A theoretical study on resistance of electrolytic solution: Measurement of electrolytic conductivity
Results in Physics, 2019 We propose a theoretical approach to determine the conductivity of electrolytic solution using sine waveform voltage as a triggering signal. The approach is based on the acquisition of the complex impedance in two-electrode conductance cell by analyzing ...

A new kind of Durrmeyer-Stancu-type operators
Demonstratio MathematicaThe objective of this study is to examine a class of positive linear operators, defined in terms of the bψ,kλ,μ{b}_{\psi ,k}^{\lambda ,\mu } basis and to analyze their approximation properties. Direct estimates for the (λ,μ)\left(\lambda ,\mu )-Durrmeyer-

(λ, ψ)-Bernstein-Kantorovich operators
Demonstratio MathematicaIn this article, we introduce a new family of (λ,ψ)\left(\lambda ,\psi )-Bernstein-Kantorovich operators which depends on a parameter λ\lambda , derived from the basis functions of Bézier curves and an integrable function ψ\psi .
