Bubble-based stabilized finite element methods for time-dependent convection-diffusion-reaction problems
Şendur, Ali; Neslitürk, Ali İhsan (Wiley, 2016)In this paper, we propose a numerical algorithm for time-dependent convection-diffusion-reaction problems and compare its performance with the well-known numerical methods in the literature. Time discretization is performed ... -
A comparative study on stabilized finite element methods for the convection-diffusion-reaction problems
Şendur, Ali (Hindawi Limited, 2018)The disproportionality in the problem parameters of the convection-diffusion-reaction equation may lead to the formation of layer structures in some parts of the problem domain which are difficult to resolve by the standard ... -
Error estimates for a fully discrete epsilon-uniform finite element method on quasi uniform meshes
Şendur, Ali; Natesan, Srinivasan; Singh, Gautam (2021)In this article, we analyze a fully discrete epsilon-uniformly convergent finite element method for singularly perturbed convection-diffusion-reaction boundary-value problems, on piecewise-uniform meshes. Here, we choose ... -
Error estimates for a fully discrete varepsilon−uniform finite element methodon quasi uniform meshes
Şendur, Ali; Natesan, Srinivasan; Singh, Gautam (2021)In this article, we analyze a fully discrete varepsilon−uniformly convergent finite element method for singularly perturbed convection-diffusion-reaction boundary-value problems, on piecewise-uniform meshes. Here, we choose ... -
Finite difference approximations of multidimensional convection-diffusion-reaction problems with small diffusion on a special grid
Kaya, Adem; Şendur, Ali (Academic Press Inc Elsevier Science, 2015)A numerical scheme for the convection-diffusion-reaction (CDR) problems is studied herein. We propose a finite difference method on a special grid for solving CDR problems particularly designed to treat the most interesting ... -
A note on epidemiologic models: SIR modeling of the COVID-19 with variable coefficients
Çakır, Zafer; Şendur, Ali (Karaganda Üniversitesi-Matematik Bülteni, 2022)The coronavirus disease 2019 (COVID-19) has been responsible for over three million reported cases worldwide. The construction of an appropriate mathematical (epidemiological) model for this disease is a challenging task. ... -
A note on stabilized finite element methods for predator-prey systems
Şendur, Ali (2019)A numerical method that will improve and produce effective results for solving mathematical model for the system of predator-prey interactions which is defined by convection-diffusion-reaction problem is studied herein. ... -
A stabilizing augmented grid for rectangular discretizations of the convection-diffusion-reaction problems
Şendur, Ali (Springer-Verlag Italia Srl, 2018)We propose a numerical method for approximate solution of the convection-diffusion-reaction problems in the case of small diffusion. The method is based on the standard Galerkin finite element method on an extended space ... -
Uzaktan eğitimde kullanılan senkron ve asenkron yöntemlerin lise öğrencilerinin matematik dersindeki tutum, başarı ve motivasyonuna etkisi
Çelik, Mehmet (Alanya Alaaddin Keykubat Üniversitesi / Lisansüstü Eğitim Enstitüsü, 2022)Bu araştırmanın amacı, asenkron (eş zamanlı olmayan) ve senkron (eş zamanlı) yöntemle eğitim uygulanan lise öğrencilerinin matematik dersindeki tutum, başarı ve motivasyonları üzerine olan etkilerini belirlemektir. Araştırmada ...
