The so-called Brain-Circulation Program will be over at the end of March, 2015. Thus for the purpose of providing younger researchers who were dispatched overseas for international collaborations with a chance to introduce and explain their activity results in the style of research presentation, we organized a symposium on March 18-19 at the library hall of Science and Engineering Library, Suita Campus of Osaka University. As keynote speakers, we invited Professor Pierre Ferrant from ECN in France and Professor Odd Faltinsen from NTNU in Norway; they also gave presentations on the recent development in the research associated.
　On the other hand, with approval and financial support from MEXT (Ministry of Education, Culture, Sports, Science & Technology, in Japan), we have just started the International Program of Maritime & Urban Engineering in the graduate course of Global Architecture especially for overseas students from October, 2014. In this special program, all lectures and research direction are being conducted in English. Thus in order to provide the students in this program with the information on internationally high-level and cutting-edge research, the symposium was organized as a joint symposium; in which we wish the students were enlightened to study hard with big ambition of becoming future leaders in the world. Although the Brain-Circulation Program will be finished at the end of this fiscal year, there were large outcomes so far in this program, such as creation of international academic network, nurturing international experience and leadership, and enhancement of research ability of younger researchers. We wish sincerely that they will be the real leaders of the next generation and will be active further in the arena of research and education.
　Continuing from last year, an organized session (OS) on Fluid-Structure Interaction Analyses was planned and implemented on November 21, 2014, at the Autumn Meeting of JASNAOE (Japan Society of Naval Architects and Ocean Engineers) held in Nagasaki. Same as last year, this OS was chaired by Professor Kashiwagi (Osaka University) and could be a good chance for an interim report of the activities in the Brain-Circulation Program. Dr. Pierre-Emmanuel Guillerm also came from ECN, France, for this meeting and gave a presentation on the progress of joint research being conducted with Osaka University. There were five other presentations in the session, which includes the papers by Kazuhiro Iijima (Osaka University) and Kazuki Ikushima (Osaka Prefecture University). It might be natural that all overseas dispatched researchers should have reported their research progress in this OS, but it was impossible because Hidetaka Senga (Osaka University) and Kenji Sasa (Kobe University) are still staying at NTNU, Norway. All presentations and subsequent discussions in the session were conducted in English, which could show a leadership and new direction in internationalization of the JASNAOE. Many people participated, although this OS was arranged during the last time zone in the 2nd day of the technical program. A snap shot of related members is shown below, which was taken using a mobile phone at the corridor in a hectic time of clearing the session rooms away.
　Professor Pierre Ferrant of ECN, France, stayed at the Department of Naval Architecture & Ocean Engineering for two weeks from the end of September, 2014, as Specially Appointed Professor of Osaka University for a part of activities in the “International Collaboration Promotion Program” supported by Osaka University. Furthermore, Dr. Pierre-Emmanuel Guillerm could come to Osaka by extending his itinerary for attending an international conference held in Kuala Lumpur in Malaysia. By taking these opportunities, the 30th Hydro-Seminar was organized on October 3rd (Friday) as concentrated special lectures. Professor Ferrant explained the state and efforts at ECN for internationalization of the graduate school, whereas Dr. Guillerm gave a presentation on some experimental results for a bottom-mounted offshore wind-energy platform being conducted as an international collaboration in the Brain-Circulation Program. In this seminar with special lectures, many of newly-enrolled students at International Program of Maritime & Urban Engineering participated, and we were honored in that a vice president of Osaka University, Professor Aimoto, also joined the lecture of Professor Ferrant.
　At present, four researchers, Hidetaka Senga (Assistant Professor of Osaka University), Kenji Sasa (Associate Professor of Kobe University), Kazuhiro Iijima (Associate Professor of Osaka University), and Kazuki Ikushima (Assistant Professor of Osaka Prefecture University), are staying at NTNU in Norway as a part of the brain-circulation program. Moreover, a memorial celebration seminar in honor of 70th birthday and academic contributions of Professors Odd Faltinsen and Torgeir Moan, who are important partners in our international collaboration, was held at NTNU on 19th and 20th in May. In consideration of these situations, we organized the "brain-circulation research seminar" at NTNU in Trondheim on May 16 (Friday) to hear the progress, results, and future strategy of the research from overseas staying young researchers dispatched by the brain-circulation program. This seminar started with introduction of the brain-circulation program, followed by the presentations by five young researchers including four persons staying at NTNU (Senga, Sasa, Iijima, and Ikushima) and Hirotada Hashimoto (Associate Professor of Kobe University). Then Professor Carl Martin Larsen of NTNU explained his own former and present researches. Furthermore, Eiichi Kobayashi (Professor of Kobe University) and Masahiko Fujikubo (Professor of Osaka University) explained some topics taken out of the latest researches related to the brain-circulation program.
