Item Propriedades Elétricas das Buchas de Isolamento das Subestações de Alta Tensão: Um Estudo das Novas Tecnologias - Materiais(INSTITUTO DE TECNOLOGIA, 2013) DUARTE NETO, Luiz Pinheiro; CIRINO, Weverson dos Santos; HOLANDA, Ubiratan Bezerra.; Prof. Dr. Carlos Tavares da Costa JúniorThe use of electrical bushings is very important in the design of a substation and is a key part of high voltage equipment. The article provides a detailed study of the main properties of high voltage bushings and their characteristics, as well as new technologies being developed for the design of more reliable and less fault-prone electrical bushings.Item Optimización del proceso de montaje de componentes SMD usando algoritmo genético multiobjetivo en la industria(INSTITUTO DE TECNOLOGIA, 2014) CIRINO, Weverson dos Santos; MUSTAFE, Nadime; REIS, Ana; CASTRO, Anderson; BEZERRA, Ubiratan Holanda; Professora Dra. Fernanda Souza do NascimentoThe article proposes the optimization of the assembly sequence of SMD components on printed circuit boards using a multi-objective genetic algorithm (NSGA-II). The study was conducted in an electronics industry at the Manaus Industrial Hub, showing that the proposed algorithm outperformed the traditional machine inserter optimizer, reducing assembly time by 6 seconds per board and increasing productivity by 30%. The results highlight the effectiveness of NSGA-II in solving complex industrial optimization problems.Item Sistema de Controle de Temperatura Digital como Ferramenta para a Eficiência Energética na Indústria(INSTITUTO DE TECNOLOGIA, 2014) CIRINO, Weverson dos Santos; MUSTAFE, Nadime; REIS, Ana; CASTRO, Anderson; TANAKA, Gerdson; TOSTES, Maria Emília; BEZERRA, Ubiratan Holanda; TOSTES, Maria Emília; BEZERRA, Ubiratan HolandaThe study presents the implementation of a digital temperature control system based on hysteresis to optimize energy efficiency in a plastic injection industry. The results demonstrate a significant reduction in energy consumption, with annual savings of approximately R$ 47,166.86, along with improvements in temperature stability, reduced maintenance costs, and extended equipment lifespan. The system proved economically viable, with a return on investment in 39 days.
