Falsifying the existing theories of geometric stability

I believe that I am heading in a good direction to falsify existing theories for determining geometric stability of complex frames.

If it can be drawn at least one structural frame whose stability cannot be explained by existing theories, it means that they are falsified and a room for new theories is opened.

On my way in trying to falsify existing theories of geometric stability of complex frames, I have drawn three complex frames (orange, cyan and brown) whose geometric stability, I believe, are complicated or even impossible to explain by existing theories.

If someone thinks that he/she can give answers and explanations on whether the three complex frames are geometrically stable or unstable, please contact me with solutions.

Thank you!

We have published an Original Research Article in the Journal of Hydrology: Regional Studies (Impact Factor 3.645), with topic entitled “Modelling typhoon-induced extreme river discharges: A case study of Typhoon Hagibis in Japan”. Our proposed methodology and findings are helpful for development of tools for Early Warning System real-time forecasts of extreme rainfall-induced flash flood water levels and discharges. The Article is Open Access.

Publication: Frontiers in Marine Science

We have published an Original Research Article in the Frontiers in Marine Science (Impact Factor 3.661), with topic entitled “Dynamical Downscaling of Coastal Dynamics for Two Extreme Storm Surge Events in Japan”. Our modeling approach is helpful in understanding and assessing shoreline changes and damages on the associated coastal aquaculture and applicable for climate change impact assessment, in which context it can ultimately serve as a guideline for developing adaptation policies. The Article is Open Access.

New: Research Interests (Let’s Think)

I added a new Tab “Research Interests (Let’s think)” on the top menu, where my research interests are described in five categories: (1) Hydrology, (2) Coastal and Ocean Engineering, (3) Biophysics (Biohydrodynamics), (4) Structural Mechanics and (5) Psychology. Each of these research interests are explained in more details, with references to my past contributions and calls for possible collaborations from the particular research interest.

Award: RDT Silver Prize

It is my honor to be awarded with RDT (Regional Design Team) Silver Prize in the “Contest for Sharp and Brilliant Ideas” by Hiroshima University. I hope my ideas will serve to realize a prosperous, bright future and vision for Higashi-Hiroshima City.

JCCE 2019 (Kagoshima): Delivered a talk

I delivered a talk in the Japan Society of Civil Engineers (Coastal Engineering, JCCE) at 23 of October 2019. I enjoyed having many interesting discussions with colleagues as well as field trip to the DPRI Sakurajima Volcano facility. It was my first time ever being close to a volcano.

AOGS 2019 (Singapore): Delivered a talk

I delivered a talk in the Asia Oceania Geoscience Society (AOGS) conference from 28 July to 2 August 2019 in Singapore. I had many interesting discussions including with my ex coworkers from Kyoto University and several new colleagues from Hiroshima University. I gained a great new experience in the conference.

ICWRER 2019 (Nanjing): Delivered a talk

I delivered a talk in the International Conference on Water Resources and Environment Research (ICWRER) from 14 to 18 June 2019 in Nanjing, China. The conference was a great experience to me, I listened to many interesting talks and discussed about potential future research collaborations.



JpGU 2019 (Tokyo): Delivered 2 Talks

I participated in the Japan Geoscience Union Meeting 2019 from 26 to 30 May 2019 in Makuhari Messe, where I delivered two talks. I enjoyed interacting and discussing with other researchers, including many of past co-workers from Kyoto University.

  1. Downscaling and Reanalysis of Coastal Current System on the Ibaraki Coast with Included Freshwater Impact
  2. Storm Surge Response to Freshwater Outflow from Typhoons on the Ibaraki Coast
