Stochastic Geodesics [PDF]

open access: green, 2021
We describe, in an intrinsic way and using the global chart provided by Ito's parallel transport, a generalisation of the notion of geodesic (as critical path of an energy functional) to diffusion processes on Riemannian manifolds. These stochastic processes are no longer smooth paths but they are still critical points of a regularised stochastic ...

An investigation of strong edge geodesic number on m-polar fuzzy environment and its application. [PDF]

open access: yesPLoS ONE
For crisp graphs, the notion of edge geodesic numbers has been known for a long time. But lately, the focus has shifted to investigating this idea in fuzzy graphs, which has resulted in studies of a number of properties.

A Geodesic-Based Riemannian Gradient Approach to Averaging on the Lorentz Group [PDF]

open access: goldEntropy, 2017
In this paper, we propose an efficient algorithm to solve the averaging problem on the Lorentz group O ( n , k ) . Firstly, we introduce the geometric structures of O ( n , k ) endowed with a Riemannian metric where geodesic could be ...

On Learning the Geodesic Path for Incremental Learning [PDF]

open access: yesComputer Vision and Pattern Recognition, 2021
Neural networks notoriously suffer from the problem of catastrophic forgetting, the phenomenon of forgetting the past knowledge when acquiring new knowledge.

Geodesic motion in Euclidean Schwarzschild geometry [PDF]

open access: yesThe European Physical Journal C, 2022
This paper performs a systematic investigation of geodesic motion in Euclidean Schwarzschild geometry, which is studied in the equatorial plane. The explicit form of geodesic motion is obtained in terms of incomplete elliptic integrals of first, second ...

Geodesic incompleteness of some popular regular black holes [PDF]

open access: yesPhysical Review D, 2022
Throughout the study of the geodesics of some popular spherically symmetric regular black holes, we hereby prove that the analytically extended Hayward black hole is geodetically incomplete.

Object-Based Image Analysis (OBIA) and Machine Learning (ML) Applied to Tropical Forest Mapping Using Sentinel-2

open access: yesCanadian Journal of Remote Sensing, 2023
The purpose of this research was to distinguish and estimate natural forest areas at ParanĂ¡, Brazil. Forest plantations (Silviculture) and natural forests have high annual vegetative vigor, as well as agricultural areas in the periods of agricultural ...

Hyperbolic Center of Mass for a System of Particles in a Two-Dimensional Space with Constant Negative Curvature: An Application to the Curved 2-Body Problem

open access: yesMathematics, 2021
In this article, a simple expression for the center of mass of a system of material points in a two-dimensional surface of Gaussian constant negative curvature is given.

VMNet: Voxel-Mesh Network for Geodesic-Aware 3D Semantic Segmentation

open access: yesIEEE International Conference on Computer Vision, 2021
In recent years, sparse voxel-based methods have be-come the state-of-the-arts for 3D semantic segmentation of indoor scenes, thanks to the powerful 3D CNNs.

Quasihyperbolic geodesics are hyperbolic quasi-geodesics [PDF]

open access: yesJournal of the European Mathematical Society, 2020
This is a tale describing the large scale geometry of Euclidean plane domains with their hyperbolic or quasihyperbolic distances. We prove that in any hyperbolic plane domain, hyperbolic and quasihyperbolic quasi-geodesics are quantitatively the same curves. We also demonstrate the simultaneous Gromov hyperbolicity of such domains with their hyperbolic
