Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 8, Page 1004-1027, 18 March 2025.Abstract This study proposes a multi‐perspective fusion model for operating speed prediction based on knowledge‐enhanced graph neural networks, named RoadGNN‐S. By utilizing message passing and multi‐head self‐attention mechanisms, RoadGNN‐S can effectively capture the coupling impacts of multi‐perspective alignment elements (i.e., two‐dimensional ...

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.1. An adaptive speed control method is proposed to execute the ship formation trajectory tracking task more efficiently and safely while entering port with tidal elevation variations. 2. A distributed ship formation controller based on the leader‒follower structure is designed to govern the coordinated motion of formation members more flexibly. 3.

Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 4, December 2024.Abstract Filament winding is a manufacturing process used in the construction of fiber composite structures, where a thermoset resin impregnated bunch of fibers is deposited on a rotating mandrel. The evolving stress and strain states due to thermal and mechanical loads during the manufacturing process are of particular interest to avoid subsequent ...

The Frenet-Serret formalism and black holes in higher dimensions
, 1988 The Frenet-Serret formalism is applied to the study of Killing trajectories in higher dimensions (five and six). The curvature and the higher torsions are expressed in terms of an effective field strength Fab and their mutual relations established by the

On special curves in Lie groups with Myller configuration
Mathematical Methods in the Applied Sciences, Volume 47, Issue 14, Page 11693-11708, 30 September 2024.In this study, we determine a new type comprehensive frame, which is called the generalized Frenet‐type frame in three‐dimensional Lie groups with Myller configurations, and it includes several special and classical type frames for Euclidean 3‐space and three‐dimensional Lie groups.

Quaternionic Curves Which Lie on the Special Planes in 4−Dimensional Euclidean Space E4
Journal of Mathematics, Volume 2024, Issue 1, 2024.In this study, some curvature conditions of quaternionic curves are obtained by writing the position vectors of quaternionic curves as linear combinations of new vector fields, named as Di (1 ≤ i ≤ 4), that are produced from Frenet frame fields of the quaternionic curves.
