Aluminum-hydrogen peroxide power system for an unmanned underwater vehicle
Bibliographic record
Abstract
Alupower Canada Limited and the Department of National Defence with CRAD funding and DGMEM engineering support are designing and constructing a fuel cell power system (FCPS) to power small unmanned vehicles (UUVs). The ARCS 1, a DND/DREP owned experimental unmanned submersible, has been chosen as the trial vessel. The FCPS will provide sufficient energy to allow the UUV to operate submerged, continuously for 30 hours which is approximately 4 to 6 times the endurance of its existing nickel cadmium system. Unmanned underwater vehicles are attaining increasing importance as "force extenders" for more conventional manned maritime vehicles in times of budgetary constraint. Despite rapid advances in many UUV systems such as navigation and sensor technology, UUVs are now limited by the availability of an advanced power source capable of attaining the desired mission. A steady state power output of 1.7 kW is achieved within a volume of 375 litres and system mass of 315 kg.>

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
