On March 15, the national key research and development plan "urban sustainable Development key technology and equipment" key special project "building and municipal public facilities intelligent operation and maintenance theory and method" project launch meeting and implementation plan discussion meeting was held in Beijing. Mr. Sun Xinzhang, Deputy Director of the Office of Strategic Studies and Regional Development of China Agenda 21 Management Center, Academician Huang Wei of Southeast University, Academician Peng Yongzhen and Academician Du Xiuli of Beijing University of Technology and other 8 project consulting experts attended the meeting.

The project consists of 4 subjects. Professor Zhang Lianzhen from Harbin Institute of Technology, as the project leader, reported the overall situation of the project to the participating experts. The participating experts fully affirmed the theoretical innovation and overall implementation plan of the project, and believed that the project has urgent social needs, outstanding innovation and great significance for research and development. Meanwhile, they demonstrated the key issues of the project and the subject, and put forward constructive opinions and suggestions.

I served as the person in charge of project 2, "Rapid Holographic Sensing and multi-source heterogeneous data Fusion for Intelligent operation and Maintenance of buildings and municipal public Facilities", and reported to the experts attending the meeting about the research background, research content and task decomposition, technical scheme and implementation plan, expected results and organizational guarantee, etc. Ma Lin, Associate Professor of Harbin Institute of Technology, Ren Zhengru, Assistant Professor of Tsinghua Shenzhen International Graduate School and other members of the research team also participated in the meeting.

On March 4-5,  the Eighth National BIM Academic Conference was successfully held in Qianhai Cooperation Zone, Shenzhen.

Professor Ma Zhiliang from the Department of Civil Engineering of Tsinghua University organized and attended the meeting as the chairman of the BIM special committee. Assistant researcher Lin Jiarui presided over the plenary meeting and I attended the meeting. My doctoral students Min Yantao and An Peng gave an oral report to share in the sub-conference.

As a major international exchange event for the coordinated development of science and technology in Guangdong-Hong Kong-Macao Greater Bay Area, this conference has enhanced the mutual understanding and interaction between members and industry colleagues, and built an efficient "connectivity bridge" of digital city information resources.

"Three-dimensional Dynamic simulation and visualization Method of Sea Waves" has been awarded the invention patent certificate (patent number: ZL202211436973.0).

The invention discloses a three-dimensional simulation method for sea surface wave motion. Based on the analysis and simulation of the change of the shape and position of the sea surface, the process of wave movement can be divided into two sub-processes: elevation change and horizontal movement. For elevation changes, three-dimensional grids are obtained based on fixed horizontal grids and sea level elevation function mapping, and the direction calculation method of top point method is given to realize smooth surface display of sea waves. For horizontal movement, a color change method based on mapping and moving speed of water quality points is proposed to realize the display of water flow in the horizontal direction. Based on the proposed simulation method, the invention also realizes a three-dimensional wave dynamic simulation device, which consists of five modules, namely horizontal grid generation, three-dimensional vertex management, point method direction calculation, map coordinate updating and result display, which can support the three-dimensional dynamic visualization of sea waves in various forms.

Compared with the existing technology, the invention can be applied to the three-dimensional dynamic simulation and visualization of various types of waves including measured waves, regular waves and random waves, and can support the division of horizontal grids in different ranges, different precision and complex situations. It has good scalability, and provides an efficient, reliable method and convenient tool for the simulation of sea waves. It provides a foundation for the application of information digitization and visualization in Marine industries such as Marine ecological environment, Marine engineering, Marine transportation and so on.

Note: The inventors of the patent also include doctoral students Liu Yi, Academician Zhang Jianmin and Associate Professor Li Binbin.

On February 9, the Winter vacation social practice detachment of Tsinghua University visited the Institute for Ocean Engineering  to carry out exchange activities. The detachment consists of 55 undergraduates majoring in civil water conservancy and ocean engineering, energy and power engineering, aerospace engineering, theory and applied mechanics, etc.

The detachment was divided into three groups and visited the engineering pool laboratory, the digital twin laboratory (our research group) and the gas hydrate laboratory located in the Ocean Building. Teachers and members of the Institute for Ocean Engineering  explained the visiting group. Afterwards, the teachers and students of the Institute had a discussion and exchange with the members of the detachment. I presided over the exchange meeting and introduced the history and development orientation of Shenzhen International Graduate School and Institute for Ocean Engineering. The detachment held in-depth discussions with the teachers of the Institute on such topics as cooperation and development, national needs and future trends of ocean engineering, college talent training and social responsibility, hoping to further establish a more long-term and more common communication mechanism to promote the exchange and academic cooperation between teachers and students in Beijing and Shenzhen.

The successful holding of the winter vacation social practice exchange, let students further contact with society, understand society. I hope students can exercise themselves in practice, close to the society with practical actions, dedication to society!
