Topology Optimization Method for Trajectory Control of Particle Through Fluid‐Structure Interaction

International Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT This research develops a new topology optimization (TO) scheme to manipulate the trajectory of particle suspended in fluid by reverting fluid motion by fluid‐structure interaction (FSI). The simulation of particle trajectory considering the effect of FSI is both challenging and largely unexplored in the context of TO, and the TO of particle ...

A Voronoi Diagram‐Based Approach for AC Optimal Power Flow

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper presents a new approach for AC optimal power flow. The proposed approach begins by constructing a Voronoi diagram using a set of initial sample points that represent candidate solutions distributed across the search space. It then iteratively adds new sample points, including: (i) a tentative optimal point obtained via the continuous ...

Convex Hull of Points Lying on Lines in o(n log n) Time after Preprocessing

, 2011
Motivated by the desire to cope with data imprecision, we study methods for taking advantage of preliminary information about point sets in order to speed up the computation of certain structures associated with them.

Safety‐Critical Kinematically‐Executable Overtake Planning via Contingency Path‐Speed Iterative Algorithm for Automated Valet Parking*

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
Motion planning in automated valet parking (AVP) confronts a series of formidable challenges, including a constricted movement space, vehicles parked in violation of regulations, and vehicles that intrude suddenly. In response to these issues, this article devises a safety‐critical kinematically executable overtaking planning system for AVP through a ...

Collaborative Methods of Resolving Road Graphic Conflicts Based on Cartographic Rules and Generalization Operations

ISPRS International Journal of Geo-Information
The resolution of road graphic conflicts is a key aspect of map generalization, which involves both scale reduction and the symbolization of map features. This study proposes collaborative methods of road graphic conflict resolution considering different

Propagating Updates of Residential Areas in Multi-Representation Databases Using Constrained Delaunay Triangulations

ISPRS International Journal of Geo-Information, 2016
Updating topographic maps in multi-representation databases is crucial to a number of applications. An efficient way to update topographic maps is to propagate the updates from large-scale maps to small-scale maps.

A Hybrid A*‐APF Path Planning Method for Ships Entering the Berthing Waters

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper presents a two‐stage hybrid path planning approach for ship berthing: the first stage builds an accurate environmental model based on berth features and the second stage combines an improved A* algorithm (with directional consistency penalty) and the artificial potential field method to generate feasible paths and enhance local obstacle ...

A Variational r-Adaption and Shape-Optimization Method for Finite-Deformation Elasticity [PDF]

, 2003
This paper is concerned with the formulation of a variational r-adaption method for finite-deformation elastostatic problems. The distinguishing characteristic of the method is that the variational principle simultaneously supplies the solution, the ...

There are Plane Spanners of Maximum Degree 4

, 2014
Let E be the complete Euclidean graph on a set of points embedded in the plane. Given a constant t >= 1, a spanning subgraph G of E is said to be a t-spanner, or simply a spanner, if for any pair of vertices u,v in E the distance between u and v in G is ...
