26 November 2021, Discharge of treated Fukushima nuclear accident contaminated water: macroscopic and microscopic simulations has been published on National Science Review, which is a full affirmation of the students and teachers of the subject group who are generous and rigorous in their learning! NSR officer micro-push high-quality and efficient, reflecting China's outstanding leading journals of the super-class level! Thanks to the director of singhua University's Institute for Ocean Engineering (IOE), Zhang Jianmin's guidance and support, thanks to the editorial department and reviewers for their high evaluation!

The results of this study are of great significance for the prediction of long-term spread of pollutants, the rational response of nuclear wastewater discharge plans and the monitoring of subsequent radioactive material concentrations. In the future, we will continue to deepen our research, Further explore the long-term impact of the discharge of nuclear waste water on the whole ocean and mankind, and provide important decision support for the country and the world to deal with the nuclear wastewater crisis!

Note: National Science Review , whose impact factor in 2021 is 17.275, is the top journal in the multi-discipline domain. For more information, please see the introduction video.

Thesis: Ontology-based multi-source heterogeneous O&M data integration framework for tunnel structural health assessment has been published in the journal Structure and Infrastructure Engineering.

As a typical representative of infrastructure, tunnels are indispensable carriers for the normal operation of cities, with their safe and efficient operation directly influencing urban efficiency. However, the various data supporting tunnel operation and maintenance (O&M) exhibit significant diverse sources and structural differences, which pose substantial challenges to tasks such as tunnel structural health assessment. To address these challenges, this paper proposes an ontology-based multi-source heterogeneous O&M data integration framework to support the assessment of tunnel structural health, thereby improving decision-making efficiency in tunnel maintenance. The framework consists of four layers: data layer, ontology layer, mapping layer, and application layer, enabling the unified modeling, integration, and comprehensive application of multi-source heterogeneous tunnel O&M data. Additionally, the proposed framework is applied to a practical engineering project, the Tanglang Mountain Tunnel. Compared with existing methods, the framework demonstrates improvements in data fusion accuracy, data completeness, and operational efficiency.

Note: Structure and Infrastructure Engineering is a journal in the field of engineering technology in the Q2 zone, with an impact factor of 2.6. The first author of the paper is Liu Longxiang, a master's student, and I am the corresponding author. The research results were funded by the National Key Research and Development Program of China .

On June 14th, the research group held a team-building activity aimed at bidding farewell to the graduating students and enhancing the team's cohesion at the same time.

This team-building activity was carefully planned and rich in content. At the beginning of the event, the members participated in an immersive live-action theater murder mystery game, engaging in team reasoning and competition among four camps, fully demonstrating their wisdom and spirit of collaboration. The evening dinner party was filled with a warm and lively atmosphere, interspersed with interactive games including those about teamwork and fun challenges, with laughter and joy never ceasing. At the end of the event, the graduates shared their unforgettable experiences in the team and expressed their gratitude. Everyone also presented them with graduation blessings and gifts. I also delivered a brief speech, thanking everyone for their hard work and expressing my beautiful expectations for the future development of the team.

This team-building activity not only relaxed both the body and mind but also strengthened the bonds among the members. The event concluded successfully with a group photo as a memento. The research group wishes the graduates a bright future!

The citation count of "Web-oriented BIM 3D Viewing and Information Management" on China National Knowledge Infrastructure (CNKI) has reached 100 times.

BIM Server provides a solution for BIM to support construction life cycle. Currently , the structure of BIM Server is C/S, but gradually B/S also shows its advantages. The release of the HTML5 standard brings the WebCL technology which supports hardware graphics acceleration in browser and is one of a series of revolutionary Web technologies. Thereby the foundation is laidfor achieving Web-oriented BIM infomation management and 3D display of BIM model. In this paper, the model information scope and its expression of Web-oriented BIM is ana-lyzed, and the corresponding information management technology and the BIM model display based on the Three. js, which is a WebCL framework, are studied. Then, a WebCL-based platform for 3D display and information management of BIM is also developed. Application shows that the graphics platform of the platform performs stable with nice rendering for large BIM. Meanwhile the platform provides rich feature supports for Web client by favorable interactive functions, showing a great application value.

Journal of Information Technology in Civil Engineering and Architecture was founded in 2009. It is a national first-class journal sponsored by the China Graphics Society and under the supervision of the China Association for Science and Technology. Wang Hengwei is the first author of the paper. The other authors include Associate Researcher Lin Jiarui and Professor Zhang Jianping from the Department of Civil Engineering at Tsinghua University.
