IET Communications, Volume 19, Issue 1, January/December 2025.In this work, we propose a time‐frequency‐polarisation multi‐domain electromagnetic resource allocation (EMRA) method to resolve mutual interference in multi‐platform equipment configurations. Unlike traditional single‐domain allocation approaches, our solution establishes time‐unit operational models with interference‐based optimisation objectives and

Semantic model of ship behaviour based on ontology engineering
The Journal of Engineering, Volume 2018, Issue 16, Page 1746-1752, November 2018., 2018 Given the complex situation of traffic at sea and the large amount of data that grows with the information technology, the ship behaviour cannot be precise recognised or fully expressed based on the raw and noisy data itself. A semantic model of ship behaviour based on ontology engineering is developed in this study.

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.This study presents a dual‐component reliability model for marine radionavigation systems, accounting for both gradual degradation and sudden failures under harsh maritime conditions. The approach integrates failure rate estimation, MTBF analysis and scenario‐based simulation to predict critical operational thresholds and optimise maintenance planning.

LiDAR‐based automated UAV inspection of wind turbine rotor blades
Journal of Field Robotics, Volume 41, Issue 4, Page 1116-1132, June 2024.Abstract The global trend indicates that overall wind energy production, both onshore and offshore, will increase drastically in the next decade. Therefore, presently, much effort is focused on optimizing the operation and maintenance of wind turbines, since these are quite challenging and cost‐intensive.

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.In this paper, a ground‐based experimental system for solar array active vibration suppression has been established. Firstly, in order to establish an accurate model of the solar array, the solar array is regarded as a flexible cantilevered thin plate, and the corresponding dynamical equations are derived using the absolute nodal coordinate method.

A GAIN SCHEDULED CONTROL LAW FOR FIN/RUDDER ROLL STABILISATION OF SHIPS [PDF]
, 2004 International audienceTaking into account the variations of the environment is a means of improving performances of roll stabilisation systems. The ship behaviour is modelled as a MIMO LPV system.

THE NECESSITY OF USING MDO AND OF CHANGING OVER FROM HFO TO MDO (AND VICE VERSA) ON THE EXAMPLE OF TWO REEFER VESSELS [PDF]
, 2010 Uporaba TDG-a na trgovačkim brodovima ima prednost u smislu troškova putovanja u kojima troškovi goriva imaju značajnu ulogu. Ipak, postoje posebne okolnosti pri kojima uporaba LDG-a postaje nužna i dovodi do povećanja ukupnih troškova.

Fin Rudder Roll Stabilisation of Ships: a Gain Scheduling Control Methodology [PDF]
, 2004 International audienceActive control of ship roll is necessary for operability of an important number of ships. As such it has been strongly developed in the past twenty years. Taking into account the variations of the environment is a means of improving
