Research ArticleOpen accessIn the abstractComposition Dependent Structural and Thermal Properties of SM2O3 Doped Zinc Fluoroborate GlassesSudha D. Kamath, Akshatha Wagh, M.P. AjithkumarGlasses based on Sm3+ doped zinc fluoroborate have been synthesized and characterized. Formation of glass has been investigated in the 30 ZnF2-20 TeO2-(50-x) B2O3-x Sm2O3 matrix. Fast quenching is required to prevent melt crystallization and adequate heat treatment to diminish thermal stress, which results in an efficient amorphous material. The Differential Scanning Calorimeter (DSC), Scanning Electron Microscopy (SEM), Energy Dispersive … …Energy Research Journal, Vol. 4, Issue 2 · 15 Jul 2014 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractObservation Modeling for Continuous Predicting Global and Diffuse Solar Radiation on Horizontal SurfaceSomporn Hongkong, Singthong PattanasethanonMathematical modeling for continuous prediction of solar energy is inevitable for energy systems. General, existing models are mostly empirical and data dependent. This article has to present a variable model for predicting global and diffuse solar radiation on the horizontal plane. The model considered in this study has applied Hidden Markov Model (HMM) with two observations. The databases were measured … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 23 May 2013 · 6,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractPalm Oil Milling Wastes and Sustainable DevelopmentA.C. Er, Abd. Rahim Md. Nor, Katiman RostamProblem statement: Palm oil milling generates solid wastes, effluent and gaseous emissions. The aim of this study is to assess the progress made in waste management by the Malaysian palm oil milling sector towards the path of sustainable development. Sustainable development is defined as the utilization of renewable resources in harmony with ecological systems. Inclusive in this definition is the … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotostability of Ponceau 2R Doped Thin Film Sol-Gel Silica as Luminescent Solar CollectorS.M. RedaProblem statement: Current researches had shown that the photostability of a luminescent solar collector depend on the method of its preparation and type of using dye. This research therefore aimed at studying the stability of luminescent solar collector prepared by sol-gel spin coating method using Ponceau 2R. Approach: The effect of silica matrix on the photostability and fluorescence properties of … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Temperature and Acid Concentration on Corrosion of Low Carbon Steel in Hydrochloric Acid MediaAnees A. Khadom, Aprael S. Yaro, Abdul Amir H. Kadum et al.Problem statement: The effect of different temperatures and acid concentrations on the corrosion of low carbon steel in hydrochloric acid were addressed in this study. Approach: The effect of temperature was explained by application of Arrhenius equation and transition state theory, while the acid concentration effect was explained using reaction kinetic equations. The combined effect of temperature and acid concentration … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 11,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultistage Development of Müller-Achenbach model for Shape Memory AlloySimin Ataollahi Oshkovr, Nik Abdullah Nik Mohamed, Che Husna Azhari et al.This research focused on the conceptual development of constitutive Müller-Achenbach model and proceeds to construct a model based on phase transition under changing temperature and load for variants of martensite in shape memory alloy CuAlNi (Copper-aluminum-nickel). Problem statement: Motivation of this research is rare information of a variant of martensite phase (M++) and prediction of the shape recovery of shape … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Wear Map for the Sliding and Rotational Wear behavior of ShaftsAl-mahasne Mayas MohammadThis study was an attempt to study the wear calculation method for rotating shaft in the friction couple type shaft-cuff in conditions of oiling in high dusty environment. The size and quantity of abrasive particles that go into the clearance between friction surfaces, definition of the pressure including the load in conjugate that is given by the cuff spring as … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractOscillatory Dynamical Switching System of Bulk FerroelectricsM. N.A. Halif, S. Daud, Junaidah OsmanThis study gives a detailed account of calculation of the bulk ferroelectric (FE) oscillatory dynamical system switching to first and second-order phase transition, respectively. All the formalism is delineated in the framework of Landau free-energy expansion and Landau-Khalatnikov (LK) equation of motion where the effect of external energy may affray FE atoms similar to the spring damped oscillatory system. Here … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,677 accessesView PDFCite
