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 Caracterização do Solo do Município de Santarém com Base no SPT(INSTITUTO DE TECNOLOGIA, 2015) AGUIAR, Jaciclei Antonio Carneiro de; OLIVEIRA, Dênio Ramam Carvalho de; POMPEU NETO, Bernardo Borges; MAGALHÃES, Edilson MarquesThe study aims to characterize the soil of Santarém municipality using the Standard Penetration Test (SPT), dividing the area into 8 zones for geotechnical analysis. Soil type, profile, geotechnical characteristics, and penetration resistance (Nspt) were evaluated, highlighting significant variations in nearby areas and the influence of the water table.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 Comparativo da Produção de Concreto na Amazônia – Cidade de Santarém(INSTITUTO DE TECNOLOGIA, 2014) SANTOS, Ivens Silva dos; POMPEU NETO, Bernardo Borges; OLIVEIRA, Dênio Ramam Carvalho de; MACÊDO, Alcebíades Negrão; MAGALHÃES, Edilson MarquesThe study compared the production of concrete in batching plants and on-site in Santarém-PA, identifying the most used methods and the factors affecting material quality. Technical visits and interviews with professionals highlighted the prevalence of mixer use, lack of technological control, and poor aggregate quality as main challenges.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 Medición eléctrica del nivel de los depósitos de combustible en plantas termoeléctricas para el gerenciamiento de la logística de suministro(INSTITUTO DE TECNOLOGIA, 2020) SILVA NETO, Almiro Gomes da; LEITE, Jandecy Cabral; MACIEL, Paulo Henrique de Lima; Professora Dra. Fernanda Souza do NascimentoThis article presents a proposal for an electric measurement system for fuel tanks in thermoelectric plants, replacing the traditional manual method that shows inaccuracies. The proposed technology aims to enhance the logistics of fuel supply—critical for thermoelectric plant operation—through an automated system using capacitive probes, offering greater precision, reliability, and continuous monitoring of fuel levels.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 Melhor aproveitamento da energia elétrica na indústria(INSTITUTO DE TECNOLOGIA, 2014) SOARES, Gerdson Tanaka; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota; Profª. Drª Aline Maria Meiguins de LimaThis paper presents a proposal for an industrial energy management system focused on low-cost actions, based on measurement, recording, control, and automation. Through a case study in a plastics industry located in the Industrial Pole of Manaus, it was possible to demonstrate energy savings of up to 35.5%, using the Measurement and Verification (M&V) methodology. The study highlights the importance of integrated management as a tool for energy efficiency, with positive impacts on productivity, cost, and sustainability.
