Thus, knowledge graphs are promising models to represent knowledge and have been widely built, e.g., YAGO [25], Freebase [26], Probase [27], and DBpedia [28]. A geographic knowledge graph is a domain knowledge graph that is in the exploratory stage. At present, most geographic knowledge...
Measuring the relative sensitivity of the statistical methods with respect to the quality of the dependent variables, sampling strategy, size and type of the probability map, and the validation process used to evaluate the predictive capability of the models. d. Developing hybrid methods for handling...
As the gap between what the science seems to say is necessary in the near future and the reality of polluting and unhealthy transport systems grows, so does the need for transparent models that stand up to scrutiny and enable participation and informed debate. This has been well documented in...
More conservative estimates (using equally plausible models) suggest this won’t happen before 2043. Given the stress on our southern oceans caused by other human factors such as climate change and pollution, the 54 per cent threshold may require re-evaluation. Either way we are ...
Influence of resolution on other variables:Gao [26] explored the correlations between spatial resolution and root mean square error (RMSE), spatial resolution and accuracy, as well as spatial resolution and mean gradient in the context of digital elevation models (DEMs). He concluded that (i) ...
In 2004 MINEQ completed R&D work of two new models of quarry shovels. EKG-1500R (rack shovel) has dip- per capacity of 18 cubic meters (with detachable dippers of 15 to 25 cubic meters) and EKG-1500K (rope shovel) has dip- per capacity of 26 cubic meters (with detachable dippers ...
