Investigation of tribological behavior of 20NiCrBSi-WC12Co coated brake disc by HVOF method
(Iop Publishing Ltd, 2020)
In braking systems, which consist of dry sliding lining against a pearlitic cast-iron disc, disc wear has a significant impact on the overall wear rate. In this work, dynamometer tests were conducted to find out the friction ...
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, ...
EVALUATION OF MECHANICAL CHARACTERISTICS OF THE INTERLOCKING CONCRETE PAVES PRODUCED FLY ASH
(Kırklareli Üniversitesi, 2020)
Fly ashes are used aspozzolanic admixtures or filler materials in concrete production. Increasingthe use of fly ash is important both in terms of economy and environmentalpollution. The interlocking concrete paves are ...
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 ...
On bicomplex generalized Tetranacci quaternions
(Bulgarian Acad Science, 2020)
In this paper, we introduce the bicomplex generalized Tetranacci quaternions. Furthermore, we present some properties of these quaternions and derive relationships between them.
Children’s perspective on the right of self-determination
(T&K Academic, 2018)
The present study was conducted to determine the thoughts of children, whose lives are governed by decisions taken by adults, on the right to self-determination. The study was conducted as a generic qualitative research, ...
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 ...
Heat transfer of brake pad used in the autos after friction and examination of thermal tension analysis
(2014)
As a result of the friction of brake pads which is one of the factors affecting automobile performances with brake disc, heat energy comes into being. This heat energy causes brake pads to expose to excessive temperature. ...
PT symmetric Floquet topological phase in SSH model
(Elsevier Science Bv, 2018)
We consider periodically modulated Su-Schrieffer-Heeger (SSH) model with gain and loss. This model, which can be realized with current technology in photonics using waveguides, allows us to study Floquet topological ...
Dynamics of a Second-order System of Nonlinear Difference Equations
(Semnan Univ, 2020)
In this paper, we investigate the equilibrium points, stability of two equilibrium points, convergences of negative equilibrium point, periodic solutions, and existence of bounded or unbounded solutions of a system of ...
