Analysing of Tuberculosis in Turkey through SIR, SEIR and BSEIR Mathematical Models
Uçakan, Yasin; Gülen, Seda; Köklü, Kevser (Taylor and Francis Ltd., 2021)Since mathematical models play a key role in investigating the dynamics of infectious diseases, many mathematical models for these diseases are developed. In this paper, it is aimed to determine the dynamics of Tuberculosis ... -
An efficient hybrid method based on cubic B-spline and fourth-order compact finite difference for solving nonlinear advection-diffusion-reaction equations
Gülen, Seda (Springer, 2023)This paper proposes an efficient hybrid numerical method to obtain approximate solutions of nonlinear advection-diffusion-reaction (ADR) equations arising in real-world phenomena. The proposed method is based on finite ... -
A Fréchet derivative-based novel approach to option pricing models in illiquid markets
Gülen, Seda; Sarı, M. (John Wiley and Sons Ltd, 2022)Nonlinear option pricing models have been increasingly concerning in financial industries since they build more accurate values by regarding more realistic assumptions such as transaction cost, market liquidity, or uncertain ... -
The impact of wheat bran and molasses addition to caramba mix silage on feed value and in vitro organic matter digestibility
Gülen, Seda (Elsevier B.V., 2023)Background: The fermentation process in silage is an inherently uncontrolled process that results in significant nutritional losses. Supplementing silage with different additives may boost nutrient and energy recovery ... -
INVESTIGATION OF BOTANICAL COMPOSITION, FEED VALUE, ORGANIC MATTER DIGESTIBILITY AND NET ENERGY LACTATION OF GRASS SILAGE AT EARLY MATURITY STAGE BY IN VIVO AND IN VITRO METHODS
Gülen, Seda (Corvinus Univ Budapest, 2022)This study was carried out to determine botanical composition, nutritive value, organic matter digestibility (OMD) and net energy lactation (NEL) of grass ensiled at early (early maturity, first cut) stage of maturity. In ... -
A new approach for the black-scholes model with linear and nonlinear volatilities
Gülen, Seda; Popescu, C.; Sarı, M. (MDPI AG, 2019)Since financial engineering problems are of great importance in the academic community, effective methods are still needed to analyze these models. Therefore, this article focuses mainly on capturing the discrete behavior ... -
A novel hybrid method based cubic B-spline for one-dimensional Stefan problem with moving PCM, size-dependent thermal conductivity and periodic boundary condition
Gülen, Seda (Springer Heidelberg, 2022)Phase change materials (PCM) are substances that release and absorb sufficient energy at phase transition to provide useful heat or cooling. Stefan problems including PCM have many applications in science and engineering. ... -
Valuation of the American put option as a free boundary problem through a high-order difference scheme
Sarı, Murat; Gülen, Seda (De Gruyter Open Ltd, 2021)Valuation of the American options encountered commonly in finance is quite difficult due to the possibility of early exercise alternatives. Since an exact solution for the American options does not exist, effective numerical ...
