ACD-Net: An Abnormal Crew Detection Network for Complex Ship Scenarios.
Sensors (Basel)
November 2024
Article Synopsis
- Abnormal crew behavior significantly contributes to maritime safety issues, highlighting the need for effective detection systems.
- ACD-Net, a two-stage algorithm, is proposed to improve real-time detection of abnormal crew actions using an enhanced YOLOv5s model combined with a CBAM mechanism for better accuracy in complex ship environments.
- The crew identification algorithm (CFA) optimizes face tracking and quality assessment, resulting in high detection accuracy of 92.3% and an identity recognition matching rate of 69.6%, all while maintaining a processing speed of under 39.5 ms per frame.
The complete mitochondrial genome sequence of snake mackerels (Scombroidei, Gempylidae).
Mitochondrial DNA B Resour
June 2020
For the first time, we illuminate the complete mitochondrial genome (mitogenome) sequence of the which is 16,988 bp in size and contains 13 protein-coding (PCGs), 2 rRNA genes, 22 tRNA genes, and one control region.The base composition of the mitogenome is 26.08% A, 26.
View Article and Find Full Text PDFTDMA protocols have attracted a lot of attention for underwater acoustic sensor networks (UWSNs), because of the unique characteristics of acoustic signal propagation such as great energy consumption in transmission, long propagation delay and long communication range. Previous TDMA protocols all allocated transmission time to nodes based on discrete time slots. This paper proposes an efficient continuous time scheduling TDMA protocol (ECS) for UWSNs, including the continuous time based and sender oriented conflict analysis model, the transmission moment allocation algorithm and the distributed topology maintenance algorithm.
