Design and Implementation of a Digitalised Marine Aids to Navigation Monitoring System for High‐Density Maritime Traffic Waters: A Case Study of the Strait of Malacca

Applied Research, Volume 5, Issue 5, October 2026.
A digitalised Aids‐to‐Navigation monitoring system (ARMS) was deployed across 478 installations in the Strait of Malacca and Malaysian waters, integrating multi‐sensor edge validation, hybrid AIS/VHF/cellular communication, and a centralised platform. It achieved 98.3% availability and cut fault‐detection time from weeks to just 8.4 min.

Laser Surface Treatment of Nickel‐Alumina Coating for Enhancement of Erosion and Corrosion Resistance of High Speed Steel Vanes

Applied Research, Volume 5, Issue 5, October 2026.
Laser surface treatment was carried out to enhance the performance of Ni‐Al2O3 coatings on HSS substrates. The results revealed improved microstructural features, corrosion resistance and significant reduction in slurry erosion wear with 18 W laser treatment. ABSTRACT The sliding wear between hydraulic vane tip and the inner surface of the cam ring can

A 7‐Year Eddy Covariance Dataset of the Energy, Water Vapour and Carbon Dioxide Fluxes Observed in a Siberian Dwarf Pine Ecosystem

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
To clarify the role of alpine ecosystems in water and carbon cycling, we measured eddy‐covariance fluxes in a Siberian dwarf pine ecosystem in the Japanese Alps. The quality of the flux data was assessed using micrometeorological criteria, and data gaps were filled using a random forest regression approach.

Beyond Blind Trust in Hospital Data Warehouses: Evaluating Real‐World Data Accountability

Learning Health Systems, Volume 10, Issue 4, October 2026.
ABSTRACT Introduction The reliability of real‐world evidence (RWE) depends on data accuracy and secondary users' ability to evaluate how data are generated and transformed. Although recent frameworks emphasize provenance, transparency, and auditability, their practical assessment in routine hospital settings remains unclear.

Modelling Healthy Operations of Generator Bearings in Wind Farms

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT This study investigates the consistency and impact of feature selection methods on deterministic and probabilistic normal behaviour models (NBMs) for estimating rear generator bearing temperature in wind farms using SCADA data. Rigorous NBM development enables the transfer of key features, enhances anomaly detection comparability and ...
