Prof. Zhaoyuan Yu was invited to attend the 2018 International Graphics Conference

At the invitation of Professor Nadia Magnenat Thalmann, Chairman of the International Graphics Conference, 2018, Yu Haoyuan, Zhou Liangchen, and Hu Di traveled to Singapore and Indonesia on June 10, 2018 to participate in the International Graphics Conference in 2018, and made a report entitled “The Application of Geometry Algebra in the Frontier of GIS” and “The Expression of Hierarchical Network MVTree Based on Geometric Algebra Subspace”,As the representative of the 2018 ENGAGE Workshop Organizing Committee, Prof. Yu Zhaoyuan presented the best thesis (theory) and the best paper (applied) award to Stephane Breuils of Paris East University and Adam Leon Klepp of Norwegian University of Science and Technology.

The 2015 graduate student successfully completed the thesis defense

On May 24th, three students from the labs Zhu Shuai, Yuan Shuai and Shi Gege respectively gave a thesis defense on the ‘Hierarchical Construction and Analysis Method of Road Networks Based on Geometric Algebra ’, ‘ynamic Evacuation Method of Multi-targets under Scene Constraints based on Geometric Algebra’, and ‘Geometric algebra expression and analytic method of geography object semantics’ conferences in the 23rd conference room of the Academy of Sciences. All the students passed the assessment smoothly.
