Health Monitoring of High-rise Building with Fiber Optic Sensor (SOFO)
Mikami, Takao,Nishizawa, Takao Council on Tall Building and Urban Habitat Korea 2015 International journal of high-rise buildings Vol.4 No.1
Structural health monitoring is becoming more and more important in the domain of civil engineering as a proper mean to increase and maintain the safety, especially in the land of earthquakes like Japan. In many civil structures, the deformations are the most relevant parameter to be monitored. In this context, a monitoring technology based on the use of long-gage fiber optic deformation sensor, SOFO is being applied to a 33-floors tall building in Tokyo. Sensors were installed on the $2^{nd}$ floor's steel columns of the building on May 2005 in the early stage of the construction. The installed SOFO sensors were dynamic compatible ones which enable both static and dynamic measurements. The monitoring is to be performed during the whole lifespan of the building. During the construction, static deformations of the columns had been measured on a regular basis using a reading unit for static measurement and dynamic deformation measurements were occasionally conducted using a reading unit for dynamic measurement. The building was completed on August 2006. After the completion, static and dynamic deformation measurements have been continuing. This paper describes a health monitoring technology, SOFO system which is applicable to high-rise buildings and monitoring results of a 33-floors tall building in Tokyo from May 2005 to October 2010.
The Way to Make Student Project Activity Successful
Takao Hanabusa,Masaki Konishi,Satoshi Kiriyama 한국공학교육학회 2014 공학교육연구 Vol.17 No.5
Student independent project activity is beneficial for enhancing many kinds of abilities, e.g., team working, collaboration,communication, presentation, creativity, leadership, and so on. More than ten project teams actively perform every year in the Centerfor Innovation and Creativity Development of The University of Tokushima. The project management workshop was planned in order tomake project activity successful. In this workshop, the team members studied the importance of holding a common objective amongthem and of making a clear plan for achieving the activity. They practiced brainstorming method and KJ method and experienced a PDCAcycle. The team activity will be fruitful on the basis of the project management method.
THE AKARI PROJECT: LEGACY AND DATA PROCESSING STATUS
TAKAO NAKAGAWA,ISSEI YAMAMURA 한국천문학회 2017 天文學論叢 Vol.32 No.1
This paper provides an overview of the AKARI mission,which was the first Japanese satellitededicated to infrared astronomy. The \textit{AKARI} satellite was launched in 2006, and performed both an all-sky survey and pointedobservations during its 550 days in the He-cooled mission phases (Phases 1 and 2). After the He ranout, we continued near-infrared observations with mechanical cryocoolers (Phase 3). Due to a failureof its power supply, AKARI was turned off in 2011.
Complex Network Theory and Agent-Based Modeling
Takao TERANO 한국경영과학회 2016 한국경영과학회 학술대회논문집 Vol.2016 No.10
In this talk, I will present a new model of micro-macro social learning model for a classical economic problem “the emergence of money”. We propose Doubly Structural Network (DSN) Model, which consists of one global social network of agents and internal networks that represent agents’ recognition. DSN model enables us to describe the emergence of proto-money as a self-organization process of the common recognition of exchangeability. We conduct an analytical method and a numerical approach into bifurcation phenomena of a new mean-field dynamics derived from this DSN Model. The main contribution of the paper is summarized as follows. (1) The proto-money can emerge from commodities without distinctive properties. (2) The social network degree is a definitive factor for non-/single-/multiple-emergence of proto-money. (3) The variance of the social network degree (existence of hubagents) also affects emergence of proto-money.
