This case study, carried out at a construction site in Manaus, analyzes solid waste management practices in construction and proposes strategies to promote sustainable development. The research highlights the application of CONAMA Resolution No. 307/2002 for the classification and management of construction and demolition waste (RCD) and the search for integrated solutions such as recycling and reuse directly on site.Item Aplicação integrada de Lean Office e Indústria 4.0 para otimização de processos administrativos de emissão de notas fiscais(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SOARES, Vera Alana Nobre; ALENCAR, David Barbosa deThe dissertation addresses the combined application of Lean Office, Industry 4.0 and fuzzy logic in optimizing administrative processes related to issuing invoices. With the use of tools such as Value Stream Mapping (VSM), Kaizen, 5S, robotic process automation (RPA), IoT, Big Data and artificial intelligence, the study proposes an integrated solution to reduce costs, improve solutions and increase productivity. efficiency of administrative operations. Carried out in a company in the electrical materials sector, the results showed improvements in agility, operational costs and customer satisfaction.Item Aplicação da teoria dos jogos na análise de riscos e decisões no mercado de ações(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) BOTTI, Matheus Costa Moreira; ALENCAR, David Barbosa deThe stock market is characterized by its high volatility and the complexity of interactions among investors, where strategic decisions significantly impact both individual behavior and overall market dynamics. This dissertation investigates the application of game theory to risk analysis and decision-making in the stock market, integrating technical and financial indicators into a model that predicts and optimizes investment strategies. The study identified Nash equilibria in various market scenarios, advancing the use of game theory in strategic analyses and professional practices in the financial sector.Item Análise das propriedades mecânicas do concreto com adição de seixo e polietileno tereftalato (PET)(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) BEZERRA, Antonio Carlos Lapa; ALENCAR, David Barbosa deThe increasing production of plastic waste, particularly Polyethylene Terephthalate (PET), poses a significant environmental challenge due to its long degradation time and negative environmental impact. This study investigates the feasibility of using ground PET as a partial replacement for fine aggregate (sand) in concrete production. Mixtures with 0%, 10%, 30%, and 50% sand replacement by PET were prepared. Tests at 28 days of curing showed that PET addition in certain proportions maintained the required strength and provided environmental benefits, such as reducing natural sand extraction and reusing plastic waste, reinforcing the technical and environmental viability of using recycled PET in concretes.Item Uso dos conceitos do Lean para a melhoria de serviços educacionais: O caso das escolas públicas do estado do Amazonas(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024-11) COSTA, Lucas Lima da; VIEIRA JUNIOR, MiltonThis study proposes the application of Lean principles and tools to improve educational services in public schools in Amazonas. Focusing on eliminating waste and optimizing processes, it analyzes how Lean can improve quality, reduce costs and promote stakeholder satisfaction. Using case studies, the article highlights results such as reducing waste, increasing efficiency and organization, and challenges related to implementation in educational contexts, emphasizing the importance of adaptive and collaborative approaches.Item Sistema de irrigação automatizado orientado pela compensação da evapotranspiração da cultura(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SILVA, Edivaldo Amarante da; NASCIMENTO, Manoel Henrique ReisThe imbalance between population growth and agricultural production increases the demand for food, making irrigation efficiency essential for food security. This study develops an automated irrigation system based on the Penman-Monteith method to calculate evapotranspiration and irrigation pulse. An experiment compared methods based on evapotranspiration and accumulated radiation, showing the former was 7% more water-efficient. The system uses an ESP32 microcontroller, radiation, humidity, and temperature sensors, promoting water savings and better agricultural management.Item Sistema de inferência fuzzy para avaliação da conformidade do ensaio de mostradores de energia, baseado em normas(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SOUZA, Márcio André de Oliveira; BRITO JUNIOR, Jorge de AlmeidaThis dissertation develops a fuzzy inference system to evaluate the compliance of energy meter displays according to the criteria of Portaria 221, May 23, 2022. Using fuzzy logic, the system analyzes variables such as Digit Segment Quality (QSD), sharpness, and functionality, providing a more precise and adaptable evaluation. The model proposes improvements in cost, speed, and scalability by automating the analysis and reducing human errors, standing out as an effective tool for quality control in industrial environments.Item Sistema de inferência fuzzy para análise dos requisitos técnicos dos taxímetros(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024-11) LEITE, Yago Ruan Binda; NASCIMENTO, Manoel Henrique ReisThis research implements a fuzzy inference model to support the preliminary technical analysis of taximeters, aiming for greater accuracy and reliability in inspections according to Ordinance No. 124, March 24, 2022. The methodology was structured in three phases: identification of technical indicators, fuzzy system modeling, and model experimentation. Using Matlab R2013a - Fuzzy Toolbox, variables, fuzzy sets, and inference rules were defined. Results indicated that the model replicates real inspection conditions, reducing subjectivity and promoting uniformity in evaluations.Item Estimativa da incerteza de medição nos ensaios de resistência elétrica de fios e cabos elétricos para tensões nominais de até 450/750V(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) CAVALCANTE, Henrique Augusto Mota; ALENCAR, David Barbosa deThe national market for electrical wires and cables faces products of dubious quality, with electrical resistance exceeding normative limits, which may cause fires. This dissertation addresses the importance of ensuring the compliance of these products, focusing on the estimation of measurement uncertainty in electrical resistance tests for wires and cables with nominal voltages up to 450/750V. The "top-down" methodology was applied, using the Ishikawa Diagram, enabling the creation of a mathematical model to calculate combined standard uncertainty. Tests conducted on samples from factories and the market revealed non-conformities, emphasizing the need for improved inspection and measurement processes.
