Abstract

fetched live from OpenAlex

Tendo-se em vista a importância sócio-econômica que as barragens possuem no Brasil e os grandes investimentos realizados acerca destas estruturas,o objetivo deste trabalho é contribuir para o estudo destas estruturas, através do desenvolvimento de um programa em linguagem Matlab para a análise de tensões em barragens gravidade de concreto. As rotinas desenvolvidas permitem verificações comuns em projetos de barragens, dentre as quais se destaca a possibilidade de se considerar a ação de sedimentos e sismos, além da possibilidade de variar, em uma mesma análise, parâmetros geométricos e propriedades físicas dos materiais do perfil estudado. A análise dos sismos é abordada segundo doi métodos quais sejam: método Pseudo-Estático (Método de Westergaard) e Pseudo-Dinâmico (Método de Chopra). Antes da apresentação das subrotinas desenvolvidas, os principais métodos de análise de tensões, ocasionadas pelas ações sísmicas, são brevemente discutidos e, após, são feitas diversas validações de resultados com o auxílio do programa CADAM 2000, desenvolvido pela Escola Politécnicas de Montreal. Apresentam-se ainda análises adicionais referentes às potencialidades do programa, assim como as principais conclusões.

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.

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.
