On the existence of solution for an inverse problem
(Işık University Press, 2013)We consider a boundary detection problem. We present physical motivations. We formulate the problem as a shape optimization problem by introducing the Neumann condition of the accessible part in a cost functional to be ... -
Haar basis method to solve some inverse problems for two-dimensional parabolic and hyperbolic equations
(Işık University Press, 2013)A numerical method consists of combining Haar basis method and Tikhonov regularization method. We apply the method to solve some inverse problems for twodimensional parabolic and hyperbolic equations using noisy data. In ... -

(Işık University Press, 2013)In the present paper, we have proved some convergence properties of a sequence of elements in a partial cone metric space and thereby we have established some fixed point theorems on it. -
Interaction between selection and segregation ratios with redefined concept of fitness differentials
(Işık University Press, 2013-01-11)Taking into account the redefined concept of fitness differentials among the genotypes, natures of equilibria of models of differential selection in the two sexes under random mating with Mendelian segregation as well as ... -
Series solution of epidemic model
(Işık University Press, 2012-10-17)The present paper is concerned with the approximate analytic series solution of the epidemic model. In place of the traditional numerical, perturbation or asymtotic methods, Laplace-Adomian decomposition method (LADM) is ... -
Asymptotic expansions for the ergodic moments of a semi-markovian random walk with a generalized delaying barrier
(Işık University Press, 2012)In this study, a semi-Markovian random walk process (X(t)) with a generalized delaying barrier is considered and the ergodic theorem for this process is proved under some weak conditions. Then, the exact expressions and ... -
Energy preserving integratıon of KDV-KDV systems
(Işık University Press, 2012-07-01)Coupled Korteweg de Vries (KdV) equations in Hamiltonian form are integrated by the energy preserving average vector field (AVF) method. Numerical results confirm long term preservation of the energy and the quadratic ... -
A numerical solution of an inverse parabolic problem
