Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Waterborne polyurethane/graphene formulations are developed as piezoresistive coatings on glass fabric to enable flexible strain sensing. The graphene‐enabled conductive network provides a stable electromechanical response under cyclic compression. The coating demonstrates reliable pressure‐dependent resistance changes, highlighting its potential for ...

Disrupted Skies: How Offshore Wind Farms Alter Flight Behavior of Breeding Seabirds
Using high‐resolution 1‐s tracking bursts collected every hour, we quantified within‐trajectory flight behavior of breeding Bridled Terns near offshore wind farms. Birds showed increased mean redirection and lower flight altitude when trajectories were more closely aligned with turbine directions from the colony, suggesting localized, direction ...

Finite element and Campbell analyses evaluated noise and vibration in a tri‐lobe compressor. A critical speed of 243 rad/s due to backward whirl was identified. Modal and static results revealed vibration hotspots at flanges and lobe tips. Design optimization enhances structural integrity, reduces resonance risk, and minimizes noise emission.

AWT‐YOLO: Lightweight Rail Surface Defect Detection Algorithm Based on YOLOv11 Improvement
The proposed improvement route and method architecture related to this study. ABSTRACT Railway safety and operational reliability critically depend on timely and accurate inspection of rail infrastructure. Nevertheless, existing visual neural network‐based inspection methods frequently fail to achieve an optimal balance between detection accuracy and ...

Adaptive Fuzzy Energy Management of Wind‐Battery Systems With Flexible Desalination Load
An adaptive fuzzy energy management strategy is proposed for a wind‐battery‐powered reverse osmosis desalination system. The controller dynamically adjusts the desalination load based on wind power availability and the battery state of charge to reduce battery stress.

Hydrogen‐based long‐duration energy storage (LDES) converts surplus renewable electricity into hydrogen through electrolysis, stores it using suitable storage technologies, and reconverts it into electricity, heat, or transport fuels. AI‐driven optimization, digital twins, and techno‐economic, environmental, and reliability assessments enable efficient,

Mixed Precision Augmented GMRES
ABSTRACT We aim to accelerate the restarted generalized minimal residual (GMRES) method for the solutions of linear systems by combining two types of techniques. On the one hand, mixed precision GMRES algorithms, which use lower precision in certain steps of the inner cycles, offer significant reductions in computational and memory costs.
