Abstract
This paper summarizes the ballistic considerations of a general project concerning the protection against the threats associated with improvised explosive devices (IEDs). IEDs generate two kinds of threats: blast and fragments. One possible protection combines a ballistic textile (Kevlar®) to stop the fragments and a crushable material (Crushmat®) for absorbing the blast. In order to properly develop an optimized protection, the different materials were tested separately before combining them. Numerical models were also developed with DYNAFAB® and LS-DYNA® in order to determine and optimizethe relevant design parameters. Good correlations were obtained between the models and the experiments. The investigated combined protection system could serve as an interesting basis against more general terrorist threats like fragmentation bombs. The evolution of computer resources will allow modeling such complex assemblies of materials with more details and reduce the calculation time. doi:10.12783/issn. 2168-4286/2.2/Gilson

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
