Abstract

fetched live from OpenAlex

The Marnoch heat engine (MHE) is a new type of heat engine currently under development at the University of Ontario Institute of Technology. The MHE can use waste or collected heat at temperatures that are currently unusable or not economically viable to use by conventional technologies. The MHE operates by using a heat source to heat the air in one heat exchanger and cool the air in another. This creates a pressure difference. This pressure difference drives a two-way piston connected to a flywheel. A generator connected to the flywheel converts the mechanical energy of the flywheel into electricity. This thesis presents a simulation of the current MHE prototype. The simulation is designed to be easily customized to allow it to model the performance of future possible MHE installations and predict their performance. The simulation is shown to accurately model the performance of the MHE prototype by running under conditions similar to those found in the lab, and comparing its results to collected data from the prototype. Simulations were also run to show the model’s ability to model possible applications with different operating conditions and physical components.

Full frame distilled prediction

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.
