    • Comparative analysis of YOLOv9–YOLOv12 object detection models on a custom non-open dataset 

      Wang, Q.; Zhang, B.; Wang, C.; Zhang, C. (БНТУ, 2025)
      This paper compares YOLOv9–YOLOv12 object detection models on a custom non-open dataset (6,500 images, 11 classes), all trained for 300 epochs under identical settings. Results show YOLOv12 achieves the highest mAP@0.5 (0.678), outperforming YOLOv9 (0.648), YOLOv10 (0.603), and YOLOv11 (0.649). Architectural optimizations and training stability drive performance disparities, with ...

    • Optimization and thermal management of battery power supply system for agricultural drones 

      Lin, Q.; Dubinin, S. V.; Wu, L.; Wang, K.; Li, X.; Wang, Q. (БНТУ, 2025)
      Addressing the issues of sudden range reduction and lifespan degradation in agricultural drone lithiumion batteries due to temperature runaway during high-temperature operations, this paper proposes an optimization method for an electric drive battery power supply system. The study initially constructs a battery thermoelectric coupling model to analyze the dynamic relationship ...
