Spherical Darboux images of curves on surfaces

S Hananoi, N Ito, S Izumiya - … zur Algebra und Geometrie/Contributions to …, 2015 - Springer
For a regular curve on a surface, we have a moving frame along the curve which is called
the Darboux frame. We induce three special vector fields along the curve associated to the …

A novel technique to detect caries lesion using isophote concepts

S Datta, N Chaki, B Modak - IRBM, 2019 - Elsevier
Abstract Background and Objectives Dental caries is one of the most common painful and
infectious oral diseases. Early detection of caries lesion prevents the spreading of infection …

On non-null relatively normal-slant helices in Minkowski 3-space

E Nešović, U Öztürk, ÖEB Koç - Filomat, 2022 - doiserbia.nb.rs
By using the Darboux frame| ξ, ζ, η| of a non-null curve lying on a timelike surface in
Minkowski 3-space, where ξ is the unit tangent vector of the curve, η is the unit spacelike …

[PDF][PDF] Relatively normal-slant helices lying on a surface and their characterizations

M Düldül - Hacettepe Journal of Mathematics and Statistics, 2017 - dergipark.org.tr
In this paper, we consider a regular curve on an oriented surface in Euclidean 3-space with
the Darboux frame {T,U,V\} along the curve, where T is the unit tangent vector field of the …

On k‐type null Cartan slant helices in Minkowski 3‐space

E Nešović, EB Koç Öztürk… - Mathematical Methods in …, 2018 - Wiley Online Library
In this paper, we define k‐type null Cartan slant helices lying on a timelike surface in
Minkowski space according to their Darboux frame, where k∈{0, 1, 2}. We study these …

Some characterizations of pseudo null isophotic curves in Minkowski 3-space

E Nešović, U Öztürk, EBK Öztürk - Journal of Geometry, 2021 - Springer
In this paper, we define and characterize pseudo null isophotic curves lying on a non-
degenerate surface in Minkowski 3-space. We find the relation between Darboux frame's …

Framed isophote curves on the framed surface

Z Li, P Li, D Pei - Optik, 2023 - Elsevier
The isophote curve on surfaces is an important consequence of Lambert reflect law in
optical research. In this paper, we define the framed isophote curve along a surface which …

Numerical computing of isophote curves, general helices, and relatively normal‐slant helices in Minkowski 3‐space

U Öztürk, E Nešović… - Mathematical Methods in …, 2024 - Wiley Online Library
In this paper, we present a method for numerical computing of some characteristic kinds of
non‐null curves lying on a non‐degenerate surface in Minkowski space 𝔼 1 3. Namely, we …

Isophote curves on timelike surfaces in Minkowski 3-space

F Dogan - arXiv preprint arXiv:1203.4389, 2012 - arxiv.org
Isophote comprises a locus of the surface points whose normal vectors make a constant
angle with a fixed vector. In this paper, isophote curves are studied on timelike surfaces in …
