From July 2nd to 20th, 2022, the "Mechatronics Design Evaluation and Optimization" Postgraduate Summer International Workshop was successfully held, which was funded by the Graduate School of Zhejiang University and hosted by the School of Mechanical Engineering of Zhejiang University. Professor Klaus Janschek of the Institute of Automation, School of Electrical and Computer Engineering, Technische Universität Dresden was invited as the main teacher of the project. Associate Professor Zhu Xiaocong of the School of Mechanical Engineering of Zhejiang University hosted the workshop. The workshop consisted of 18 lessons, including students' self-introductions, lectures, practical training, group discussion reports, etc., which enabled the students to have an in-depth understanding and practice in producing scientific research reports, modeling stochastic signal, system simulation and optimization. During the cultural exchange, better understanding of each other was acquired.
On July 2nd, the workshop activities officially began. Associate Professor Zhu Xiaocong welcomed Professor Janschek to bring the summer project to everyone, and then Professor Janschek introduced his research direction, personal experience and the relevant situation of Technische Universität Dresden in detail. Then the students introduced themselves in turn, not only expounding their personal research interests, education and academic experience, showing the excellent personal style of Zhejiang University students, but introduced the colorful culture and characteristics of their hometown. The wonderful and interesting self-introductions was praised by Professor Janschek, who also said that he also had a broader understanding and understanding of Chinese culture and looked forward to the next trip to China.
From July 4th to 8th, Professor Janschek gave a series of reports on the theme "Stochastic Signal Modeling and Simulation". By asking students to think about the three characteristics (peak, root mean square and power spectral density) of noise that often occurs in scientific research, Professor Janschek inspired the students to understand the characteristics of stochastic signals. Elaboration on the spectral representation, modeling, simulating and analyzing of stochastic signals using Matlab/Simulink was also provided. Subsequently, through practical training, the students demonstrated the results of stochastic signal modeling and simulation in the form of scientific reports, and actively discussed the similarities and differences between theoretical analysis and practical implementation. Thus, a deeper understanding was reached.
On July 6th, Professor Janschek gave a special lecture on how to make a good scientific presentation. From the aspects of preparing, content planning, audience analysis and speech style, he analyzed and explained the precautions when making scientific reports. Key points were demonstrated on the spot. From the comparison of PPT before and after modification, the students deeply understood the key points of making a good scientific report. It was a great help for students in making reports on research work in the future.
From July 15th to 19th, Professor Janschek brought a series of lectures on system performance evaluation and optimization. The concept of stochastic system performance measurement, calculation and optimization was introduced. On the basis of knowledge on stochastic signal metrics which was mentioned before, system metrics budgeting and optimization design with multiple interference or input was elaborated. Although the subsequent practical training was more challenging than the first one, students prepared carefully and finally presented a correct understanding of the theory and the proficiency of the software. The discussion was warm and the harvest was full.
On July 20th was the last lecture of this summer workshop. The lecture was about an overview of German culture bathed in a relaxed and pleasant vibe. Professor Janschek came to the courtyard of his house and introduced the class his pet puppy Poli. After that, nine students presented in groups on different themes including introduction of Dresden, history of Saxony, scientists and musicians in Germany. During the presentation, Professor Janschek talked to the class warmly and was pleasantly surprised by the unique insights presented by students. Professor Janschek then led the students on a virtual city tour in Dresden, during which he vividly introduced the history, culture, ancient and modern celebrities of Dresden and Saxony. The superior educational condition and beautiful living environment of the Technische Universität Dresden were also introduced. At last, Professor Janschek welcomed everyone to visit Dresden at any time.
The workshop ended with an online group photo of teachers and students. During the workshop, students actively participated in discussions and carefully prepared presentations. They say, Professor Janschek explained the knowledge about stochastic system to everyone with absolute professionalism, which was a great benefit. In addition to technical knowledge, skills on making scientific reports, a valuable experience of cultural exchange was obtained. Most importantly, Professor Janschek's meticulous attitude towards scientific research and his work set everyone a great example.
