Abstract

fetched live from OpenAlex

Abstract Explosives and propellants are chemical compounds that undergo chemical decomposition reactions at very fast speeds, producing gaseous products, and a great deal of heat. In some circumstances a blast wave can be produced. The information provided here gives an introduction to this process covering the theory of detonation and deflagration. Explosives can be divided into three classes, ( 1 ) primary explosives, ( 2 ) secondary explosives, and ( 3 ) propellants. The behavior and performance of these three classes of explosives is discussed. Physical and chemical data on primary and secondary explosives is given together with details of new high temperature explosives. Lastly future developments in explosives technology are presented with regards to enhancing the performance, insensitive munitions and demilitarization.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
