QUALITATIVE BEHAVIOURS OF A SYSTEM OF NONLINEAR DIFFERENCE EQUATIONS
(Editura Bibliotheca-Bibliotheca Publ House, 2021)
The paper aims to study the dynamics of a system of nonlinear difference equations x(n+1) = x(n-1)y(n) + A, y(n+1) = y(n-1)x(n) + A where is real number. We especially investigate the stability of equilibrium points, ...
Global dynamics of a higher order difference equation with a quadratic term
(Springer Heidelberg, 2021)
In this paper, we investigate the dynamics of the following higher order difference equation x(n+1) = A + B x(n)/x(n-m)(2) with A, B and initial conditions are positive numbers, and m is an element of {2, 3, ...}. Especially ...
The effects of STEM activities on the problem-solving skills of 6-year-old preschool children
(Routledge Journals, Taylor & Francis Ltd, 2021)
In this study, the effects of STEM activities on the problem-solving skills of preschool children were investigated. A two-group (study: n = 18 and control: n = 18) pre-test/post-test/retention test experimental design was ...
Analysis of polyacrylonitrile nanofiber yarn formation in electrospinning by using a conical collector and two oppositely charged nozzles
(Taylor & Francis Ltd, 2021)
Nanofiber production by electrospinning has become a common production method as it is an easy and flexible system producing nanofibrous webs. However, direct spinning of nanofibers into a yarn would lead to conversion of ...
