  • As the web is vast and disorderly, it is difficult to find desired information on the web. In particular, finding image resources (knowing where and what kind of images can be found on the web) is very difficult but challenging. As the first step towards the web resource mining, this paper reports the preliminary results of collecting a number of images by a web robot as well as presenting those meta information.

  • When we search information on the Web using search engines, they only analyze the text information collected from the source files of Web pages. However, there is a limit to analyze the layout of a Web page only from its source file, although Web page design is the most important factor for a user to estimate a page. In particular it often happens on the Web that the pages of similar design ofter similar information. We propose a method to analyze layout for comparing the design of pages by treating the displayed page as image.

  • Here we evaluated the effect of using water retentive pavement or WRP made from fly ash as material for main street in a real city block. We coupled computational fluid dynamics and pavement transport (CFD-PT) model to examine energy balance in the building canopies and ground surface. Two cases of 24 h unsteady analysis were simulated: case 1 where asphalt was used as the pavement material of all ground surfaces and case 2 where WRP was used as main street material. We aim to (1) predict diurnal variation in air temperature, wind speed, ground surface temperature and water content; and (2) compare ground surface energy fluxes. Using the coupled CFD-PT model it was proven that WRP as pavement material for main street can cause a decrease in ground surface temperature. The most significant decrease occurred at 1200 JST when solar radiation was most intense, surface temperature decreased by $13.8^{\circ}C$. This surface temperature decrease also led to cooling of air temperature at 1.5 m above street surface. During this time, air temperature in case 2 decreased by $0.28^{\circ}C$. As the radiation weakens from 1600 JST to 2000 JST, evaporative cooling had also been minimal. Shadow effect, higher albedo and lower thermal conductivity of WRP also contributed to surface temperature decrease. The cooling of ground surface eventually led to air temperature decrease. The degree of air temperature decrease was proportional to the surface temperature decrease. In terms of energy balance, WRP caused a maximum increase in latent heat flux by up to $255W/m^2$ and a decrease in sensible heat flux by up to $465W/m^2$.
