In this paper, our research objective is to develop a database virtualization technique so that data analysts or other users who apply data mining methods to their jobs can use all ubiquitous databases in the Internet as if they were recognized as a single database, thereby helping to reduce their workloads such as data collection from the Internet(More)
It is our purpose to develop a novel fin type of microrobot in pipe that has the characteristics of flexibility, driven by wireless, good response and safety in body. This paper proposes a novel fin type of model microrobot utilizing electromagnetic actuator as the servo actuator to realize moving motion for biomedical application. We also discuss the(More)
The earthquake with the seismic center around the coast of Miyagi Prefecture and the oceanic trench of southern Sanriku is expected to occur with high probability. Enforcement of comprehensive anti-tsunami measures is expected with high emergency in the Sanriku region across Miyagi and Iwate Prefecture. Consequently, a system is required that prefectures,(More)
In recent years, business modeling has attracted attention in the development of information systems for analyzing and designing the working procedures of the system under development. The paper concentrates upon the use of business modeling in the process of analysis from the point of view of early identification of procedural bottlenecks. It goes on to(More)

In this study, we conducted long-distance radio propagation experiments at 1mW/145 MHz to realize low-power long-distance communication for wildlife research and disaster prevention telemetry [1]. We successfully realized long-distance communications from a weather balloon (elevation: ~14,000 m) with 1 mW radio power. Furthermore, we demonstrated that our(More)
We conducted long distance radio propagation experiments at 1-10mW/145MHz, to realize a low-power long-distance communication for wildlife research and disaster prevention telemetry. In this paper, we describe that we succeeded in long distance communications, from a ferryboat to the top of Mt. Asugiyama (elevation: 501m, distance: 15km) in Kure, Hiroshima,(More)
