Top left: on top of a bus; bottom left: on top of a tram; top right: attached to a solar-powered weather station on a building; and bottom right: attached to a smartphone. Sensing is an important part of computational sustainability, where evidence are collected about important environmental phenomena that are not ...

The purpose of this study was to evaluate the spatial changes of groundwater phosphate concentrations using geostatistical methods based on data from 10 groundwater wells. One of the conventional tools in decision making on the groundwater management is geostatistical method. To evaluate the spatial changes of phosphate concentrations in groundwater, the universal kriging method with cross-vali...

HTML5 is being developed as the next major revision of HTML (Hypertext Markup Language), the core markup language of the World Wide Web. It aims at reducing the need for proprietary, plug-in-based rich Internet application (RIA) technologies such as Adobe Flash. The canvas element is part of HTML5 and is used to draw graphics using scripting (e.g., JavaScript). This paper introduces Cartagen, a...

In recent years, the frequent fouling accidents have posed a serious threat to people’s life and property safety. Owing wide distribution of pollution sources variable meteorological factors, it is very time-consuming labor-intensive task map using traditional methods. this work, study on mapping based satellite remote sensing carried out in Yunnan Province, China, as an example. Several machin...
