On my presentation: This time, I didn’t get to check the slides with either Yagi-sensei or Noguchi-sensei. However, given that I have presented this research 2 times (practice and official presentation at JSCE 2022), I had a little more confidence in it. In this presentation, even though the theme was the same as in the JSCE 2022, I wanted to have a different approach. While the JSCE presentation focused on the mechanics and calculations, this time, I shifted the focus to flow phenomenon descriptions. I tried to keep everything visual-driven and I think it really worked. In my experience from the audience seat, presentations at conferences are like marketing for the papers. If you tell a good and interesting story, people will go to the paper to find out more. I think there is no need to jam so much into a 10 – 12-minute presentation. I also managed to keep the time. I finished at the 11th-minute mark, so there was plenty of time for questions. I received 3 questions from the floor during the Q&A session, and a lot more during the coffee break. I was looking for critique/ideas to improve or expand our work but there wasn’t much.
On the content of the symposium: One thing that I truly appreciated from the symposium was that it got me closer to the practical engineering side of the field. I was very impressed by one presentation by Dr. XXXX, in which he presented about the vibrations of the dampers on the cables and how useless they were because of poor placement. Dr. XXXX also had a very charming sense of humor, which he showcased throughout his speech. I always think academia is, most of the time, unnecessarily stuffy and formal. I’m glad that I am not the only one who thinks so. On the second day, Prof. OOOO presented a keynote lecture on axial flow structures on an inclined/yawed cable. The topic was near and dear to me. She presented a lot of fascinating results which I think can be potentially incorporated into our future paper on yawed cables. It seems “big data” and “machine learning” is the real buzzword recently. However, I was surprised to see no one address it in the symposium. In fact, I noticed a sense of resentment in most of the participants regarding the application of AI algorithms to engineering problems. There was one keynote lecture by Prof. TTTT where he stated that an engineer should be responsible for his/her judgment, and not because “the computer says …”. I do agree with this. However, I don’t think being shy away from AIs is the way to go. For so many hundreds of years, we have been refining our understanding of physics, and we sure still have a long way to go. However, big data is there not to replace physics, but to assist us in decision making. So why not? On this approach, I am thinking of branching out to optimization algorithms and incorporating them into aerodynamics. It can be closely related to the management/operation/health monitoring side. I remember Yagi-sensei did mention that data from the bridge with two different types of cables is being collected. If we can access such data, it can be a very valuable resource for new research topics. I may discuss with Yagi-sensei later about this.
