A Cross-Modal Consistency and Reliability-Aware Fusion Network for Railway Foreign-Object Segmentation

Real-time segmentation of foreign objects between rails is essential for high-speed railway inspection. Single-modality perception remains limited because two-dimensional images provide rich texture but lack depth, whereas point clouds provide geometry but are weak in color and m...

Intelligent sensor-based fault diagnosis and tool wear prediction for CNC milling using hybrid machine learning

Abstract Computer Numerical Control (CNC) machining plays a crucial role in modern manufacturing, where the condition of cutting tools directly affects product quality, production efficiency, and maintenance costs. Accurate monitoring of tool wear and fault conditions is therefor...

Rail Light-Strip Abnormality Analysis from Color Inspection Images Using an Improved SegFormer and Geometric Rules

Rail light-strip morphology reflects the wheel-rail contact condition. Reliable automatic analysis remains difficult. The strip is narrow and has weak boundaries, while specular reflection, rail-head texture and trackside background interfere with color inspection images. This st...

Research on Mechanism of Fatigue Life Enhancement in Ball Bearings by Residual Compressive Stress

While the beneficial effect of residual compressive stress (RCS) on rolling bearing fatigue life is empirically well-established, the underlying mechanisms, particularly its influence on the subsurface stress field responsible for fatigue initiation, remain inadequately explored....
