … …Journal of Computer Science, Vol. 21, Issue 10 · 24 Nov 2025 · 2,657 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparison of Multiple Linear Regression and Neural Network Models in Bank Performance Prediction in BotswanaHassan Kablay, Victor GumboBank performance is critical to the banking sector and the economy as a whole. In this study, Multiple Linear Regression (MLR) technique and feed forward Neural Network (NN) are used to predict the performance of 11 banks in Botswana. Return on Assets (RoA) is used as the dependent variable, while management quality, credit risk, liquidity, financial leverage and capital adequacy … …Journal of Mathematics and Statistics, Vol. 17, Issue 1 · 10 Jan 2022 · 6,469 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCost Analysis of K-Out of-n Repairable System with Dependent Failure and Stand by Support Using Kolmogorov's Forward Equations MethodM. Y. HaggagProblem statement: Many authors have studied k-out of-n repairable system with dependent failure and standby support. The question was raised whether the repair and standby units support increase the reliability of the system. Determine the efficiency of repair and standby support on the reliability of the system. Approach: In this study the statistical analysis of k-out of-n repairable system with … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 6,603 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordKey Structural Aspects for Adaptive Facades - Activity Progress from the EU-COST Action TU1403 ‘Structural’ Task GroupChiara Bedon, Dániel Honfi, Marcin Kozłowski et al.Adaptive facades are getting more and more widespread in modern buildings. These facade systems, among many others, need to fulfil the requirements of several structural considerations, such as structural safety, serviceability, durability, robustness and fire safety, being typically defined for standard facades and building enclosures in general. The current paper discusses special structural characteristics which need to be taken into … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 25 Jun 2018 · 13,380 accessesView PDFCite
