The Topp-Leone generalized odd log-logistic family of distributions: properties, characterizations and applications
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
A new family of distributions called the Topp-Leone generalized odd log-logistic-G family is introduced and studied. We provide some mathematical properties of the new family including ordinary and incomplete moments, ...
A numerical solution study on singularly perturbed convection-diffusion nonlocal boundary problem
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
This important numerical method is given for the numerical solution of singularly perturbed convection-diffusion nonlocal boundary value problem. First, the behavior of the exact solution is analyzed, which is needed for ...
The mean remaining strength of parallel systems in a stress-strength model based on exponential distribution
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
The mean remaining strength of any coherent system is one of the important characteristics in stress-strength reliability. It shows that the system on the average how long can be safe under the stress. In this paper, we ...
Improved Hermite Hadamard type inequalities for harmonically convex functions via Katugampola fractional integrals
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
In this paper,we proved three new Katugampola fractional Hermite- Hadamard type inequalities for harmonically convex functions by using the left and the right fractional integrals independently. One of our Katugampola frac- ...
Equilibrium and Stability Analysis of Takagi-Sugeno Fuzzy Delayed Cohen-Grossberg Neural Networks
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
This paper carries out an investigation into the problem of the global asymptotic stability of the class of Takagi-Sugeno (T-S) fuzzy delayed Cohen-Grossberg neural networks with discrete time delays. A new sufficient ...
Degree based topological invariants of splitting graph
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
Topological invariants are the graph theoretical tools to the theoretical chemists, that correlates the molecular structure with several chemical reactivity, physical properties or biological activity numerically. A function ...
Investigation of the dependence structure in seismic hazard analysis: an application for Turkey
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
In this study, using the earthquake occurrence data (Richter magnitude is equal to 4 or greater than 4 in the years 1901-2014) of the areas limited by 39.5°-42° N latitudes and 26°-45° E longitudes of North Anatolia and ...
Some Tauberian theorems for weighted means of double integrals
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
Let p(x) and q(y) be nondecreasing continuous functions on [0,∞) such that p(0)=q(0)=0 and p(x),q(y)→∞ as x,y→∞. For a locally integrable function f(x,y) on R₊²=[0,∞)×[0,∞), we denote its double integral by F(x,y)=∫₀^{x} ...
On the evolute offsets of ruled surfaces using the Darboux frame Yıl 2019, Cilt 68, Sayı 2, 1256 - 1264, 01.08.2019
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
In this study, using Darboux frame {T,g,n} of ruled surface ϕ(s,v), the evolute offsets ϕ^{∗}(s,v) with Darboux frame {T^{∗},g^{∗},n^{∗}} of ϕ(s,v) are defined. Characteristic properties of ϕ^{∗}(s,v) as a striction curve, ...
Spectral expansion of Sturm-Liouville problems with eigenvalue-dependent boundary conditions
(Ankara Üniversitesi Fen Fakültesi, 2019-08-01)
In this paper, we consider the operator L generated in L₂(R₊) by the differential expression
l(y)=-y′′+q(x)y,x∈R₊:=[0,∞)
and the boundary condition
((y′(0))/(y(0)))=α₀+α₁λ+α₂λ²,
where q is a complex valued ...
