ORIGINAL_ARTICLE EFFECTS OF MAGNETIC FIELD ON THE RED CELL ON NUTRITIONAL TRANSPORT IN CAPILLARY-TISSUE EXCHANGE SYSTEM A mathematical model for nutritional transport in capillary tissues exchange system in thepresence of magnetic field has been studied. In this case, the cell is deformed. Due to concentrationgradients, the dissolved nutrient in substrate diffuses into surrounding tissue. Theanalytical method is based on perturbation technique while the numerical simulation is basedon finite difference scheme. Results concerning the concentration of dissolved nutrients, diffusiveflux, normal component of velocity and skin friction coefficient, indicate that the presenceof magnetic field influences the flow field considerably.   http://ijm2c.iauctb.ac.ir/article_521845_32491d866cf698c454a190043776c94c.pdf 2014-03-21 1 15 Capillary-Tissue Exchange magnetic field Slip Velocity nutrients Diffusive Flux Nirmala P Ratchagar 1 India Professor Department of Mathematics Annamalai University Chidambaram Tamilnadu India AUTHOR Vijaya Kumar 2 Assistant Professor Mathematics Section FEAT Annamalai University Chidambaram Tamilnadu India AUTHOR

ORIGINAL_ARTICLE NUMERICAL SOLUTIONS OF SECOND ORDER BOUNDARY VALUE PROBLEM BY USING HYPERBOLIC UNIFORM B-SPLINES OF ORDER 4 In this paper, using the hyperbolic uniform spline of order 4 we develop the classes of methods for the numerical solution of second order boundary value problems (2VBP) with Dirichlet, Neumann and Cauchy types boundary conditions. The second derivativeis approximated by the three-point central difference scheme. The approximate results, obtained by the proposed method, confirm theconvergence of numerical solutions. Numerical results are given to illustrate the efficiency of our methods.   http://ijm2c.iauctb.ac.ir/article_521847_45a7c9532fe79eb0f3649c9d791c59aa.pdf 2014-03-21 25 36 Boundary Value Problem interpolation hyperbolic uniform spline Abdellah Lamnii 1 Faculty of Science and Technology, University Hassan first, Settat, Morocco Morocco AUTHOR
ORIGINAL_ARTICLE SOLVING SINGULAR ODES IN UNBOUNDED DOMAINS WITH SINC-COLLOCATION METHOD Spectral approximations for ODEs in unbounded domains have only received limited attention. In many applicable problems, singular initial value problems arise. In solving these problems, most of numerical methods have difficulties and often could not pass the singular point successfully. In this paper, we apply the sinc-collocation method for solving singular initial value problems. The ability of the sinc-collocation method in overcoming the singular points difficulties makes it an efficient method in dealing with these equations. We use numerical examples to highlight efficiency of sinc-collocation method in problems with singularity in equations.   http://ijm2c.iauctb.ac.ir/article_521848_a67201140145f8814ff55c65a9752cd8.pdf 2014-03-21 37 44 Sinc-collocation method Singular Initial value problem linear problems Nonlinear problems H.

ORIGINAL_ARTICLE SENSITIVITY ANALYSIS OF EFFICIENT AND INEFFICIENT UNITS IN INTEGER-VALUED DATA ENVELOPMENT ANALYSIS One of the issues in Data Envelopment Analysis (DEA) is sensitivity and stability region of the speci c decision making unit (DMU), included ecient and inecient DMUs. In sensitivity analysis of ecient DMUs,the largest region should be found namely stability region thatdata variations are only for ecient DMU under evaluation and the data for the remainingDMUs are assumed xed. Also ecient DMU under evaluation remains ecient with thesevariations. In sensitivity analysis of inecient DMU, it can obtain an eciency score whichis de ned by the manager. In traditional DEA we assume that all inputs and outputs are realamounts and consider continuous inputs and outputs. Although,there are some applicationsin which one or more inputs and/or outputs can only take integer quantities. In this paper,we obtain the stability region for ecient DMU and the eciency score of a speci c inecientDMU changes to a de ned eciency score by management, with integer data http://ijm2c.iauctb.ac.ir/article_521849_a47d6c1d22bd1b3d0bde22e6c575b355.pdf 2014-03-21 45 53 Data Envelopment Analysis (DEA),sensitivity, Integer Data EnvelopmentAnalysis(IDEA) stability region decision making unit Shokoofeh Banihashemi 1 Faculty of Economics, Allameh Tabatabai University Iran, Islamic Republic of Academic member of Department of Mathematics, Computer and Statistics AUTHOR Ghasem Tohidi 2 Central Branch, Islamic Azad University Iran, Islamic Republic of Academic member Department of Mathematics AUTHOR Masoud Sanei 3 Central Branch, Islamic Azad University Iran, Islamic Republic of Academic member Department of Mathematics AUTHOR
ORIGINAL_ARTICLE A SIXTH ORDER METHOD FOR SOLVING NONLINEAR EQUATIONS In this paper, we present a new iterative method with order of convergence eighth for solving nonlinear equations. Periteration this method requires three evaluations of the function and one evaluation of its first derivative. A general error analysis providing the eighth order of convergence is given.

ORIGINAL_ARTICLE AN ADAPTIVE WAVELET SOLUTION TO GENERALIZED STOKES PROBLEM In this paper we will present an adaptive wavelet scheme to solvethe generalized Stokes problem. Using divergence free wavelets, theproblem is transformed into an equivalent matrix vector system, thatleads to a positive definite system of reduced size for thevelocity. This system is solved iteratively, where the applicationof the infinite stiffness matrix, that is sufficiently compressible,is replaced by an adaptive approximation. Finally we prove that thisadaptive method has optimal computational complexity, that is itrecovers an approximate solution with desired accuracy at acomputational expense that stays proportional to the number of termsin a corresponding wavelet-best N-term approximation. http://ijm2c.iauctb.ac.ir/article_521851_07d7eb19aed6b575c6b5b8caab6b0bb0.pdf 2014-03-21 61 75 Wavelet basis Riesz basis Adaptive solution N-term approximation Galerkin approximation Hassan Jamali 1 Vali-e-Asr University of Rafsanjan Iran, Islamic Republic of AUTHOR Ataollah Askari Hemmat 2 Shahid Bahonar University of Kerman Iran, Islamic Republic of AUTHOR
