Abstract

fetched live from OpenAlex

PDF | Este trabalho apresenta o desenvolvimento e aplicação prática de uma metodologia para seleção de tecnologia de fabricação de gusa para condições locais específicas. A metodologia é baseada num processo conduzido em dois estágios de análise técnica e econômica com intuito de filtrar e eliminar as tecnologias desfavoráveis sob certas condições. O primeiro estágio inclui uma avaliação de todos os dados disponíveis aplicados a uma tecnologia específica com a seleção de até três das melhores tecnologias baseadas em análise de risco, período de retorno simples (“pay-back”), análise de investimento de capital e de custos de operação. O segundo estágio inclui uma avaliação econoômica-financeira mais detalhada para selecionar a melhor /mais viável tecnologia . A aplicação desta metodologia vem facilitando a recomendação e/ou rejeição, por parte da HATCH, de tecnologias de fabricação de gusa disponíveis para várias siderúrgicas com o objetivo de atendimento de necessidades específicas.

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.
