Congratulations to Wu langtao passed in the Department of Civil Engineering of Tsinghua University Master's thesis!

The thesis is entitled "Knowledge  Management with Knowledge Graph Based on AEC Text". Based on the massive specification text data in the industry, this study proposes an automated method to construct a large-scale knowledge graph in the field of engineering construction safety management, and further designs a whole-process management scheme for safety auto-compliance knowledge. An example was demonstrated in the safety management of the Zhongshan-Jiangmen Expressway reconstruction and expansion project.

The building of party style and clean government is always on the road, and persistently upholding the correct style and discipline is always on the road. Studying and implementing Comrade Xi Jinping's important thinking on strictly administering the party, strengthening party building, and making strict party management a new normal are important issues currently facing all of our party members.

On April 24, the party branch of the Institute for Ocean Engineering (IOE) organized a special education meeting on "exercise full and strict governance over the Party", which was attended by all party members and activists of the branch. Teacher Zhu Xiaoshan, secretary of the branch, presided over the meeting online, and led the study of special content.

At the meeting, I led everyone to conduct systematic study from the five aspects of the background, important documents, connotations, results and experience of exercise full and strict governance over the Party, and combined with the cases of colleges and universities, let everyone always feel that the comprehensive and strict management of the party is around.

Adhering to the principle of "exercise full and strict governance over the Party" is a "military order" made by the party to the people, and the IOE will resolutely fulfill its commitments with actions and greet the victory of the party's twentieth national congress with excellent results.

Operability analysis of SWATH as a service vessel for offshore wind turbine in the southeastern coast of China has  published online in Ocean Engineerin.

SWATH (Small Waterplane Area Twin Hull) vessel is introduced as a novel application as SOV to be deployed off the coast of southeastern China, an investigation into the operability for walk-to-work (W2W) on-site service using the new type of vessel is conducted in this study. The operability of service operation vessels (SOV) is highly concerned with the cost, schedule, and weather window to the operation and maintenance of offshore wind farms. In this paper, The features of SWATH’s motion behavior are discussed by performing a seakeeping analysis, which is compared to a similar size monohull SOV. The limits of W2W and other operating conditions are then modeled and analyzed by the numerical method established in the frequency domain. The results show that SWATH has excellent operability as well as the robustness against arbitrary wave heading. Finally, The fuel consumption under the high sea-state shows higher usage compared to the monohull by a qualitative estimation using the second-order mean drift forces. When the damping is insufficient, the optimization of SWATH geometry and proper damping device may help further improve the operability by suppressing resonant heave and roll.

Note: Ocean Engineerin belongs to the top of the field of engineering and technology magazine, with a 2021 impact factor of 3.795. Associate Professor Li Binbin of The Tsinghua Shenzhen International Graduate School is the first author and co-corresponding author of the paper.

Epidemic prevention is not slack, scientific research does not stop, tsinghua SIGS research group teachers and students are making full use of online resources to do scientific research. At the same time, I am very grateful to the Graduate School for publicizing our research group. (See this link for details)

During the epidemic period, the research group adopted the mechanism of "one-two-three-four" and "two-place double drive" to carry out scientific research activities. Among them, "one" is to insist on a weekly group meeting, "two" is to ensure communication with the two students, and "three" is to solidify and promote the three-level guidance. The "fourth" is to actively strengthen the cooperation between the four sides. Under the impetus of this mechanism, the research group studied and scientific research in an orderly manner, and the students also actively reported on the recent work progress, and the results were good.

I believe that by the end of the epidemic, it will be a clear sky and a bright sun. My students and I will continue to make great strides...
