"Web-oriented Dynamic 3D Visualization of Construction Processes" has been published in the journal of Construction Technology.

Aiming at the problems such as difficult to update, limited software environment or non-dynamic existing 3D visualization methods of construction processes, this paper proposes a web-oriented 3D dynamic visualization method of construction processes based on Cesium, including relative data models and animation definition, and a rapid 3D animation generation method based on frame segmentation and integration approaches. An efficiency test proves that the performance of frame segmentation and integration algorithms can meet the needs of general animation of construction processes. Besides, the above method is applied to show a case construction process on the web and to support online editing, playing, and updating of the process step animation, which verifies the feasibility of using the method in actual projects.

Simulation Analysis of the Dispersion of Typical Marine Pollutants by Fusion of Multiple Processes has been published in the journal Sustainability.

The rapid development of coastal economies has aggravated the problem of pollution in the coastal water bodies of various countries. Numerous incidents of massive-scale marine life deaths have been reported because of the excessive discharge of industrial and agricultural wastewater. To investigate the diffusion of typical pollutants after discharge, in this study, a multi-process fusion simulation analysis model of pollutants under the action of ocean currents was established based on the concentration analysis method. Furthermore, key technologies involved, such as the parameter value, data selection, and visualization, were investigated. The iterative analysis and programming realization of three independent sub-processes, such as pollutant diffusion and transport, and the drift path and concentration distribution of pollutants after their discharge into the sea, were visualized. The case study revealed that the increase in the concentration of pollutants in the ocean was affected by the diffusion sub-process, and the transport sub-process plays a critical role in the long-distance transport of pollutants. The proposed method can provide technical support for marine environmental risk assessment and dynamic tracking of marine pollutants.

Note: Sustainability is an important journal in the field of environmental science and ecology and a core journal in Q2, with an impact factor of 3.9 in 2023.

A digital twin-based framework for simulation and monitoring analysis of floating wind turbine structures have been published online at Ocean Engineering.

It is currently a prevailing trend to adopt clean energies instead of traditional ones due to the global climate change caused by carbon emissions. Offshore wind farms, in particular, have emerged as a crucial source of renewable energy, owing to their benefits such as no land occupation and abundant resources. However, the design, installation, operation, and maintenance (O&M) of floating wind turbines (FWTs) involve multiple sources of heterogeneous data, which pose challenges to data integration and management, as well as to the simulation and analysis of FWTs. To address this issue, this study proposes a unified framework based on digital twin (DT) to acquire and integrate diverse types of information used throughout the entire life cycle of FWTs. A digital 3D model serves as a medium to enable real-time synchronization and inversion of sensor data, facilitating the simulation and analysis of the global state of FWTs. The proposed framework is evaluated through a case study of a twin-barge float-over project, which includes process simulation, mechanical analysis, and anomaly identification. The results demonstrate that DT can facilitate timely monitoring and analysis of FWTs, and enable visualization of construction plans, early warning of structural abnormalities, and accurate recognition of FWT posture and marine environment. The case study validates the efficacy of the proposed framework in ensuring personnel and equipment safety, optimizing project plans, and improving construction efficiency.
