Research ArticleOpen accessIn the abstractImproved Continuing Losses Estimation Using Initial Loss-Continuing Loss Model for Medium Sized Rural CatchmentsMahbub Ilahee, Monzur Alam ImteazProblem statement: The rainfall based design flood estimation techniques are commonly adopted in hydrological design and require a number of inputs including information on soil loss characteristics. Approach: A conceptual loss model known as the ‘Initial Loss-Continuing Loss (IL-CL) model’ is widely used in Australia. Results: The Initial Loss (IL) occurs at the beginning of the rainfall event, prior to … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Block Method for Special Third Order Ordinary Differential EquationsB. T. Olabode, Y. YusuphA linear multistep method for the direct solution of initial value problems of ordinary differential equations was presented in this article. Collocation approximation method was adopted in the derivation of the scheme and then the scheme was applied as simultaneous integrator to special third order initial value problem of ordinary differential equations. The new block method possessed the desirable feature … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,707 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multiderivative Collocation Method for 5th Order Ordinary Differential EquationsS. J. Kayode, D. O. AwoyemiProblem statement: The conventional methods of solving higher order differential equations have been by reducing them to systems of first order equations. This approach is cumbersome and increases computational time. Approach: To address this problem, a numerical algorithm for direct solution of 5th order initial value problems in ordinary differential equations (odes), using power series as basis function, is proposed … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 8,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEW APPROACH TO SOLVE HYBRID FUZZY DIFFERENTIAL EQUATIONSaveetha Natesan, Nirmala Venkatachalem, S. Chenthur PandianThis study presents solution for the first order hybrid fuzzy differential equation by Runge-Kutta method of order two with new parameters and Harmonic mean of ki’s which are used in the main formula in order to increase the order of accuracy of the solution. This method is discussed in detail followed by a complete error analysis. The accuracy and efficiency … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 1 Jul 2013 · 6,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldThe poultry industry is one of the largest and fastest growing sectors of livestock production in the world. The estimated 2010 world flock was over 18 billion birds with a yearly manure output of 22 million tonnes. Storage and disposal of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 9,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Solution of Higher Order Ordinary Differential Equations by Direct Block CodeN. Waeleh, Z. A. Majid, F. Ismail, M. SuleimanProblem statement: This study is concerned with the development of a code based on 2-point block method for solving higher order Initial Value Problems (IVPs) of Ordinary Differential Equations (ODEs) directly. Approach: The block method was developed based on numerical integration and using interpolation approach which is similarly as Adams Moulton type. Furthermore, the proposed method is derived in order … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 3 Feb 2012 · 8,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrowave Assisted Bioethanol Production from Sago Starch by Co-Culturing of Ragi Tapai and Saccharomyces CerevisiaeN. Saifuddin, Refal HussainProblem statement: Environmental issues such as global warming and recent events throughout the world, including the shortage of petroleum crude oil, the sharp increase in the cost of oil and the political instability of some crude oil producing countries, have demonstrated the vulnerability of the present sources for liquid fuel. These situations have created great demand for ethanol from fermentation … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Exploration Using a Three-Axis Tactile Sensing InformationS. C. Abdullah, Jiro Wada, Masahiro Ohka, Hanafiah YussofProblem statement: To advance the robust object recognition of robots, we present an algorithm for object exploration based on three-axis tactile data that is necessary and sufficient for the evaluation of contact phenomena. Approach: The object surface contour is acquired by controlling the finger position so that the normal force, measured by optical three-axis tactile sensors, remains constant as two … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,313 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress-Strain Analysis of Abdominal Aortic Wall: A Case of 3D Geometry SimulationP. Khamdaengyodtai, P. Sakulchangsatjatai, P. TerdtoonProblem statement: This study analyzed stress-strain of abdominal aortic wall in 3D geometry simulation. Abdominal aorta is a portion of the aorta vessel in the abdomen which many cardiovascular diseases often occur. Approach: Abdominal aortic wall was considered as 1 layers-3 dimensional cylindrical geometry and homogeneous, incompressible and anisotropic material. Deformation of aortic wall was elastic deformation. Numerical method was … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,406 accessesView PDFCite
