Abstract

fetched live from OpenAlex

Surface Magnetic Resonance Sounding( MRS) has become increasingly popular as a new geophysical technique to detect the groundwater directly. It will be actual significance to use this method in the detection of groundwater ahead of mining or tunneling face. Since the loop size is severely restricted in underground strait condition, it was brought forward that the multi-circle vertical coil can be used to detect the presence of water in whole space. The equations of excited field numerical and the MRS sounding formulation of vertical coil were carried out for whole space. According to changing loop size,circle number,the coil's placing angle and the geomagnetic inclination,the result of the MRS sounding for one model were simulated,and correctness of the results of numerical simulation was verified by field experiment. We gained the conclusions: the larger of the loop size or circle number is,the larger of the maximum of the initial amplitude of MRS sounding is,coil for horizontal or vertical rotation has little effect on the initial amplitude of MRS sounding,but the excitation pulse moments need be adjusted to the rotating angle for the max amplitude detection; the larger of resistivity is in stratum,the superior of detecting effect is; as the detecting depth increases,the maximum value of the initial signal amplitude decreases,and at the same time,the excitation pulse moments increase with the detecting depth increasing.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
