Domination and efficient domination in cubic and quartic Cayley graphs on abelian groups
Çalışkan, Cafer; Miklavic, Stefko; Özkan, Sibel (Discrete Applied Mathematics, 2019)In this paper, we characterise cubic and quartic Cayley graphs on abelian groups that admit an efficient dominating set, and then we give domination numbers, even when they do not have an efficient dominating set, when it ... -
Effect of vitamin d levels on lipid, glucose, vitamin b12 and c-reactive protein in acute ischemic stroke
Kozacı, Nalan; Çalışkan, Cafer; Avcı, Mustafa; Çalışkan, Gülsüm; Uysal, İlhan (Annals of Medical Research, 2020)Aim: Stroke ranks second among the causes of death world wideand related disability and death rates are high.

Efficient domination in Cayley graphs of generalized dihedral groups
Çalışkan, Cafer; Miclavic, Stefko; Özkan, Sibel; Sparl, Primoz (Discussiones Mathematicae Graph Theory, 2020)An independent subset D of the vertex set V of the graph is an effcient dominating set for this graph if each vertex v in V \ D has precisely one neighbour in D. In this article, we classify the connected cubic Cayley ... -
A hybrid movie recommender system and rating prediction model
Çalışkan, Cafer; Sanwal, Muhammad (International Journal of Information Technology and Applied Sciences, 2021-07-01)In the current era, a rapid increase in data volume produces redundant information on the internet. This predicts the appropriate items for users a great challenge in information systems. As a result, recommender systems ... -
