Effects of sinusoidal and non-sinusoidal temperature modulation in a triple diffusive convection
(Işık University Press, 2021)The Triple Diffusive convection with time-dependent sinusoidal (cosine) and non-sinusoidal (square and triangular) temperature modulation is studied using linear and non-linear analysis. The expression for Rayleigh number ... -
Group methods for second order delay differentşal equations
(Işık University Press, 2021)In this research paper, we obtain the equivalent symmetries of non-homogeneous second order delay differential equations with variable coefficients. Group methods have been used to do this. The approach followed by us to ... -
Some new Hermite–Hadamard integral inequalities in multiplicative calculus
(Işık University Press, 2021)In this paper, we tend to establish some new Hermite–Hadamard type integral inequalities for multiplicatively convex function on coordinates and for product of two multiplicatively convex functions on coordinates. -
On generalization of explicit expressions of some hybrid Tricomi functions
(Işık University Press, 2021)In this paper, a general quadruple series identity is established. By using general quadruple series identity, a Laurent type hypergeometric generating relation is derived. Certain explicit expressions of some hybrid special ... -
Computing ve topological indices of Tickysim SpiNNaker Model
(Işık University Press, 2021)Topological parameters are employed to calculate the biological activity, thermodynamic properties, chemical reactivity and physical features of different structures, since various studies show a strong bond between the ... -
Disjunctive total domination in some graphs derived from the subdivision graph
(Işık University Press, 2021)For a set S ⊆ V (G), if every vertex has a neighbor in S or has at least two vertices in S at distance two from it, then the set S is a disjunctive total dominating set of G. The minimum cardinality of such a set is equal ... -

The non-homogeneous of semi-linear parabolic equation with integral conditions
(Işık University Press, 2021)In this paper we introduce another method to establish finite time blow-up. This method, introduce by Levine–Payne in the papers [3], [4] and is due to Levine (1973), uses the concavity of an auxiliary function I(t). -
Coeffıcient estimates for bi-univalent ma-minda type functions associated with q-derivative
(Işık University Press, 2021)In this article, we consider a new subclasses of analytic and bi-univalent functions associated with q-derivative in the open unit disk. We obtain coefficient bounds for the Taylor-Maclaurin coefficients |a2| and |a3| of ... -
An extension theorem on degree of approximation of fourier series by (E, q)B−mean
