Research ArticleOpen accessIn the abstractMoisture Content Prediction of Dried Longan Aril from Dielectric Constant Using Multilayer Perceptrons and Support Vector RegressionSanong Amaroek, Nipon Theera-Umpon, Kittichai Wantanajittikul, Sansanee AuephanwiriyakulProblem statement: Estimation of moisture contents of dried food products from their dielectric constants was an important step in moisture measurement systems. The regression models that provide good prediction performance are desirable. Approach: The Multilayer Perceptrons (MLP) and Support Vector Regression (SVR) were applied in this research to predict the moisture contents of dried longan arils from their dielectric constants. … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvolution of Spatial Correlation of Mean Diameter: A Case Study of Trees in Natural Dipterocarp ForestRafida M. Elobaid, Mahendran Shitan, Noor Akma Ibrahim et al.Problem statement: Spatial modeling has many applications in various fields like agriculture, meteorology, forestry and it takes into consideration the spatial correlation structures. In the field of forestry the growth rate, in particular, the diameter of trees is usually an important parameter. The growth rate of trees in a forest is likely to be influenced by various factors like nutrients, … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical and Magnetoresistive studies Nd doped on La-Ba-Mn-O3 Manganites for Low-field Sensor applicationH. Abdullah, S. A. HalimProblem Statement: Electrical and magnetoresistive properties of the Nd doped (La1-xNdx)0.5Ba0.5MnO3 type samples with 0 ≤ x ≤ 1.0 had been prepared using the solid state reaction. These materials are extensively studied by the substitution of rare-earth compound is to understand the nature of transport phenomena in each system. Approach: The samples were calcined at 900°C for 12 h, pelletized … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,663 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTowards a Reference Model of Software Resources QualityKhaled Almakadmeh, Kenza Meridji, Khalid T. Al-SarayrehInternational standards for software product quality classify software resources as a non-functional requirement for software product. Resources requirements based-standards describe required resources requirements related to software and hardware requirements, in which hardware resources requirements specify requirements relevant to hardware environment in which the software will operate. Whereas, software resources requirements specify sizing and timing requirements required by software product. This … …Journal of Computer Science, Vol. 14, Issue 2 · 3 Feb 2018 · 7,811 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimized Local Ternary Patterns: A New Texture Model with Set of Optimal Patterns for Texture AnalysisG. Madasamy Raja, V. SadasivamTexture analysis is one of the important as well as useful tasks in image processing applications. Many texture models have been developed over the past few years and Local Binary Patterns (LBP) is one of the simple and efficient approach among them. A number of extensions to the LBP method have been also presented but the problem remains challenging in … …Journal of Computer Science, Vol. 9, Issue 1 · 22 Jan 2013 · 6,951 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordDynamic Measurement of Copper (II) Ion Adsorption in Activated Carbon Fixed Bed ColumnsTanokkorn Banjonglaiad, Eric Croiset, Peter Silveston et al.Dynamic experiments were carried out on the adsorption of copper (II) ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a heterogeneous model of the activated carbon bed assuming Langmuir adsorption isotherm. The initial concentration of copper (II) ion was 3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,862 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMeasurement of Gas-Phase Mass Transfer Coefficients in a Humidification Column through Random PackingMasoud Khorasani, Morteza Zivdar, Farshad Fashchi Tabrizi et al.Packed columns are an important part of the broad selection of mass and heat transfer equipment. Nowadays, the use of packed columns is increasing, which is because of its lower pressure drop, higher capacity and higher mass transfer in comparison to tray columns. The experiential tests and the hypothetical analysis display that the chemical dehumidification of air by hygroscopic salt … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,028 accessesView PDFCite
