"Maneuverability characteristics of ships with a single-CPP and their control during in-harbor ship-handling"
Hideo YABUKI
 Video and Slides in 1window | Video Only | Video and Slides in different windows << Jan 20,2010 up
It is well known that a controllable pitch propeller (CPP) can provide smooth speed control. On the other hand, in case of ships with a single CPP and a single rudder, an unstable yaw moment is often exerted which introduces a significant reduction in maneuverability during the coasting maneuver with the propeller pitch feathered to zero and the stopping maneuver. This lecture deals with the maneuverability characteristics of ships with a CPP and their effective control during in-harbor ship-handling. The results of full-scale experiments using a 5,884 G.T. training ship to investigate the above characteristics and of a simulation study using the MMG type mathematical model to develop effective control methods of CPP ships are presented.

"Economic analysis of the formation of global alliance in shipping and airline industries and its impact on markets from the viewpoints of industrial organization"
Nobuaki ENDO
Video and Slides in 1window | Video Only | Video and Slides in different windows << Jan 20,2010 up
This lecture provides an economic analysis of the formation of global alliance in shipping and airline industries and its impact on the markets from the viewpoints of industrial organization. First, it examines the changing nature of regulatory framework for corporate behaviors in both industries. In shipping industry, competition policy toward shipping conference has been enhanced. In airline industry, the U.S. government and European Union have been promoting liberalization. Second, it discusses economic benefits of the global alliances and their impact of corporate performance. Third, the lecture evaluates monopoly power following the formation of the global alliances in the two industries by employing the Panzar-Rosse H statistics as well as conjectural variation.

"Marine Culturology"
Akifumi IWABUCHI
Marine culture or ocean culture implies the distinctive ways of life by which human beings adapt themselves to the aquatic environment. Marine culturology is an integrated and transdisciplinary academic subject to research upon marine culture itself with holistic approach. The subject is composed of four sub-fields: marine anthropology, marine history, underwater archaeology, and the study of maritime art. Marine anthropology being the nucleus of marine culturology has excelled other fields in studying, in particular, maritime communities. Marine history or a new marine historical view based upon the sea has emerged since the latter half of the 20th century in place of a traditional maritime historical view based upon the land. Underwater archaeology reconstructs human cultural activities of the past from material remains under the ocean in order to trace bygone social facts over the sea. Studying maritime art such as ocean painting or marine literature under the name of marine culturology is to open up an enrichment of human cultural and artistic developments. Traditionally, politics or economics tends to cut the ocean as barrier into many territorial waters, but marine culturology could integrate it into one united contact zone of culture and civilization over the national boundaries.

"Basic GPS Positioning"
Nobuaki KUBO
Video and Slides in 1window | Video Only | Video and Slides in different windows
This lecture has been prepared for a short course on GPS positioning, with particular reference to sea and land-based applications. This consists of three chapters: Introduction to GPS, GPS applications and Future GNSS (Global Navigation Satellite System). Although GPS is one of GNSS, GPS is still playing a very important role of satellite positioning system. By learning GPS, you will be able to grasp the outline of satellite positioning system. Since marine and land applications will continue to use GNSS, this lecture will be a good opportunity to study GNSS. I will introduce several good textbooks for further study in the last of my lecture.

"Surface circulation of the North Pacific Ocean"
Fumiaki KOBASHI
Video and Slides in 1window | Video Only | Video and Slides in different windows
The ocean moves all the time at various temporal and spatial scales with different driving mechanisms. This talk focuses on basin-scale ocean surface movement that is described as currents and gyre circulation. First I briefly overview features and similarities of surface circulation among the world oceans, and then explain the dynamics of oceanic currents and the wind-driven theory by which the existence of most of surface currents can be explained. In the latter part of the talk, I refer to a strange current named ¡Èsubtropical countercurrent" that flows eastward along 19o-26oN in the North Pacific, in opposition to the westward flow expected from the wind-driven theory, and show how the countercurrent is generated. In addition, the influence of oceanic currents on the overlying atmosphere, which is one of the most exciting recent topics in oceanography and meteorology, will be explained.

"Friction noise caused by fretting and its prevention"
Tatsuhiro JIBIKI
Video and Slides in 1window | Video Only | Video and Slides in different windows
Fretting may be accompanied by friction noise and preventing or reducing it can be important not only for designers and operators but also for engineering. In this lecture, the mechanism of the friction noise under dry conditions and grease-lubricated conditions during fretting would be described with a combination of the measuring of the electrical contact resistance and the phenomenon observation of the generation of the friction noise, direct observation of the fretted surface, and also a vibration analysis of the friction noise. In addition, as its prevention method, the effect of "shot peening" on the prevention of the friction noise would be represented at first, and next, the effect of the "surface micro texturing" such like "dimple pattern" or "crossed groove pattern" would be mentioned.
