For the study on the multi-UAV cooperative execution of complex tasks, this paper divides multi-UAV cooperative tasks planning into three parts: task allocation, path planning and trajectory tracking. Firstly, the specified task is assigned for each UAV by choosing Hungarian algorithm as the task allocation algorithm. Secondly, an improved Informed-RRT* algorithm is employed to plan the trajectory of the multi-UAV system. Then, a trajectory tracking controller is designed by using a model predictive control method. Finally, the simulation results are carried out to verify the effectiveness of the designed method.

An efficient method is presented for the prediction of the ship structure-borne noise. Statistical Energy Analysis (SEA) is used, and the equations used for the SEA parameters are also presented. Traditionally, the SEA method requires a great deal of work after structures are modelled. It is almost laborious and time-consuming to set damping loss factors and excitation loads for large structures such as ships. In the presented method, the secondary development of VA One is applied, and the processing programs are used in the context of Matlab. Through the secondary development, setting of damping loss factor and loading, solving of SEA model have been carried out. The effectiveness of the present method is illustrated by the computer run of the box model, which containing 16 plate subsystems and 3 acoustic cavity subsystems. The effects of damping loss factors are discussed. © The Institution of Engineering & technology 2023.

The fusion of camera and LiDAR features in the Bird's Eye View (BEV) perspective has become a prevalent solution for 3D detection in autonomous driving due to its simplicity and efficiency. However, in challenging environments like mining areas with dusty roads, existing BEV-based fusion networks struggle due to dust occlusion and misidentification of dust as obstacles. To address this, we propose a robust fusion framework that integrates fine-grained depth supervision and channel-wise attention mechanisms. Combined with a temporal multi-frame mechanism, our framework effectively mitigates issues caused by dust occlusion and misidentification. We validated our method's detection accuracy on a self-constructed mining road dataset, achieving 89.6% mAP, surpassing BEVFusion's 88.3% mAP. Tests on sensor occlusion and failure further demonstrated its robustness in adverse conditions typical of unstructured road scenarios. © 2024 IEEE.

Aimed to the challenge of robotic voice interaction, this study leverages ChatGPT (chat generative pretrained transformer) technology to develop a humanoid robot solution with a central processing system. Employing a top-down design approach, the solution encompasses the design of voice, video, and motion streams between users and the robot, enabling voice communication and expression output. By integrating hardware devices and a central control system, the entire humanoid robot system achieves a twofold purpose. On one hand, it combines data from conversational context, user tone and emotion, and user facial expressions to appropriately exhibit expressions. On the other hand, it formulates reasonable voice responses in conjunction with extracted statement content and emotional cues. Lastly, two physical prototypes of the humanoid robot are constructed. Experimental trials are conducted to assess the voice conversation and expression output capabilities of the humanoid robot, thereby confirming the rationality and effectiveness of the proposed solution. © 2024 IEEE.

Rapid urbanization and global warming significantly impact tidal dynamics in the Pearl River Estuary, China

Due to the dual impacts of anthropogenic disturbances and climate change, tidal hydrodynamics of estuaries have been intensively investigated for their potential to increase flood risk and devastate coastal habitats and human communities. Climate change leads to rises in sea levels, which can amplify regional tides and increase tidal ranges. This study takes the estuarine area of the Pearl River (PRE), one of the fastest-developed estuaries in China, as an example to explore the effects of land cover changes and sea level rise on tidal dynamics. Annual mean tidal levels were collected at 26 major hydrological stations from five major rivers/waterways. To better understand the temporal changes in tidal levels, we analyzed the trends and periodic patterns through linear regression and Complex Morlet wavelet analyses. For the main Pearl River outlet, where conversion of agricultural land to urban use had been primarily taking place, the tidal level changes were significantly affected by increased built-up areas and decreased cultivated land areas. On the other hand, in the middle to upper reaches of the Xi River and Shunde-Hengmen Waterway, we observed decreased tidal levels with decreases in the agricultural lands. No significant correlations were found between annual mean tidal levels and land cover changes downstream of the main rivers. Instead, the tidal level changes at locations close to the coastline were more related to sea level rise, with an average of 0.002 m per year increase. This study highlighted the importance of human activity and sea level rise impacts on tidal dynamics. A systematic understanding of the tidal changes in the estuary is expected to help enhance mechanisms of estuarine hydrology, which could serve as the basis for improving the management and practice of coastal regions in coping with climate change and estuary protection. © 2023
