Modelling Healthy Operations of Generator Bearings in Wind Farms
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 ...

Dynamic time warping (DTW) is a widely used metric for comparing time series data, offering elasticity in alignment. While the original DTW allows infinite elasticity without penalty, the wDTW imposes a constant penalty regardless of elastic length.

ABSTRACT Reliable extraction of dolphin whistle contours is fundamental for scalable analyses of vocal identity, repertoire structure, and individual‐based acoustic monitoring. We evaluated four algorithms for fundamental frequency estimation of common bottlenose dolphin (Tursiops truncatus) whistles, leveraging a benchmark dataset of annotated ...

Irrigation Impact on Humid Heat Stress: Divergent Metrics, Vegetation Dynamics, and Future Worsening
Abstract Irrigation impact on heat comfort is controversial due to its opposing effects of cooling and humidification, especially over the North China Plain under global warming. While heat stress indices exhibit different responses, the omission of dynamic vegetation adds further uncertainty.

Adapted Empirical Modeling of Near‐Sun Solar‐Wind Speeds for Use in Ensemble Forecasts
Abstract Solar wind science and forecasting relies on empirical relations between modeled coronal magnetic‐field structure—particularly flux‐tube expansion and distance to coronal hole boundary—and solar‐wind speed. There is lots of uncertainty in these relations, creating large uncertainties in the inner‐boundary conditions to heliospheric models ...

Abstract Climate change and human activities jointly affect runoff generation and non‐point source pollutant transport in river basins. Quantifying their relative roles is essential for explaining pollutant‐load changes and informing water resources management. Here, this study developed an integrated framework combining Budyko runoff attribution, Soil
