AN EXAMINATION OF THE CONDITION UNDER WHICH A CONCHOIDAL SURFACE IS A BONNET SURFACE IN THE EUCLIDEAN 3-SPACE
(Univ Nis, 2021)
In this study, we examine the condition of the conchoidal surface to be a Bonnet surface in Euclidean 3-space. Especially, we consider the Bonnet conchoidal surfaces which admit an infinite number of isometrics. In addition, ...
On a variational problem due to the B-Darboux frame in Euclidean 3-space
(Wiley, 2021)
In this paper, we introduce a new frame which is called the B-Darboux frame on a surface in Euclidean 3-space. We know that the parallel transport frame is derived from the Frenet frame along a space curve on a surface. ...
Zonal geomagnetic indices estimation of the two super geomagnetic activities of 2015 with the artificial neural networks
(Elsevier Sci Ltd, 2021)
This paper discusses the estimation of zonal geomagnetic indices of two super geomagnetic activities of 2015 in the 24th solar cycle. It estimates the zonal geomagnetic indices (Dst, ap, AE) of 17 March and 22 June 2015 ...
Determination of the Some Results for Coupled Fixed Point Theory in C*- Algebra Valued Metric Spaces
(Indonesian Mathematical Soc, 2020)
In the present paper, we introduce the coupled fixed point theorem in C*-algebra valued metric spaces. We get a C*-algebra valued metric space which get values in noncomutative operators. We demonstrate existance and ...
Representation of integers by k-generalized Fibonacci sequences and applications in cryptography
(World Scientific Publ Co Pte Ltd, 2021)
The aim of this paper is to construct a relation between tribonacci numbers and generalized tribonacci numbers. Besides, certain conditions are obtained to generalize the representation of a positive integer N which is ...
Analysis of the first four moderate geomagnetic storms of the year 2015
(Springer Heidelberg, 2021)
This essay investigates the first four moderate geomagnetic activities (the 04 January storm, the 07 January storm, the 17 February storm, and the 24 February storm) of 2015 in the 24th solar cycle. The essay attempts to ...
Hermite-Hadamard type inequalities for m-convex and (alpha, m)-convex functions
(Springer, 2020)
In this paper, some new inequalities of the Hermite-Hadamard type for the classes of functions whose derivatives' absolute values arem-convex and(alpha,m)-convex are obtained. The results obtained in this work extend and ...
Integral inequalities of Hermite-Hadamard type for exponentially subadditive functions
(Amer Inst Mathematical Sciences-Aims, 2020)
In this paper, we introduce a new class of functions, which is called exponentially subadditive functions. We establish Hermite-Hadamard inequalities via exponentially subadditive functions. We also give some related ...
Practical stability analysis of perturbed fuzzy control system related to unperturbed fuzzy control system
(Scientific Technical Research Council Turkey-Tubitak, 2021)
The behavior of solutions of a perturbed fuzzy control system with respect to an original unperturbed fuzzy control system is investigated. Notions of practical stability, asymptotic stability and instability are introduced. ...
THE RELATIVELY OSCULATING DEVELOPABLE SURFACES OF A SURFACE ALONG A DIRECTION CURVE
(Ankara Univ, Fac Sci, 2020)
We construct a developable surface tangent to a surface along a curve on the surface. We call this surface as relatively osculating developable surface. We choose the curve as the tangent normal direction curve on which ...
