Research ArticleOpen accessEvery word in the titleIntegration 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 · 7,433 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSelecting Natural Fibers for Bio-Based Materials with Conflicting CriteriaFaris M. AL-Oqla, Mohd Sapuan Salit, Mohamad Ridzwan Ishak, Nuraini Abdul AzizProper material selection enhances both desired physical and meta-physical properties of the end user products. Due to the growing awareness of the environmental issues as well as the industrial sustainability, the Natural Fiber Composites (NFCs) have recently emphasized to be implemented in various industrial applications. The final product features of such composites depend on the integrated characteristics of both matrix … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 16 Mar 2015 · 8,760 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Natural Water with Cow Dung and Agricultural Waste Ratio on Biogas Production from Anaerobic Co-DigestionNaponKeanoi, KanokornHussaro, Sombat TeekasapGlobal warming caused by energy generation from fossil fuel has accelerated the deployment of renewable fuels such as biogas. In this study, batch fermentation (5L) was studied to observe the effect of natural water, cow dung, rice straw and water hyacinth ratio on the biogas and methane production at ambient temperature (31°C), 7.1-7.4 of pH for 52 days. The five … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 22 Jan 2014 · 8,508 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleStatus of Soil Microbial Population, Enzymatic Activity and Biomass of Selected Natural, Secondary and Rehabilitated ForestsK. S. Daljit Singh, A. Arifin, O. Radziah et al.Substantial clearance of forests and conversion of forest into various land use types contribute to deterioration of soil fertility and associated nutrients loss. Soils from natural and rehabilitated forest in Chikus Forest Reserve and also enrichment planting forest and secondary forest of Tapah Hill Forest Reserve, Perak, Malaysia were selected in order to assess the influence of land use change … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,803 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNatural Radioactivity at an Uraniferous SiteClaudio de Carvalho Conti, Esau Francisco Sena Santos, Isabel Cristina Poquet SalinasThe aim of this study is to evaluate the soil composition, the radioactive isotopes concentration and the outdoor air Kerma in the region of the Uraniferous Province of Lagoa Real, Bahia State, located at northeast of Brazil. It has used data from an airborne gamma-ray survey previously carried out in the region, namely Projeto Sao Timoteo and computer simulations of … …Energy Research Journal, Vol. 3, Issue 1 · 14 Feb 2013 · 7,456 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,298 accessesView PDFCite
