Abstract
The ever-growing oil and gas industry has led to the high demand for technologies which accurately sense defects in underground pipelines. Radio frequency identification (RFID) based sensors are a hot topic for use with buried pipelines because they do not require batteries and are low-cost. The issue is most RFIDs do not function well in the presence of metals especially magnetic carbon steel pipes that are prevalent in the Oil and Gas industry. Higher frequency RFIDs in UHF range also attenuate rapidly through different soil compositions. In this work, a comparison between conventional full/half duplex (FDX/HDX) and sequential (SEQ) RFID systems in the VLF and LF bands is detailed. Measurements comparison between the two communication systems in the presence of ASTM A-53 carbon steel pipe show a SEQ RFID system offering 8.3 dBm (6.76 times) improvement over the conventional FDX/HDX system.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
