Non-grain oriented electrical steel photomicrograph classification using transf...
Ivo, Roberto Fernandes; Rodrigues, Douglas de Araújo; Bezerra, Gabriel Maia; Freitas, Francisco Nélio Costa; Abreu, Hamilton Ferreira Gomes deAmong the many factors that contribute to achieving a sustainable and efficient economy is the raw material of machinery and equipment of strategic sectors. Non-grain oriented (NGO) electrical steel is used in the manufacturing of electric motors. Therefore, it is directly related to the electromagnetic efficiency of engines both in industry and in homes. This work aims to develop an intelligent 1.26% Si NGO el...
New approach to evaluate a non-grain oriented electrical steel electromagnetic ...
Rebouças Filho, Pedro Pedrosa; Santos, José Ciro dos; Freitas, Francisco Nélio Costa; Rodrigues, Douglas de Araújo; Ivo, Roberto FernandesThe growing global demand for energy makes it necessary to adopt measures ranging from the exploration of new energy sources to the development of technology for machinery and equipment with greater energy efficiency. Non-grain oriented electrical steels are widely used in the construction of rotors and stators that form the core of electric motors, and their microstructures are directly related to its electrom...
Study and classification of the Crystallographic Orientation Distribution Funct...
Ivo, Roberto Fernandes; Rodrigues, Douglas de Araújo; Santos, José Ciro dos; Freitas, Francisco Nélio Costa; Herculano, Luís Flávio GasparThis article discusses a fast and efficient classification of non-grain oriented electrical steel and its electromagnetic efficiency based on the analysis of the images of the Crystalline Orientation Distribution Function (CODF). The study was carried out on samples of a non-grain oriented electrical steel, semi-processed with 1.28% silicon, cold rolled with thickness reductions of 50.0% and 70.0%, and annealed...
Redes Volumétricas Totalmente Convolucionais em Cascata para Segmentação 3D de ...
Ivo, Roberto FernandesThe absence of cardiac chambers, holes in the heart and abnormal connections cause the death of hundreds of people every year. The clinical team involved in the diagnosis and treatment decisions for congenital heart disease (CHD) must be consistent in their choices. Therefore, in cases of CHD there is a need for a system that is capable of segmenting the whole heart and large blood vessels in 3D efficiently, qu...
