Abstract

fetched live from OpenAlex

The constant volume combustion apparatus, known as the Ignition Quality Tester (IQT T M ), is increasingly used around the world to measure the ignition delay (ID) of compression ignited fuels, and to calculate the derived cetane number (DCN ) from correlations developed with the cetane number (CN).The IQT is widely used in research due to its I would like to express my gratitude and appreciation to my supervisor professor Edgar A. Matida.His continuous support and guidance have demolished the difficulties toward gaining my PhD.I would like to acknowledge the Advanced Engine Technology (AET) Ltd. for allowing me to use their facilities and dedicating an IQT to do my research.The AET staff was wonderful and generous in providing everything for my research.I must thank Mr. Gary Webster, the principal of the AET for the opportunity to work in his laboratory, may he rest in peace.I also want to appreciate the unlimited technical support during experimental work from Luc Menard, Omar Ramadan, Dave Gardiner

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
