Floating two-body wave energy converters (WECs) exhibit advantages, including insensitivity to water depth and tidal range, along with adaptability to multi-level sea states. However, WECs suffer from drawbacks, including unstable power generation and low wave energy capture efficiency. To enhance the hydrodynamic performance and energy capture efficiency, a dish-shaped buoy and perforated damping plate configuration was desig...

In this study, a novel wind-wave energy hybrid concept is proposed, consisting of a Three Gorges Leading semi-submersible floating wind turbine and multiple point absorption wave energy converters (WECs). Based on three-dimensional potential flow theory, numerical simulations are conducted using the hydrodynamic analysis software AQWA. The existing experimental data are used to validate the reliability of the numerical model b...

The detection and surveillance of ship targets in coastal waters is not only a crucial technology for the advancement of ship intelligence, but also holds great significance for the safety and economic development of coastal areas. However, due to poor visibility in foggy conditions, the effectiveness of ship detection in coastal waters during foggy weather is limited. In this paper, we propose an improved version of YOLOv8s,...

PM2.5 derived from automobile exhaust can cause reproductive impairment in adult males, but the toxic effects of PM2.5 exposure on reproductive function in juvenile male rats and its relationship with ferroptosis have not been reported. In this paper, 30-day-old juvenile male Sprague-Dawley (SD) rats were divided into four groups (blank control, vitamin control, PM2.5, and PM2.5+Vitamin). The blank control group was fed normal...
