After generating the surface, the height of these known points can be subtracted from the generated surface to examine how closely the new surface represents the true surface. These differences can be used to c
Understand change using multiple comparative maps; perform image classification, image interpretation, and map algebra to calculate change. Sample: What is the current status of the electric grid, and how are changing weather conditions affecting field crew safety? Integrate real-time data to react ...

This enabled us to calculate the accuracy of the classification of the C4.5 algorithm in relation to the dataset as a ratio between the correct classified RFPCs (into the diagonal of the matrix) and all of the RFPCs [58]. The matrix rows include the RFPCs in an actual class, whereas ...
The Kriging surrogate model was established to calculate the response variable [S.sub.s], and this model replaced the operation of TOUGH2/ECO2N and reduced the simulation time to increase the efficiency of the Sobol sensitivity analysis method [27]. Global Sensitivity Analysis to Assess Salt Preci...
