Our lab members contributed in the KKHTCNN conference in Campus Plaza in Kyoto, Japan. Many researchers from several universities participated in the conference presenting their current progress in various research topics. We presented different topics related to the recent researches conducted in the lab. The venue of the conference was in Kyoto, the old capital of Japan which is famous for the remarkable food, beautiful weather and the colourful autumn, not to mention the spectacular historical landmarks. The topics I am personally interested in were presented in the Construction engineering track, which was very interesting because it is related to building information modelling. After our lab members presented, they were asked few interesting questions by the audience which opened our eyes for numerous different approaches that can be used to improve the researches and exchange many ideas towards further methodologies. Students and professors from Korea, Singapore, Taiwan, Thailand, and China also attended the conference, we made good connections with them over dinner and it was very interesting, i personally enjoyed their company.

In the closing ceremony, we enjoyed Sushi, Steak and delicious dessert while talking to other students from different universities. In the ceremony, there was also The best presenter award from each university.

Attendees: Prof. Kim, Shinya Kimura (Ph.D. candidate), Takuya Mimasu (M2)

12th JGBS is the 12th Japanese-German Bridge Symposium, a biennial event which alternates between Japan and Germany. Researchers and engineers from Japan and Germany share their studies and interests about bridge structures over two days. This symposium includes 10 keynote lectures and 69 technical presentations. From our laboratory, three members participates, and Mr. Kimura and I presented our researches. His title is “Analytical Investigations on Traffic-Induced Low Frequency Sound Radiated from Bridges”, and my title is “Feasibility investigation on damage detection of a real bridge by means of FE model updating”. In this symposium, various topics focusing on bridge structures were presented and discussed, so we could learn a lot of knowledge in bridges. Also, I got motivation from good presentations delivered by other students. After the symposium, we attended an excursion of 12JGBS, which is a technical tour to visit some construction sites of bridge structures in Germany. That was the first time I’ve visited and seen the construction sites of bridge structures, so I’ve learned and experienced so much on the excursion. I would like to appreciate Prof. Kim and our laboratory giving a good opportunity and support to me.

From August 28 to August 31, I participated the JSCE (Japan Society of Civil Engineers) Annual Conference and attended the 20th International Summer Symposium. I delivered my presentation Long-term vibration and temperature monitoring on a steel plate girder bridge in the session CS2, in which topics on structural engineering and earthquake engineering were discussed in English. Interestingly, many of the talks were associated with structural health monitoring and damage detection, including damage detection of the pre-stressing tendon, tire force estimation and analysis of mechanical behavior of bridge with ruptured cables. Different from the conference I attended in Qingdao, China in July, the discussions were fairly earnest and the questions were proposed in a pragmatic perspective. In another session that I attended, where topics of geotechnical engineering were discussed, one of the audience, who is a senior member in the field, praised the parameters including pile ratio presented in one of the presentations and said it was the first time for him to see such design in his 30 years’ career. I was moved by the scene where I felt that the decent engineer's spirit was inherited. Among all the talks, the work done by Xiao-fan Wang from The University of Tokyo really raised my interest. Her research was related to system identification of a small-scale timber frame. When the mass matrix was assumed to be a diagonal matrix, an illogical result was obtained (the mass matrix is not positive-definite); then she ‘relaxed (smoothed)’ the non-positive matrix and made it a non-diagonal mass matrix, the identification presented sensible and ideal result. Though being simple and basic, I found it demonstrated the rationality of physical model built of mathematics. Besides all the intensive discussions, Sapporo in Hokkaido is a beautiful place to travel and I indeed enjoyed the seafood there. It is really upset that the strong earthquake just happened there. I do hope the people and infrastructure in Hokkaido would recover soon from the disaster.

