Field observation and numerical analysis of rip currents at Ten-Mile Beach, Hailing Island, China
ESTUARINE COASTAL AND SHELF SCIENCEHu, Pengpeng Li, Zhiqiang Zhu, Daoheng Zeng, Chunhua Liu, Run Chen, Zhaoguang Su, Qianxin  出版年:2022
Rip currents are a type of high-speed cross-shore current that occur in coastal areas. They are one of the deadliest natural hazard that occur along coasts. At Ten-Mile Beach on Hailing Island in Yangjiang, China, there ...
Application of the Coastal Hazard Wheel for Coastal Multi-Hazard Assessment and Management in the Guang-Dong-Hongkong-Macao Greater Bay Area
SUSTAINABILITYSu, Qianxin Li, Zhiqiang Li, Gaocong Zhu, Daoheng Hu, Pengpeng  出版年:2021
The coasts of Guangdong-Hong Kong-Macao Greater Bay Area (GBA) are facing threats and challenges from rising sea levels, frequent extreme events and human intervention. In this study, the Coastal Hazard Wheel (CHW) was u...
YOLO-Rip: A modified lightweight network for Rip currents detection
FRONTIERS IN MARINE SCIENCEZhu, Daoheng Qi, Rui Hu, Pengpeng Su, Qianxin Qin, Xue Li, Zhiqiang  出版年:2022
Rip currents form on beaches worldwide and pose a potential safety hazard for beach visitors. Therefore, effectively identifying rip currents from beach scenes and providing real-time alerts to beach managers and beachgo...
Coastal erosion risk assessment of Hainan Island, China
ACTA OCEANOLOGICA SINICASu, Qianxin Li, Zhiqiang Li, Gaocong Zhu, Daoheng Hu, Pengpeng  出版年:2023
Coastal erosion on islands is increasing due to sea level rise, frequent extreme events, and anthropogenic activities. However, studies on the multifactorial coastal erosion risk and the vulnerability of islands are limi...
Nearshore significant wave height prediction based on MIC-LSTM model
EARTH SCIENCE INFORMATICSLi, Yan Qin, Xue Zhu, Daoheng  出版年:2023
The near-shore sea area, which is a region of frequent human activities, is important to explore the causes of meteorological factors that are close to human activities in it. A prediction model based on the fusion of ma...
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 ...
Bed level changes in the surf zone during post-storm beach recovery
FRONTIERS IN MARINE SCIENCEHu, Pengpeng Li, Zhiqiang Zeng, Chunhua Zhu, Daoheng Liu, Run Su, Qianxin Tang, Jieping Zhu, Yamin  出版年:2023
The study of post-storm beach recovery is important for economic development and the protection of life in coastal areas. In this study, field observations were conducted for 21 days in the surf zone of Dongdao Beach, Ha...
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...
