  • Numerical study of heat and mass transfer in magneto hydrodynamic flow past a vertical plate with constant injection and heat flux 
    Ambethkar, V. (Selcuk University Research Center of Applied Mathematics, 2010)
    We have studied heat and mass transfer in an unsteady MHD flow of an incompressible, electrically conducting, and viscous fluid. It is considered that the influence of the uniform magnetic field normal to the flow. Numerical ...
  • On canal surfaces in E3 
    Öztürk, G.; Bulca, B.; Bayram, B. K.; Arslan, K. (Selcuk University Research Center of Applied Mathematics, 2010)
    In this paper we deal with the geometric properties of canal surfaces in E. Further, the first and second fundamental form of canal surfaces are presented. By the use of the second fundamental form, the Gaussian and mean ...
  • An application of determining the best tax ratios by goal programming 
    Şahiner, Ahmet; Akın, H. Seda; Türen, Bahri (Selcuk University Research Center of Applied Mathematics, 2010)
    Numerous procedures are used to solve multiple criteria decision-making problems. Among these the most frequently used procedure is goal programming, which is also the selected procedure for this study. It will be used to ...
  • Lie symmetries of the black-scholes equation 
    Polat, Refet (Selcuk University Research Center of Applied Mathematics, 2010)
    In this paper symmetry expansions for Black-Scholes equation are studied. Differently then the other studies in the literature for Black-Scholes equation, we expanded the equation into a parametric form by adding a coefficient ...
  • A Bayesian approach to a process control problem 
    Sunar, Özlem; Ergün, Gül (Selcuk University Research Center of Applied Mathematics, 2010)
    Classical process control methods are not suitable when the number of observations is low. In this study, a Bayesian scheme is considered for a statistical process control problem where process mean is unknown and has jumps ...
  • Cyclic codes over some finite rings 
    Özen, Mehmet; Güzeltepe, Murat (Selcuk University Research Center of Applied Mathematics, 2010)
    In this paper cyclic codes are studied with respect to the Mannheim metric over some finite rings by using Gaussian integers and the decoding procedure for these codes is given.
  • Average edge-distance in graphs 
    Balcı, Mehmet Ali; Dündar, Pınar (Selcuk University Research Center of Applied Mathematics, 2010)
    The average edge-distance of a connected graph G is the average of the distance between all pairs of edges of G. In this work we give the average edge-distance of a graph, a new vulnerability measure. We also find sub and ...
  • Oscillation results of higher order nonlinear neutral delay differential equations 
    Yıldız, M. K.; Öcalan, Ö. (Selcuk University Research Center of Applied Mathematics, 2010)
    In this paper, we shall consider higher order nonlinear neutral delay differential equation of the type[x(t)+p(t)x(?(t))]???+q(t)[x(?(t))]^{?}=0,t?t?, n?N,where p,q?C([t?,?),[0,?)), ?,?? C([t?,?),R), ?(t)<t,lim_{t??}?(t)=?, ...
  • Exact travelling solutions for the generalized (1+1) dimensional and the generalized (2+1) dimensional Ito equations by G'/G-expansion method 
    Abdollahzadeh, M.; Ganji, D. D.; Davodi, A. G.; Barzegar, M. (Selcuk University Research Center of Applied Mathematics, 2010)
    In this paper, we establish exact solutions for some nonlinear partial differential integral equations (PDIE). The (((G?)/G))-expansion method was used to construct travelling wave solutions of the generalized (1+1) ...
  • A new application of modified differential transformation method for modelling the pollution of a system of lakes 
    Merdan, Mehmet (Selcuk University Research Center of Applied Mathematics, 2010)
    In this papers, a new application of modified differential transformation method (MDTM) is implemented to solve analytically systems of nonlinear ordinary differential equations such as modelling the pollution of a system ...
  • Unsteady flow of micropolar fluid through a circular pipe under a transverse magnetic field with suction/injection 
    Murthy, J. V. Ramana; Bahali, N. K.; Srinivasacharya, D. (Selcuk University Research Center of Applied Mathematics, 2010)
    In this paper, we consider the unsteady flow of an incompressible electrically conducting micropolar fluid through a circular porous pipe subjected to periodic suction/injection at the walls of the tube and in the presence ...
  • Population dynamical model for AIDS patients of a particular area 
    Rahman, Shamsur; Rahman, Atiqur (Selcuk University Research Center of Applied Mathematics, 2010)
    This is an attempt to translate the problem of AIDS patients into a mathematical problem, thereafter interpreting the solution in the language of real world. Here we proposed HIV/AIDS among the peoples as a resultant ...
