Abstract
This thesis examines the performance of a residential cogeneration system based on a Stirling engine fueled by diesel and biodiesel. An energy balance test is performed for each fuel and the energy, exergy, and marginal efficiencies are calculated. Particulate emissions are measured using a direct sampling device that enables collecting the particles on a filter for gravimetric analysis. The total unburned hydrocarbons are measured using a flame ionization detector. A Fourier transform infrared spectrometer is used to measure the concentration of carbon dioxide, carbon monoxide, nitric oxide, nitrogen dioxide, water, methane, acetylene, ethylene, formaldehyde, and acetaldehyde emissions in the exhaust. A comparison is made between the performance of this system and other residential cogeneration technologies such as internal combustion engines and fuel cells.

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
