Non-null slant ruled surfaces

open access: yesAIMS Mathematics, 2019
In this study, we define some new types of non-null ruled surfaces called slant ruled surfaces in the Minkowski 3-space $E_{1}^{3} $. We introduce some characterizations for a non-null ruled surface to be a slant ruled surface in $E_{1}^{3} $.

Covering rational ruled surfaces

open access: greenMathematics of Computation, 2017
We present an algorithm that covers any given rational ruled surface with two rational parametrizations. In addition, we present an algorithm that transforms any rational surface parametrization into a new rational surface parametrization without affine base points and such that the degree of the corresponding maps is preserved.

Evolutions of partner-ruled surfaces with simultaneous inextensibility conditions. [PDF]

open access: yesPLoS ONE
Ruled surfaces are a class of surfaces generated by a moving straight line and are used in various design and modeling applications, including kinematics, robotics, and computer-aided geometric design.

Geometry of the normal ruled surfaces

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2021
The wide circle of the surfaces formed by the motion of the right line in the normal plain of some base directrix curve is regarded. The generate right line may rotate at some low at the normal plane of the base curve.

The Intersection of Two Ruled Surfaces Corresponding to Spherical Indicatrix Curves on the Unit Dual Sphere

open access: yesCumhuriyet Science Journal, 2023
In this study, we first investigate the intersection of two different ruled surfaces in R^3 for two different tangential spherical indicatrix curves on DS^2 using the E. Study mapping.

Spacelike ruled surfaces with stationary Disteli-axis

open access: yesAIMS Mathematics, 2023
This paper derives the expressions for spacelike ruled surfaces with stationary Disteli-axis by means of the E. Study map. This provides the ability to compute a set of Lorentzian curvature functions which define the local shape of spacelike ruled ...

Ruled surfaces with constant Disteli-axis

open access: yesAIMS Mathematics, 2020
This work develops the kinematic-geometry for ruled surfaces by using the analogy with spherical kinematics. This provides the ability to compute set of curvature functions which define the local shape of ruled surfaces. Hence, the well known equation of

Simultaneous Developability of Partner Ruled Surfaces according to Darboux Frame in E3

open access: yesAbstract and Applied Analysis, 2021
In this paper, we introduce original definitions of Partner ruled surfaces according to the Darboux frame of a curve lying on an arbitrary regular surface in E3.

Simultaneous characterizations of partner ruled surfaces using Flc frame

open access: yesAIMS Mathematics, 2022
In this study, we introduce partner ruled surfaces according to the Flc frame that is defined on a polynomial curve. First, the conditions of each couple of two partner ruled surfaces to be simultaneously developable and minimal are investigated.
