Characterisation of Hedge Burning in the Context of Wildland Urban Interface (WUI) Fire Prevention

Fire and Materials, EarlyView.
ABSTRACT With global warming, the wildfire season tends to get longer, causing fatalities and devastating damage to human property. Although many countries have implemented fire risk prevention measures, particularly in Wildland Urban Interfaces (WUI), this finding shows that there are weaknesses in the prevention measures. This is mainly due to a lack

Asynchronously finite‐time fault detection for switched systems with unstable modes and intermittent measurements

IET Control Theory &Applications, Volume 17, Issue 2, Page 172-191, January 2023., 2023
Abstract This study proposes a novel fault detection (FD) filter design approach for switched systems with unstable modes and intermittent measurement; the FD filter design approach considers asynchronous switching and ensures finite‐time stability (FTS).

SDF‐Guided Point Cloud Generation Framework for Mesh‐Free CFD

International Journal for Numerical Methods in Fluids, EarlyView.
This paper presents different methods for generating clouds of points around objects for use with meshless methods in computational fluid dynamics. This image shows the cloud generated around the original ROBIN body. ABSTRACT Meshing is a bottleneck of CFD workflows, especially when complex geometries are considered.

A geometric approach to reach‐avoid games with time limits

IET Control Theory &Applications, Volume 17, Issue 2, Page 192-209, January 2023., 2023
Abstract The differential games have been widely used to analyze the conflicts between intelligent agents. Motivated by the fact that the agents always have finite energy or time requirements, a novel reach‐avoid game with time limits is investigated in this work.

Abstract Conformer Space

Helvetica Chimica Acta, Accepted Article.
Pairwise distance root mean square deviation defines a hyperspace where conformers with similar shape reside close to each other. The radius of gyration of protein ensembles in this abstract conformer space (ACS) converges at ensemble sizes between 50 and 500, depending on the extent of disorder.

Multi‐view short‐term photovoltaic power prediction combining satellite images feature learning and graph mutual information feature representation

IET Computer Vision, EarlyView., 2023
This paper explores the cloud information elements of the satellite images from a multi‐view perspective, and performs feature extraction and processing of the meteorological information it contains to learn the impact of cloud cover on photovoltaic (PV) prediction.

Enhance decoding of lower limb motor imagery‐electroencephalography patterns by Riemannian clustering

Interdisciplinary Medicine, EarlyView.
Abstract Brain‐Computer Interface (BCI) based on motor imagery (MI) has attracted great interest as a new rehabilitation method for stroke. Riemannian geometry‐based classification algorithms are widely used in MI‐BCI due to their strong robustness and generalization capabilities.
