IRIS: Extração, Organização e Classificação de Conteúdos do Projeto Pedagógico de Curso do Técnico em Automação Industrial

ABSTRACTTraditional search systems on the World Wide Web haverevolutionized searching for information, almost wholly replacingphysical encyclopedias. However, these systems must developnew search methods that make the process more efficient andcomprehensive for students. In technical courses, it is common forstudents to struggle with searching for quality content on theinternet that serves both as a bibliographic base for the disciplinesand as reference material to deepen their knowledge. TheIntelligent Research Interactive System (IRIS) automates searchesfor contents of the fields in the Industrial Automation TechnicalCourse to contribute to an effective improvement in the quality oftheir studies and reduce the time spent in processes that are notlinked to the education activities

Analysis of the models used to forecast microstructural parameters obtained during the directional solidification of austenitic stainless steel AISI 304

In the case of dendritic structure, the mechanical properties of foundry products depend on the parameters: primary and secondary arm spacings. Therefore, it is very important that the computational programs use reliable equations for correlating the calculated thermal parameters with the obtained interdendritic spacings. This study presents a numerical and experimental analysis of some models for predicting the secondary arm spacings as a function of thermal parameters. The comparison between the numeric and experimental results for stainless steel permits the determination of the adequate equation for unidirectional solidification.60113514
