ESTIMATION OF ROOFTOP AREA AND POTENTIAL AREA FOR ROOFTOP GREENING IN TOKYO METROPOLITAN AREA

Identifying Potential Area and Financial Prospects of Rooftop Solar Photovoltaics (PV)

In an urban area, the roof is the only available surface that can be utilized for installing solar photovoltaics (PV), and the active surface area depends on the type of roof. Shadows on a solar panel can be caused by nearby tall buildings, construction materials such as water tanks, or the roof configuration itself. The azimuth angle of the sun varies, based on the season and the time of day. ...

High Assurance System for the Tokyo Metropolitan Area Railway Network

L Introduction Large-scale public systems in today’s information control field require. that seveml conditions should be satisfied. Fmt, a phased-in construction of the system must be possible so that the system can be constructed over a long period of time. Second the system must be flexible and be adapted to meet the changes of social needs. All such systems are assumed to constantly grow, ex...

Estimation of Turbulent Diffusivity over the Tokyo Metropolitan Area from Constant-volume Balloons

In order to study the characteristics of turbulent diffusion over an urban area, constant-volume balloons with transponders were released at altitudes of 200 and 400 m, and their behavior was observed over the Tokyo Metropolitan area. The atmospheric diffusivities are derived from the Lagrangian properties of the balloons, in relation to the temperature lapse rate and the turbulent intensity. T...

Adaptive search area for fast motion estimation

In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...
