Surface Family with Bertrand Curves as Joint Asymptotic Curves in 3D Galilean Space

open access: yesMathematics, 2023
The primary objective of this work is to discuss a surface family with the similarity of Bertrand curves in 3D Galilean space. Subsequently, by applying the Serret–Frenet frame, we estimate the sufficient and necessary statuses of a surface family with ...

Surface Pencil Couple with Bertrand Couple as Joint Principal Curves in Galilean 3-Space

open access: yesAxioms, 2023
A principal curve on a surface plays a paramount role in reasonable implementations. A curve on a surface is a principal curve if its tangents are principal directions.

Surface Family Pair with Bertrand Pair as Common Geodesic Curves in Galilean 3-Space 𝔾3

open access: yesMathematics, 2023
This paper is about deriving the necessary and sufficient conditions of a surface family pair with a Bertrand pair as common geodesic curves in Galilean 3-space G3. Thereafter, the consequence for the ruled surface family pair is also deduced. Meanwhile,

Constant Mean Curvature Surfaces Along a Spacelike Curve

open access: yesCumhuriyet Science Journal, 2022
We construct constant mean curvature surfaces along a given spacelike curve in 3 dimensional Minkowski space. We parametrically present these surfaces using the famous Frenet frame of the curve in question.

A Surface Family with a Mutual Geodesic Curve in Galilean 3-Space G3

open access: yesMathematics, 2023
This article gives an approach for establishing a surface family with a mutual geodesic curve in Galilean 3-space G3. Given a smooth space curve, we derive the sufficient and necessary condition for the given curve to be geodesic on it.

Ambient Noise Data Processing to Obtain Group Velocity for Subsurface Structure Identification: Preliminary Research in Hululais Geothermal Field, Sumatra, Indonesia

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology, 2023
Hululais area lies in the pull-apart basins of the Ketaun Segment and Musi Segment fault as a part of the Sumatra Fault Zone (SFZ). The boundary normal faults of pull-apart basins play an important role as major discharge zones for geothermal fluid ...

Real-Time 3D Reconstruction Pipeline for Room-Scale, Immersive, Medical Teleconsultation

open access: yesApplied Sciences, 2023
Medical teleconsultation was among the initial use cases for early telepresence research projects since medical treatment often requires timely intervention by highly specialized experts. When remote medical experts support interventions, a holistic view
