Numerical Prediction of Deformation‐Induced Martensitic Transformation in Cold‐Sprayed Austenitic Stainless Steel

steel research international, Volume 97, Issue 4, Page 2241-2249, April 2026.
Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Weibull‐Neural Network Framework for Wind Turbine Lifetime Monitoring and Disturbance Identification

Wind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT Wind turbines are vital for sustainable energy, yet their reliability under diverse operational and environmental conditions remains a challenge, often leading to costly failures. This study presents a novel Weibull‐Neural Network Framework to enhance wind turbine lifetime monitoring by estimating reliability (R(t)) and mean residual life (MRL)

Power Quality‐Oriented Multiloop Design of Floating Wind Turbines Pitch Control

Wind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT Floating offshore wind turbines (FOWTs) face inherent control limitations in above‐rated operating conditions due to right‐half‐plane zeros in the blade‐pitch‐to‐rotor‐speed dynamics, which restrict achievable control bandwidth and may lead to closed‐loop instability.

movetrack: An R package to model flight paths from radio‐telemetry networks

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1069-1081, April 2026.
Abstract Tracking small‐ to large‐scale movements of animals is important for studying their interactions with the environment, including how they adjust and adapt their migration in response to environmental and human‐induced changes. Despite the technical progress in tracking devices, a major challenge remains for small animals—such as songbirds ...
