Geometric Structures on Graphs: a Holonomy-Based Discretization of Curvature

We propose a holonomy-based framework for discretizing curvature on graphs equipped with local symmetric positive-definite metrics. Each vertex carries a fibre metric \(g_i\), and each directed edge carries a reversible metric-compatible transport \(F_{ij}\). The ordered product around an oriented triangular loop \(\ma...

Fiber Bragg grating sensing and compound fault diagnosis for key component of wind turbines

Wind power is an important part of the energy transition, and the wind turbine gearbox is a core transmission component of wind power generation systems. Effective detection and identification of gearbox compound faults are therefore important for ensuring the stable and safe operation of wind turbines. This paper prop...

Long-Tailed Multi-Label Diagnosis of Compound Faults in Wind Turbine Gearboxes via Multi-Channel Imaging of FBG Vibration Signals

Wind power plays an important role in renewable energy generation, and the reliability of wind turbine gearboxes directly affects turbine operation and maintenance. Compound gear fault diagnosis remains challenging because multiple fault components may coexist and compound fault samples are often limited, leading to lo...
