Field‐Data‐Based Wind Turbine Reliability Modelling: Quantifying Effects of Operating Age, Design and Technological Development

open access: yesWind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT As wind energy continues to expand, ensuring the reliability of wind turbines is critical for optimising operational efficiency and minimising downtime. Based on maintenance data from over 1,000 onshore and offshore wind turbines covering more than 4200 operating years, this study presents an analysis of wind turbine failure behaviour over ...

Failure Analysis and Maintenance Planning for Repairable Deteriorating Structural Systems Subject to Imperfect Maintenance

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 3, Page 992-1008, April 2026.
ABSTRACT The analysis of a system that deteriorates under imperfect maintenance is essential in reliability engineering. Imperfect maintenance does not fully restore a system to its original condition, leading to complex degradation patterns. Statistical inference techniques allow for precise estimation of degradation parameters, maintenance effects ...

And then there were none: decrease of origination and the decline of Conulariida

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract Although the evolutionary history of conulariids has been widely studied, previous works have focused mostly on limited time intervals. In this paper, we examine the diversity dynamics of the group throughout its entire history, using various mathematical approaches.

Enhancing UAV and Bird Target Detections With Use of Monte Carlo Simulation Method

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
His paper presents a Monte Carlo‐based approach for enhancing the detection of low‐RCS aerial targets, such as UAVs and birds, using compact X‐band radar systems operating in cluttered environments. The proposed method, validated with real ENAVI radar measurements, enables realistic synthetic echo generation and adaptive optimisation of radar detection
