(Instituto de Tecnologia e Educação Galileo da Amazônia, 2021) NASCIMENTO, Mauro Reis ALENCAR, David Barbosa de NASCIMENTO, Manoel Henrique Reis MONTEIRO, Carlos Alberto; LEITE, Jandecy Cabral
The industrial production of preforms for PET bottles requires strict control of the PET resin drying temperature to minimize the generation of acetaldehyde (ACH), a compound that can alter the taste of beverages. This study proposes the use of Artificial Neural Networks (ANN) of the Backpropagation type (Cascadeforwardnet) to support decision-making in controlling the ideal drying temperature. The methodology included data collection from the preform injection process and the application of Computational Intelligence techniques to predict ACH levels. The results demonstrate that ANN can optimize the management of production parameters, reducing waste and improving the quality of the final product.

(Instituto de Tecnologia e Educação Galileo da Amazônia, 2021) PAIVA, Ana Paula Cardoso Queiroz de LIMA, Alexandra Amaro de SILVA, Daniel Nascimento e; LEITE, Jandecy Cabral
Environmental issues remain a growing agenda worldwide, with a significant focus on the Amazon. However, the human contingent inhabiting this region, particularly family farmers, is often overlooked. The Rural Environmental Registry (CAR) was created as a tool to promote sustainable public policies and enable environmental and land regularization for these communities. This literature review study investigates CAR's contribution to family farmers in the state of Amazonas from a legal and environmental perspective. The results indicate that understanding the legal aspects and registration process of CAR is essential for compliance. The simplified registration process for family farmers facilitates legal compliance, promoting environmental and land tenure regularization and reducing territorial conflicts. The study concludes that implementing the Brazilian Forest Code, with technical support, is crucial for the sustainability of family farming in the Amazon.
Evaluation of Radiated Electromagnetic Immunity of the IoT LoRa Protocol
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2021) RIBEIRO, Jhonatan; SANTOS, Eliton Smith dos; ALENCAR, David Barbosa de; NASCIMENTO, Manoel Henrique Reis do; SANTOS, Alyson de Jesus dos; LEITE, Jandecy Cabral
With the advancement of Industry 4.0, industrial automation has transitioned to wireless networks, enhancing flexibility and efficiency. Technologies such as LoRaWAN are widely adopted due to their low power consumption and long-range communication capabilities. However, the increasing density of connected devices presents challenges related to electromagnetic interference (EMI), which can degrade network performance. This study evaluates the radiated electromagnetic immunity of the LoRa protocol, testing Heltec LoRa ESP32 V2 boards according to IEC 61000-4-3 standards. The tests, conducted in an anechoic chamber at frequencies from 80 MHz to 6 GHz with a field intensity of 10 V/m, revealed sensitivity to EMI at specific frequencies (305 MHz and 730 MHz), leading to packet loss and communication failures. These findings highlight the need for enhanced filtering, shielding, and protocol adjustments to improve the robustness of industrial LoRa-based communications.
Computational meta-heuristics based on Machine Learning to optimize fuel consumption of vessels using diesel engines
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2021) SIQUEIRA JÚNIOR, Paulo Oliveira; NASCIMENTO, Manoel Henrique Reis; SILVA, Ítalo Rodrigo Soares; PARENTE, Ricardo Silva; FONSECA JÚNIOR, Milton; LEITE, Jandecy Cabral.; LEITE, Jandecy Cabral
With the expansion of river transportation, especially in the case of small and medium-sized vessels that make longer routes, the cost of fuel, if not taken as an analysis criterion for a larger profit margin, is considered a primary factor, considering that the value of fuel, specifically diesel, to power internal combustion engines is high. Therefore, the use of tools that assist in decision-making becomes necessary, as is the case of the present research, which aims to contribute with a computational model of prediction and optimization of the best speed to decrease fuel cost, considering the characteristics of the SCANIA 315 propulsion model, of a vessel from the river port of Manaus that carries out river transportation to several municipalities in Amazonas. According to the results of the simulations, the best training algorithm of the Artificial Neural Network (ANN) was the BFGS Quasi-Newton, considering the characteristics of the engine for optimization with Genetic Algorithm (GA).
Composting Model with The Reuse of Organic Waste in Rural Schools
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2021) SIMÕES, Natália Cristina Bezerra de Alencar; ALENCAR, David Barbosa de; BEZERRA, Alberto de Souza; NASCIMENTO, Manoel Henrique Reis; FERRO, Any Karoline Bezerra de Alencar; PINTO JÚNIOR, José Roberto Lira.; LEITE, Jandecy Cabral
School institutions become producers of organic waste as a result of the daily consumption of school meals offered to students during the school year. An alternative to prevent this material from being incorrectly released into the environment is the implementation of a composting model that reuses organic waste, generating humus, which will serve as fertilizer for the implementation of a vegetable garden in rural schools. This work aims to propose a composting model in a rural school in Manaus for the reuse of organic waste, develop a composter prototype for the production of humic substances and mineral nutrients for garden creation, prepare a manual with guidelines for the correct and sustainable management of the composting plant and the school garden, and implement the garden system through the composting process using school organic waste. The work is a case study that seeks to raise awareness among the school community for the proper management and reuse of solid waste generated by the school, as well as to arouse interest in environmental education and behavior change for environmental preservation among students and teachers.
