1. The Effectiveness of Back Pressure in Superplastic Blow Forming of Aluminum Alloy AA 5083 Performed at Very Favorable Conditions for Cavitation Growth
Many components for aerospace and automotive industries are currently manufactured using superplastic forming, being the fine-grained aluminum alloy AA5083 widely used for this proposes. However, the development of cavitation voids is inherent in this process and reduces the ductility of the alloy. Back pressure can be used to diminish the growth of cavitati

2. A Doubly Curved Axisymmetric Finite Element for Subsea Sandwich Domes
Abstract The paper focuses on the analysis of sandwich domes using a newly developed doubly curved axisymmetric sandwich finite element. The simple equivalent single layer finite element employs a cubic polynomial approximation for transverse displacement and meridional displacement. The present element accounts for the transverse shear strains of the facing

10. Data clustering by optimum-path transform / Agrupamento de dados por florestas de caminhos otimos
This thesis proposes a novel approach for data clustering based on optimum-path forest. The samples are taken as nodes of a graph, whose arcs are defined by an adjacency relation. The nodes are weighted by their probability density values (pdf) and a connectivity function is maximized, such that each maximum of the pdf becomes root of an optimum-path tree (c