　The technical program of this research seminar was sent in advance to the graduate students and researchers of NTNU by e-mail. However, there were few graduate students, because the midst of May was a busy season for students due to examinations and also they were busy with preparation of Professor Faltinsen-Moan celebration seminar. Nevertheless, some researchers at NTNU participated and joined in the discussions and thus the seminar was fruitful. Since the sun was still located high in Trondheim after 5:00 when this seminar finished, we took commemorative photos with all Japanese participants, and then enjoyed viewing the city of Trondheim and taking dinner at EGON restaurant in the observation tower (broadcast tower) near NTNU. Next day (May 17) was the bicentennial anniversary after the Norwegian constitution establishment, and the atmosphere of celebration was wafting also in the city of Trondheim.
　The International Workshop on Water Waves & Floating Bodies (IWWFB) is highly rated in the field of wave-body interactions and free-surface hydrodynamics and hence every year many prominent researchers participate. The 29th IWWWFB was hosted by Professor Kashiwagi of Osaka University and held from March 30 (Sunday) to April 2 (Wednesday) in 2014 at Hotel Hankyu Expo Park in Suita, Osaka. There are some fundamental principles in this Workshop: (1) The program will be in the single session, implying that the number of papers to be presented is limited to 50 or at most 55, the selection of which is made by the selection committee of IWWWFB. (2) Attendance is restricted basically to the authors who have submitted extended abstracts, regardless of whether they are accepted or not. (Exceptions may exist for sponsors, the past hosts, and session chairpersons.) (3) Since participants stay at the same hotel and take lunch and dinner with all other participants, they can enjoy conversation from morning to night.
　Therefore, all participants can listen to all the presentations. Moreover since there are many prominent researchers, the level of presentation and discussion is relatively high. Although this circumstance may give a feeling of tension to younger Japanese researchers, at the same time all participants can recognize their researches, and aspiration and strong motivation can be acquired through listening to the presentations by other persons or ample talking with participants.
　Hirotada Hashimoto (he moves to Kobe University as Associate Professor from April 1) and Kenji Sasa (Associate Professor of Kobe University) who are two of the young researchers in our brain-circulation program also participated in this IWWWFB and made their presentations. They enjoyed this Workshop and I believe they had good stimulus and experience. Kenji Sasa returned temporarily from NTNU for attending this Workshop, but he left for NTNU again immediately after the end of the Workshop. Incidentally, the homepage of this 29th IWWWFB is the following: http://iwwwfb2014.naoe.eng.osaka-u.ac.jp/ This homepage describes the above-mentioned fundamental principles, all abstracts of the papers, technical programs and so on. The hosts of 2015 IWWWFB are Dr. Richard Porter of Bristol University and Dr. Jun Zang of Bath University in UK.
　Professor Pierre Ferrant of ECN (Ecole Centrale Nantes) in France which is an important overseas partner of our brain-circulation program was invited to the Department of Naval Architecture & Ocean Engineering, Osaka University as a Guest Professor. In order to introduce research activities at LHEEA (Laboratoire de Recehrche en Hydrodynamique, Energetique et Environnment Atmospherique) of ECN, he gave a lecture on "Numerical Simulation and Model Scale and Full Scale Testing of Marine Renewable Energy System". Many graduate students (especially foreign students in the English special course) participated, and the lecture including questions and discussions lasted 2 hours or more in a friendly atmosphere. Professor Pierre Ferrant's visit to Japan was realized through the "international joint research promotion program" which Osaka University is supporting. He is scheduled to stay at Osaka University periodically during the international joint research promotion program. After the lecture, we had an informal social gathering, and we spent pleasant time together with Emeritus Professor Shigeru Naito, Visiting Professor Robert Latorre, graduate students, and office personnel.
