A Hybrid Adaptive Particle Swarm Optimization Algorithm for Enhanced Performance
APPLIED SCIENCES-BASELJiang, Zhengfeng Zhu, Daoheng Li, Xiao-Yu Han, Ling-Bo  出版年:2025
The traditional particle swarm optimization (PSO) algorithm often exhibits defects such as of slow convergence and easily falling into a local optimum. To overcome these problems, this paper proposes an enhanced variant ...
Efficient and Accurate Beach Litter Detection Method Based on QSB-YOLO
INTERNATIONAL JOURNAL OF ADVANCED COMPUTER SCIENCE AND APPLICATIONSZhu, Hanling Zhu, Daoheng Qin, Xue Guo, Fawang  出版年:2023
Because of the potential threats it presents to marine ecosystems and human health, beach litter is becoming a major global environmental issue. The traditional manual sampling survey of beach litter is poor in real-time...
Key Technology of Mixed Matching Circuit for Miniaturizing Dual-Band Antenna
IEEE ACCESSZhu, Daoheng Lu, Daian Yang, Xiaokun Li, Zhiqiang  出版年:2022
A mixed matching circuit for miniaturizing dual-band antenna is introduced and verified in this study. Two L-shaped matching circuit for miniaturization are cascaded to interpret the theory of operation in accordance wit...
Characterizing Post-Storm Beach Recovery Modes: A Field-Based Morphodynamic Study from Dongdao Beach, China
JOURNAL OF MARINE SCIENCE AND ENGINEERINGLiu, Lulu Sun, Yan Liu, Run Zhu, Daoheng Chen, Zhaoguang Li, Zhiqiang  出版年:2025
The post-storm beach recovery process exhibits variability. Understanding its mechanisms is crucial for advancing the study of beach morphodynamics. This study involved a 25-day continuous field observation on Dongdao Be...
Research on Rip Currents Detection Method Based on Improved YOLOv5s
Journal of Computers (Taiwan)Qi, Rui Zhu, Dao-Heng Qin, Xue  出版年:2023
Rip currents are common natural disaster and widely distributed on beaches around the world, which can quickly bring swimmers into deep water and cause safety accidents. Rip currents are generally sudden and insidious, m...
Improved DBSCAN algorithm based on relative mass of the data field
Proceedings of SPIE - The International Society for Optical EngineeringZhu, Daoheng Li, Zhiqiang Hu, Pengpeng Su, Qianxin Liu, Run  出版年:2022
The DBSCAN algorithm can discover clusters of arbitrary shapes, but it has difficulty in predicting the appropriate clustering parameters. In this study, the data field is introduced into the number field space, and the ...
Interannual Variations in Headland-Bay Beach Profiles and Sediment Under Artificial Island Influence: A Case Study of Puqian Bay, Hainan Island, China
JOURNAL OF MARINE SCIENCE AND ENGINEERINGWang, Xuan Li, Zhiqiang Sun, Yan Bian, Xiaodong Zhu, Daoheng  出版年:2025
Beaches are important geomorphic units shaped by land-sea interactions. Changes in thEIr profiles and surface sediments are directly influenced by both natural processes and human activities. This study is based on conti...
Analysis of Sandbar-Trough Bed Level Changes Under Regular Wave Conditions-A Case Study of Ten-Mile Silver Beach, Hailing Island, China
JOURNAL OF MARINE SCIENCE AND ENGINEERINGBian, Xiaodong Li, Zhiqiang Sun, Yan Zhu, Daoheng Chen, Tao Zeng, Chunhua  出版年:2025
Understanding the evolution of the sandbar-trough system under regular wave conditions is essential for revealing the dynamic responses of coastal morphology in non-extreme environments and provides a scientific basis fo...
Development and evaluation of a rip current forecasting system for channel-type rip currents on a low-energy headland beach
GEOMATICS NATURAL HAZARDS & RISKSun, Yan Liu, Lulu Bian, Xiaodong Zhu, Daoheng Li, Zhiqiang  出版年:2025
A 34-day field observation was conducted on a headland beach in South China with a typical channel rip current system. The Delft3D model was applied to reproduce hydrodynamic conditions and extract rip currents, while a ...
