Optimizing Spatial Sampling on Stratified Non-homogenous ... (Nov 24, 2010)
Spatial sampling is an important and frequently used method in investigating spatially distributed physical attributes, such as regional temperature, environmental pollution, cultivated land, organic material in soil, and so on. Traditional sampling methods...
Spatial and Temporal Evaluations of Disinfection By-produ... (Nov 22, 2010)
To some extent, the municipal water disinfection process itself introduces contaminants (in the form of organohalogen compounds) into the water supply. This is of interest because several disinfection by-products, such as trihalomethanes (THMs) and haloacet...
Method to Construct Fuzzy Membership Functions for Digita... (Nov 2, 2010)
Fuzzy membership function is an effective tool to represent relationship between soil and environment for digital soil mapping. Usually construction of a fuzzy membership function requires knowledge on soil-landscape relationships obtained from local soil e...
Upscaling gross ecosystem productivity to the landscape s... (Oct 25, 2010)
Growing interest in climate change has stimulated recent research that aims to quantify components of the natural carbon (C) cycle. The eddy-covariance technique (EC) is commonly used to directly measure the CO2, water vapour and energy exchange between the...
Differentiation of Soil Conditions over Low Relief Areas ... (Oct 21, 2010)
In many areas, such as plains and gently undulating terrain, easy-to-measure soil-forming factors such as landform and vegetation cannot be effectively used in digital soil mapping. A challenging problem is how to develop a new environmental variable that c...
Prediction of soil properties using fuzzy membership values (Oct 20, 2010)
Detailed information on the spatial variation of soils is desirable for many agricultural and environmental applications. Prof. ZHU A-Xing, Institute of Geographic Sciences and Natural Resources Research (IGSNRR) and his group explored three approaches that...
