A novel heterogeneous coupled neuron network and its application in mechanical fault feature enhancement

In practical engineering, fault characteristic signals are often overwhelmed by strong background noise and complex working conditions, which poses a serious challenge for timely detection and accurate identification of faults. Therefore, a novel heterogeneous coupled neuron netw...

Frequency-Guided Feature Representation for Instance Segmentation in Aerial View Traffic Accident Scenes

Accurate instance-level perception of aerial view traffic accident scenes is the foundation of accident investigation. However, existing accident datasets mainly support event-level video analysis or coarse spatial localization, and rarely provide pixel-level vehicle masks togeth...

Research on cutting parameter optimization for plunge-cutting of cyclo-palloid spiral bevel gears

Cyclo-Palloid spiral bevel gears hold significant application value in high-end equipment manufacturing due to their superior transmission smoothness and high load-bearing characteristics. However, traditional machining processes face technical bottlenecks such as pronounced cutt...

Unraveling the Micromechanisms of Plastic Synergy in TWIP Steel With a Multigradient Structure

Gradient structural design offers a novel and effective strategy to overcome the long‐standing strength‐ductility trade‐off in metallic materials. In the present study, to address the low yield strength of conventional twinning induced plasticity (TWIP) steel, a multigradient str...

Deep learning-based automatic evaluation model for translation quality of master of translation and interpreting

Translation quality assessment functions as a vital component which Master of Translation and Interpreting programs use to evaluate students’ language skills and their translation abilities. Conventional human-based translation scoring is highly subjective, labour-intensive, and...

Effect of mesh-belt motor frequency on heat- transfer boundary conditions and quenching distortion of bearing rings

Quenching distortion of bearing rings seriously affects their dimensional accuracy and service performance in industrial production. To address this issue, this study proposes a distortion control method for bearing rings during quenching in widely used mesh-belt furnaces, focusi...

Evidence driven dual granularity cross modal reasoning for cultural heritage visual language understanding

This paper addresses a critical limitation in vision-language models for cultural heritage understanding, namely the lack of explicit evidence-centered reasoning mechanisms. Existing approaches typically treat visual evidence as a post hoc explanation rather than an intrinsic com...

Unlocking Potential: Luban Workshop’s Contribution to Building a Better Future for Vocational Education in Africa

Abstract In recent years, the Luban Workshop has emerged in China as a key task of internationalizing China’s vocational education and to share teaching resources, teaching models, and professional criteria globally to cultivate talent and train high-end skilled technical personn...

Online Detection and Grading of Tomato External Quality Based on Machine Vision

Abstract Tomato shape and mass are key indicators for external quality evaluation, while manual inspection is inefficient and subjective. This study proposes an online method for tomato external quality detection and grading based on machine vision. Images of 1,000 tomato samples...
