Research ArticleOpen accessIn the author namesPiecewise Positivity Preserving Cubic Bezier Interpolation for Estimating Solar Radiation Missing Value in Penang, MalaysiaAzizan Saaban, Mohd Lutfi Zainudin, Mohd Nazari Abu BakarComplete solar radiation data is important in variety of disciplines such as solar radiation development system or solar project which is strongly affected by hourly variation of the solar radiation. However, the available data may contain missing data for several days in the absence of measurement due to several factors such as instrument failure and human errors. In this study, … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 28 Dec 2016 · 7,125 accessesView PDF Cite

Research ArticleOpen accessIn the author namesIntegration of Artificial Neural Network and Expert System for Material Classification of Natural Fibre Reinforced Polymer CompositesBasheer Ahmed Ahmed Ali, Mohd Sapuan Salit, Edi Syams Zainudin, Mohamed OthmanDiversified choice of materials from natural fibre reinforced polymer composites with similar properties complicate the materials selection for engineering products. Implementation of expert system alone makes it difficult to scrutinize the vast selected materials. Hybrid of expert system with neural network technology is desired. Classification of material through neural network under various criteria influences the decision in narrowing down the … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 29 Apr 2015 · 7,438 accessesView PDF Cite

Research ArticleOpen accessIn the author namesBIODEGRADABILITY AND MECHANICAL BEHAVIOUR OF SUGAR PALM STARCH BASED BIOPOLYMERJ. Sahari, S. M. Sapuan, E. S. Zainudin, M. A. MalequeA new Sugar Palm Starch (SPS) based biopolymer was successfully developed using glycerol as plasticizer. The effect of glycerol concentration (viz., 15, 20, 30 and 40 by weight percent) to the mechanical properties of plasticized SPS biopolymer was investigated. From this investigation, it was found that the 30% glycerol concentrated biopolymer showed the highest flexural strength and impact with the … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 10 Nov 2014 · 7,710 accessesView PDF Cite

Research ArticleOpen accessIn the author namesPOLYMER COMPOSITE MANUFACTURING USING A PULTRUSION PROCESS: A REVIEWA. M. Fairuz, S. M. Sapuan, E. S. Zainudin, C. N.A. JaafarPultrusion is the one of technologies to fabricate the polymer composites to be used in many industries such as in aerospace, automotive and construction industries. The high performance pultruded products that are produced by this technique offer high fibre content of at least 70%. In order to produce high quality pultruded profiles, there are variables such as fibre impregnation, resin … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 29 Oct 2014 · 9,664 accessesView PDF Cite
