Research relating to the sea-keeping quality of fishing vessels |
|
Related instructor(s): Seiichi TAKEDA |
|
Outline: |
This research in conducted as a topic of research for doctor's students in their doctor's program. Using types of small fishing boat designed with the experiential knowledge of former fishing operators and boat builders, students carry out quantitative evaluations of these boats via model and full-scale tests, to research the characteristics of such aspects as hull appendages intended to improve sea-keeping quality in ocean waves. |

|
Outline: |
This research observes the phenomena on the ocean, and the motion of ships and marine structures that respond to those phenomena, from the perspective of a nonlinear dynamical systems and the complex system related the nonlinear dynamical systems. The complex systems exhibit a diverse range of behaviors and functions including overall self-organization, chaos, and memory learning, due to the large-scale interaction of its constituent factors and its nonlinear nonlinear nature. This research analyzes the phenomena on the ocean and identifies the systems of the ship motion and marine structures that respond to the phenomena. This is carried out from the perspective of elucidating the principles behind complex system behavior and structures, analyzing the massive amounts of data created by complex systems and selecting usable data from that, and designing systems that adapt to these complex systems. |

Research relating to the stability of small fishing boats |
|
Related instructor(s): Seiichi TAKEDA |
|
Outline: |
This research topic investigates stability in small fishing boats of less than 20 gross tonnage, boats which do not applicable the stability regulations, by conducting measuring experiments on full-scale. This research allows students to understand the factors required in ensuring the safety of operating boats and safe working procedures for fishing operators. This research is carried out as a topic of research for students in their master's course. |

Research relating to over-sea broadband usage on small sea-going boats |
|
Related instructor(s): Seiichi TAKEDA |
|
Outline: |
This research is conducted as a joint research project with a commercial manufacturer and aims at realizing the real-time bi-directional high-speed communication of large volumes of data, including video image data, in communications between the land and sea vessels. The research is investigating and evaluating the development of a system installed on a small boat that has significant ship motion when traversing ocean waves. |
