Study on key technologies for air–water surface collaboration of observation unmanned aircraft vehicle

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
To address the issues of short flight duration and the inability to carry high‐computation resources in small observation unmanned aerial vehicles (UAVs) due to limited energy and payload capacities, a deployment framework is proposed for an air–water surface collaborative observation system based on energy replenishment and computation offloading.

PBM‐YOLO: A Performance Balanced Floating Garbage Detection Model for Water Surface Environments

open access: yesIET Image Processing, Volume 19, Issue 1, January/December 2025.
We propose a lightweight detection model, PBM‐YOLO, for floating garbage detection on water surfaces. Based on YOLOv8n, the model introduces a feature extraction module (FSEM) that integrates frequency and spatial information to enhance object representation.

A MILP Model and Two‐Stage Heuristic Algorithm for Vehicle‐Assisted Multi‐Drone Inspection Routing Problem

open access: yesIET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This paper presents a novel solution for the vehicle‐assisted multi‐drone inspection routing problem (VAMDIRP) using a mixed‐integer linear programming (MILP) model solvable by GUROBI for small instances and a two‐stage heuristic algorithm for larger cases.

Ship Formation Control Using Nonlinear Model Predictive Control With Safe Speed Constraints and Tidal Elevation Variations

open access: yesIET 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.
