Abstract

fetched live from OpenAlex

This work shows the results obtained when compairing the account in emergy, in Thermoeconomy and in an economic analysis of energy farming energy systems. The goal of this study is to assemble in an unique work three different ways of attributing costs, considering their restrictions and indexes. Three configurations are compaired: the first one uses an energy generation system installed in a sugar-ethanol plant in So Paulo. The second operates with a generator fed with biogas from a biodigestor of cattle manure that is integrated to the plant.The third system operates with a generator that receives pig slurry that is also integrated to the plant. The goal of quantifying the emergy on these systems, the thermoeconomic and the economic analysis in to make possible a wide view about the implications on these integrations.It is shown that when the biosystems are integrated, using their residual biomass as an input to electricity generation, the electricity cost is reduced. The methodology of this work makes possible seeing three aspects of the biosystems: the environmental sight by emergy, the inner thermodynamic sight given by the first and the second thermodinamic laws by the thermoeconomy and the investor sight that presents the economic financial results of the biosystems' integration.

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.
