Item Sistema de Visão AI-Powered para Correção de um Dispensador de Adesivos Axxon para SMT em uma Indústria do Pólo Industrial de Manaus - PIM(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) BRITO, Hallisom Luniere; BRITO, Ynara Silva Luniere; MAUES, Elvis Jardim; VIEIRA JUNIOR, MiltonThis paper presents the development and application of an intelligent system based on computer vision and artificial intelligence for monitoring and automatic correction of the adhesive application process on printed circuit boards (PCB) in the electronics industry. The adhesive application process is essential for the precise fixing of components, and eventual failures can compromise the quality and performance of the final products. To automate visual inspection and reduce the occurrence of human errors, a convolutional neural network (CNN) model trained with real images of the production line was developed, capable of identifying correct patterns and failures in the application of the adhesive. The system integrates highresolution cameras, image processing software and a control interface, enabling real-time monitoring and the execution of automatic corrective actions. The results obtained demonstrate the effectiveness of the proposed system, with a high level of accuracy in detecting faults, contributing to improving the quality of the production process and aligning with the principles of Industry 4.0. The research concludes that the adoption of intelligent systems based on computer vision represents a significant advance for quality control in the manufacturing of electronic devices.Item Análise de Viabilidade Econômico-financeira e de Maturidade para Implementação de Conceitos Indústria 4.0(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) TAHE, Thyago Mileo; CAD, Sandra Viana; NASCIMENTO, Manoel Henrique ReisThe adoption of Industry 4.0 technologies and concepts has proven to be an effective strategy for increasing the competitiveness of industrial corporations. However, many industries still face difficulties in assessing, in a simple yet structured manner, both the economic and financial viability and their level of maturity for adopting these technologies. This research aimed to develop a simplified model capable of analyzing, in an integrated manner, the financial viability and the level of organizational maturity for Industry 4.0 technologies implementation of industries in the electronics sector. The proposed model combines Return on Investment (ROI), a traditional tool for analyzing economic and financial viability, with TOE (Technology, Organization and Environment), a method for assessing maturity for adopting new technologies. The study carried out a case study of an electronics industry in the Industrial District of Manaus. This industry has already begun its technological transition to Industry 4.0 but has not previously applied any feasibility analysis method. The results of this case study indicate that the investment has a highly positive return, and that the organization is at an appropriate level to continue implementing Industry 4.0 technologies.Item Development of an Intelligent Monitoring System for Determining the Optimal Slaughter Time of Production Animals Using Computer Vision and Artificial Intelligence(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) FARIAS, Djalma Farias; NASCIMENTO, Manoel Henrique ReisBeef cattle farming faces challenges in optimizing production while meeting demands for meat quality and animal welfare.

The Evil Twin attack, which creates fraudulent access points identical to legitimate ones, poses a serious threat to confidentiality and availability in industrial systems. This study proposes a Unified Detection and Mitigation System (UDMS) that integrates RADIUS-based robust authentication, continuous monitoring using Snort intrusion detection system, and centralized access management via Active Directory. Tested in five progressive scenarios, the system reduced attack success rates from 87% (WPA2-PSK) to just 2%, while maintaining latency below 400ms, with low false positive (6%) and false negative (3%) rates. The research provides a practical framework for securing industrial Wi-Fi networks without compromising operational performance.Item Ozonização como processo de desinfecção da água para consumo humano: eficiência e sustentabilidade(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) FERREIRA, Arthur Joaquim de Araújo; RODRIGUES, Fábio; SILVA, Simone daWater disinfection is essential to eliminate pathogenic microorganisms and ensure sanitary safety.
