Abstract

fetched live from OpenAlex

Cet article présente une nouvelle méthode de résolution du problème de contact mécanique frottant, celle du lagrangien augmenté adapté. Contrairement aux méthodes les plus utilisées (pénalisation et lagrangien augmenté), l’utilisateur ne doit pas déterminer les valeurs des coefficients de pénalisation. Cette méthode est performante aussi bien avec des matériaux élastiques qu’élasto-plastiques. Le problème de Hertz est présenté. Cette méthode est au si utilisée dans le contexte multi-physique.

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.
