(Işık University Press, 2020)
Our purpose in this paper is to study certain basic properties of k-Bessel function, introduced by Gehlot [Nonl. Anal. Diff. Eq., 2(2)(2014), 61-67]. In this regard, we obtain addition theorem, expansions formula, integral ...
• #### Adriatic indices and sanskruti index envisage of carbon nanocone ﻿

In [17, 18], D. Vukicevic notified the 148 discrete adriatic indices. They were analyzed on the testing sets provided by the International Academy of Mathematical Chemistry and it had been shown that they have good presaging ...
• #### Algebraic construction of semi bent function via known power function ﻿

(Işık University Press, 2021)
The study of semi bent functions (2- plateaued Boolean function) has attracted the attention of many researchers due to their cryptographic and combinatorial properties. In this paper, we have given the algebraic construction ...

(Işık University Press, 2015)
This paper studies the problem of minimizing a linear objective function subject to max-T fuzzy relation equation constraints where T is a special class of pseudot-norms. Some sufficient conditions are presented for ...
• #### An algorithmic approach to equitable edge chromatic number of graphs ﻿

(Işık University Press, 2019)
The equitable edge chromatic number is the minimum number of colors required to color the edges of graph G, for which G has a proper edge coloring and if the number of edges in any two color classes differ by at most one. ...
• #### Algorithmic complexity of isolate secure domination in graphs ﻿

(Işık University Press, 2021)
A dominating set S is an Isolate Dominating Set (IDS) if the induced subgraph G[S] has at least one isolated vertex. In this paper, we initiate the study of new domination parameter called, isolate secure domination. An ...
• #### Almost periodic positive solutions for a delayed nonlinear density dependent mortality Nicholson’s blowflies model on time scales ﻿

In this paper we discuss a nonlinear density dependent mortality Nicholson’s blowflies equation with multiple pairs of time varying delays. By contraction mapping theorem, we derived the necessary conditions for the existence ...
• #### Almost unbiased ridge estimator in the zero-inated Poisson regression model ﻿

(Işık University Press, 2022)
The zero-inflated Poisson regression (ZIP) model is a very popular model for count data that have extra zeros. In some situations, the count data are correlated and so multicollinearity exists among the explanatory variables. ...
