Case Studies on The Use of LiveLink for MATLAB for Evaluation and Optimization of The Heat Sources in Experimental Borehole

“…This simplification was used in all the case studies (see Section 3.1); neither the effect of variable percentages nor different compositions of the rocks were considered in the evaluation. The structure and geometry of the heat collector itself (i.e., the "Pershing" system) are given in [23] and Figure 1; within data preprocessing, the paper also describes mutual interactions between this structure (where all negative heat sources may be included) and the respective measured input data from the chambers and data from the evaluation points [see Figure 2 and Equations (10) to (14)], which is beneficial. Let us add that in Figure 2, the particular stages of processing the data (i.e., "preprocessing", "processing", and "post-processing") are clearly marked.…”

“…[10] gives a summary of redeveloped localities within Ostrava (for example, the Hrabůvka dump in Ostrava-Hrabůvka, the Zárubek mining dump in Ostrava-Kunčičky, the railway embankment in the site of the Moravian chemical plant in Ostrava-Mariánské Hory, the isolated burning body of the railway embankment in the Heřmanice dump in Ostrava-Heřmanice) and close surroundings (for example, the Vrbice dump in Bohumín-Vrbice). [14] also introduces the redeveloped locality outside the Moravian-Silesian region (for example, the Krimich dump in Tlučná in the Pilsen region).…”

“…Q 1 to . Q 4 (W) are evaluated based on Equations (10) to (14); see also Figure 2. Their representation come either from measured data in chambers (i.e., sources .…”

“…Research on burning mining dumps not only aims at localizing centers of fires but also at identifying crucial environmental contaminants and other environmental risks. Finally, the survey also focuses on the use of burnt-down tailings such as in the construction industry (see [14]).…”

“…Tables 6 and 7). Without correction, this case study was not the optimal solution (see above) due to the higher sensitivity of the model to estimates of temperature differences in Equations (11) and (14) when considering the validity of Equation (10).…”
