Item PROJETO MULTICRITÉRIO DE FILTROS HARMÔNICOS PASSIVOS PARA INSTALAÇÕES INDUSTRIAIS UTILIZANDO TÉCNICAS DE INTELIGÊNCIA COMPUTACIONAL(Universidade Federal do Pará, 2013) LEITE, Jandecy Cabral; TOSTES, Maria Emília de LimaDue to the industrial growth in Northern Brazil, especially at the Manaus Industrial Pole (PIM), mathematical tools are needed to assist experts in selecting and sizing harmonic filters that neutralize the harmful effects of harmonics generated by nonlinear loads and ensure compliance with power quality standards. Additionally, passive harmonic filters (PHF) can act as reactive power compensators, achieving significant energy billing savings. This thesis develops a mathematical method and a computational tool for selecting the configuration and design parameters of PHFs in industrial systems, formulating the problem as a multi-objective optimization that considers both harmonic distortion reduction and the project's economic effectiveness, complying with Brazilian and international standards. The computational solution is based on the NSGA-II genetic algorithm, generating a Pareto front of optimal solutions that allow designers to select the most suitable option. The tool includes innovative features, such as automatic selection of filter configuration and number of branches, and considers various operational scenarios. Validation was performed through practical examples that demonstrated the advantages of the proposed method.Item Comparação do Impacto Ambiental duma Usina Elétrica quando Utiliza Motores de Óleo Combustível Pesado e quando Utiliza Motores a Gás(INSTITUTO DE TECNOLOGIA, 2013) SILVA, Wagner Ferreira; CAMPOS, Lucila Maria de Souza; MIGUEL, Paulo Augusto Cauchick; RODRIGUEZ, Jorge Laureano Moya; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesThe study compares the environmental impact of a power plant in the Brazilian Amazon when using heavy fuel oil (HFO) engines and natural gas engines. It analyzes emissions of pollutants such as CO, CO₂, NOx, SOx, and particulate matter, noting that gas engines emit less NOx and SOx but more CO and CO₂ per unit of power supplied.Item Logística Reversa de Pós-Consumo de Bateria de Celular(INSTITUTO DE TECNOLOGIA, 2012) SILVA, Carlos Américo de Souza; LEITE, Jandecy Cabral; VIEIRA, Kellen Bicho; MAGALHÃES, Edilson MarquesThis study examines reverse logistics as a tool for sustainable development, focusing on the proper disposal of mobile phone batteries, which contain heavy metals harmful to the environment. The research analyzed manufacturers, mobile operators, and consumers in the Manaus Industrial Pole (PIM), identifying challenges such as low consumer participation in the return process, despite the availability of return channels. The results emphasize the need for awareness campaigns and better-structured reverse channels to reduce improper disposal and promote recycling.Item Materiais compósitos de matriz poliéster reforçados com resíduos de madeira de diferentes morfologias(INSTITUTO DE TECNOLOGIA, 2013) LOPES, Carlos Eduardo Pinto; PEREIRA, Léo César de Oliveira; COSTA, Deibson Silva da; LOPES, Raimundo Valdan Pereira; PINTO, Vagner Barroso; LEITE, Jandecy Cabral; FUJIYAMA, Roberto Tetsuo; MAGALHÃES, Edilson MarquesThis study presents the production and characterization of polyester matrix composites reinforced with residues from the Amazon timber industry. Using Angelim Pedra wood powder in different particle sizes and weight fractions (6.86% and 10.86%), the composites were evaluated for their mechanical properties through tensile tests. The results showed that smaller particles increase tensile strength, indicating that the reuse of these residues is viable and contributes to industrial sustainability.Item Material Compósito de Matriz Polimérica Reforçada com Fibras Vegetais de Curauá e Sisal(INSTITUTO DE TECNOLOGIA, 2013) SANTOS, Eduardo de Jesus Silva dos; TAKAHASHI, Rafael; COSTA, Deibson Silva da; LOPES, Raimundo Valdan Pereira; PINTO, Vagner Barroso; LEITE, Jandecy Cabral; FUJIYAMA, Roberto Tetsuo; MAGALHÃES, Edilson MarquesThis study evaluated the manufacturing process of polymer matrix composites reinforced with natural curauá and sisal fibers, focusing on a fiber length of 25 mm. The methodology involved producing prepregs by spraying polyester resin diluted in styrene and manual lamination followed by compression molding. Specimens were tested according to ASTM D3039, showing that the curauá fiber composite exhibited higher tensile strength (average of 680.72 N) compared to sisal (431.53 N). The results confirmed the feasibility of the process and the influence of fiber type and length on the mechanical properties of the material.Item Mejoramiento de los índices de eficiencia energética en sistemas de climatización en el territorio de Manaus(INSTITUTO DE TECNOLOGIA, 2012) DA SILVA, Jorge Lucio; LEITE, Jandecy Cabral; DE LEÓN BENITEZ, Carlos Alberto; BERALDO HERRANDÉZ, Francisco; MAGALHÃES, Edilson MarquesThe climate control systems are among the most significant energy loads in industrial, residential, and service facilities. This research is based on a diagnostic study carried out in the Industrial Pole of Manaus, employing Brazilian national standards as reference models. As an improvement strategy, the adoption of high-efficiency air conditioning systems is proposed to reduce energy consumption.Item Metodologia de diagnóstico de manutenção baseada em condição de enrolamentos estatóricos em hidrogeradores(INSTITUTO DE TECNOLOGIA, 2010) SANTOS, Renato Lelio da Silva; OLIVEIRA, Roberto Célio Limão de; LEITE, Jandecy Cabral; Edilson Marques MagalhãesThis paper presents a methodology applied at the Balbina Hydroelectric Power Plant to diagnose faults in stator windings of hydro generators, using partial discharge monitoring as a predictive maintenance tool. This technique enables the identification of insulation deterioration and supports decision-making based on reliable data, reducing costs, increasing reliability, and avoiding unnecessary maintenance. The methodology allows for more effective maintenance planning, extending equipment lifespan.Item Metodologia de um programa de sugestão de melhoria(INSTITUTO DE TECNOLOGIA, 2011) BRITO, Orleans Marques de; SILVA, Carlos Americo de Souza; LEITE, Jandecy Cabral; Eduardo de Magalhães BragaThe article presents a methodology for a continuous improvement suggestion program, analyzing its implementation in an industry at the Manaus Industrial Hub. The program encourages employees to propose ideas for solving problems and innovating processes and products, generating benefits such as cost reduction and increased competitiveness. Results from the first year show 447 suggestions submitted, with 266 implemented, resulting in savings of BRL 98,253.00.Item Estudio de la influencia del ciclo de arranques y paradas en el estator de generadores síncronicos(INSTITUTO DE TECNOLOGIA, 2013) SANTOS, Renato Lélio da Silva; OLIVEIRA, Roberto Célio Limão de; LEITE, Jandecy Cabral; AZEVEDO, Manoel Socorro Santos; ESTEVES, Anderson Fernandes; MACIEL, Paulo Henrique de Lima; MAGALHÃES, Edilson MarquesSynchronous generators undergo frequent start-stop cycles due to maintenance or external factors, causing thermal variations that affect stator insulation. This study, conducted at the Balbina hydroelectric plant in Amazonas, Brazil, examines insulation aging trends in stators through partial discharge testing. Results indicate that continuous operation increases the generators’ lifespan.Item Estudo Comparativo dos Processos Produtivos entre Linhas em Série e Células(INSTITUTO DE TECNOLOGIA, 2010) SOARES, José Josimar; LEITE, Jandecy Cabral; FARIA, Marlene Araujo de; Profa.