　Professor Kashiwagi (Osaka University) who is the representative of our brain-circulation program organized a session on Fluid-Structure Interaction Problems at the 2013 Autumn Meeting of the Japan Society of Naval Architects and Ocean Engineers held on November 21 to 22 in 2013. In this session, six papers regarding fluid-structure interactions were presented; which could be an interim report of the research being done by Kazuhiro Iijima (Osaka University), Hirotada Hashimoto (Osaka University), Kazuki Ikushima(Osaka Prefecture University) and others who are overseas dispatched younger researchers in the brain-circulation program. This session greatly attracted attention of the participants in the meeting, and could be a good opportunity to let them know activities of the brain-circulation program. Moreover, Dr. Pierre-Emmanuel Guillerm (ECN, France) also participated and intensive discussion was performed. In addition, partly because of his participation, presentations were mostly conducted in English including subsequent discussions, and this organized session also could be an opportunity to show a new way of activating the society annual meeting. 　The 27th Hydro-Seminar was held at 15:00-17:30 on Wednesday, November 20 in 2013. In this Hydro-Seminar, Dr. Pierre-Emmanuel Guillerm of LHEEA (Laboratoire de Recehrche en Hydrodynamique, Energetique et Environnment Atmospherique) of ECN (Ecole Centrale de Nantes, France) was invited as a part of activities of our brain-circulation program. He is a research counterpart of Iijima during his staying at ECN with support from the brain-circulation program. With the title of "Research Activities Dedicated to Renewable Marine Energy at LHEEA Laboratory", he gave a lecture on the research of various marine renewable energies (including the wave, current, and wind energies) which is being conducted in LHEEA, for roughly one hour. There were approximately 50 participants including Professor Kashiwagi (Osaka University), Associate Professor Iijima (Osaka University), Professor Fukasawa (Osaka Prefecture University), many staffs and students. In addition to Dr. Pierre-Emmanuel Guillerm, Prof. Ching-Yeh Hsin (National Taiwan Ocean University) gave a lecture on "The Computations of Forces and Flow Fields of Wind Turbines and CurrentTurbines" and Prof. Jiahn-Horng Chen (National Taiwan Ocean University) gave a lecture on "Marine Energy Test Site in Taiwan". We had many discussions on each presentation and thus the scheduled time has run out easily.
　　 　I attended the 32nd International Conference on Ocean, Offshore and Arctic Engineering (OMAE) in 2013 held from June 9 through 14, 2013 in Nantes, France. This international conference is held every year by the American Society of Mechanical Engineers, and this year it was held in Nantes, and the representative of the local host was Professor Pierre Ferrant of ECN (Ecole Centrale de Nantes) which is an important overseas partner in our brain-circulation program.
　Since the main concern in the latest ocean engineering field was placed on the development and utilization of ocean energy, the number of participants in the OMAE Conference tends to increase and it was about 1,200 this year. Although there were many paper presentations regarding the marine renewable energies, the main purpose of my participation was to attend and present a paper at the Symposium in honor of Professor Odd Faltinsen at NTNU (Norwegian University of Science and Technology) who is an important overseas partner in the brain-circulation program. Professor Eiichi Kobayashi of Kobe University (the domestic researcher in the brain-circulation program) also participated in this international conference. I met young researchers dispatched to ECN, Mr. Hirotada Hashimoto (Assistant Professor of Osaka University), and Mr. Kazuhiro Iijima (Associate Professor of Osaka University) staying at ECN now and performing joint research. The friendship was deepened during the meeting with Professor Pierre Ferrant, ECN, Professor David Le Touze, and Professor Odd Faltinsen, NTNU (see photograph). The joint research at ECN in the brain-circulation program looks progressing to favorable condition now, and a part of the research was presented by Mr. Hirotada Hashimoto (though most was performed at Osaka University). This OMAE Conference could be a good opportunity to let others know about the brain-circulation program through exchange of the information with many attendees during the recess and lunch time etc and to know the recent international research level in fluid-structure interaction problems. Incidentally the detail of this 32nd OMAE Conference can be referred to at the below URL: http://www.asmeconferences.org/OMAE2013/. The venue of the 33rd OMAE Conference will be in San Francisco, USA.
　This workshop was organized for the purpose of information exchange concerning the latest research results in Japan and France on the hydrogen and wind energies. A report here is concerned only with the part of wind energy (Part II) which is closely related to our interest.
　The wind-energy workshop was held for the purpose of exchanging the information on the latest trend of Japan and France in the field of the wind, current, and wave energies, or the ocean thermal energy conversion OTEC (Ocean Thermal Energy Conversion). The responsible person in charge was Professor Patrick Chedmail (Director of International Industrial Partnerships of Ecole Centrale de Nantes, Representative of France Energies Marines). As listed below, the contents of the workshop covers broad area including actual enterprise, policy, financial support, research activities in the wind energy of both countries. Moreover, announcement was also made of "Renewable energy exhibition 2013" to be held in Tokyo Big Sight from July 24th to 26th in 2013. About 50 persons participated in this workshop from Japan and France.
　After the workshop, a reception was held in the residence of French ambassador. Not only workshop participants but also many other important persons attended, such as Ambassador France, President of Renault, Governor of St-Nazaire county, Mayor deputy of Nantes, and Chair of chamber-of-commerce Nantes St-Nazaire. My attendance was realized by recommendation of Professor Pierre Ferrant of Ecole Centrale de Nantes. I had a talk with Prof. Arnaud Poitou (Director of Ecole Centrale de Nantes - AUDENCIA group representative) and Prof. Bertrand Alessandrini (Director of Development at the Ecole Centrale de Nantes), regarding the cooperative relation with ECN in our brain-circulation program.
