Abstract

fetched live from OpenAlex

O conhecimento do comportamento termodinâmico de misturas é uma informação relevante durante o projeto de equipamentos empregados em processos de separação. Tradicionalmente para a representação do equilíbrio de fases de misturas envolvidas nestes processos são empregados modelos de coeficiente de atividade. Esses por sua vez possuem parâmetros de interação intermoleculares que precisam ser determinados a partir de dados experimentais de equilíbrio. A determinação destes parâmetros caracteriza um problema inverso, isto é, um problema de estimação de parâmetros. Neste cenário, o presente trabalho tem por objetivo a determinação dos parâmetros de interação do sistema ternário acetato de etila/água/açúcar usando o Algoritmo de Evolução Diferencial com sub- populações. Para essa finalidade utilizou-se dados experimentais de equilíbrio para sistemas ternários e modelos tradicionais de coeficiente de atividade em temperaturas distintas. Foram estimados parâmetros dos modelos de Wilson, NRTL e UNIQUAC. Os resultados obtidos indicam que metodologia proposta configura-se como uma interessante alternativa para a resolução do problema inverso proposto.

Not 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.
