On generalized null Mannheim curves in E24

Mathematical Methods in the Applied Sciences, 2020
In the present paper, we introduce the notion of Cartan‐framed generalized null Mannheim curves in four‐dimensional semi‐Euclidean space with index 2, . We obtain the Cartan (or Frenet) frames and curvature functions of the generalized Mannheim mate curve by the help of curvature functions and Cartan frames of the generalized null Mannheim curve.

Evolution of quaternionic curve in the semi‐Euclidean space E24

Mathematical Methods in the Applied Sciences, 2020
In this paper, kinematics of semi‐real quaternionic curve in semi‐Euclidean space is obtained in terms of its curvature functions. The evolution equation of Frenet frame and curvatures of quaternionic curve are obtained. Also, examples of evolution equations of curvatures are given.

On the quaternionic inclined curves in the semi-Euclidean space E24

Applied Mathematics and Computation, 2004
In this paper, we studied quaternion valued functions and quaternionic inclined curves in the semi-Euclidean space E"2^4. We give Serret-Frenet formulae for the quaternionic curve in the semi-Euclidean space E"2^4. Then we define quaternionic inclined curves and harmonic curvatures for the quaternionic curves in the semi-Euclidean space E"2^4.

Adhesion strength of copper thin-films to a E24 carbon steel: effects of substrate surface ion bombardment etching

Journal of Adhesion Science and Technology, 1993
The scratch test was applied to determine the adhesion strength of d.c. magnetron sputtered copper films onto E24 carbon steel substrates. Some of the substrates were mechanically polished and directly coated with copper; others were ion-etched with argon ions after mechanical polishing and before coating.

General rotational surfaces with pointwise 1-type Gauss map in pseudo-Euclidean space E24

Indian journal of pure and applied mathematics, 2015
In this paper, we study general rotational surfaces in the 4- dimensional pseudo-Euclidean space $$\mathbb{E}_2^4$$ and obtain a characterization of flat general rotation surfaces with pointwise 1-type Gauss map in $$\mathbb{E}_2^4$$ and give an example ...
