Optimal management of a prey-predator system in a polluted environment with effort shared between pollution reduction and harvesting
(Işık University Press, 2024-04)
This paper is concerned with the optimal management of a prey-predator system in a polluted environment with effort allocated between pollution reduction and prey harvesting. The growth rates of species and, consequently, ...
Solving inverse partial differential equations problems by using teaching learning based optimization algorithm
(Işık University Press, 2024-04)
In this paper, a numerical approach is combined with teaching learning based optimization algorithm (TLBO) to solve problems of inverse partial differential equations. The most important point in the way we have presented ...
Fitted computational method for convection dominated diffusion equations with shift arguments
(Işık University Press, 2024-04)
A time dependent singularly perturbed convection diffusion equation involving shift parameters are considered. The terms containing the shifts are treated using Taylor series approximation up to second order terms. Classical ...
Generalized q-difference equation for the generalized q-operator r?s(Dq) and its applications in q-integrals
(Işık University Press, 2024-04)
In 2014, Fang [12] discovered a general q-exponential operator identity by solving a q-difference equation. Fang [12] developed some generalizations of q-integrals using this q-difference equation. Reshem and Saad [20] ...
Algebraic sum and algebraic product of spherical neutrosophic sets
(Işık University Press, 2024-04)
The Spherical Neutrosophic Set is a generalization of Spherical Fuzzy Set. In this paper, we define Algebraic sum and Algebraic product of spherical neutrosophic sets (SNSs) and investigate their desirable properties. ...
Connecting statistics, probability, algebra and discrete mathematics
(Işık University Press, 2024-04)
In this paper, we connect four different branches of Mathematics: Statistics, Probability, Algebra and Discrete Mathematics with the objective of introducing new results on Markov chains and evolution algebras obtained by ...
Graph invariants based on distance between edges and double graphs
(Işık University Press, 2024-04)
Topological indices are numerical parameters of graph which characterize its topology and are invariant under graph isomorphism. They are applied in theoretical chemistry for the design of chemical compounds with certain ...
On kernel distribution function estimation near end points
(Işık University Press, 2024-04)
Under that so-called boundary problem on kernel cumulative distribution function estimation, the main objective of this paper is to introduce and investigate the properties of our new estimator in order to improve the ...
Geodetic parameters in tree derived architectures
(Işık University Press, 2024-04)
A geodetic cover of a graph G refers to a subset of vertices of G that covers all the vertices of G using the shortest paths between the vertices in the set and the cardinality of a minimum geodetic cover is the geodetic ...
The impact of the COVID-19 pandemic on online grocery supply chain management: a case study in Istanbul
(Gazi Üniversitesi, 2024-03)
The COVID-19 pandemic has already crippled normal life all over the world. Its negative impact not only changed the human health system tragically but also disrupted the global economic system. One negative result was ended ...