From August 29th to August 31st, I joined in the JSCE (Japan Society of Civil Engineers) Annual Conference in Hokkaido University in Sapporo. The campus was beautiful and has many engineers from all over the world. I wanted to take this opportunity to meet different engineers from different fields and countries to share ideas and indulge in fruitful discussions. Since my Japanese language proficiency is not enough to attend the lectures given in Japanese, I only attended the lectures given in English as well as our lab team members lectures. I attended a lecture covered by Student member Lazarus Lemi Chacha Costa from Shibaura Institute of Technology about The technological transfer in construction industry from developed countries to developing countries. This lecture took a case study of Japan and South Sudan and how the developing countries need to realize the significant change happening in the construction industry to be able to achieve the economic growth it needs. The lecturer showed the significant difference between methods of construction in both countries and how knowledge transfer is vital to the safety of people. After the presentation there was a brief discussion about the issues in both countries and how sometimes it’s hard to apply the Japanese methods in developing countries due to the lack of funds and/or resources. Another lecture that I really enjoyed was presented by Graduate student Ali Gurkan from Istanbul Technical University about the challenging on construction method and management under the Nurol life project in Istanbul, turkey. The lecturer explained the problems faced during that project in terms of cost, quality and social acceptance and how the land price affected the construction method and materials used. After the lecture Mr. Ali and I had a brief discussion about the management side of construction in turkey, and I was surprised how similar the situation is to Egypt as most of the private clients prefer having a foreign consultants than having local ones.

Lectures aside, I really enjoyed Hokkaido and Sapporo’s scenery, food especially the Misu-based Ramen and Jengis Kan Mutton meat. On the 6th of August a strong earthquake hit Sapporo resulting in massive damages to the infrastructure as well as losses in human lives. My condolences to the families of the deceased and I hope Hokkaido can recover from the aftermath of this disaster.

From July 15 to August 5, we participated in ‘‘2018 Asia-Pacific-Euro Summer School on Smart Structures Technology (APESS-2018)’’, which was held at Qingdao University of Technology (July 15 - 27) and Harbin Institute of Technology (July 28 - August 5). During July 23 to 25, we also attended the 7th World Conference on Structural Control and Monitoring (7WCSCM), where 17 keynote sessions and more than 500 conference presentations were delivered, including two of them from our lab given by Dr. GOI Yoshinao and M2 student MA Xinda.

The theme of the summer school consists of ‘Knowledge’, ‘Practice’, ‘Culture’, and ‘Friendship’. We were given lectures about the state-of-art techniques of smart structure, took technical visits to long-span bridges and high-speed railway vehicle workshop, joined sightseeing to places of interests in the two cities (we even watched Peking Opera rehearsal in Harbin), conducted experiments of on-site vibration test and system identification, active control, and also acoustic wave emission; furthermore, we managed to complete a group project of crack detection based on computer vision technique. Altogether, more than 35 lectures were given by experts in structural dynamics, active and passive control, machine learning, and other cutting-edge structural health monitoring techniques, from which we learned a lot about the latest research; also thanks to the arrangement of technical visits (e.g. subway construction site) and sightseeing in Qingdao and Harbin, which enable us to experience the culture and development of civil engineering in China in an immersive way.

During the last three weeks, we spent quite a lot of time with members in the summer school (especially those in our group), who were from different countries around the world: America, China, Ecuador, Egypt, Germany, Italy, Japan, Korea, Mexico, Mongolia, Vietnam and Saudi Arabia, etc. They were all so kind and we indeed had a great time together. This is one of the most precious experiences in the summer school.

Thanks to the lab, we really appreciate that we were given the opportunity to join such a meaningful activity, in which we broadened our horizon of the development in our area, communicated with our peer from both academic institutes and the industry around the world, and last but not least, such experience simply made us more motivated in research and our lives.

IABMAS2018 is the 9th International Conference on Bridge Maintenance, Safety and Management. In this conference, researchers and engineers in the field of bridge maintenance and management discuss their various topics and enhance each other. I presented a research entitled “System identification of a bridge by a sparse-like system matrix”. In this session, a great discussion in a part of Q&A was done by experts having high knowledge and motivation, so that it was a great learning opportunity. However, I could not answer exactly as I thought in the session. I again realized enough my inadequate English skill, but fortunately during lunch time after the session, some experts and Ph.D. candidates came to me to discuss my research topic, so I could discuss with them and obtain some feedbacks and suggestions regarding my study. To attend this international conference was a very good experience for me. I was excited and motivated by great presentations and great discussions. I would like to appreciate prof. Kim and our laboratory giving a good opportunity and support to me. Also, I would like to make my effort to do my research very hard!!

On June 30th (Sat.), after the 3rd General Meeting we had a lot of fun in the GYOZA（餃子）party celebrating Dr. GOI's promotion to the position of Assistant Professor.

On April 28th, the welcome party for B4 students was held at Kawaramachi. We enjoyed our time and discussions with the new lab members.
