Item Barrido de Frecuencia en Coordenadas de Fase para Sistemas Desequilibrados(INSTITUTO DE TECNOLOGIA, 2012) CABRAL LEITE, Jandeey; TOSTES, Maria Emilia de Lima; PÉREZ ABRIL, Ignacio; MEDEIROS, Adelson Bezerra de; AZEVEDO, Manoel Socorro Santos; BEZERRA, Ubiratan Holanda; MAGALHÃES, Edilson MarquesThe paper develops a phase-coordinates model for analyzing unbalanced electrical networks, enabling the specification of single-phase or three-phase harmonic injections of any sequence. The model is applied to a four-wire delta system, demonstrating its ability to represent structural asymmetries and identify resonances at different frequencies.Item Methodology Proposal for Multicriteria Optimization Using NSGA-II in Industrial Applications(INSTITUTO DE TECNOLOGIA, 2023) CASTRO, Anderson de Oliveira; BEZERRA, Ubiratan Holanda; LEITE, Jandecy Cabral; AZEVEDO, Manoel Socorro Santos.; Professor Dr. Bernardo Borges Pompeu NetoThe paper proposes a methodology for multicriteria optimization using the NSGA-II genetic algorithm in industrial applications, specifically in the assembly process of electronic components in surface mount technology (SMT) machines. The study addresses problems such as feeder arrangement and head routing, aiming to reduce the total cycle time. The methodology integrates known approaches and applies multi-objective optimization to enhance machine performance, with results validated in a real industrial environment.Item Processamento Primário da Informação Gerada por Registradores de Perturbações(INSTITUTO DE TECNOLOGIA, 2014) AZEVEDO, Manoel Socorro Santos; HORTA, Roberto Luis Ballesteros; LEITE, Jandecy Cabral; BEZERRA, Ubiratan Holanda; TOSTES, Maria Emília de Lima; MAGALHÃES, Edilson MarquesThe study focuses on the primary processing of data generated by Digital Fault Recorders (DFRs) in electrical systems, aiming to streamline the analysis of oscillographic records for operators and specialists. Using LabVIEW and the COMTRADE standard, a modular software was developed for data acquisition, processing, storage, and interactive visualization. The system enables quick disturbance searches and lays the groundwork for implementing computational intelligence (CI) techniques to aid decision-making.Item Despacho Econômico e Ambiental de Energia Elétrica Usando Técnicas Computacionais em LabVIEW: Uma Abordagem Multiobjetivo para Sistemas de Geração Termelétrica(INSTITUTO DE TECNOLOGIA, 2013) AZEVEDO, Raimundo Edney dos Santos; BEZERRA, Ubiratan Holanda; LEITE, Jandecy Cabral; AZEVEDO, Manoel Socorro Santos; NETO, Vilmar Domingos da Silva; MAGALHÃES, Edilson MarquesThis paper proposes an analytical strategy based on mathematical models to address the load dispatch problem in thermal power plants, simultaneously considering economic and environmental criteria. Using the computational tool LabVIEW, the study develops a multi-objective model that minimizes operational costs and pollutant emissions (SO₂ and NOₓ) while meeting energy demand. The results demonstrate the approach's effectiveness across different load scenarios, highlighting solutions that balance energy efficiency and environmental impact reduction.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.Item Um Algoritmo Evolutivo para Aplicação na Compensação da Potência Reativa em Redes de Distribuição de Energia Elétrica(INSTITUTO DE TECNOLOGIA, 2017) AZEVEDO, Alysson Roberto; AZEVEDO, Manoel S. Santos; LEITE, Jandecy Cabral; BEZERRA, Ubiratan Holanda; ABRIL, Ignacio Pérez; Prof. Dr. Carlos Tavares da Costa JúniorThis article proposes the use of genetic algorithms for the multi-objective optimization of reactive power compensation in electric power distribution networks. The method aims to locate and size compensation units, such as capacitor banks and passive filters, to maximize economic benefits and maintain power quality indices according to Brazilian standards. The study includes the analysis of a real case in the Manaus Industrial Pole (PIM), demonstrating the approach's effectiveness in scenarios with low and high harmonic penetration.
