Abstract

fetched live from OpenAlex

Diver propulsion vehicles (DPVs) are used by recreational and military divers. For the latter divers there is a need for special DPVs which have low magnetic and acoustic signatures so that they can operate in areas were mines are known or suspected to exist or dumped munitions. The possibility of constructing a power system for such a DPV was investigated. Since commercial off-the-shelf (COTS) products are being used increasingly in military systems a survey and evaluation of existing power systems technologies was conducted. One of the most viable options identified was the use of a Stirling engine. As part of the military specification was the use of a liquid hydrocarbon fuel it was necessary to explore ways in which the necessary oxidant could be provided, using a commercial product, if possible. In the latter case the use of oxygen candles was identified as a viable option. Thus, a Stirling engine system was designed and a breadboard unit constructed and experimental studies of a COTS oxygen candle were conducted. It was determined that such a combination of oxygen source and energy convertor was worthy of further investigation.

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.
