Algorithmic approach of cordial labeling on Cartesian product between balanced bipartite graph and path
(Ankara Üniversitesi Fen Fakültesi, 20190801)Cordial labeling is one of the useful labeling in the realm of graph labeling. For the graph G=(V,E) vertex set V is label by {0,1}, where labeling of edge set E calculated by absolute difference between the end vertices ... 
Fuzzy Markov chains modeling of aggregation processes
(Ankara Üniversitesi Fen Fakültesi, 20190801)In this paper, the fuzzy Markov chain method is proposed as a new discrete solution of a population balance equation for an aggregation process. In order to validate the proposed method, analytical solution of an aggregation ...

(Ankara Üniversitesi Fen Fakültesi, 20190801)Koyuncu and Kadilar <cite>kk.2009</cite> introduced a family of estimators under simple random sampling. In this article; we adapt these estimators for ranked set sampling. Further, we suggest a regressiontype estimator ... 
A new subclass of uniformly spirallike functions with fixed coefficients
(Ankara Üniversitesi Fen Fakültesi, 20190801)In this paper a new subclass of uniformly spirallike functions is defined and several properties like coefficient estimate, closure theorems, distortion theorems, radii of starlikeness and convexity are studied. 
Approximation by Nörlund and Riesz means in weighted Lebesgue space with variable exponent
