Some fixed point results via auxiliary functions on orthogonal metric spaces and application to homotopy
(Amer Inst Mathematical Sciences-Aims, 2022)
In 2017, the concepts of orthogonal set and orthogonal metric spaces are presented. And an extension of Banach fixed point theorem is proved in this type metric spaces. Further in 2019, on orthogonal metric spaces, some ...
Bi-periodic incomplete Horadam numbers
(Tubitak Scientific & Technological Research Council Turkey, 2023)
In this paper, we introduce bi-periodic incomplete Horadam numbers as a natural generalization of incomplete Horadam numbers. We study their basic properties and provide recurrence relations. In particular, we derive the ...
Mannheim Offsets of Ruled Surfaces under the 1-Parameter Motions
(Soc Paranaense Matematica, 2022)
In this study, the situation of Mannheim offsets of ruled surfaces under the 1-parameter motions is investigated. Firstly, relationships between geodesic Frenet trihedrons of Mannheim offsets of ruled surfaces are obtained ...
A Novel Binary Emperor Penguin Optimizer for Feature Selection Tasks
(Tech Science Press, 2022)
Nowadays, due to the increase in information resources, the number of parameters and complexity of feature vectors increases. Optimization methods offer more practical solutions instead of exact solutions for the solution ...

Molecular structure, spectroscopic and DFT studies of 2-(4 ethoxyphenyl) isoindoline-1,3-dione
(Natl Inst Science Communication-Niscair, 2021)
2-(4-Ethoxyphenyl)isoindoline-1,3-dione molecule has been characterized by experimental FT-IR and UV-visible spectroscopic methods. Density factional theory calculations of the molecular structure and vibrational spectra ...
Use of Extreme Low Temperatures Against Callosobruchus chinensis L. (Coleoptera: Chrysomelidae) in Storage Management
(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2022)
This study was carried out to determine the effect of extreme low temperatures on different biological stages of Callosobruchus chinensis L. (Coleoptera: Chrysomelidae). Different extreme low temperatures were tested for ...
Some Identities of Harmonic and Hyperharmonic Fibonacci Numbers
(Gazi Univ, 2021)
This paper is concerned with the combinatorial identities of the harmonic and the hyperharmonic Fibonacci numbers. By using the symmetric algorithm, we get some identities which improve the usual results and generalize ...
Experimental and statistical investigation of the machining performance of wave form end mills on AISI 316L stainless steel
(Gazi Univ, Fac Engineering Architecture, 2021)
Wave form end mills with variable rake and helix angles are new in the machining industry, and limited information is available on their machining performance. In this study, the machining performance of wave form end mills ...
